Spotted: AMD Vega card with 1600MHz clockspeed and 16GB HBM2

Another AMD Vega-based card popped up on the CompuBench database. This model may be the fastest seen to date it has a clockspeed of 1600MHz but it's unknown whether that's a frequency limit or the actual boost clock. The card has a whopping 16GB HBM2 so it's also unknown whether this is a Radeon RX Vega for the consumer market or a Radeon Pro or Radeon Instinct for the professional market. A card with 16GB HBM2 seems like too much for the consumer market.

Either way, the most interesting part of this leak is maximum clock frequency (CL_DEVICE_MAX_CLOCK_FREQUENCY). For comparison, Radeon RX 480 in CompuBench database has the same entry with 1266 MHz and Radeon RX 580 up to 1430 MHz (because most cards are overclocked). This could be an indicator that Vega has 1600 MHz maximum GPU clock. Whether that’s a frequency limit or actual boost clock, we don’t know yet.

Lastly, we have a confirmation that this particular ID has 64 Compute Units enabled. If AMD kept the same principle for GFX9 architecture (64 cores per cluster), then we should expect 4096 Stream Processors (64*64).
