Integrated GPUs are often low-end affairs. Even when graphics performance matters, a combination of cost, die space, memory bandwidth, and power constraints prevent iGPUs’ performance from re…
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.
