Final Words

Bringing this review to a close, NVIDIA’s latest product launch has given us quite a bit to digest. Not only are we looking at NVIDIA’s latest products for the high volume mainstream desktop video card market, but we’re doing so through the glasses of a new generation of GPUs. With the GeForce GTX 750 series we are seeing our first look at what the next generation of GPUs will hold for NVIDIA, and if these cards are an accurate indication of what’s to follow then we’re being setup for quite an interesting time.

Starting from an architectural point of view, it’s clear from the very start that Maxwell is both a refresh of the Kepler architecture and at the same time oh so much more. I think from a feature perspective it’s going to be difficult not to be a bit disappointed that NVIDIA hasn’t pushed the envelope here in some manner, leaving us with a part that as far as features go is distinctly Kepler. Complete support for Direct3D 11.1 and 11.2, though not essential, would have been nice to have so that 11.2 could be the standard for new video cards in 2014. Otherwise I’ll fully admit I don’t know what else to expect of Maxwell – the lack of a new Direct3D standard leaves this as something of a wildcard – but it means that there isn’t a real marquee feature for the architecture to evaluate and marvel at.

On the other hand, the lack of a significant feature changes means that it’s much easier to evaluate Maxwell next to Kepler in the area where NVIDIA did focus: efficiency. This goes for power efficiency resource/compute efficiency, and space efficiency. Utilizing a number of techniques NVIDIA set out to double their performance per watt versus Kepler – a design that was already power efficient by desktop GPU standards – and it’s safe to say that they have accomplished this. With a higher resource efficiency giving NVIDIA additional performance with less hardware, and power optimizations bringing that power consumption down by dozens of watts, NVIDIA has done what in previous generations would have taken a die shrink. The tradeoff is that NVIDIA doesn’t have that die shrink, so die sizes grow in the process, but even then the fact that they packed so much more hardware into GM107 for only a moderate increase in die size is definitely remarkable from an engineering perspective.

Efficiency aside, Maxwell’s architecture is something of an oddity at first, but given NVIDIA’s efficiency gains it’s difficult to argue with the outcome. The partitioning of the SMM means that we have partitions that feel a lot like GF100 SMs, which has NVIDIA going backwards in a sense due to the fact that significant resource sharing was something that first became big with Kepler. But perhaps that was the right move all along, as evidenced by what NVIDIA has achieved. On the other hand the upgrade of the compute feature set to GK110 levels is good news all around. The increased efficiency it affords improves performance alongside the other IPC improvements NVIDIA has worked in, plus it means that some of GK110’s more exotic features such as dynamic parallelism and HyperQ are now a baseline feature. Furthermore the reduction in register pressure and memory pressure all around should be a welcome development; compared to GK107 there are now more registers per thread, more registers per CUDA core, more shared memory per CUDA core, and a lot more L2 cache per GPU. All of which should help to alleviate memory related stalls, especially as NVIDIA is staying on the 128-bit bus.

With that in mind, this brings us to the cards themselves. By doubling their performance-per-watt NVIDIA has significantly shifted their performance both with respect to their own product lineup and AMD’s lineup. The fact that the GTX 750 Ti is nearly 2x as fast as the GTX 650 is a significant victory for NVIDIA, and the fact that it’s nearly 3x faster than the GT 640 – officially NVIDIA’s fastest 600 series card without a PCIe power plug requirement – completely changes the sub-75W market. NVIDIA wants to leverage GM107 and the GTX 750 series to capture this market for HTPC use and OEM system upgrades alike, and they’re in a very good position to do so. Plus it goes without saying that compared to last-generation cards such as the GeForce GTX 550 Ti, NVIDIA has finally doubled their performance (and halved their power consumption!), for existing NVIDIA customers looking for a significant upgrade from older GF106/GF116 cards.

But on a competitive basis things are not so solidly in NVIDIA’s favor. NVIDIA does not always attempt to compete with AMD on a price/performance basis in the mainstream market, as their brand and retail presence gives them something they can bank on even when they don’t have the performance advantage. In this case NVIDIA has purposely chosen to forgo chasing AMD for the price/performance lead, and as such for the price the GeForce GTX 750 cards are the weaker products. Radeon R7 265 holds a particularly large 19% lead over GTX 750 Ti, and in fact wins at every single benchmark. Similarly, Radeon R7 260X averages a 10% lead over GTX 750, and it does so while having 2GB of VRAM to GTX 750’s 1GB.

