Is AMD 5000 series the last on AM4?

[Daylight_Invader]

yeah that can be ignored tbh. They said it would take similar for PCIE 5.0 that ended up being almost 2 years to finalise. And even if it is then you are still going to be a good couple of generations away. I mean we have almost completely skipped 4.0 in consumer parts, certainly on Intels side. We may see it quicker in server side etc but yeah just not in anything we are looking at for I think about 3 years from now. With that, does it really add anything for consumer other than cost. We don't for most part saturate PCIE 3.0 even.

I don't disagree. Added to which, I don't want to think about what the potential power budget impacts might be. These new techs will only be worth looking at when we get to some significantly smaller nodes, otherwise the power consumption issues may overshadow any gains one could get.

Whilst its good that the specs are advancing forward, it is countered by whether or not its actually needed. As above mentions, by the law of averages, we dont really make the most use of the PCIE 3.0 ... so to many folk ... whats the point/need ?

.... As it is, I don't believe Renoir (Ryzen 4000) supports even PCIE 4.0, which is rather telling.

My case in point ... A renoir with its built in GPU is far less likely to be paired with a discrete GPU ... and far more likely to be an all rounder machine, which 3.0 serves perfectly well mostly.

A lot of Renoir laptops (majority in fact) seem to be paired with Nvidia RTX GPUs. The new 5000 series laptops just starting to come out even more so!

I thought about this coming from 4790k but my thought was cost of DDR5, maturity, stability and all that because generally a first gen with new everything is going to have some teething issues and since even AMD on 5000 series has teething issues that is a good few generations in on a current socket I wouldn't want to buy into the latest myself. In fact if I hadn't picked up at retail prices I would have waited for the new CPU's from AMD and then brought 5000 series then when it would likely show a discount etc.

Edit: And if it does end up being a winning formula then I could offload my 5000 chip, mobo and RAM at a fair price to cut the costs a little but hoping to wait for a second generation towards end of 2022 if all on schedule.

Yes this is all very true. I was partly being a bit silly with my response. Currently the main thing holding me back from upgrading is the general unavailability of CPU's and GPU's. I know the 1080 is a very good card still, but I am looking to go to air cooling and my GPU did not come with an air cooler (preinstalled water block).

I agree that it might not be a great idea to immediately jump onboard with DDR5 as there will be the early-adopter tax for sure. Not to mention the unforeseen reliability and compatibility issues.

I am in pretty much exactly the same situation as OP. I would love to upgrade to a 5000 series Ryzen, but at the same time I don't really want to be on the last gen of the socket, especially if the rumours of DDR5 have any merit.

DIAMOND hands on the 3770K!

I very much think that any new socket will be introduced because of DDR5.
However, early adopter's prices for DDR5 will most like not be any better than the price premium early adopters paid for DDR4 and DDR3 before (etc.).
It might be as large as: buy AM4 now with 2x32GB for the same price as buying AM5 with 2x16GB. Plus early DDR5 probably won't increase speed much over current DDR4. All previous DDR generational switches had top-end previous gen almost as quick as the next gen mainstream.

We don't know but there are rumours that AMD is so unimpressed with Intel's Rocket lake performance that it is delaying Zen 4 and instead launching 6000 series as Zen3+ and it will run on AM4 boards.

This kinda makes sense, if the Zen 4 rumours are true it's going to be blindingly fast (like over 800 points in Cinebench R20 single thread) and extremely overkill for this market when Rocket Lake is sitting at 560 single thread points - so until Intel produces something with substance AMD seems to be taking it easy

Sounds very dangerous.
What might happen is that they delay the release a bit to polish any niggles and build up stock. Both things they've historically been poor at, and both things OEMs would actually appreciate (but not as much as yearly cadences to sell "new" stuff as OEMs are the main drivers or rebrands.).

I'd really like to know this.

AMD said they would support AM4 upto 2020, does this imply AM5 for 2021? I'm not sure

 

[andy_mk3]

Nothing is set in stone yet. But with the new CPUs being on 5nm it is likely that AM4 is at an end.

I wonder if DDR5 (+DDR4) could be supported on AM4, with new motherboard chipsets?

 

[KompuKare]

I would imagine the pin-out is far too different for that to work.
And the other solution of having a new short term socket (AM4+ or AM4.5 or whatever), able to support both DDR4 and DDR5 might be too much work although with the IO chip approach AMD are actually in a good position where they could "just" change the IO chip and keep the current chiplet.

 

[Cyber-Mav]

Zen3+ sounds good on am4 if its the chip that can sort out the problems with current zen3 cpus.

 

[Donnie Fisher]

I don't see that happening or being possible. Whilst the memory module will be the same form and number of pins as DDR4, the pin out is definitely different and the way the memory channels work are different. Its a different architecture and not just a bump in specs.

Also, it appears that the voltage regulation is moving from the motherboard onto the memory DIMMs ... which strikes as something to make DDR4 / DDR5 compatibility on the same board unlikely as well.

DDR5 on existing AM4 boards is impossible

Definitely disagree with this post. As Donnie mentions above, this is effectively impossible. DDR5 uses a totally different pinout to DDR4. Hopefully this post from Rambus (remember them?) helps explain key differences which will make it obvious as to why the pinouts are totally different:

The last leaked AMD roadmap says Warhol will be on 7nm (which makes sense since Apple have 100% TSMC 5nm for this year)

Eh? I said I think any new socket would have to be introduced because of DDR5 as there is no way that AM4 could ever work with DDR5.
