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.

they've got some headroom with clocks to play with, as the recent opterons are showing ;)Beenthere - Monday, December 19, 2005 - link
...and I'm sure some gillible sheep will buy into it.Since the "review" tested apples to oranges AGAIN, it's not of much value for anyone looking to purchase a notebook PC because you used a desktop X2 for comparison to Intel's YAWNER -- a dual core laptop chippie.
To quote this story:
"Intel’s Core Duo launches in January at CES, so if you’ve been thinking about buying a new laptop, we’d suggest waiting at least another month or so. You won’t be disappointed. "
-- Now if that ain't fanboy, what is???
Obviously with Turion stealing a lot of sales from Centrino, it's no surprise Intel is stroking the media to gain as much positive hype on uncompetitive products as it can since it knows it will be at least '07 if not later before it can compete with AMD in any market segment based on performance, value and power consumption. That however won't stop the Intel shilling.

AnandTech is one of the most fair review sites on the net and has been one of the biggest champions of AMD products for years. Your "comments" are little more than pathetic insults against Anand, who is and always will be more credible than you.Furen - Monday, December 19, 2005 - link
I think that he is right to some extent, though. I was hoping for a power consumption comparison between Dothan and Yonah to see which one is better for battery life but it never materialized. I would not say that AMD has a Turion that can compete with Yonah but testing Yonah in a desktop setting and then concluding that it's a heck of a laptop chip without comparing it to other laptop chips leaves a bit to be desired. Also, the tone of this review seemed a quite a bit more Intel-appeasing, if you please, as there was nothing in this review that we didn't see before except for flowery praise about how Yonah does very well without an on-die mem controller.That said I must say that all the asking for a 2GHz 1MB L2/core A64 was pretty retarded. There is no 2GHz 1MB/core SKU so including a fake one just for comparison does not really help since there's no way to get something even similar (the 4400+ is the lowest-clocked 1MB L2 X2). It would have been nice to see an X2 4600+ (the second-best A64 SKU) compared to this Yonah (the second-best one) but I guess the 4200+ is more inline with its price.

An overclocked Opteron 165 or underclocked Opteron 175 might have been an idea? forget about prices.
I think AMD still has some tricks up there sleeves regardless of what there roadmaps might say.

Eliminating clockspeed and using the best cache available sets the baseline for comparison, by keeping as few items of difference between the chips as possible. I fully agree with the choice, and, moreover, am quite positive there will be something out in the Turion line that will be quite similar to the 2ghz, dual channel, 1m/core cache that was used for testing.I think it's kind of funny to see us finally returning to tests where comparing close to exactly the same clockspeed produces even mildly comparable results. I say that because years ago that's what we used to do all the time, and finally things have come nearly full circle.

Ah, but we still don't know how DDR2 will affect K8 (or K9, as AMD likes to call the dual-cores) performance. Maybe AMD will increase the L2 cache data width from 128bits to 256bits (the Pentium M has a 256bit interface) to make up for the additional latency, though I doubt it.vijay333 - Monday, December 19, 2005 - link
"Now if that ain't fanboy, what is???"It's called giving good advice. Not an Intel owner myself, but even I would appreciate this info as AT obviously has more info on this. Would you rather buy a laptop now and then regret the purchase when something much better comes along in just a month from now? AT is not telling you to buy an Intel based machine, just to wait a month to get a better idea of what your options are. If you have read AT for a while, you should know that they are definitely not biased towards Intel...

Something new and better will always be out "a month from now". Get use to it.bob661 - Monday, December 19, 2005 - link
Looks like just a P-M with two cores to me. Whoop-de-doo.
