Ryzen Owners Zen Garden

[tabascosauz]

I guess I just don't understand how some games can run at 4k 120hz on ps5 but a higher end 5600x rx 6800 pc like i used to own can't do 4k 120hz in similar games...

I heard after the leaked dieshots of the PS5 SOC ppl said it had 8MB L3 and 4MB L2? That would make it essentially an underclocked 4750G(E) tacked onto a RDNA GPU, probably why it'll never catch up to mainstream desktop Zen 2 on IPC despite being "Zen 2" which Renoir technically still is. Any Zen 3 Vermeer or Cezanne would leave it in the dust, even if clocked at 3.5GHz.

Also consoles are basically just upscaling everything, it's not even close to actual 4k120Hz

ah ok, I actually didn't know about the upscaling stuff. Interesting. PC to the moon boys!!!

cause they run lower settings on the console variants, and they've always fudged the resolution... it's never been 4K 120hz, it's been 720p-1080p 120Hz, with the 2D elements rendered in 4K on top

does anyone know the equivalency of the ps5 zen cpu to its modern day cpu? speaking cpu only not the gpu built in...

I think we can assume that the 4700S desktop kit is essentially a defective PS5 motherboard. Following AMD's naming convention, that CPU would belong to the Ryzen 4000 APU series, which uses Zen 2 cores. The 4000's architecture is Renoir, which itself is a refresh of Matisse, the original Zen 2 Ryzen desktop line.

The PS5 CPU is an 8c/16t SKU that runs at "up to 3.5 GHz", which is most likely its highest clock in low threaded scenarios. Now the slowest octa core CPU of the desktop 4000 APU line is the 4700GE/4750GE, which boosts to 4.3 GHz. So, the PS5 part would be significantly slower than that.

@tabascosauz have you tested the 4750G eventually? I'd be curious to know its boost behavior in games.

Console games are heavily optimized for a specific architecture. Many use dynamic resolution to avoid bottlenecks. They also use a unique mix of graphics/quality settings to achieve optimal performance under most conditions. These factors cannot be easily replicated on a PC. This is why we cannot directly compare game performance across different platforms, even if they utilize the same underlying tech.

 

[GerKNG]

just try to match the graphics settings on a compareable PC and as long as the game is not totally unoptimized you have the same or even more performance (digital foundry and other benchmark channels tested this a lot)

Not quite, I have the 4650G, the 8-core was and still is obscenely expensive for what it offers. Works the same way though, being the APU branch of Zen 2 it works similarly to Matisse, ie. lots of scheduler load migration all over the place, low 4.1-4.2GHz all-core, etc. No issues with hitting rated boost in games, because all Renoir chips are late 7nm production same as ~2020 production Matisse, unlike the dumpster fire 2019 Matisse CPUs.

The 4600G and 4650G get +100MHz "free" boost over what they're rated, you'll might see 4.3GHz on ST boost. Seems like the 4750G gets about +50MHz free boost to about 4.45GHz. It'll be interesting to see if this behaviour continues with 5600G, but I doubt AMD will make such an oversight with a non-Pro retail CPU.

The 4700S doesn't look too interesting aside from some lukewarm interest over its GDDR6. No iGPU, [probably] poorly binned cores, no mem OC, basically a less interesting Renoir with a lot of dead silicon.

wow. ok... sticking with PC.

Thanks for getting back! Does it also hit 4.1-4.2 all core when the integrated GPU is being fully utilized? And does the GPU clock down when all cores are loaded, to stay within the power envelope?

I haven't monitored it too much since I use it on my TV. At stock CPU, 2275MHz iGPU @ 1.2V and 2100MHz IF @ 1.2V, whole package power is still just 55-65W max. So if PPT is where it should be, not even close. Even heavily OC'd iGPU draws something like 40W out of that in games, Valley and Fire Strike. ST CPU boost never downclocks in game and the GPU power limit flags never come up.

