The original GTX Titan GPU had a unique characteristic that made it popular for more than just gaming, it had support for Double Precision, FP64, compute, allowing people to access some huge amounts of compute performance at a price that is much lower than Nvidia's Tesla or Quadro GPUs. The core VRM uses a 7-phase power design, with the memory VRM using a 2-phase design.Nvidia Pascal Titan X will not feature faster FP64 or FP16 performance 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. NVIDIA Titan X (Pascal) GP102 Architecture NVIDIA Titan X (Pascal) Specs NVIDIA Pascal vs. 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. 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.
