First impression: Exynos 9 (8895) in Samsung Galaxy S8 tried

In the European version of the Samsung Galaxy and Galaxy S8 S8 + (hands-on) inserted as system on a chip Samsung’s own Exynos Development 9 (8895), while the US model uses the Qualcomm Snapdragon 835 (Test). Overclockers could go to Berlin on the first touch with the Samsung chip and evaluate the clock rates.

Samsung itself has always speaks of only one variant of the Exynos 9: the model 8895th Through the rumor mill haunt but have long been two versions of the new which differ in terms of GPU 10 nm chips. The Model 8895V should be equipped with a weaker ARM Mali-G71 MP18, while the Model 8895M should be equipped with a more powerful ARM Mali-G71 MP20.

Exynos 9 (8895) uses the “GPU full expansion” ARM Mali-G71 MP20

In the European Galaxy S 8 and Galaxy S8 + infected, according to evaluation in Berlin the “GPU full expansion” of the Exynos 9 (8895) with ARM Mali-G71 MP20. Even Samsung LSI calls the ARM Mali-G71 MP20 as standard on the Exynos 9 (8895), but that is not to be equated with the fact that Samsung Mobile also uses this version. As an OEM, the components of Samsung LSI buys, Samsung Mobile could also opt for a different configuration of the system-on-a-chip in the range GPU.

GPU clocked at up to 546 MHz

In what mode range that ARM can act Mali-G71 MP20, is now firmly as well. The clock rate is, depending on strain 260-546 MHz.

Also of the timing behavior of the CPU in Berlin new insights have been gained. The four new Exynos M2 cores of performance cluster no longer seems Samsung in 2 + 2 split cores that can overclock vary. When Exynos 8 (8890) of the Galaxy S7 (test) could have two cores clocked slightly higher at up to 2.6 GHz, but all four were active, the clock was reduced to 2.3 GHz. The two faster Exynos M1 could be switched off also and convert the system on a chip for hexa-core processor.

Exynos M2 provides up to 2.31 GHz

The four Exynos M2 cores clocked in Exynos 9 (8895) between 741 MHz and 2.31 GHz, the power cluster of four ARM Cortex-A53 creates from 455 MHz to 1.69 GHz. Advanced tests with more time, however, remains to be seen whether or not it still outputs a clock boost to two of the four Exynos M2 seeds or off timer function for two cores in certain scenarios. By comparison, the Snapdragon 835 came in the test only in exceptional cases after prolonged observation of the clock behavior to its maximum clock speed of 2.46 GHz, the rest of the time were at 2.36 GHz.

Detailed analysis of the test Galaxy S8

Since both Exynos M2 and cryo should be 280 similar rapid custom implementations of the ARM Cortex-A73, the slightly higher clock rate of the Snapdragon 835 is crucial for the slightly better performance in a first performed with Geekbench benchmark 4. However, a single benchmark should not be certified too much significance, detailed measurements during the test of the Galaxy S8 are pending, also still lacks any measurements for the GPU.
