Then there is the factor that Intel and AMD are skirting the issues and keeping the hardware in 32 bit with multi-core processors. While you can have a 32 bit processor and 64 bit OS, you can still see bottlenecks on the system because of it." No, you can't. 64-bit instructions (e.g. amd64) can only run on a CPU with a compatible ISA. (I'm not sure what that has to do with multi-core--many of Intel's dual- and quad-core CPUs are 64-bit, including the one I'm typing from.) Also, the 128-bit-Windows article is a hoax. And a 128-bit CPU wouldn't be inherently faster, since instructions and memory addresses would now be twice as big (requiring twice the L1 and L2 cache). Unless you plan to buy more than 2^64 bytes of memory, you wouldn't see an advantage from having "more exits." I know I'm wasting my time pointing out that someone is wrong on the Internet, but maybe you should blog about a topic you know something about. “Of course, 128 bit processing is a ways away.
