Multitasking Content Creation
MCC Winstone 2004
Multimedia Content Creation Winstone 2004 tests the following applications in various usage scenarios:
. Adobe® Photoshop® 7.0.1
. Adobe® Premiere® 6.50
. Macromedia® Director MX 9.0
. Macromedia® Dreamweaver MX 6.1
. Microsoft® Windows MediaTM Encoder 9 Version 9.00.00.2980
. NewTek's LightWave® 3D 7.5b
. SteinbergTM WaveLabTM 4.0f
All chips were tested with Lightwave set to spawn 4 threads.
While the 2.0GHz Yonah processor is faster than the Pentium D, the X2 3800+ manages to hold a marginal 6% lead over Intel's newcomer. This is somewhat of a disappointment, given the enhancements Yonah has that are specifically designed to improve performance in situations like this. While Yonah is doing better than Dothan here, it's not good enough to beat AMD.
ICC SYSMark 2004
The first category that we will deal with is 3D Content Creation. The tests that make up this benchmark are described below:
"The user renders a 3D model to a bitmap using 3ds max 5.1, while preparing web pages in Dreamweaver MX. Then the user renders a 3D animation in a vector graphics format."
The situation changes dramatically when we look at SYSMark's ICC performance, here the 2.0GHz Yonah is right on the heels of AMD's Athlon 64 X2 4200+, maintaining just under a 7% lead over the identically clocked X2 3800+.
Next, we have 2D Content Creation performance:
"The user uses Premiere 6.5 to create a movie from several raw input movie cuts and sound cuts and starts exporting it. While waiting on this operation, the user imports the rendered image into Photoshop 7.01, modifies it and saves the results. Once the movie is assembled, the user edits it and creates special effects using After Effects 5.5."
Yonah continues to fall in between the X2 3800+ and the 4200+, this time being much closer to the former.
The Internet Content Creation suite is rounded up with a Web Publishing performance test:
"The user extracts content from an archive using WinZip 8.1. Meanwhile, he uses Flash MX to open the exported 3D vector graphics file. He modifies it by including other pictures and optimizes it for faster animation. The final movie with the special effects is then compressed using Windows Media Encoder 9 series in a format that can be broadcast over broadband Internet. The web site is given the final touches in Dreamweaver MX and the system is scanned by VirusScan 7.0."
Once more we see that Yonah isn't perfect, being outpaced by the X2 3800+ by around 8%. Of course power consumption matters, but we'll save that comparison for the end of this article :)

Also, isn't there a way to disable the second core in BIOS?I think it's definitely possible to make your dual-core chip into a single-core for testing.

No, since it is a CPU with double execution units, rather than 2 CPUs linked together.fitten - Wednesday, November 30, 2005 - link
I've not seen that stated anywhere. What I've seen is that there are two cores, two independent L1 caches, and a shared L2 cache.Anemone - Wednesday, November 30, 2005 - link
The reason it was compared against the X2 is simply because that is where the next gen Turion "may" land in performance. Power consumption in this test is nice, but not really relevant to the new Turion, nor is it relevant to the mobile arena where AMD with integrated controller does well against P-M plus external controller consumption (well though Intel is better so far).I had a feeling things were going to turn out this way. That cache on the P-M is really what makes it such a nicely performing chip. Weakening that was really the telling test in all this. It's nice that you put that test first. The dual core Turion is going to be very close in release timing to Yonah, and quite a few samples of the chip are already out there, but I'd bet AMD is keeping its cards close, as it has less of a need to prove a point.
However, from a mobile perspective AMD's use of Via and ATI chipsets really will be the telling factor, and will impact the "you get it all" bundle of a notebook. Where, after over a year, is Nvidia and a pci-e mobile chipset for AMD? Turion is almost out the door and they haven't even spoken up yet. That's probably because they won't be there when Turion releases. If Nvidia had no chipset on the desktop, the competition would be starkly different right now, and a good many folks know this to be true. So I'm expecting the dual core Turion to do incredibly well. 64 bit isn't an end all be all, but it will be a wonderful perk when Vista comes, and Vista will be here sooner than previously expected. Power consumption "may" favor Yonah, however Intel is doing what they always do, when a chip performs so-so, they push up the clockspeed. When they find out what Turion has on the table, they'll put out the EE version of Yonah to try to match it. THAT I bet, won't be so power friendly.
Intel is improving on Yonah with Conroe. But remember that the low latency L2 is what gave the Dothan its ability to stand in the A64 arena. That got lowered and we see the results. Now imagine what will happen when they "gently" increase the pipeline of Conroe vs P-M/Yonah. It'll drop a bit again. Against that you'll have architecture improvements and higher clockspeed (Conroe is expected to clock higher). That might end up making Conroe only "slightly" better than Yonah. That is why the marketing of th two can overlap, probably.
So IF (and it's not promising) Nvidia gets the NF4 into a mobile format and gets builders to use it on the new Turion dual cores, we might see some interesting things from the AMD side. If not, they stay as now, a niche market only. ATI chipsets aren't going to change that, much as they have not done much to the desktop side of things.
IF Yonah clocks at 2.6ghz you may see some competitive desktop systems to A64 X2's. It will rule the mobile roost unless the above happens for AMD. Conroe had better make some dramatic improvements to even Yonah's ability, though I'm doubtful, or putting both Yonah and Conroe on the desktop will simply hand even more of the market to AMD. On the mobile front, again unless the above happens for AMD/Nvidia on a mobile chipset, you will watch Yonah/Conroe rule the mobile roost.

Intel just now managed to close the gap between them and AMD as far as dual core is concerned. I dont care if one is a mobile part and the other is not, mobile computing is of no interest to me and even less dual core mobiles. But it gives a good idea of what to expect.The numbers are there. Yonah isnt groundbreaking besides the fact that it is a dual core - and the desktop versions probably wont be either. Wow, thats late...

TG Daily: What is your reason for not including support for 64-bit technology in Yonah? Why is it going to be supported only in Meron?Perlmutter: Like everything in technology or life, it is all a matter of timing. Integrating unneeded features into a processor means a waste of power consumption. Our assumption was, and still is, that 64-bit extensions are not the most important thing required from a processor, not even in the beginning of 2006. We believe this will change with Windows Vista, when applications start migrating to 64-bit, and we want to be ready then, and not a minute earlier.

64-bit extensions = more transistors, which means higher power consumption.Donegrim - Wednesday, November 30, 2005 - link
If this is cheaper than the X2 3800, and overclocks really well on the desktop (say, 2.7-3ghz or so), then I could see myself being tempted by it. As long as the 'secret' motherboard isn't as ridiculously overpriced as current dothan desktops.Griswold - Wednesday, November 30, 2005 - link
WHat makes you think that thing will go to 2.7-3ghz? *laff*Donegrim - Wednesday, November 30, 2005 - link
Well the x2 3800 that consumes much more power (therefore is hotter) consistently goes to at least 2.5ghz, so I don't think it's unrealistic for a lower power chip to go further. Plus the FSB is nice and low, which makes for a good start with the overclocking.
