AMD Announces Bulldozer and Bobcat Processor Core Designs – Fusion
By
AMD will reveal new details on its two next-generation x86 processor core implementations, including AMDs unique approach to high-performance, multi-threaded computing, as well as a sub one-watt capable low-power design. The two new designs, codenamed Bulldozer for high-performance PC and server markets, and Bobcat for low-power notebook and small form-factor desktop markets, were designed from the ground-up to address specific customer requirements and compute workloads. The new cores are central to AMDs future roadmap, including the AMD Fusion Accelerated Processing Unit (APU) products and AMDs new high-performance server and client CPUs.
AMD Bulldozer Core Highlights:
- An innovative approach to multithreaded compute performance that balances dedicated and shared compute resources to provide a highly compact, high core count design that is easily replicated on a chip for performance scaling
- New x86 instruction support (SSE4.1, SSE4.2, AVX, and XOP including 4-operand FMAC)
- Advanced power management features
- Manufactured on advanced 32nm process technology
AMD Bobcat Core Highlights:
- Sub-one-watt capable operation
- Out-of-order instruction execution for higher performance
- Estimated 90 percent of todays mainstream PC performance in half the area
- Core power gating and a microarchitecture optimized for low power
- Highly synthesizeable design that moves easily across manufacturing technologies
