Re: Difference between CPUs? (AMD)
There are two types of Sempron. One is no different from a K7 Thoroughbred core socket A proc, the other is a socket 754 chip that shares the on-die memory controller in common with the A64. The socket A chip, being a TBred with 256KB of cache, is slightly slower than the Barton with its 512KB of cache, but it's just about unnoticeable outside of multitasking. The S754 chip offers the latency advantage of the on-die memory controller which accounts for most of K8's IPC over the K7. However, last I checked, S754 chips aren't that much of a saving over getting a low end A64, so it might offer a tad more "future proofing" to go with S939 over a Sempron. There will be a third type of Sempron that is basically the S754 chip with x86-64 enabled in response to Intel enabling it on its Celeron line. |
