The Test

We've already covered the architecture behind Intel's Core 2 processors extensively in the past, leaving the only unanswered questions centered around final performance. Today we're here to answer these questions, and we'll focus exclusively on performance. If you want to read more about Intel's Core architecture, please look back at the following articles:

Intel Core versus AMD K8 architecture

Spring IDF 2006: Introducing Intels new Core Processors

Because AMD is killing off its 1MB L2 Athlon 64 X2 parts, we've only included 512KB X2s in this review. The Athlon 64 FX-62 features a 1MB L2 per core and is obviously still included.

CPU: AMD Athlon 64 FX-62 (2.8GHz/1MBx2)
AMD Athlon 64 X2 5000+ (2.6GHz/512KBx2)
AMD Athlon 64 X2 4600+ (2.4GHz/512KBx2)
AMD Athlon 64 X2 4200+ (2.2GHz/512KBx2)
AMD Athlon 64 X2 3800+ (2.0GHz/512KBx2)

    And what about noise Core 2 Duo fan(decibels)? Reply

    Hi,
    Acc. to Toms hardware, for EIST to work, setting in Control panel has to be changed from "desktop" to "portable/laptop".AT guys, was this done? If not, how about putting it in the "Power consumed" graphs?(acc. to Tom(if i rem. right), least power in this mode is about 25watts by core 2 duo!!!).Also anyone knowledgeable, is this setting available in Linux?
    Also, how about putting XP X2 3800+ EE in the encoding benchmarks (along with core 2 duo 6300)?
    Thanks
    Ed
    PS.Price and power consumed when idle are v. imp. to me.

    Unless I missed it what are temps like on these.

    What the heck is a "composite score"...? What are the units? How about giving us rendering times (you know, minutes, seconds) and render settings, so the numbers actually mean something...? Reply

    Where's a good 64bit comparison on Linux and a LAMP stack run at 64bit? There hasn't been a serious linux server benchmark posted. Reply

    I'd love to see some timings from a C++ compiler or two... Looks like I'll have to revise our standard developer PC configuration.

    "Jarred that would be great to see. The E6300 and X2 3800+ seem close, but the final AMD pricing and the overclocking potential of each could really make either the clear winner for performance per dollar in the midrange segment."

    Yes - this is the test that most people want to see. I';m sure a lot of people are like me, and don't much care about any processors over $200. We want to see that the low end can do!! The AMD X2 3800+ is going to be even lower priced than the E6300, so there may be a good battle at teh low cost end.

    Battle? What battle? The war is over my friend. ;)

    The E6300 wins hands down vs X2 3800+, even more so once both are overclocked:

    Would have been nice to see a Core Duo CPU in there too just for comparison for those of us with laptops who might considering spending $200 on a Merom if it would increase performance 10-20% over a Yonah with the same power consumption. Reply

    Core 2 Duo E6400 2.13GHz is approximately 15% faster than Core Duo T2600 2.13GHz, in addition to the fact that 4MB cache versions are 3% in average faster, it looks estimation of 10-20% faster per clock than Yonah is right, even with the 2MB cache version.
