Llano TDP can match Intel's quad TDP

Written by Fuad Abazovic
fusion

35W to 45W
We have been playing with some quad-core Core i7 notebooks, some of them clocked at 2.2, GHz and found out that Asus' N53SV 15.6-inch notebook can give you some three to four hours of endurance. Since we got a hint that Llano TDP has 35W to 45W depending on the clock and configuration, we have decided to compare what Intel has to offer in that TDP range.

Core i7 2720QM that we have tested works at 2.2GHz native clock but with turbo it rocks to 3.3GHz has 650MHz graphics and 1300MHz graphics memory. This is a 45W TDP CPU. A bit faster one is Core i7 2820M, again a quad-core with eight threads with 2.3GHz core clock and 3.4GHz clock with turbo. The TDP remains the same, 45W. Intel has bunch of 35W dual-cores and the fastest one is Core i7 2620M that supports four threads hyperthreading 2.7GHz core clock and 3.4GHz turbo clock.

These are the top parts in 45W TDP range, and these 45W quad cores will go after highest clocked and best performing quad core Llano. Still, even being a year too late, we expect to see Llano lose to Core i7 2x20QM in CPU performance. On the other hand, we expect it to win in the graphics part of benchmarks hands down.

In the 35W dual-core market, the competition is tougher but its safe to say that Llano in 32nm can definitely come up with better graphics, but we are not sure if its dual core can win against 32nm based Sandy Bridge.

I believe you are right, however you forgot to mention an important factor: pricing. As a rule, AMD offerings are always significantly cheaper than Intels, so even if they CPU performance might be trailing behind, depending on the price Llano could offer exeptional value.

What insightful journalism, Fudo. Charlie should be worried.

Fuad and Charlie should be posting on one website, too much side comments which is unnecessary unless this is editorial article.

you forgot that AMD will have a far better GPU in the apu than Intel has

Come on AMD, it's about time we all need to see the goodies. :sigh:

Yup I think for general usage these will probably be better than intel. Most of what I do is gaming and multimedia both of which utilize gpu more than cpu.

It seems to me a 35W llano will displace zacate. Being on 32nm I bet the idle power consumption will be better, so unless zacate is moved to 32nm its toast.

Win? Win in what? Graphics power? Graphics quality? Battery longlivety? GPU compute? ;) Surely you know, it all depends on what you want to do with the chip...
