Snapdragon: Krait, Adreno, 4G, future start

This morning, Qualcomm presented in detail the range 2011 with interesting information: the Snapdragon "2" was delivered last week to manufacturers for integration into smartphones late 2011. So back on the chips of the American manufacturer. Snapdragon is the first QSD8250, released in 2009. This smart all-in-One (SoC) integrates a CPU Scorpion - an ARM-compatible core that lies between the Cortex A8 and Cortex A9 in performance - GPU Adreno 200 (from the purchase of the mobile range of ATi ) and - notably - a GPS receiver and a modem.

The chip, still widely used, is the most common. In 2011, Qualcomm still uses the Scorpion core in its products. The first range is the one whose name contains code 8x55: The MSM8255, MSM8655 and the APQ8055. The three different chips on the radio part: in the GSM 8255, CDMA 8655 and nothing in the DPA, for the tablets.

For the rest, there is a Scorpion core (1.4 GHz max), GPU Adreno 205 (twice as fast as 200) and DDR2-333 controller. These are the chips used in most smartphones midrange and high end. With the 8x60 series chips (MSM8660, MSM8260 and APQ8060), double the power but staying on the same architecture.

Still etched in 45 nm chips integrate two cores Scorpio, which operate at speeds asynchronous, and a GPU Adreno 220 which doubles the performance of 205 (and quadruple those of the 200). The frequency of the chip can reach 1.5 GHz. For 2012 (and perhaps 2011), Qualcomm will evolve its chips with a new core, Krait.

The latter should be at the level of future ARM Cortex A15, as expected in 2012. Several chips are expected: the MSM8930, MSM8960 and MSM8270 the APQ8064 and. Not that we know the exact specifications, we know that Qualcomm will offer a wide range of chips, with between one and four cores, and integrate GPU Adreno 220 to two or four cores.

With the high end, one should multiply by sixteen computing power of Adreno 200. Qualcomm should also include some radio LTE (4G) in some variants and obviously reduce consumption by improving the fine print. In terms of frequencies, the company should reach 2.5 GHz with Krait, but the frequency will probably be reserved for certain high-end models and for some uses (such as tablets), as often in the industry.

In fact, Qualcomm is expected to arrive to compete with ARM chips and the GPU of its competitors (NVIDIA, PowerVR, etc..) House with his solution.
