Sandra 20/20 (2020) Press Release

Latest Sandra Version

We are moving towards a tiered system where different versions (R numbers) are provided to different customers depending on their need and version type. This allows us in these tough times to prioritise our customers while still providing stable, best features to the community. We will still aim to release all versions together where possible but we no longer guarantee it.

  • Manufacturers/OEM, Tech Support, Reviewers:
    • Latest Sandra (Beta) version, R+1
  • Commercial (Professional/Business/Engineer/Enterprise):
    • Current Sandra (Stable) version, R (R+1 if required*)
  • Lite (Evaluation):
    • Previous Sandra (Stable) version, R-1

Note (*): we will provide access to Beta versions if customer is affected by an issue resolved in the next release.

GP-GPU (CUDA / OpenCL / DirectX Compute) Benchmarks

  • Additional performance improvements for nVidia “Ampere
  • Additional performance improvements for “Image Processing” Benchmarks
  • Relaxed limits further for better performance on high-end/multiple GP-GPUs [up to 8]

CPU Benchmarks

  • Fixed possible lock-up in “Scientific Analysis” Benchmarks
  • Revised benchmarks for asymmetric work-loads for hybrid CPUs

Bug Fixes

  • Fixed (possible) crash on Intel graphics with 64-bit PCIe memory addressing
  • Reviewed all device code that deals with 64-bit PCIe memory addressing
  • Fixed TigerLake (TGL) memory information/timings for (LP)DDR5
  • Fixed TigerLake (TGL) integrated graphics memory information
  • Additional IceLake (ICL) memory information

SiSoftware Sandra 20/20/9 (2020 R9) Update – GPGPU updates, fixes

Update Wizard

We are pleased to release R9 (version 30.69) update for Sandra 20/20 (2020) with the following updates:

Sandra 20/20 (2020) Press Release

GPGPU Benchmarks

  • CUDA SDK 11.3+ update for nVidia “Ampere” (SM8.x) – deprecated SM3.x support
  • OpenCL SDK updated to 1.2 minimum, 2.x recommended and 3.x experimental.
  • Increased addressing in all benchmarks (GPGPU Processing, Cryptography, Scientific Analysis, Financial Analysis Image Processing, etc) to 64-bit for large VRAM cards (12GB and larger)
  • Increased limits allowing bigger grids/workloads on large memory systems (e.g. 24GB+ VRAM, 64GB+ RAM)
  • Optimised (vectorised/predicated) some image processing kernels for higher performance on VLIW GPGPUs.

CPU / SVM Benchmarks

  • Vectorised CPU Multi-Media 128-bit integer benchmark to support ADX/BMI(2) instructions as well as vectorised to support AVX512-IFMA(52) (52-bit integer FMA, 104-bit intermediate result) on Intel “IceLake” and newer CPUs (also supporting AVX512-DQ, AVX2 and SSE4). See “AVX512-IFMA(52) Improvement for IceLake and TigerLake” article.
  • Optimised .Net and Java Multi-Media 128-bit integer benchmarks similar to CPU version.
  • Increased limits/addressing allowing bigger grids/workloads on large thread/memory systems (e.g. 256-thread, 256GB RAM)

Bug Fixes

  • Fixed incorrect rounding function resulting in negative numbers displayed for zero values(!) Display issue only, actual values not affected.
  • Fixed display for large scores in GPGPU Processing benchmarks (result would overflow the display routine). Display issue only, scores stored internally (database) or sent/received from Ranker were correct and will display correctly upon update.
  • Fixed (sub)domain for Information Engine. Updated microcode, firmware, BIOS, driver versions are displayed again when available.
