Or are you saying the time it takes to process files GPU vs CPU is marginal? Because you're right about that, and that's why OpenCL should stay enabled. Here's what I'm getting with OpenCL Disabled Wait CPU goes from 177.9% to 969.9% and that's marginal? Tried it with Auto CL disabled, does appear it uses more of the CPU and processing speed difference between enabled and disabled is marginal! The system doesn't even slow down, I can still shoot, check focus and process without any noticeable slow-down, however it does feel like you could squeeze the CPU a bit further? Notice the spike at the end of the graph compared to C1 activityĪny thoughts on this? It does feel like the Mac Pro should be processing JPEG's much faster than it currently is. Here is a screenshot processing around 300 full res JPEG's (OpenCL Enabled): Only video software and fully optimized ones like JPEGmini Pro use 1200% when processing. It seems like there's a lot more room for improvement! I track my CPU performance using iStat Pro which shows all 6 cores (2013 mac pro), and during processing - either JPEG or full res tiff's, I never see C1 using 100% of each core at the same time - so 600% / 1200%.
My findings are that with CPU only, all 12 cores get maxed. I know I and a lot of others would be interested in more of this information and transparency, it's great!Įxactly. This is fantastic information, Christian. With regard to the number of cores vs clockfrequency and so on, it's a complex question, so the simplified answer will be "the more of everything (cores, clock, cache) the faster", as we can utilize all cores when processing. This prevents the system from being so loaded/saturated, that you can still work in CO and other programs.' When running on GPU's, we use the CPU for loading raw-file into RAM, and for saving/compressing the processed files to disk. ĬO uses all supported and initialized GPU's found, even different models and vendors at the same time (we have a test-machine running here with 2xGTX780 and also using the embedded HD4600 GPU at the same time) Please note that CO uses openCL, not openGL. (for me it is hexacores and 2 graphic cards), or is it only the frequency of the processors which is significant? It would be interesting to know if C1 uses all cores, and one or two graphics cards together.
To know the performance the benchmark on open gl is interesting but is one part of the performance. I don't mean to nitpick but there was no mention of 'x 1'.Ĭan you clarify whether this is an internal benchmark or something separate to C-1 entirely? 13:35:18> OpenCL : Initialization completed 13:35:18> OpenCL : Loading kernels finished 13:35:17> OpenCL Device : AMD Radeon HD 7950 Compute Engine My R270X in a 2011 Mac Pro runs as a 7950 when not flashed for Mac and pulls in at 0.11. We can use multiple GPU's but they are all benchmarked seperately, hence my "x 1".ĭoes this mean you don't take advantage of the Dual GPU's?
