AMD Zen 5 Chiplet Built on 4 nm, "Granite Ridge" First Model Numbers Leaked

[btarunr]

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.

I am not too surprised the processor counts aren't moving up since right now its hard to justify on the consumer level beyond 16 cores. I am very curious on the memory controller upgrade to handle higher memory speeds as that is pretty cool since AMD plays very well with faster memory which may in turn make overclocking memory go further.

Would not surprise me if the names stay the same. Though they could also just be place holders at the moment.

For those that do mixed productivity/gaming that want the best gaming performance will probably be most interested to know how many cores per CCD. If it's 8 like last gen I'll be most interested in a 9700X provided it uses 1 CCD. Anyway I'll be patiently waiting for a 9800X3D.

Here is to hoping AMD improved the boot time fiasco that plagued Zen 4.

Rumors say these slides are fakes too

Here is to hoping AMD improved the boot time fiasco that plagued Zen 4.

Boot time had nothing to do with the CPU, it was due to AM5 being a newer platform.

Mind you there's no need to "hope" for anything, that issue was fixed a long time ago.

From all we’ve heard so far, they are sticking with 8 per CCD for Zen 5 and maaaaaybe Zen 6 goes for 16. There are rumblings of a 12 core CCD, if I remember correctly, but that’s for Zen5c.

When will they learn to NOT do boring launches? No X3D chips? Any AI in these chips to at least have something new to hype? If they come out with 4 standard chips with 10-15% IPC improvements, while the IPC improvement will be really nice, that will still be boooooooooooooring. Because obviously prices of Zen 4 chips, that have come down considerably this last year, will be highly competitive compared with the MSRPs of the new chips. So in the end we will have nothing to cheer about. People will just keep holding out to see when X3D chips will come out and what the AI hype is going to offer. Intel could steal again market share from AMD, if next gen Intel chips play the AI game and consumers believe the AI hype.

Rumors have it that yes, there will be AI targeting enchantments, possibly powered by AMDs acquisition of Xilinx.

I am sorry, but these are CPUs. An iteration on the existing architecture, too. What, exactly, do you expect them to be so they aren’t “boring”? Should they do meth and throw wild parties Inside your PC?

I would like to second evernessince's comment. Boot problems were solved long ago through BIOS updates. These new CPUs shouldn't 'reintroduce' the long boots just because they are new.

Things change. Plain CPUs where OK a few years ago. There is nothing exciting in plain CPUs anymore. Intel's QuickSync, while already pretty old, showed that extra features some times count.
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.

Agreed.....it's almost like they WANT to hear all the AI marketing B.S.

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.

Of course I want to hear the AI marketing BS. This BS is about to sell Qualcomm ultra expensive laptops. Intel is going to use it to sell Ultra processors and AMD will lose ONE FULL F$%%&(# YEAR looking like fools and second class.

In the same way that Raptor Cove succeeding Golden Cove was fresh, I suppose. It’s still fundamentally Zen which is what I meant. It’s not a completely new overarching architecture like what was exciting when Zen was replacing Bulldozer and Co.

They will not, lol. They have comfortably settled in the consumer market, laptop chips are not yet going to be announced (I think?), so we have no idea if they will have NPUs. And the market that AMD truly cares about doesn’t get hyped by marketing buzzwords. They iterate on what matters - actual computing power and scalability.

Nice FUD right there.
AMD's APU's have had an NPU for over a year, while the upcoming CPU doesn't. You haven't figured out why?

 

[Neo_Morpheus]

I hope that they start including support for more usb 4 ports.

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.

 

[Denver]

This leak here is much more interesting.
Lower TDP for ryzen 7 and slightly higher clocks.

Because AMD didn't figure out how to hook it into any significant frameworks? Just guessing here...
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.

They do. We just don't see it much 'consumer-facing'.

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)

Indeed. Very few games utilize the potential of octa+ core CPUs. The non-entertainment workloads seems are in in much better situation, on both Windows and Linux.

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.

Though, I don't see how AI/NPU parts in these CPUs help for these very purposes. Might as well use the die space for more cashe, or die shrink instead, for the very much same amount of space these blocks occupy. Yeah, yeah, they want to be competitive in this AI race, where everyone contributes into this madness. But still. This is pointless for desktop, outside the Copilot/Recall BS dataminer

However homogenous 3D V-Cash layout in multi CCD SKUs would be highly apreciated, since the Windows scheduler is still a hot garbage. Just IMHO

IPC increases better be sky high as these clocks, cache and cores are identical to the 7000 series.

GCC patches for scheduling on Zen5 have already been published. Please find it and read it. What else do you need to know in order to conclude that Zen5 has about 20% faster IPC than Zen4? It is known for a fact that FP stores have, in some scenarios, 100% higher IPC than on Zen4, thus some FP-heavy codes can be expected to gain more than 20% IPC.

Yeah about as fresh as Core by now, let's not fool each other here. Grounds-up, so they recompiled it. Great Its still a Zen CPU. Grounds-up means exactly nothing, or about as much as nanometer processes now.

Zen 1 was grounds-up. This is another Zen CPU

AI 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.

If you had (which you don't) your own x86-64 CPU design, you made changes in multiple places in the core design, optimized the design, then "recompiled" the CPU design source code so that it is error free: wouldn't you yourself be claiming that it is a grounds-up redesign?

Of course, and I would also be selling bullshit. Every new gen is a new iteration of something built upon before. Calling the first Zen a real grounds-up architecture, I think is quite accurate, but even that is built upon decades of experience. And sure they heavily tweaked Zen by now, but it still is a CPU with an interconnect and chiplets in CCD's as its fundamentals. The cores itself can also undergo changes, but they're still tapping into that same overarching structure.

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.
