SiSoftware Sandra 20/20 (2020) Released:
Brand-new benchmarks (AI/ML), hardware support

Superseded By: SiSoftware Sandra 20/21 (2021).

Updates: R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R16.

London, UK, July 18th, 2019 – We are pleased to announce the launch of SiSoftware Sandra 20/20 (2020), the latest version of our award-winning utility, which includes remote analysis, benchmarking and diagnostic features for PCs, servers, mobile devices and networks.

It adds two Neural Networks AI/ML (Artificial Intelligence/Machine Learning) benchmarks for both CPU and GP (GPU) to measure both CNN (Convolution Neural Network) & RNN (Recurrent Neural Networks) performance on modern hardware.

It also adds hardware support and optimisations for brand-new CPU architectures (AMD Ryzen 3000-series (Zen2)), (Intel “IceLake” (ICL), “CometLake” (CML)) not forgetting GPGPU architectures (nVidia “Turing”, “Pascal”) across the various interfaces (CUDA, OpenCL, DirectX ComputeShader, OpenGL Compute).

As SiSoftware operates a “just-in-time” release cycle, some features were introduced in Sandra 2017 service packs: in Sandra Titanium they have been updated and enhanced based on all the feedback received.

Operating System Module

Broad Operating System Support

All current versions supported: Windows Client 10/X, 8.1*, 7*; Windows Server 2022, 2019, 2016, 2012/R2*, 2008/R2*

Brand new AI/ML benchmarks featuring both CNN & RNN networks testing both inference/forward and training/back-propagation performance. Brand new Internet DNS and Overall Internet Score benchmarks.

Processor Neural Networks (AI/ML)

A combined performance index of CNN (inference/forward & training) & RNN (inference/forward & training) for all precisions (single/FP32, double/FP64 floating-point) and instruction sets (AVX512, AVX2/FMA, AVX, SSE4, SSE2, RTM/HLE with NUMA and large-page support)

Processor Neural Networks (Normal/Single Precision)
Processor Neural Networks (High/Double Precision)

GP (GPU) Neural Networks (AI/ML)

A combined performance index of CNN (inference/forward & training) & RNN (inference/forward & training) for all precisions (half/FP16, single/FP32 floating-point) and platforms (CUDA, OpenCL, DirectX Compute)

GP (GPU) Neural Networks (Normal/Single Precision)
GP (GPU) Neural Networks (Low/Half Precision)

About SiSoftware

SiSoftware, 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. Many worldwide IT publications, magazines and review sites use SANDRA to analyse the performance of today’s computers. Thousands on-line reviews of computer hardware that use SANDRA are catalogued on our website alone.

Since launch, SiSoftware has always been at the forefront of the technology arena, being among the first providers of benchmarks that show the power of emerging new technologies such as multi-core, GPGPU, OpenCL, OpenGL, DirectCompute, Vulkan, x64 (AMD64/EM64T), NUMA, Hybrid (big/LITTLE), SMT (Hyper-Threading), SMP (multi-threading), AVX512, AVX2/FMA3, AVX, NEON/2, SSE4.2/4, SSE2, Java and .NET.

SiSoftware is located in London, UK. For more information, please visit,, or
