Nvidia GTX 1080 Ti / Titan Rumors: GP102 GPU Delivers 13 TFLOPS, Next Titan To Feature 24GB of HBM2 Memory, 720 GB/s of bandwidth
Last month, Nvidia launched the GTX 1080 and GTX 1070, both based on their Pascal GP104 GPU. Nvidia claims both cards are faster than the GTX Titan X, but that doesn’t mean they are the successors to previous generation flagships. Instead, the GTX 1080 Ti and the next Titan X could be the ones aimed at the enthusiast market. The upcoming cards are expected to be powered by the GP102 GPU, which is likely to feature a full FP32 unit series.
The GP102 GPU will probably include 3840 CUDA cores, but what’s more interesting is that it is rumored to deliver performance equivalent to the GTX 1080 2xSLI, which means the next Titan X should be 50% faster than a single GTX 1080. Believing this, the GP102 GPU must be capable of delivering 13 TFLOPS of compute performance provided it is clocked at 1733 MHz, the same boost clock as the GTX 1080.
However, many of you may be wondering why the next gen enthusiast cards won’t implement the flagship GP100 GPU. Well the fastest Pascal chip has its own limitations, for instance, it probably lacks ROPs (Render Output Unit) and TMUs (Texture Management Unit), making it incapable to be used for gaming applications.
Further, the GP100 has 1792 FP64 CUDA cores which are practically of no use in the desktop applications. So the FP64 die area size would be just an extra occupying space on silicon. With GP102 GPU, Nvidia won’t only be able to reduce costs and circuitry complexity but the chip is likely to achieve better yields, as well.
The Pascal based enthusiast cards however won’t feature the same GP102 variant. The GTX 1080 Ti could employ a cut down version of GP102 chip with 3584 CUDA cores while the next Titan card will probably feature a ‘full fat’ GP102 with 3840 CUDA cores.
In terms of the memory, the 1080 Ti is expected to come with 12GB of GDDR5X modules across a 384 bits bus, delivering a total bandwidth of 576 GB/s. On the other hand, the Titan card could have 24GB of memory on board with HBM2 modules built by Samsung, achieving 720 GB/s of bandwidth – though it can go beyond 850 GB/s thanks to color compression and other adjustments made by Nvidia.
None of the above specs are official yet, but if accurate, the GTX 1080 Ti and Titan are going to be real monsters. Do you think AMD Vega based cards can give some serious competition to these graphics monsters from Nvidia? Let us now in the comments section below.
