- Athlon 64 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 Athlon 64 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.

- Athlon 64 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.

- Athlon 64 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.
