It's been a long and arduous past few years for AMD’s processor division as they've constantly been one step behind primary competitor Intel. The pain started back in 2006 when Intel launched its Core 2 Duo series, which disposed of the ill equipped Athlon64 X2 range.With no immediate answer, AMD moved the Athlon64 X2 architecture to the 65nm design process, where they ended up with the Athlon 64 X2 6000+ clocked at 3.1GHz. However just as the Athlon64 X2 architecture was meeting the end of the road, AMD unleashed their long-awaited Phenom processors. By that time AMD was doing battle with a hardened Core 2 Quad range. AMD struggled again as the new Phenom X4 processors didn't perform up to expectations. Yet this was the least of AMD’s worries. Their latest creation was plagued by a design flaw that became famously known as the TLB Bug. The quick solution was to disable the CPU's L3 cache, a key feature that when disabled reduced performance further. Around the same time AMD was dealing with the Phenom issues, Intel was ready to show their first Core i7 processors with the arrival of the Core i7-920, 940 and Core i7-965 Extreme Edition.
