► remove from comparison
The Qualcomm Adreno 642L is a smartphone and tablet GPU that is integrated within the Qualcomm Snapdragon 778G SoC. The chip will be available from mid 2021 and will be used mainly in upper mid-range Android devices.
According to Qualcomm, the Adreno 642L GPU offers a 40% improved performance over the Adreno 620 (compared to the specified +50% of the 642 in the SD 780G), its predecessor, which is integrated in the Snapdragon 768G SoC. This is also thanks to the fast LPDDR4X-4200 memory support of the SoC.
The Adreno 642L supports OpenCL 2.0 FP, OpenGL ES 3.2 and Vulkan 1.1.
The Snapdragon 778G and therefore also the 642L is manufactured in the modern 6nm UEV process at TSMC that should provide a good power efficiency.