On a pure price/performance basis, the GTX 750 series is not competitive. If you’re in the sub-$150 market and looking solely at performance, the Radeon R7 260 series will be the way to go. But this requires forgoing NVIDIA’s ecosystem and their power efficiency advantage; if either of those matter to you, then the lower performance of the NVIDIA cards will be justified by their other advantages. With that said however, we will throw in an escape clause: NVIDIA has hard availability today, while AMD’s Radeon R7 265 cards are still not due for about another 2 weeks. Furthermore it’s not at all clear if retailers will hold to their $149 MSRP due to insane demand from cryptocoin miners; if that happens then NVIDIA’s competition is diminished or removed entirely, and NVIDIA wins on price/performance by default.

Wrapping things up, as excited as we get and as focused as we are on desktop cards, it’s hard not to view this launch as a preview of things to come. With laptop sales already exceeding desktop sales, it’s a foregone conclusion that NVIDIA will move more GM107 based video cards in mobile products than they will in desktops. With GK107 already being very successful in that space and GM107 doubling NVIDIA’s performance-per-watt – and thereby doubling their performance in those power-constrained devices – it means that GM107 is going to be an even greater asset in the mobile arena. To that end it will be very interesting to see what happens once NVIDIA starts releasing the obligatory mobile variants of the GTX 750 series, as what we’ve seen today tells us that we could be in for a very welcome jump in mobile performance.

    You are only able to say AMD is winning with 265 because of magical pricing that probably won't exist, just like 290x/290 are not $550/400, which we now know are really $709/550 (amazon's lowest pricing, which is below newegg on 290, about even on 290x - amazon has 290x in stock). At least most are out of stock now, so maybe they're selling better or it really is just a shortage of chips like PNY says. I'm guessing the shortage of chips that can run 1ghz is causing problems and higher pricing on 290/290x, not selling like crazy. If they were selling like crazy to miners etc AMD would have had a quarter like NV had where GPU revenues rose 14% on the backs of HIGH-END gpu sales in a 11% down PC market. The 290/290x are AMD's high end, yet selling out means zero profits? So High-End isn't selling much and is just a shortage of 1ghz chips then right? 10mil console chips were all of AMD's gpu profits (10mil x $12 each=120mil pretty much exactly AMD's profits).

    I don't see how Anandtech etc can say crypto mining is insane, when AMD's quarterly report shows miners must not be buying them much at all after the first rush at launch. Otherwise they would have made more than just console money. AMD said they get low double digits on consoles now (so not mid which would be 15%, if closer to 15% profits would be like 150mil), which is 8.2mil units already purchased in retail consoles, and another ~2mil in transit or already in MS/Sony being boxed up for more retail boxes. AMD gets their money long before we see it on the shelf in a console (hence the ~2mil in transition). MS/Sony don't pay AMD AFTER the console sales, they pay them BEFORE it gets anywhere near a box on a shelf. So AMD has already sold more than the shelf sales show.

    On the flipside, NV has a quarter with ~$145mil in profits and basically ALL of that is from GPU's. So again, if AMD is selling out (in any volume that is) how come they didn't have $240mil in profits or something like this? Why no profits from GPU's showing up? There must be a real shortage that isn't due to them selling out like crazy, but instead due to manufacturing chips that can do 1ghz without throttling. This is the ONLY assumption that fits the financial data. Miners are NOT buying these in massive quantities. AMD just can't make enough to satisfy anyone, thus the price goes through the roof and companies like PNY say they can't get chips. In turn this causes AMD's MSRP to basically be magical fairy dust pricing which may not be REALITY for many months to come :( Your price perf story doesn't fit. AMD is winning nothing.

    Let me know when you can buy a 290 or 290x for $400 or $550. Let me know when you can buy a 265 for $149. This may turn out to be real for 265 but it isn't now and Anandtech shouldn't be comparing cards that don't even exist yet and pricing is unknown. I mean the reviews of 290/290x said "these are awesome buys", blah blah, but at $709 for 290x isn't it a terrible deal with 780TI OC models going for the same exact price but winning by 20%?
    http://hardocp.com/article/2014/02/10/msi_geforce_...
    OC 290x vs. OC 780ti.
    "The current street price of the ASUS R9 290X DirectCU II OC is $699.99 at several etailers (if you can find it in stock), representing a significant bump from its MSRP of $569.99. If you were to compare the two cards at MSRP, then the 20% performance difference between these could easily be accounted for with the 20% difference in price. However, at the current street pricing, the MSI GeForce GTX 780 Ti GAMING 3G simply slaps the ASUS R9 290X DirectCU II OC around with a large rainbow trout."

