![]() ![]() ![]() In our interviews with Travis Lanier, Gary Brotman, and Ziad Asghar from Qualcomm, we talked about the difficulties of benchmarking AI performance. #GEEKBENCH 4.3.2 DOWNLOAD SOFTWARE#Since PCMark measures system performance, it’s not surprising to see the polished Google Pixel 3 XL software slightly outperform the nearly-AOSP software on the Qualcomm Snapdragon 855 reference device.(See: 3DMark and GFXBench results sans the outdated T-Rex test.) Just as Qualcomm claimed, the Adreno 640 GPU in the Qualcomm Snapdragon 855 offers about a 20% jump in performance over the Adreno 630 GPU in the Qualcomm Snapdragon 845.The 48% and 35% improvements in GeekBench single-core and multi-core scores respectively are impressive, and since most workloads benefit from improvements to single core performance, we’ll give Qualcomm the win here. Certainly, the jump to ARM Cortex-A76-based cores should yield a substantial performance bump. Qualcomm claims a 45% improvement in CPU performance.Here are some things you should take away from the benchmark results of the Snapdragon 855 versus Snapdragon 845: Parallelization is key and these benchmarks use the DSP (in particular, Hexagon Vector eXtensions but not Tensor Accelerator). Essential operations include dot products and matrix multiplication and non-linearity functions. AImark (Ludashi)/AI BenchMark: Tests various artificial neural network (ANN) implementations.The final score weights are according to the designer’s considerations (i.e. 3DMark: An intensive graphics benchmark with tons of effects and physics that aims to stress the framerate a lot.Octane, Speedometer, Jetstream: Javascript, core language features and performance on various operations Javascript math, crypto, and search performance.The metrics are frames during test and frames per second (the other number divided by the test length, essentially), both which are specific and not some weighted score, which is really useful. Newer tests use Vulkan while legacy tests use OpenGL ES 3.1. Lots of onscreen effects and high-quality textures. GFXBench: Aims to simulate video game graphics rendering using the latest APIs.The final score weights are according to the designer’s considerations. The score breakdown gives specific metrics. Some memory workloads for latency and bandwidth are also included. GeekBench: A CPU-centric test that uses several computational workloads like compression, search, rendering, physics and ray tracing, HDR/blurring.AnTuTu tests the CPU, GPU, and memory performance, while including both abstract tests and, as of late, relatable user experience simulations (for example, the subtest which involves scrolling through a ListView).
