AMD Ryzen Memory Analysis: 20 Apps & 17 Games, up to 4K

[SageWolf]

1) "again... amd failed because 5.5%". But when it's nvidia 5.5% faster in selected games or intel, it's also AMD failure. So it's always AMD failure, no matter what. I don't think so, as most "reviewers/benchmarkers" say 5.5% it's enough for a win and it's an improvement. BUT...... ----> go to point 2)

2) It's not really 5.5%, right? it's more like, some games improves nothing, some others, many, improves more than 10 FPS. I saw one like 12 FPS faster at 3200 mhz. That isn't a lot just because a faster ram stick? looks like a lot.

3) "3200mhz ram, the limits of the impossible!!" Well.... right now that would be 3600mhz ram

. But just be patient, with time 4000mhz will be common currency in everyday build for r5 and r7 ryzen cpu builds.

Let's see a Re-Review of ryzen with 10-20% improvement in a few months like Hardware Canucks did with polaris huh?

Note, this is not aimed at you SageWolf, just a general observation I've been meaning to vent about that your post reminded me of.

I also wish folks on the interwebs would stop going on about "xx fps faster". We all need to ONLY talk about % as e.g. 5fps difference at 150fps is barely noticeable but at 25fps is huge.

Often there is no context given just "blah blah, I got 5 more fps in xxx on my yyy".

 

[HD64G]

Look carefully at 2:54

and get stunned when you learn how much faster can Ryzen get with just a bios update

And then think of a few updates, faster RAM compatibility, proper cpu usage by better OS support.

It has a lot more to give imho.

All who looked Adored videos and similar stuff should watch this aswell:

tl:dw: Nvidia does fine in DX12 with Ryzen 7.

 

[Super XP]

There's "A LOT" more hidden performance coming soon to Ryzen.
Game Optimizations, Bios Updates, actual GPU driver updates to better work with Ryzen chips, OS Optimizations, faster Ram to also benefit "IF". And so on. Endless possibilities.

So many angry people online calling Ryzen the FailDozer., just because equivalent Intel Chips get what? 10-15 more FPS out of 150+ FPS? Lol ridiculous.

At least there's One hard Fact I'll continue to hammer away, Ryzen guarantees you Smooth Gaming, regardless of Frame Rates. And this is based on 80% of official review sites. Anantech, Guru3D, etc., included.

So let the Ryzen AM4 platform gets its continued updates and EnJoY the fact that AMD has now given us a CHOICE. Finally.

I'm chomping at the bit to get some R7 paired with Vega data.

I hope that Vega Fury X2 is real and available at launch ..... dribble, pass the tissues!

AMD is scrapping the Fury name seeing how Fury didn't live up to the hype. And despite its massive 4096-Bit memory interface.

RX-Vega should pound the Fury X by at least 2.5X it's performance. If not more.

It's true Ryzen is doing great on 1% percentile and 0.1% percentile FPS, way better than i7 7700K for example. This has to do with the 8 cores that Ryzen has compared to the 4 cores of 7700K as well as the better latency on its L1 + L2 cache.

This is strictly on topic and proofs what I said as well.

 

[EarthDog]

I really don't think core count has much to do with apparent smoothness in game... add cores to intel, or tale them away from ryzen... it's still as smooth...

I'm only repeating what reviewers say, they think in some heavy games it's due to more reserves on the 8 core CPUs (Ryzen), but I added my own theory, it possibly being the better/faster L1/L2 cache of Ryzen compared to the entire Intel Core architecture (all gens). That said, I think 6/8 core Intel's are smoother as well unless it's the 2nd reason.

Actually I was only referring to the 7700K. for some reason, there's enough reports and reviewers that claim it causes micro stutters. But the 6700K for example does not. So is there something wrong with the 7700K? Perhaps.
Thanks for the video, ya I've seen that, can't wait to see the Ram pushed even faster. What effect it will have on IF.

I think Ryzen scales nice up to 2933/3200, after that the curve flattens a bit, but scaling continues, may continue endlessly, lifting that bottleneck infinity fabric a small bit every time after increasing the Ram bandwidth. I'd like to see it with the best possible DDR4 there is atm (4200?), but I guess the curve gets really flat after 3600, also depending on the game tested. It's also important to note, that games where Ryzen runs very well on don't need very high clocked Ram for it to run really good, they easily get along with 2666 or 2933 DDR4.

