At this point , even with competitive products amd doesn't stand a chance with oems. Intel is doing something to incentivize them to use the super crappy celeron branded atoms in every single product category. It can't be Bom costs or power or availability or performance.

Intel must be buttering up up oems for them to drop amd so hard right after they all flooded the market with bobcat craptops and netbooks.

Again, you try and blame someone else but AMD and create some false scenario for it to be true.

Yo....could we like...not derail this thread? I would very much like it if this could be a thread where new information about Carrizo can be exchanged instead of a generic AMD sucks vs Intel sucks conversation.

God knows the internet has enough of these...and hating on either chip manufacturer doesn't serve any purpose.





Edit: An article on a german site once again stating a few infos which we mostly know. I'll just quickly rerun anything said in the text....the pictures itself were already posted. Link to German article.


During the International Solid-State Circuits Conference (ISSCC) February 22nd AMD will talk about (big) Carrizo officially. Some unofficially communicated information consists of:

-30ish% raised transistor count. (3.1 Billion vs Kaveris 2.4)
-The Excavator cores are 23% smaller
-They need 40% less energy than Steamroller
-Process will stick to 28NM and is very likely HDL
-Soc Style integration of Southbridge functionality for BGA version.
-Since cores are smaller but transistor count is actually up, those will likely be used for other things. GPU expansion, Integration of I/O like USB/Sata (Mobile Carrizo...again...more toward SoC style)
- L2 cache shrunk down to 1MB per Module. (This only seems to be confirmed for the smaller models, no word about the big brother)
-Official Carrizo-L presentation still expected for december
-Big brother Desktop variation still likely to happen in Q1 2015 (release after presentation during Feb 22nd)
-GPU is "Next Gen"
-DX12 support (well...duh), full HSA support, HDMI 2.0, Delta Color Compression


I think this is mainly just a rerun of all the information we already had but I just listed it again, anyway.

Problem is, perhaps Mullins is not nearly as good in terms of performance and battery life when packed inside thin/light/cheap 7-8'' tablets like Bay Trail or ARM SoCs and on top of that it costs quite a lot more than BT, but this idea might hurt the fanboys thinking it's the second coming of Christ.


6-8h battery life, with the higher powered u6700T, with a 32Wh battery and much better perfs overall than BT, this should be enough to get a sizeable part of the W8.1 tablet market but it s not possible because people just dont realize that Intel is flooding the market with 40 millions subsided chips, to give a perspective that s twice AMD s whole mobile shipped APUs, no wonder that their mobile shippement decreased 16% last quarter at the very moment where Intel shipped 15 millions subsided BTs.

We ll see how it turns when Carrizo is released, this one has the core M as weak opponent and this latter can hardly be contra revenued...

I wonder how badly the cache reduction is going to hurt performance.

I wonder what the purpose of it is. Because they keep the die size and even increase transistor budget. And its not like they have anything to write home about already in terms of CPU performance.

The HP Stream 14 use a 14" screen that has twice the surface of a 10"6 tablet screen.

Anyway i like notebook check review that state that :

there are notebooks with significantly longer battery life, for example, the Packard Bell EasyNote TF71BM-C8R1
Without specifying that the Mullins based LT has :

32 Wh Lithium-Ion
While the PackardBell BT based so called better lifer has :

53 Wh Lithium-Ion
65% more battery capacity for 40% more autonomy...

Also AMD has a take or pay agreement so they have to buy chips or pay a fine. Also GF is manufacturing cheaper than Intel I suppose. Clearly Intel can just discount their chips as much as is needed.

Do you think that Globalfoundries can manufacture a chip twice the size of Intel 2C processors and have a profit for less than Intel manufactures its 2C chips?

I think it's extremely unlikely that they'd create a die with more or less cache than another. Tens of millions of dollars (are we at hundreds now?) for new mask sets is simply not economical.

They could disable some cache, but that doesn't seem likely. Slimming down on L2 is not necessarily a bad thing. We will have to wait and see.

Yes,

Intels 14nm is way more expensive today than GloFos 28nm. Also, half the die size means double the volume that you should sell. If you cannot sell that higher volume you will have to lower your margins thus lower your price etc etc. If you cannot sell all the volume you manufacture you will have to lower the capacity of the fab and that translates in longer depreciation times etc etc.

