AnandTech has a first look at "Yonah," Intel's successor to the “Dothan” Pentium M and the processor rumored to be Apple’s first choice for next year’s Intel Macs. It seems that the processor is a large improvement over its predecessor in many ways, although it’s still behind AMD’s dual core offerings in terms of power.
From the article:
Although we didn't consider it as such here today, Yonah will be quite impressive on notebooks. The thought of having such a cool running dual core processor in a notebook is honestly amazing, and the performance difference (especially for multitaskers) over what we have today will be significant.
As a desktop contender, Yonah is a bit of a mixed bag. While its performance in content creation applications has definitely improved over the single core Dothan, it still falls behind the Athlon 64 X2 in a handful of areas. Intel still needs to improve their video encoding and gaming performance, but it looks like we may have to wait for Conroe and Merom for that.
This is very interesting news, especially considering yesterday’s rumor about an Intel based Mac PVR. If Yonah truly is slated for that Mac Mini Media Mega Monstrosity (there are so many alliterative options…), will it have enough horsepower for the multimedia aspects of the machine?
It seems clear that Yonah is a perfect fit for the other rumored Intel Macs in January, namely the iBook, Powerbook, iMac, PowerMac… oh, wait, we’ve heard rumors about all of them. If we believe the iBook/Powerbook story, it seems that Yonah will be the kind of low-watt, high-performance processor Steve talked about at WWDC 2005.
It seems that time (well, actually, just a little over a month) will tell.
Just a note that the 945G chipset (and similar variants) seems to be the intro platform, so if you're making a test box now, Dual Core+SSE3+NX+PAE+945(or similar) is your safest best). Also nice that the CPU seems as fast as a dual core 3.0GHz Pentium-D 830 even though it is just 2GHz, and is comparable to Athlon 64 models (most of the time, not in all tests). And, of course, it has the lowest power consumption of the CPUs tested, which makes it look nice for laptops (It IS a mobile CPU after all...)
But I don't know how some of that media performance will impact the "Kaleidoscope" product...perhaps its more than enough for that function, but Merom and Conroe are going to be better for media.
