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:

GPGPU OpenGL CS (Compute Shader) benchmarks

With the release of OpenGL 4.3 and OpenGL ES 3.1 compute shaders are now supported - thus we have added support for it by porting most* of the GPGPU benchmarks allowing direct comparison with CUDA, OpenCL and DirectX Compute Shader.

  • Some GPUs do not support native FP64 in OpenCL (lack compliance) but do for OpenGL and DirectX CS.
  • Android still does not officially supports OpenCL but does support OpenGL ES 3.1 and with it allows apps to use Compute Shaders.

Supported benchmarks:

  • Fractals: Float, FP64 (native/emulation), FP128
  • (emulation)
  • Crypto: AES, SHA1, SHA256, SHA512 (int64 support required)
  • Financial: Binomial, Monte-Carlo, Black-Scholes

Note: The remaining benchmarks (Scientific, Memory Bandwidth, Latency) will be enabled for SP3.

Further hardware support

  • Atom CherryTrail X7/X5
  • AMD Beema/Mullins, Carrizo, future CPU
  • XMP2 DDR4

Further software support

  • Preliminary DirectX 12 Windows 10 support

Resolved issues

  • Unable to run DirectX 11 (feature 11.0) - defaulted to DirectX 10.X instead.

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.