14nm is a new process that needs at least 24 months in fuill production to depreciate its R&D cost, 28nm is a half node of 32nm that has already been depreciated and also has higher yields today than Intels 14nm.

Mask price is not the problem for AMD, it is the lower volumes they sell. They need to have larger dies in order to move higher Wafer volume. When they will manage to move higher volume they will start to make more than one die.

But Cat family does exactly this, they are half the die size of big core APUs.

Yes,

Intels 14nm is way more expensive today than GloFos 28nm.

And has surely a third of the yields at best...

14nm is a new process that needs at least 24 months in full production to depreciate its R&D cost, 28nm is a half node of 32nm that has already been depreciated and also has higher yields today than Intels 14nm.

Actualy even Intel s 22nm is substancialy more expensive than GF s 28nm.

AMD s Kaveri/Carrizo 245mm2 area is not a problem, all thevsubjacent economics point to a 2 modules + 512 SPs APU being more efficient economicaly wise that any other combination of modules and SPs.

Your conclusions do not follow from the statements you've quoted. Again, it's an equalizer. OEMs would be making similar margins on comparable ARM devices, except they'd be stuck with Windows RT.
They pay design, chip and equilize to stuff that is even worse...

Contra revenue is bribery we all know it.

A laptop, entirely different market as well. And no contrarevenue to compete against.
Intel bribes OEMs and OEMs make notebooks so guess why there are more crappy Intel notebooks on the market instead of AMD's actually better solution. You really want to advocate that i3 ULV and celeron and pentium is better than Kaveri ULV and Beema.
The only thing they have going for them is slightly higher single threaded performance. They have worse multithreaded perf and 1/5th of the graphics perf (which isn't even usable in many applications due to how buggy it is)

We ll see how it turns when Carrizo is released, this one has the core M as weak opponent and this latter can hardly be contra revenued...
This is a good point core M chips have underperformed so we can assume 14nm is nothing spectacular just Intel's way of fooling their investors. Efficiency is down and the gpu performance on core M is worse than it was before.

Do you think that Globalfoundries can manufacture a chip twice the size of Intel 2C processors and have a profit for less than Intel manufactures its 2C chips?
Considering how they work together with major players in the industry rather than do it all by themselves I think they could.

Intel even admitted that 14nm had problems and that the ramp up was slower than ever. (their slides played this as that every node has problems in the beginning as if anybody falls for that.)

AMD stays with 28nm this round because it will be cheaper yet as good as early 20nm nodes according to them. I expect depleted SOI.

On the lower tier, that is Mullins/Beema, AMD has better single thread performance but curiously we dont hear no more the single thread argument in this case, it seems it vanished , replaced by whatever other contra metrics...

I have a Beema notebook but the singlethreaded performance is worse that i3's it would walk over Baytrail and probably even celeron and pentium though.

It can't be a big difference. Actually it is quite sad I got a Kaveri notebook a few days ago and the singlethreaded performance was about on par with that of Beema...

You should report this to AMD and then authorities then. Because if it was true action would be taken. So I look forward to your documentation. Else I think we can easily rule out that "AMD is the better product".

What if it helps by reducing latency?

Maybe but the L2 latency isn't terribly bad. Not to mention that stuff that doesn't fit in L2 needs a trip to main memory.

This is a good point core M chips have underperformed so we can assume 14nm is nothing spectacular just Intel's way of fooling their investors. Efficiency is down and the gpu performance on core M is worse than it was before.

1. If AMD had a better solution it would be used, surely by smaller OEMs or by Apple, who would jump away as soon as possible (who considered it with llano).

2. Most users will not be using 4 threads in a celeron or Beema notebook. Singlethread performance is key.

3. Its nowhere near 5x, maybe 2x but not 5x.

http://www.notebookcheck.net/Intel-HD-Graphics-Haswell.93341.0.html

http://www.notebookcheck.net/AMD-Radeon-R4-Beema.115399.0.html

HD Haswell - 355 FS graphics
Beema - 492 FS graphics

Intel's drivers suck but neither GPU is really capable of anything more than browser or old games.

