Qualcomm's Quad-Core Snapdragon S4 (APQ8064/Adreno 320) Performance Preview

If you've been following our SoC related coverage, you'll probably have come across our coverage of Qualcomm's upcoming SoCs in their Mobile Development Platforms (MDPs). It's an interesting way to get both a feeling for the performance of a given platform before things are final, and to see how much OEMs affect the final performance.

Qualcomm flew us out to San Francisco to take a look at its newest part, APQ8064, which is quad core Krait v2 at up to 1.5 GHz with Qualcomm's new Adreno 320 GPU, and no baseband. This is an SoC destined primarily for tablets, although the combination of APQ8064 and MDM9615 will likely also be a common upcoming platform for the highest end phones.

At present, this is the same Krait CPU as what we've seen in MSM8960 in phones like the USA versions of the Galaxy S 3 and HTC One X. Later on, Krait v3 will emerge with higher IPC and shorter critical paths (and clocks up to 1.7 or 2 GHz) and a resulting 10-15% boost in performance. For now however we're looking at 1.5 GHz APQ8064 with a Krait v2 inside and Qualcomm's newest scalar GPU architecture with Adreno 320. We're going to talk more about Adreno 320 closer to devices shipping, when Qualcomm feels comfortable talking architecture.
