I need advise, which system to keep...the 3800X2 at 2.65, or the 2xXeon system with HT, at 2.5 each

[superHARD]

sys 1
3800X2 @ 2.65ghz

sys 2
Dual Xeon system (remember these are HT chips)
Each chip is doing 2.5ghz

I mostly unrar, and run quickpar (for fixing messed up DL's)...which system is going to process the most data the fastest?

Ram, Video, etc is not important, all that will be the same in each system.

X2(87.3% sure)

 

[superHARD]

So an X2 with 2 2.65 cores will out process a Xeon system with ~4 2.5 cpu's in it?

The Xeon you have is based on the garbage P4 arch. Athlon64 arch is > P4 any day of the week.

Well it's HT, not true dual-core. If I remember correctly, HT gives about a 20% performance increase over single core.

If it was me, I'd probably keep the X2 3800 for heat and power reasons alone, not to mention you'd be using mainstream (cheaper) parts.

 

[superHARD]

the parts are 100% the same (same ram, hd's, video card, psu, case, etc)

I'm loving my PC-DL Xeon mobo, and not liking my 939 X2 mobo... Maybe I'll sell the xeon system, and sell the 939 mobo, and get a good OC'ing board, and not a great OC'ing board?

i was thinking, keep the system that consumes less electricity, until i saw this last post.

sounds like the Asus (?) PC-DL is a good classic system for you.

Unless the programs you use can use 4 cores then it's not really worth it. I had a dual Xeon 2.0 w/HT on a PC-DL a while back and even in video encoding I didn't see a difference going from 2 to 4 logical cores. Couple that with the fact that the P4 architecture is not so great and you're better off with an OCed X2.

Without a doubt, the X2. It's got a faster clock speed, and it's faster clock-for-clock to begin with. Hyperthreading really only helps when you're multitasking and you've only got 1 CPU. It can make things smoother. But if you've got dual cores already, Hyperthreading won't do a lot for you in most cases. Having Hyperthreading is nowhere near as good as having two physical cores. So if it was 2x dual-core Xeons vs. a single X2, I'd say go with the Xeons. But Hyperthreading honestly doesn't help all that much when your CPU is loaded to begin with.

QFT.

If you're happy with the performance of both machines, sell the one that will bring in more money.
