We’ve heard about AMD and Samsung’s joint efforts to develop a mobile GPU for the better part of the past year. Initial benchmarks showed that it handily outperformed Apple’s A14 Bionic across the board. Now, a new set of benchmark results have emerged online, and they pretty much sing the same tune. Then again, the A14 Bionic is previous-generation technology now, and it’ll be interesting to see how the Exynos 2200 holds up against its successor, the A15 Bionic.
The AMD GPU in question appears to have 6 CUs (Compute Units) and a clock speed of 1.31GHz. It was put through the paces in three different GFXBench 3.0 runs. In the first test, dubbed Manhattan, the GPU managed to push 170 fps, putting it far ahead of the Apple A14 Bionic, which couldn’t go beyond 120 fps.
In Aztec Normal and Aztec High, the GPU managed to hit 121.4 fps and 51.5 fps, well ahead of the A14’s scores of 79.9 fps and 30 fps, respectively. Interestingly enough, the AMD RDNA2 GPU somehow managed to perform worse than a year ago. It could be due to AMD and Samsung playing around with power limits. After all, one of the main reasons for the AMD GPU’s launch was bad thermals on existing Exynos chips.
That is the main reason why it is hard to predict how well the final product will perform. Although AMD’s RDNA2 architecture is more than capable of blowing any modern-day mobile GPU out of the water, cooling it in a smartphone-like form factor is quite challenging. It all depends on Samsung’s decision to ship the Galaxy S22 series with vapor chamber cooling.
Lastly, a report suggests that not all markets will get the AMD Radeon-powered GPU in their Galaxy S22 units. The global semiconductor shortage, combined with less than ideal yields on Samsung’s 4nm node, will result in limited Exynos 2200 chipsets being manufactured.
