Among the peculiarities of the Mac Pro 2019, the possibility of exploiting a card Afterburner, a PCIe accelerator (with a programmable FPGA or ASIC integrated) that lightens the decoding of the ProRes and ProRes RAW video codecs in Final Cut Pro X, QuickTime Player X and in the compatible apps of other developers. When purchasing the Mac Pro, the Apple Afterburner can be selected and will be pre-installed in the 5 PCI Express slots (x16) to ensure maximum performance.
Apple explains that Afterburner does not get scared even with the 8K streets, boasting the possibility of switching directly from the video camera to the timeline, and working natively with 4K and even 8K files, reducing the time of infinite conversions and also saying goodbye to proxies.
How much does performance change with the Afterbuerner? The site Barefeats he did some experiments using a Mac Pro with a 3.3GHz Intel Xeon W 12core processor (Turbo Boost up to 4.4GHz), configured with 96GB of RAM and 1TB SSD storage units.
The graphs you see here attached show the results with and without Afterburner (the red colored bars indicate the best values). Tests were performed with DaVinci Resolve 16.2 with the conversion from 8K RED to 4K ProRes 422, from 8K ProRes 4444 XQ to 4K ProRes 422, trancoding with Final Cut Pro X from 4K RAW ProRes to 4K ProRes 422, with Compressor (transcoding from 4K RAW ProRes to 4K ProRes 422), and again with DaVinci Resolve with transcoding from 8K R3D to 4K ProRes 422.
Not always the best speed with the presence of Apple Afterburner but the optimized software to exploit it actually allow to lighten the load of the processor cores leaving them free to perform more calculations, with obvious better in terms of speed.
