I'm not sure if Apple is using multi-ported RAM on their chips (in which case the seemingly small amount of RAM makes sense due to the high cost) or if they are using some fancy synchronization techniques with something a bit more "normal", but either way the idea of sharing the memory directly between the devices is perfectly reasonable, eliminating much of the need to copy blocks of data around while working.įor many users the 16 GB offering will be sufficient (even the 8 GB will work for some), but people on this forum are generally using high-end video software and are not "most users", thus the reason why Apple has only really rolled this out on their entry-level systems so far. Expensive, but it worked and it was fast (for its time). chips, but virtually everything on the system leveraged the same pool of RAM, eliminating a lot of the separate buffers that normal hardware would have. In the case of SGI they were using very expensive multi-ported RAM external to the CPU/GPU/etc.
There is nothing inherently wrong with the shared memory concept it is essentially a repackaging of the same thing SGI was doing with the Unified Memory Architecture on their O2 series workstations some years ago.

You'll loose the Render cache, but you should have about 30% more memory available without Resolve. You'll clear some overhead from the rest of resolve and gain a little stability. If you are using Resolve Studio, you might want to use Fusion Studio (the standalone version) instead. Resolve and Fusion Studio do have known issues (or at least many reports) with clearing VRAM.Įdit: in that case you should prepare a bug report for Blackmagic, including a Resolve log. That being said, if you are playing the clip fine on loop and suddenly it stops because the memory is full, then this could potentially show a memory leak, or memory clearing issues. Minimum specs for Fusion are usually 32GB RAM. You might want to watch out as there have been reports of SSDs quickly deteriorating in the new M1 macs because they have to use the SSD very quickly for memory. It's incredible that the system is able to load so much/ so fast onto the SSD in the first place.
