👁 Embree benchmark with settings of Binary: Pathtracer ISPC, Model: Asian Dragon Obj. m8a.8xlarge was the fastest.

👁 OSPRay Studio benchmark with settings of Camera: 3, Resolution: 4K, Samples Per Pixel: 16, Renderer: Path Tracer, Acceleration: CPU. m8a.8xlarge was the fastest.

👁 OSPRay Studio benchmark with settings of Camera: 1, Resolution: 4K, Samples Per Pixel: 16, Renderer: Path Tracer, Acceleration: CPU. m8a.8xlarge was the fastest.

Creator workloads like rendering with OSPRay Studio were also showing very nice render time improvements out of these new AMD EPYC 9R45-backed instances.

👁 Timed Erlang/OTP Compilation benchmark with settings of Time To Compile. m8a.8xlarge was the fastest.

👁 Build2 benchmark with settings of Time To Compile. m8a.8xlarge was the fastest.

👁 Timed LLVM Compilation benchmark with settings of Build System: Ninja. m8a.8xlarge was the fastest.

👁 Timed Linux Kernel Compilation benchmark with settings of Build: allmodconfig. m8a.8xlarge was the fastest.

👁 Timed Linux Kernel Compilation benchmark with settings of Build: defconfig. m8a.8xlarge was the fastest.

👁 Timed ImageMagick Compilation benchmark with settings of Time To Compile. m8a.8xlarge was the fastest.

👁 Timed Godot Game Engine Compilation benchmark with settings of Time To Compile. m8a.8xlarge was the fastest.

👁 Timed FFmpeg Compilation benchmark with settings of Time To Compile. m8a.8xlarge was the fastest.

For those considering Amazon M8a instances for code compilation / build farms / CI / CD type purposes, there was very nice build time savings going from M7a to M8a. In turn much better value too moving up to the AWS M8a instances.

👁 7-Zip Compression benchmark with settings of Test: Compression Rating. m8a.8xlarge was the fastest.

👁 7-Zip Compression benchmark with settings of Test: Decompression Rating. m8a.8xlarge was the fastest.

Very solid generational performance improvements from M7a to M8a AWS instances, just as we saw too going from EPYC 9004 to EPYC 9005 in the many bare metal performance benchmarks over the past year.
