Comparing my A64 3000+?

post #1 of 9
Thread Starter 
ok so im getting a good $150 bucks tommorrow.. and due to me getting a faster hard drive for christmas the only thing left to get is a new motherboard. I want a new cpu too but i cant afford both so, frankly i need a motherboard thats capable of overclocking. ok so i found one, thats not the question. the question is, due to my CPU having 512kb L2 cache, if i got it to 2.6 Ghz then what CPU out there would it be compared to in gaming? would the L2 even matter that much anymore?

Rep+ for helpers, thanks

Well, its a helper in games. Think about it. I have a 800mhz overclock. The stock is 1800. Thats almost 50% more!

Edit: It would be compared to a super awesome overclocked processor. It would be compared to me! War of the 3000+ overclock is on lol

L2 cache does help, but not that much - pretend that its 200 MHz slower and you should be ok

L2 Cache does not help that much. I beleive around 2-5% depending on application. Search for a review that benchmarks a X2 3600+ (2x256MB) vs X2 3800 (2x512MB). There's also ones that compare the 4200 (2x512MB) vs the 4400 (2x1GB). Clock speed has a much great impact. In fact, the larger the cache... the less probability of a high overclock, all things equal. More cache means more place for failure.

X2 3600+ (2x256MB) vs X2 3800 (2x512MB).

4200 (2x512MB) vs the 4400 (2x1GB).

Woah judging by those benchies it looks as thought less cache seems better in gaming.. im in a world of confusion from here on out.

as of right now the l2 cache on AMD's don't really matter. i quote from the hardforums

Quote:
The performance difference between 512kb and 1mb L2 cache has been debated long and hard here for many, many months and the bottom line is that there is little performance difference in day to day functions between the 2. The difference won't be noticable at all. The reason for that is that AMD's memory controllers are on the cpu die whereas Intel's are off-die and require a pathway from the mem controller to the cpu, thus making the lines of communication longer and thus slower. This is overcome by larger L2 cache sizes. In intel systems there is a noticeable difference between 512kb and 1 mb of L2 cache. Some intel systems use up to 2 mb of L2 cache and Conroe has a 4 mb L2 cache. In Intel systems its necessary to have more L2 cache because of their architecture. On the other hand, AMD's on die mem controller speeds things up very dramatically thereby allowing for a smaller L2 cache which is more efficient. AMD knows this and that is why you see almost all their new cpu's with only 512kb of L2 cache.
If you want to waste your money on a 1mb L2 cache you are certainly free to do so, but don't be fooled into thinking you're going to see a greater performance from it. My 3400+ Venice with 512kb of L2 cache easily outpaces both my 3400+ and 3700+ Clawhammers which have 1 mb of L2 cache. Same goes for the newer cpu's as well - otherwise AMD wouldn't be producing so many new cpu's with only 512kb of L2 cache. They know 512kb is quite sufficient due to their architecture.
pretty much since AMD has an IMC you don't need as much cache.

Thank you, thats very good to know... REP+!

You can probably upgrade your whole system over to s939 dual-core which will greatly improve your gaming performance. If you sell your existing system as a barebones - chip and mobo, you could use that money plus the $150 to get a new mobo and the Opty 165.

AMD Opty 165

Biostar TForce 6100

That totals less than $200 and you can keep your existing RAM to toss in. You will get the added benefit of having dual-channel RAM, dual-core, 1mb L2 cache per core, and the great OCing potential of the Opty. Plus the board will allow you to get another vid card later (possibly via Santa for Xmas?) for SLI. I think this may be a better route than upgrading older s754 stuff.