Reviewers like Toms seem to be fixated on pushing unrealistic (and unsafe) static CPU OC while running Furmark and CPU tests at the same time to test the "power budget" which is pretty hilarious.

I guess it's still better than being HWUB or GN and "reviewing" a Cezanne APU with 3200CL14. "Oh but normal people don't buy 4000 Viper Steels" - normal people also don't buy 3200CL14 which is more expensive than 4400 Viper Steels, and knowledgeable reviewers understand the importance of bandwidth

 

[freeagent]

Hella bandwidth at 2100IF lol :drool:

I just got my board for my 5900x build. So ill be fairly active in this thread trying to dial stuff in.

X570S Aorus Master...

I got some Teamgroup Xtreems 2x16 3600 14-15-15-35 memory to slap into it.

or just run it at stock with xmp enabled. probably won't notice any difference in real world gaming regardless.

i regret tinkering so much, instead of gaming. i mean true its enjoyable, but on same hand, main reason for this stuff is to game.

That's some sexy hardware. I've got a Unify-X and G.skill 2x16 3600/14-15-15 upgrade arrivfing this week for my 5900X, looks like we'll be working together chances are you have a better 5900X than I do

I really wanted to wait for the MSI X570S Unify-X MAX, but I had no idea how long of a wait that would be, so I bit the bullet and got this one. MSI also needs to catch the f up and put external temp sensor ports on their AMD boards. Its one of the main reasons I got this Aorus Master other than it being sexy as hell with the real fin heatsinks for the VRM.

go look at a third person console game and look at the elements that are clear and crisp

It's the UI, and the characters clothing, hair and ass in front of your face. Everything else is blurry and high movement so you dont focus on it. (DoF, motion blur, etc)

If you're not mem OCing past IF desync, I don't think the Master offers any less capability and has better features? Although I'm confused as to why they left out the dual BIOS this time, the X570 Master dual BIOS with dip switches works fine.

Here the B550 Master and Unify-X are the cheapest non-garbage boards with a POST code and both sit at $349cad, so considering the idiotic auto dual bios and lack of a chipset M.2 on the B550 Master it was an easy choice. MSI BIOS gonna take some getting used to though, not a fan of it.

Are you planning on putting a temp probe in the socket?

No, its to run a temp probe fitting in my hardline loop to run the fans off of water temp rather than component temp. Its a new way of doing things within the watercooling enthusiast community. It makes it so fans don't adjust suddenly to even the smallest CPU temp change, so makes for a quieter system ultimately.

Id like to maybe run 3800 at tightest timings I can get within reason.

Honestly, in Aida64 when looking at reads, writes, and copies.. there is only about 10k difference between 3200 and 3800.. not much really..

That's a fairly decent jump considering the numbers that you can get. 40k to 50k is a 20% boost.

Just ordered these cables for the build:

 

[freeagent]

Well since you put it like that it doesn't seem to be that bad

 

[thesmokingman]

I was messing around with my 5900x to reduce the power because it is a bit warmer now ambient wise with summer and all. I enabled ecomode for the hell of it. Then ran R20. It scored 8300 and change.Regular oc score is 8800 and change. I noticed my old 3900xt balls out score of 7900 and change. Lmao even limited to 65w the 5900x is still a healthy clip faster.

 

[freeagent]

I have a guy coming to pick up my 5900X today. I want 2000 FCLK.. but not gonna happen with that CPU, it doesn’t really like 1800 much these days.. I was considering buying another 5900X, or even a 5800X.. they are fairly cheap now compared to a few months ago. Or should I just get the 5950 and call it a day? I am totally ok with a 5600X lol.. people say that they wouldn't buy 6 cores these days.. but they are fast as fuck boi, if you aren’t trying to make money from it.

Edit:

I will probably just go with a 5800X.

Kind of a shitty 5900x it seems. When did you get it. Im hoping mine can at least do 1800fclk since thats basically stock for my 3600 memory.

@R-T-B says 5800x is best because the latency is better on a single ccx die. that's also why it runs hotter. interesting though.
