AMD Kaveri APUs Compatible With Socket FM2+ – New Roadmap Confirms Launch in Late 2013

[Boomstick777]

AMD is preparing a new socket known as “FM2+” for their upcoming generation of Kaveri APUs as revealed in a roadmap leaked by Computerbase. The new roadmap shows that AMD would launch their Kaveri APUs in late 2013 which would bring an updated CPU and GPU architecture to the APU platform.

So presumably backwards compatible with FM2 boards then?

APU with around HD 7790 performance..

Could be, they hint at FM2+ being DDR5 compatible, maybe FM2 will be used for DDR3?

Looks awesome anyway, SR and GCN..

But isnt the memory controller part of the cpu and not the motherboard, making this impossible? or am i completely mistaken?

 

[Martini1991]

That's the part you picked on, not the missing out of DDR4 ?

They could put DDR3/DDR4 memory controllers on the CPU, the board would still need to be able to fit it though.

AMD bringing out Richland then a new APU a few months later, I like it, but it's not very AMD like

We been promised DDR4 so many times now with no showing that ive forgotten all about.

As much as I'd like that to be true (progress is great!), I just can't see it happening so soon.

And they'd surely be eating into their own GPU sales if it was indeed that powerful. GPUs that are selling for £100+ currently...

Dont think it will tbh. Instead it might shift those on budget machines to use all out AMD in their machine. If this is the case and they are extremely succesful with it, developers might just optimize even further for the AMD architecture. This will echo throughout the entire AMD lineup from low end to high end. Of course this is all just speculation on my part.

hybrid crossfire with a 7790, what kind of performance would that get? must be around 7870 or 7950 level surely?

AMD gpu memory controllers have for several generations been gddr5/ddr3 compatible, they are very very similar memory and have a lot in common with each other hence the cross compatibility, hence the PS4 having gddr5 and the X1 being ddr3. Strictly speaking the memory controller is still very different and they could have added compatibility for whatever the client wanted.

Either way there are quite a few rumours that seem to be pushing the idea that Kaveri will actually support gddr5, its a way to significantly increase bandwidth though latency is hurt. Thing is I'm fairly sure both because AMD helped come up with(and since alter) GDDR5, there isn't any particular reason they couldn't make some new spec gddr5 with lower total speed but lower latency(IE you can get ddr3 with cas/ras/the rest 9,9,9 and 12,12,12.

They've made high latency but very high speed gddr5, probably no reason they can't tighten the timings significantly with a small speed drop and maybe bring it to a point where its worthwhile.

Maybe they just went and did a GDDR5, but more quietly, and came up with ddr5 with Samsung on the sly to bypass DDR4 which seems, meh and to be taking donkeys years.

AMD has already gone with a Jaguar architecture with unified gddr5 access, and KAveri is said to be fully HSA compatible. With the supposed architecture changes, flooding it with bandwidth and taking the hit on access latency will hurt it badly with mispredictions I would assume, but would keep a massively higher decoder flooded with instructions.

WE'll see, AMD is certainly doing some very interesting things with Steamroller and Jaguar.

EDIT:- didn't read the whole thing, I see the article says gddr5 specifically, not ddr5. If they are talking about putting a couple chips on die for not quite gpu cache, but that could be effectively used as such, it would certainly be interesting, particularly if its all unified meaning the GPU can use the higher speed memory when it needs to, but the cpu can use it when it needs to.

Thing is AMD/Glofo/industry in general is VERY close to using transposer's for putting dies together on package, using copper traces mm's away with the ability to cram craploads of traces in a tiny area for huge bandwidth vs off die to main memory traces cm's in length that use a lot more power and are much much slower. If they stuck a few chips on a transposer and filled the main slots up with lower bandwidth/lower latency ram it would certainly be interesting but I haven't heard an awful lot that suggests transposers are ready yet, though towards the end of this year, and at GloFo, who knows.

This gen is very interesting for AMD, but when everyone gets ridiculous bandwidth on die memory via transposers then later on stacking, they will make current chips look awful in comparison.

Most probably.

Methinks that early variations of these chips have already seen light in the next gen consoles

Usually its an indication, yes. Phenom II for example was an AM3 socket CPU, but also had both DDR2 and DDR3 IMC's and was full interchangeable between AM2+ / AM3 and AM3+

It needs to be around that performance considering Intel are claiming the new IGP on the Haswell is on the heels of a 7750.

Not really surprising, the A10-5800K is on the heels of the 7750.

Thats going to be a massive leap then. The IGP on pretty much any past intel chip has been terrible.

I wander if Intel would ever consider making a hybrid APU with Nvidia graphics to compete with AMD's. That I would like to see . Quad core Intel with Maxwell IGPU, I can dream lol.

Really do like these APU's, hopefully be good enough to not need dedicated GPU's in the future. Would make for some awesome small factor PC's..

I highly doubt that will ever happen, for a multitude of reasons.
But we can dream.

Unless I am mistaken, that is essentially how the PS4 and Xbox One will work, so the future is now.

That's consoles yuk , I'm talking about powerful Desktop APU's. Imagine how small the PC could be. Very cool stuff in the future..

I still recon that because of how video-game code is highly optimised for consoles, that the next gen consoles could offer better value for money than a comparatively priced (and probably a higher priced) PC.
