Leaked Qualcomm document reveals Krait specs

Leaked documents purporting to reveal the as-yet undisclosed specifications of Qualcomm's upcoming ARM-based Krait processor, the next generation of the Snapdragon architecture, have appeared online.

A leaked PDF file, which bears the hallmarks of being a legitimate internal briefing document, has been spotted by the guys over at MobileTechWorld and promises to shed some light on the chip that Qualcomm hopes will be taking Intel on in the laptop world.

The document, which has been removed from the file-sharing site on which it first appeared from a source unknown, details the Snapdragon MSM8960 Krait processor, which Qualcomm has already confirmed to thinq_ will form the basis of the company's assault on the laptop market.

The first system-on-chip design from Qualcomm to receive Windows 8 certification, the MSM8960 will allegedly launch as a dual-core chip running at between 1.5GHz and 1.7GHz with 1MB of L2 cache memory. The document claims that a dual-channel 500MHz LPDDR2 memory controller is included, along with LTE or 3G data connectivity depending on client requirement and the model chosen.

The chip is allegedly capable of capture and playback of 1080p HD video at 30 frames per second, and can capture 3D images at resolutions of up to 20 megapixels from an optional camera unit. The graphics processing portion of the design is, the document claims, based on the Adreno 225 accelerator design, offering 125M triangles-per-second fill rate and including DirectX 9 Shader Model 3 support.

The document also details a lower-end part, the MSM8930. Featuring a single-channel 533MHz LPDDR2 controller, the dual-core part will apparently ship after its flagship brother at clock speeds of 1.0GHz to 1.2GHz and packing the Adreno 305 3D accelerator.

Finally, the document reveals the promised quad-core design, the MSM8974. Featuring four processing cores running at 2GHz to 2.5GHz and 2MB of L2 cache, it's a beast of a chip even before the powerful Adreno 320 3D accelerator is taken into consideration. It's a revised design on the APQ8064 unveiled at MWC earlier this year, but there's a catch: the document claims that the chip won't be launching until Q1 2013, giving rival Nvidia's Tegra 3 quad-core chip a full year head start on the market.

We contacted Qualcomm to discuss the accuracy of the leaked document's claims, but didn't get far. "We aren't able to comment on this issue at the moment," a spokesperson explained. While that's not a confirmation it's also far from a denial, suggesting that the document is indeed accurate.
