i7-7700 vs i7-7700k

[SHOOKSHOOKe]

I accidently bought i7-7700 and already used it. So this comes from my own regret.
Is 7700k that much better than 7700? price difference is only about 30$.
(I am not into overclocking)

What I am saying is the way it works is that effectively they disable, they run far far lower to allow one to be boosted, which is why even an overclock to the boost speed of a CPU can be really effective, as such describing it as disabling the other cores is an easy and accurate enough way of describing what the difference is between the states and chips.
Honestly, I feel Intel shouldn't even sell locked versions on the top chip of each line, you loose to much performance for a minor saving.

Yes, this is perfectly right.
To be precise, all C-states (except C0) are idle states (unlike P-states). So when specific core is in idle state it doesn't do anything. Because it has nothing to do - otherwise it wouldn't be IDLE state. And, accordingly, consume fewer power than usually.

The 4.5GHz Turboboost for the 7700K is only on one core while 3 cores are deactivated to transfer the TDP to allow that one core to run higher.

Cores cannot be "deactivated". Such functionality doesn't exist (and cannot exist because of obvious reasons).

> Most modern AMD/Intel CPUs for MANY years now have this option for most of those CPUs in a Motherboard's bios that allow you to manually select just how many Cores you wish to always have active; as a manual over-ride. For example if I wanted to use a modern CPU and play older stuff (legacy stuff) I can enter the bios and knock the CPU down to maybe 2 Cores and then I can achieve better single Core IPC for legacy stuff.

> Core Parking

So-called "Core parking" in Windows OS is very simple feature - it just tell OS to NEVER schedule any task to the "parked" cores. The same as Linux "echo 0 > /sys/devices/system/cpu/cpu[0-9]+/online". This effectively turns core to C7 power state mode. It can be done via ACPI so user can use BIOS settings as well.

[Bad 💀 Motha]

Yes I understand its not the same as Core Disable; cause it's just a power saving on/off feature for on-demand usage, to avoid all cores running needlessly all the time, I get that.

But the rest of the info I pointed out is also true and you can enter your BIOS and disable extra cores if u wish. On many CPUs, they are designed to where the less cores active = the higher the base/turbo can possibly operate at. It can be useful depending on what all you're doing.

Another question...since when is turbo boost good? Isnt it always better oc at your own and the correct voltages?

Do you even know what Turbo Boost is?

[Monk]

Yes, but you can't overclock a non K chip or on a non z series board, so the effectiveness of a boost clock between the 7700 and 7700k counts. If you can overclock the chip, boosting it even so all cores operate at the boost clock is highly effective.

Yea boost 1-2cores...you know manually oc?abtility for all cores

Question was for unlocked..i never buy a locked model
But today i think oc is useless(cpu)..for games my rig is undervolted lower temps less noise only thinking about flash my rx480 as rx580 again for better perfomance
So im just wondering that people still use it for gaming or similar

Thanks for confiming you don't know what it exactly is.

Undervolting is daft, if you have a decent cooler, the noise level isn't bad and you just give up performance.

Overclocking will increase performance quite significantly in some cases.

Undervolting because games cant bring my cpu at limit so why wasting energy for unused perfomance? (Im not playing newest AAA games..and no Games from EA)my pc dont make much noise but any noise is too much...anyway i will stay at air)

Explain why you thinking that i dont know it
