I'm really trying to figure out what the main difference is here besides voltage?

Cooling Device - Heatsink and Fan


AMD Athlon 64 4000+ ClawHammer 2000MHz HT Socket 939 Processor

Is there any major difference between these two proc's? If it makes any difference I plan to partner either of them with an ASUS A8N32-SLI Deluxe. I decided to move this to another thread since I decided on a single core still plan on getting the X1800XT 256 or 512 depending on which I can find.

Clawhammer is a 130nm core; San Diego is a 90nm core. The San Diego will use less power and produce less heat - it'll supposedly also overclock better. The only other difference I see is the addition of the SSE3 instruction set, but I can't explain that.

:? Could someone explain SSE to me, since it comes on practically every modern CPU?

San diego hands down cooler, faster(better cache access time), and it's usually cheaper 2 toi 5 bucks on newegg and zzf also if you can wait a month for the price to go down even more.

Wait, I thought AMD already slashed prices on single-cores. Apparently it only applied to Venice cores...why didn't the San Diego procs get the discount as well?

Cache latency is the same on both.
June 20, 2006 12:25:49 AM

Nah i heard that on 90nm a64's the cache time went down alitlle by atleast 5 nano seconds if data could tell me where to find that article it would be good.
June 20, 2006 12:46:39 AM

Access time in cycles is still the same.
June 20, 2006 12:54:57 AM

Can you give me a link showing that?
June 20, 2006 12:57:48 AM

Just hit up google.

Ok thanks.

Action man is right.
June 20, 2006 1:03:46 AM

I know i saw i got confused with something else.
June 20, 2006 1:57:21 AM

3700+ San Diego core is the same as the 4000+, FX 55 and FX57 ... room to grow!

OMG you got downvoted because you said I was right. Damn you AMD fanboys are sh!tty.

What i did'nt downvote him infact i'll upvote him if you want.

So the San Diego runs cooler that's good to know as it is the cheaper proc by a good amount gives me the extra incentive to pick up a faster smaller hd for my primary.

Ya, that'd be cool.

What's this? A warning to buy a 1 mb cache chip why I still can? I want more cache, more power, more whatever.