On the i7 7700K: wow, that would be bad - well I don't like the 7700K anyway, fucking rebrand for high money.

 

[Relayer]

There are 5 games that greatly benefit by 13-17% when going from 2133 to 3200MHz RAM (Hitman, FC Primal, Civ6, Fallout4, Warhammer) and most of the others gain very little with Dishonored2 gaining 9%. It depends on the game engine I suppose. So, gaming performance of Ryzen clearly depends on RAM speed, along with game engine optimisations.

Yeah. I have to disagree with the technique of averaging them all out and then concluding RAM speed doesn't matter for gaming.

 

[uuuaaaaaa]

Interesting!

 

[medi01]

How about doing 1% and 0.1% percentile for gaming. Average fps does not tell the whole story, especially with higher ram frequencies.

Indeed, avg fps doesn't really tell the real picture.

From other reviews, most boost from faster mem was to min fps/ 1% / 0.1%

 

[medi01]

Yet, it's still dumb, b/c it's slow.

I wouldn't call it "dumb". Cache access figures I've seen weren't that bad either, within CCX (4cpu block) it was faster than intel's cache, across CCXes (using IF) about 2 times slower. Still pretty cool.

There is only mild perf hit in (emulated) 2 + 2 vs 4 + 0 scenario (games):

I also doubt it can be "addressed", as the whole concept is to have 4 core blocks and other CPUs created from those blocks, connected via infinity fabric.

@Super XP: re "Vega Fury" I was obliquely referring to the WCCFTech article on Vega, a bit tongue in cheek TBH as we all know how reliable there stuff is, the do somethimes get it right too though.

I did read that ZEN+ or ZEN 2 (Same thing) coming in early 2018 will resolve any latency issues and/or any speed related issues. Let me see if I can find that info so I can post. I think one being allowing much higher Ram to be supported.

Infinity Fabric Is in its infancy. I just find it quite innovative. What if that ran at the CPU speed instead of the IMC?

 

[nemesis.ie]

What if it also had its own port connected to the GPU? Inside an APU that would make a lot of sense and also possibly on multi-ship cards.

I think Vega also has the infinity fabric thing too...

Yes VEGA does have it and it pushes 512 GB /s too. Curious to see how a VEGA will perform with Ryzen and with an Intel CPU. Will it run faster with a Ryzen? We will see.

Welp, what issues?
Perf difference (in games) between 4 + 0 and 2 + 2 is lower than 5%. How far lower should it be not to be considered an issue? In my humble opinion that's dayum good.

Zen 2 will show more consistent performance, according to anand. When tuning all that "branch prediction" logic, Intel has enough resources to do it using much wider range of apps than AMD. That's what Zen 2 (using AM4 socket, f*ck you intel) will do.

I think Vega also has the infinity fabric thing too...

Makes me wonder about implication about dual chip "Vega Pro", connected using IF.

Maybe it won't use a PLX bridge chip this time?

 

[nemesis.ie]

That's my thought too, if the have a DF connection they wouldn't need a PCIe swtich from PLX (or another company that makes them) and the DF should be faster by around 2x at least.

That said, they probably could have used the original HyperTransport in the older designs but didn't, but now they have more of a need to integrate stuff in CPU/GPU and data centre racks so it probably makes more sense now

Thanks for this article, W1zzard. I actually had that motherboard, the Gigabyte Auros Gaming 5, and returned it to the store because my G.Skill Trident Z DDR4-3200 CL14 32GB kit memory wouldn't break 2933MHz, no matter what I did. It was using Samsung chips, but it would NOT clock the ram any higher than 2933, which annoyed the crap out of me. I'm frantically looking for any post/article/review that shows this ram hitting 3200MHz or higher on any motherboard. I'm thinking I'll grab one of the 4 (currently) motherboards that have an external BCLK generator: Asus Crosshair VI, Gigabyte Auros Gaming 7, Asrock, Taichi or Asrock Fata1ity Professional, but of all of these, the Gigabyte Gaming 7 is the only one with a dual bios (like the Gaming 5 has), but the Asus Crosshair will take my Corsair water cooler because it accepts socket AM3+ coolers.

Decisions, decisions!

This dude managed to do 3200 with dual rank 2 * 16 GB GSkill RAM @ CAS 16.

Pic is a bit hard to see, though.
