AMD cuts to the core with 'Bulldozer' Opterons

[003]

So core for core Bulldozer is going to be slower than Deneb?? That isn't good at all. Intel isn't making trade-offs like that. If this is true, it seems as though Sandy Bridge will tear Bulldozer apart, never mind Haswell...

here they mention about only a 1.8x increase in performance.....i dont think that is a very big performance leap? or am i understanding this wrong?

It means that two Bulldozer cores will only be 80% faster than a single K10.5 core, not 100% (like a dual core K10.5), or more preferably, over 2.0x as it should be with a new microarchitecture. They are trading off performance in order to add more cores.
