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:
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) Intel Pentium Extreme Edition 965 (3.73GHz/2MBx2) Intel Pentium D 960 (3.6GHz/2MBx2) Intel Pentium D 950 (3.4GHz/2MBx2) Intel Pentium D 940 (3.2GHz/2MBx2) Intel Pentium D 930 (3.0GHz/2MBx2) Intel Pentium D 920 (2.8GHz/2MBx2) Intel Pentium D 820 (2.8GHz/1MBx2) Intel Core 2 Extreme X6800 (2.93GHz/4MB) Intel Core 2 Duo E6700 (2.66GHz/4MB) Intel Core 2 Duo E6600 (2.40GHz/4MB) Intel Core 2 Duo E6300 (1.86GHz/2MB) |

Corrected, it was a misprint.Take care,
Anand

Why is the article talking about how Intel is killing AMD on power consumption when AMD is on the top for both idle and load? If you are doing a performance/watt ratio you need to show that on the graph. This page (page 7) just makes the how article look completely baised.Calin - Friday, July 14, 2006 - link
Because the EE SFF processors were hard to obtain by Anandtech even for testing purposes. I'm not sure they are available in retail market any more than Conroe isAnand Lal Shimpi - Friday, July 14, 2006 - link
The Core 2 Extreme X6800 has a performance per watt score of 0.3575 in WME9 compared to 0.2757 for the X2 3800+ EE SFF. I'll put together a performance per watt graph now and see if I can stick it in there.Take care,

I included the performance per watt scores I mentioned above in the review now, hopefully that will make things a little more clear.Take care,
Anand

I don't see the chart, Anand - I hope I didn't accidentally overwrite your change. Sorry!MrKaz - Friday, July 14, 2006 - link
Don't put it because it's a biased chart,Why based on WM9 benchmark? Why not one of the others?
Why put it now, if you never put it when A64 was killing the P4s?

Because AMD didn't real make a big deal about the performance per watt intiative back in the day. They focused on their price/performance instead.MrKaz - Friday, July 14, 2006 - link
So?Just because Intel focuses now on that Anandtech must be obliged to put it?
So for you where was the price/performance (A64 vs P4) charts on Anandtech reviews?
coldpower27 - Friday, July 14, 2006 - link
Yeah, due to their making people aware of it, it has now become a issue.It was only after Prescott, that we became more aware that thermals were starting to get out of control and paid more attention to wattage numbers.
Price/Performance is not as hard to calculate.
