A ChipHell discussion board consumer has completed what most likely others have already completed in relative obscurity: making an attempt (and succeeding) to flash a Vega 64 BIOS onto a Vega 56 graphics card. The consequence? Properly, apparently the shaders will not unlock (not less than not in accordance to our very personal GPU-Z), however apparently, efficiency improves all the identical. The lesser quantity of shaders on the Vega 56 silicon (3585 Shaders / 224 TMUs / 64 ROPs in contrast to Vega 64’s 4096 / 256 / 64 apparently does not hinder efficiency that a lot. It seems that the improved clockspeeds of Vega 56 after the BIOS flash do greater than sufficient to offset efficiency loss from the lesser quantity of compute sources out there, bumping RX Vega’s clock speeds of 1471 MHz core increase clock and 800 MHz HBM2 memory up to Vega 64’s 1545 MHz core increase clock and 945 MHz HBM2 clock.
Because of this Vega 56 can successfully grow to be a Vega 64 in efficiency (not less than the place 3D Mark Fireplace Strike is anxious), which is not exceptional within the relationship between AMD’s high tier and second-best graphics playing cards. Now naturally, some Vega 56 samples could even be additional overclocked than Vega 64’s inventory clocks, which suggests that there’s the potential for Vega 56 to have even higher efficiency than Vega 64. The BIOS swap ought to enable Vega 56 to entry larger power states than its inventory BIOS permits, which is among the causes it might probably unlock larger core and memory clocks than an overclocked, authentic BIOS Vega 56 would. Nonetheless, the truth that a Vega 56 at Vega 64 clocks and a Vega 64 ship across the similar rating in benchmarks positively does elevate questions on how nicely the additional computing sources of Vega 64 are being put to use.
