Minisforum have another mini PC on the market, the UM780 XTX, and this time I wanted to see how the iGPU compares to one of the most popular budget gaming gr...
8 TFLOPS on RDNA 3 is comparable to 4 TFLOPS on RDNA 2 (PS5).
The PS5 uses 36 compute units. The 780M has 12.
The PS5 has 450GB/s memory bandwidth. The 780M has around 100.
The 780M runs at significantly lower power and shares the memory bandwidth with the CPU, but even ignoring that it’s like 3-4x worse than a PS5.
it does not work like that… 8tflop rdna3 is becaue they count the fpu perf like it is done on ampere/ada ie both the int and fpu alu can to fp while older u arch had fixed alu for int and fp.
And there is a problem with the rdna3 where this function is not working correctly so we only get the additional 30% fpu perf from the additional fp alu units.
and like u sait the memory is holding back the apus but it will still not perform like an 8Tflop gpu.
The 780m has 8 teraflops but is limited by memory bandwidth
