- brucehoult 1y agoSo 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.
- snvzz 1y agoMain 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.

- nubinetwork 1y agoI'm okay with ddr4 as long as you can still buy it.
- camel-cdr 1y agoReminder: 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.
- 6SixTy 1y agoNo V instruction set is going to be a big handicap though, as that's pretty much RISC-V's equivalent of AVX and missing those instructions is going to suck big time.
- snvzz 1y agoRVA23 compliant implies V. Two of the three processors seem to be RVA23.
- 6SixTy 1y agoPretty much my issue is that the one that is the closest to shipping is also the one missing V instructions. I am far more skeptical over potential processors especially after Horse Creek just vanished into thin air.
- karunamurti 1y agoTwo just say RVA23, one is "Compliant with RVA23 excluding V extension".
- snvzz 1y agoIt's a long way to say "Not complaint with RVA23."
