Hello,

I am new to the computer world, and I'm picking out my specs to build my own computer.

I have some questions about the CPUs

1. this processor:
http://stores.tomshardware.com/search_getprod.php?maste...
is a lot more expensive than
this processor:
http://stores.tomshardware.com/search_getprod.php?maste...

I know that the speed of the CPUs are calculated by GHz, then how come the i7 is much more expensive, when its actually slower?

2. I understand the single core, dual core, and quad core, but what is "pantium" "i3", "i5", and "i7"?
I know i3< i5< i7, and single core < dual core < quad core but could you explain in detail what does numbers mean and list them in order according to their performance?

3. What is a good "bang for the buck" CPU around $100?

4. So from question #1, obviously there is some other factor than just GHz to look for when buying a CPU. what is the other factors I should look for when buying a CPU?

Hello jineus;

Take a look at the THG article: Best Gaming CPUs For The Money

1. While X Ghz is about how fast a CPU runs - it's not about how powerful the CPU is when operating. Speed doesn't always equal power.
2. Brand and model names. See this link: http://ark.intel.com/
3. See the article above.
4. What will you use the computer for? What is your total budget?

Okay, so the speed is how fast it can run things. Then what is power? I know the concept of single, duo and quad cores, but I don't understand i3, i5, and i7.

The link you sent me is helpful for me to pick my out CPU, but the article assumes that I know basic information, which I don't. I still don't understand the new i3, i5 and i7 cores.

I have a budget around $600. I have a moniter, mouse, speaker, keyboard, windows vista, etc. So I can upgrade those accesories later. I could pick out my specs according to the ratings, and the suggestions from other people, but I want to understand the full concept first, choose my own specs, then get feedback.

i7>i5 7xx>i5 6xx>i3

i7: 4 cores + Turbo Boost + Hyper Threading
i5 7xx: 4 cores + Turbo Boost
i5 6xx: 2 cores + Turbo Boost + Hyper Threading
i3: 2 cores + Hyper Threading

I have another question:

"Intel® Core™2 Quad Processor Q9650
(12M Cache, 3.00 GHz, 1333 MHz FSB)"

what does "12M" "Cache" "1333MHz" and "FSB" mean?

well Thats not the problem, I'm just trying to understand what those mean. I just chose a random processor as an example.

Also, hyper threading seems like it enables the processor to do...multitasking, basically. but i5 has our cores. How can i5 use all 4 cores when it does not have hyper threading?

Learn how to use "Google" & "Wikipedia" and read all the materials patiently.

Speed is just that - how fast the engine runs. It's not the same things as how fast computer tasks can be finished.
Note the AMD Phenom II X4 965 (3.4Ghz) BE and Intel Core 2 Quad Q9550 (2.83Ghz). X4 965 might run faster but Q9550 is more powerful running the Sysmark Productivity benchmark test.


What level of detail do you need to make your decision?

If you want to learn get a book, or use Google. Its really not hard to figure out.
