NVIDIA and Micron have definitely pushed the envelope with GDDR5X, so given the additional complexities of clamshell mode, it’s not unreasonable to speculate that a 12GB card is for technical reasons along these lines. Or to take it one step further, the Tesla P40, which doesn’t get GDDR5X at all and only has GDDR5. In any case, this compares starkly to the Quadro P6000, which does get 24GB of VRAM, but with its GDDR5X underclocked to 9Gbps. Granted, 12Gbps is coming, but I think Micron would be announcing that and NVIDIA would just run with 12Gbps. It’s telling on the memory bandwidth front that NVIDIA has overclocked the Titan Xp’s memory just a bit 11.4Gbps, even though partner Micron’s GDDR5X tops out at 11Gbps. The other theory is that NVIDIA can’t have it all – they can’t both have super-fast GDDR5X, and 24GB of it in clamshell mode at the same time. However Titan X (Maxwell) was very popular in the previous generation, and it may be that it did a little too well compared to the Tesla, and NVIDA is concerned that there will be a repeat performance here even though they’ve done a much greater level of feature separation via the differences in the GP100 and GP102 GPUs.

Typically this is done via their respective driver sets and what features these cards offer (Tesla not being rigged for workstations, for example).
TITAN X VS 1080 FP64 PROFESSIONAL
The first is that this is a market reason: NVIDIA needs to enforce better market segmentation between the prosumer Titan and the professional Tesla.
I have a couple of ideas on why this is, though it’s all speculation. This is an interesting departure from the norm for the company. However with the Titan Xp, NVIDIA is still only offering 12GB of VRAM, while the otherwise equivalent Quadro P6000 gets 24GB. For the original Titan, this was 6GB, and 12GB for the Titan X (Maxwell).
TITAN X VS 1080 FP64 FULL
In the previous generations, Titan cards have offered the full memory capacity for their associated GPU, equivalent to NVIDIA’s Tesla and Quadro cards. However before we get off of the specifications entirely, there’s one aspect of the new Titan Xp that surprises me: the memory capacity. Simply put, if you’re a regular NVIDIA high-end customer, then NVIDIA has made it very easy to pull out your GTX 780Ti/980Ti/Titan and replace it with the new Titan Xp. The Titan Xp is still a 250W card, and it’s still designed like the last Titan X, clad in black with NVIDIA’s current-generation heatsink and shroud design. Or to compare it the last-generation flagship GTX Titan X (Maxwell), from flagship-to-flagship NVIDIA has improved GPU performance by 84%, ROP throughput by 47%, and memory bandwidth by 63%.Īs for power and other design considerations, this hasn’t changed. Otherwise on the GPU performance front, we’re looking at 7% more shader/texture/geometry throughput and 9% more ROP throughput. However reflecting how NVIDIA opted to hobble the GTX 1080 Ti just a little bit to leave room for the inevitable Titan, NVIDIA’s prosumer card gets a bit more memory and a bit more memory bandwidth, thanks to the re-enabling of the full 384-bit memory bus.īringing back the last 32-bit memory channel and its associated GDDR5X chip gives the Titan Xp a total of 547.2GB/sec of memory bandwidth, 13% more than its lower-tier sibling. What does a Titan get you over a Ti for this generation? Okay, it gets you about the same thing: the last 2 SMs are unlocked, and the memory clockspeed has seen a very small bump. Perhaps more meaningful is to compare the Titan Xp to its only real competition on the market, the GTX 1080 Ti. The last 2 SMs have been enabled, and both the GPU and memory clockspeeds have seen a minor bump as well. Relative to the previous (and now discontinued) Titan, things are pretty straightforward. Instead what we have is simply a fully-enabled GP102 GPU coming to an NVIDIA prosumer card, making it the most powerful video card NVIDIA offers.
There’s nothing new to talk about as far as the design goes, the market positioning, etc. And sure enough, with the recent launch of the GeForce GTX 1080 Ti – which effectively put the original Titan X Pascal out to pasture – NVIDIA is back again to launch their full-fledged Titan for this generation: the NVIDIA Titan Xp.Īs a sort of mid-cycle replacement for the original NVIDIA Titan X (Pascal), this is a bit more of a low-key launch for the company. If the company starts things off with a cut-down Titan, as they did with the Kepler and Pascal generations, then a full-fledged Titan is sure to follow. If you’ve followed NVIDIA’s video card launches over the last few years, then there’s a pretty clear pattern to the company’s release schedule.
