AnandTech – Qualcomms New Snapdragon S4: MSM8960 & Krait Architecture Explored

Given Tuesday’s announcement of the first ARM-15 architecture chip from ARM and TMSC, the ball is rolling now. We’re getting closer and closer to desktop capable CPUs in terms of clock, core and now data/instruction bus widths. Once the ARM-15 64bit chip hits the market Qualcomm is going to need to accelerate its development of competing chips. But for now, I think integrating many functions into the same die will have to do. Here now is Qualcomm’s SnapDragon, Read On:

Qualcomm remains the only active player in the smartphone/tablet space that uses its architecture license to put out custom designs. The benefit to a custom design is typically better power and performance characteristics compared to the more easily synthesizable designs you get directly from ARM. The downside is development time and costs go up tremendously.

I’m very curious to see how the different ARM based processors fair against one anther in each successive generation. Especially the move to ARM-15 (x64) none of which will see a quick implementation on a handheld mobile device. ARM-15 is a long ways off yet, but it appears in spite of the next big thing in ARM designed cores, there’s a ton of incremental improvements and evolutionary progress being made on current generation ARM cores. ARM-8 and ARM-9 have a lot of life in them for the foreseeable future including die shrinks that allow either faster clock speeds or constant clock speeds and lower power drain and lower Thermal Design Point (TDP).

Apple’s also going steadily towards the die shrink in order to cement current gains made in it’s A5 chip design too. Taiwan Manfucturing Semi-Conductor (TMSC) is the biggest partner in this direction and is attempting to run the next iteration of Apple mobile processors on its state of the art 22 nanometer design rule process.
