AMD cuts to the core with 'Bulldozer' Opterons

[Sn0wm@n]

How much you wanna bet AMD scales ALOT better with cores than Intel does with hyperthreading.

LOL yeahh they might scale better... but its impossible to have a 100% gain more per core you add... thus my question.....

Of course 100% scaling is impossible, you would need to live in a perfect world where electrons didn't leak out of the system. A 20% hit in multithreaded performance is really good considering each core takes up only 50% of a full core. Even having two full cores would still have a performance hit, smaller than 20%, but nothing scales at 100% efficiency.
