And not Kal-El, I'm talking about a low-power core that uses almost no power. The CPU would then be able to dynamically turn off and on the "main" cores as needed.

I bought some NVDA in April for my IRA. Not that a short term gain like this matters for my IRA, but innovation like this is good in the long run.

[citation][nom]amdwilliam1985[/nom]lol, time to buy their stock?[/citation]


Still a good time to buy. Techs have been down in the last couple of weeks. AMD certainly took a dive today which could also be a good time to buy as well (since they are down). Another reason to buy is that the general public has not caught on to android tablets yet thinking that the IPAD is the only good tablet out there. Personally, I have both the IPAD 2 and the Acer tablet with the tegra 2 processor. Needless to say, I like the Android tablet better.

Anyhow, hopefully Kal-El will help android sink into the tablet market and really help Nvidias stock price.
 
Sounds good on paper but then so does Bulldozer. Of course on both Kal-El and Bulldozer we really won't know until they are out. I'm going to have to miss out on the NVDA stock because I'm not all that confident they will get that kind of market share. Sure wont be mad if I'm wrong but I'm highly skeptical.

I don't foresee this happening with multiple x86 cores, since bringing it down to one wouldn't give that huge of a boost. Don't they do something similar with clock stepping?

Instead, this could be a progression of Windows 8's support for ARM processors. Use an arm core to run low-end kernel-level services, and wake up the CPU when you run applications that either demand the horsepower or an incompatible with the ARM architecture.

This is a highly competitive market, more so than NV had in the early days of 3D. Not a cakewalk for Nvidia, be skeptical on massive marketshare.

[citation][nom]rohitbaran[/nom]The benchmarks for this on some tablet were out a few days ago and it is left behind by Samsung Galaxy S2. Here is the linkhttp://news.softpedia.com/news/Nvi [...] 2908.shtmlIf nVidia wants it to be its money maker, they will have to do better.[/citation]
ok

[citation][nom]jblack[/nom]Why can't we get this on laptops?[/citation]
You actually already do. AFAIK, Windows 7 tries to only wake up more than one CPU core when absolutely necessary; and, at the same time, Nehalem-based CPUs (and more recent ones) completely shut down unused cores and cache.

If the CPU is basically doing nothing, on these laptops, the only power needed is to support the massive amount of transistors being kept on low-power states (it's a HUGE chip, after all, ARM chips are tiny compared to x86 CPUs).

Now, that being said, it would be rather interesting to see something like a companion Z6xx Atom core (or something similar, since it would probably need to share some logic with the rest of the CPU) on a regular SNB CPU. Those things are like 1W tops, if the rest of the CPU could be mostly shut down the power savings could be sweet. SNB ramps up rather quickly, another core could enable a smoother power ramp.

Cheers.

[citation][nom]lostmyclan[/nom]less watts low performance... more watts less batery life...can you run 15km with one liter of gasoline on a v8 engine?[/citation]
load the engine on a dolly and have a prius tow it there you go.

Well the problem with most modern day devices isn't so much about hardware, but rather the software smart enough to know when to underclock and overclock automatically when needed. Also programs which run on these devices don't optimize the use of the hardware.
I had read somewhere that android don't make efficient use of the RAM and just offloads everything on it. If its optimized, android phones could get way faster than they already are.

Ironically, Kal-el's graphics performance is old hat. The softpedia link is focusing on graphics. Kel-el is focused on raw compute performance. nVidia will be updating their mobile graphics with their more recent gpu architecture during the next generation.

The idea is ancient! The first time people started talking about a dual core system, two separate cores on a motherboard, later to be replaced by a single processor hosting 2 cores, the idea was mentioned to have a large and a smaller core. The smaller core running windows and it's sub systems, the larger core for applications demanding more.
However that idea was dismissed because it seemed too hard to implement, and to make both cores operate together would cause problems (because of one of the cores finishing a thread faster than the other).

I really don't understand why Nvidia needed a fifth core to get to these results. It would actually be better for them if they had a dedicated core on the quad core chip doing that job. The fifth core would only add to costprice, and draw power in standby.

Marvel did this with a triple core smartphone chip. 2 highend cores and 1 lowend: http://blog.gsmarena.com/triple-core-1-5ghz-marvel-cpu-amazes-the-smartphone-world/

An extra core is all nice but with every addition comes higher prices.
