AMD's Barcelona to Outpace Intel by 50%
Gr8Apes writes "AMD is upping the performance numbers for Barcelona by stating that "Barcelona will have a 50% advantage over Clovertown in floating point applications and 20% in integer performance 'over the competition's highest-performing quad-core processor at the same frequency'". AMD also claims that the new 3.0 GHz Opterons beat comparable Intel Xeon 5100 series processors in three server-specific benchmarks (SPECint_rate_2006, SPECint_rate2006, SPECompM2001) by up to 24%."
Note that AMD has 3GHz Opterons out now. The frequency advantage at the moment is slim to non-existant in shipped CPUs.
In any case, what matters is what Barcelona will ship at, which has not yet been specified. In any case, if Barcelona lives up to AMD's stated expectations on performance, it will be a killer CPU. Your statement about Intel's potential improvement leaps are spot on, and fall into Inforworld's Tom Yager's statements about Intel which are essentially phrased as "Core 2 is Intel's last hurrah". Why? Because Intel is essentially running on 10 year old technology and is rushing to catch up, despite some of the nifty architectural things they did recently to speed up C2D (integrated L2 cache for example).
I also believe that Intel is now following AMD's lead by leaving extra headroom for those that prefer to OC their CPUs and concentrating more on TDP and stability. I've noticed that Intel's chips since P4 are certainly more stable, while my rather severely OC'd AMD CPU occassionally (twice this year) shuts down, most likely due to heat or a RAM instability (since the shutdowns happen during low usage periods at night, I'll bet the 20% OC'd RAM is probably to blame).
Basically, right now Intel owns the crown, but they own it while comparing to AMD's last gen CPUs which are 3+ years old.
The cesspool just got a check and balance.
