AMD Turion News: Models, Revisions, 100MHz Granularity
In H2 2006 we should expect the following Turion 64 dual-core mobile processors (codenamed Taylor, to be officially released in June 2006):
- TL-60 (2.0GHz/512KBx2)
- TL-56 (1.8GHz/512KBx2)
- TL-52 (1.6GHz/512KBx2)
- TL-50 (2.0GHz/256KBx2)
All of these will be made for Socket S1 using 90nm and will have the revision F. Novelties will support DDR2-667, PowerNow!, AMD-v (virtualization technology). The TDP will be 35W.
The Mobile Sempron series will be represented by Keene-cored models:
- 3500+(1.8GHz/512KB L2)
- 3400+(1.8GHz/256KB L2)
- 3200+(1.6GHz/512KB L2).
Essentially, the only key difference of Keene from Taylor is its single core. Naturally, the TDP is also reduced - to 25W. Besides, it might lack AMD-v support, though it's hard to imagine why an entry-level notebook might need it.
In Q2 2007 we should expect the revision change: Rev.F to Rev.G. This will be related to the transition to 65nm process that will start with Turion X2 64 and then will cover Mobile Sempron. The transition will take some time, so there might be similar models produced at different fabs using different processes.
So what should Tyler and Sherman (the next incarnation of Mobile Sempron) get except for the smaller crystal? The 638-pin Socket S1 will remain the same, though it will hardly become an additional bonus, since we haven't heard about AMD's initiative similar to Intel's Interchangeability Initiative. TDP will remain the same.
But the key innovation will be the 100MHz Granularity, the next generation of PowerNow!. Essentially, it can change CPU clock rate by 100MHz depending on its load. The bottom border of operating clock rate of AMD Turion and Mobile Sempron is still unknown, but we can assume such approach will enable these solutions to successfully compete with Intel Santa Rosa based on Merom. As you remember, for its 2007 year notebooks Intel predicts at least 5 hours of operation.
