Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
Ars also gives the SunSpider results at 294/128 which is crushing while it gives a Octane scores of 9000/12000, which is a beating but not a crushing.
According to this review: http://www.ultrabookreview.com... the 3DMark values you are touting here fall apart on repeated running because of thermal throttling. Now, this is not necessarily the chips fault, maybe Lenovo did a bad job designing the cooling system, or is being too careful with overheating. An iPad Air 2 may throttle a bit, but not the 80% loss of CPU speed seen by the Yoga Pro 3.
Regardless, the hardware throttles aggressively and there’s little one could do about that. For instance, when trying to play games, both the CPU and the GPU drop to very low frequencies. In fact, I wasn’t able to run properly any of the titles I’ve tried on this laptop, not even older ones like Dirt3 on HD resolution with very low details. I did got somewhat better results when playing the game in Window mode, as you can see from the pictures below (look for Average CPU and GPU frequencies), but switching to Fullscreen resulted in an average of 6-8 fps. The same happend when trying Metro Last Light and I just gave up after that.
My point here is that at this rate, Apple will be putting out a fanless device that is faster, uses less power, has less thermal throttling (so wins both sprints and marathons). As of now, they have a device that uses less power and is faster at certain operations and will win most marathons.
GeekBench 3: Multicore
Yoga Pro 3: 3981
iPad Air 2:4553
GFBench 3: Offscreen (Manhattan):
Yoga Pro 3: 23 fps
iPad Air 2: 33
GFBench 3: Offscreen (T-Rex):
Yoga Pro 3: 45 fps
iPad Air 2: 70.4
Obviously, I'm cherry-picking here, but still. The iPad Air 2 weighs much less than the Yoga, and gets better battery life. It should not be able to trounce it at any significant benchmark.
