De AMD K8 ofwel Hammer is de achtste-generatie processor van AMD. Wat deze processor vooral bijzonder maakt is een 64-bits uitbreiding van de IA-32 instructieset. Met deze x86-64 instructieset is de Hammer in staat om te profiteren van alle mogelijkheden van een 64-bit brede processor, terwijl backwards compatibiliteit met bestaande IA-32 software wordt behouden. De implementatie van de Hammer processor is daardoor veel minder ingrijpend dan van de 64-bit Intel Itanium, die nieuwe IA-64 software vereist om optimaal te presteren.
quote:
• K8 features better branch prediction algorithms and bigger TLB, which will make Athlon 64 run faster than Athlon XP working at the same clock frequency.
• Integer pipeline of K8 is a little longer, which allows reaching higher clock frequencies. The integer pipeline of this processor has 12 stages altogether, while the FPU – 17 stages, against 10 and 17 stages respectively by Athlon XP.
• K8 supports SSE2 instructions. This way this processor will support all existing extensions of x86 instructions set, which will allow it to work faster with applications optimized for Intel Pentium 4 processors.
• K8 feature a built-in DDR SDRAM controller, so that it can communicate with the memory directly thus reducing the latencies on data requests.
• The CPU and the South Bridge will be connected with the HyperTransport bus with up to 3.2GB/sec bandwidth in each direction.
• K8 processor supports x86-64 technology, which allows it to work in special 64bit applications.
