Stock clock vs OC Question

[justin4pack]

So I wonder, why do cpus such as the SB gen and i7-9xxx Gen and so on, why are they sold at very low stock speeds when they have so much gain in OC without any side effects?

Wat is i7 9xxx gen ?

Your not making it clear, what do you want. What is your question.

Because 40 percent are enthusiast and 60 percent are normal people. Who don't know what OC means. thx gl

Most people believe that is because of the lack of competition from AMD. Plus, it makes it a lot easier to release a next-gen CPU at the same clock speed of the previous gen, with just IPC improvements.

Edit: Also, there are drawbacks to higher clock speeds. More power, higher temps, less longevity.

Higher oc numbers and you got allways room to have a bad chip next generation without showing it at it worsted.

See 2600k if they had sell it at 4ghz they had to provide a better cooling and not a 20mm one, second the oc would be max 0.5ghz for the majority with air coolers. And then the 3770 had to come out at 3.8-4.1 to get sold as a upgrade where would be his oc range for common users, on a decent temperatures? And finaly look the 4770 with his crappy thermal paste and think he would be at 3.8-4.1ghz hahahaha.

Don't forget that was for the k chip series that means they should have a decent OC range so they could sell k and non k chips.

And ofc as virtuallarry said no competition leaves them to sell a 5% better item as new with higher or equal prices and people are satisfied with it.

Lok at nvidias 760 770 old generation chip with new gimmicks but at least the sell it at lower price then last generation.

There is multiple side effects. Thinking otherwise is just silly.

Also there is different electric and thermal levels as well to bin for. The platform is 95W TDP for example.

Its like saying car manufactors ship cars with nerfed engines, because you can chip them and get more HP out of them. Obviously no competition in the car industry. D:

Intel hasn't been concerned with raw performance for some time. The focus is now on performance/watt. Haphazardly pushing clock speeds up isn't good for efficiency.

Take a Core i5-2500K, for example. Without the IGP enabled, this CPU pulls about 80W at 3.3 GHz. At a 33% overclock to 4.4 GHz (which most 2500Ks will do without any issue), and you're at no less than 106.6W.

Note, however, that I said "no less than." Clock speed increases thermal output linearly, but voltage increases it quadratically. A 2500K runs at about 1.3v, and I have my voltage set to 1.38v for 4.4 GHz. This 6.15% increase in voltage results in a 12.69% increase in TDP, pushing the CPU's TDP up to 120W.

So, a 33% overclock results in a 50% higher TDP in this case.

Because it is cheaper and AMD isn't pushing them.

Power consumption. Intel (and AMD) apply strict TDP limits and power consumption targets that allow motherboards and cooling solutions to be relatively cheap. There is a definite increase in TDP as you push past the clock speeds Intel and AMD use by default. That last 500-700 Mhz more than doubles the power consumption and cooling necessary which requires higher end current production from the motherboard, big ass coolers and a lot of extra noise to cool it all.

I also think Intel validates the clock speed of their CPUs a lot better than we are capable of, so you may find they aren't Intel 100% stable above those clock speeds but we can run them higher and somewhat unstable.

This isn't true. Doubling TDP takes a pretty extreme overclock. an i5-2500K at 5.0 GHz/1.45v (which, again, isn't very unusual) is only going to put out about 90% more heat than one at stock. Doubling output is certainly possible, but typical overclocks simply can't do it.

So is there a tool that u can use to determine at any given point the total wattage u are currently using system wide?
