![]() ![]() There’s no word yet on ROP counts, but assuming Nvidia followed its historic pattern, the GP100 should have at least 96 ROPS and possibly 128. The total number of streaming processors has increased 17%, as has the number of texture processors. One interesting aspect of Pascal’s design is that Nvidia has again reduced the number of streaming cores in each processing block, or SM and adopted the same ratio that AMD uses, with each compute block containing 64 processors. Note that the dev blog post states that Pascal can include up to 60 SMs, while the variant described below has just 56. The chart below compares Kepler, Maxwell, and Pascal. Pascal’s current GP100 variant adds back all the double-precision floating point that Maxwell was missing - then stuffs some more in, just for good measure. ![]() As we discussed last week, when AMD launched its FirePro S9300 x2, this limited the kinds of workloads where the M40 could excel. The M40 still had an advantage over the K40 in single-precision floating point, but double-precision floating point performance was sharply curtailed. ![]() The old Tesla K40, based on the GK110 GPU, was capable of up to 1.68 TFLOPS/s, while the Tesla M40, which used the Maxwell GM200, could only reach 213 GFLOPs. When Nvidia designed Maxwell, it made the design to remove much of the double-precision floating point capabilities that were baked into its previous Kepler architecture. Pascal’s renewed focus on high-speed compute Today, Nvidia showcased the full HPC version of Pascal and detailed what the card would offer compared with its previous Maxwell and Kepler products. The 28nm node has persisted for far longer than any previous generation, and while both AMD and Nvidia have introduced multiple products on that node, customers have clearly wanted the power efficiency and performance improvements that the 14/16nm node could provide. For the past year, enthusiasts have been chomping at the bit waiting for the next generation of graphics cards to arrive. ![]()
