AMD Carrizo Pre-release thread

[lefty2]

Does anyone know what the official AMD roadmap is for Exclavator/Carrizo? Has AMD even officially mentioned Carrizo?

[NTMBK]

The embedded version, Merlin Falcon, is also in their slide decks.

 

[ph2000]

so it will be mobile first ?
wondering about user availability though

 

[lefty2]

Thanks for that.
So, officially AMD says Carrizo launches at start of 2015, not 2014.
Normally, it's about a year between APU launches, but Carrizo is only 6 months after Kaveri mobile, which launched this summer.
I wonder if OEMs are going to need more time to shift their Kaveri stock before they start up with Carrizo.

GlobalFoundries will have 7nm ready in 2017.K12 is coming out in 2016, Zen is coming out 2016+.

This is based on a GlobalFoundries Roadmap? You should add 3 years.

Retailers still have IB and Richland laptops on sale, if that says anything (and I'm not really sure it does)

It's still almost impossible to find a decent Kaveri notebook with a 1080p screen. I can't imagine Carrizo being available before 2015.

not impossible just limited, expensive and hp []

Since, 2012 and maybe 2013. There has been no mention in AMD's HP core roadmap of Excavator. While, there has been several roadmaps showing Excavator in products.

Steamroller was presented in hotchips 2012. It has also been shown to release in 2013 which it never did. Excavator was never presented in any such presentation.

You must be either blind or live in America then...

Lenovo, Acer, HP and MSI all offer 1080P Kaveri notebooks. In the 400 to 800 euro price range. That is in Germany so Europe actually has a decent offering of Kaveri notebooks.

It's just Intel bribes the American market far more than it does the European market and I recently spoke with a Chinese friend of mine seems like Intel is also bribing a lot in China.

Sue Intel for anti-competitive practices again because they never paid the price! Made over 100 billion profit for being in an almost monopoly position. Paid only 3 billion in fines. Crime pays for Intel and thus the consumer is forced to pay extra!

lets not go down that route in this thread, also nice finds but have you seen any kaveri subnotebooks less than 13"?

 

[maarten12100]

The only ones I have seen were the very expensive HP ones. Too bad really because my sis would be in for a small notebook. Guess she will be treated with a 5y10a based 13 inch notebook unless Carrizo brings something to the table bellow 15 inch.

I myself will receive my Kaveri notebook shortly it was cheap and I wanted something to play with. See whether dual graphics has improved I might keep it if it is better than my current Beema notebook.

 

[Ajay]

No, everyone rather take a dump in your thread.

Sorry if I came off as being harsh.

 

[NostaSeronx]

I think if the American market was not an act of anti-competition. It is actually from the close proximity of Kaveri mobile launch; June 4, 2014 and Carrizo mobile launch; December 2014.

Six month delay to get something more efficient. Not a bad choice in regards of planning.

AMD will disclose Carrizo, an integrated processor with its latest x86 core. The 28 nm chip measures 244.62 mm2 and packs more than 3.1 billion transistors. Its new Excavator core is 23% smaller and uses 40% less power than AMD’s previous x86 core.

No surprise, 28nm is the node for Excavator. A bit surprising are other numbers tho, compare with SR:

AMD Kaveri GF 28nm SHP 2.41B 245 mm2 9.837M
AMD Richland GF 32nm SOI 1.30B 246 mm2 5.285M
AMD Llano GF 32nm SOI 1.178B 228 mm2 5.166M

Looks like the HDL achieved the density increase (28% more transistors with basically same die size). Dunno why AMD cites the lower die area in the paper when Kaveri is right about the same size as Carrizo. Also I doubt they went for SP count increase due to mem. BW woes they have and will have (DDR3 dual ch.). What they spent those additional transistors on is unknown for now.

Power draw claim is also a bit odd, they state 40% lower power draw but under what conditions is unknown. I very much doubt that Carrizo will clock anywhere near Kaveri and draw so much less power. It's probably the numbers they got when comparing the mobile parts running at very low clocks where Carrizo might get such an advantage over Kaveri.

There s quite a lot of enhancement but a big part is devoted to the FCH.

Neverless the performance delta was stated at 15W as being 30%, this match with the 40% lower power draw, assuming a sizeable part of the perf delta comes from frequency uplift.

In STMicro's case in 2012; http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=6241805

In this paper, we present TDDB, HCI and BTI reliability characterization of Nfet and Pfet devices issued from FDSOI and bulk 28nm technologies. 28nm FDSOI devices achieve 32% improved performance, 40% reduced power consumption and improved matching. From device level tests, 28nm FDSOI also demonstrates intrinsic reliability behavior similar to 28 bulk devices, giving confidence in the robustness of this technology.

Don't make me go looking for FD-SOI shrinking 23% area. I can find it, I typed it out, I know where I posted it.

Speed @ ISO Power; ~30% higher performance
Power @ ISO Speed; ~40% reduced power consumption
Area Reduction; ~20% smaller
to bulk.

----
28-nm Carrizo -> 20-nm Carrizo for perfect shrink;
28-nm - 244.62 mm²
20-nm - 134.92 mm²

~245 mm² on 300 mm -> 235 dies per wafer
~135 mm² on 300 mm -> 439 dies per wafer

Decision to stay on 28-nm does not compute.

Maybe the HBM on Carrizo rumors were true and that Sisoft bench was correct.

Also, does this invalidate Carrizo-L in december?

Nope, Steamroller/Kaveri showed up in ISSCC 2014.

The trend is on ISSCC 2015, Excavator/Carrizo.

 

[geoxile]

So then when are we going to get info for Carrizo-L?

 

[NostaSeronx]

So then when are we going to get info for Carrizo-L?

November 18th, 2014 via Matt Skynner, corporate vice president and general manager, products, client and graphics business unit, will present at the UBS Global Technology Conference, or December 9th, 2014 via Mark Papermaster, senior vice president and chief technology officer, will present at the Barclays Global Technology Conference.

This is if they want to have a stronger launch than Kaveri. http://twimages.vr-zone.net/2013/10/螢幕快照-2013-10-27-下午8.56.54.pnghttp://www.sweclockers.com/image/red/2013/10/27/Kaveri1.png

Is the new integrated FCH included in TDP/power consumption measurements?

Yes. It should be included since it creates heat when used.
