GPU Performance: Synthetic Benchmarks

AMD's Phoenix SoCs include an integrated GPU with a microarchitectural update over the one in the Rembrandt-R SoCs. The new RDNA3 microarchitecture is present in the Ryzen 7 7840HS in the form of the Radeon 780M. With 12 CUs and 768 shader units clocked at 2.7 GHz, AMD claims that the GPU should be capable of playing virtually any modern game at Full HD resolutions.

For full-blown desktop systems or mini-PCs targeting the gaming market, we look at gaming workloads. However, for general-purpose mini-PC models like the GEEKOM AS 6, we restrict ourselves to a series of canned benchmarks from Kishonti and Futuremark / UL. Prior to that, a look at the capabilities of the GPU via GPU-Z is warranted.


(From L to R: Default BIOS Settings, UMA Buffer Size set to 16G, UMA Buffer Size set to Auto)

Rembrandt-R's Radeon 680M had already achieved an industry-first by integrating hardware-accelerated ray tracing, and the Radeon 780M in Phoenix builds upon that. There are some improvements in the media engine too (such as AV1 encode support), but those are not revealed in the GPU-Z screenshot. The remaining subsections below look into the performance aspects.

GFXBench

The DirectX 12-based GFXBench tests from Kishonti are cross-platform, and available all the way down to smartphones. As such, they are not very taxing for discrete GPUs and modern integrated GPUs. We processed the offscreen versions of the 'Aztec Ruins' benchmark.

GFXBench 5.0: Aztec Ruins Normal 1080p Offscreen

GFXBench 5.0: Aztec Ruins High 1440p Offscreen

At 1080p, the souped-up ASRock Industrial Raptor Lake-P NUC has a slight edge of around 3% in the frame rate, but the AMD-based systems take back the crown at 1440p. The GTR7 has a 7% edge over the GEEKOM AS 6, which by itself has a 6% edge over the top RPL-P system.

UL 3DMark

Four different workload sets were processed in 3DMark - Fire Strike, Time Spy, Night Raid, and Wild Life.

3DMark Fire Strike

The Fire Strike benchmark has three workloads. The base version is meant for high-performance gaming PCs. It uses DirectX 11 (feature level 11) to render frames at 1920 x 1080. The Extreme version targets 1440p gaming requirements, while the Ultra version targets 4K gaming system, and renders at 3840 x 2160. The graph below presents the overall score for the Fire Strike Extreme and Fire Strike Ultra benchmark across all the systems that are being compared.

UL 3DMark - Fire Strike Workloads

Rembrandt-R already had an edge over RPL-P in these workloads, and Phoenix only cements this position further. The GTR7 shows a 25 - 30% improvement over the GEEKOM AS 6 behind it - a result of the microarchitectural improvements as well as higher power budget.

3DMark Time Spy

The Time Spy workload has two levels with different complexities. Both use DirectX 12 (feature level 11). However, the plain version targets high-performance gaming PCs with a 2560 x 1440 render resolution, while the Extreme version renders at 3840 x 2160 resolution. The graphs below present both numbers for all the systems that are being compared in this review.

UL 3DMark - Time Spy Workloads

The observations made in Fire Strike workloads hold true for Time Spy also. The advantage for GTR7 over the 42W Ryzen 7 7735U in the ASRock Industrial 4X4 BOX-7735U is around 25%.

3DMark Wild Life

The Wild Life workload was initially introduced as a cross-platform GPU benchmark in 2020. It renders at a 2560 x 1440 resolution using Vulkan 1.1 APIs on Windows. It is a relatively short-running test, reflective of mobile GPU usage. In mid-2021, UL released the Wild Life Extreme workload that was a more demanding version that renders at 3840 x 2160 and runs for a much longer duration reflective of typical desktop gaming usage.

UL 3DMark - Wild Life Workloads

3D Mark Wild Life was one of the GPU workloads where RPL-P's iGPU had performed better than the Radeon 680M in the Rembrandt-R systems. The GTR7's Radeon 780M wrests the crown from the ASRock Industrial NUC BOX-1360P/D5, showing a 7% increase in performance at 1440p and 17% increase at 2160p. This is doubtless due to the improved microarchitecture and higher power budget.

3DMark Night Raid

The Night Raid workload is a DirectX 12 benchmark test. It is less demanding than Time Spy, and is optimized for integrated graphics. The graph below presents the overall score in this workload for different system configurations.

UL 3DMark Fire Strike Extreme Score

The GTR7 is comfortable on top when systems with iGPUs are considered, with a 20% advantage over the GEEKOM AS 6 (which has a 20% advantage over the best that RPL-P has to offer).

3DMark Port Royal

UL introduced the Port Royal ray-tracing benchmark as a DLC for 3DMark in early 2019. The scores serve as an indicator of how the system handles ray-tracing effects in real-time.

UL 3DMark Port Royal Score

The GTR7 has a 30%+ advantage over the GEEKOM AS 6, thanks to improvements in the ray tracing engine, as well as faster iGPU clocks.

    What do you mean? "Windows is unable to present a 4K UI as a result, and the desktop resolution remains fixed at 1080p."
    Does that mean my PC monitor cannot be full 4K resolution? That's nuts!
  • ganeshts - Thursday, August 24, 2023 - link

    Please re-read the context of that statement - it is when UMA Buffer Size is set to 'Auto'. By default, it is set to 4G by Beelink. In that setting, there is no trouble outputting 4K to the monitor.

    The statement was made as a feedback for Beelink to ensure that BIOS parameters are labeled in a logical and user-friendly manner.

    I hope the Bee in the name isn't about the noise from the fan in this thing. I didn't see any mention of that but perhaps I missed it.
  • mode_13h - Saturday, August 26, 2023 - link

    Good question. STH reviewed the same unit and had fairly positive things to say about its noise profile and levels:

    Does anyone have info if it’s support external gpu?
    And is this desktop or mobile cpu? So later on the cpu can be swapped for another?
  • meacupla - Friday, August 25, 2023 - link

    It can do external GPU over USB4 or NVMe to occulink/PCIe adapter
    It's a laptop CPU, and it's not user replaceable.

    That puny fan looks like an AliExpress keychain replica of what you really wanted to order.....
    To be honest they should give you this if you pick 35W TDP and 65W should have raiser and good Noctua slim 120mm fan underneath.
    I might seriously consider this, but that fan is seriously under powered for what they put in this box.
  • meacupla - Friday, August 25, 2023 - link

    The fan might be underpowered, but the real issue is the SSD heatsink. It doesn't cover the entire length, and the pads don't make good contact with the controller.
    I don't think a 120mm would fit. 92mm slim maybe?

    I think something like an Airjet cooler would do wonders in here. Particularly with the RAM.
  • ganeshts - Friday, August 25, 2023 - link

    The lower SODIMM stick definitely needs airflow, as seen in the 10C temperature difference in our stress test.

    As for the SSD, I don't think it is much of a concern because the segment not covered by the heatsink is directly under the system fan - so it gets plenty of airflow.

    Could the thermals be better? Absolutely. But, would I trade the fan for an extended SSD heatsink? Probably not, because that would mean sacrificing airflow for the RAM (there is not much place in the internal shroud to place the fan otherwise, without affecting airflow to either the RAM or the SSD).
  • meacupla - Friday, August 25, 2023 - link

    Honestly, I think they should switch over to CAMM. Lower Z height, and don't have to worry about blocked airflow.
