The NVIDIA GeForce GTX Titan X Review
by Ryan Smith on March 17, 2015 3:00 PM ESTBattlefield 4
Kicking off our 2015 benchmark suite is Battlefield 4, DICE’s 2013 multiplayer military shooter. After a rocky start, Battlefield 4 has since become a challenging game in its own right and a showcase title for low-level graphics APIs. As these benchmarks are from single player mode, based on our experiences our rule of thumb here is that multiplayer framerates will dip to half our single player framerates, which means a card needs to be able to average at least 60fps if it’s to be able to hold up in multiplayer.
After stripping away the Frostbite engine’s expensive (and not wholly effective) MSAA, what we’re left with for BF4 at 4K with Ultra quality puts the GTX Titan X in a pretty good light. At 58.3fps it’s not quite up to the 60fps mark, but it comes very close, close enough that the GTX Titan X should be able to stay above 30fps virtually the entire time, and never drop too far below 30fps in even the worst case scenario. Alternatively, dropping to Medium quality should give the GTX Titan X plenty of headroom, with an average framerate of 94.8fps meaning even the lowest framerate never drops below 45fps.
From a benchmarking perspective Battlefield 4 at this point is a well optimized title that’s a pretty good microcosm of overall GPU performance. In this case we find that the GTX Titan X performs around 33% better than the GTX 980, which is almost exactly in-line with our earlier performance predictions. Keeping in mind that while GTX Titan X has 50% more execution units than GTX 980, it’s also clocked at around 88% of the clockspeed, so 33% is right where we should be in a GPU-bound scenario.
Otherwise compared to the GTX 780 Ti and the original GTX Titan, the performance advantage at 4K is around 50% and 66% respectively. GTX Titan X is not going to double the original Titan’s performance – there’s only so much you can do without a die shrink – but it continues to be amazing just how much extra performance NVIDIA has been able to wring out without increasing power consumption and with only a minimal increase in die size.
On the broader competitive landscape, this is far from the Radeon R9 290X/290XU’s best title, with GTX Titan X leading by 50-60%. However this is also a showcase title for when AFR goes right, as the R9 295X2 and GTX 980 SLI both shoot well past the GTX Titan X, demonstrating the performance/consistency tradeoff inherent in multi-GPU setups.
Finally, shifting gears for a moment, gamers looking for the ultimate 1440p card will not be disappointed. GTX Titan X will not get to 120fps here (it won’t even come close), but at 78.7fps it’s well suited for driving 1440p144 displays. In fact it’s the only single-GPU card to do better than 60fps at this resolution.

If the most recent slides (allegedly leaked from AMD) hold true, the 390x will be at least as fast as the Titan X, though with only 8GB of RAM (but HBM!).A straight 4096SP GCN 1.2/3 GPU would be a close match-up already, but any other improvements made along the way will potentially give the 390X a fairly healthy launch-day lead.
I think nVidia wanted to keep AMD in the dark as much as possible so that they could not position themselves to take more advantage of this, but AMD decided to hold out, apparently, until May/June (even though they apparently already have some inventory on hand) rather than give nVidia a chance to revise the Titan X before launch.
nVidia blinked, it seems, after it became apparent AMD was just going to wait out the clock with their current inventory.

Unless AMD has achieved considerable increase in perf/w, they are going to have really hard time tuning those 4k shaders to a reasonable frequency without being a 450W card.Not that being a 500W is necessarily a deal breaker for everyone, but in practice cooling a 450W card without causing ear shattering level of noise is very difficult compared to cooling a 250W card.
Let us wait and hope, since AMD really would need to get a break and make some money on this one...

Very true. We know that with HBM there should already be a fairly beefy power savings (~20-30W vs 290X it seems).That doesn't buy them room for 1,280 more SPs, of course, but it should get them a healthy 256 of them. Then, GCN 1.3 vs 1.1 should have power advantages as well. GCN 1.2 vs 1.0 (R9 285 vs R9 280) with 1792 SPs showed a 60W improvement, if we assume GCN 1.1 to GCN 1.3 shows a similar trend the 390X should be pulling only about 15W more than the 290X with the rumored specs without any other improvements.
Of course, the same math says the 290X should be drawing 350W, but that's because it assumes all the power is in the SPs... But I do think it reveals that AMD could possibly do it without drawing much, if any, more power without making any unprecedented improvements.

Yeah, but the question is, How well will the memory survive on top of a 300W GPU?Because the first part in a graphic card to die from high temperatures is the VRAM.

It will be to the side, on a 2.5d interposer, I believe.GPU thermal energy will move through the path of least resistance (technically, to the area with the greatest deltaT, but regulated by the material thermal conductivity coefficient), which should be into the heatsink or water block. I'm not sure, but I'd think the chips could operate in the same temperature range as the GPU, but maybe not. It may be necessary to keep them thermally isolated. Which shouldn't be too difficult, maybe as simple as not using thermal pads at all for the memory and allowing them to passively dissipate heat (or through interposer mounted heatsinks).
It will be interesting to see what they have done to solve the potential issues, that's for sure.

Yes, I agree that AMD would be able to absolutely destroy NVIDIA on the performance front if they designed a 500W GPU and left the PCB and waterblock design to their AIB partners.I would also absolutely love to see what kind of performance a 500W or even a 1kW graphics card would be able to muster; however, since a relatively constant 60fps presented with less than about 100ms of total system latency has been deemed sufficient for a "smooth and responsive" gaming experience, I simply can't imagine such a card ever seeing the light of day.
And while I can understand everyone likes to pretend that they are saving the planet with their <150W GPUs, the argument that such a TDP would be very difficult to cool does not really hold much water IMHO.
If, for instance, the card was designed from the ground up to dissipate its heat load over multiple 200W~300W GPUs, connected via a very-high-speed, N-directional data interconnect bus, the card could easily and (most importantly) quietly be cooled with chilled-watercooling dissipating into a few "quad-fan" radiators. Practically, 4 GM200-size GPUs could be placed back-to-back on the PCB, with each one rendering a quarter of the current frame via shared, high-speed frame buffers (thereby eliminating SLI-induced microstutter and "frame-pacing" lag). Cooling would then be as simple as installing 4 standard gpu-watercooling loops with each loop's radiator only having to dissipate the TDP of a single GPU module.

They did solve that problem with a water-cooling solution. 390X WCE is probably what we'll get.ShieTar - Wednesday, March 18, 2015 - link
Who says they don't allow it? EVGA have already anounced two special models, a superclocked one and one with a watercooling-block:http://eu.evga.com/articles/00918/EVGA-GeForce-GTX...

If by fast you mean June or July. I'm more interested in a 980ti so I don't need a new power supply.ArmedandDangerous - Saturday, March 21, 2015 - link
There won't ever be a 980 Ti if you understand Nvidia's naming schemes. Ti's are for unlocked parts, there's nothing to further unlock on the 980 GM204.
