Intel Core Duo (Yonah) Performance Preview - Part II
At the end of November we finally did what we had been waiting to do for so long - provide the first performance benchmarks of Intel’s Yonah processor, the dual core successor to the highly acclaimed Pentium M. However, our initial performance investigation was not without its flaws. Given the short amount of time we had for benchmarking we were forced to compare to older numbers from previous reviews, which unfortunately lacked updated gaming, encoding and 3D rendering tests.

Despite the shortcomings of the initial article, we did manage to get a good look at the performance we could expect from Yonah. Mainly, that it was a fairly strong successor to the single core Pentium M and even more impressive was that it offered performance equal to that of AMD’s Athlon 64 X2 without an on-die memory controller. Many AnandTech readers kept our methods in check however by quickly pointing out that the Yonah vs. Athlon 64 X2 comparison wasn’t exactly fair, as Yonah is equipped with a full 2MB of L2 cache, whereas the Athlon 64 X2 3800+ we were comparing it against only had 512KB per processor, possibly painting Yonah in a better light.

So for this follow-up we’ve done two important things; for starters, we’ve updated the benchmark suite considerably, including modern day games and a few professional-level applications to hopefully get a better perspective on Yonah’s performance. We’ve also included an Athlon 64 X2 running at 2.0GHz, but with each core having a full 1MB L2 cache, making the Yonah vs. X2 comparison as close to even as possible (not mentioning the fact that AMD has twice the advantage in this round, with both a larger L1 cache and an on-die memory controller, but it should make things interesting).

We won’t be revisiting the issue of power consumption, as we already did that at the end of our last article but needless to say, Yonah is the most efficient dual core processor we’ve tested to date. Granted that it does have the advantage of being on Intel’s 65nm process whereas the Athlon 64 X2 is still based on AMD’s 90nm process, but given that AMD is around a year away from transitioning to 65nm it is an advantage that Intel has the right to enjoy.

Price will determine the victor I assume.

well, I can buy an Desktop x2 right now and get a motherboard easily (infact, I just did)

Can I do the same for a Yonah? Not really it's a pain in the *** finding a motherboard and it isn't cheap either.
