SiSoftware Sandra 2021 – the latest version of its award-winning utility. It includes remote analysis, benchmarking and diagnostic features for PCs, servers, mobile devices and networks.

SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information and diagnostic utility. It should provide most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software.

SiSoftware Sandra works along the lines of other Windows utilities, however it tries to go beyond them and show you more of what’s really going on. Giving the user the ability to draw comparisons at both a high and low-level.

Added new Overall Performance benchmarks for all major components (CPU, GPGPU, Video/Graphics, Memory/Cache and Disk) and thus simplified the Overall Computer Performance benchmark.

Also added hardware support and optimisations for brand-new CPU architectures (AMD Ryzen 2, AMD Vega GPGPU, future Intel) not forgetting GPGPU architectures across the various interfaces (CUDA, OpenCL, DirectX ComputeShader, OpenGL Compute).

SiSoftware Sandra, founded in 1995, is one of the leading providers of computer analysis, diagnostic and benchmarking software. The flagship product, known as “SANDRA”, was launched in 1997 and has become one of the most widely used products in its field. Nearly 700 worldwide IT publications, magazines and review sites use SANDRA to analyse the performance of today’s computers. Over 9,000 on-line reviews of computer hardware that use SANDRA are catalogued on our website alone.

Feature list of SiSoftware Sandra 2021:

  • Processor Overall Index. A combined performance index of all major CPU-related benchmarks: Multi-Media, Scientific Analysis, Financial Analysis, Image Processing, Multi-Core Efficiency
  • GPGPU Overall Index. A combined performance index of all major GPGPU-related benchmarks: Processing, Scientific Analysis, Financial Analysis, Image Processing, Memory Bandwidth, Memory Latency
  • Video/Graphics Overall Index. A combined performance index of all major video benchmarks: Shader Processing, Memory Bandwidth, Media Transcoding
  • Memory/Cache Overall Index. A combined performance index of all major memory and cache-related benchmarks: Memory Bandwidth, Cache Bandwidth, Memory Latency.
  • Disk Overall Index. A combined performance index of all major disk-related benchmarks: File System Bandwidth, File System I/O, Physical Disk Bandwidth
  • Overall Computer Index. A combined performance index of all component overall indexes (CPU, GPGPU, Video/Graphics, Memory/Cache and Disk)

While each benchmark measures the performance of a specific device (CPU, Memory, (GP)GPU, Storage, etc.), there is a real need for a benchmark to evaluate the overall computer performance: this new benchmark is a weighted average of the individual scores of the existing benchmarks:

  • Native CPU Arithmetic, Cryptographic, Multi-Media (SIMD), Financial and Scientific: measures native processing performance using the very latest instruction sets (AVX512, AVX2/FMA, AVX, SSE2)
  • .Net/Java Arithmetic: measures software virtual machine performance (e.g. for .Net WPF/Silverlight/Modern applications)
  • Memory and Cache Bandwidth and Latency: measures memory and caches performance
  • File System/Storage Bandwidth and I/O: measures storage performance
  • GP (General Processing) / HC (Heterogonous Compute) (GPU/APU) Arithmetic, Cryptographic, Financial, Scientific: measures (GP)GPU/APU processing performance
  • GP (General Processing) / HC (Heterogonous Compute) (GPU/APU) Memory Bandwidth and Latency: measures (GP)GPU/APU memory performance

Key features of Sandra 20/21

  • 4 native architectures support (x86, x64, ARM64** – Windows; ARM, ARM64, x86, x64 – Android)
  • Huge official hardware support through technology partners (AMD/ATI, nVidia, Intel).
  • 4 native (GP)GPU/APU platforms support (OpenCL 2.1+, CUDA 10.1+, DirectX Compute Shader 11/10+, OpenGL Compute 4.5+, Vulkan 1.0+).
  • 4 native Graphics platforms support (DirectX 11.x/10.x, OpenGL 4.0+, Vulkan 1.0+).
  • 9 language versions (English, German, French, Italian, Spanish, Japanese, Chinese (Traditional, Simplified), Russian) in a single installer.
  • Enhanced Sandra Lite (Eval) version (free for personal/educational use, evaluation for other uses)

SiSoftware Sandra 20/21-R15a Build 31.99:

  • CUDA GP-GPU Benchmarks
    • Updated to CUDA SDK 11.8 with nVidia Ada support [GeForce RTX 4090, etc.]
  • Memory Bandwidth Benchmark
    • 3-5% bandwidth increase due to L1D block/prefetch optimisations [e.g. AVX512 AMD Zen4, Intel ICL-SP, future arch.]
  • Memory Latency Benchmark
    • In-Page Random” memory access latency pattern – additional TLB ranges randomisation in addition to the randomisation within each TLB range. Credit Rob Williams @ TechGage – many thanks!
      • Benchmark now fails (does not run at all) if TLB information cannot be detected, e.g. CPU does not report it.
      • This change affects both Data and Code latencies.
    • Note that the other tests “Full Random” and “Sequential” memory access patterns – are *not* affected – as the pattern is not affected by TLB data.
    • It is always recommended to use “2MB/large” pages rather than “4kB/normal” pages in order to minimise “TLB miss” penalties which is the reason for the “in-page random” test.
  • Cryptography Benchmark
    • 3-5% bandwidth increase due to L1D block/prefetch optimisations [e.g. AVX512-VAES AMD Zen4, Intel ICL-SP, future arch.]
  • Client (GUI)
    • Light/Dark-mode colour optimisations

SiSoftware Sandra 20/21-R14c Build 31.97:

  • Memory Latency Benchmark
    • In-Page Random” memory access latency pattern – TLB range fix – that resulted in too-low memory score (latency) to be reported on modern Intel systems (e.g. AlderLake with large L3 cache).
    • Better random number generator (2^32 vs. 2^15 states) in order to defeat any possible sequence detection.
    • Note that the other tests “Full Random” and “Sequential” memory access patterns – are *not* affected as the pattern is not affected by TLB data.
    • It is always recommended to use “2MB/large” pages rather than “4kB/normal” pages in order to minimise TLB miss penalties which is the reason for the “in-page random” test.
    • Reverted to testing latencies of all cores (thus “Multi-Core”) rather than just 1 thread/core (“Single-Core”) so that on hybrid systems (Alder Lake, Raptor Lake, etc.) the average/overall latency does not favour just to Big/P cores.
  • Cryptography Benchmark
    • fixed HWA code paths (AES, SHA) not engaging [R13x regression]
  • Hardware
    • Resolved L2 & L3 cache count detection [R13x regression]
  • Client (GUI)
    • Light/Dark-mode colour optimisations
