2.5GHz quad-core Qualcomm Snapdragon with Adreno 420 GPU nearing release
Earlier this year Qualcomm’s purported processor road map was leaked onto the Internet. Among the various processor models listed was the APQ8084, a Snapdragon 800 variant with a new GPU – the Adreno 420.
It looks like Qualcomm is sticking to its roadmap as a recently spotted benchmark from AnTuTu, shows the APQ8084 running at 2.5GHz. The quad-core test device was running Android 4.3 and sported the new Adreno 420 GPU.
Current thoughts are that the new Adreno 400 series will support DirectX11 and WebGL2.0. In terms of performance it should have a 10% greater pixel fill rate than the Adreno 330. The Ardeno 420 also has a higher clock speed at 500MHz. The combined APQ8084 SoC package will feature hardware decoding for the new H.265 standard plus it can handle 4K video playback. It also supports 802.11ac Wi-Fi and Bluetooth 4.0.
The new SoC can also handle 64-bit DDR3 memory. This isn’t to be confused with 64-bit processing in the CPU, but rather when data is fetched from the memory the data path is 8 bytes wide. However the CPU will only be able to receive the data 4 bytes at a time.
The APQ8084 isn’t expected to be available until 2014 so any initial devices using the chip will likely be announced at next year’s CES.
