3DMark, Unigine Heaven and Overclocking
Let's look at a set of tests from more standard benchmarks like Unigine Heaven and the new 3DMark benchmark.
I consider these tests to be somewhat of a "best case" for all the cards in our comparison. We aren't using our frame capture system, we aren't measuring frame latency, nothing like that; I think this should give you an idea of graphics performance if each vendor had the best result for each game.
The 3DMark Fire Strike results look very familiar to those of you that read the previous benchmark pages. The new Titan X based on Pascal is just unmatched in single card configurations.
Under Unigine Heaven, the new Titan X is 41% faster than the GTX 1080 and is exactly 2x the performance of AMD's Radeon Fury X.
I didn't have much time to spend tweaking the new Titan X, and Precision X doesn't support the card yet, but I was able to utilize the latest beta of MSI Afterburner to get us to a +150 MHz frequency offset with 120% power target.
That results in a base clock of 1568 MHz and a typical boost clock of 1681 MHz. That is nearly 10% higher than reference speeds. In practice, and as you'll see in the next set of graphs, I saw clock speeds nearly hitting 1900 MHz consistently.
Clock Speed Consistency
Looping Unigine Heaven for 10 minutes to warm up the GPU for testing, I used GPU-Z to capture the clock speed and temperature of the GPU in real time to see how consistent the clock speeds were at both stock and overclocked settings.
I continue to be less than impressed with the clock speed stability of Pascal at stock settings. It seems to me that NVIDIA might be slightly aggressive with target clock speeds and voltages, result in variance that you see here.
Once overclocked, things are not only faster, but considerably more consistent. This is likely because we have increased the power limit.
With everything at stock, the average frequency in this test over a long period was 1660 MHz; when overclocked with a +150 MHz offset and increased power target, the average bumps all the way to 1838 MHz!
Ryan, too bad there is no
Ryan, too bad there is no benchmark of other games such as Six Siege, Overwatch etc.
Think that many of these games is crucial to people if they are seriously buying this GPU.
I know you can’t benchmark every game, but should atleast go for the most popular ones.
Ryan, first off – THANK YOU!
Ryan, first off – THANK YOU! You and your staff did an outstanding job putting together this review. I can easily see there was a lot of work done here. I also understand that not every review is perfect, so I may be a bit more forgiving with regards to any mistakes made – though I really didn’t see any and you approached this review with a ‘just the facts’ mentality. Some things I would like to make note of based upon the information and data provided within your Titan X review, other reviews I have read thus far, and my current PC hardware configuration (two GTX980Ti cards in SLI):
1) Titan X performance is near the performance of two GTX980Ti cards in SLI, let alone two GTX980 cards, which by the way can’t even achieve correct playable frame rates at 4K resolutions due more to the limitation of the VRAM (only 4GB each card).
2) Almost 50% of games today do not scale well with 2-way SLI. 3-way and higher is even worse. This alone is a valid argument for those seeking the best performance without all the technical issues that SLI induces to buy a Titan X. Using a single card means no micro stutter, frame rendering lag, required need for a SLI HB bridge, and of course the fact that double the performance is not achieved in 99% of games currently on the market.
3) A single GTX1080 can not play a vast majority of games at 4K resolutions without having to turn down some settings, and buying two GTX1080 cards to do so will cost you as much as a single Titan X AND you will still have the issues induced by SLI, especially more so with DX12 games.
Based upon these observations, one would conclude that if you are an avid enthusiast PC gamer and play games at the higher resolutions, the Titan X is the best buy for the returned level of performance and least amount of technical issues and limitations associated with running two or more cards in an SLI configuration. One could also argue that if there were a need to ‘grow’ in performance capability, then worst case you could always add a second Titan X card 😉
FP16 performance in GP102 is
FP16 performance in GP102 is just 1.5% of FP32 performance.
This year GPUs will be up to twice as efficient!
