Prototype of RX Vega based graphics card scores 5721 points in TimeSpy, clocked at 1200 MHz
Note: The score shown in these benchmarks is not indicative of the final product by any means, as is clear from the massive clock speed difference as well as the fact that this could be a different die being incorrectly read as the 687F:C1. A cut down variant is also not out of the question.
Before I go any further, the clock speed of this sample is a mere 1200 MHz. This means you are looking at a number of 9.8 TFLOPs and not the performance Raja Koduri promised. With a single precision compute of 12.5 TeraFLOPs per second on a GPU with 4096 cores, you are looking at a RX Vega 10 graphics card that needs to be clocked at roughly 1526 MHz. Considering the fact that
the already revealed MI25 is passively cooled, it should be able to achieve this mark in due course and even exceed it. The specifications mention the HBM2 stack with 512 GB/s of bandwidth and we already know from the RX Vega Doom demos that the product will have total vRAM of 8 GB. The card will consume 225 Watts of power.
AMD’s troubles with achieving clock speeds the likes of the Geforce GTX 10 series makes me suspect that we are probably going to be looking at an RX Vega that will go, at most, toe to toe with the GTX 1080. Anything else, would be wishful thinking given the evidence given. There is however,
one caveat with all of this theorizing. AMD is releasing multiple variants of Vega, and there is a possibility that this particular benchmark is of a cut down chip that is
meant to go head to head with the GTX 1070. The device ID used in this case is 687F:C1, and while the first 4 digits are the same, the last digit is actually different from the ID we usually catch: 687F:C3.
