2019 Mac Pro: Convert RAW Files to JPEG With Adobe Camera Raw (Canon 5DS R)

MPG tested the $9399 Apple 2019 Mac Pro with 384GB OWC memory vs the top-end $3849 2019 iMac 5K 3.6 GHz Intel Core i9 8-core / Vega 48 with 128GB OWC memory. The memory difference is not a factor in this test.

2019 Mac Pro

This test is a real-world task relevant to Adobe Photoshop: batch convert raw files to JPEG. Disk I/O is not a significant factor for any of these machines.

Results: Raw file conversion to JPEG — 50-megapixel Canon CR2 raw

Part of the time required for processing Canon EOS 5Ds R lossless-compressed raw files is single-threaded only, as for all ZIP-style compression.

See the diglloyd in-depth review of the Canon 5Ds R and other Canon DSLRs in diglloyd Advanced DSLR as well as the in-depth reviews of Canon EOS R.

The 2019 iMac 5K takes almost twice as long as the 2019 Mac Pro.

The 2019 Mac Pro has 16 cores at 3.2 Ghz versus 8 cores at 3.6 GHz for the 2019 iMac 5K, yielding an expected differntial of (16 X 3.2) / (8 X 3.6) = 1.78X clock cycles ratio. And yet the Mac Pro does substantially better than that, which means some other ingredients are at play. Scalability be near perfect for starters, but it seems likely that the 3.6X greater memory bandwidth of the Mac Pro comes to bear on slowing down the iMac 5K.
