Recently my asrock x570 taichi received a bios update containing agesa 1.0.8.0 and was wondering what improvements this agesa version brings.

Hopefully this is stable when they release it, I've had nothing but issues with all the BIOS revisions after the 1st one with my x570 Tomahawk.

Im not going to upgrade my bios ( Gigabyte B550) as current works perfectly fine , only when i switch to zen3

I wonder if they will ever bother doing a BIOS update for my P75 Creator 9SF. The only update for it was in January but that was a faked update, the build and date are the same as the original one. Its hard to believe that you can drop that kind of $ on a premium device and receive no BIOS update support.

I've had agesa 1.0.8.0 on my Asus C8H for about a month now and its a solid very very stable update.

The Microcode in in already supports Vermeer and some Cezanne CPUs. But not mentioned in the changelog. Interesting.

GB’s implementation of 1.0.8.1 seems rock solid for me, no problems at all.

Yeah there's still a beta going on but F30a's been good so far, unsure on the AGESA though there's a reason AMD did 1.0.8.1 over 1.0.8.0 I assume but no further specific details. Then all the non-AGESA bios bits like the various memory module timing tweaks and compatibility testing that's frequent in Gigabyte's various bios release notes and a variety of both listed and unlisted fixes for the UEFI and such itself. EDIT: Some Cezanne CPU's. Hmm maybe a work in progress from AMD then so the Ryzen 3 ready AGESA and bios rollout for the motherboards and a possible 600 series board model could be either 1.0.9.0 or another name and version restart entirely is perhaps more likely from how this works.

Going by the comments it's a small reduction but there is still a reduction to latency. 🙂 Though there's also a slightly lower boost clock speed as well from what I am reading so that could be due to the beta nature of this AGESA and bios update but that's also a thing with this update.

FYI, On 1.0.0.2 I am at 72.3ns Ref: https://imgur.com/a/GrPyqsA

and

On 1.0.8.1 70.2ns - So certainly a jump, only small but is a free bump. BUT.. CPU clocks are down for me... Like almost 100mhz down.. Never see 4.6ghz with this Agesa. Ref: https://imgur.com/a/i4L3Aeb

EDIT: Results will likely vary though and on highly tuned systems with a higher infinity fabric speed and RAM kits with optimized timings it might not make much of a difference plus if there is a reduction in maximum boost clocks the overall performance could be a bit lower though both the latency decrease and the slight decrease in clock speeds seem to me at least to be very minor. AMD will probably also tune this a bit until whatever the final variant will be called. (Version 1.0.0.0 for AMD's Zen3 perhaps on a new branch name?) That or there's more beta and WIP's and some motherboard vendors will be quick to integrate these as others wait on the more finalized versions from AMD first, probably same as usual then. (Possibly a couple of updates more quickly to AGESA and bios could also happen and further fine tuning Zen3 CPU behavior when these are out and various fixes and optimizations too.)