    Slaps AMD around like a rainbow trout? OK, OC & price contest settled then. Custom cooling won't magically trump 780TI and MSRP for 290x of $550 and reality for a card that can actually do AMD's magical ref speeds and up is a $150 difference. I don't know why anyone would buy a 265 for compute (or any card in this category, stupid to benchmark this for these low end models), so maybe AMD will actually get to $150 on them. But giving reviews based on pricing we now know may not happen on cards that aren't even available yet vs. a HARD LAUNCH with OC models already out far above what is tested here by anandtech is a bit of a pipe dream at best.

    "In short, you'll have to pardon our skepticism that Radeon R7 265 will show up on time and at the price point AMD is claiming. We've seen fingers pointed at gun-shy add-in board partners, performance-thirsty cryptocurrency miners, price-gouging retailers, and foundries unable to keep up with supply. But at the end of the day, we're left wondering why AMD is setting prices if it can't control what you pay for its hardware? After piling praise onto the Radeon R9 280X at $300 and 290X at $550, it's our credibility on the line now, and we've been burnt too many times to give you guidance on a card you can't buy yet."

    Just one of 3-4 of their paragraphs outlining the pricing problems and AMD's magical prices :) You get a whole page dedicated to AMD's pricing issues at tomshardware...LOL. Tomshardware is worried about credibility claiming AMD's pricing is real.

    Even anandtech says it's probably magical pricing, so why compare the 265 to 750ti as if 265 will actually be $149?
    http://www.anandtech.com/show/7754/the-amd-radeon-...
    "but unless something changes to bring the other Pitcairn cards back down to their MSRPs, then $149 for 265 may be an unreasonable expectation"

    "The lack of selection has done no favors for the pricing, leading to 260 prices starting at $125. This is $15 above MSRP – a significant difference for this segment of the market – and just a stone’s throw away from the 260X at current prices."

    More comments about lack of 250's etc also. AMD can't seem to put a card out at MSRP. How do you come to the conclusion AMD wins at price perf, when no card is MSRP? Reality check please pal. If 260x is supposed to be $120 for new MSRP how is this possible given we already have regular 260 at $125? Again magical pricing is used for your statements not REALITY.

    Current pricing on 290x/780TI are the same, and 780TI smoke it slapping it around like a rainbow trout. :) Not sure how you get AMD is winning from all of these comments. Yeah if you include magical pricing that may ONE DAY exist, but not REALITY for right now. You keep living in your fantasy world, I'll just stay in reality thanks. I fail to see how AMD will be able to keep up with R&D NV is clearly investing in GPU's. I'm not sure why anandtech even bothered to benchmark the ref design, when they admit NOBODY will be shipping them.
    "NVIDIA’s partners will be launching with custom cards from day-one, and while NVIDIA has put together a reference board for testing and validation purposes, the partners will not be selling that reference board. Instead we’ll be seeing semi-custom and fully-custom designs; everyone has their own cooler, a lot of partners will be using the NVIDIA reference PCB, and others will be rolling out their own PCBs too."

    So why test them? That isn't reality as they clearly point out.
    http://www.anandtech.com/show/7764/the-nvidia-gefo...
    I don't get it. Further showing their AMD love they left the Zotac out of most high end benchmarks and only used ref. What? After clearly stating REF won't even be sold why KEY on REF designs in your benchmarks? Oh right, they only have an AMD portal on anandtech...Never mind...LOL. I get it. :)

    http://www.newegg.com/Product/ProductList.aspx?Sub...
    For $5-10 more over a REAL MSRP on 750ti you get 1176/1255 or 1202/1281 which are both WAY over stock.

    If maxwell is designed for mobile gaming so "who cares" then AMD is designed for compute/mining crap that has just about NOTHING to do with gaming so "who cares" too right? I mean if you want to win synthetic crap buy AMD. If you want to win in gaming buy NV. It would seem NV has the right idea for their audience. Also I wasn't aware Intel has ever put anything out in GPU that is damned good. LOL. They can't even catch BROKE AMD's Kaveri.

    You're basing your price perf comment on pricing that is not REAL. Get back to us when AMD puts out something that sells at their MSRP. Until then their PRICE is FAKE, and price to performance crap is meaningless unless you talk in terms of REAL pricing. In which case NV looks great as hardocp shows.

