AMD B550 Chipset Detailed, It's Ready for Zen 3, Older AM4 Motherboards not Compatible

[Melvis]

If your systems can't last 7 months until the end of 2020, you have bigger problems.

That wasnt the point I was making lol the point was that you get 4yrs worth of CPU's to choose from and you can upgrade to said CPU in many yrs from now.

Nope, I would recommend to avoid the Ryzen 9 3950X unless it's a very cheap deal.
Ryzen 4000 is about to redefine the competitive landscape with groundbreaking IPC, clock uplifts, and better gaming and much better overall performance and offerings.

Well of course.....who would upgrade there CPU from a 2700X to a 3950X in just over a yr.....thats just silly, i meant in 4-5yrs from now.

Haha nice one! naturally its going to be better......but ground breaking? I dont think so.

AMD has to justify the high price of x570 boards, so they decided Ryzen 3 will not be supported on X370 and x470 boards. Otherwise it would make no sense to pay 200+ for X570 starter boards like the TUF Gaming, when the X370, X470 are lower priced and offer much more OC settings. This was my thinking when Ryzen 2 released. I bought a low end X570 with the mindset to jump on Ryzen 3 in the future.

 

[R0H1T]

The part thats even worse is I have built many clients Computers all mainly on the B450 motherboards and saying to all my clients you be fine all the way through till the end of 2020, got yrs of upgrades to choose from, now I look like a total lair!

That's not necessarily true, unless you said specifically zen 3 ~ in which case, yeah totally

Also remember Ryzen 4xxx would first start with the (zen2) APUs so technically you'd be (partially?) covered. Anyway the point is an upgrade to Zen 2, say 3950x, from Zen or Zen+ chips is a major leap & something like 4950x would be better though not necessarily more than 10-20% faster on avg than the current MSDT king. On the other hand 3950x will come down in price appreciably over the course of its lifetime, if history is anything to go by.

 

[zlobby]

What do you mean AMD won't confirm it? i thought this was common knowledge from day 1.

Yep, it's not just confirmed if there will be backdoors as in the previous versions yet. My bet is placed, however.

You have to read the Zen 3 microarchitecture updates. It will now have an 8-core CCX which should dramatically improve the gaming performance.

Informations are for 17% IPC uplift ON AVERAGE + 6-7% clock uplift.

I expect, fully expect the 12-core Ryzen 4900X to be as fast as Ryzen 9 3950X.

 

[Turmania]

I do not mind if both AMD and Intel releases a new motherboard with every genaration of cpu released as long as the new cpu's are backwards compatible with the older in the same architecture family of motherboards.If they change the architecture of a cpu yeah i agree on new socket and compatibility changes. Both Intel and AMD are doing it. Intel for this tenth gen should not have done it as well or at least release it but let it be compatible with z390 and etc. In short, they so it and getaway with it.none of them are your friends,there is no need for brand royalty unless you are on their share holders.

 

[tfdsaf]

I feel ya and it's why Ive recommended amd for most of my friends the last couple years but it's also why Ill be sticking with Intel.

I don't want to settle I want what's best and if I'm going to spend that money it's going to be what's the best value as well and my only measurement is gaming performance (it's a gaming pc after all).

Intel have stagnated and you'll need a new mobo for the 10k series of their cpu's, while if you wait a little, buy a B550 board, you will have future upgrade option with the 4000 series, with Intel you are going to have to upgrade mobo again with the 20k series or whatever they call it.

Sounds great but it better not be! or I will be even more pissed off

 

[1d10t]

I think it's weird if they release this B550 without anything to plug in, my bet some of motherboard manufacture are gonna support Zen 2 3000 series out of the box.

 

[oxidized]

Your expectations will never be met then , what comes next for AMD and Intel, you may know the names all else is gossip, no,. Specifications get released when the product does,, before then they are subject to change.
And before then they are a competitive secret.


At the end of the day they make what they can of the millions of chips and sell that then when they know what they Will do.

And then board maker's do whatever makes commercial sense not normally to help the user

With not owning one at least you can choose still chill..

Another thing if you bought a 3600X thinking of upgrades you do still have options ,a 3950X if you got that your probably sticking a year at least.

I have no personal expectations, i only base them on words companies say, i don't make anything up of my own. Getting a 3950X to replace a 3600X isn't an upgrade, it's different CPUs for different uses, someone that buys a 3600X isn't looking for what a 3950X can give him, he's looking for what a 3600X gave him but better.

Again with the total rubbish , your here because your personal made up bullshit skewed your perspective.
Your so stuck in said perspective you can't see common sense.
And now you know what everyone wants.
Your wasting my time.

Still no proof anyone at AMD garaunted every CPU on every socket.

Just your perspective.

Stick it mate ,you know f all, and are a troll.

It's not rubbish at all! That's not my perspective, it's everyone's! It's what AMD made everyone understand with "AM4 support until 2021"

AMD said AM4 would've been supported until 2021, but again what use could it be if i have to swap my motherboard regardless?

Wasn't aware X370's didn't support Ryzen 3000 series processors:

 

[deksman2]

AMD's excuse on ROM chip size being insufficient on older motherboards does NOT appear to be valid:

Here's a Google DOC comparing ROM chip sizes from B350/X370, B450/X470 and X570 mobos:

https://docs.google.com/spreadsheets/d/1wmsTYK9Z3-jUX5LGRoFnsZYZiW1pfiDZnKCjaXyzd1o/edit#gid=2112472504

As you can see, X570 mobos come with both 16MB ROM chips and 32 MB.
More to the point, even B350/X370 along with B450/X470 mobos also come with same sized ROM chips (depending on the mobo of course).

