So the AM555 meme is dead 🙁
RIP futureproof potential, this seems like it will have the same faith as 300 series chipset. Fastly becoming obsolete

actually great news for consumers and people who already have pcie 4.0 peripherals. this will help drive down the price for pcie 4.0 m.2 and ease the transition for AM4 users.
pcie 5.0 is great theoretically but in reality it's being used for marketing for Intel

Why is my chipset obsolete?
3000GB/s read and write is good enough for me on PCI 3 x4.
A 6900XT would also run just fine on PCI 3 x16.
I am limited to 3000 series CPUes unless I risk it with beta bios for 5000 series, but that is really the only thing bad about 370.
PCI 4 could deliver 6000GB/s or 2 3000GB/s disks.
The x16 GPU slot could also be parted up to 2 times x8 and deliver enough for 2 6000GB/s disks if needed.
Remember there is also Threadripper if the mainstream platform is too simple for you.

What future proof? People want a new cpu every 6 - 12 months here.
And they want to
In all of this pci express connectivity is the last of your worries for future proofing

intel got sloppy and amd got greedy
but you can't step into the same river twice
people like to throw in the word obsolete so that they think they're smart,without giving it much thought
what is obsolete:
4/4 cpus
gcn and kepler gpus
what is not:
3900x + 2080Ti system on a 970 Pro drive
D1stRU3T0R
Gcn obsolete? Vega vii is obsolete for you? I guess we have different meanings for that.
About Intel / amd well kinda right, but it's really sad that Intel COULD do it meanwhile AMD, the company that usually brings something new to the table, is failing even a popular meme.
cucaulay malkin
fury x has already gone legacy
D1stRU3T0R
Well kinda yea, but doesn't mean that it can't be used.
(and unofficially you can still install it :P)
cucaulay malkin
well,4g crippled it well before that

Why would anyone need PCIe 5.0? I'm using 3.0 and its blazing fast!
Very little people have upgraded to PCIe 4.0 yet and AMD has experience with it, why do 5.0 so soon?
This will help build the peripheral adoption needed to lower prices, and we will get more and better products.

gcn is pretty much eol at this point, it is basically at the same stage as late terascale parts were in 2013 , they still ship gcn(vega) in apus, but that wont be for much longer, the radeon 7 is approaching 3 years old, there will be driver support for a while longer, i wouldn't expect much past 2023.

PCI-E 5.0 would have been greater. But the only thing I care about (for my usage) is if it's bottlenecks gaming. ( so, if it's bottlenecks the dGPU I'm using or will be using with the build).
I think PCI 4.0 x16 still has several years to go.
As for storage. I don't really care about sequential speeds. I do care about all the others.
Considering how the GPUs are evolving. I think I'll need to wait more than 10 years to need PCI 5.0 to get a benefit in gaming. (I hope I'm wrong)

I don’t think a lot of people realise the physical requirements for PCIE 5.0 are very complex especially in ATX form or even smaller.
Not even mentioning it is utterly useless and very expensive for consumers or even prosumers, only datacenters can make use of it. I wouldn’t expect PCIE 5.0 to become a consumer standard until 2025 or even beyond.

A bit shame, but perhaps it doesn't do so much for directstorage performance. I doubt GPUs have any use for PCI-E 5.0 for a long time.

Technology needs to develop, but it'd seem somewhat premature to be moving to 5.0 already when 4.0 is still so fresh and underused. Intel failed to implement 4.0 with the 10th gen, only getting it working with the 11th gen, and AMD as well had to compromise with the chipset designs to get it functional. It feels like 4.0 NVMe SSDs started to appear in significant numbers only this year, and remain more expensive than the old 3.0 ones. All that being said, 4.0 wouldn't really need to last as long as 3.0, of course. But from my layman's pov, perhaps AMD and Intel would benefit from perfecting everything about 4.0 before reaching for the moon once again.

I couldn't care less that it doesn't have PCIe 5.0. 4.0 had some practical advantages over 3.0, even if the x16 slots still aren't necessary, but we're still several years away from saturating 4.0 to any degree that actually matters. SSDs are the only thing that could possibly saturate all that bandwidth, but if that's the case then just get a x8 or x16 SSD instead of a M.2.
What I think is more of a problem is that they're sticking with dual channel memory. For desktop CPUs, that doesn't really matter, but this will matter when it comes to APUs. DDR5 is a step in the right direction but I don't think it'll be enough.
Kaarme
I wonder if something like 1GB of HBM within the CPU, among the chiplets, as a sort of L4 cache, could replace increased memory channels?
Edit: I forgot AMD was already experimenting with the 3D packing to add a massive (?) cache.
schmidtbag
The problem with that is the chips could become really expensive.
Valve managed to get quad-channel for the Deck on an APU, so, it's not like AMD can't achieve this for a reasonable price.
I didn't hear whether AMD was doing 3D stacking, but I know Intel is, and AMD knows that if they want to stay competitive, they'll have to do the same. I'm still curious how that stacking will work in terms of cooling. Intel lapping their dies was enough to keep clock speeds higher on their 10th gen CPUs. You can't lap the transistors though, and unlike that top layer being shaved off, the additional transistor layers will produce heat. Sure will get interesting, that's for sure.

Good to know, though, this is a bit a way away from the 1GB HBM, or what Intel is doing with Foveros. It is a great step forward though, and I imagine caches don't run as hot so stacking them shouldn't e a problem.
