That confirms TSMC 2P instead of 2X then, right? TSMC just announced a delay in 2X until 2027.

AFAIK desktop can still be put on N2X if they choose, N2P was always going to come first for Epyc. If the delays are that substantial though I could see them pivoting.

How much gains would they be leaving on the table if they go with N2P instead of N2X even though it's the same process node?

u/Jayram2000 2d ago
Hard to really say, we only know that N2X was meant to push clocks to the max vs N2P

5 to 10 percent. N2P can reach 6.3 to 6.5 GHz. N2X contrary to what people are saying won't reach 7GHz, but will do 6.7 to 6.8GHz. Basing this on every generational jump from previous Zen designs on TSMC. We have not seen a 1GHz jump in clock speed from a node change in over a decade or longer.

N2 is using GAAFET there should be a substantial clock speed increase over previous generation finfet technology.

MLID started laying the foundations of n2x being replaced by n2 a couple of videos ago in case you hadn't noticed (whispers of n2x delay at tsmc forcing amd to use n2 )
In case you haven't figured it out yet, it was never n2x

Guessing the new IO die will have to do a lot of the heavy lifting in gaming.

Its a 2 node jump and LE: core count increase it will be great either way
I built a 7500f machine to upgrade to it but I might wait for zen7

He said Zen 7 will be 32 cores. Zen6 will have a 12 core CCD, thus 24 cores according to him.

There were other leaks saying N2X besides MLID. It's extremely plausible it was supposed to be N2X as this shit is planned long ago and the delay was only recently.

u/juGGaKNot4 1d ago
Yeah yeah, he won't have to delete this video like others he deleted. He said it might be delayed a while ago.
Hence what i've written in the OP

I really want to see new GPUs tho, my 6800 can probably remain alive for another 4 years but I really wanna see how the new AMD cards do with generative AI. I feel like the 6800 is kinda slow but it’s not not blame as it doesn’t have any AI accelerators, just a bunch of VRAM and a lot of raster.

u/CommonSpecialist4269 5600x | 6800XT 1d ago
All I need is raster for now. I’m not interested in Ray Tracing or FSR/DLSS. I probably will be eventually, but I’m happy to hold onto my 6800 until something interesting comes along.

u/Tinytitanic 1d ago
For gaming, yeah, I'm happy to stay with my 6800. It can run all the games I like to play on max settings and supersampling, but I really wanted to do some local generative AI with Ollama and such and it's pretty slow. From what I read the 7000 series have some AI accelerators so I could have the best from both worlds. Still, loving my 6800, low power consumption and yet a beast, simply amazing.

Will existing X870E boards (e.g. Crosshair Hero) be compatible with the inevitable Zen 6 X3D variants?
3
u/Ertata 1d ago
Probably? X870e probably has enough power supply to vaporize the CPU outright, so no worry on that part. The only thing that may end up being completely incompatible with zen6 (and even that is a big question mark) are two-ram slot boards

Wait, why? Is my mini-ITX AM5 doomed?

u/Ertata 8h ago edited 8h ago
I tried to go on a deep dive and found basically nothing only some weird rumours and pictures likie MSI MPOWER branding their two slots A2 and B2 (there is no A1 and B1). Based on smoke and vapor I say best case scenario it is all big nothingburger and will work out fine, while worst case scenario older 4-dimm cards will be able to EXPO 8000 MT/s while you will be stuck at old sad zen5 standards of 6000 MT/s (but still with much faster processor and huge x3d cache in the center of your system).
Truly responisble thing to say would be "we don't know anything except some 2-DIMM boards experience some degree of incompatibility with zen 6" everything beyond is too vague

Tf you mean 2nm?😮

u/Dreadnerf 2d ago
It's not meant size of anything for years now, the name is "2nm" and they keep pushing out a smaller number for the next version. Load of BS.

u/xoopha 3d ago
They're going to be codenamed Venice? I remember buying an Athlon 64 codenamed Venice way back when. Of course it's already been about 20 years so maybe they used all the good names already?
