Synthetics
As always we’ll also take a quick look at synthetic performance. The 290X shouldn’t pack any great surprises here since it’s still GCN, and as such bound to the same general rules for efficiency, but we do have the additional geometry processors and additional ROPs to occupy our attention.
Right off the bat then, the TessMark results are something of a head scratcher. Whereas NVIDIA’s performance here has consistently scaled well with the number of SMXes, AMD’s seeing minimal scaling from those additional geometry processors on Hawaii/290X. Clearly Tessmark is striking another bottleneck on 290X beyond simple geometry throughput, though it’s not absolutely clear what that bottleneck is.
This is a tessellation-heavy benchmark as opposed to a simple massive geometry bencehmark, so we may be seeing a tessellation bottleneck rather than a geometry bottleneck, as tessellation requires its own set of heavy lifting to generate the necessary control points. The 12% performance gain is much closer to the 11% memory bandwidth gain than anything else, so it may be that the 280X and 290X are having to go off-chip to store tessellation data (we are after all using a rather extreme factor), in which case it’s a memory bandwidth bottleneck. Real world geometry performance will undoubtedly be better than this – thankfully for AMD this is the pathological tessellation case – but it does serve of a reminder of how much more tessellation performance NVIDIA is able to wring out of Kepler. Though the nearly 8x increase in tessellation performance since 5870 shows that AMD has at least gone a long way in 4 years, and considering the performance in our tessellation enabled games AMD doesn’t seem to be hurting for tessellation performance in the real world right now.
Moving on, we have our 3DMark Vantage texture and pixel fillrate tests, which present our cards with massive amounts of texturing and color blending work. These aren’t results we suggest comparing across different vendors, but they’re good for tracking improvements and changes within a single product family.
Looking first at texturing performance, we can see that texturing performance is essentially scaling 1:1 with what the theoretical numbers say it should. 36% better texturing performance over 280X is exactly in line with the increased number of texture units versus 280X, at the very least proving that 290X isn’t having any trouble feeding the increased number of texture units in this scenario.
Meanwhile for our pixel fill rates the results are a bit more in the middle, reflecting the fact that this test is a mix of ROP bottlenecking and memory bandwidth bottlenecking. Remember, AMD doubled the ROPs versus 280X, but only gave it 11% more memory bandwidth. As a result the ROPs’ ability to perform is going to depend in part on how well color compression works and what can be recycled in the L2 cache, as anything else means a trip to the VRAM and running into those lesser memory bandwidth gains. Though the 290X does get something of a secondary benefit here, which is that unlike the 280X it doesn’t have to go through a memory crossbar and any inefficiencies/overhead it may add, since the number of ROPs and memory controllers is perfectly aligned on Hawaii.

Perhaps they knew it was unsustainable from the beginning, but short term gains are generally what motivate managers when the develop pricing strategies, because bonus. Make hay whilst the sun shines, or when AMD is 8 months late.chizow - Saturday, October 26, 2013 - link
Possibly, but now they have to deal with the damaged goodwill of some of their most enthusiastic, spendy customers. I can't count how many times I've seen it, someone saying they swore off company X or company Y because they felt they got burned/screwed/fleeced by a single transaction. That is what Nvidia will be dealing with going forward with Titan early adopters.Sancus - Thursday, October 24, 2013 - link
AMD really needs to do better than a response 8 months later to crash anyone's parade. And honestly, I would love to see them put up a fight with Maxwell at a reasonable time period so they have incentive to keep prices lower. Otherwise, expect Nvidia to "overprice" things next generation as well.When they have no competition for 8 months it's not unsustainable to price as high as the market will bear, and there's no real evidence that Titan was economically overpriced because it's not like there was a supply glut of Titans sitting around anywhere, in fact they were often out of stock. So really, Nvidia is just pricing according to the market -- no competition from AMD for 8 months, fastest card with limited supply, why WOULD they price it at anything below $1000?

My reply would be that they've never had to price it at $1000 before, and we have certainly seen this level of advancement from one generation to the next in the past (7900GTX to 8800GTX, 8800GTX to GTX 280, 280 GTX to 480 GTX, etc), so it's not completely ground-breaking performance increases even though Kepler overall outperformed historical improvements by ~20%, imo.Also, the concern with Titan isn't just the fact it was priced at ungodly premiums this time around, it's the fact it held it's crown for such a relatively short period of time. Sure Nvidia had no competition at the $500+ range for 8 months, but that was also the brevity of Titan's reign at the top. In the past, a flagship in that $500 or $600+ range would generally reign for the entire generation, especially one that was launched half way through that generation's life cycle. Now Nvidia has already announced a reply with the 780 Ti which will mean not one, but TWO cards will surpass Titan at a fraction of it's price before the generation goes EOL.
Nvidia was clearly blind-sided by Hawaii and ultimately it will cost them customer loyalty, imo.

