The Mongoose (Exynos M1 or possibly branded as 8890 ) has been benchmarked by the popular GeekBench. The Galaxy S6 with Exynos 7420 occa-core scores 1143 in single score and 5150 in multi-core part of the test. We ran the numbers seconds ago so they are real. The new core, expected in early 2016 phone's like the Galaxy S7 will perform much faster than that.
| Chipset | Single-Core | Multi-Core |
| Samsung Exynos M1 Mongoose – 2.3GHz | 2,294 | 6,908 |
| Samsung Exynos M1 (Mongoose) – Power Saving | 1,710 | 4,896 |
| Samsung Exynos M1 (Mongoose) – Ultra Power Saving | 1,100 | 3,209 |
| Samsung Exynos 7420 | 1,483 | 5,150 |
| Apple A9 | 2,487 | 4,330 |
The most significant is the performance gain in the single core score. This went up from 1483 to 2,294 and show a huge increase in single core performance. Samsung comes close to Apple's Flagship A9 processor when it comes to the single core performance.
The new Samsung Exynos M1 Mongoose at 2.3GHz scores 6,908 in the multi-core which is more than what the company has with its Samsung Exynos 7420. Things are looking good for Samsung as this SoC might end up at least in some models of Samsung Galaxy S7, the new phone that is expected early next year. Some versions of S7 will come with Snapdragon 820 too and it will be interesting to see how 820 is performing in the real world.
