Pentium 4 6XX Sequence and New EE P4s Launched

Mojo-Dog writes "Today Intel took the wraps off their new Pentium 4 Processors with EM64T extensions for 64-bit computing. The Pentium 4 6XX Sequence and Pentium 4 3.73GHz are based on Prescott 2M cores with a full 2MB of on-chip L2 cache as well. HotHardware.com has a full review with benchmarks posted of these new P4s, many of which also offer Intel's SpeedStep technology for power savings and improved thermals, which has been available in Pentium Mobile CPUs for some time now."

  2. Re:Nothing really about 64 bit performance by Anonymous Coward · · Score: -1, Troll

    When going from 16 to 32 bits, the performance more than doubled because virtually nothing was done in 16 bits even then. However, pretty much nothing requires more than 32 bits now, besides programs with large datasets. Since most things now do not require more than 32 bits (and likely never will), moving to 64 bits just means more cache misses and page faults, both of which reduce performance.

    In other words, do not expect performance to improve for any 64-bit app aside from those that require multiple GB of memory.

  3. Emulated 64 bit processing by payr0k · · Score: -1, Troll

    come on. If you look into it, these are 64bit extensions not a 64bit processor core. They're trying to doop the masses. They're emulating 64bit. It's a waste of money.
