I read somewhere that the PlayStation's CPU, the R3000 was similar to the Nintendo 64's CPU.
Apparently, the N64 had a R4000 that was clocked higher (hence, more heat).
Is this true?
The Nintendo 64's central processing unit (CPU) is the NEC VR4300.
A cost-reduced derivative of the 64-bit MIPS Technologies R4300i.
Built by NEC on a 0.35 µm process, the VR4300 is a RISC 5-stage scalar in-order execution processor, with integrated floating point unit, internal 24 KB direct-mapped L1 cache (16KB for instructions, 8KB for data).
The 4.6 million transistors CPU is cooled passively by an aluminum heatspreader that makes contact with a steel heat sink above.
The PlayStaton has,
MIPS R3000A-compatible 32-bit RISC chip running at 33.8688 MHz
The chip is manufactured by LSI Logic Corp. with technology licensed from SGI.
Features an operating performance of 30 MIPS, Bus bandwidth of 132 MB/s and a 4 kB Instruction Cache.
