Intel or AMD CPU is better for overclocking?
 
Intel or AMD CPU is better for overclocking?
Any recommendation?
My target is to hit 5GHz. :D

I think I want a CPU with at least 4 cores.
And 8GB DDR III RAM.
Sata III HDD 1TB or 2TB.

My recommendation is to not have silly and extreme overclocks as a goal. 4.5-4.6GHz is about as far as anyone goes with i7s and bulldozers.

Even 4.5-4.6GHz isnt something you do without some very good cooling, and quite a bit of experience and knowledge. Trying it without those will probably just result in 'letting the magic smoke out' of your new CPU..

Why AMD 8 core CPU does not out-perform Intel 4 core CPU?

I'm fairly sure you've asked that before, and didnt like or understand the answers.

Check the prices. Current prices (2012-10-20) from newegg.

i5-2600K- $220
i7-2600K- $335
i7-990X- gone, but IIRC last time I saw one at newegg it was $600+. Release price was $1000+.

AMD FX-8150- $190

For the price, the FX isnt that bad, and can generally keep up (and sometimes be faster) than the more expensive i5-2600K.

BTW, the test you have linked to is early in the FX release cycle, they have improved the drivers etc. since then. It also very heavy on artifical tests where intel is generally better than AMD. Real world tests are more accurate.

Do you mean the benchmark is biased?

One question,
will future games going to use more cores than now, so investment in 8 cores CPU is a wise decision?

For the most part, you get exactly your monies worth on a cpu. They are very carefully marketed to the true power. The high end and low ends are exceptions as one may be a value while the other may simply be the greatest.

It may be generally easier to overclock AMD if you add up all of them.


The motherboard and associated parts also play a very big part in the calculation.

The core i7 is the best for desktop and maybe the xeon is best for server while AMD fills in a builders market.

I can understand the desire for faster and faster. That said, if you were the person who should try designing it, you probably wouldn't need to ask the question :-P.

I'm not the person either, but I have designed electronics. When you strip the imagination and marketing from manufacturer's specs you find you are dependent on much they have done, and much they don't wish to highlight. When you look inside a pc, buses are slower, graphics is slower, software is more bloated,

The way to approach it is to find the best - not necessarily the fastest. That requires days of comparing specifications. Don't pick a figure out of the air, but find what some setup is reliable at. I feel sure this 5GHZ box won't be built - yet. And pcie only goes so fast, SSDs ditto, pci is slower, ram itself is slow enough(6-1-1-1). So the difference between 3ghz (Very doable) and 5ghz isn't that great unless you're running some loop purely out of cache. If you're working on it, you're just idling faster.

Seeing you asking this question and your unrealistic goal it is clear that you simply lack the knowledge for a successful overclock, let alone in the targeted range.
You will at least need a high quality mainboard meant for overclocking (price-range 150$+), a decent cooling system (air cooling will not be sufficient for an overclock in that range) and, most important, a deep understanding of how the hardware works and how the different components work together.
Not having this knowledge will most likely end with an unstable (and therefore useless) overclock or, worse, you buying new hardware because you fried your machine.

I will refer to some websites that teach you how to overclock.
They recommend mobo and cpu.
And the settings too.

Even Intel teaches you how to overclock:

5GHZ is not an easy target. That is, if you plan to actually use the processor.

I run a core i7 2600k with a water cooler. The original heat sink was horrible. At idle, it runs just above room temp at idle. Huge improvement.
I spent a long time overclocking slowly so that it didn't exceed the design temp (72C) at room
temp. I didn't get very far despite the water cooling. You should really try to keep your system stable, and unless you plan on playing video games for 10 minutes at a time, you have to.

if you really want to overclock you are going to need a good motherboard as well as some crazy heat transfer. you should probably look in to a phase changing cooling system. Not cheap for the initial cost or your electric bill.

good luck

Other than stepping up the multiplier figure, the voltage needs to be increased too.
I will search for people's testimony of over-clocking and follow the successful parameters.

Of course, I need water cooling system, not only Fan.
