regardless, this is the biggest slowdown for most people using PCSX2, emulating the PS2's CPU aka Emotion Engine (EE).

yes we are looking at a raw 3.6 GFLOPS vs 6.2 GFLOPS but GFLOPS isn't everything when analyzing CPUs, if comparing to the Xbox's 3 GFLOPS is any indicator. rendering at the lower resolution takes a huge load off the PSP and allows it to catch up to the PS2, at least as far as the GPU is concerned because resolution is a job for the GPU.Īs for the CPU, its complicated. PSP only renders 480 x 272 pixels whereas the PS2 renders up to 640 x 480, which is twice the pixel count.

some of this is because of the resolution difference. anyway even if this was true, in practice PS2 games don't look or run twice as good as PSP games (the God of War games are a great example). this wouldn't be too surprising as the gap is actually much worse for a PS3 vs PS Vita scenario but thats a story for another time. So specs indicate that the PS2 has twice the power in certain areas while the PSP is competitive in other areas. and lets be honest, since most of these numbers come from Sony/Microsoft they should be taken with a grain of salt. this would include clock speeds since their respective processors use different architectures, and theoretical numbers such as max polygon counts can vary depending on the method used to ascertain those numbers. (still adding/understanding the specs to ensure accuracy of my statements)įirst disclaimer would be that most of the numbers are not directly comparable. Screen - 640 x 480 (some games run as low as 512 x 448)Īdding Xbox for good measure since it was often considered to be more powerful than the PS2 GPU - 147 MHz, 2.4 GPixels/s, 66 MPolys/s RAM - 32 MB (64 MB for later models) (8 MB allocated for the OS), 2.6 GB/s GPU - 166 MHz, 664 MPixels/s, 33 MPolys/s 'PSP is much weaker than the PS2 and therefore easier to emulate!' Its no secret PPSSPP runs very well and emulates very well while PCSX2 on the other hand though emulates pretty well in recent versions still runs like total ass for a lot of people.Ĭommon statements and ideas with counter arguments and detailed explanations: Lets expand our minds and bust some myths
