I haven't used one. But would expect at least an extra 100mhz from PBO.Hmm, very tempting.. do these clock close to the 5800X with PBO?
Thanks, I'm still on a X470 Mobo and 2700X with PCI-E 3.0 anyways, but think I'll still hold out for a $300ish 5800X deal with the extra cache now that I know that.I haven't used one. But would expect at least an extra 100mhz from PBO.
I think there are two more important things about these to take note of, in comparison to the 5800x:
They do not support PCI-E 4.0
They have half the cache, which results in a fair bit less gaming performance at 1080p and even 1440p. Making it sit between Zen 2 and the full Zen 3 chips.
Here's a nice comparison of the 5700G vs. 5800x at equal clock speeds.
Even though the 5700G only has 16MB of cache vs. 32MB of the 5800x it doesn't seem to be too big of a detriment. FWIW...the 11700K also only has 16MB of cache.
When really comparing----the cache makes a pretty big difference. In the first two games of that video, 20 - 30fps difference. That's huge. And overall, its a generational difference. halving the cache makes it perform similar to Zen 2. And if it werent' for the overclock, it would be even closer to Zen 2. that said, its not a bad CPU, just like how Zen 2 is still great. But....people should not assume this is just a 200mhz slower 5800x. Halving the cache is a pretty big deal.
Techpowerup found that CSGO, it can mean 100's of FPS difference. And they also showed similarly large differences in CPU limited games, as that video shows:

Techpowerup also found over 1500 points less in Cinibench R23 multicore test. Again, that's nearly a generational difference.
P.S. The cache size of the 11700k is irrelevant here, as the architecture is completely different. And as you can see, 11700k is doing relatively better than the 5700G. If 11700k had more cache, it would do even better. Hardware unboxed recently used a 10900k to show the importance of CPU cache, for gaming performance:
