I heard people say that how Yonah sucks compared to X2 which is a previous gen processor, and how dual 2GHz Sossaman manages to barely beat single X2, even though the scales are linearly scaled according to clock speed. I have something to say about that.
First of all, Cinebench scales NEARLY LINEARLY according to clock speed. Take a look at X2 score.
4800+=638
3800+=536
638/536=19%, which is very close to 2.4GHz/2.0GHz of the processors. It has 95% scaling, which is NEARLY LINEAR.
Second, is that even though they say 2.0GHz Yonah score is scaled linearly, it is not if you calculate.
2.0GHz Yonah=521
1.5GHz Yonah=383
521/383=36%, but 2.0GHz/1.5GHz=33%
1.33x383=509, that's the actual linear score
It seems that 2.0GHz score that THE SITE SAID ITS LINEAR, is actually SUPER-LINEAR!!!
Yonah vs. Dothan advantage per clock.
1.5GHz Yonah=206
1.73GHz Dothan=228
228/206=10.7%
1.73GHz/1.5GHz=15.3%, on 95% scaling, performance advantage by higher clock is=14.6%
However, 1.73GHz Dothan is only 10.7% faster than 1.5GHz Yonah, not 14.6% faster. Per clock Yonah has---1.146/1.107=3.5% advantage per clock over Dothan
Going to dual core for ALL processors give approximately 85% advantage over single core at same clock speed. Cinebench isn't affected at ALL by memory bandwidth: http://www.pcper.com/article.php?aid=133&type=expert&pid=13
What makes Yonah faster per clock over Dothan?? I am not sure. Enhanced IDIV performance?? Better floating point?? Better cache architecture??(probably not as Cinebench is not affected by memory bandwidth) Better prefetch??
Whatever, I think this one particular benchmark doesn't show anything about Yonah's performance. They could have tested a benchmark that has Yonah own everything then people would be saying the site is Intel-biased, its cheating benchmark for Intel CPUs. If they show a benchmark that shows contrary, people would be saying, Yonah is dead, Intel is dead or whatever.
Yonah is January 6th. Looking at how long Dothan review from Anandtech took to surface, plus Sonoma benchmark never showed, I bet I won't be looking for Anandtech benchmarks, unfortunately.