4. The GPU in core m is really performing well. Lets not forget that graphics performance is primarily power limited and HD 5300 is matching HD 4400 to within 10% at 4-6W vs. 15W.

http://www.notebookcheck.net/HP-Envy-x2-j001ng-Convertible-Review.130223.0.html

40 fps TR low, matches HD 4400

Intel seriously played up Core M. However, performance is really good for what you are getting. 14nm is roughly twice as efficient as 22nm but the TDP is only about 30-40% and so performance is a little less than regular U series. I never was taken in by intel's marketing (just like maxwell is not 100% more efficient) so i'm not really disappointed.

Carrizio may be a nice update but it has tall orders to fill. Beema pretty much abolishes low end Kaveri (same CPU perf, worse GPU perf, much lower power and smaller die). HBM won't magically raise GPU performance as the low end is mainly power limited not BW limited and more BW means better utilization and higher power draw as well as higher performance.

Mullins/Beema are the Baytrails contenders, theses are put against i3 because Intel s offering in this segment is too weak but they are not in the same prices brackets in principle, i3/i5 competitor is supposed to be Kaveri starting at 19W and mainly in the 35W segment, Carrizo will extend this range down to 12W, in low power i3/i5 territory.

Contra revenue is not bribery well OK you're entitled to your own opinion. Intel was sued in the past for bribing OEMs and anti competitive practices they paid a 1,5 bilion dollar fine. A fraction for the dominance they gained from these briberies because with AMD cash bound they gained over a decade of almost full market dominance.
Intel made almost 100x what the settlement cost was.

Crime pays at least it did for Intel.

Mullins is better than Baytrail obviously...

Yes singlethreaded performance is key celeron ain't much better than Beema.
http://www.notebookcheck.net/Intel-Celeron-2955U-Notebook-Processor.98845.0.html
Actually Beema does 0.6 in CB 11.5 and Celeron does 0.61. Beema is better in graphics and multithreaded performance there is no denying that. performance per clock however is a different story. But considering tdp of those solutions is equal or in favour of Beema we know which is better.

Also are you kidding yourself with that Notebookcheck review their low in games is 800*600. Core M sucks Intel over promised and under delivered. 4,5W no really not pure lies. I was in the market for core M until I read the reviews. It is consuming more than the competition and performs less.
Actually to prove their bias I'm going to compare the bench layout with a different review:
http://www.notebookcheck.net/Lenovo-IdeaPad-Z50-75-Notebook-Review-Update.127031.0.html


http://www.ultrabookreview.com/5486-lenovo-yoga-3-pro-review/
http://www.ultrabookreview.com/5648-asus-transformer-book-t300fa-review/

Notebookcheck is certianly biased read their conclusion it says "solid results" if those are solid results then why did they bash AMD products for their low performance while those had better battery life and way way better performance. Even better power consumption under load. BIASED!
I can't wait for someone here to say this is lighter than those notebooks well think again because this thing has a mass of 1,8 kg does 200g make the difference?

"The Envy x2 is to be in no way inferior to a conventional laptop"
if you mean by conventional laptop the worst we could find then indeed it is no worse.

They gave a 89% for a 33Wh battery. That is 3 weak cells bolted together how is that worth that high a rating :thumbsdown:

They gave 66% for games performance while it can really play not even play a single game in the test at a normal resolution. The Kaveri notebook I posted which has much higher frames and can actually play most games at reduced settings gets a 68%.
Do you think 2% for over 2x the performance is fair? It is a rhetorical question if your answer is yes then you are biased yourself.

In that same review they have load numbers that never actually occur I stressed my laptop and it is a FX-7500 with a R7 M255 (320SPs) for dual graphics and it doesn't surpass 25W on battery power. But hey let notebookcheck people be biased that is what they get paid for afterall.

Oh and if you think doing good compared to a previous Intel gpu is the same as doing good then you couldn't be more wrong. AMD and Nvidia are stomping Intel in efficiency and performance and driver quality. That won't change any time soon even Intel's 128MB L4 cache couldn't solve it primarily because it was too small to do anything at higher resolutions.

19W parts are heavily bottlenecked by DDR3 so HBM would be a huge help but unless you believe in miracles I don't think we will see it.

This forum needs a spoiler option because we are clogging up a thread that should be about Carrizo and it's advances.