So, ROM chip size doesn't seem to play that much of a part... unless of course the microcode update for Zen 3 is so huge that it needs to eliminate every single previous Zen CPU (Zen1,+ and Zen2)... which is something I very much doubt because even X570's come with only 16MB ROM's.

Before Zen 2 debuted, a similar problem occurred, but it wasn't AMD who said they won't support it, it was the OEM's who created the problem of giving too small ROM chip sizes and packing the ROM's with graphically intensive UI's
But it was found that stripping those UI's to the more basic graphical representation freed up more than enough space for Zen 2 microcode updates on 16MB ROM's (which is what the mobo manufacturers did).

Heck, even my Acer Helios 500 PH517-61 has a Ryzen 2700 and Vega 56... its a desktop replacement with a proprietary B450 mobo that has a 16MB ROM chip.
Acer's BIOS/UEFI UI is rather basic (dates back to DOS style represenation), but as a result, mere 47% of the ROM chip is used... which is not even half.
Acer unfortunately stopped supporting this unit shortly it was released, so I never got a BIOS upgrade path to Zen 2 (even though they could have integrated it - and the cooling in this unit has been specifically reworked for AMD which means its running cool and quiet - even under maxed out load - so it would be able to handle both Zen 2 and Zen 3 - at least CPU's up to 65W TDP).

If ROM chip sizes are an issue for some motheroboards, why doesn't AMD leave it to the mobo manufacturers instead like they did before?
In the case of 16MB ROM chips, support for Zen 1 CPU's could be taken out (but warn users that those on B350/X370 mobos with this update and if they are still running Zen 1 would be advised to use a loaner/cheap CPU of say Zen+ variety at least which is cheap just to get through the BIOS update).

I believe the boards makers will give support for Ryzen 4000 on the X470 and B450 (MAX) boards, too:

You are right, it probably takes bytes to just add a string to the new CPU part number and the support to be there.

your on an i7 2600k you will have to swap your motherboard anyway. definitely, and ill let you into some advice I learned.

no matter what anyone says support past 1 year is not guaranteed EVER ITS DOWN TO THE OEM BOARDMAKER many of whom dont give the slightest of shits because they make money on NEW boards, support for upgrades beyond 2-3 years is exceptionally rare.< those are facts with no proof too.

AMD B550 Chipset Detailed, It's Ready for Zen 3, Older AM4 Motherboards not Compatible

Why is it that everyone treats AMD with a double standard? Nvidia jacks up prices on RTX, that's ok, but when AMD prices Navi similarly for similar performance, everyone gets hysterical because I guess they have an expectation that AMD, and only AMD, should sell them whatever they want dirt...

[ruff0r]

Id be lying if I said I wasn't a bit pissed off as I bought my X470 motherboard for exactly that reason for been able to upgrade to a 4000 series CPU in the future and this Motherboard wasn't cheap! If this does end up to be true then its not to bad as I can jump to a 3950X which from the 2700X is a good upgrade but still.....this wasnt the initial plan and If I knew this was going to be the case I would of jumped onto Ryzen earlier.....

The part thats even worse is I have built many clients Computers all mainly on the B450 motherboards and saying to all my clients you be fine all the way through till the end of 2020, got yrs of upgrades to choose from, now I look like a total lair!

The whole BIOS thing is complete and utter BS, you only ever update your BIOS for when a new CPU comes out so your mobo can support it, you dont ever need to update your BIOS to go backwards in CPU's lol you only do it for upgrades.....so if a new BIOS was out and it removed support for older Gen 1 Ryzen CPU's then who cares! your not going backwards anyway, and if you ever do for some reason go backwards then flash it back, not hard!

isn't Ryzen 4000 series just a refresh of the current 3000 series? that work in 90% of all boards? so what gives!

EXACTLY what i did with my friends, myself and my clients too... this makes me really angry.
I really hope some boards will be supported for the 4000 series.

 

[droopyRO]

Wasn't aware X370's didn't support Ryzen 3000 series processors:

I had to google it, but it depends on the mobo, some do have support for 3xxx CPUs https://www.asrock.com/mb/amd/x370 taichi/index.asp#CPU

Yes i already said that i'd have to swap motherboard anyway, i already said in a previous post why i'm complaining about this, besides the fact i recommended AMD in countless PC configs i made for people in these years, and who bought the crap 1000 series, might be left with a fistful of nothing and will have to swap everything, despite they bought 300 or 400 series.

So tell me why state you plan to support AM4 until 2021 in consumer addressed events, because i still haven't received an answer.

Saw it, and again if they come out and they're perfectly compatible it'll be best for everyone, but for now facts are telling us we might not see compatibility for 4000 series on <500 series motherboards

 

[TheLostSwede]

From what I've managed to dig out, it seems like there won't be any 4000-series CPU support on older boards, as AMD doesn't allow the board makers to enable it. This is still preliminary information, but it's what AMD has informed the board makers, so far. Not sure if this applies to APUs as well.

Saw it, and again if they come out and they're perfectly compatible it'll be best for everyone, but for now facts are telling us we might not see compatibility for 4000 series on <500 series motherboards

That was linked to the wrong post initially, see the corrected one above.

They are supporting the socket, AM4 is a socket nothing more never was.

You advised people wrong, send them my way next time I'm not deluded, I read information better.

We all here had these kind of arguments when x570 came out and x470 became the poor cousin in support terms a year ago.
