The NVIDIA GeForce RTX 2070 Founders Edition Review: Mid-Range Turing, High-End Price
by Nate Oh on October 16, 2018 9:00 AM ESTCompute & Synthetics
Shifting gears, we'll look at the compute and synthetic aspects of the RTX 2070. Though it has its own GPU in the form of TU106, the hardware resources at hand are similar in progression to what we've seen in TU102 and TU104.
Starting off with GEMM tests, the RTX 2070's tensor cores are pulled into action with half-precision matrix multiplication, though using binaries originally compiled for Volta. Because Turing is backwards compatible and in the same compute capability family as Volta (sm_75 compared to Volta's sm_70), the benchmark continues to work out-of-the-box, though without any Turing optimizations.
At reference specifications, peak theoretical tensor throughput is around 107.6 TFLOPS for the RTX 2080 Ti, 80.5 TFLOPS for the RTX 2080, and 59.7 TFLOPS for the RTX 2070. Unlike the 89% efficiency with the Titan V's 97.5 TFLOPS, the RTX cards are essentially at half that level, with around 47%, 48%, and 45% efficiency for the RTX 2080 Ti, 2080, and 2070 respectively. A Turing-optimized binary should bring that up, though it is possible that the GeForce RTX cards may not be designed for efficient tensor FP16 operations as opposed to the INT dot-product acceleration. After all, the GeForce RTX cards are for consumers and ostensibly intended for inferencing rather than training, which is the reasoning for the new INT support in Turing tensor cores.
In terms of SGEMM efficiency though, the RTX 2070 is hitting a ridiculous 97% of its touted 7.5 TFLOPS, though to be fair the reference specifications here are done manually rather with a reference vBIOS. The other two GeForce RTX cards are at similar 90+% levels of efficiency, though a GEMM test like this is specifically designed for maximum utilization.
The breakdown of the GB4 subscores seems to reveal a similar uplift like we spotted with the Titan V, which had scored in excess of 509,000 points. We'll have to investigate further but Turing and Volta are clearly accelerating some of these workloads beyond what was capable in Pascal and Maxwell.
Given that TU106 has 75% of the hardware resources of TU104, the tessellation performance is in line with expectrations. For reference, we noted earlier that the Titan V scored 703 while the Titan Xp scored 604.

I can't wait for the GTX960 review to finally come out so I can see how it compares!!Meteor2 - Thursday, October 25, 2018 - link

Should have been compared to the 1070 TI FE imo, they dont even sell the 1070 anymore, at least not in the nvidia store in my country. 1070 TI FE is the best bang for your buck right now IMO, if you dont want/need the raytracing capapility and play at 1920x. Personally I recently bought the 1070 TI FE, and have been quite happy with it. Only cost 75% of what a 2070 FE cost, and maxes out my FPS at the resolution I play(1920x1200)TheinsanegamerN - Tuesday, October 16, 2018 - link
Just because the 1070 isnt sold in "the nvidia store in your country" doesnt mean it has ceased to exist, or that it is no longer the market the 2070 is now targeting.btb - Tuesday, October 16, 2018 - link
Well, that might be the case. But does not change that 1070 TI is much better value for money then 1070(and 2070 for that matter). The review not including the "in between" option is not helpful for prospective buyers.. all IMO of course.Death666Angel - Tuesday, October 16, 2018 - link
"1070 TI is much better value for money then 1070"Taking the Techpowerup summary of the relative performance (compared to a 2080Ti) and running it through the cheapest model available from a respectable retailer in Germany, the 1070 is less than .15% better performance/€ in 1080p titles than the 1070, 1.8% better performance/€in 1440p titles and a whopping 3.2% better performance/€ in 2160p titles. "much better value for money" looks different to me. Then there is the fact that there are 53 1070 products and only 36 1070ti ones listed here. And I have to question the sanity and your financial sense of anyone who looks to upgrade from a 1070ti to a 2070. Generational upgrades are usually not worth it without a corresponding process node shrink and the same is true here, especially since the 1070ti is more a 1080 in disguise than a true midrange card.

At least for me, it's not at all about upgrading from a 1070TI to a 2070, but rather which should I purchase to replace my 970. The 1070Ti is roughly $400-450 while the 2070 is $600. That's a huge difference and it's hard to know how big the performance delta is when the article keeps comparing to the 1070 that's effectively been supereseded.If you're buying a 1000 series card, it's a 1060, 1070ti, 1080 or 1080ti; virtually no one is buying a regular 1070 at this point. Honestly I think I'm going to sit out this generation until we have an idea of what this hardware can do for ray tracing and DLSS. I have a feeling these cards (especially the 2070) will struggle mightily to run those settings anywhere near 60fps. So, if I personally don't believe the 2070 will be able to deliver acceptable performance for RTX tech, then I'm leaning towards grabbing a 1000 series for (relatively) cheap.

"If you're buying a 1000 series card, it's a 1060, 1070ti, 1080 or 1080ti; virtually no one is buying a regular 1070 at this point" Any data on this? Or just made up to further your point? What about second hand cards? With a performanc/€ delta of less than % at 1080p, you are making quite bold claims here.Cellar Door - Wednesday, October 17, 2018 - link
The 1070Ti is far better value then 1080 or 1070. Your comparison uses a stock 1070Ti - a card which only makes sense overclocked(due to Nvidia banning any factory OC models). When overclocked, 1070Ti is 7% lower perf then an OC 1080 for a lot less.Oh and since 1070Ti was just launched last October, they are perfect to grab on the used market as all cards will still have 2 years of warranty left. I picked up a mint used 1070Ti for $300.
