No. The AMD64 architecture was designed from the beginning for multiple cores on a single piece of silicon. For AMD desktop quad-core processors, we have added the additional two cores and L3 cache – other resources like the integrated memory controller and HyperTransport™ technology links remain on the die. This allows quad-core AMD processors to share a single package and offers an easy upgrade path. AMD Phenom™ processors are designed as true triple- and quad-core products based on award-winning AMD64 technology, as well as:
- Improved overall performance
- With a true quad-core design, cores communicate on the same piece of silicon, with Direct Connect Architecture and cache and core performance enhancements
- Infrastructure Compatibility
- AM2 and AM2+ package and socket compatibility
- Unique Shared L3 Cache
- Fast access to more of the most accessed data
- 128-bit Floating Point Unit
- Larger data paths can mean improved speed in floating point calculations
- Integrated DDR2 Memory Controller
- Support for DD2-800 and planned support for DDR2-1066 pending JEDEC specification approval and release
- Enhanced Efficiency with AMD PowerNow!™ Technology (Cool’n’Quiet™ Technology)
- New features enable better and more dynamic performance with increased efficiency
