it’s in this article as well "… AMD’s 3D V-Cache can be even faster when used for its intended purpose. First-generation 3D V-Cache is good enough for a 2 TB/s peak throughput, AMD states, while data bandwidth is even higher (2.5 TB/s) on the second-generation variant of the technology…
even losing 90% of it’s peak throughput is still good for .182TB/s and while the peak numbers came up using a 16/32MB dataset on a 96 MB drive , the tech was still able to pull a READ of 111k MB/sec and WRITE of 50k using an 8GB dataset on the same 96MB partition - the author called the results ’ puzzling ’

(answered twice because reddit automod removed first post for linking to twitter where the results were posted. if you want to see it, twit handle is GPUsAreMagic)

READ 182,923 MB/sec / WRITE 175,260.

The fastest PCIE 5.0 PCIE NVME SSD drives currently run around 12,500 /11,800 read/write so call it an order of magnitude faster (10x) + 50%.

They used OSFmount to create the ramdrives.
