Hmm..Atom and AMD are x86 and as such do not compete directly with Tegra. The performance ceiling is owned by x86, however power is the issue and becoming less of one every 6 months or so. When an x86 tablet that out performs ARMH risc at similar energy footprints becomes available then that will change the market. As Windows legacy products will become available. The world is designed and runs on x86. Apps run on ARM risc. Big difference. I think that the importance of Jaquar though will not be in mobile devices but in the SeaMicro server products. I find it amusingly ironic that AMD is now an oem who can profit from both ARM and Intel. SeaMicro was a hedge investment!

I suspect cores need to run at the same data rate to access the shared L2 cache. They can go to sleep states independently, though.

I'll be very interested to see Temash, that sub 5W AMD chip with Jaguar next year, but I suspect there will be Atoms and Tegras that leapfrog it quickly

I dont have hope that tablet segment will be captured by x86. ARM chips are getting more and more powerful, and they have all the processing power they need.

"One down side to the approach is that all four cores must run at the same dynamic data rate. That means the unit may burn excess power if one tasks needs a high frequency and other simultaneous jobs do not. " ---- have no idea why the other cores need to work at the same speed? in multi-task jobs state, quad core can be in symmetry or asymmetry mode... so let us wait for the detailed spec for it.

With this AMD Jaguar, they sure can compete with Intel and Nvidia in the mobile market.

The one thing I expected to see was the power numbers for the chip, especially as it is touted as a mobile core design. I like the idea of the shared L2 memory and wondered if the design allows for one to three cores to deep sleep if they are not needed (thus saving power)? While the cores all must run off the same clock, I wonder if they put in any clock divide logic to all for half or quarter speed operation off the same clock. Time and spec sheets will tell..

The cores can run independent tasks but they must all run at the same clock rate. Since there is no working silicon yet, AMD has no hard numbers on performance, power, etc.

"One down side to the approach is that all four cores must run at the same dynamic data rate."... Does that mean the cores can not perform independent tasks? Or does that mean that all the cores run with a common clock? How does the power consumption of AMD Jaguar compares to the competitors' product such as Intel's Atom etc.?
