Xeon vs. Pentium 4

[Ace No-Money]

Other than maybe having more Cache, why are Xeons considered faster than P4's???

Prove it!

Xeons are dual processors, some of the best Xeons run dual 3.6ghz cpu's. That means they get work done at a 7.2ghz rate. Plus they have HT and are 90nm.

when you have dual processors, i dont think the performance is doubled, and you actually loose performance unless you have sufficient ram

at the moment, if you have 2 processors, one would work on one program, and the other on anouther program, or background tasks, as windows xp doesnt suport dual processors working on the same task.

Im pretty positive they work like raid0. They can work togather, witch would get work done at 7.2ghz speeds.

 

[waynejkruse10]

are you sure? there has to be some sort of overheads? if you did benchmarking it cirtainly wouldnt be double for the dual processor system.

Technically a dual CPU setup will only run as fast as the CPU speed. But if you are using both with no specific affinity assigned to a CPU they will work max 50% load each.The computer does not run "faster" but rather more efficent. but if you use a program that supports SMP (Symmetric MultiProcessing) ie: like 3-d and CAD software and audio/video editing progs, and any other professional software, then you will reap the benifits of a dual cpu setup.

yeah

can xeon be a single processor tho
look at alienware ALX it looks like it has a single xeon 3.4ghz processor

well the benchmarks that I've seen, the p4's can beat the Xeon's, especially in like video benchmarks.

And when 2 Xeons work together, only one is used until it needs the other, it doesnt work like raid 0
