gergroy said: Wait, I thought you knew hardware really well? Original xbox versus ps2 was much bigger difference in terms of power than 50%. I mean, the xbox cpu was more than twice that of the ps2, double the ram, better gpu, etc. xbox was more like 2 to 3 times more powerful. Go back and look at the specs. It was easily much more clear cut than x1 vs ps4. |
No.
CPU Winner: PS2
32-bits Pentium III CPU @ 733Mhz vs 128-bits Custom with two specialized VPUs @ 300MHz
-Data bus, cache memory as well as all registers are 128 bits on the PS2 CPU while the XBox CPU is 32 bits.
-It has a max. performance of 6.2GFLOPS while the XBox CPU can only do a bit over 3 GFLOPS.
-It incorporates two 64-bit integer units (IU) with a 128-bit SIMD multi-media command unit, two independent floating point vector calculation units (VU0, VU1), an MPEG 2 decoder circuit (Image Processing Unit/IPU) and high performance DMA controllers. Yes, this is all on the emotion engine itself.
* The PS2 is so powerful that it have a GPU just to video output... no GPU at all *
GPU & VRAM Winner: Xbox
nVidia GPU @ 250Mhz vs Custom @ 150Mhz
-The XBox GPU can do 125 million polygons (according to Microsoft) while the PS2 GS can only do 75million polygons
-The XBox GPU has a max. resolution of 1920x1080 and the PS2 GS can do 1280x1024, the rest of the graphics chip will be comparable to NV-20 chip.
* PS2 GPU is weak and only used to framebuffer and video output... Xbox have a better GPU here with more modern effects *
RAM Winner: Tie
32MB Direct RDRAM 2 channels at 800MHz (3.2GB/s) vs 64MB DDR SDRAM 2 channels at 200 MHz (6.4GB/s)
* There are some tricks here... PS2 have the VRAM @ 48GB/s for framebuffer (yeah like 360 eDRAM) and the PS2 CPU had a MPEG2 decoder so it really compress/decompress images far way fast than Xbox... now it is not me but developers said the PS2's memory system works better than the Xbox *
Overall Winner: Xbox
The PS2 CPU beat both Xbox's CPU or GPU when compared separately but when you combine the them the Xbox have a good advantage in raw power between 20% and 30%.
Xbox is more powerful but it is not like you think... PS2 CPU was a 128-bits monster... it alone hold the graphics on PS2 and you can see that on Gran Turismo 4, God of War II, Shadown of Colossus, etc... while Xbox have the top graphics the difference was not big like this new generation.
BTW Gamecube was as powerful or even slightly more than Xbox
