What difference does cache make?

[K404]

Well...to be honest, from what i`ve seen so far.... not much!

Winchester @ 2.4GHz... (superPi, 1M)



San Diego 4000+, stock (2.4) (superPi, 1M)



Frame rates, UT2003

Winchester:86.169479 game defaults, 6600GT, 500/900

San Diego: 87.370895 same same same

Well...a very very quick lot of comparisons, but... that makes the extra cache look very poor value for money. I`ve not tried overclocking the Sandy, but its a CABGE, so I may be tempted.

Any opinions?

Better frame rates and higher benchmarks scores in 01 03 and 05 good for games and video encoding

I believe it does make a difference. Gotta love 2mb

I'm sorry but unfair comparison, you must have the bus overclocked to get that 3200 up to 2.4GHz so in that sense your making up for the shortfall in increased bandwidth

You want to drop the sandy to 10*200 to match the 3200 and run both at 10*200 same settings i.e. RAM timings to make it fair

Good point Firelord, will try it

I agree that its unfair with the fsb and trimmings being differant.

From what i understand 1mb cache is meant to be about the same as a 512k + 200Mhz chip?

This is how AMD do it and i expect therefore that my SD running at 2.66Ghz would be comparable to a venice at 2.86Ghz?

Right, theres some differences now, I apologise for being a dumbass...

San Diego @ 2GHz



Winchester @ 2GHz



UT2003:

Winchester: 65.367813

San Diego: 75.033646

Heh...thats MUCH more like it! SuperPi scores arent massively different, but enough to decide a 1st place from a 2nd.

I`m not gonna say my first post was a complete waste though...it looks like that shows approximate compensation between Winchester and San Diego cores... 240x10=200x12 for performance.

I knew you'd find a difference once you had em at the same speeds

I always find that windows is smoother with a meg of cache and helps with DVD encoding

I can be a right spanner, what can I say ??! Prob not gonna keep the proc though, after the mobo accident, I cant really afford it. At least it was cheaper than usual. Maybe a 3700+ in a bit, or an X2.

10 FPS is a good jump at the same speeds, cant argue with that.

If a CPU has a greater cache doesn't that mean that it will take longer to search as it is deeper in the chip? I remember something about that with the Prescotts compared to the Northys...

Hello mate,

Interesting comparision you have going there. 10fps is a nice gain i think. Makes me with i had bothered to do more comparisions when i went from 3000+ winnie to SD3700+. I would be interested to know how they compared at for exampel both at 10 x 220 = 2.2Ghz & 10x240 etc ...
