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 7/8/10 32-bit
& Windows 7/8/10 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 regularly and use anti-virus software to prevent data loses and system performance degradation.

Download CUDA-Z for Linux 32-bit
& Linux 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.

Please keep in mind you can now use a 64-bit build of CUDA-Z on your x86_64 Linux to avoid 32-bit libraries installation. If you still want to use 32-bit build of CUDA-Z on your x86_64 Linux please refer to this post for more information.

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 additionally 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!
