The document discusses the three-core IBM PowerPC processor clocked to 3.5GHz or more, memory complement of 256MB or more, and 500MHz graphics chip from ATI with 10MB of embedded SDRAM already detailed in an alleged schematic for the console that appeared on the Web last April.
Apparently, the CPU will also feature anti-piracy and anti-hacking security technology on the die, along with 1MB of shared L2 cache - up from the schematic’s claim that there would be 512KB of L2 - and 64KB of L1 cache per core split 50:50 for instructions and data. Each core is enabled for simultaneous multi-threading - the ability to convince the host OS it’s two cores rather than one. In other words, the OS - derived, says the document, from Windows NT - sees six logical cores rather than three physical ones.
Each core is said to be able to issue two instructions per clock, which is fewer than the PowerPC 970/G5’s five. The document also mentions “128 vector (VMX) registers”, when the G5, for example, has a single register file containing space for 32 architected registers and 48 renameable registers 128-bit vector instructions.
the specification are good. but… why doesn’t it support xbox 1 game?
