Qualcomm Adreno 643 vs Apple A12 Bionic GPU vs Qualcomm Adreno 644

Qualcomm Adreno 643

The Qualcomm Adreno 643 is an integrated graphics unit (iGPU) that is used in the Qualcomm QCM6490 and QCS6490. The SoC is not only intended for use in Android-based smartphones and tablets, but also for IoT products with Linux, Ubuntu or Windows 11 IoT Enterprise. In the QCM6490 and QCS6490 the 643 clocks at 812 MHz.

Apple A12 Bionic GPU

The Apple A12 Bionic graphics card is the second generation of integrated GPUs that was designed by Apple and not licensed by PowerVR. It can be found in the Apple iPhone Xs (Max) and Xr includes 4 cores and supports Metal 2. According to Apple, the 7nm manufactured GPU offers 50% increased performance compared to the A11 Bionic. Therefore, it should be one of the fastest graphics cards for smartphones (like the Adreno 630).

The architecture should be similar to the older PowerVR graphics cards like the A10 GPU, but currently Apple is not disclosing any information about the architecture.

Qualcomm Adreno 644

The Qualcomm Adreno 644 is a smartphone and tablet GPU that is integrated within the Qualcomm Snapdragon 7 Gen 1 SoC. The chip was announced mid 2022 and was available in early 2023 in upper mid-range Android smartphones.

According to Qualcomm, the Adreno 644 GPU offers a 20% improved performance over the Adreno 642, its predecessor, which is integrated in the Snapdragon 780G SoC. This is also thanks to the fast LPDDR5 with 3200 MHz. In our benchmarks with the Mi 13 Lite however, the performance was only on par with the old Adreno 642.

The Adreno 644 supports OpenCL 2.0 FP, OpenGL ES 3.2 and Vulkan 1.1.

The Snapdragon 7 Gen 1 is manufactured in the modern 4nm process with EUV at Samsung that should provide a good power efficiency.
