Then just use the F - 5700F.
That would be problematic too don't you think? We are back to a confusing designation for what is a cut down CPU v. full cache and higher PCIe standards. The G tells you what series it is, just like KF with Intel. AMD already uses the F for non IGP models now, GF makes the most sense to avoid any confusion over CPU specs IMO.

With Intel, anything with an F at the end is sans graphics. With AMD, all the Ryzen CPUs before the 7000 series were sans graphics unless in has the G. So, yes, considering the prior labeling, perhaps a little confusing. But, it would make the prospective buyer delve a little deeper since it would be unfamiliar. Or maybe just 5700nonX,

But then people will think that only 5700F doesn't have graphics 🫠
This and other reasons mentioned are probably why AMD just went with 5700. Really, any naming convention change, at this point in time, for any AM4 socket processors is going to introduce confusion. Unless the prospective buyer know how to google something, of course.

And the 5500 does exist. It is a good counterpoint to Steve's saltiness. I'm ready to flip flop and go back to my original stance that it's fine. 😁 Needs a price cut though. The 5700G was just under $160, paying more and getting less is uncool.

I'm not on Twitter coz I only used my account to read tweets and follow and then Musky Wusky bought it and flagged me as a bot so can't tweet this but I really think #AM4EVA should be a thing.

Would someone start this on Twitter on my behalf?

Let's not let AM4 die ever and get AMD to release at least one new AM4 CPU every single year for the next 10 years!!!

I was recently looking at the 5700, as I was considering a basic, cheap AM4 build or AM5 build as a 2nd NAS/server. However, The 5700 is technically Cezanne, not Vermeer. What is the significance of this besides less cache and no PCIe 4? Well, since it is not a Ryzen Pro chip, it does not support ECC. Vermeer supports ECC RAM, board and BIOS allowing of course. With Cezanne, only the Ryzen Pro chips support it.

In the end though, I probably shouldn't be spending more money on motherboards/CPUs/RAM so much, so I will probably just reuse an old X58 board and Xeon combo for the 2nd NAS, even if it doesn't have ECC RAM.

5700G being 18% faster in apps than a 5600X and 1% faster than a 5700X so should the 5700.

That information will sell ones of retail 5700s. Either it's a time is money workflow in which case the 5700 makes no sense. Or the apps are casual use and the 5700 makes no sense. They will sell more off of the gaslighting name than its productivity performance. Retail is predominantly gamers as evidenced by how long the 7800X3D has been number one on Amazon and Newegg U.S., polls I've seen also reflect it in how many users have a 3D CPU. 5700 isn't going to sell for beans without a substantial price cut IMO.

Thank you for posting those benchmarks! They're quite thorough, and some of the results are surprising. Never imagined the "G" beats the "X", even by small margins...

You re welcome, but beware that as pointed by the members here it s only for apps, in games that s another story due to the bigger cache of the 5700X.

In addition to more cache, I thought the 5700X also had a higher boost clock compared to the 5700G. So how can it be slower in anything?

Same ST boost at 4.6Ghz, guess that you confused with the 5800X.

The slight 1% difference in MT (3% in CB R23) is that the 5700X use 7W more when idling due to the IOD than the 5700G, so the latter s cores will have each 1W more since both have a 88W PPT.

Never noticed this before but 7900X3D having more L3 than 7800X3D means that some testing could be done by turning off two slowest cores on each CCD and then pitting it against 7800X3D to see the performance impact in the most cache sensitive games/workloads. Another approach is to choose the two best cores on the frequency CCD and turn the other four off while keeping all cores on the V-cache CCD active.

Like if you think this is worth investigating. Better yet, link to a review that has already done it!

it will be worse, since L3 on dual-ccd chips is not shared by all cores. It's split.
