AMD Carrizo Pre-release thread

[erunion]

I dont believe they will replace Cat cores (Carrizo-L, Beema/Mullins) with Excavator.

Neither do I.

That bottom APU could be puma+, possibily carizzo- L refresh. Most likely 28nm.

 

[Maxima1]

If you going to port Excavator to 14nm then you can build a 14nm ZEN APU. Why spend resources, time and money to just port Excavator to 14nm when you have a better architecture ??

or

If you just port Excavator to 14nm, why spend resources, time and money to create ZEN in the first place ??

I dunno. Why did the APUs lag behind the GPU platform?

Maybe because Zen is a four core unit, recall the leaked slides, & Excavator can go down to two. It's also possible that Zen may just be server oriented & that tuning it for such low TDP (just like Intel core) will take some more time, also wan't K12 supposed to replace the low end? It stands to reason that if K12 was the successor to cat cores then Excavator might just be a stopgap solution till it arrives on 14nm or maybe 10nm.

Look like AMD has boosted Carrizo-L Puma s perf/Watt by a huge amount, improvement made the Intel way of course by allowing 12W chips to momentarly boost to 25W if ever there s a benchmark to execute...

[DrMrLordX]

Interesting, and not a bad price at that, especially since they kicked in an M360. Would be better with an SSD instead of the M360 and 1TB HDD but whatever.

 

[Abwx]

Curious that they sticked a GCN 1.0 384 SPs GPU along with the 512 GCN 1.2 SPs allegedly provided by Carrizo, AT predicted the thing, though.

Meanwhile given the timing of the announcement and the fact that AMD is specifically advertising these GPUs as supporting Dual Graphics mode with AMD’s A-series APUs, I suspect some of these GPUs may be intended to work alongside AMD’s Carrizo APU, which is due this year.

Without this GPU price could be cut by a few dozen €/$ eventualy, otherwise base clock is at 2.1 and TDP 15W, but it will boost up to 2.8-2.9 on all cores if there s enough thermal headroom to acccomodate 10 more watts.

 

[DrMrLordX]

Hmm, R7 M360 = Oland = GCN 1.0

A bit odd, but it could still be useful.

Yeah that kind of chip would be perfect for some starcraft 2 or similar on the go.

 

[el etro]

Carrizo GPU, even on DDR3 Dual-Channel, is much better than the M360 Videocard.

 

[DrMrLordX]

Exactly, it's probably there for dual graphics. Might come in handy for DX12/Vulkan multigpu.

 

[frozentundra123456]

Carrizo GPU, even on DDR3 Dual-Channel, is much better than the M360 Videocard.

I really doubt that, unless it is some niche app that uses HSA. M360 has 384 shaders compared to 512 for Carrizo, but the M360 is clocked at 1ghz. I dont think they can clock Carrizo nearly that high and fit it into a 15 watt TDP, along with a cpu. Carrizo could actually end up being slower, especially if there is any throttling under heavy cpu/gpu load.

 

[AtenRa]

R7 m360 only has 64bit memory of DDR-3 at 1000MHz. Carrizo with DDR-4 2133MHz 1.2v will be faster.

have those memory specs been confirmed?

 

[AtenRa]

You mean from AMD ?? They have only confirmed Carrizo will support both DDR-3 and 4. DDR-4 starts at 2133MHz 1.2v so we should expect Carrizo to at least support this one.

 

[JDG1980]

I would be very surprised if K12 actually happens. It isn't compatible with existing software, and doesn't meet any market need that I can think of. I fully expect this to be axed.

After they displayed it as a 2017 product just two weeks ago..?.

K12 is essentialy a Zen core, as aknowledged in the slide below, and its design is already completed according to an SA member who has been reliable so far.

Doesn't mean it won't be axed before seeing the light of day.

Plenty of completed projects never get out the door, when reality sinks in.

Just like Skybridge.

 

[cbn]

So FX-8800P has a clock of 2.1 Ghz?

VR-Zone reports this as the turbo clock (with the base clock @ 1.7 GHz)---> http://vr-zone.com/articles/amd-fx-8800p-flagship-carrizo-mobile-apu-3dmark11-scores-leak/87542.html

But that doesn't seem right when I compare to the Kaveri mobile clock speeds:

Side Note: I do realize Carrizo integrates a limited FCH, but I can't imagine the TDP contribution from this integration reduces available power budget for the cores that much.

 

[Abwx]

Not due to AMD, lack of process is the cause, K12 will use 14nm when it will be much cheaper, think about it..

Yes, although this one seems an offspring of Zen when the general opinion was that it was the reverse, as such it isnt an expensive design as stated in the slide, i think that s the main reason that should make it a realistic product...

Anyway that s not the topic exactly, but since there s few news currently....

As already said it has a 15W TDP but will boost up to 25W with all cores, and likely up to 2.8-2.9, it is up to the OEMs to use or not the higher profile, the chip is TDP programable apparently, same as Mullins whose TDP can be set at mW precision.

Thanks for clearing that up.

You re welcome...

The TDP scheme on Carrizo is rather interesting as these chips are allowed to consume significantly higher power for short periods of time.

12W = 20W maximum
15W = 25W maximum
25W & 35W = 42W maximum

 

[el etro]

AMD should so much make a 45W Mobile Carrizo. Beting on premium laptops is a game they have nothing to lose. Will be exciting to see where Carrizo power efficient improvements can take the APU.
