AMD Carrizo Pre-release thread

[Gideon]

It costs very little when silicon is done maybe it isn't competitive in the market or something

It does not cost 'very little' to have a SoC, designed with a Northbridge on board, work in a totally different socket. It's a lot more design/validation work than in the case of Kaveri for instance (where it is indeed quite trivial).

The other possiblity is to create a new socket and mobo chipset (FM3 or sth). They opted not to go that route, probably because it wouldn't be optimal for Zen anyway (maybe there is no socketed version of that or it will have 4 memory channels or whatnot).

We know from AMDs own statements, that they planned to do a FM2 version of Carrizo, we also know that it was going to have a max TDP of 65W. They probably looked at the validation effort and decided that those engineers would be better used on more profitable projects down the line.

And it sort of makes sense. At 45-65W the CPU will almost certainly be a sidestep. The GPU would probably be noticeably better, but that probably isn't enough to justify the engineering effort. I mean for desktops there is always the discreet GPU option. And for Mini-PCs and set-top boxes 35-45W BGA would be just fine.

Sure AMD's management made the most obvious choice to them I'm sure of that.

I just find it a bit odd because there is not that much that has to happen they have had the disable onboard enable dedicated chipset option in the works for some time. Extremetech wrote about AMD's plans for Carrizo. Maybe they made Carrizo so to cut down power but the interconnect logic needed was therefore removed.

Who knows I hope those BGA packages in desktop cases can OC

Since its AIOs, you can forget it. I doubt you can even change the cooler.

 

[DrMrLordX]

Cmon now, people figured out how to overclock BGA Iris Pro. It may take some UEFI hacking, it may be very very niche, but it will probably be doable.

It would not surprise me at all if Asus released at least one Carrizo board/CPU package capable of overclocking. The big problem will be HSF mounting since they will probably break away from the system they've been using on the desktop since . . . forever, and go with something closer to AM1.

No Chorizo for desktops, so FM2+ is done. Good job AMD, FM2+ owners will be very pleased with the support...

No Chorizo for desktops

I wouldn't recommend putting chroizo in your desktop. Stuff will stink after a few days.

i do recommend putting chorizo in your belly.

Does it mean GDDR5?

Oh, don't be so dramatic. AMD has already announced the 7650+ which is just what the doctor ordered: essentially, it's a 7700k with an MSRP of ~$105. Which is what I paid for my 7700k.

 

[NTMBK]

Does it mean GDDR5?

Doubt it. Carrizo is aimed at low power consumption, and GDDR5 tends to be pretty power hungry. Plus at the lower TDP it probably isn't memory bottlenecked.

Is it? lol Because this news has me looking to abandon AMD permanently. Wasn't expecting to waste my money with another future-less socket when i went from AM3+ to FM2+.

Hopefully AMD can give us something different like a lean and mean cost optimized hexcore without all the die bloating iGPU on board.

 

[inf64]

I doubt that will happen. Not with Carrizo since it's mobile optimized and will not make sense on desktop. Maybe Zen could be the core that makes 6 cores in APU possible but we have no data on what Zen really is and how it stacks up versus previous gen parts.

You're obsessed.

 

[VirtualLarry]

You're obsessed.

He's not alone. I would likewise like to see a three-module / six-core FM2+ part. With a minimalist IGP (booting, desktop, no gaming).

I know you mentioned Carrizo, but you must mean hexcore with Excavator cores right?

Yes, I figure a desktop hexcore would probably need to be steamroller based due to Excavator being a more mobile optimized design.

No way is this bd derivative compettitive here by a long stretch so why bother? That goes for sr as well as excavator.
Intel can release 6 or 8 core 14nm on the desktop with cost hardly visible if the chose to. Its just added cost for amd and they would even be thermally restrained !
Lets see if this mobile carizo can even make it to market where it is best.

 

[Lepton87]

On the Intel platform we are unfortunately either stuck with 4 cores or forced to pay up for their enthusiast platform with its completely unnecessary 4-channel DDR4 memory.

 

[stuff_me_good]

Good luck with the alternative... as far as my experience goes, they have even less future-less platforms.

 

[DrMrLordX]

From a cost perspective, it is. Kaveri chips have long cost more than people are willing to pay for them. If my 7700k is any indicator of what the 7650k can do, it'll be a steal at that price.

I echo the sentiment that a 3M or 4M Steamroller (or Excavator, but seriously, I think it would be more work for them to put together a chip like that) on FM2+ would be great for people who are looking for more modules and to replace FX. It's just that it may be too late in the product design cycle for them to roll out something like that unless it's already in the works.

There is also the question of whether or not they have the financial resources to produce a stop-gap solution like that to carry them to the Zen launch.

What we will probably get are Kaveri refreshes in fits and starts. There was the 7800, and now the 7650k. Next we'll probably get a successor to the 7850k with higher clockspeeds, and maybe a revamped memory controller. Maybe.

Carrizo will probably like Llano as in much better than the competition if you take into account CPU, GPU and their respective efficiency. Mediocre performance with the lowest possible power consumption are the future since making thinner laptops is important...

But I hope this time around AMD can mass produce it and it will see adoption rather than what happened to Llano.

We all know that a good keyboard with sufficient key travel is certainly worth 2 mm extra instead of lesser height. Carrizo could really be amazing in mobile I'd actually like to build myself a high end platform notebook with Carrizo if those double the efficiency claims are true. The board design alone however would already bankrupt me. (500 hours+ of work right there)

There was another Si soft score posted a couple of days ago. But it was so high that I don't believe that is really the case. For those that want to take a look here it is:

If 4-channel memory is unnecessary can't you just populate two channels?

 

[III-V]

Good luck with the alternative... as far as my experience goes, they have even less future-less platforms.

Intel platforms have trended towards having one initial line of processors, and a later line offered. They last about two years before Intel releases a new line on a new socket.

AMD's rate of integration and innovation is lower than that of Intel's, so they stick to sockets for longer.

now this is kinda interesting, i wonder what kinda deal intel had to make to get this?

how is amd expected to compete with this?

...you do know that AMD could get those prices too, right? It's "Bing for Tablets", not "Bing for Bay Trail". :\
