Cumulative Ryzen 5000 series TPU review discussion thread

[Sybaris_Caesar]

I don't know if I should do this but seeing discussion regarding the reviews spread out in 3 different threads, I don't want my message to be lost. If it breaks any rules I'm sorry.

TPU's reviews are causing a lot of confusion among the masses. So far I've only checked r/hardware subreddit since I think it's the least biased in terms of userbase. Here is the megathread. A lot of people are either calling out TPU's numbers or calling out AMD based on TPU's numbers. Anthony from Linus Tech Tips had this to say about the situation:

Calling on @Wizzard to join the discussion.

I think I wrote down the wrong AGESA version number. I used the AMD provided BIOS

Edit: yeah it's 1.1.0.0. I had the BIOS version # correct (3.56), but typed the wrong version from memory. Fixed in all reviews now

Actually here's a crazy suggestion: merge all the discussions for all Ryzen 5000 CPUs reviews.

mine just shipped. my bios got a new update today too and its ready to go. but i still have to wait until nov 18th for 6800 xt... so my system will still continue to collect dust until then. but it will be nice to get it all built and ready to go other than slotting in the gpu.

best review of the day imo. its a great day to be a gamer lol tho i won't like... which they had a 5700x for $329... losing out on two extra cores kinda bummed me out but meh i really dont multitask at all, just game so it doesn't effect me

Sorry for going a bit offtopic, but has anyone seen a Ryzen 5000 review with 4000 MHz RAM, aka the sweet spot according to AMD?

it would be nice to see a review with this ram. 4000 cas 15... only 170 bucks...

 

[SL2]

Yeah, I mean I'm not going to check every review I can find, just hoping that someone happened to stumble upon one..

Only checked TPU and GN so far lol.

Since when is that the sweet spot?
The slide that leaked said that 4000MHz would be the same to the 5000-series as 3800MHz was to the 3000-series.
The "sweet spot" was meant to be 3733MHz, but clearly a lot of CPUs could do better than that.

I don't know how to answer that as you clearly know what I'm referring to.

I thought the limit was 4000 MHz, not 3733. (without divider)

 

[jesdals]

Well I would like to have seen Infinity fabrics settings on the reviews instead of standard - it should have been in the OC part at least

Mine says it won't ship until November 17th

The "old" sweet spot that is. I don't think AMD provided one for the 5000-series beyond what was in that leaked slide.
Sweet spot doesn't equal the highest possible speed though, as the logic behind the sweet spot was price/performance.
AMD actually never officially mentioned 3800MHz until the leaked slide for the 5000-series appeared afaik.
This is also why most reviewers stopped at 3733MHz and never even attempted 3800MHz.
Some CPUs could never reach above 3733MHz 1:1 either, so I guess this is again why it was the sweet spot.
As such, 4000MHz is to the 5000-series as 3800MHz was to the 3000-series, a possibility, but not guaranteed.
My guess is that the new sweet spot would be 3800MHz, but that you have a good chance to hit 4000MHz.

I'm not sure that it's needed. At the very least it looked like a legit slide.

OK now we're down to semantics. I never said that. The sweet spot I'm talking about here is getting as high clock speed as possible while maintaining 1:1:1 divider.

AMD actually never officially mentioned 3800MHz until the leaked slide for the 5000-series appeared afaik.

I highly doubt that reviewers were stopped by the lack of guidance from AMD.

This is true tho.

I'm pretty sure that's why AMD wrote "good luck!"

I guess some of it comes down to reading comprehension. Not everyone understands the minor subtleties of English.
And sometimes companies use "flexible" language to get out of trouble if they can't deliver 100%.

Please excuse my english.

I never said you said anything of the sort. I was simply pointing out that it was AMD's meaning of sweet spot, not specifically how people understood it. You're clearly proving that point right here.

Oh, of course not, but if you look at early reviews, they often stopped at 3733. Case in point "The DDR4-3600 Limit: Should I Try DDR4-3733 Anyway?"

Is Ryzen 3000 optimized for DDR4-3200? What if we want more? We examine everything from frequency to rank count to nail down optimal settings.

As for what will be the right thing to buy in this case, I don't know, but I would guess, based on that slide, that 3800MHz should be quite doable across all CPUs, with 4000MHz being better than 50% chance.

I still don't even know what AMD "sweet spot" you're referring to, you just made an assumption there I guess.
I wasn't referring to AMD's usage of "sweet spot", I used it based on my memory of that slide.

"Sweet spot" doesn't have to relate to price, even if it's a fairly common usage.

 

[sneekypeet]

There was chatter of 2000IF with 4000MHz ram. Tweaktown managed it in the OC section. As to how many CPUs can do it regularly, too early to tell.

Thank you, just what I was looking for.

 

[W1zzard]

AMD explained that 2000 IF is achievable by some good silicon CPUs, just like 1900 IF was possible on many Zen 2 CPUs, but not all of them

 

[MaurizioC]

I have found a review comparing ddr 3200 vs ddr 4000 for the 5900x.

fclk:uclk:mlck should be 1:1:1 for this test.

timings 16-15-15-15-36 for both 3200 and 4000

Exactly. It remains to be seen if the review samples are cherry picked, or how much BIOS can be improved.

I vaguely remember seeing somewhere that next AGESA will improve 2000 MHz IF achievability

It was a legit slide.

What people seem to be misunderstanding is that the referenced DDR4-3800 frequency AMD mentions in the slide isn't the sweet spot, it's what you could hope for. People that got lucky with the silicon lottery, had good memory kits, and solid motherboards were able to push their fclk to 1900 and maintain that 1:1:1 ratio while running memory at DDR4-3800. But you see DDR4-3600 recommended time and time again because it's the greatest common factor - the fastest frequency that you're basically guaranteed to be able to run and still maintain that 1:1:1 ratio. In this slide, AMD is stating that DDR4-4000 is what you can hope for as the best case scenario while still maintaining that 1:1:1 ratio. So it makes sense to extrapolate that if the best case scenario has improved, then the sweet spot has improved as well - probably to DDR4-3733 or DDR4-3800

I guess you never saw the slide below before then? It's what's normally referred to when talking about Ryzen 3000 memory speeds and why a lot of people are getting hung up on the whole 3733MHz thing.

However, as above, that slide leaked early and that's what I presumed you meant as the sweet spot for the 5000-series even though it doesn't mention sweet spot anywhere.

On top of everything else, this was presumed by a lot of people to be limited to two modules and everyone expected lower performance with four modules or dual rank DIMMs, when it fact either of those seem to boost the performance slightly on Ryzen whereas it does the opposite on Intel afaik.
