Life is simpler if you go with ONE really strong single GPU like the GeForce GTX 980 Ti or TITAN X - although they (along with other NVIDIA Maxwell class GPUs) require a web based driver from NVIDIA designed for the Quadro K5000 for Mac. There are clever ways to supply power to the second GPU including routing power from the optical bay and/or stuffing a spare power supply in the lower optical bay. The main downside of dual high-end GPUs in the Mac Pro tower is that the second GPU requires an auxiliary power supply. In this shootout we used both single and dual NVIDIA GeForce GTX 980s. That can be very useful in RAM hungry apps like Photoshop. One extra benefit of the 12-core processor tray is that it has two memory banks that accept up to four sticks of ECC RAM each - thereby doubling the amount of RAM compared to the 6-core.
6 CORE MAC PRO BENCHMARKS HOW TO
When you ask me for advice on how to speed up your Mac, I usually respond by saying, "It depends on what software you're running." Sometimes the render time remains the same because the GPUs are doing all the work. And when the render time is reduced, it's not always by half even if you have twice as many CPU cores because certain pro apps use less than all available real and/or virtual cores for rendering. Some pro apps benefit from more CPU cores and some don't.
SO IS A 12-CORE MAC PRO TWICE AS FAST AS A 6-CORE? Below is the render time for the TotalBenchmark project created by Total Training. We used 'CC 2014' because it allows you to choose how many cores are used for rendering and how much real memory is reserved for each core - a feature missing from 'CC 2015', resulting in much slower render times.
6 CORE MAC PRO BENCHMARKS 1080P
On the other hand, when playing back a 1080p clip with Noise Reduction being rendered on the fly, the number of GPUs was a factor, not the number of CPU cores. Having twice as many CPU cores resulted in faster 'delivery' - but not twice a fast. Using a 5120x2160 RED clip, we asked it to 'deliver' a copy in ProRes 4444 XQ format. Note that the number of GPUs had more influence that the number of CPU cores.
Using the BruceX 5K project, we export a Master File using ProRes 4444 XQ.
( HIGHEST number of concurrent tracks = FASTEST ) Using the EvanLogic sample, we kept adding tracks until Logic Pro X 'cried uncle.' The number of concurrent tracks improved by having more CPU cores. ( LOWEST time in seconds = FASTEST )Įxporting a complex project to Blu-ray format. Essentially cuts the render time in half by have twice the number of CPU cores. We rendered the Dual BMW Benchmark (CPU version 32x32 Tiles). Compute Device set to "None" forces your Mac to render using the CPU(s) only.
