146 vs 3700

1823 28
I have ordered everything I need for my new system but am completely stuck on what cpu. I was thinking an Oteron 146 but with recent price increases they have gone up to around £160 for lesser CACJEs. For that price I could get a 3700 San Diago core. Which would be better bearing in mind I will want to overclock it as far as I can go?

Thanks

Toss a coin, there's simply no way to answer that without knowing both chips.

Sandiego's are more hit and miss. Opterons are not.

Find 2 systems with the same parts and benchmark an Opteron versus a San Diego at equal clock speeds and tell me what you see. It'd be nice if 2 people with identical systems except the processor would be willing to do this. Clock speed isn't everything.....

The opterons do clock as high as sandiegos and higher...
Example:
Take 100 opty 148's and 100 3700's.
I would guarantee you that the % of higher clocks would belong to the opterons. I bet 50 optys would be stable at 3.0, and 20 sandiegos. Get off your high horse wax, you dont know what you are talking about.

That's not the only difference. Find 2 people with identical systems to test. I've seen it before but can't find the link. The Opterons have relaxed memory controller timings. Very close, but definitely a tad slower. Anyone here have a system similiar to someone else except San Diego versus Opteron willing to do a quick run?

Why don't you just enlighten everyone by showing us where you are getting this information that optys will most likely overclock better. And Sccr64472 is right, from what i've heard in the past, the memory controllers on the 3700+ are slightly better.

Huh? I never said the memory controller was better. I just said that the Opterons have slightly relaxed timings. That will make the benchmarks a tiny bit faster, but it doesn't make it "better." There's always a tradeoff between reliability and performance.

I'm just saying that "better" isn't a good word to use because the Opterons' intended use is server applications and is the reasoning for the timing adjustment. They're not inferior or superior, they've just been adjusted to suit their intended use better. Not arguing with your semantics, I just don't agree with the word "better" in this case, even though it's obvious now that you meant faster.
