Qualcomm Adreno 680 vs Qualcomm Adreno 642 vs Qualcomm Adreno 620

Qualcomm Adreno 680

The Qualcomm Adreno 680 is an integrated graphics card in the Qualcomm Snapdragon 8cx SoC for Windows laptops. According to Qualcomm it is 2x faster than the previous Adreno 630 in the Snapdragon 850 for Windows PCs with a 60% improved efficiency (thanks to the 7nm process). The performance should be similar to a Intel UHD Graphics 620 (e.g. in a 8th gen Core i5) when running native ARM64 compiled Windows apps and games. Running emulated 32 bit games (64 bit games compiled for AMD/Intel are not supported), the performance is notably slower.

Qualcomm Adreno 642

The Qualcomm Adreno 642 is a smartphone and tablet GPU that is integrated within the Qualcomm Snapdragon 780G 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 642 GPU offers a 50% improved performance over the Adreno 620, 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 642 supports OpenCL 2.0 FP, OpenGL ES 3.2 and Vulkan 1.1.

The Snapdragon 780G is manufactured in the modern 5nm LPPE process with EUV at Samsung that should provide a good power efficiency.

Qualcomm Adreno 620

The Qualcomm Adreno 620 is a mobile graphics card for upper mid-range smartphones and tablets (mostly Android based). It is included in the Qualcomm Snapdragon 765G and 765 SoCs and based on the Adreno 600 architecture (like the Adreno 630, which should be fully compatible in software).

According to Qualcomm, the Adreno 620 in the 765G is 10% faster than the one in the 765 and 20% faster than the old Adreno 618. In our benchmarks, the Adreno 620 in the Snapdragon 765G even was 25% faster in selected benchmarks, but the faster CPU will also influence the results.

The GPU supports modern standards like Vulkan 1.0 (according to Wikipedia), OpenGL ES 3.2, OpenCL 2.0 and DirectX 11 (FL 11_1).
