Get your CUDA-Z >>>

This program was born as a parody of another Z-utilities such as CPU-Z and GPU-Z. CUDA-Z shows some basic information about CUDA-enabled GPUs and GPGPUs. It works with nVIDIA Geforce, Quadro and Tesla cards, ION chipsets.

CUDA-Z shows following information:

  • Installed CUDA driver and dll version.
  • GPU core capabilities.
  • Integer and float point calculation performance.
  • Performance of double-precision operations if GPU is capable.
  • memory size and bandwidth.

This program also exports collected information to HTML format and plain text file.

Download CUDA-Z for Windows XP/Vista/7/8 32/64-bit

Windows notes:
CUDA-Z is known to not function with default Microsoft driver for nVIDIA chips. User must install official driver for nVIDIA products to run CUDA-Z.

It's strongly recommended to update your Windows regulary and use antivirus software to prevent data loses and system performance degradation.

Download CUDA-Z for Linux 32/64-bit

Linux notes:
CUDA-Z is known not to function with 3rd-party linux driver for nVIDIA chips. You can download the official driver from nVIDIA website if your distribution is not equipped with proper driver.

Note also that x86_64 linux requires 32-bit compatibility libraries package being installed to run CUDA-Z. (sudo apt-get install ia32-libs for Ubuntu x86_64). In case of problem with available package you can download the source archive and follow instructions in readme.txt.

Download CUDA-Z for Mac OSX

Mac OSX notes:
CUDA-Z runs in Mac OSX 10.8 and later. Macs a shipped with proper Geforce driver but CUDA driver is not, so CUDA-Z additionaly requires special CUDA Drivers for MacOS being installed in the system.

As far as CUDA 6.0+ supports only Mac OSX 10.8 and later the new version of CUDA-Z is not able to run under Mac OSX 10.6. For those who runs earlier versions on their Mac's it's recommended to use CUDA-Z 0.6.163 instead.

Please note that CUDA-Z for Mac OSX is in bata stage now and is not acquires heavy testing.

Q: What should I do if CUDA-Z finds no CUDA?

A: Either you have no supported nVIDIA hardware or not supported OS or you have no proper driver installed. First check if your hardware is CUDA-enabled. If the hardware is OK, try to update your driver. It might be you have either limited nVIDIA driver or 3rd-party driver that not capable to run CUDA code.

Q: Ooooooops! CUDA-Z crashes.

A: Report a bug. I'll take care of it as fast as I can.

Q: I have a question...

A: Ask it in the forum. You are always welcome! :-)

Q: Gimme code!
