Indeed that's what seems to have happened as the Exynos 8890's GPU peaks at 650MHz versus the 770MHz frequency for the Exynos 7420. Back in November I theorized that Samsung would use the larger core implementation to lower the clocks of the GPU block and thus achieve better power efficiency. On the GPU side we knew that we'd encounter a new ARM Mali T880MP12 - the currently largest Mali implementation available among existing SoCs. If there are 3 or more cores under high load, the CPU frequency doesn't surpass 2288MHz. The catch here is that the Galaxy S7's power management doesn't allow all four cores to run at this high frequency but rather only enables the maximum clock when there's at most 2 cores loaded. This represents quite a significant boost over some past rumors which had put expectations 2.3-2.4GHz maximum frequency range. On the CPU side we find an 8-core SoC composed of 4x Cortex A53 cores running at up to 1.586GHz coupled with 4x Exynos M1 cores in a big.LITTLE configuration. The most surprising revelation was the fact that the M1 cores reach an extremely high clock of up to 2.6GHz. While by now I do have a quite good idea of what the Exynos M1 looks like, we'll be covering the topic more in-depth in a future article once we'll be able to gain better insight from our own unit for proper benchmarking and power measurements. The micro-architecture at a high level resembles ARM's big cores, but Samsung seems to have made quite a few changes and improvements when compared to ARM's designs. The Exynos 8890 employs Samsung's own designed Exynos M1 cores.
