Bulldozer Opterons totally frags Intel Xeon in SPEC benchmark
Some readers complain that I was quoting AMD's press release on Bulldozer Opteron's towering performance numbers. Now, the numbers have been validated and published on Spec.org. Let's have a look at the highest scores for the Bulldozer.
In SpecFp2006_rate, a 2P Bulldozer Opteron server achieves a score of 403. Simply put, there is no 2P Xeon can match this score.
In SpecInt2006_rate, a 2P Bulldozer gets a score of 543. This is almost 30% higher than a 2P Xeon X5690.
Some readers say it's not fair to compare the 16-core Opteron to the 6-core/12 thread Xeon. They missed the whole point of measuring performance per watt. The 6-core Xeon consumes 130watts. The 16-core Opteron consumes the same amount of power. With more cores, the Opteron can simply do more within the same thermal footprint.
How will Intelers argue against these hard numbers?
They resort to the usual low IQ, low education ad hominem attacks. Just read their comments on my blog, and see how low they are.
