Intel’s 7400-series Xeons: Up to six 45nm cores + up to 16MB of Level 3 cache!

Intel has at last launched its six-core range of Dunnington CPUs amidst leaked rumours that have been rife since earlier in the year. An added extra for server technology is that a server motherboard can combine up to 16 of these chips in a single machine; giving a total of 96 cores in one box!

On the lower end of the range is the Xeon L7455 with 6 cores clocked at 2.13GHz and 12MB of Level 3 cache. Each of the 45nm cores amazingly only uses around 11 watts of power; a fact that is sure to please environmentalists.

Top of the pile is the Xeon X7460 with 6 cores clocked at a nippy 2.66GHz each. It also has 16MB of Level 3 cache, and a TDP of 130W -  As a result it can get rather warm; but is nevertheless relatively efficient. Five other 7400-series Xeons have also been released; bringing the total to date to 7. These are listed below:-

CPU           TDP           Cores           Speed           L3 cache

X7460             130W                  6                  2.66GHz                16MB

E7450              90W                   6                  2.4GHz                  12MB

E7440              90W                   4                  2.4GHz                  16MB

E7430              90W                   4                  2.13GHz                12MB

E7420              90W                   4                  2.13GHz                  8MB

L7455              65W                   6                 2.13GHz                 12MB

L7445              50W                   4                 2.13GHz                 12MB

Overall this entire range of chips demonstrate excellent increased power efficiency; which, combined with their relatively standard clock-speeds should give good overall performance.
