Both the 360 and PS3’s CPUs are heavily stripped down compared to what most of us are probably using on our desktop computers to view this article. Both consoles are labeled as 3.2GHZ, but they don’t offer performance comparable to that of a typical Athlon 64 3200+ or better than even an Athlon XP 2800+ CPU. The CPUs inside the Xbox 360 and PS3 are “In-Order Execution” CPUs with narrow execution cores, whereas what we use on our computers are classified as “Out-of-Order Execution” CPUs with wider execution cores.
The reason they can sell for so cheap is because they are not as robust or complex as what we have inside our computers. The execution theme in both the 360 and PS3’s CPUs is similar to that of what you would see in the original Intel Pentium Processor. (Not referring to the Pentium 2 3 or 4, but the original) This is because they’ve stripped out hardware designed to optimize the scheduling of instructions at runtime. As a result, neither the 360 nor PS3’s CPU contain an instruction window. Instead, instructions pass through the processor in the order in which they were fetched; hence both are “In-Order Execution” CPUs.
Marketing talk from Microsoft and Sony: Thanks to these multi-core processors developers will be able to multi-thread their games and get significant performance improvements and achieve Artificial Intelligence in games that people previously thought impossible for a videogame. It’ll be as if you’re playing with another living breathing human being.