$1000 cards are fine, since the Titan is a cheap compute unit compared to the Quadro K6000 and the 690 is a dual-GPU card (Dual-GPU has always been in the $800+ range).What we should see is the 780 (Ti?) go down in price and match the R9-290x, much to the rejoicing of all!
Nvidia got away with $650-750 on the 780 because they could, and THAT is why competition is important, and why I pay attention to AMD even if I have no reason to buy from them over Nvidia (driver support on Linux is a joke). Now they have to match. Much of the same happens in the CPU segement.

For those that actually bought the Titan as a cheap compute card, sure Titan may have been a good buy, but I doubt most Titan buyers were buying it for compute. It was marketed as a gaming card with supercomputer guts and at the time, there was still much uncertainty whether or not Nvidia would release a GTX gaming card based on GK110.I think Nvidia preyed on these fears and took the opportunity to launch a $1K part, but I knew it was an unsustainable business model for them because it was predicated on the fact Nvidia would be an entire ASIC ahead of AMD and able to match AMD's fastest ASIC (Tahiti) with their 2nd fastest (GK104). Clearly Hawaii has turned that idea on it's head and Nvidia's premium product stack is crashing down in flames.
Now, we will see at least 4 cards (290/290X, 780/780Ti) that all come close to or exceed Titan performance at a fraction of the price, only 8 months after it's launch. Short reign indeed.

The market dictates pricing. As they said, they sell every Titan immediately, so they could probably charge more. But that's because it has more value than you seem to understand. It is a PRO CARD at it's core. Are you unaware of what a TESLA is for $2500? It's the same freaking card with 1 more SMX and driver support. $1000 is GENEROUS whether you like it or not. Gamers with PRO intentions laughed when they saw the $1000 price and have been buying them like mad ever since. No parade has been crashed. They will continue to do this pricing model for the foreseeable future as they have proven there is a market for high-end gamers with a PRO APP desire on top. The first run was 100,000 and sold in days. By contrast Asus Rog Ares 2 had 1000 unit first run and didn't sell out like that. At $1500 it really was a ripoff with no PRO side.I think they'll merely need another SMX turned on and 50-100mhz for the next $1000 version which likely comes before xmas :) The PRO perf is what is valued here over a regular card. Your short-lived statement makes no sense. It's been 8 months, a rather long life in gpus when you haven't beaten the 8 month old card in much (I debunked 4k crap already, and pointed to a dozen other games where titan wins at every res). You won't fire up Blender, Premiere, PS CS etc and smoke a titan with 290x either...LOL. You'll find out what the other $450 is for at that point.

Yes and as soon as they released the 780, the market corrected itself and Titans were no longer sold out anywhere, clearly a shift indicating the price of the 780 was really what the market was willing to bear.Also, there are more differences with their Tesla counterparts than just 1 SMX, Titan lacks ECC support which makes it an unlikely candidate for serious compute projects. Titan is good for hobby compute, anything serious business or research related is going to spend the extra for Tesla and ECC.
And no, 8-months is not a long time at the top, look at the reigns of previous high-end parts and you will see it is generally longer than this. Even the 580 that preceded it held sway for 14-months before Tahiti took over it's spot. Time at the top is just one part though, the amount which Titan devalued is the bigger concern. When 780 launched 3 months after Titan, you could maybe sell Titan for $800. Now that Hawaii has launched, you could maybe sell it for $700? It's only going to keep going down, what do you think it will sell for once 780Ti beats it outright for $650 or less?

I noticed your comments on the Tahiti pricing fiasco 2 years ago and generally skip through the comment section to find yours because they're top notch. Exactly what I was thinking with the $550 price point, finally a top-tier card at the right price for 28nm. Long live sanity.chizow - Saturday, October 26, 2013 - link
Thanks! Glad you appreciated the comments, I figured this business model and pricing for Nvidia would be unsustainable, but I thought it wouldn't fall apart until we saw 20nm Maxwell/Pirate Islands parts in 2014. Hawaii definitely accelerated the downfall of Titan and Nvidia's $1K eagle's nest.