    "On a pure price/performance basis, the GTX 750 series is not competitive. If you’re in the sub-$150 market and looking solely at performance, the Radeon R7 260 series will be the way to go."
    Fantasy pricing makes this comment moot.

    "With that said however, we will throw in an escape clause: NVIDIA has hard availability today, while AMD’s Radeon R7 265 cards are still not due for about another 2 weeks. Furthermore it’s not at all clear if retailers will hold to their $149 MSRP due to insane demand from cryptocoin miners; if that happens then NVIDIA’s competition is diminished or removed entirely, and NVIDIA wins on price/performance by default."

    That comment is REALITY. We know they won't be MSRP if recent history is any indication. They have been so wrong that tomshardware can't recommend anything on MSRP now. Anyone making comparisons on MSRP for AMD at this point is not credible. Hardocp, tomshardware etc all note it's currently FAKE pricing. Until that changes any site should be writing reviews with REAL pricing in the recommendations/conclusions and people like you should just avoid using phrases like "price performance" ;) AMD is losing everything on price performance when using REAL pricing. I don't know why anyone even quotes MSRP. It's merely a SUGGESTED price. You should just quote the lowest newegg or amazon price as that is the lowest you can get MSRP or not. IF it's NOT a hard launch so you can get that pricing, you shouldn't be reviewing something (since I can't REALLY buy it and have no idea of the REAL price). Get it?

    NV needs to say Titan Black is MSRP of $550 I guess and start acting like AMD. Reviews would have to be written with MSRP conclusions for them then too right? Has anyone gotten a 290 for $400 or 290x for $550? Doubtful. Time for NV to join the lying game and soft launches with pricing that may not come for months?

    From anandtech's 265 article:
    "Finally, for the time being NVIDIA’s competition is going to be spread out, leaving a lack of direct competition for AMD’s latest arrivals. With the retirement of GTX 650 Ti Boost, NVIDIA doesn’t currently have a product directly opposite 265 at $149, with GTX 660 well above it and GTX 650 Ti well below it. On the other hand, NVIDIA’s closest competition for 260 as it stands is GTX 650 Ti, though this would shift if 260X cards quickly hit their new $119 MSRP."

    Totally false considering all AMD pricing is fake right? If 260x QUICKLY hits $119 new MSRP? ROFL. Until they HIT that pricing shut up please. NV doesn't have a direct competitor to $149 265? Yeah because it won't REALLY be $149...LOL. 270 shows it, 260 shows it, 290, 290x, 280, 280x...jeez. Does AMD have a card that really is MSRP? So anandtech is comparing the NV stack to a magically priced fairy dust AMD stack right? That seems a bit unfair considering all the data on AMD pricing currently and EVERY site commenting on it. They continue to heap praise on AMD in reviews based on fake pricing. You can't write a whole page on how bad AMD's pricing situation is then go ahead and write conclusions and recommendations on that fake pricing as if it is real or will be real at some point MAYBE. Misleading the public at best, which is why tomshardware/hardocp etc backed off now. NV wins by default, until AMD puts out a real MSRP card. Anandtech still gives AMD the benefit of the doubt giving NV an escape clause...It should be the other way around. AMD needs that clause as no card they've released recently is MSRP.

    AMD's MSRP is very real, the issue is supply cannot meet demand. AMD only sees the money they make selling cards to vendors, if they had direct supply control (AMD badged products) they could be making money hands over fists with the inflation, but AMD isn't in the position to do that. They sell their chipsets at the stipulated pricepoint to their vendors, and the vendors then either pass on the savings, or squeeze supply and drive up prices for retailers. If they pass on the savings, then ultimately retailers are capitalizing on the consumer's willingness to pay more, but AMD, ultimately, will see no profits from this, and their sales will be hurt by lower flow due to high prices.

    Plenty of people bought 2XX series cards for their MSRP before LiteCoin made the prices skyrocket. To date, only the 290 series is still hyper inflated. And the MSRPs being determined there are from the vendors, not AMD.

    The 280x are still priced 50% to 100% over MSRP, too. They're supposed to be $300, but you can't find cheaper than $450, with $5-600 quite common. The R9 270x runs about $50-$100 over MSRP (25-50%). Reply

    That tiny fraction currently buys more GPUs than the avg consumer. Thus the demand for AMD's high end GPUs. Reply
