GPU Performance: Synthetic Benchmarks

AMD's Rembrandt-R includes an integrated GPU update to enable it to compete against Intel's Xe iGPUs. The new RDNA2 microarchitecture is present in the Ryzen 7 7735U in the form of the Radeon 680M. With 12 CUs and 768 shader units clocked at 2.2 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 UCFF models like the 4X4 BOX-7735U, 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.

While AMD's product page for the Ryzen 7 7735U provides more clarity on the GPU's clocks, the above screenshot brings out the presence of ray tracing capabilities - a first for an integrated GPU.


AMD Radeon 680M Features

In the ray tracing department, Rembrandt-R already scores over Intel's latest iGPU. 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

The Radeon 680M has a significant edge over the iGPU in ADL-P / RPL-P, particularly at higher resolutions.

UL 3DMark

Four different workload sets were processed in 3DMark on almost all of the systems in the comparison list - Fire Strike, Time Spy, Night Raid, and Wild Life. Port Royal was also processed on the 4X4 BOX-7735U/D5 alone.

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.

UL 3DMark - Fire Strike Workloads

The graph above presents the overall score for the Fire Strike Extreme and Fire Strike Ultra benchmark across all the systems that are being compared. In both versions, the Radeon 680M outperforms the rest of the pack by a significant margin.

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 performance advantage of the Radeon 680M is again eveident in this workload.

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

This workload appears to be sensitive to the available power budget. But, even at 28W, the Radeon 680M in the 4X4 BOX-7735U/D5 is able to surpass the 40W Arena Canyon NUC.

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

As expected, this is a cakewalk for the RDNA2-based Radeon 680M.

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

With no other system capable of handling this workload, this is a lonely comparison that only shows that an increase in the power budget can deliver better performance.

    Wondering if the 4X4 Box will be updated to the Ryzen 7 7840U or any of the other Phoenix based APU's in the near future.
  • TheinsanegamerN - Thursday, April 6, 2023 - link

    Yawn. Another ryzen 6000 rebrandeon product. Nobody cares about that, we want the zen 4+rDNA3 chips.

    And why oh why do these companies always put the thunderbolt on the front? Most thunderbolt devices are left plugged in, why would I want to dirty my desk with cables wrapped around the front of the PC?

    It has all of the IO improvements relevant to this form factor. Zen 4 barely moved the needle compared to Zen 3, and RDNA3's biggest gains were in high-CU yields via chiplets. This form factor doesn't even benefit notably from the expected mild Ryzen 7x4x efficiency improvements.
  • TheinsanegamerN - Monday, April 10, 2023 - link

    20%+ increase in perf/watt, only ~5% loss going from 125 to 45 watts, and better clock scaling are "minor". Sure. Dont forget rDNA3, which is supposed to be a 40%+ improvement despite the same CU count.

    How is that rock you are living under?

    Zen 3 also scales down well, the difference is AMD wasn't advertising it.

    All of the improvements you listed are desktop 7000 platform vs desktop 5000 platform, and top SKU GPU vs top SKU GPU. Perf/watt improvements mostly came from the die shrink and improved bandwidth -- this platform has a die shrink and improved bandwidth, just the refined 6nm instead of newer 5nm. Clock scaling does not matter at these TDPs. RDNA3 performance literally cannot reach a 40% improvement over iso bandwidth (and there's no way the memory controller got completely reworked in a year's time).

    It feels like you eat up hype. Ryzen 7x4x will be nice, but its goal is to be the successor to Ryzen 5000, not Ryzen 6000. Ryzen 6000 is an up-to-date platform that has barely even stretched its legs.

    Intel in the other hand cant compete with AMD in the Sub 55W market with Zen 3+, let alone with Zen 4 ROFL.
  • meacupla - Friday, April 7, 2023 - link

    No, it's you who doesn't care.
    As it happens, this is a very fast APU, considering it is a rebranded 6000U series.
    Asrock somehow managed to tune the settings so that it is achieving extremely good results in gaming.

    As for front or rear ports, does it really matter? NUCs are best mounted on the backs of monitors anyways.
  • TheinsanegamerN - Monday, April 10, 2023 - link

    It achieves the same as any ryzen 6000 chip with DDR5. There's no magic tuning, asrock just stopped gimping.

    And yes, port placement does matter.
  • StevoLincolnite - Wednesday, April 12, 2023 - link

    No. Port placement doesn't matter on these devices. They are mounted behind monitors.
  • abufrejoval - Sunday, April 16, 2023 - link

    I own 5 NUCs, none was ever mounted to a monitor: they connect via a cascade of KVMs to a set of screens that have nothing mounted behind.

    I bought them for their low idle power and the small space they occupy under my desk. And they share that space with 6 Mini-ITX systems, four workstations and a set of semi-resident notebooks.

    While I value that at least their RAM and storage can be explanded, I'd still prefer Mini-ITX mainboards in 5L boxes, because generally they allow me to have or put anything inside (e.g. 10Gbit NICs) that I have to hang e.g. via Thunderbolt to the outside of a NUC.

    Unfortunately, getting "NUC power" in a Mini-ITX form factor has become nearly impossible, a very recent Erying G660 (https://wccftech.com/intel-alder-lake-h-laptop-cpu... which I've just added to my collection being one of the very few exceptions.

    BTW that board works rather well, at least after upgrading the Pico-PSU to 120 Watts, even if it only consumes 45 Watts on sustained peak loads.

    And thanks to a Noctua NH-L9i-17xx cooler it remains unnoticeable even under top load, something which the NUCs only ever achieve when you restrict their PL1/PL2/TAU settings to match their tiny fans.

    Just remember that personal computers have been loved for decades, exactly because people could use them in ways that their vendors never imagined.
