The NVIDIA GeForce GTX 980 Review: Maxwell Mark 2
by Ryan Smith on September 18, 2014 10:30 PM ESTSynthetics
As always we’ll also take a quick look at synthetic performance. These tests mainly serve as a canary for finding important architectural changes, and with the exception of pixel throughput we are not expecting any major changes for GTX 980 and GM204.
GM204 is designed to have an ever-so-slightly higher triangle throughput rate than GK110 – 16 tris/clock versus 15 tris/clock, and sure enough the GTX 980 comes out on top in TessMark, slightly edging out the GTX 780 Ti. The difference is only very slight here, and though GM204 should be a bit more powerful than GK110 in practice it’s a dead heat.
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.
Beginning with Maxwell NVIDIA reduced their texture-to-compute ratio from 12:1 to 16:1. As a result of this change Maxwell GPUs have fewer texture units than comparable Kepler GPUs. Compounding this effect is the fact that Maxwell CUDA cores are more efficient than Kepler CUDA cores, leading to NVIDIA placing fewer cores overall and further reducing the texture fill rate.
As a result the GTX 980 is not texture fillrate competitive with any of the GK110 cards. It is competitive with the GK104 cards, but only because these cards had the same number of texture units at 128. NVIDIA has told us that they believe this new ratio is a better fit for modern workloads, and judging from the performance we’re seeing elsewhere it would appear that NVIDIA is right.
On the other hand, thanks to NVIDIA’s newer 3rd generation delta color compression technology, our 3DMark pixel fillrate performance is through the roof. GTX 980 comes very close to doubling the throughput of our GK110 cards and more than doubles the throughput of the GK104 cards, reflecting the fact that it has 64 ROPs and more importantly has the available bandwidth to put them to good use.
This benchmark in a nutshell is why NVIDIA can deliver chart-topping performance despite having only 2/3rds the memory bandwidth of GTX 780 Ti. By improving their color compression to this point, NVIDIA can significantly reduce their memory bandwidth requirements Maxwell 2, allowing them to do more with less. In real games the result won’t be anywhere near this remarkable since this is a pure pixel fillrate test, but it goes to show that NVIDIA has been able to expand their effective memory bandwidth in concert with their ROP and shader performance improvements.

Nvidia and AMD havent moved to 22 because they don't have the funding. Intel has tens of billions to blow away in R&D. Broadwells going to be released in 2015, and its 14nm.Hrel - Monday, September 22, 2014 - link
In light of Nvidia not even trying to reduce manufacturing nodes It would be really nice to see them go on the offensive in the price war. $300 for the GTX980, everything lower from there. Probably not now, but like, spring 2015, that'd be great! Make good and sure to wipe out all the hold outs (like myself) keeping their old cards because they still play everything they play on 1080p. Kinda, get all your customers caught up on hardware in the same upgrade time frame.Then when they finally do drop nodes they can focus on making every card they sell run games at 8K resolution.

Hate to break the news to you, but if you want to game at high level (above 1080p), you need to pay at high level. There is nothing new about that in the entire history of PC enthusiast building and gaming either for those of us who remember making the "huge leap" from a 15" 1024x768 resolution CRT monitor to a whopping 19" 1600x1200 CRT monitor. At least not in the 20 years since I've been involved with it anyway.Besides all that, that's why GPU makers offer cards for different budgets. If you can't afford their top tier products, you can't afford to game top tier. Period and end of discussion.

It seems as though the big improvement nvidia has made is to enable cpu-level scheduling/dvfs granularity into their chip. However, once all cores are engaged it ends up using as much power as its predecessor (see tomshardware).What I really want to know is how much of this due to purely driver-level changes.

Exceptional design. The sad thing is that NVIDIA will take forever to release a 30 SMM Maxwell GPU and once it finally does, it would cost a ton; even later on when they release a "budget" version for an unreasonable price of around $650 it would be too late - the great performance potential of today wouldn't be so great tomorrow. Striving for and building amazing GPUs is the right way forward, not empowering the people with them is a crime. Whatever happened to $500 flagship products?Rhodie - Wednesday, September 24, 2014 - link
Just got a GTX970, and only latest Nvidia drivers will install for 9xx series cards it seems. Unfortunately the latest drivers totally screw up some programs that use CUDA, seem to hide itspresence from programs lile Xillisoft Video Convertor Ultimate:-/ No response of course from either Nvidia or Xillisoft regarding the problem. Wonder how many other programs the drivers break?

Geeze. Anandtech, do an updated best value graphics card list because since the launch of the 970/980 retailers are giving some serious price cuts to 770/780/780 Ti's. Newegg has a 780 for less than $300 after rebate and just a hair over $300 before rebate. I'm seeing 780 Ti's for ~$430 and 770s for ~$240. I am amazed to see price cuts this deep since I haven't seen them the last several generations and considering how overpriced these cards were. But while supplies last and prices hold/drop, this completely flips price/performance on it's head. I feel bad recommending an AMD 290 Tri-X to a friend a couple months back now. xDgaradante - Thursday, September 25, 2014 - link
Please do an updates best value graphics card* Where are my manners! D:jman9295 - Friday, September 26, 2014 - link
Newegg has an Asus DirectCU II GTX 780 selling in the $290 range after a mail in rebate, promo code and discount. It also comes with a pre-order copy of the new Borderlands game. That has to be the best value to performance GPU out right now. It is almost a full $100 less than the cheapest non-reference R9 290 on newegg and $40 less than the cheapest reference R9 290 which is crazy since this same Asus GTX 780 was selling for over $550 just last month with no free games (and still is on Amazon for some reason).mixer4x - Thursday, September 25, 2014 - link
I feel bad for having just bought the 290 tri-x just a month ago! =(I bought it because you never know when the new cards will be released and how much they will cost. Unfortunately, the new cards came out too soon!
