GPU Performance

GPU performance between the different devices isn’t something that you’d be able to guess just by looking at the specification sheets. On MediaTek’s side, whilst the chip in theory has 9 physical GPU cores, in this lower-binned chip variant we only see 7 of them active, at around 700MHz.

Qualcomm’s Adreno 620 is quite slower than what you’d expect from the SoC, as we saw the LG Velvet posting performance results that generally were 2.5x slower than the latest Snapdragon 865 flagship SoC.

Basemark GPU 1.2 - Medium 1440p - Off-Screen / Blit GFXBench Aztec Ruins - High - Vulkan/Metal - Off-screen GFXBench Aztec Ruins - Normal - Vulkan/Metal - Off-screen GFXBench Manhattan 3.1 Off-screen GFXBench T-Rex 2.7 Off-screen

Throughout the results, the hierarchy is quite clear, with the MediaTek D1000L chipset notably outperforming the Snapdragon 765 by up to considerable margins of up to around 50%. Both phones are doing this whilst being extremely conservative with their power usages, not exceeding 2.5-3W, and thus never getting into any thermal stress situations where they would require to throttle.

The international Reno3 devices here are really getting shafted – only posting a fraction of the performance of their Chinese counterparts. These are quite terrible results for the Imagination GPU, and in hindsight, makes their claim of a 2.5x performance increase with the new A-Series GPU look a lot less impressive – but that’s a discussion to be addressed once we actually see silicon designs with the new IP.

System Performance MediaTek clearly wins - But where are the phones?

    Back in the days MediaTek was pretty bad with drivers. What about support and optimizations now? Reply

    What's so dissapointing for the GM9446 GPU results? I can see from IMG's homepage a 2 cluster design clocked at 970MHz which performs roughly in the PowerVR Marlowe ballpark which was a 4 cluster S8 design clocked at 800MHz. If IMG's Alborix claims are close to reality, a 4 cluster design at the same frequency should be fairly close to A13 performance. Reply

    Slightly off topic question about the benchmarks. The Apple devices are well ahead in both CPU and GPU benchmarks, but my experience with 3 different current model iPads is a different story. Even my iPad Pro stutters playing minecraft, whereas my air and iPad are much slower. And battery life playing Minecraft is awful, only a few hours. Nothing like the promise that these are true PC replacements. So my question is why is there such a difference between the incredible benchmark performance and actual real world usage. Reply

    Saw some users complained about Redmi K30 Ultra for having 6-8 hours screen on time, so that's why nobody using D1000 series? Reply
