In the meantime, a 3DMark Time Spy benchmark result popped up. It shows the performance of the "687F:C1" video card on a system with the AMD Ryzen 7 1800X processor. This card is believed to be one of the first Vega parts, the tested sample was running at only 1200MHz and featured 8GB (presumably HBM2) memory clocked at 700MHz.
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.The early sample of the Vega card scored 5950 points in the Time Spy test, with a graphics score of 5721 points, which puts it roughly in the same territory as the NVIDIA GeForce GTX 1070. This could potentially be a cut-down version or an early sample with a lower clockspeed, we just don't know.
