Samsung Galaxy S23 Ultra benchmarks – Snapdragon 8 Gen 2 for Galaxy examined
This year, it finally happened that the new Galaxy S series runs a single SoC across the globe. No more Exynos versions, just Snapdragon. But that doesn’t mean the new Galaxy S23 series doesn’t stand out from the crowd. The Snapdragon 8 Gen 2 running under the hood of all S23 phones is actually “Snapdragon 8 Gen 2 for Galaxy”.
This is because both the CPU and GPU are overclocked and offer slightly higher performance than the other phones with the same chipset in the market. But how much of a difference does it make?
The SD 8 Gen 2 for Galaxy has the same CPU configuration with 1x Cortex-X3, 2x Cortex-A715, 2x Cortex-A710 and 3x Cortex-A510 cores, but the primary Cortex-X3 core is clocked at 3.36GHz instead of 3.2GHz. The same applies to the GPU – the Adreno 740 here runs at 719 MHz instead of the usual 680 MHz.
But without further ado, let’s dive into the early benchmarks. In particular, we have only chosen phones with 1440p screens where possible, so that we can get more comparable results in the on-screen graphics tests.

The results from the Geekbench 5 CPU test may come as a surprise to some, but there is a perfectly good explanation why the Galaxy S23 Ultra takes the lead over the nubia Red Magic 8 Pro in the single-core test and falls behind the latter in the multi-core scenario. First, the Cortex-X3 inside the S23 Ultra is clocked higher, and second, the large Cortex-X3 core is not used in the multi-core test. And that’s why the Red Magic 8 Pro may have a slight advantage over the Galaxy due to its powerful cooling system that allows the Snapdragon 8 Gen 2 to run in a higher gear. Still, the difference is quite small.

In the AnTuTu test, the Galaxy S23 Ultra falls behind the Red Magic 8 Pro because the latter has a 1080p+ display that requires less processing power to run the test. After all, AnTuTu 9 is a composite test. However, the Galaxy S23 Ultra has a clear advantage over the OnePlus 11, which runs the same chipset and a 1440p+ screen. The higher clocked CPU and GPU pay off.
The new Snapdragon is also significantly faster than the older Snapdragon 8+ Gen 1 chip and even the A16 Bionic inside the iPhone 14 Pro Max.

When it comes to GPU-intensive tasks, the Galaxy version of the Snapdragon 8 Gen 2 is a clear winner. In almost all off-screen tests, the Galaxy S23 Ultra took the lead over the rest, falling short only in the on-screen tests when challenged by lower-resolution phones.
All in all, the new Galaxy S23 series offers a significant upgrade over its predecessors, regardless of version. But European and Indian consumers are likely to benefit the most as the Snapdragon 8 Gen 2 for the Galaxy blows last year’s Exynos 2200 SoC out of the water.
To put things into perspective, the Galaxy S23 Ultra is 30-35% faster than the Galaxy S22 Ultra in the CPU tests and about 30% faster in the combined AnTuTu 9 benchmark. Across the GFX Bench and 3DMark GPU tests, the Galaxy S23 Ultra showed a whopping 2x performance boost at times, but in most scenarios it’s an 80-90% improvement.

In addition to the already excellent synthetic performance, the Galaxy S23 series also boasts improved cooling capabilities, which was an issue for some users in the past. But you may have to wait for our full review of the trio to come out to find out how well the new cooling works in practice.
