That chart is only 2½ year old
And why is that irrelevant today ? The performance that you could get in a 600$ phone a couple of years back can be had for 200$, or even less from some Chinese vendors, granted the SoC performance gains are phenomenal in the mobile arena but the point still stands truthfully even in the PC industry.

For instance how people complain that Nvidia is price gouging even though inflation adjusted prices for flagship GPU's has been nearly constant over the last decade or so, in other words they're getting 2~5 times the performance of previous flagship GPU's at constant price after adjusting for inflation. Hence this argument that the low end netbook market being irrelevant is rather moot.

The obvious killer for such devices is the tablet of course but as Abwx said that within the notebook market the overall share of low power/cost is gonna increase, how much though is not a prediction I'd like to make !

And trends change. In the same timeline that chart is made. Intel for example had a 23% revenue increase. And Samsung only grew 3%.

Your chart is useless today, and the trends didnt hold.

And looking back on AMDs product mix, their mobile bobcat shipments are dropping fast. But again, so is everything they make.

Can you point us numbers that show that intel
growth is due to their top segment CPUs offerings
rather than lets say SSDs..?.

Your chart is useless today, and the trends didnt hold.

The only thing that is useless is your biaised analysis
motivated by the need to downplay AMD as proved
by the last part of your post :

And looking back on AMDs product mix, their mobile bobcat shipments are dropping fast. But again, so is everything they make.

Always the same story , unabated , in your posts ,
you could well edit a definitive one that could be used
whatever the subject...

A very interesting claim in TR s review.

The key words above, by the way, are "small-scale." AMD tells us these chips are being manufactured by two different foundry partners, TSMC and GlobalFoundries, at 28-nm process geometries.

Although they share quite a bit of DNA, Kabini and Temash are aimed at much lower cost and power targets than the chips AMD has built for Sony and Microsoft.
So Xbox and PS4 APUs are fabbed by GF at 28nm.

You don't actually believe this do you? I know from my personal experience I've had numerous people ask me for help buying a laptop, with the stipulation being that they don't want to spend more than $400. While I agree with some of the posters here that most (almost all) of these laptops are junk, that doesn't change the fact that this is what people are buying.

In total, sales of Windows notebooks dropped 11 percent from 2011's holiday season, with their average selling price rising just $2 to $420.
Or, as NPD's press release puts it, "Despite the hype, and hope, around the launch of Windows 8, the new operating system did little to boost holiday sales or improve the year-long Windows notebook sales decline."

Unless you are Apple, you are not selling many expensive laptops these days (at least to consumers). This came up from a quick Google search, not difficult to find.

You do know your own link perfectly proves that I am right? Shipments are not going up, they are going down. It is also quite obvious in AMDs product mix for Q1, Q2 and Q3 2012.

I thought you were one of the people who insisted PCs weren't dying?

I am referring to the mix of prices. I know PC shipments are falling. If that is all you meant I misunderstood your post, sorry. I thought you were saying that people are buying more expensive laptops.

Who says PCs are dying? Its just financially hard times for alot of the world. Even for iPads:

Not to mention regular shop deaths. People save up money instead of spending basically. As its also shown here in Denmark.

I thought the gaming results were interesting:



Not really relevant the x202e notebook they tested has horrible throttling problems (like 1.2 ghz core and 300-500 mhz igp under load). Difference in performance should really only be around 20% at most.

Toms review on the same or similar cpu (i3 ULV possibly different model--100 mhz difference)

TR used a laptop with single channel , THG used a dual channel.

The A4 is also on single channel.

Dont know for TSMC , for GF AMDs Trinity has about 5.3 millions transistors/mm2, going to 28nm should increase density by 30% to 6.9M/mm2.

As a comparison Intels IVB has 8.75M/mm2 density.

Awesome! Hopefully AMD can stop getting shafted by the WSA for a bit.

Some corrections to take with some salt ,
PS4 APU will be fabbed by TSMC since they use Jaguar cores
while MS Xbox APU will be fabbed at GloFo , hence only 768 SPs
but with Trinity cores.

I am pretty sure that the Xbox APU is also using jaguar cores, 8 trinity cores + 768SPs + 32MB ESRAM will make yields very horrible.

The Xbox One is jaguar cores, unfortunately.

Quite the contrary , it s a very good news technicaly speaking if this is the case as it would mean that they have no trouble porting a whole CPU through two different processes in a very short time.

Not really sure I understand this comment.

In any case, if they are in fact fabbed at different foundaries, it could be an interesting way to compare the two processes. Unfortunately the different OS systems and lack of cpu testing apps will make any direct cpu comparison very difficult.

I assumed they were both from TMSC. If in fact they do the xbox at GF, at least it will help them meet the WSA.

Porting a CPU layout from a foundry process to another one
is not , or rather wasnt , economicaly viable because you ll
had to redesign the complete circuit in function of the new
process transistors caracteristics but if they managed to do
so with Jaguar means that their computerized tools are very
advanced and work well so they ll need far less workforce
for implementing their future designs.

The use of an 8 core CPU and 8GB RAM in consoles forces developers hands to make well threaded games and use 64bit engines. Both of these should be considered good things for PC gaming and console gaming alike.

I think there's a pretty good argument to be had that the biggest limitation of console games is their current memory limitations, 500meg for CPU / 500meg for GPU on the PS3 has to be a pretty severe limitation that sucks up development time in just trying to figure out what all they need to cut down just to keep things from overflowing 500 megs. Regardless of the fact that consoles aren't and never will be huge powerhouses, the console generation turn should give a good shove in the right direction for PC gaming.

Agree. Only a minor correction. The PS3 has a total of 512 MB. 256 for RAM and 256 for VRAM.

Holy moly! I'm really curious to see the numbers for the 25W Kabini now.

The most important measurement must be idle. There is near a 3x reduction on consumption. Wow!

heh, anyone benched it against ATOM D2700 ??

That chip is already phased out (End of Life)

http://ark.intel.com/products/59683

But in older comparison with E-450, the AMD was better. Almost same CPU performance and very superior GPU performance: about 5x.

http://us.hardware.info/reviews/2700/20/cpu-shoot-out-intel-atom-d2700-vs-amd-e-450-conclusion

The official TDP number is accurate for the pentium , interestingly ,
but not for the ULV i3 , that s how they artificialy create a higher
performing product marketing wise , just use the same 35W CPU ,
claim half the TDP but let them run at 30W for a few minutes ,
it really helps when they are rewiewed.....

The funny part was when Intel believed its own marketing hype and put one of those i3 on the NUC

Kabini have a 25w model, considering it integrates more, it should be comparable to the 17w i3s/i5s in terms of power, BUT, performance is not that easy, it's a 500MHz increase, so it's going to look good in many MT tests, but ST still is a big factor for basic usage (web browsing..) I think... so focusing to much on MT benchmarks can be a little misleading

ST benchmarks are valid for legacy apps and if you avoid multitasking.

Multitasking is normal user behaviour those days. And even if you are only browsing the web, modern browsers use multithreading.


I thought the gaming results were interesting:

And Skyrim is one of that half dozen of Intel-optimized games.


And looking back on AMDs product mix, their mobile bobcat shipments are dropping fast. But again, so is everything they make.

LOL

Actually you have it backwards. It is only about half a dozen games at most that are competitive at least on amd vs Intel when using a discrete card.

Amd has the advantage in desktop igps, but for gaming that doesn't mean a rats butt to me. I would use a discrete card anyway.
