Nvidia Titan Z users get double precision computing crippled with CUDA 7 REL The Nvidia GTX Titan Z poses for the camera. For those of you who employ FP64, this could be a serious work-breaker and we would urge such readers to stick to the current version until we have a lock on this possible bug.
#Nvidia gtx titan fp64 update
Where the card usually reads as 1/3 DP, after the update it falls to somewhere around 1/19 DP. However it reports suggest that the new CUDA 7 REL update cripples double precision to a surprising extent (thank you for the tip, Dave Oh) for atleast the GTX Titan Z. The core VRM uses a 7-phase power design, with the memory VRM using a 2-phase design.Double precision is one of the major selling points of the dual GK110 based Geforce GTX Titan Z. The PCB hosts two power connectors and a third set of solder points for an additional 8-pin header, located at the right side of the board. This air is eventually pushed through the vapor chamber cooler, then out the back of the card. Air from the blower fan then pushes air through fins atop the baseplate, dissipating heat and pulling it away from VRAM and the VRM. An aluminum baseplate rests between the PCB and the faceplate, which uses thermal pads to conduct heat into the plate. The card uses a vapor chamber cooler for its thermal solution, coupled with a blower fan and usual PWM control. The disassembly process for the Titan XP is almost exactly the same as what is used to disassemble the GTX 1080. NVIDIA Titan X (Pascal) Tear-Down, PCB, & Coolerīelow are a few photos from our tear-down content: We're not benchmarking that today, though. Titan XP and GP102 host 12 billion total transistors and, despite a focus on FP32, works to introduce a new INT8 deep-learning instruction set.
VRAM on-board is 12GB for the Titan XP, versus 8GB for the GTX 1080.
The TiXP expands cache to 3072KB over the 2048KB on the GTX 1080. The Boost behavior has detected thermal headroom to push the clock higher, and so it increases the operating frequency until a point at which a new limiter is encountered (normally power or voltage).Ĭache size also plays a big role in the Titan XP. Note also that we pushed to nearly 2000MHz in our liquid content without needing to overclock – that's GPU Boost 3.0 in action. Clock-rate natively operates at 1531MHz with the stock cooler and hits 1700MHz or higher during load. GP100 makes use of FP64 cores in a way that the Titan XP does not, and so is more suitable for double-precision tasks than the FP32-focused Titan X card of this generation.Īlso like GP104-400, the Titan XP runs 8 TMUs per SM, totaling 224 texture map units. The GP100 chip used for the Tesla P100 Accelerator is built for simulation and deep learning, which means it's got a completely different implementation of cores. This is why we often remind folks that cores and SMs can't be compared cross-generation, or sometimes even intra-generation. GP102 follows GP104's architecture and splits GPCs into sets of 5SMs, as opposed to the GP100 GPC-SM alignment of 10 simultaneous multiprocessors per GPC. This isn't the biggest Pascal chip out, in terms of total SMs, but it's the biggest in the GeForce line. GP102 hosts a total of 6 GPCs, for 28 SMs and 3584 CUDA cores. We detailed GP100 a few months ago, if interested in learning more about Pascal's intricacies. The only current Pascal chip that's equipped in a flashier fashion than the GP102 is GP100, used for the Tesla P100 Accelerator and not meant for gaming. The Titan XP uses a GP102 GPU under Pascal architecture, the largest Pascal chip presently available on a GeForce-branded card.

Titan XP Hybrid Mod Part 2 - Assembling the Card If you're curious to learn more about the card, our previous Titan XP Hybrid coverage can be found here: Review content will focus on thermal, FPS, and overclocking performance of the GTX Titan X (Pascal) GP102 GPU. The Titan X (Pascal) card is priced at $1200 from nVidia directly. From that perspective, we're reviewing the GTX Titan X (Pascal) for its gaming performance versus the GTX 1080, hopefully providing a better understanding of value at each price-point. We'd generally recommend such a device for production workloads or CUDA-accelerated render/3D work, but that doesn't stop that the card is marketed as a top-of-the-line gaming device with GeForce branding. This content revisits the Titan XP for a review from a gaming standpoint.
#Nvidia gtx titan fp64 drivers
We also ran benchmarks before tearing the card down, albeit on drivers from mid-August, and never did publish a review of the card.
This was done for Sam, the owner who loaned us the Titan XP, and was completed back in August. The Titan X Hybrid mod we hand-crafted for a viewer allowed the card to stretch its boost an additional ~200MHz beyond the spec.
