Samsung Exynos 2200 w/ AMD RDNA 2 Graphics to be Announced on 19th November [Update]

Samsung is all set to announce its next-gen Exynos 2200 SoC next week with a special focus on gaming. The company’s official IG account states: Gaming has come a long way. What we used to deem “immersive”, relied on a slew of external factors, like the surrounding environment. But the advancements of semiconductors have changed that- learn how, when we move to our new home on Nov. 19th. Stay tuned, #EverythingChanges.

Update: Looks like the Exynos 2200 won’t be launching on the 19th after all.

Considering that the company’s next-gen Exynos 2200 SoC will leverage AMD’s RDNA 2 graphics IP, we can be sure that a lot (if not everything) will change with this next announcement. In the latest round of tests, the Exynos SoC meant for the Galaxy S22 has gotten a GOS (Game Optimizing Service) uplift, alleviating throttling when the service is enabled. It’s worth noting that GOS limits the max boost clock to roughly 50% of the overall frequency, but it’s still more performant than the throttled clocks.

The mRDNA GPU on the Exynos 2200 is presently being tested with a boost clock of 1.29GHz. With GOS, the max clocks drop to 600-700MHz, but these figures are still higher than previous tests where the GPU would throttle to 30% of its peak clock. The RDNA 2 GPU is capable of seriously high clock speeds. Two variants of the Exynos 2200 SoC have been in development: one with the GPU core clock set to 1.29GHz, and the other to 1.58GHz. The catch is that with the latter, the CPU clocks (of the middle cores) have to be tuned down a bit to keep the TDP in check:

The peak GPU score with the 1.58GHz variant is reportedly better due to higher retention even after throttling. It looks like the RDNA 2 architecture is capable of high boost clocks regardless of the process node. According to the latest rumor, the mobile RDNA 2 design Samsung is using is capable of a whopping 1.8GHz with the TDP set to 10W.

The scores of the mobile GPU in GFXBench are as follows:

The graphics processor integrated into the mobile SoC in partnership with AMD features 6 CUs, with an operating (boost?) clock of 1.31GHz. The processor was benchmarked (2nd round) in GFXBench, and the following scores were observed:

Manhattan 3.1: 170.7 FPS

Aztec Normal: 121.4 FPS

Aztec High: 51.5 FPS

The GFXBench figures from the 3rd round of the graphic throttling tests are as follows:

Manhattan 3.1: 127.5 FPS

Aztec Normal: 90.7 FPS

Aztec High: 39.65 FPS

Even though there’s still a fair bit of throttling, the device remains nearly 50% faster than the Apple A14 in graphics workloads and considerably ahead of the Exynos 2100. The source believes that the mid-range SoCs will be paired with 2-4 CU GPUs, with a core clock of around 1GHz. The lower-end Exynos SoCs will be paired with Cortex A78 cores on the CPU side. Since it’s a much smaller chip, throttling isn’t really an issue.

The Exynos 2200 SoC paired with the RDNA 2 (codenamed Voyager) GPU will be fabbed on the foundry’s 4nm LPE node. It’ll feature eight CPU cores: x1 Cortex-X1 high-performance core, x3 Cortex-A78 medium cores, and x4 A55 low-power cores. The SoC is slated for a launch in December 2021. As such, an announcement in late November makes a lot of sense.
