hey guys i have few questions about CPUs

1.According to this site (http://techreport.com/review/23246/inside-the-second-ga...) . cpus from i5 3470 to top i7 cpus have unnoticeable difference when it comes to gaming . why ?

2.This might be same as first question . but why gaming performance does'nt differ much from cpu to cpu but it does from VGA to VGA . yeah vga is doing the main rendering but by the help of CPU .

3.Why i5 3470 performs better than i7 in some gaming benchmarks ? i7 has HT & it should perform better. so whats the deal ?

4.i currently own i5 3470 . will upgrade to higher Model affect my gaming performance ? ( im gaming at 1360x768 res )

This is going to be a very "informative" thread. I can see it now...

as to your last question, you could buy a super computer processor, you wont see a benefit on any game at that resolution.

the cpu says do this, because that's what the program tells the cpu to "do" the gpu actually does it. gpu has ram processor chipset all on its self, so its like buying a whole computer that's dedicated to grapics. which is why they vary so greatly, most game literally use the cpu in totally different ways causing some to benefit from different cpu's. so like batman can be faster on a certain i5 and slower on an i7 and battlefield may be the reverse.

EDIT: But there is a bottleneck the game itself creates by resolution and detail that makes anything above that i5 as you mentioned not make a huge difference, up the resolution and detail and amount of AI and running components in the game and there will be a noticeable difference... as long as you get a beefier GPU to allow the processor to pass that bottleneck created by the games settings.

Most games don't use but 4 cores and most i7 CPU's have 4 physical cores and 4 virtual cores. its a cool technology but mostly that's why i7 isn't needed. it isn't worth having a super CPU if your just going to be playing games. If your doing video rendering and stuff of the sort then that's when i7 comes in handy :)  oh and your res is very low and the processor you have is fine for what your using it for :)

(1). Games for the most part are not multi-threaded workloads and dont take advantage of having more cores/threads. An i3 isnt the best for gaming due to its low clock speed and poor single core performance. An i5 is the best for gaming because it has extremely good price to performance ratio, clock speed, and single core performance. The ONLY reason someone needs an i7 is for extremely multi-threaded workloads or rendering and 3d art.

(2)Graphics cards effect gaming performance. Each graphics card has its own processing units, VRAM, and cores and such. Graphics cards render out an environment and game. When you launch a game, the graphics card somewhat takes over. Buying a cheaper cpu and spending the extra money on a graphics card is worth it when you are playing a game.

(3)Synthetic Benchmarks are never what you should look at. Look at real world benchmarks like games and such. The i5 and i7 are the same in games and in those benchmarks they dont utilize the full power of hyperthreading.

(4). You dont need to upgrade your cpu for that resolution. That cpu should not bottleneck any graphics card at that resolution. Spend the money on a graphics card.

Ans 1. There is no difference in gaming because the current top games all do not use only 4 cores at the most. So it won't make a difference.
Ans 2. When you game the graphic card is more important simply because games need more graphic rendering than anything else. (Maybe 4k video editing may demand more from gf card than games).
Ans 3. If what you said about i7 having ht was true then all the fx series processors at stock clocks would simply destroy all i5's. However none of the current-gen games really use HT. It comes into use in multitasking,video editing, 3D rendering. Anyways when the cores are not being used while gaming, the number of cores doesn't make a difference.
Ans 4. It will not. After 3 years maybe it will. You will get only +5 fps which is not justifiable considering the cost of an i7.

Also instead of looking at an i7 consider upgrading your monitor and start gaming on fullhd with clarity. YOur i5 will not bottleneck any gf card currently.
