AMD Updates Chipset Driver With Support for USB4, 3D V-Cache Performance Improvements

Although not yet available directly from AMD, its latest chipset drivers, version 4.03.03.624, have been released by Gigabyte and possibly other motherboard partners and it contains a couple of interesting additions. The first one is support for USB4, albeit only for 64-bit versions of Windows 10 at this point in time. This part really only applies to the Zen 3+ "Rembrandt" mobile Ryzen 6000-series CPUs so far, as they're the only products from AMD that supports USB4 at this point in time.

The other interesting part is that AMD has included a 3D V-Cache Performance Optimizer Driver for both the 64-bit version of Windows 10 and Windows 11. As to what this driver does, is anyone's guess at this point in time, but it's likely to be some kind of cache scheduler, or possibly a means for AMD to allocate software that can't take advantage of the 3D V-Cache to the CPU native cache. We should be finding out in a couple of weeks time, as the Ryzen 7 5800X3D is scheduled for retail availability on the 20th of April.

Nice to hear of the improvements in 3D V-Cache, but does anyone have a 3D V-Cache product yet?

I believe some reviewer got the AMD Ryzen 7 5800X3D but that's might be about it.

Link: www.amd.com/en/products/cpu/amd-ryzen-7-5800x3d

I cannot find it at any online retailers in my country or on AMD.com.

You haven't asked about Ryzens specifically, so yes, you can buy an Epyc in retail.

I believe reviewers may have receive or receiving the chip. In my opinion, this is almost like the case of the big/little config used by Intel where it may take time for software to utilise the unusually big cache.

watzupkenit may take time for software to utilise the unusually big cache.
Even existing systems have a L3 cache that varies in a very wide range. If you take i3-10100 as the lower limit and R9 5900X as the upper limit, it's between 6 MB and 64 MB.

My (uninformed) guess is that software is already able to adapt to that, to an extent. Procedures for transcoding, compression or encryption can process data in smaller or larger chunks, they are probably faster with larger chunks but only as long as a whole chunk fits in the cache (most of the time, along with everything else that runs on the system).

software doesnt adapt to the cache, the cache just makes repetitive tasks faster
