Question Zen 6 Speculation Thread

[branch_suggestion]

Has he made those other predictions before, so that magically AMD 'changed the design'? Wouldn't be the first time from someone with that kind of history.

That is my assumption.
Would be tricky to fit such a long CCD in AM5.

 

[Kepler_L2]

It's rumored to get RDNA5 graphics.

Nah, it's RDNA 3.5 with some enhancements.

 

[adroc_thurston]

Nah, it's RDNA 3.5 with some enhancements.

That's for Gator Range/MedusaDT.

 

[Kepler_L2]

That's for Gator Range/MedusaDT.

Pretty sure it's for Medusa Point too.

 

[gdansk]

Pretty sure it's for Medusa Point too.

So it's still N4P?

 

[Kepler_L2]

So it's still N4P?

The IOD? Probably not, the GPU IP exists on N3E too.

 

[gdansk]

the GPU IP exists on N3E too.

For what else?

 

[Kepler_L2]

For what else?

The original Strix Halo design

 

[Ghostsonplanets]

Nah, it's RDNA 3.5 with some enhancements.

Wait. So GoldenPig was correct about RDNA 3.5 being long-lived GFX IP?

 

[Kepler_L2]

Yep, not sure why gfx12 was skipped for (almost) all APUs.

 

[del42sa]

Pretty sure it's for Medusa Point too.

so only new X-box have RDNA5 or new X-box gonna stick with RDNA3.5 too ?

 

[mostwanted002]

@GTracing appreciate the TL;DR man. rayge:

Yay, RDNA 3.5 is the new Vega

 

[Kepler_L2]

I think it's gfx12 for the handheld and gfx13 for the console

 

[Ghostsonplanets]

I think it's gfx12 for the handheld and gfx13 for the console

So handheld is coming sooner than nextBox? As I assume the reason for GFX12 would be that they froze IP choices earlier.

 

[Ghostsonplanets]

I mean, it's not bad. Vega was available from dirty cheap to premium, so I assume RDNA 3.5 will be the same. AMD needs to have better availability of their designs at the bottom of stack.

Competitiveness though, 16CU feels it will barely handle against PTL 12 Xe³. Increasing shader count doesn't feel likely, so I guess AMD will take the gains of N2 and speed optimize the routing of RDNA 3.5 even further for increased clocks.

Yeah the handheld is supposed to release next year afaik.

 

[Ghostsonplanets]

Yeah the handheld is supposed to release next year afaik.

That's way earlier than what I thought. Will be interesting to see what performance level the machine will have.

So what are current thoughts on overall IPC (throughput/MHz) increase for ST for Zen 6?

Are there still some who are going to make outlandish claims like they "invented the question mark" and that Zen 6 will be +30% ST over Zen 5?

 

[gdansk]

So what are current thoughts on overall IPC (throughput/MHz) increase for ST for Zen 6?

My thought is 1.11x SPECint 2017 1T + 300MHz. So 1.16x overall.

Based on a single slide and my hopeless optimism that clock rate will increase even for desktop.

 

[fastandfurious6]

zen 60% !!!!!!

4nm -> 2nm gonna be big 💹💹🚀🚀

I think the 1.1 is a very solid prediction. 5.7GHz>6GHz seems like a stretch though.

 

[fastandfurious6]

6ghz for zen 6! great marketing material. it's doable

 

[blackangus]

6ghz for zen 6! great marketing material. it's doable

6Ghz Zen 6 with 600MB of L3 and DDR6 on 6/6 of 2026...

They cant pass that up.

 

[basix]

600MB are a little far fetched, but 12MB/Core at 12Cores (12 = 2*6 ) with V-Cache seem to be reasonable
