Qualcomm Releases More Details On Snapdragon S4

Qualcomm has finally released more details about its top-end Snapdragon S4 family, which is based on the Krait architecture that we briefly covered back in February this year when it was officially announced at Mobile World Congress.

In a whitepaper (opens in new tab) published a few days ago, Qualcomm sheds more light on the processor, its GPU as well as improvements made compared to the previous generations.

The Krait will deliver improvements of up to 60 per cent compared to the Scorpion family. Clock speeds will vary between 1.5GHz and 25GHz and the number of cores will be either two or four.

As expected new Krait models will come with asynchronous multiprocessing as well as dual-channel memory.

A new GPU will also accompany the new Krait family. The Adreno 225 will add another 50 percent performance to the previous Adreno 220 and will introduce DirectX 9.3 , OpenGL ES 1.1 and 2.0, which will come handy for Windows 8.

One of the first chipsets to launch as a Krait family member will be the MSM8960 which is a true world phone chip supporting EV-DO Rev. B 1x Advanced, EV-DO Rev. B TD-SCDMA, GSM, GPRS, and EDGE plus simultaneous support for GLONASS and GPS, Wi-Fi, Bluetooth, NFC, FM Radio, up to 100Mbps Cat.3 LTE and up to 42Mbps Cat.24 HSPA+. Expect the first devices based on Krait to be released in the second half of 2012.
