I don't have a link right now but I have the specs well saved on my PC
PSP CPU Core:
- MIPS R4000 32-Bit Core
- 128 Bit Bus
- 1~333 MHz @ 1.2V
- 8 MB (eDRAM)
- Bus Bandwidth: 2,6 GB/sec
- I-Cache / D-Cache
- FPU, VFPU (Vector Unit): @ 2,6 GFlops
- 3D-CG Extended Instructions
PSP Media Engine:
- MIPS R4000 32-Bit Core
- 128 Bit Bus
- 1~333 MHz @ 1.2V
- Sub Memory: 2MB (eDRAM) @ 2,5 GB/sec
- I-Cache / D-Cache
- 90nm Cmos
PSP Graphics Core 1:
- 3D Curved Surface + 3D Polygon
- Compressed Texture
- Hardware Clipping, Morphing, Bone(Fighissimo!
- Hardware Tessellator
- Bezier, B-Spline(NURBS)
- reduce memory footprint & bus traffic
PSP Graphics Core 2:
- Rendering Engine + Surface Engine
- 256bit Bus, 1-166 MHz @1.2V
- VRAM :2MB (eDRAM)
- Bus Bandwidth: 5.3GB/sec
- Pixel Fill Rate :664 M pixels/sec
- max. 33 M Polygon/Sec (T&L)
- 24bit Full Color: RGBA
Ad you can read the PSP graphic chip has 664 Megapixel/s fill rate at 166MHZ,the maximum frequency,against the 1,2 Gigapixel/s fill rate of PS2 in single texturing.
It can rasterize 33 million polygons peak,the same figure for GS is 75 million.
The embedded ram has a really small bandwidth compared to the 48GB/s of the GS.
The CPU has 2.6 Gigaflops @ 333MHz against 6,2Gigaflops of the Emotion Engine.
So on the paper it's really not a PS2,more a Dreamcast 1.5.
Anyway a lot of really impressive games are coming so who cares
