14 DAY TRIAL // AMD has finally unveiled its awaited 65nm roadmap. As the entire CPU line from AMD will switch to 65nm process, there will be changes, most of them related to the TDP and the correspondence between the rating and the actual frequency.
First comers are dual core Brisbanes which will be using no less than 6 different clock speeds, 5 of them being manufactured on the 65W TDP. The fastest CPU is rated at 5400+ and works at 2.8GHz with a higher TDP of 76W. The other five brothers? parameters are the following: 5200+ @ 2.7 GHz; 5000+ @ 2.6 GHz; 4800+ @ 2.5 GHz; 4400+ @ 2.3 GHz and 4000+ @ 2.1 GHz. All CPUs incorporate 2x512KB level 2 cache. Note that both speed and in some cases, the quantity of cache differs from Brisbane to Windsor counterparts.
Energy Efficient Brisbane with a TDP of 35W will arrive in the second quarter of 2007 and will be using the following ratings: 4400+ @ 2.3GHz; 4200+ @ 2.2GHz; 4000+ @ 2.1GHz and 3800+ @ 2GHz.
As for single core parts, they will also use 65nm and two lines of CPUs will result, one using 512KB of level 2 cache (Lima) and another with less cache, meant to keep the old Sempron line alive (Sparta). As for the actual working speeds, Lima cores will have 3 CPUs with the following specifications: 4000+ @ 2.6 GHz; 3800+ @ 2.4 GHz and 3500+ @ 2.2GHz. Sparta line will feature 4 CPUs, the first two using 256KB of level 2 cache while the other two will only incorporate 128KB: 3800+ @ 2.2GHz; 3600+ @ 2GHz; 3500+ @ 2GHz and 3400+ @ 1.8 GHz.
Some of them may turn out to be quite good overclockers so if you have the patience to wait until spring when the first single core parts come out, you will be pleased. All things considered, AMD won?t catch INTEL with this move on the performance side but at least, it will equal the power consumption of Core 2 products. And maybe the overclockability.
