Exynos 2100 still can't keep up with Snapdragon 888
Last updated: February 10th, 2021 at 09:09 UTC+01:00
The Exynos 2100 is a massive comeback over the Exynos 990 in terms of performance and power efficiency. Withal, it yet can't keep up with the Snapdragon 888, which appears to be a better chip overall. The folks over at AnandTech accept performed an in-depth analysis of the performance and power efficiency of the Exynos 2100 and compared it with the Snapdragon 888.
The examination involved the Exynos 2100 and Snapdragon 888 variants of the Galaxy S21 Ultra. Later performing a series of tests on both fries, it looks like Samsung's 5nm (5LPE) fabrication process offers an improvement in power efficiency to the Exynos 2100 and the Snapdragon 888 compared to their predecessors. All the same, the Southward Korean firm's best fabrication process is only as efficient as TSMC's 7nm process (N7P).
The Exynos 2100's single-threaded CPU operation turned out to exist a 27% improvement over the Exynos 990 (as opposed to 19% improvement claimed by Samsung). In terms of memory latency, the new Exynos flake fared worse than last year'due south flaghsip Exynos processor (clocking in at 136ns vs 121ns) as Samsung cheaped out on L2 enshroud for Cortex-A55 and Cortex-X1 cores. The Exynos 2100 has 512KB L2 cache for the Cortex-X1 and 64KB L2 enshroud for the Cortex-A55 cores, while the Snapdragon 888 has 1MB L2 cache for the Cortex-X1 and 128KB L2 cache for the Cortex-A55 cores.
The Snapdragon 888 performed better than the Exynos 2100 in most tasks while consuming less ability. Samsung's new processor still throttles earlier than Qualcomm's flagship, resulting in lower performance under sustained load. Even when the Exynos 2100-powered Galaxy S21 Ultra was put in a freezer while performing benchmark tests, information technology performed similar to the Snapdragon 888-equipped Galaxy S21 Ultra nether a fan. This ways that the Exynos 2100 will most likely throttle under real-earth scenarios.
The Mali-G78 GPU inside the Exynos 2100 turned out to be 40% faster than the Mali-G77 GPU used in the Exynos 990, matching Samsung'due south claims. However, information technology is only as good as the Snapdragon 865+'s Adreno 650 GPU under sustained workloads. While the Snapdragon 888's Adreno 660 GPU is better than the Exynos 2100's Mali-G78 GPU, both chips consumed a lot of ability (effectually 8W, which is bad) so throttled after a few minutes, settling around 3W.
The Exynos 2100 seems to consume 18-35% higher power compared to the Snapdragon 888. And this behaviour affects the battery life results. PCMark Work 2.0 and web browsing battery life examination shows that the Snapdragon 888 version of the Milky way S21 Ultra lasts longer on a single charge compared to the Exynos 2100 version of the phone. In fact, the chipset performed worse than the Exynos 990 Galaxy S20 Ultra in battery life tests, only that could be an anomaly.
The visitor has improved a lot compared to final year, but it still needs to work harder if it wants to defeat Qualcomm in the smartphone processor game side by side year. Samsung LSI needs to improve the CPU functioning and Samsung Foundry has to meliorate the efficiency of its 5nm procedure.
