Samsung to Use AMD’s RDNA 2 Graphics Across 20 Galaxy Smartphone Models [Rumor]

In keeping with the most recent rumors, Samsung is planning to leverage AMD’s RDNA 2 graphics IP throughout 20 totally different smartphone fashions. Whereas the Exynos 2200 can be used to energy the high-end Galaxy S22 lineup, there can be a number of lower-end SKUs that can even characteristic cut-down variants of AMD’s RDNA 2 cell GPU. These ought to be significantly quicker than the Mali/Adreno graphics utilized by most finances and higher-end Android smartphones.

In keeping with rumors, poor 4nm yields imply that solely half of all Galaxy S22 smartphones shipped will characteristic the Exynos 2200, with the remainder packing Qualcomm’s Snapdragon 898. Which means that the RDNA 2 GPU would solely find yourself in gadgets promoting Europe and Russia, with American and Asian patrons getting its Adreno counterpart.

As per the Korean outlet TheElec, Samsung will use the Exynos 2200 and RDNA 2 graphics not just for the Galaxy S22 but additionally for the S22 Fan Version (solely), S21 Fan Version, the Galaxy S8 Tab, S8 Plus, and S8 Extremely.

Earlier protection:

In keeping with rumors (an official benchmark), the Exynos 2200 is 31-34% quicker than its predecessor at peak efficiency whereas dropping to 17-20% in sustained workloads. This result’s actually a bit underwhelming in comparison with all of the earlier leaks that we’ve seen and seems to be restricted to a single software or benchmark. The GPU appears to be affected by a good bit of throttling on extended use. It’s unclear whether or not the retail {hardware} can have the identical problem or not.

The supply claims that the (GPU) efficiency distinction between the Snapdragon 888 and the Exynos 2200 is kind of large whereas not revealing the precise numbers. Final, however not least, it’s necessary to notice that these figures are from pre-release {hardware} and drivers, and the ultimate figures will possible be a bit larger.

Within the newest spherical of exams, the Exynos SoC meant for the Galaxy S22 has gotten a GOS (Recreation Optimizing Service) uplift, assuaging throttling when the service is enabled. It’s value noting that GOS limits the max enhance clock to roughly 50% of the general frequency, but it surely’s nonetheless extra performant than the throttled clocks. The mRDNA GPU on the Exynos 2200 is presently being examined with a lift clock of 1.29GHz. With GOS, the max clocks drop to 600-700MHz, however these figures are nonetheless larger than earlier exams the place the GPU would throttle to 30% of its peak clock.

AMD’s cell RDNA 2 GPU is able to critically excessive clock speeds. For the time being, the engineers are testing two variants of the Exynos 2200 SoC: one with the GPU core clock set to 1.29GHz, and the opposite to 1.58GHz. The catch is that with the latter, the CPU clocks (of the center cores) should be tuned down a bit to maintain the TDP in verify:

The supply claims that the height GPU rating with the 1.58GHz variant is healthier because of larger retention even after throttling. It seems to be just like the RDNA 2 structure is able to excessive enhance clocks whatever the course of node. In keeping with the most recent rumor, the cell RDNA 2 design Samsung is utilizing is able to a whopping 1.8GHz with the TDP set to 10W.

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

The graphics processor built-in into the cell SoC in partnership with AMD options 6 CUs, with an working (enhance?) clock of 1.31GHz. The processor was benchmarked (2nd spherical) in GFXBench, and the next scores have been noticed:

Manhattan 3.1: 170.7 FPS

Aztec Regular: 121.4 FPS

Aztec Excessive: 51.5 FPS

The GFXBench figures from the third spherical of the graphic throttling exams are as follows:

Manhattan 3.1: 127.5 FPS

Aztec Regular: 90.7 FPS

Aztec Excessive: 39.65 FPS

Along with Samsung, Google and some Chinese language smartphone markers are additionally (reportedly) engaged on implementing RDNA 2 IP of their gadgets. It’s finest to take the latter with a grain of salt because it’s the primary we’re listening to of it. The Exynos 2200 SoC paired with the RDNA 2 (codenamed Voyager) GPU can be fabbed on the foundry’s 4nm LPE node. It’ll characteristic 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.
