AMD Zen 5 Chiplet Built on 4 nm, "Granite Ridge" First Model Numbers Leaked
An alleged company slide by motherboard maker GIGABYTE leaked a few interesting tidbits about the upcoming AMD Ryzen 9000 "Granite Ridge" Socket AM5 desktop processor powered by the "Zen 5" microarchitecture. To begin with, we're getting our first confirmation that the "Zen 5" common CCD used on "Granite Ridge" desktop processors and future EPYC "Turin" server processors, is built on the 4 nm EUV foundry node by TSMC, an upgrade from the 5 nm EUV node that the "Zen 4" CCD is built on. This could be the same version of the TSMC N4 node that AMD had been using for its "Phoenix" and "Hawk Point" mobile processors.
AMD is likely carrying over the client I/O die (cIOD) from the "Raphael" processor. This is built on the TSMC 6 nm DUV node. It packs a basic iGPU based on RDNA 2 with 2 compute units; a dual-channel DDR5 memory controller, and a 28-lane PCIe Gen 5 root complex, besides some SoC connectivity. AMD is rumored to be increasing the native DDR5 speeds for "Granite Ridge," up from the DDR5-5200 JEDEC-standard native speed, and DDR5-6000 "sweetspot" speed of "Raphael," so the cIOD isn't entirely the same.
Each "Zen 5" CCD is confirmed to contain no more than 8 CPU cores, and the "Granite Ridge" processor has a maximum of 2 CCDs, which means the CPU core counts is unchanged generationally—you have 16-core, 12-core, 8-core, and 6-core SKUs, spanning the Ryzen 9, Ryzen 7, and Ryzen 5 brand extensions. The slide also confirms the first four SKUs AMD is planning to launch—the Ryzen 9 9950X is on the top, likely a 16-core/32-thread chip. This is followed by the Ryzen 9 9900X, a 12-core/24-thread chip. After this, is the Ryzen 7 9700X, an 8-core/16-thread chip, and lastly, there's the Ryzen 5 9600 (non-X), a 6-core/12-thread chip. TDP ranges between 65 W for the 9600, to 170 W for the top Ryzen 9 chips, just like on the Ryzen 7000 series.

Would not surprise me if the names stay the same. Though they could also just be place holders at the moment.
Here is to hoping AMD improved the boot time fiasco that plagued Zen 4.
Mind you there's no need to "hope" for anything, that issue was fixed a long time ago.
Today CPUs and GPUs need new features. From a good iGPU if possible, to AI performance advantages from new CPU models. If AI turns from a hype to an important feature, to a strong marketing advantage, in a year from now we could have a situation where AMD will be losing CPU market share for the same reason it is losing market share in GPUs. Lack of features.AI and ML OPTIMIZATIONS (from the slide). Damn.... Another RX 7000 coming. This wording reminds me the raytracing performance increase they where promising with RX 7000 series. Practically there was little to none.
If I was a journalist at Computex this year, my go to questions would be: "Without using the term 'A.I.' why should consumers be excited about your product?" Haha.
AMD's APU's have had an NPU for over a year, while the upcoming CPU doesn't. You haven't figured out why? :D
Also, they should target low power, cheap cpu market, like the intel N series.
Imagine a 2 core chip, with a decent enough gpu, that can compete with the likes of the Pi’s and even a replacement for the Ngreedia Shield TV.
This leak here is much more interesting.
Lower TDP for ryzen 7 and slightly higher clocks.
Fwiw I don't think AMD will lose market share this round because of that, AI will not take off that soon. They will lose market share the usual way, being unable to build enough CPUs.
Though @TM, I believe their SBC-facing Ryzen Embed APUs are a gen or 2 behind.
(Happens a lot, when your target market demands 5-10+year product support)
Unless the game developers will seriously start to utilize multi-threading, there is no point in increasing the core count on CPUs. Thus the IPC uplift is much more preferable, or even one of the only possible ways to aid the steady core amount, outside better memory controller.
Zen 1 was grounds-up. This is another Zen CPUAI is already a marketing advantage, just not on the consumer side. And it won't likely go there either. I still have enough faith in humanity. We're trying it out now, and the early results are not encouraging. Meanwhile, the real cost of these solutions is slowly becoming impossible to hide for us, and they. Are. Immense.
The cost/benefit scenario just doesn't work here. We couldn't do an autonomous car yet without running into the human factor, not even pilot projects work out well. AI? Never. We're trolling it and having fun with it. It ain't gonna work.
This is also why Intel can't get out of its hole. They are tweaking their cores, but they're still stuck with their power budget, because they're still monolithic, really just iterating on the first dual core.
