Intel Clear Video technology

[goyalonkar40]

Hi

I have to buy a laptop which I need to watch HD movies, surf internet, watch online videos (all these things simultaneously). What configuration will be sufficient for that?

 

Will Pentium 3825U or N3540 (without any discrete graphics card) be sufficient or should i spend extra money for 4005u? 

 

 3825U has Intel Clear Video Technology  but doesnt have Intel Clear HD Video Technology, while N3540 has neither. And 4005u has both. Does it mean that 3825u and n3540 will give inferior video quality compared to 4005u?

 

Celeron 3050 has intel clear hd video technology, does it mean that it will give better video quality than 3825u?

 

Which is better out of 4005u, 3825u, n3540, n3050? Pls arrange them in ascending order.

 

Which is better out of 4005u and 3825u? cpubenchmarks site gives more points to 3825u. Is it really better than 4005u? If yes, then why 4005u costs $90 more than 3825u?

 

Can all these processors (without any discrete graphics card) play 720p and 1080p videos smoothly?

 

And whats the difference between intel clear video tech and intel clear hd video tech?

 

 

 

Thanks
