RDNA 2’s internal display “Dianyu Renke 2077” rushed to 60 frames, Asus Zenbook S 13 OLED thin and light notebook performance measured

The Asus Zenbook S 13 OLED thin and light notebook weighs only 1KG. It is equipped with an 8-core 16-thread AMD Ryzen 7 6800U processor and a Radeon 680M built-in graphics chip with 12 sets of computing units, bringing significant game performance improvement.

Zen 3+ architecture debuts

The laptop model tested this time is Zenbook S 13 OLED UM5302, equipped with a Ryzen 7 6800U processor with Zen 3+ architecture. It adopts TSMC 6nm node process and has 8 physical cores and a total of 16 threads. The pulses are 2.7 and 4.7GHz, respectively. With the Radeon 680M built-in display chip using the RNDA 2 architecture, it has 12 sets of computing units (CUs), the highest clock can reach 2.2 GHz, and the TDP is 15~28W.

The biggest feature of this processor is to upgrade the previous generation Vega display architecture to the latest RDNA2. In addition to bringing significant display performance gains, it also supports hardware ray tracing graphics, but unfortunately it cannot support the existing Fluid Motion. Video Enhancement Technology.

Zenbook S 13 OLED has a body size of 29.67 x 21.05 x 1.49cm and a weight of only 1KG. As the name suggests, it is equipped with a 13-inch OLED panel screen with a resolution of up to 2880 x 1800, a display ratio of 16:10, and a brightness of up to 550nit. Display HDR True Black 500 certification, DCI-P3 color gamut coverage reaches 100%, and PantoneValidated color calibration certification, with Delta-E < 2 performance.

It is worth noting that in addition to one set of 3.5mm headphone and microphone composite terminals, there are also three sets of USB 3.2 Gen 2 Type-C terminals that support DisplayPort video output and Power Delivery charging functions, but the hardware part of the USB terminal supports USB 4 specification and can enable USB 4 functionality via UEFI/BIOS update in the future.

According to the documents provided by AMD, the USB 4 functions of the Ryzen 6000 series processors are quite complete, basically fully compatible with Thunderbolt 4, providing complete DisplayPort video output and PCIe Gen 3×4 transmission functions, and also compatible with Thunderbolt 3/4 Peripherals such as external devices, external graphics cards, etc.

▲ The top cover of the Zenbook S 13 OLED uses the Asus logo as the visual axis.

▲ The internal design of the fuselage will be simple, and the ultra-thin screen frame will allow the screen ratio to reach 89%.

▲ The maximum opening and closing angle of the screen reaches 180 degrees, which can be completely flattened on the desktop.

▲ The power button is partially integrated with a fingerprint sensor, which can be used with the Windows Hello function to unlock the device.

▲ The right side of the fuselage has one set of 3.5mm and two sets of full-featured USB 3.2 Gen 2 Type-C terminals.

▲ There is a set of full-featured USB 3.2 Gen 2 Type-C terminals on the left side of the fuselage. All three sets of USB ports can be upgraded to full USB 4 functionality via UEFI/BIOS update.

▲ AMD’s Zen 3+ architecture uses the TSMC 6nm node process, with an RNDA 2 architecture built-in display chip.

▲ The highest specification Zen 3+ architecture processor has 8 processor cores and 12 sets of computing units with built-in display chip.

▲ Through the improvement of hardware process and leakage of the whole platform, as well as adjustment of firmware and software, it brings more power saving effect.

▲ The Zen 3+ architecture also offers features like USB 4, PCIe Gen 4, Wi-Fi 6E, and more.

▲ A list of Ryzen 6000 series processors, this time the test object is the low-power Ryzen 7 6800U.

▲ Ryzen 6000 series processors provide full-featured USB 4, fully compatible with Thunderbolt 4, providing full DisplayPort video output and PCIe Gen 3×4 transfer capabilities. (The actual specifications of each laptop may be slightly different)

Synthesis and Processor Performance Testing

In the performance measurement part, except for the PCMark 10 storage device and battery endurance test, which was only tested for 1 round, all other test items were tested for 3 rounds, and the average was taken after confirming that there were no extreme values.

Because the author does not have the performance data of notebook computers suitable for the control group, I refer to the previous AMD Ryzen 5600G, 5700G desktop APU performance measurement data (processor part, built-in display part), and use Ryzen 5600G, 5700G test Data served as a control group and were presented graphically.

testing platform:
Laptop model: Asus Zenbook S 13 OLED UM5302 (BIOS version: 306)
Processor: AMD Ryzen 7 6800U
Memory: 16GB LPDDR5
Graphics card: AMD Radeon 680M built-in graphics chip
Storage device: Samsung MZVL21T0HCLR-00B00 1TB
Software environment: Windows 11 21H2 Home Edition, Radeon Software Adrenalin Edition 22.5.2

▲ Looking at the Asus Zenbook S 13 OLED in CPU-Z with an AMD Ryzen 7 6800U processor, the memory clock cannot be correctly interpreted.

▲ Through GPU-Z, you can see that the AMD Radeon 680M GPU has a built-in display chip with 768 sets of Unified Shaders (universal renderers).

▲ In the PCMark 10 Extended test, which reflects the overall performance experience of the computer, it is seen that the Ryzen 7 6800U outperforms the Ryzen 5 5600G, Ryzen 7 5700G and other desktop APUs, especially in game projects because of the built-in display chip of the RDNA 2 architecture and lead by a wide margin. ▲ The PCMark 10 storage device scored 1861 points, with a bandwidth of 290.93MB/s and an average access time of 88ms.

▲ In the office mode of the PCMark 10 battery life test, the Zenbook S 13 OLED can last up to 8 hours and 40 minutes with the screen brightness adjusted to the highest level, which is sufficient for all-day use.

▲ In the Cinebench R20 graphics rendering test, the single-core performance of the Ryzen 7 6800U is between the Ryzen 5 5600G and the Ryzen 7 5700G, which is quite good. The multi-core performance may be limited by TDP, so the performance is closer to the Ryzen 5 5600G that lacks 2 sets of physical cores.

▲ The Cinebench R23 graphics rendering test shows a close trend, which is an ideal performance for the power-saving U-series mobile processor.

▲ In the 3DMark CPU Profile test, the performance of the processor with different numbers of threads can be seen. It can be seen that the Ryzen 7 6800U with a TDP of only 15~28W performs tightly on the Ryzen 5 5600G with a TDP of 65W.
