Lenovo or Asus? Which one is the better 'Performer'?

[falcon54]

hey guys, I am out to buy a mid range laptop and I'm a hell lot confused regarding these three laptops :

1. http/www.flipkart.com/asus-x550lc-xx039d-laptop-4th-gen-ci5-4gb-750gb-dos-2gb-graph/p/itmdrjhyegcmrb9b?pid=COMDRJHXTE4MVTJJ&srno=b_6&ref=ba6d408c-44ad-4b5d-85e7-3fd9e23f46e5

2. http/www.flipkart.com/lenovo-essential-g510-59-382843-laptop-4th-gen-ci5-4gb-500gb-dos-2gb-graph/p/itmds7zxg2ugvgat?pid=COMDS7WYHHVPJQSZ&srno=b_4&ref=89172698-ae58-4632-9102-d0ca4ce1e3ff

3. http/www.flipkart.com/lenovo-essential-g505s-59-380146-laptop-apu-quad-core-a10-8gb-1tb-dos-2-5gb-graph/p/itmdm79dbkjzewwk?pid=COMDM799ZGJTXAVT&srno=b_1&ref=a19606a3-2593-4a69-b3b6-3c36bb6d9983

Also I want to know that is Lenovo or Asus better, performance wise, keeping in mind factors such as battery backup and heating?

And what is the difference between (and which one is better?)
1. Intel Core-i5(4th gen) 4200U
2. Intel Core-i5(4th gen) 4200M

and also should I consider going for AMD quad Core A10 5750M over Intel Core-i5(4th gen).

Any help would be appreciated.
Thank you

The 720m, while being a low powered card, has slightly more power than the 8570M, but theoretically the A10+8570M is better, but due to unstable(variable) frame rates in practice should be about the same. The 4200M would be the fastest, followed by the 4200U and the A10 for processing speed. the biggest difference between the 4200m and 4200u is the pwer draw and heat output. The 4200m is also a socketed processor(not all very important.).

okay, so I think I'll go for 4200M. But, since it's power draw and heat output is more than 4200U, so does that imply that the laptop with 4200M will give a low battery backup and get more heated up than the laptop with 4200U?

It all depends on the chassis, battery life really shouldn't be too much different with the same battery between them, the one with the bigger battery would normally win. The 4200U will most likely consume less power under light load, but the Lenovo will have a bigger battery(it looks like Asus has 2/3 the cells without knowing capacity) Keep in mind the difference in graphics power as well http/www.notebookcheck.net/Mobile-Graphics-Cards-Benchmark-List.844.0.html

Okay, I'll definitely keep in mind the graphics power. Thanks mate, for the info.
