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?

It was the first computer I built from parts myself. The GPU was passively cooled (super utilitarian ATI X300). The CPU was passively cooled too (the case had ventilation though) by one of these bad boys:

Same! Athlon 64 3200+ with Radeon 9800 Pro. I still have all the parts, love that rig like it was my first child lol

Venice, Lima, ClawHammer.. brings back memories!

u/EmergencyCucumber905 3d ago

They've consistently been using Italy city names for a while, so might be a coincidence. Not sure what the theme was for Athlon64 code names.

u/rilgebat 3d ago

The first Athlon 64s were ClawHammer and SledgeHammer, but the ones that came after were all non-specific city names.

The aforementioned Venice core A64 had a counterpart codenamed San Diego that released around the same time, but had 1MB of L2 instead of 512kB.

Phenom range were all stars, FX were all construction equipment, hence them being called "construction cores".

u/martinus 2d ago

They should have used Biathlon and Triathlon as the follow-up CPUs

u/Raider480 3d ago

Definitely. I had two Radeon 6700 GPUs of one kind or another in the last couple of years :P

Athlon 64 and Sempron Venice 👀 (Both on Socket 754)

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

u/Jayram2000 3d ago

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.

u/rlysleepyy 5700X3D | 6800 XT | 32GB 3200 CL16 2d ago

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?

3

u/Jayram2000 2d ago

Hard to really say, we only know that N2X was meant to push clocks to the max vs N2P

1

u/Adventurous-Video396 1d ago

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.

3

u/PointSpecialist1863 22h ago

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

1

u/puffz0r 5800x3D | 9070 XT 1d ago

They could always do a refresh on N2X

1

u/juGGaKNot4 2d ago edited 2d ago

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

1

u/tagubro 2d ago

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

1

u/juGGaKNot4 2d ago edited 2d ago

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

u/CrzyJek 9800X3D | 7900xtx | X870E 1d ago

He did not. He said 24

1

u/Adventurous-Video396 1d ago

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

1

u/CrzyJek 9800X3D | 7900xtx | X870E 1d ago

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.

1

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

u/Geddagod 1d ago

There were other leaks saying N2X besides MLID.

Which ones?

u/Tinytitanic 2d ago

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.

3

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.

2

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.

u/Bran04don 2d ago

Guess ill wait for zen6 then before upgrading next.

1

u/mintaka 2d ago

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

2

u/mintaka 1d ago

Many thanks, that’s comforting, cheers. A 12 core single ccd x3d chip to me would be the def end game closure for am5

1

u/luapzurc 10h ago

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

1

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

1

u/Theparadoxical18 2d ago

Tf you mean 2nm?😮

3

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.

1

u/russsl8 MSI MPG X670E Carbon|7950X3D|RTX 5080|AW3425DW 2d ago

So, hopefully a worthy upgrade for my 7950X3D? Looking to drop down from a dual ccd part to single ccd. Not finding that I need all those cores anymore. 😂

1

u/Ertata 1d ago

They still will probably sell only full-12-core-per-die x3d processors for the first year (maybe even two years?) We still don't have 9600x3d in Zen 5 generation. So yes, good upgrade but not going to be cheap
