Actually, that looks very good for the small i7, but it really only measures RAM and CPU. Neither your slow Fusion drive or your video card (on chip) are reflected in the top two numbers. I’ve never had a Fusion drive (except to separate it on a new iMac), so I don’t know it’s speed range. But even a SATA SSD can’t get to 600MB/s, and the NVMe blades are about 500% faster which are stock in the current iMacs. The other issue, as you pointed out, is the video card. VRAM with OpenCL or Metal is very important with all the non-compressible files with raster imagery. The problem is twofold. First of all, the “VRAM“ is being stolen from your RAM, which is very weak compared to actual VRAM which is in the card and is 2 generations faster than RAM. The second problem is that they never give you enough to make a big difference. From testing, it appears to me that OpenCL only just gets going with 1GB, but gets a lot better with 2 or more GB. So, without adding a video card, you are stuck with little help to get through a photo edit.As in signature, late 2015 21.5" 4K iMac, 3.3GHz quad i7, 2TB Fusion/16GB/1GB Intel GFX.

Hi Chris,I believe the 2TB Fusion drives have more SSD space (128GB) and spin at 7200rpm, so that helps a bit compared to a slower 5400rpm drive. An NVMe blade would be nice, sure, but my 2TB minimum storage requirement makes it an expensive option unless I want to crack open my iMac myself (could, and have, but won't again).
The computer does well for my typical use cases, which are primarily high-res music AirPlay-ing, 4K Plex streaming, the occasional Photoshop file and some light gaming. My next iMac will likely be a 27" so I can have a dedicated graphics card again and keep 2TB+ of storage (no longer offered on a 21" in any config, baffling). Aiming for 4GB VRAM next time, too. We'll see what the rest of 2020 holds. I've got a major case of FOMO but a new iMac is very tempting.
Fingers crossed SSD's are the only option in the future and are relatively affordable. I use Fusion only because I have to, currently.Hi Chris,
I don’t believe Fusion drives will be around too much longer if macOS stays on its current track of eliminating HDDs...
