It seems like Qualcomm is sticking to its earlier-this-year leaked processor roadmap, as a recently spotted AnTuTu’s benchmark shows the new model APQ8084 speeding up to 2.5GHz. The test device with the new Snapdragon 800 quad-core variant and the new Adreno 420 GPU was running Android 4.3.
Adreno 400 series with DirectX11 and WebGL2.0 support will in terms of performance give a 10% greater pixel fill rate than the Adreno 330. The Ardeno 420 also has a higher clock speed at 500MHz, while the combined APQ8084 SoC with H.265 standard hardware decoding will handle 4K video playback. There is also support for 802.11ac Wi-Fi and Bluetooth 4.0.
Handling 64-bit DDR3 memory isn’t a problem for the new SoC, where data is fetched from the memory in 8 bytes wide data path. However, this should not be confused with 64-bit CPU processing, where received data can only be 4 bytes at a time.
We can estimate that APQ8084 will not be available until 2014, making initial devices with the chip to be announced at next year’s CES.
