SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & 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. Sandra is a (girl) name of Greek origin that means "defender", "helper of mankind". We think that's quite fitting.
It 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. You can get information about the CPU, chipset, video adapter, ports, printers, sound card, memory, network, Windows internals, AGP, PCI, PCIe, ODBC Connections, USB2, 1394/Firewire, etc.
Native Unicode ports for 32-bit Windows (2000/XP/2003/Vista), 64-bit & x64 Windows (XP/2003/Vista) as well as Windows CE (Pocket PC 2002/2003/2003SE, Smart Phone 2002/2003/2003SE, CE .Net 4.20) are available.
- Benchmark UI Change: Select Multi-Threading, Multi-Core, Single-Thread
While it was always possible in Sandra to disable hyper-threading (HT) to use only physical cores/modules or disable multi-core (MC) to use only sockets/packages or just 1 thread - by using Options - we decided to make it easier to use.
So now you can test either MT, MC, ST - which can be useful on processors that use Turbo/dynamic overclocking and can boost fewer threads to higher speeds.
You can also run on all APs (application processors) - but not the BSP (boot processor, aka thread 0) just in case the BSP causes AP threads to wait for it to finish and thus delay the completion of the test (even now there are some problematic systems).
Single-thread will use an AP not the BSP as generally the BSP is loaded with other tasks (e.g. interrupts).
Note Sandra uses its own scheduler - thus does not depend on Windows to schedule the threads on specific socket/core (and perhaps park the rest). NUMA is also fully supported and the right NUMA node will be selected as appropriate for the package/core the thread should run on.
What's New in this version:
- Benchmark: GP Arithmetic
- CUDA optimisations on SM5.x hardware, up to 20% improvement in single-float.
- Benchmark: GP Scientific
- Reduced CPU check time of results on CUDA - on high-end GPUs the CPU may be fully utilised for minutes.
- Benchmark: CPU Cryptography
- Optimised x86 AES HWA code path similar to x64, up to 25-50% improvement especially on AMD hardware (e.g. Kaveri). Further updates to x64 AES HWA code path, minor 2-5% improvement.
- Benchmark: CPU Scientific:
- FFT (SFFT/DFFT) further SIMD code-path optimisations (AVX2+FMA, FMA, AVX).
- Support for Windows 10* Tech Preview
- Updated to the latest tools & libraries for forthcoming Windows 10, with various minor compatibility changes and support for new APIs, technologies as well as hardware.
- Will support DirectX 12.
- Support for very-wide SIMD AVX-512 family.
- Updated resources for high-DPI (retina+) up to 200% 192ppi or higher * e.g. huge 256x256 icons.
- Updated System benchmark: Overall Score 2015
- Removed .Net/Java Multi-Media (vectorised) benchmark as current JVM/CLR do not vectorise even today.
- Added CPU Scientific (GEMM, FFT, N-Body), CPU Financial (Binomial, Monte Carlo, Black-Scholes) Analysis * while GPGPUs do accelerate these complex algorithms, wide-SIMD (e.g. AVX-512F) can significantly accelerate them in large CPUs with many cores and large caches (e.g. 12C+ 24MB L3/128MB L4)
- Added GP Scientific Analysis (GEMM, FFT, N-Body) (using CUDA, OpenCL, DirectX Compute) * to match CPU Scientific
- Updated weights to match modern devices (mobile, laptop, desktop and server)
- Updated Crytography CPU Benchmark
- Optimised AES HWA code-path for improved performance across hardware constrained by memory bandwidth.
- Uptimised GP Benchmarks
- GP Cryptography optimised AES code-path.
- GP Scientific optimised N-Body path.
- GP Financial optimised Binomial Options path.
- Updated CPU Multi-Media (SIMD) Benchmark
- Combined score is now made of "combined integer (int32 and int64)" and "combined floating-point (single and double)" SIMD performance. Sandra 2014 used "int32 single-float and double-float" only.
- Combined integer averages int32 (32-bit integer) and int64 (64-bit integer) SIMD performance (SSE, SSE2, AVX, AVX2) * and thus measure also 64-bit integer performance that is extensively used today.
- int128 (quad-integer emulated) and quad-precision float-point (emulated, mantissa precision extended) is also measured but not included in the index as both are emulated at this time. Once native SIMD support is available in hardware, they will be added to the index.
- Updated Memory Bandwidth Benchmark
- Now reports average (rms root mean sqare) not maximum performance. Some scores will be lower depending on the hardware, usually 3-5%. You can use the "maximum value" as index if you want to match Sandra 2014 and earlier.
- Updated Cache & Memory Bandwidth Benchmark
- Now reports average (rms root mean sqare) not maximum performance. Some scores will be lower depending on the hardware, usually 5-20%. You can use the "maximum value" as index if you want to match Sandra 2014 and earlier.
- Sandra 2014 SP4
- All the fixes in 2014 and minor enhancements will be back-ported to 2014.SP4. So if you really need to stick with 2014, an update will be landing soon.

What's New in 2014:
This is a platform update release that includes tool, SDK and library updates. Overall, the benchmark scores should still be within variation range - at least on the platforms we have tested.
- Further Platform update: Windows XP, Server 2003/R2 no longer supported
In order to move forward we have to change the environment, more specifically to VS 2013; we took this "opportunity" to remove support for XP and thus Server 2003 - thus supporting Kernel 6.0 and later only.
- CUDA SDK 6.5
Now that recent WHQL video drivers support it, and due to VS2013, we changed to SDK 6.5 - which includes native Maxwell (SM50) support. Unfortunately SM10 support has been removed and SM11 support is deprecated.
- Internal Scheduler
- Fix for systems with multiple CPU groups (e.g. more than 64 threads) where affinity would be incorrect.
- Fix for benchmark failure when NUMA node would be incorrect due to above.
- Fix for benchmark lock-up when affinity would be incorrect due to above.
- CPU benchmark: Dhrystone
- Crash fix for AVX2 x64 code-path on some systems.
- CPU benchmark: Multi-Media
- Added Quad-Int (128-bit) implemented as 2x 64-bit integers or 4x 32-bit integers depending on platform.
- Added Double-Int (64-bit) SIMD AVX2, AVX, SSE4 implementation.
- CPU benchmark: Scientific
- Improved FMA FGEMM/DGEMM and FFFT/DFFT implementation.
- GPGPU benchmark: GP Processing
- Added Quad-Float (128-bit) implemented as 4x single-float (4x 32-bit) for GPUs that do not support native double-float (aka 2x 64-bit) in CUDA, OpenCL.
- Video Shader Compute
- Added Quad-Float (128-bit) implemented as 4x single-float (4x 32-bit) for GPUs that do not support native double-float (aka 2x 64-bit) in DirectX 11, 10 and OpenGL 3.x+
- Reduced OpenGL shader requirements by using extensions; lower base GL/GLSL are now supported if the extensions are supported.
