Features
The Athlon64 Series offers a few nice features which we are going to discuss now.SSE3
The Streaming SIMD Extensions 3 which AMD got in exchange for AMD64 (Intel: EMT64) from Intel is now used in the AMD CPUs. According to Intel multimedia and multi-threaded applications benefit most from SSE3.NX-Bit - "Enhanced Virus Protection"
AMD introduced the NX-Bit to "improve computer security". This function works only when Windows XP with SP2 is installed and tries to stop execution of malicious code (viruses). Unfortunately this protection "works" only with viruses which use Buffer Overflow techniques.Cool'n'Quiet
The advantage of Cool'n'Quiet is, that the CPU is clocked down (to 5x200 - 1000 Mhz at 1.1V), when no computation power is needed. This reduces heat output and makes it easier to keep the CPU cool, or decrease noise levels and power consumption. Once power is needed, the clock returns back to normal, basically on-demand performance.AMD64
The AMD64 or x86-64 or x64 is a 64-bit processor architecture invented by AMD. It is a superset of the x86 architecture, which it natively supports. The AMD64 Instruction set is currently used in AMD's Athlon 64, Athlon 64 FX, and Opteron processors.AMD64 represents a break with AMD's past behavior of following Intel's standards, but follows Intel's earlier behavior of extending the x86 architecture, from the 16-bit 8086 to the 32-bit 80386 and beyond, without ever removing backwards compatibility. The AMD64 architecture extends the 32-bit x86 architecture (IA-32) by adding 64-bit registers, with full 32-bit and 16-bit compatibility modes for earlier software. Source: Wikipedia
