Isn't it a power budget and heat dissipation thing? For example the Xbox Series X and Playstation 5 GPUs have pretty similar architectures, but the PS5 has fewer compute units at a higher frequency. Surely Microsoft would have loved to clock theirs as high as Sony.
PS5: 10.28 Teraflops, 36 Compute Units running at 2.23GHz (variable frequency)
XSX: 12.11 Teraflops, 52 Compute Units running at 1.825GHz (fixed)

Less power used on memory bandwidth, means more is available for other things. This card is not so much "bad at mining" and more like trying to design for a different niche that might be underserved by all the "good at mining" GPU's.
- torginus 5y agoI love how Mark Cerny managed to spin Sony having to raise the clock frequency of the PS5 GPU to compete with a the XSX's TFlop specs as an advantage. GPUs tend to be memory-bandwidth bound - if you play around with raising the clock frequency by 10% from stock on most GPUs, you won't get 10% more fps, likewise if you drop the frequency by 10%, you won't lose 10% fps. But with the power consumption scaling with the square of the frequency, the difference in power draw can be absolutely significant. That's the reason many people (me among them) chose to underclock their 5700XTs
