Sandra Lite 2021 31.104

What's new in this version:

- Parallelism: All CPU/Memory Benchmarks
- Additional “Multi-Threaded big/P Cores Only” aka only using threads running on big/P cores (SMT)
- Note that as (current) LITTLE/E Atom cores do not support SMT, there is no corresponding option for them yet
- Cache & Memory Bandwidth Benchmark

Improved/fixed hybrid bandwidth workload allocation when all cores are used, e.g. on Intel 12600K:
- Memory Bandwidth Improvement: 49GB/s to 56GB/s: +14% improvement (float AVX2/buffered)
- L1D Cache Bandwidth – not affected
- L2 Caches Bandwidth fix: 145GB/s to 836GB/s
- L3 Cache Bandwidth fix: 56GB/s to 452GB/s
- Cluster Performance Contribution: All CPU/Memory Benchmarks
- It is the sum of the performance of all cores in each cluster

Reveals how much the big/P & LITTLE/E core clusters have contributed compute power wise to each benchmark score in percent, e.g. on Intel 12600K – CPU Arithmetic Benchmark:
- 80% big/P Cluster – 20% LITTLE/E Atom cluster
- Review showing these measurements: big/LITTLE cores Performance Analysis – AlderLake to RaptorLake
- Note this also works on Arm64 big.LITTLE or DynamiQ SoCs
- Core Performance Ratio: All CPU/Memory Benchmarks
- It is the ratio of the big/P Core vs. LITTLE/E core performance

Reveals just how much more performant the big/P Cores are vs. the LITTLE/E cores, e.g. on Intel 12600K – CPU Arithmetic Benchmark:
- 2.15x big/P Core – 1.x LITTLE/E Atom core
- Review showing these measurements: big/LITTLE cores Performance Analysis – AlderLake to RaptorLake
- Note this also works on Arm64 big.LITTLE or DynamiQ SoCs
