The NVIDIA GeForce GTX 980 Review: Maxwell Mark 2
by Ryan Smith on September 18, 2014 10:30 PM ESTThe Test
For the launch of GTX 980 we are using NVIDIA’s press beta drivers for the card, release 334.07 beta. This is the first (semi) public release of the R343 driver set, and coinciding with the release of the Maxwell 2 architecture it also marks the end of support for NVIDIA’s D3D10 GPUs: the 8, 9, 100, 200, and 300 series. Beginning with R343 these products are no longer supported in new driver branches and have been moved to legacy status.
Meanwhile as noted earlier, due to time constraints and hardware problems today we are focusing our coverage on the GTX 980. Next week we will be looking at GTX 980 SLI (hint: it’s fast) and GTX 970.
And on a testing note, as is standard for our reviews we are using our reference Radeon R9 290X for our 290X benchmarks. For this reason we are including both the standard and uber modes for the sake of clarity and completeness. The temperature throttling that the reference 290X suffers from is basically limited to just the reference 290X, as the non-reference/custom models use open air coolers that have no problem dissipating the 290X’s full heat load. Both modes are included for this reason, to demonstrate how a reference 290X performs and how a custom model would perform. At this point you can still buy reference 290X cards, but the vast majority of retail cards will be of the non-reference variety, where the 290X Uber mode’s results will be more applicable.

Yeah. To be honest nobody except ardent Nvidia fanboys would've believed Nvidia would release cards as performance and price competitive as they did, especially the 970. The 980 is honestly a little overpriced compared to a few generations ago as they'll slap a $200 premium on it for Big Maxwell but $330 MSRP for the 970 (if I remember correctly) wasn't bad at all, for generally what, 290/780/290X performance?tuxRoller - Friday, September 26, 2014 - link
It's not too surprising as we saw what the 750ti was like.What is disappointing, though, is that I thought nvidia had made some fundamental breakthrough in their designs where, instead, it looks as though they "simply" enabled a better governor.

It'll be interesting to see how the efficiency suffers once nvidia releases a proper compute die with area dedicated to double precision FP. I have to keep in mind that when factoring in the stripped down die compared to AMD's 290/290X cards, the results aren't as competition. Lowing as they first seem. But if AMD can't counter these cards with their own stripped down gaming only cards then nvidia took the win this generation.tuxRoller - Friday, September 26, 2014 - link
That's an excellent point. I take it you already read the tomshardware review? They're compute performance/W is still good, but not so unbelievable as their gaming performance, but I'm not sure it's b/c this is a gaming only card. Regardless, though, amd needs to offer something better than what's currently available. Unfortunately, I don't think they will be able to do it. There was a lot of driver work than went into making these maxwell cards humgaradante - Friday, September 26, 2014 - link
One thing that really bothers me though is how Anandtech keeps testing the 290/290X with reference cards. Those cards run at 95 C due to the fan control profile in the BIOS and I remember seeing that when people ran those cards with decent nonreference cooling in the 70 C range that power consumption was 15-20+ watts lower. So an AMD die that sacrifices FP64 performance to focus on FP32(gaming, some compute) performance as well as decreasing die size due to the lack of FP64 resources seems like it could be a lot more competitive with Maxwell than people are making it out to be. I have this feeling that the people saying how badly Maxwell trounces AMD's efficiency and that AMD can't possibly hope to catch up are too biased in their thinking.tuxRoller - Saturday, September 27, 2014 - link
Do you have a link to those reviews that show non-reference fans make gpus more efficient? I don't know how that could be possible. Given the temps we're looking at the effects on the conductors should be very, very small.Regarding the reduction in fp performance and gaming efficiency, that's a good point. That may indeed be part of the reason why nvidia has the gaming/compute split (aside from the prices they can charge).

Here's an example of a card with liquid cooling. Factor in the overclock that the nonreference card has and that it draws something like 20 watts less in Furmark and the same in 3Dmark. I could be mistaken on the improved power usage but I do recall seeing shortly after the 290X launch that nonreference coolers helped immensely, and power usage dropped as well. Sadly I don't believe Anandtech ever reviewed a nonreference 290X... which is mind boggling to consider, considering how much nonreference cooling helped that card, even outside of any potential power usage decreases.garadante - Sunday, September 28, 2014 - link

I wonder why they still give these cards these boring numbered names like GTX 980. Except for the Titan, these names kinda suck. Why not at least name it the Maxwell 980 or for AMD's R( 290 series the Hawaii 290. That sounds a lot cooler than GTX or R9. Also, for the last several generations, AMD and Nvidia's numbering system seems to be similar up until AMD ended that with the R9/R7 200 series. Before that, they had the GTX 700 and HD 7000 series, the GTX 600 and HD 6000 series and so on. Then, as soon as AMD changed it up, Nvidia decides to skip the GTX 800's for retail desktop GPUs and jump right up to the 900 series. Maybe they will come up with a fancier name for their next gen cards besides the GTX 1000's.AnnonymousCoward - Saturday, September 27, 2014 - link
Naw, names are much harder to keep track of than numbers that inherently describe relative performance.
