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

Windows Defender Core Isolation features and Sandra’s Kernel Driver
Sandra is compatible with most “Core Isolation” security features and you can have those enabled:
- Memory Integrity – Compatible, can enable
- Memory Access Protection – Compatible, can enable
- Microsoft Vulnerable Driver Blocklist – Kernel driver compatible
- Kernel-mode Hardware-enforced Stack Protection – Kernel driver not compatible, but software will still run with reduced functionality
CPU Multi-Media Benchmarks
- AVX-iFMA(52): New 256-bit code path based on AVX512-iFMA(52) 512-bit for future arch (e.g. “Meteor Lake” MTL, “Arrow Lake” ARL). We saw +66% improvement as detailed in our AVX512-iFMA(52) Improvement for IceLake and TigerLake article.
- AVX512-FP16: New code path for Xeon processors that support AVX512-FP16. We expect +90% improvement over FP32 if precision loss in acceptable (e.g. zoomed out fractals).
Note: Future FP16 code-paths will also be added to the other CPU benchmarks, however some parts may remain FP32 as the loss of precision would make the results useless. We have explored this in our GP-GPU article dealing with FP16 support: FP16 GP-GPU Image Processing Performance & Quality.
CPU Cryptogaphy Benchmarks
- SHA2-512 HWA: Hardware-accelerated hashing SHA512 code-path – based on current SHA2-256 HWA. We expect ~3x (three times) better performance based on the SHA2 non-accelerated/HWA results.
- Future SM3-256 (China) HWA: Hardware-accelerated hashing SM3 code-path (China’s version of SHA hashing functions). We expect similar performance improvement to SHA HWA.
- Future SM4-128/256 (China) HWA: Hardware-accelerated block crypto SM4 code-path (China’s version of AES block crypto functions). We expect similar performance improvement to AES HWA.
Note: We will default to “SM4 + SM3” benchmarks – rather than “AES + SHA” for both CPU & GP-GPU Cryptography benchmarks when “China” locale is detected as these algorithms are more likely to be used there.
Note 2: ARM already includes SHA2-512, SM4, SM3 HWA (hardware acceleration extensions) in their high-end cores.
Note 3: While AES & SHA are not going anywhere, there has been a shift to other crypto-algorithms (especially those that can encrypt/decrypt and hash/authenticate like “ChaCha20Poly1305” as famously used in WireGuard VPN) that are fast enough even without hardware acceleration!
All CPU Benchmarks – AVX10 Support
- AVX10.2+ 256-bit future code paths (FP32, FP64 and FP16) for Hybrid architectures (e.g. “Meteor Lake” MTL, “Arrow Lake” ARL). Note both Core (P) and Atom (E) will run the same 256-bit width binary and not different widths
- AVX10.1+ 512-bit & AVX512 shared code path (FP32, FP64 and FP16) for Xeon architectures
- Possible AVX10.2+ 128-bit future code path for Atom/Other discrete architectures if required
Note: in future Hybrid arch, Core (P) cores are likely to support 128/256-bit widths only. We don’t know (and we could not tell you) whether disabling Atom (E) cores will get the Core (P) to report 512-bit widths.
- Intel 14th gen Hybrid “Raptor Lake Refresh” RPL-S support
- Intel future gen Hybrid “Meteor Lake” (MTL-S/M/P/N), “Arrow Lake” (ARL-S/U), “Lunar Lake” (LNL-M) detection
- Intel future gen Xeon “Granite Rapids” SP/D detection
