AMD Zen 5 "Nirvana" and Zen 6 "Morpheus" Core Codenames Leaked, Confirm Foundry Nodes

[btarunr]

An AMD engineer inadvertently leaked the core codenames of the company's upcoming "Zen 5" and "Zen 6" microarchitectures. It's important to understand here what has been leaked. "Zen 5" and "Zen 6" are microarchitecture names, just like the current "Zen 4" and past "Zen 3" or older. AMD uses codenames for the CCD (CPU complex dies) based on these microarchitectures, which it shares between Ryzen client and EPYC enterprise processors. For example, the CCD codename for "Zen 3" is "Brekenridge," and for "Zen 4" it is "Durango." AMD also uses codenames for the CPU cores themselves. "Zen 3" CPU cores are codenamed "Cerebrus," and "Zen 4" CPU cores "Persphone." And now, the leak:

The CCD based on the upcoming "Zen 5" microarchitecture is codenamed "Eldora," and the "Zen 5" CPU core itself is codenamed "Nirvana." There's no codename for the CCD based on "Zen 6," but its CPU cores are codenamed "Morpheus." The "Zen 5" microarchitecture will be based on the 3 nm EUV foundry node; while "Zen 6" will be 2 nm EUV. The engineer in the screenshot is contributing to the power-management technology behind "Zen 5" and "Zen 6," and states that their work on "Zen 5" spanned January-December of 2022, which means the development phase of the next "Zen" architecture is probably complete, and the architecture is undergoing testing and refinement. It's also claimed that work on at least the power-management aspect of "Zen 6" has started from January 2023.

Development of a typical CPU takes three years (one year for design on paper, one year for verification on silicon, and one year for verification in a package); if they started in January 2023, Zen6 would arrive in late 2025 or early 2026.

The N2 is expected to be ready for volume production in late 2025; AMD is almost certainly going to be the first customer, but competition from Apple is likely. According to previous rumors, the initial N2 will introduce GAA but not BPD, which will affect subsequent developments.

Nirvana is my favourite rock band of all times. I'll have to get one!

If it makes sense for amd to release the chips.

if there is low demand and no competition they will postpone.

They won't postpone, Intel's already emerging as a secondary threat in the server space & ARM is even bigger/worse threat than anything Intel can manage right now! AMD needs to go full throttle all the time otherwise they'll have very little in terms of profits to show for.

Naming is irrelevant, but it's good to know AMD has their ducks in a row for a few years already.

That's the development part. Preparing for HVM takes a long time too (could be months just for the ~100 photomasks) and wafer manufacturing takes ~3 months.

It's a constant cycle. When they release new CPU's they are already working on the next generation.

I know that, but with Zen5 on the horizon, I wasn't aware how Zen6 was faring.

I am looking for the AMD ZEN 4 7040 Phoenix = LPDDR5 + RDNA 3 + Pci 4.0 + USB 4.0 + HDMI 2.1 + Artificial intelligence with XDNA architecture developed by Xilinx and all at 4nm vs 10nm from Intel. With this processor in a laptop that weighs less than 2.20 pounds and can play triple AAA games, it's more than enough to pass the Zen 5, Zen 6 and all the rest. With this AMD Zen 4 7040/7045 you have plenty for more than 10 years

Nirvana is also one of my favorite bands. Smells like ZEN spirit!

"Inadvertently leaked". Yes! I believe it.

Its like a silent fart you never know who is close enough to smell it and say something inadvertently.

For gaming PC, CPU have become stupid strong enough, few years ago I'd be hyped but right now, for gaming, you really need a 4-5 years upgrade plan...I'd rather save money, put a mortgage and get a RTX 6090 than a Zen 6 for sure

For GPU, if they weren't so damn expensive I'd be changing them more often but at least they are the one making a real gaming difference

I agree about CPUs, but I don't think even GPUs make that much of a difference, at least if you're still on 1080p like I am. Even midrange cards are overkill for me at this point, both in price and performance.

I am not agree.
The CPU give you huge amount of multi-thread that's doesn't needed for gaming. But if you have one RTX 4090 you will bottleneck it even with top max clocked CPU.
So for the gaming you still need "faster" CPU. But faster not with just more cores, but with more IPC.

You're not wrong. That's why AMD's 3D V-cache works or why Intel's P-cores can hold their own against AMD CPUs with more cores.

Yes but at one point having more than 400 fps on a 240Hz screen is useless, be it it's bottlenecking a 4090 or no, only a very specific use case (esport, 500hz tn panels etc) would really benefit from 0 CPU bottlenecking, I don't think it justifies an intempestive CPU upgrade and huge CPU budgets in a gaming build for most use cases

You miss the point we talking about.
