Overall System Performance with Winstone 2004
Business Winstone 2004
Business Winstone 2004 tests the following applications in various usage scenarios:
The FP/SSE enhancements to Core Duo have no chance to shine in your everyday run-of-the-mill business applications like Word and Outlook, not to mention that the workload is not heavily multithreaded, so there's no benefit from a dual core processor. So from a performance standpoint, all we see from the Core Duo is a similarly clocked processor to the Pentium M 760, but with a higher latency L2 cache, which explains the performance deficit.
The Athlon 64 X2 running at 2.0GHz with a 1MB L2 per core manages to slightly outperform the Core duo T2500, however the performance margin is negligible.
Multimedia Content Creation Winstone 2004
Multimedia Content Creation Winstone 2004 tests the following applications in various usage scenarios:
Not all of the Core Duo's advantage over the Pentium M is due to its dual core nature, but it does account for some of it.
But as we saw in our original article, at 2.0GHz, the Core Duo T2500 just isn't able to offer performance comparable to the Athlon 64 X2 at the same speed. It is worth noting that L2 cache size doesn't really make a difference here to the X2 at all, just clock speed. Thanks to the Athlon 64's on-die memory controller, the architecture is inherently less sensitive to cache size than more conventional designs that rely on an external memory controller.

I doubt a a laptop uses 108W and got a x800XT. That powerchart is close to useless.A Core Duo laptop is 31 peak for CPU and 2.5 for the 945GM. A single core tution is 35W. unless you want 25W part, but then we gotta use the lower intel part aswell.
Dualcore Turion wont even stand a chance until it get 65nm.
Furen - Tuesday, December 20, 2005 - link
The 25W Turion parts are $5 more expensive than the 35W parts, hardly comparable with the price difference between regular and LV Intel CPUs. I agree with you in that I dont expect 90nm Turions to match Yonah's power consumption but I must say that what I've heard about the Yamato platform (which, to tell the truth, is almost nothing) makes me think that it'll be a closer match than we think.Missing Ghost - Monday, December 19, 2005 - link
What, no 64 bit?I won't buy this.
fitten - Tuesday, December 20, 2005 - link
Do you actually use 64-bit or is it just a feature checkbox? I bought some Athlon64s because they were 64-bit and allowed me to test the software I write on a 64-bit platform, for example... not that the codes I actually write require many of the features of 64-bit, though. In the past, I have written and worked on a number of projects that actually need 64-bit (typically just very large datasets which can just be used flat in 64-bit as opposed to all sorts of tiling and paging on a 32-bit machine).Chickan - Monday, December 19, 2005 - link
Did anyone else notice that the numbers in the graph for Black and White did not match up with the spreadsheet below it? According to the graph, the Core Duo hit 44.5 FPS, the same as the X2 2ghz w/ 1mbx2, but in the sheet below, it is reported to only do 40.1 FPS, lower than even the Pentium M. In fact, it performs the worst out of all the CPU's there, at every resolution, even though this is not reported, nor mentioned.I also find it interesting that Intel's new line is only able to match X2's, not beat them. Either way, lets see some new stuff from AMD!
KazenoKoe - Monday, December 19, 2005 - link
Odd, the article clearly has it at 42.3fps on both the graph and the table. The Pentium M got 40.1 and the X2 2GHz/1MB got 44.5.WitchKing - Monday, December 19, 2005 - link
I enjoyed reading this 2nd article on the next Intel platform.Although I am basically in favor of AMD since Athlon platform, I am quite glad that Intel is closing the performance gap. It will make AMD move further ;-)
Anyway, it should be quite interesting to see how these 2 platforms compare in 64-bits tasks (Windows XP-64, Vista (is a 64-bits version available yet?) and linux based).
A 3rd opus of this article maybe? ;-)

Yonah does not support x86-64, so doing 64 bit testing is not possible.phaxmohdem - Monday, December 19, 2005 - link
I thought this review was much better than the first. Thanks guys. It pretty much illustrates the same thing, but it is interesting to read about new CPU's none the less.I don't mind the name personally, I think that we uber-nerds don't like it because we actually know what a core is in regards to a CPU. Your typical idiot customer doesn't know what a Core, or Processor die is, and Core is just another brand name like Pentium.
While these chips look freaking awesome for laptop use, I must admit I will ver very dissapointed it Conroe launches, and only brings Intel back to equality with AMD. When a new generation of CPU launches, I generally like to think that they are releaseing something to regain their status as performance leader, not just level the playing field. (Though I guess PII/PIII/P4 al launched with worse performance than the high end of their predecessors)
tfranzese - Monday, December 19, 2005 - link
If memory serves, the only one to launch with a loss in performance was the Pentium 4. The Pentium II was a great advancement over the Pentium it replaced (not the Pro) and the Pentium III performed equally, though was available at higher clock speeds. That said, I don't know where you got to grouping the PII and PIII in with the P4's poor launch status. Willamette was a joke.
