Professional Application Performance with 3dsmax, Adobe Premier and Photoshop
We start off our page on professional application performance with an updated version of the SPECapc 3dsmax test, updated for version 7 of the application. The scenes being rendered haven't actually changed, but the reference numbers used to compute the composite scores have, so these scores aren't directly comparable to results from earlier SPECapc tests.
Compared to the Athlon 64 X2, the Core Duo comes out on top, but by a very small margin - once again we're faced with a virtual tie.
The breakdown of the rendering composite score can be found below; the scores in the table are render time in seconds, lower numbers are better:
Moving onto Adobe Premier Pro 1.5, this test is actually one that is used by Intel to showcase the performance of the Pentium 4 processor. With the Pentium 4 absent from this comparison, we were curious as to how it compared to the Core Duo and the Pentium M.
As with virtually any media encoding performance, dual-core processors do extremely well, and this case is no different with the Core Duo T2500 seriously outpacing the Pentium M 760.
The Core Duo T2500 is also able to complete the export process in about 97% of the time of the Athlon 64 X2, which once again ends up being borderline negligible for this test, but it is important to note that this advantage comes without the aid of an on-die memory controller.
Our final test is the only other Intel-supplied test in the suite. This one used to showcase the Pentium 4's performance under Adobe Photoshop CS2 by measuring the time that it takes to run a few filters and resize/export images. The script itself is fairly realistic; however, with Photoshop filters, it is easy to favor one architecture over another, so by no means are these numbers intended to be conclusive of Photoshop CS2 performance.

Which should make you think about the supposed "magic" of the on-die memory controller that everyone constantly raves about as being *the* reason why the Athlon64 is as good as it is (hint: there are other reasons, the IMC is just one piece of why).

I don't get it why everyone expects a mobile chip to out-perform a desktop chip.Yonah/Core Duo is specifically a low power optimised dual core processor for laptops. Its fine to use it as an indication of the future conroe/merom, but bear in mind that these will see faster clocks, further optimisations for their specific use (desktop/mobile respectively).
Next month, Intel will have no competition for dual core laptops untill the Turion X2 comes out. Will you think that the mobile version of a desktop processor will be able to perform the same? No, because of optimisations for the all-important mobility factor (battery-life and weight).
If you want an uber-powerful desktop replacement X2 processor-powered laptop, you can do that now. But expect no battery life and an aching back or a soar arm from carrying around a 4kg+ brick. So, Intel is now offering a laptop processor, capable of performing similarly to a desktop processor, but with low power consumption, long battery life and low weight.
What am I trying to say? A Turion X2 may be slower than current Athlon X2s and yes I know 65nm vs 90nm. It probably won't be faster anyway, so Intel have a fast, efficient and cheap processor - hey you expect Turion X2 to be as cheap as the single core version?
Apples to oranges? Get over it! The Core Duo uses DDR2, AMD X2 DDR. Intel FSB, AMD Mem controller. You will never get an apples to apples comparison - its business, competition, differentiated products, call it what you like, you buy AMD, you use different RAM, different Mobos, different drivers to Intel, end of story, so its a comparison of platforms, not CPU.
*end rant*

They don't... and that's the point and why many are impressed with Yonah... that it *does* perform favorably to a desktop platform.

how do you know its going to be cheap? As far as I have seen, there are no prices released for these processors yet. And do you wanna know why we're somewhat dissapointed? Intel (and its fanbois) have been talking about how this new arc. is supposed to be the next big thing. In its current form, its not really.stateofbeasley - Monday, December 19, 2005 - link
http://www.theinquirer.net/?article=26062">http://www.theinquirer.net/?article=26062Price points are the same as the current platform.
Yonah is not NGMA. Yonah is a P6 family processor.
People must read the news before they post!!!!

This isn't really new architecture, the next big thing is supposed to be Intel's NGMA, where alot of changes are going to be made.KayKay - Monday, December 19, 2005 - link
I am an AMD fanboybut the results (power consumption esp.) are very impressive
guess intel wants to keep things competitive
hope amd ups the ante in response

With AMD announcing the use of SiGe in processors coming up very soon, it looks like they could still get a decent drop in power consumption at 90nm. I'd guess that's what they're waiting for to release the Turion x2. I doubt that it will be quite enough to match the power consumption of Yonah, but should mostly suffice until the 65nm shrink. It will also apparently serve to greatly reduce the area required for L2 cache by shrinking the cells. Once that happens I imagine that AMD will hold a small power/performance lead over Merom/Conroe/Woodcrest since adding 64 bit will tend to up their power consumption somewhat. At that point, AMD will be using SOI and SiGe, while Intel will only be using SiGe.As for continuing the ramp of frequencies, I don't think that it's going to play a hugely significant role going forward. That's why everyone is going multi-core these days. It looks like rough performance parity is here to stay between the two. What I think AMD is aiming at is a duopoly in the CPU market. That is the point of the lawsuit, and the greatly expanding capacity that AMD is targeting (Fab36, Chartered, Fab38, etc...). What Intel really needs to worry about is AMD's ability to increase their brand awareness and supply large vendors reliably. Once that happens, Intel will need to compete on price. While AMD is very comfortable living on $100 ASP, that would be catastrophic to Intel's bottom line. I think over the next few years (barring any catastrophic screw-ups by AMD) we are going to see alot of cost-cutting at Intel.
Sorry for the off-topic ramblings, but I tend to look at things from an investors' POV.

So I guess the biggest question for these (at least to me, since I don't have a need for an uber-lappy) is price and a converter for a mobo, and I guess OC-abilty. If they can match clock speeds of the x2s (2.6GHz+) and come out to be cheaper, then I might consider buying one of these, but I don't see AMD's desktop market being threatened, considering Intel's last gasps with netburst (let it die already!).If AMD can milk another 400MHz or so out of its K8 arctechture in its current form, they'll stay competitive with mermom it seems to me. Yonah certainly isn't the AMD killer the intel fanboi's have been heralding it as though.
fitten - Tuesday, December 20, 2005 - link
I've seen a number of "reports" of these Yonahs (Core Duo) hitting 2.5GHz quite easily without even raising the voltage. It's "as if" it were designed to run in the 2.5-2.6GHz range but not released that way... yet.
