AMD Carrizo Pre-release thread

[coercitiv]

If this would have been a Notebookcheck test, someone would blame them instead AMD/OEM. Sometimes it isn't this easy.

Notebookcheck also noted this. In the image bellow, except for the turbo boost interval, CPU ran at 1.3Ghz and GPU at 430Mhz. However, note the results are quite good for IGP in a 15W chip, once can check the Diablo 3 benchmark to compare (search for R6 Carizzo then compare with other results)

 

[-sandro-]

so basically what are we supposed to do to decide if this chip is any good without reviews?

AFAIK with the info from that slide the general consensus was they could still make up to 45-65W desktop APUs out of Carizzo. (Excavator starts losing to Steamroller after 20W per module, so for a mITX build they could go 45W for the CPU alone, 65W for combined load). There's also a FCH in there requiring some juice, so it all adds up nicely.

I think they've segregated the graphs, so you probably need to combine them somehow to work out where perf/watt parity would be. Specifically as the leakage graph suggests a 10% freq advantage that remains "off the chart" so even at ~22W/module where HD library and AVSC advantages cross over, leakage is still giving you 10% higher Frequency/w . Seems the parity point would be more like 30w/module. Leaving you with only the IPC gains over Kaveri.


What's unknown is if they will tweak Bristol ridge to scale to higher TDP.. After all it is some time away still.

I had so many hopes from this "carrizo" thing when I first saw the AMD's ppt !
now, it turns out its just a wild goose chase:$

how so? We have only seen 1 device. The hyperbole isn't cute.

I don't know. According to that NBC review, the CPU performance only seems to be on par with the Broadwell i3's and the GPU performance with i7's, so you can't say they're lying when they they claim it competes with low power i5's.

I'm a bit worried about battery life, however. Those 3 hours the HP Pavilion gets are abysmal. Worse than a gaming laptop with the GTX980M and the 47W i7-4710HQ.

AMD promised "all day unplugged performance" and "8 hours of video playback", yet someone on youtube commented he's only getting 4-5 hours of web browsing and some youtube on his HP Envy which doesn't have a dGPU.

This waiting game they're playing means the Carrizo devices won't get to enjoy their small window of being competitive. Very soon, they will get a in a direct fight with the intel's Skylake which is supposed to bring 30% more battery life and 40-50% more iGPU performance. Even though these claims proved to be false after its desktop release, if a Skylake i5 notebook gives me an extra minute of battery life over a similar Carrizo notebook, Skylake will be my choice without hesitation.

hahahaha... I LOLed like your Avatar......^_^

dunno what to say mate, I'm just disappointed with AMD.
Its relying/clinging on the old stuff/tech/minds... AMD should have moved on a while ago....
now Its just hibernating while Intel keeps on stomping over it.
If AMD has made something wonderful & intuitive (like "carrizo" (according to their ppt)), then why hold back on publishing and marketing the stuff ?!

On the technical side that have said all that they can say about it, as for marketing I really dunno man.

 

[ShintaiDK]

Its been the same story for almost 10 years with AMD. Why do some people still fall for it?

Fool me once, shame on you. Fool me twice, shame on me. But we are way beyond that.

 

[jime1]

AMD is just very lenient with the CPU/APU stuff. like always..
It just concentrates on the GPU stuff which might be innovative but still cant fairly compete with the only other competition ie - nVidia !
I understand that AMD has expertise in both CPU & GPU field and that it competes with both market leaders Intel & nVidia in the respective fields..

It is just not organized well enough to work efficiently with both the CPU/APU & the GPU stuff at the same time. AMD shouldn't have bought ATi !!
now look at AMD, its like its in the middle of nowhere.. not good enough at the CPU/APU stuff and now hardly good enough at the GPU stuff !!!
AMD has to get their sh!t together and start making some productive decisions, or else its going to sink big time...

AMD is now busy loosing its minds and fooling themselves surely !
No doubt, its "wayyy beyond that"

That is the definition of "wild goose chase" --- looking for something that you cant find. I do almost feel bad for AMD though, that there aren't more (any?) well designed Carizzo platforms on the market. But again, that is part and parcel of designing and marketing a product, so I dont know how much blame AMD has to share for this. My impression of Carizzo is that it is a decent product, but as usual the hype train got carried (not by you) away to levels that it could not possibly achieve.

I did let the hype carry me too much, not much can be done about amd imo. They are still in a holding pattern.

NBC review show that it is better than the competition, check the Intel comparisons in the reviews, 14"s that consume more, a 5200U with no review to back the numbers and so on...

 

[jime1]

Have a good night y'all, God bless all the Advanced Micro Devices !!

I don't think anyone here disputes it's level of performance. We are speaking to its availability.

Carrizo and Carrizo-L are socket compatible.

Prepare (and we are already seeing it) to see a TON of crapbooks designed for Carrizo-L with Carrizo thrown in. TDP limited at 15-20W and possibly a mobo designed only for single channel RAM.

And or course build quality aimed at the beema/mullins end of the market.

Makes sense in the same way that you don't see high-end sports car bodies paired with the engine from a Volkwagen Beetle.

A mobo designed for single channel RAM with x86 processors? Usually the cheaper notebooks just have one of at least 2 sockets populated.

And long as there is a market for such quality, it will be served by the OEMs.

I think you have your analogy backwards. Putting an 8800P inside a laptop designed for a 12-20W TDP and limiting the APU accordingly is like taking a 200-250 hp turbocharged engine and throwing it into the body of a Suzuki Cultus/Geo Metro/Pontiac Firefly, which is also something we don't see in the auto world.

The 8800P is small, efficient, and (for its TDP range) powerful. It deserves a proper home where it can operate within its full TDP range.

Yeah car analogies, Carrizo is like the brz/frs, having a decent motor and being hampered by skinny Prius tires.

Yet another round of urban legends...??.

What about reality..?.

FYI the king of craptop is Intel, they are spending 4bn/year to make sure that this crown belong to them..

Of course some fud was necessary..

PCB is the same, why should there be single channel Carrizo..?.

You think that OEMs are that stupid to eat in the negociable price of their gear by the dozen $ just to save a few grammes of plastic that are worth 0.01cts..?.

Ha ha! Ouch.

I think the fr-s is meant to be able to quickly/easily kick the rear end towards the outside of a curve for drifting, so smaller contact patch probably makes that easy . . . but for anyone who actually wants to go from point A to point B as quickly as possible, that = teh stupid.

Seriously though, there's a reason why the lower-tdp Carrizo chips have fewer GCN cores. If you limit an 8800P at the socket, it's going to take clockspeed hits on the Excavator cores more-heavily than would a 384sp Carrizo. The balance of power load shifts when you have more active GCN cores.

They really should not use the 8800P without giving it the full 35W TDP.

Looking at that list, it strikes me as amazing how many AMD laptops there are listed on that site, compared to what you see on American websites.

One of the things we may be experiencing here is that (yet again) AMD is having problems getting OEMs to carry their products in North America. If anyone is going to have an unhampered 8800P laptop with sensible amenities, it'll probably show up in the Eurozone first. Why? I do not know.

 

[Abwx]

35W + rest of system (excluding the screen) will get you up to 45W within the laptop casing, those could eventualy find its way in medium sized AIOs but for laptops that s too much even for a 17".

Those TDPs existed in those formats only due to CPUs not being powerfull enough, currently perf/Watt improvements are exclusively invested in reducing the thermal footprints as it s more rewarding $ wise, less costs with same selling prices....
