AMD RX Vega 56 does not feature full Vega 10 and the die is a cut down version of the AMD RX Vega 64. People thought that the AMD RX Vega 56 was somehow locked and that playing around with the BIOS would allow them to unlock extra cores and get the performance of the AMD RX Vega 64. But that is not the case But there is more to the story.
On the brighter side, the BIOS mod does allow you to achieve higher clock speeds which means better performance as compared to the default BIOS. The RX Vega 64 BIOS has a boost clock of 1545 MHz, while the AMD RX Vega 56 has a boost clock of 1471 MHz. So with the BIOS mod you are getting the clock speeds of the Vega 64 on the AMD RX Vega 56.
The BIOS mod also allows you to increase the HBM2 clock from 800 MHz to 945 MHz. By doing all this, the end result is that the modded AMD RX Vega 56 is only 2% slower than the big brother 64 and I think that is something people can live with. You can check out the benchmark of the modded card below:
Overclocking results of the card without the BIOS mod have shown some impressive numbers and with this BIOS mod out there, the AMD RX Vega 56 could become more popular than the bigger brother. There have been a couple of issues with Vega pricing and I doubt you will be able to get the Vega 64 at MSRP. Most of the GPUs are sold out even at higher prices.
Let us know what you think about the AMD RX Vega 56 and whether or not you are interested in buying one of these GPUs.
