Discussion AMD Cezanne/Zen 3 APU Speculation and Discussion

Fresh leak out today, not much is known but at least 8cu's is confirmed. Probably an engineering sample, core count is unknown and clocks may not be final.

This is very interesting to me because cezanne is seemingly 8cu only, and it seems unlikely to me that AMD could squeeze any more performance out of vega. A cpu only upgrade of renoir may be lackluster compared to tigerlake's quite large GPU.

What do you guys think? Will zen 3 be a large enough improvement in APU form? Will it have full cache? Are there more than 8cus? Has AMD truly evolved vega yet again or is it more like rdna?

So, after Cezanne, what would be the most advanced AM4 CPU?

 

[Asterox]

GTA5 4K, it is ok very satisfactory.

- iGPU Vega 8CU, 2400mhz

- 4400mhz DDR4 memory

 

[Shivansps]

and that is single rank, so there is room to improve yet.

How did you get that information, after all that would be completely absurd.

Yes, 2x8GB DDR4-4400 is 100% single rank. Only dual rank 8GB modules existing are old ones with 4Gbit ICs from early DDR4 era, those are phased out and not capable of 4400 speeds. 4x8GB would make memory dual rank but 4400 might not be achievable.

Yeah he needs to use 4x8 or 2x16. But getting DDR4-4400 DR to work is unlikely. So in the end the difference may not be much.

Very useful comparison.Ryzen 7 PRO 5850U, difference in performance Windows 11 vs several different Linux versions.

Blender 3.0 CPU only, on Linux 20% faster vs Windows 11.

Finally unboxed my Ryzen 3 5400U (Lenovo L14 Gen 2).

Haven't tried any games yet but here are some synthetics. Almost 7700K territory at ~20 watts. This is with substandard 2666mhz CL19 (2x 8GB). When things settle down I'm going to get a 3200mhz CL18 kit which should add a bit more performance (mostly in games).

Browsing various i5 12400 tests, Twekers offers several interesting results.We can see a couple of interesting results in favor of the R5 5600G.

- 3D Rendering, in Fusion 360 red is faster vs i5 12400 and R5X

Fusion 360 is not very commonly used testing software.

De Intel Core i5 12400 is op papier een erg interessante processor die het AMD lastig moet maken. We bekijken of Intels antwoord op de Ryzen 5 5600X overtuigt.

DaVinci Resolve is also not very commonly used testing software.Adobe tools are always used for testing, but hey Davinci Resolve it actually offers a very capable free version.

Here's a review of a 5800H laptop with a 110 W PL1. Switching to "Balanced" mode (54 W PL1) doesn't reduce performance that much though.

Here's a review of a 5800H laptop with a 110 W PL1. Switching to "Balanced" mode (54 W PL1) doesn't reduce performance that much though.

Because the CPU doesnt get above 72W.
65W on average for Prime 95, thoses PL1/PL2 are well above the actual power.

 

[LightningZ71]

My son has an Asus scar 5900hx + 6800m laptop and there's not much of a practical game performance difference between balanced, performance and turbo in the Asus tools. He just keeps Windows in balanced mode almost all the time as it stays very quiet with very high frame rates at 1080p.

 

[Asterox]

As expected, 6/12 Alder Lake i5 vs 6/12 R5 5600G(cheap but good AM4 motherboards) offers satisfactory iGPU gaming performance.

R5 5600G, without severe headaches you can wait for discrete GPU prices to fall.

It's a surprise (for me) that R5-5500 is a Cezanne variant:

https://twitter.com/i/web/status/1500155436036550663

which is iGPU disabled one, how many core/thread count is still questioned but I guess it's 6C6T, according to videocardz it's priced 122 USD, a new choice in entry level

AMD rumored to launch Ryzen 5 5500/5600 and Ryzen 7 5700X this month - VideoCardz.com

AMD might launch not one but four consumer Ryzen CPUs this month AMD has been preparing as many as four new parts based on Zen3 architecture, mainly focusing around the mid-range segment. According to MEGAsizeGPU, AMD is expected to launch another two 6-core Ryzen 5000 SKUs: Ryzen 5 5500 and...

edit: someone easily reached 4400 RAM with it so it's 100% Cezanne without iGPU

[Shivansps]

There is also a R7 5800 around.
So... AMD wants to push non 3d Vermeers out of production and move everything to Cezanne? Keep 5500/5600 Cezannes and the R7 5700X/5800 is the same Veermer die whiout 3D? 5700X may be Cezanne too.

I think it's just them unloading the busted IGP dies.

Hm maybe, or by logic R5 5500 could be only 6/6 model.

That should be an excellent budget contender if it has the full L2 available. As you mention Cezanne also has a very good memory controller, so expect decent memory overclocks.

Only using good 8 MB L3 dies would help differentiate it a bit more from the 5600, esp if it's going to be $50 different. But it could be 16 too.

 

[LightningZ71]

Too bad its a poor fit for their budget video card, the 6500xt. Being restricted to PCIe 3 is going to make that a poor fit.

 

[Shivansps]

I know, but since they are moving to AM5 this year i expect Vermeer to be discontinued soon and Cezanne to stay for another year or two.

 

[Asterox]

Hm another source, a little different information or R5 5500 is 6/12+considerably less L3 Cache.

If this is legit, this is very obvious.

- R5 5600, Vermeer

- R5 5500, Cezanne no iGPU

 

[Thibsie]

If 5500 is gpu-less Cézanne, it seems about right to me.

 

[Insert_Nickname]

That 4600G looks interesting as an upgrade for older 300-series boards that can't handle Cezanne/Vermeer.

 

[burninatortech4]

It's encouraging to see them keep 4*00 series naming for Zen 2 parts. I think it was a major mistake to label 5500U, 5700U as 5*00 series.

Not sure why they did it here and not there but... AMD
