Hi David,

Could you please give me more information on your current situation? What sort of error messages are you receiving and what are the spec of your computer. The GPU test is located in the Compute tab on the left hand side of the program. Please try to run it with all other apps closed, and your device connected to power. If the problem persists, let me know and I will look into it further.

Best,

Hello Ariella,

Thanks for the prompt and courteous reply. I’ve attached a screenshot of the GPU (Compute) image, on the windows version I can select the GPU to test, as well as the test type (OpenCL, CUDA). I am not given that option on the MAC. When I press the Run Compute Benchmark button the screen goes away and immediately returns.

Here’s a link to the CPU tests which were successfully run. https://browser.geekbench.com/v4/cpu/2040421

Thanks again,

David Young

Hello I am having the exact same issue. Was a solution found?

Also having the same issue here. The test seems to get through Sobel and then as soon as Histogram Equalization begins the test quits, but the application remains open.

I can't run it either.... it doesn't allow me to select a Compute API or a Compute Device. At the bottom of the window it says...

"No compatible compute devices found"

In my case, I'm able to click the "Run Compute Benchmark" button, but the test fails shortly afterward.

It is because of NVIDIA web drivers

Tried V 4.1. OS X El Capitan , Nvidia Web drivers (newest), CUDA drivers newest
Same, only OpenCL compute rnns well (14000 Result)
CUDA - click run does nothing, no error message, also nothing in the console log!!!
Metal (new) - same as CUDA, run does nothing, no error messagealso nothing in the console log!!!
Metal in generall works for me, no problems running some Metal benches.
Same is for CUDA. no problems.
I
I think there should be some debug code added to figure out what goes wrong.

testing a range of mac to compare, but not able to run graphics test on MBP5,5 with Nvidia 9400M (see attached screen shots) - other macs are being tested fine, so is this MBP just too old? It's not a big deal, just curious.

Hi,

Thanks for your patience, and I apologize for the delayed response.

Thanks for your report Hoy. Geekbench 4 supports Mac OS X 10.10.5 or later, and it should work fine on a MacBookPro5,5 running OS X 10.11.6. What kind of error are you experiencing? Does the benchmark start, and if so when does it stop?

Andreas and rnsjunkmail, could you tell me what model you are running the benchmark on so that we can investigate further?

Best,
Colin

It has been so long I am not sure which scenario it was.. I believe it may have been using the 2011 iMac i7 2.8GHz with 32 GB RAM running either El Capitan or Sierra

Hi,

Thanks for the information! I will pass this along and investigate as soon as possible.

Hello,

Progress, thanks. After upgrading to macOS 10.12.6 (Build 16G29), and upgrading to the latest Geekbench, and using gfxCardStatus to use the discrete GPU (nvidia GeForce gt330m), got numbers for the OpenCL workload : https://browser.geekbench.com/v4/compute/1194970 . Still not able to select the workload, or the card to test. When using gfxCardStatus to enable the integrated (Intel) adapter the Compute test immediately returns without numbers as before. Here’s the CPU tests link https://browser.geekbench.com/v4/cpu/4286868. Thanks.

Hello again, is it possible to build Geekbench with Xcode for debugging locally? thanks.

17. Support Staff Posted by Colin on 02 Oct, 2017 10:30 PM

Hi David,

By "workload", do you mean the API, or are you trying to run a Geekbench workload like Sobel in isolation? Geekbench workloads can only be run individually through the Geekbench 4 Pro command line interface.

You mentioned previously the error that appears when you clicked the Run Compute Benchmark button. What kind of error are you currently encountering which is preventing you from choosing the details of your compute test?

I'm afraid that we cannot provide a debug version of Geekbench.

Hello Colin,

1) Yes I mean the API.

2) No error or results are returned when the integrated (Intel) adapter is enabled by gfxCardStatus. The application immediately returns, no errors or results.

Thanks. Not a big issue just curious.
