Sweet! 40% performance gain!?!?!? Now that'll help catch up to Core.
AMD just released the roadmap for Desktop processors which tells more about the next-generation K8L architecture based Altair, the first AMDâ€™s Quad Core to be available in 2007 Q3.
Quad-Core Altair will be the AMDâ€™s most powerful desktop processor. With 65nm SOI technology, there are Athlon 64 FX and Athlon 64 X4 versions. The Athlon 64 FX one is designed for performance enthusiast with 4x4 platform supported, while the Athlon 64 X4 one targets for the mainstream segment with SMP (Symmetric Multi-Processor) technology.
According to the industry, Altair would be clocked somewhere between 2.7-2.9GHz, with 512KB L2 Cache for each core such that 2MB L2 Cache in total, and shared 2M L3 Cache. Besides, Altair will get Hyper-Transport 3.0 which doubled its speed from 2GHz in 2.0 to 4GHz. With 65nm SOI technology, its TDP is designed in 125W, still acceptable.
Be noticed that Altair is also compatible for the existing Socket AM2 main board, the only need is BIOS upgrade. Yet Hyper-Transport will get only 2GHz in Socket AM2 main board as ver. 2.0.
Based on K8L architecture, Altair has upgraded Instruction fetch to 32B, enhanced Branch Prediction and Out-of-order load execution, with Double Precision FLOPS/cycle, 128Bit SSE, and Load per Cycle. AMD claim that the new architect would get a great improvement with more than 40%!
Altair is expected to share 10% of the total shipment in 2007 Q3 and reaching 20% in 2007 Q4. Its rival is Intelâ€™s Yorkfield.
