The ARM Mali-G68 MP2 (or G68MC2) is an integrated mid-range graphics card for ARM based SoCs (mostly Android based). The MP2 version uses two of the six possible clusters / cores.
It was introduced mid 2021 in the Samsung Exynos W920 for smartwatches. It is based on the Valhall architecture and is advertised by ARM as a "sub-premium GPU". It offers all features of the Mali-G78 series including improvements for battery runtime and machine learning.
Qualcomm Adreno 640

The Qualcomm Adreno 640 is a smartphone and tablet GPU that is integrated within the Qualcomm Snapdragon 855 SoC. The chip will be available from early 2019 and will be used mainly in high-end Android devices.
According to Qualcomm, the Adreno 640 GPU offers a 20% improved performance over the Adreno 630, its predecessor, which is integrated in the Snapdragon 845 SoC. The enhanced performance is achieved by the Adreno 640 having 50% more FP16 and FP32 compute units (ALUs) than the Adreno 630, while its 7 nm FinFET manufacturing process makes it 20% more efficient too.
The Adreno 640 will also support the Vulkan 1.1 API, something which is possible for other Adreno 600 series GPUs too.
Qualcomm Adreno 685

The Qualcomm Adreno 685 is an integrated graphics card in the Microsoft SQ1 ARM-based SoC. It is similar to the Adreno 680 in the Qualcomm Snapdragon 8cx SoC for Windows laptops but higher clocked and therefore with a higher theoretical performance (2 versus 1.8 TFlops).
