AMD Zen 3 (5000 Series), rumored 17% IPC gain.

Does anyone know if these are going to use more power or less? My understanding of shrinking to a 7nm die i would expect it to use less power. I'm just wondering whether these chunky VRMs are going to matter in the end really. Especially as AMD seem to be tuning their silicone to such an extent that, most of the time, you're getting the max out of them at stock.

Maybe their going to try push the clocks higher but even then i doubt you would need anymore than a B450 for 8 cores.

The 3700X is getting closer, already down to 290 at most places...

That's around 10-15%, such a small drop for a whole generation, how big a drop do you think likely once Zen 3 launches? I was thinking of upgrading from 1700, but drops are too small to justify, I was thinking it's a better deal to get Zen 3 at launch (though i'd also need a new MB).
 
The post you quoted me from there was back in January, so 10-15% drop on something that had launched only a few months earlier isn't to be sniffed at in my opinion! It's dropped down to around 275 now and of course it's still the current generation (not quite sure what you mean by "such a small drop for a whole generation"?).

The Zen 2 launch saw some serious deals knocking around with the outgoing 2XXX series chips and given how performant Zen 3 is looking from the rumours I think you'll again see heavy discounting of the outgoing 3XXX generation, but to expect it now is too early... Zen3 isn't due out until closer to the end of this year. Either way I would personally wait a few more months with your 1700 until Zen3 now to upgrade, it's lasted you this long already! You can either get a great deal on a 3700X once they are the outgoing chips or, if it seems worth it to you for the extra, spend more and go for the Zen3 equivalent and new motherboard. Either way you get more bang for the buck than buying now.

Sorry, I didn't check your post date. The 3700x is exactly at £290 on AZN today, a little more on OC.

This is my first build, so i wasn't following what happens to chip prices when the proceeding generations launched, so it's useful to know they'll be a drop. I'm very curious what they do with X670 to diffrenciate. You're right, it makes sense to wait.

Some details of the g processors released:

No increases in clock speed really, which is a shame. Time will tell on the performance in benchmarks

Fairly significant clock speed increases on the GPU side though - be interesting to see what difference it makes, although I imagine it's still going to be limited by memory bandwidth (2.1Ghz/8 Compute units vs 1.4Ghz/11 Compute units and 1.25Ghz/8 Compute units of the older models)

A few more details and comparisons vs older parts here

No increases in clock speed really, which is a shame. Looks like it's likely to be a performance improvement from the architecture change and that's about it. Time will tell on the performance in benchmarks but there are a couple of crappy benchies in the above link too

You probably know, but to be clear for anyone reading this that doesn’t, the 4000 series APUs are based on Zen2 so don’t really indicate what we can expect from the “proper” 4000 series CPUs.

AMD’s naming conventions are a travesty at this point!
