7nm fabrication: Exynos 9825's Touch 10 maintains GPU performance at continuous load

7-nm-Fertigung: Exynos 9825 des Note 10 hält GPU-Leistung bei Dauerlast

In Galaxy Note 10 tinkers with the Exynos 9825 a new system-on-a-chip, which was previously not found in the Galaxy S10. In addition to a minimal clock adjustment, a more efficient 7 nm manufacturing process is the biggest change. In the stress test, the chip keeps the performance at a high level, especially in the area of ​​the GPU.

Samsung's annual schedule for smartphones and new system-on-a-chips usually follows the same pattern: new top SoC and Galaxy S in the spring, new Galaxy Note with the same SoC in late summer. At Note 10 (Test) this is different, because for the first time the Exynos 9825 has its own SoC for the note.

From 8 nm LPP to 7 nm LPP EUV

For the Exynos 9825, Samsung has switched from the 8 nm LPP production of the Exynos 9820 to 7 nanometers LPP plus EUV. The EUV exposure is used for some layers of the chip. The new manufacturing process reduces the die size at which Samsung, with 127mm² from the 8nm production of the Exynos 9820, has been outnumbered by the TSMC's Snapdragon 855 7nm process. In addition, an improvement in energy efficiency is to be expected, although Samsung was presented at the start of the 7-nm production last October, only a reference to the old 10LPE process, which should be at 50 percent.

Galaxy Note 10+ in the stress test

What this means in practice, ComputerBase wanted to find out based on the Galaxy Note 10+ and a stress test for GPU and CPU to determine whether the new processor has the same performance losses as the on paper inefficient Exynos 9820 in the S10, in all three variants of the smartphone after a short time could no longer provide the full power.

GPU performance is now consistently high

In the GPU Throttle Test (GFXBench Manhattan 3.1 1080p Offscreen), the Galaxy Note 10+ excellently holds an image refresh rate between 72 FPS and 73 FPS, consistently delivering maximum performance without getting warmer than 43 degrees Celsius on the back. Similarly, only the OnePlus 7 Pro (test) and the Asus ZenFone 6 (test), which got quite warm in this test, have done well. Both are equipped with Qualcomm's Snapdragon 855. The Galaxy S10 series, however, rose with 69 FPS and dropped from the fifth round up to 55 FPS.

The fact that the Galaxy Note 10+ performs better, the smartphone has certainly also owed to its compared to the S10 + slightly larger housing, but a portion of the success may also be attributed to the new Exynos 9825.

Cortex-A75 clock higher

The conclusion to the CPU is less euphoric. Here, Samsung has raised the clock rates of the two ARM Cortex-A75 from 2.31 GHz to 2.40 GHz. This measure does not result in noticeably more performance in everyday life, although a small plus can be noted in the benchmarks. Surprisingly, however, the Galaxy Note 10+ shows a completely different behavior under CPU continuous load in Geekbench 4.

Massive burglary, erratic rise

In the single-core and multi-core test, the Exynos 9825 initially keeps its performance at a high level for a little longer. The temperature-related throttling then begins but surprisingly intense, so that the performance falls below any previously measured smartphone with Exynos 9820 or Snapdragon 855. In the single-core test it is up to 44 percent, in the multi-core test up to 81 percent of the output power. The Exynos 9820 buckled earlier but less dramatically.

Performance marginally higher towards the end

Once the processor recovers, the single-core performance jumps back to its original level, only to drop back to 76 percent before the game repeats. In the multi-core test, the original result is no longer achieved, but also here on the downside better results in the interplay with not so very dramatic slumps. Interestingly, however, the performance in both cases after the first break above the Exynos 9820.

Note 10 series sells well

Although Galaxy Note 10 and Galaxy S10 are very similar in many functions, the Stylus smartphone sold in the native country of South Korea excellent. One million units were sold in the first 25 days after market launch, the news agency reported Yonhap, That was twice as many devices as the Galaxy Note 9 Galaxy S8 had needed for a million units 37 days.
