Quote:The company announced yesterday that the V100 product line will expand by one when the PCIe version of the the Tesla V100 compute card starts shipping by the end of the year. The card will join a suite of previously-announced products that use Nvidia's proprietary NVLink interconnect.
The PCIe Tesla V100 is just a bit tamer than its brethren, a byproduct of a TDP cut to 250 W from the 300 W figure of the other V100 products. The specifications are about 6.5% lower across the board, suggesting that only the clock rates changed.
...
The bandwidth to the rest of the system is chopped down quite a bit, plummeting from the second-generation NVLink's mind-boggling 300 GB/s to a more pedestrian 32 GB/s. The on-package memory is 16 GB of HBM2 on a similar setup to the NVLink version of V100, offering the same 900 GB/s of bandwidth over a 4096-bit interface.
The PCIe Tesla V100 is arriving roughly at the same time as AMD's Vega Frontier cards, and some comparisons are inevitable despite the difference in architecture. The memory speed, capacity, and the single- and double-precision FLOPS specs aren't terribly far off from one another, though rumors suggest that AMD's cards will require a big chunk of power. The second half of the year should be an interesting time for GPU computing.
Nvidia didn't offer pricing information for the PCIe version of Tesla V100, though you can bet it will be exquisitely expensive. The company says that the cards will be available before the end of the year from Nvidia resellers partners and manufacturers including Hewlett-Packard Enterprise. We are unsure if this means that cards will only be available as a part of new systems or if they'll be selling individually. In any case, stay tuned.
