Is that confirmed, if yes then is there a possibility that there maybe cheaper variants of Surface PRO ? I'd like to wait & watch because with win8 sales tanking MS will need to push these tablets more than ever also under a certain price point, say 500~600$ roughly, Intel parts will not be profitable for OEM's & even if they chose to go with Intel then we'll see the same atom fiasco all over again !

Digitimes had a list of suppliers for the components. It was Intel and nVidia.

And we heard all that nonsense about cost over and over again....

You cant just multithread everything, thats the point.

No, obviously not, but you can do a fairly decent job of it. *shrug* Amdahl's Law obviously always applies, but the question is how small you can get that single threaded portion. I'm writing this on a 24 thread workstation- moar cores certainly has it's place.

We'll just have to wait and see. I expect the first generation of games to suffer, certainly, but hopefully within a year or two they'll be doing better.

Cost is the one/main thing that sells around a billion(guesstimate) or so ARM chips & you just can't pretend it doesn't matter because surface Pro was indeed a major flop in part due to ~ make a wild guess btw it starts with a p & ends with an e !

It actually starts with W and ends with an 8.

CPU and GPU both running off of a single channel memory? No wonder Sony chose GDDR5 to go with it.

It's only single channel in the Kabini SoC. PS4 and Xbox 1 both have 256 bit memory.

No wonder the other Temash review said games was CPU bound at a slideshow rate. Specially considering the TDP at that slideshow rate.
[...]
I shiever by thinking of 8 of these cores in consoles. But again, new consoles is about TV, TV, TV and TV
Temash has 1x64b DDR3@1066 MHz IIRC. A GPU displaying game graphics needs a lot of mem bandwidth. In Temash's case, this is already low, stealing b/w from the CPU cores.

The consoles don't have 8 starving and throttling Temash cores. Given, the slideshow rate is caused by bottlenecking CPU performance, we might look at the console CPU cores: Both consoles provide more than 20x the mem bandwidth (incl. ESRAM in XBox One) and roughly 4 times the raw parallel CPU compute power (2x clock and 2x cores). Then there are savings in more efficient OS functions and game/graphics APIs etc. This doesn't look like a problem anymore.

How much performance do the Temash/Kabini Jaguar cores lose by having only one mem channel?

While I didn't care for Windows 8 on my desctop and moved back to W7, I have a W8 tablet - HP Elitepad 900 - and it is by far my favorite tablet taking both Android and Apple into consideration.

On even an Atom powered tablet I understand where Microsoft was going with W8. Just my opinion however.

Don't get me wrong, Kabini is a nice product, but it will be hard pressed in Q4 by silvermont and Haswell. Silvermont is likely to be cheaper, and Haswell will offer better performance. This is a competitive picture far more complex than Brazos when it arrived.

That's why they neeeded to launch it NOW.

You know what's most interesting to me, is that this, like their Bobcat stuff is not produced in GF. Both of these have had decent niches and seem to be at least reasonably competitive. This has me wondering how much of AMD desktop woes are due to AMD and how much are due to the foundry they're stuck with.

Well Starcraft II would agree with you, but I think the point is that they can be threaded better than they currently are.

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.

I just dont understand the lack of SSD controller on the SoC. No one wants to deal with a slow-as-molasses 5400rpm hard drive. And OEMs will never accept the $50 increase in BOM. So you put the NAND controller on the die and make the OEMs fork over exactly the same amount of dollars in NAND as they would on a hard drive. Then they'll use the NAND. Through clever tricks you can make a 2 channel on-die SSD controller run just as fast as a 12 channel SSD controller through a PCH and a SATA interface. It is a complete mystery why they still havent done it.... they are jsut impaling a dead horse at this point. The computing experience you get from a HDD is simply unacceptable today. Most people would prefer android vs windows with HDD, it is just too frustrating, not to mention needlessly more expensive.

I've heard that NAND controllers are actually very complicated - apparently the raw bit error rate on flash is very high, and it takes a lot of work to build a decent (fast and reliable) controller, so I wouldn't expect to see an integrated one any time soon. Maybe Intel could do it, but I doubt AMD could.

No, obviously not, but you can do a fairly decent job of it. *shrug* Amdahl's Law obviously always applies, but the question is how small you can get that single threaded portion. I'm writing this on a 24 thread workstation- moar cores certainly has it's place.

We'll just have to wait and see. I expect the first generation of games to suffer, certainly, but hopefully within a year or two they'll be doing better.

The interesting thing to me is that games were basically the last "heavy" workload that isn't embarrassingly parallel, and for a long time people said they would stay like that. You can already do a lot of other tasks on a tablet, and if AAA games have to support 8 slower cores, it seems like players who couldn't historically deliver Intel-level single-thread performance (ARM/Qualcomm/Marvell/Apple/etc) could enter more markets.

See this ~

Of the top three or four OS available for a tablet, or tablet/hybrid PC, win8 is easily the best & its certainly not in the top 3 reasons why the surface RT/Pro flopped big time, well at least as far as I'm concerned !

I noticed that every site compares the kabini and temash to i3s, I wonder if this is an AMD mandated move or they just think that this competes with i3 rather than pentium and celeron?

AMD positions its 25W model against the lower end of the i3 i believe.

All the other models are vs celeron/pentium

I believe AMD handed them a $500 laptop and told them to compare similarly priced parts. A bit silly considering the laptop had a high quality 1080p display.

yeah, I saw the slides of it being under 13 but every site I visit with a "review" has it competing with an i3 of some sort...hell pcper had it competing against a desktop class i3

I think these guys kinda get it...maybe http://www.techspot.com/review/671-amd-a4-5000-kabini/page6.html


they are comparing 65+w desktop parts to a 15W mobile soc...theyre also testing ivb celerons and pentiums, the right matchup for the apus...


it's hard to find what exactly to compare to... Bobcat sure, Atom yes... ULV, why not? other cheap CPUs sure... I don't see any problem... a direct comparison with ARM CPUs is hard to make.

just because Kabini is cheap, it's going to be sold on all sorts of devices (desktops, low end 15" laptos, whatever)... like Bobcat was.
