AMD Zen 4 Ryzen 7000-series and AM5 motherboard details leak ahead of Computex 2022

Summary

AMD's Ryzen 7000 series CPU details leak ahead of their official reveal. A lot of information has dropped about AMD's Ryzen 7000 series, arriving through Videocardz, who has managed to grab hold of some official AMD information ahead of the company's Computex 2022 keynote. AMD confirms its Ryzen 7000 series are to launch this fall. AMD also reveals its X670 Extreme, X670 and B650 chipsets for first-gen AM5 motherboards.

At Computex, AMD is expected to showcase X670E, X670 and B650 series AM5 motherboards, and reveal details about their planned Zen 4 based Ryzen 7000 series processors. These CPUs will support both PCIe 5.0 connectivity and DDR5 memory, with their LGA1718 socket retaining compatibility for existing AM4-compatible heatsinks.

 

AMD's Ryzen 7000 series processors are confirmed to feature 1MB of L2 Cache per core, a 2x increase over Zen 3, a greater than 15% single-threaded performance uplift and AMD has confirmed that their Ryzen 7000 series processors will boost to clock speeds of 5GHz or more. 

 

A leaked slide has also confirmed that their Zen 4 Ryzen 7000 series processors will support new instructions, including AI acceleration instructions. This likely means that Zen 4 support AVX-512 series instructions. In a slide, AMD has confirmed that their Ryzen 7000 series CPU chiplets will use Zen 4 cores and 5nm lithography. AMD has also moved their I/O die to 6nm (from 14nm with Zen 3), and had added RDNA 2 graphics.

 

AMD's Zen 4 Ryzen 7000 series processors reportedly use 8-core CPU chiplets, and it looks like AMD has no space to install a third CPU chiplet on the processors. This means that AMD's Ryzen 7000 series could max out at 16 cores. 

 

AMD will reportedly confirm at Computex that their Ryzen 7000 series CPUs will release in "the Fall". 

 

My thoughts

It's nice to get some decent information regarding Zen 4 ahead of Computex. Tomorrow most of this info will be confirmed, aside from what is already confirmed through these leaked slides. I'm hoping that the 7000-series doesn't max out at 16 cores as suggested. It appears all the websites that are covering this story still leave a question mark as to whether or not Zen 4 will max out at 16 cores. I'm wondering if we will get any info regarding this tomorrow. As far as AM5 motherboards are concerned, it looks like Extreme motherboards are a new addition. I'm wondering what they will cost, and if or why they are necessary. It's also nice to see an iGPU being confirmed too. AMD is really checking all the boxes with this release. Autumn can't come soon enough.

X670E seems interesting, a differentiator for the beefed out God tier motherboards. Now, what I would love for future generations is X670+, or something along those lines. MSI's MAX series of motherboards was really useful for recommending B450 motherboards alongside Ryzen 3000 series processors, due to confirmed BIOS compatibility. An official first party differentiator would be really handy for a future 8000 series of processors, when considering budget-friendly B650 boards.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

Any IPC uplift combined with that clock is going to really chew through work! Raptor Lake would likely not get much different clock so would have to rely on IPC uplift to fight back. It's going to be really interesting when they both are out!

 

Lack of rumoured 3rd CCD in the shown image is interesting. I wonder if AMD might still reorganise it to accommodate such, assuming the IOD has sufficient connectivity. It doesn't need to be a launch day product but can come later on if necessary.

 

The addition of iGPU to IOD had been speculated, and this could answer in part a question I had for a long time. What is the single CCD to ram bandwidth going to be like? Existing IF isn't going to be able to make use of DDR5 bandwidth synchronously unless you have at least 2 CCDs. I had wondered, would they go async as standard, would they upgrade IF from Zen 3 and earlier version(s), or do something else? That something else could be the iGPU, which can use all the bandwidth it can get. I really hope a single CCD can have fully bandwidth from DDR5 but AMD would have to essentially 2x IF from Zen 3.

X670 EXTREME 

What a silly name for a chipset. (I want it)

As far as AM5 motherboards are concerned, it looks like Extreme motherboards are a new addition. I'm wondering what they will cost, and if or why they are necessary.

I suspect these will be the halo products of this product generation. The $500+ top end boards used by extreme overclockers, YouTubers, and people who just have to have the best. For almost everybody else I doubt there would be any real incentive to buy over the X670 boards. The leaked slide image shows X670 having PCIe 5.0 graphics support with an asterisk which most likely will mean just the top x16 slot is PCIe 5.0 with the rest being 4.0.

From the way they're limiting PCIe 5.0 support on this generations motherboards it seems to me like PCIe 5.0 was more difficult to achieve than they might have expected. Recently a Z690 motherboard was recalled for issues with PCIe 4.0 and I imagine if board makers are having trouble with PCIe 4 then 5 isn't going to be any easier.

Interestingly, that's a PCIE 5 slot that's having issues running in 4.0. 

I wonder is PCIE 5.0 isn't going to be as backwards compatible as it should be. 

I'm not actually trying to be as grumpy as it seems.

Xtreme?? looks like they removed the capability to use APU on that chipset so less cluttered motherboard, make sense since nobody would buy a top of the line mb for a measly undercut APU performance.

 

I wonder if they can pull out a 12 cores chiplets. This means 4 cores is officially dead.

I'm also wondering if this means that there's still hope for a higher than 16-core product coming out (because the Extreme series AM5 motherboards existing and being somewhat required to support a higher than 16-core SKU properly). 🤞

A couple points to note:

The Zen 4 integrated graphics will be fairly basic, you can see the size of the IO die there isn't a lot of a die space for powerful graphics.

According to leaks:

X670E, X670 and B650 all use the same chipset die.

X670E and X670 have two of these dies on the motherboard.

B650 has only one die.

All chipsets can support PCIE 5.0 graphics and storage. B650 however has less IO so you wont see PCIE graphics off the chipset often.

 

So what's the difference between X670E and X670 you ask?

To call your motherboard X670E, PCIE 5.0 is required and all other ports need to be their highest possible spec.

Extreme chipset though. Gotta see that.

You need an extra 0 on that price tag. (only kinda serious, as there are already high end boards surpassing that for what presumably is not many good reasons)
