The Test

To show some contrast in performance, we'll be comparing the $245 Pentium D 820 to Intel's single core price-equivalent CPU, the Pentium 4 630. Clocked at 3.0 GHz, the 630 can be found for around $225 at

We also included AMD's 3000+, because it's around the same in terms of their "Performance Rating". In terms of price though, the 3000+ is impressive. We found it for as low as $146 at,, and ZipZoomFly. So keep in mind when looking at the performance results that the AMD chip is $100 cheaper than either Intel CPU.

Although it doesn't support EM64T or EIST, the P4 530 might be worthy of consideration. It's a low clock speed core already, and 64 bit isn't exactly a worthwhile effort at this point. The 530 should perform pretty much the same as the 630 we're testing, so you can keep that in mind when looking at this review as well. If you like what you see from the 630, but not the price, the 530 is around $175 at and ZipZoomFly.

We usually like to kick off our CPU reviews with some CPU math tests, to give an idea of how things look at the very core of performance. We also throw in a memory bandwidth test, to show how the platforms compare.

As you can see, when it comes to mutlithreaded tasks, the Pentium D trounces both single core chips. We'll have to see what happens in today's real-world programs later on though...

Since they both use the same frontside bus rate, the P-D and P4 score the same in memory bandwidth.
