many Android phones over the past year and a half, not to mention the only SoC available in Windows Phone 7 devices.
In the coming months we’ll see the first dual-core Cortex A9 based NVIDIA Tegra 2 SoCs ship in devices. Sometime next year we’ll see A9 based OMAP4 SoCs in smartphones as well. So what does Qualcomm have in store for us over the next few years?
First we have the MSM8260 and 8660 SoCs. These are based on Qualcomm’s current generation technologies: integrating two Scorpion cores and an Adreno 205 GPU on a single 45nm die. The 8260 features HSPA+ support, while the 8660 supports HSPA+, CDMA2000 and 1xEV-DO Rev. B. These two dual-core SoCs will run at 1.2GHz. We should see a GPU upgrade here as well.
The 8x60 SoCs started sampling over the summer and we should expect to see them in high end smartphones sometime in 2011 at the earliest.
Inside the MSM8960 are two next-generation processor cores, presumably out-of-order as Qualcomm is promising 5x the performance of the original Snapdragon chip (2x for the move to dual cores and the rest due to OoO, larger caches and other architectural tweaks perhaps?). Qualcomm isn’t disclosing clock speed at this time.
Power consumption is said to be 75% lower, however that seems very aggressive compared to what we have today. It’s unclear if Qualcomm is talking about active or idle power, or what version of Snapdragon it is comparing to (65nm or 45nm).
separately announced that the Adreno 3xx GPU would be used in SoCs from 2011 - 2013 on a 28nm process. This appears to be the GPU family used in the next-generation Snapdragon. Even more interesting is Qualcomm stating that Adreno 3xx will have performance similar to the Xbox 360/PS3.
If that’s indeed the level of graphics performance we’ll see in the next 3 years, being able to play Xbox 360 titles on Windows Phone 8 may not be too far fetched.
