How much of an upgrade is a P4 2.8 (400mhz FSB) to an AMD Athlon 64 3000+?

[TheVrolok]

I have an opportunity to make this upgrade and I'm wondering if there will be a noticible performance change, also, I"m using a GeForce 6800 and I'm wondering if the AMD would maybe reduce a possible bottleneck created by my older P4 2.8?

I had a P4 2.8 before i got my current rig(see sig) and the difference was night and day.....in terms of speed and setting i could play etc

You're AMD 3000+ at 2.43 is more equivalent to a Pentium 3700-3850 depending on the application. It would destroy a nonoverclocked 2.8 PIV due to the inherent differences in cpu architecture.

Yes, buying that 3000+ will buy you a faster (gaming) system, especially when you overclock it... Up to the level of an AMD Athlon 64 3800+ (2.4GHz) is common... Make sure it's a Venice you get...

For the mobo, get yourself the ASRock 939Dual-SATA2, so you can fit the 6800 AGP for now, and upgrade to PCIe down the road...

Stock by stock the 3000+ isn't that much faster (in fact even slower in certain applications)
but the 3000+ should be more power/heat friendly and the eariler 90nm parts are highly overclockable.

Yeah, right. The bus architecture and speed alone gives you a big difference.

Since you have DDR, FSB400 system, compare to roughly P4 2.8ghz i850, RD800 system. Although that system is still a bit faster than yours. The difference will be noticeable but will not be night and day. If the upgrade is not too costly, you should go for it and later upgrade to a faster PCIe videocard. Also the price difference between 3000+ and 3200+ should be no more than $10.

Theres no such thing as a 2.8/400. Only 2.8/533 or 2.8/800.

It's the called the 3000+ for a reason.
Only using 3D stuff for the measure is not accurate since the AMD FPU performance is always better than Intel since the first Athlon was released.

Actually, there were 2.8/400 northwoods for a while.

Nope, you are incorrect, there is a 2.8 with 400mhz FSB. SL7EY 2.80 GHz 400 MHz 0.13 micron D1 512 KB 478 pin..strait from the Intel website..

In any case, a 3000+ will be faster than the 2.8 400mhz FSB in pretty much any task. If it was a 2.8c I would just overclock it, but older P4's that don't have hyperthreading just don't compare. I can't stand using my P4's with HT turned off, they feel sluggish.

OP if you are refering to performance in games, it probaby won't be much differant, since the video card is the primary limiter, unless you are running at 1024x768 or less, in which case the CPU will start to make more of a differance, and the A64 will be a decent bit faster.
