Celeron D will run fine and isn't a slow processor. In fact, Intel fixed lag issues with the Celeron D by adding more cache than the usual 128k that Celeron's previosly received in older generations. In addition to the new instructions its received, it will perform just as well as a Northwood and even some Prescott CPU's of the Intel generation CPU sets. Because of the new architecture, you can match performances of an Intel Extreme Edition if you decide to OC the Celeron D over 3 GHz.
Personally, a Celeron D would be the better move since Pentium 4's are still overpriced and do not offer that much better performance over a Celeron D processor.
What socket are you talking about, specifically?
Not really, Celeron D's are built on the Prescott revision of the netburst core. Having an extremely long pipeline with 31 stages will make branch prediction errors, and cache misses extremely costly. The typcial Celeron D has only 256kb of L2 cache, and 12+16kb of L1, That is less L1 than the 64+64kb of L1 of the Sempron, which have the same amount of L2 cache.
For equivalent P4 E (prescott) and A64, the P4 typically needs much larger cache to come close to A64 in performance. That's why single cored P4 typically have 1-2MB of L2 cache, while A64 has 512kb - 1MB L2; and A64 will still suffer less due to cache misses because of the much shorter 12/17 stage split pipeline.
The Prescott Celerons (Cel. Ds) compared to the Sempron, typically will fare worse than the comparison between P4 and A64, because of the discrepency in cache size. The L2 of the Celeron D needs to be much larger, at least 512kb, to have a chance to even catching similarly rated Semprons in performance. The older Northwood based Celerons were actually much better, with a 20 stage pipeline, somewhat more efficient IPC, and lower heat output as well. Celeron D's are probably the worst performing chips on the market with exception of the odd Via integrated chips or the extremely low power Transmeta chips and such.
don't feed on bullcrap, bench mark a Celeron D with a Northwood Celeron. You can already tell by installing a version of Warcraft III on both systems with similar specs and you will figure it out for yourself. ofcourse a Sempron would be a good choice, but he's asking whether a P4 vs a Celeron D would make the difference. you are clearly discriminatory towards Intel.
