Internal computing power
The PlayStation2's 128-bit CPU, affectionately dubbed the "Emotion Engine," is integrated on a single chip made by a joint venture company established between Sony and Toshiba.
For memory, the CPU uses Direct Rambus DRAM in two channels to achieve a 3.2GB/second bus bandwidth, which Sony claims is four times the performance of PCs built on PC-100 architecture.
CPU -- 128-bit "Emotion Engine"
System clock frequency -- 294.912 MHz
Cache memory -- Instruction: 16KB, Data: 8KB + 16KB (ScrP)
Main memory -- Direct Rambus (direct RDRAM)
Memory size -- 32MB
Memory bus bandwidth -- 3.2GB per second
Co-processor -- FPU (Floating Point Unit)

Imaging and graphics
The PlayStation 2's graphic synthesizer incorporates a powerful parallel rendering engine with a 2,560-bit wide data bus. It achieves high pixel fill rates and drawing performance by using the embedded DRAM process technology SCE created for use in advanced graphics.
Sony says its new GS rendering processor was enhanced to generate image data that supports NTSC/PAL television. The resulting screen image is comparable to movie-quality 3D graphics in real time.
