Isnt the i7 supposed to be faster than the i5?

I am getting ready to purchase a new laptop and am trying to decide between 2 different models of Acer Aspire v3 771g
(1)
Intel Core i7 2670QM(2.20GHz) with a GeForce GT 640M

(2)
Intel Core i5 2450M(2.50GHz) with a GeForce GT 630M

I was pretty sure I was going to go with the first one since it has a better card more memory and has an i7 but its speed is only 2.20 while the i5 has a 2.50. Does that not mean that the i5 would actually be better? It is 120$ less.

  1. Best answer
    That depends on what you are going to do in the laptop, i7 is faster in highly threaded applications, i5 is better for gaming (in some cases i7 can be slightly slower in gaming).
  2. Its pretty much strictly for gaming and typing up my notes. Mainly skyrim and LoL. I was hoping that the i7 would have still been better for that since it had more HD space and memory.
  3. Well you can still use the i7 for gaming although there won't be a very noticable difference between the two, the extra RAM, better GPU and bigger HDD covers the cost of $120 as they will help with gaming (particularly the RAM and GPU).

  5. Thanks for the answer. I think im going to go with the i7 because of the GPU.
  6. The i7 is a quad core while the i5 is a dual core. Also taking a look at the turbo levels may be helpful.

    i7:
    1 core - 3.1
    2 cores - 3.0
    3 cores - 2.9
    4 cores - 2.8

    i5:
    1 core - 3.1
    2 cores - 2.8

    So the i7 would be faster in single and multithreaded apps as long as thermal and power limits are well enough for turbo to engage. But as said the gpu is more important for games.
