Just a week ago we wrote that in the case of flashing VGA-UEFI microcode from the flagship Radeon RX Vega 64 to the Radeon RX Vega 56 graphics card, only the nominal frequencies of the GPU core and memory will be increased, and stream processors will remain blocked. However, the other day the monitoring utility GPU-Z received a new version 2.3.0, in which, among other things, full support for the RX Vega graphics card was implemented.
One of the users of the social-news network Reddit with the nickname “Silency”, carrying out various experiments with the firmware of its RX Vega 56, noticed an interesting feature: now the updated GPU-Z 2.3.0 program read 3712 shader processors and 232 texture units. Recall that the original RX Vega 56 involved 3584 SP and 224 TMUs. If you take into account that the index in the name of RX Vega cards means the number of active Compute Units (Vega 56 = 56 compute units). Now, Reddit user Silency managed to turn its Radeon RX Vega 56 into “RX Vega 58”. Other enthusiasts joined in with their “RX Vega 57”, “RX Vega 59” and so on.
Vega 56 = 224 TMUs
Vega 64 = 256 TMUs
256 – 224 = 32
32/(64-56) = 4 then every 4 TMUs equal a +1 to your vega 56
As for the final performance, the so-called “RX Vega 58” after flashing the VGA-BIOS from Radeon RX Vega 64 was faster than the original RX Vega 56 (10% more performance). However, this may be due to the banal increase in frequencies and it remains unclear whether additional blocks are unlocked or it’s just a “bug” in utility.
