The performance here is less interesting than the apparently quasi imminent availability of real RVA23 devices. If/when that occurs it will set a baseline and things should not warrant from scratch rebuilds constantly for at least a while.
Anyone that believes semiconductor performance claims before device availability is in for a rough time.

High performance for RISC-V; still a ton of catchup especially in efficiency (perf/W) to Intel/AMD and Arm.
At least we're getting close to Raspberry Pi level performance now.

Can't wait for a faster risc-v SBC, waiting for rust builds on my VisionFive 2 drives me crazy.

Reminder: Haswell and Zen1 were around 8.1 specint2006/GHz.
These CPUs are above that.

So is P550 ... 8.65 is the claim I think. It doesn't have the MHz though. My i7-4790K (which is still in the back room somewhere) had a base of 4.0 GHz and could turbo to 4.2 or 4.4. My Megrez is doing just 1.8 GHz.

Main issue with P550 is no V. Huge handicap, can't easily make up for that.
RVA23 requires V. These incoming CPUs are the real deal, a perfectly usable performance level in the present day.
(unless they cache-starve them or some other such fuck up)
My 4790k was still my main PC until I recently (weeks) built a new PC with 9800x3d, 96GB ECC, rx7900gre.
4790k had 4 cores. If these new chips clock reasonably, say, 3+ GHz, and have 8 or 16 cores, they'll easily generally outdo this old -but very usable still- Intel chip.

Reminder: The Cortex-A76 cores in the Pi5 are 9.9 SPECint2006/GHz, only the UR-CP1000 is above that, but that doesn't support RVV.
The SpacemiT X100 is slightly below that, but has 256-bit RVV and RVA23 support.
