AMD Barcelona beats Xeon in SPECcpu2006, FP 50% , Integer 20%
AMD Barcelona beats Xeon in SPECcpu2006, FP up to 50% , Integer up to 20%. Thanks God. :)
However, please note at the same frequency remark. If correct, that means Intel is still better, right? Why is better? Because it is in 65nm and new architecture. Well, new K10 core Barcelona is too made in 65nm. Beside, AMD's advanced strained SSOI manufacturing process is better than 30 years old Intel's bulk silicon. Until 45nm ramp arrive in 1Q2008, or even than. And for the first time ever, AMD's weakest point second source fab, is luckily solved by the Barcelona launch time. :)
If even at this moment Opteron is better than Xeon in SPEC tests, let estimate Barcelona's performance improvements. Approximatively 50% -15% equals 35% max in FP.In SPEC integer 20% -2,5% peaks 17,5% . Quite decent K10's purely architectural improvements, IMHO.
Thus, Barcelona could lower its clock at 2,5 Ghz and still beat Intel's 3Ghz top Xeon. In all aspects: performance, reliability, power consumption, prices.
However, AMD fans think (not without substantiated benchies) that Intel should run much higher than 3 GHZ to match the 2.5 GHz K10 part. OMG
So, that is the real reason why Intel so much talks about Penryn. Much more than AMD on Barcelona, just around the corner. Because Intel has nothing else ready for market at this moment.
Yeah, What if the AMD Opteron™ processor never existed?
May is the month when the first Barcelona benchmarks should be released. In wild, of course. :)
Intel's response is given here. And here. Even now.Congrats.
