  • Completely false. 2.4b transistors would mean it’s less than 1/3 as dense on the same node while being lower performant (so HP cells are not a factor). Why on earth would you even use 7nm when 20nm (and even 28nm) can reach that density easily.

    Use you brain. Just because TPU listed wrong data, doesn’t mean you have to parrot it.

    It has 40% the CU, 50% the CPU, 80% memory bus, nearly 100% front end (geometry, ACE etc), 100% display, video, I/O etc.

    At bare minimum you are looking at 70% transistor count.















  • For comparison, AMD’s 7950X gets 84.06 ns using 4 KB pages over a 1 GB array. AMD’s Phoenix suffers from higher latency and hits 126.7 ns with the same 1 GB test size.

    It’s a bit annoying when he wrote “for comparison” but these are of UNKOWN quality. 84.06ns on what memory configuration? Suffers from 126.7ns on what configuration?

    Previously graph shows bandwidth of less than 100GB/s, and it looks like 85-90GB/s. It could be LPDDR5-5500 or DDR5-5600 of various timings. Again no mention if these are even on the same system. 126ns sounds like JEDEC DDR5-5600B. So if the desktop is using something like DDR5-6000 CL36 then that latency really has nothing to do with Phoenix.
