how much boost does overclocking a cpu will give in all tasks except gaming!!!

[xxxhomie21]

hey there
what are the real advantages of OCing a proccy over a non ocing one
i've researched and found that it will increase frames in games i.e around 10~12 (only if gpu is capable of more) and some more scores in benches i.e Cinebench, firestike etc

so does it only provide small inc in performance and crazy inc in GHZ and can only be used for show off in friend circle

i'm fed up by knowing that the unlocked one will cost more,requires aftermarket cooler and will eat my mind for settings i can save that money and invest in my gpu

i think that 4790 will worth more than the K version of it

If overclocking can give me very much performance boost than how much i want to know the real world benches mainly in rendering, editing and also gaming

-note-
i'm not posting this on oc thread as the enthusiasts will try to change my mind

depends on the program or game. if the game is limited by the gpu than you will see almost no difference however if its a single core heavy program or game their will be a large increase in performance.

Just buy whatever you can afford. don't worry about what others have.

Hey,
1) For video it's really complicated, so I'm just going to give you a BEST CASE SCENARIO using Handbrake.

Handbrake is almost completely proportional to the overclock. Thus, if we overclock it by 10% we get the video done 10% faster. The default max Turbo for the i7-4790K is 4.4GHz, and for the i7-4790 it is 4GHz.

So 10%, though you can go as high as 4.8GHz if you win the "silicon lottery) and your motherboard, settings, and cooler are all adequate and setup. I don't personally push things to the limit, and as you said that needs a much better CPU cooler.

So, up to 20% is possible. 10 to 15% more practical.

Other editing programs are often more limited by the speed of one of the cores not total processing power for much of the editing process (final render may be more like the Handbrake example.)

2) You can also TWEAK the CPU even if it's non-overclockable. I have an i7-3770K but this probably still applies->

*You can adjust the TURBO values. For example, on an i7-4790 the max Turbo of 4GHz might only be for one main core usage. So you may see FOUR different multipliers such as 40, 39, 38, 37. Thus running at roughly 3.7GHz when rendering video (you can look at TASK MANAGER).

On my i7-3770K I did a quick overclock (no voltage), adjusted my multipliers and I run at 4.2GHz (full load) instead of the default 3.6GHz in the same situation.

3) GAMING?
Not really.
In general, with your CPU it's not going to make much difference at all. If the CPU is fast enough (it's usually the main thread of code that's the issue) then running the CPU even faster doesn't make a difference.

In the 2013 Tomb Raider, look at the big graph to see what CPU SCALING looks like:
http://www.techspot.com/review/645-tomb-raider-performance/page5.html

Now look at Fallout 4 which is very poorly optimized. Really not acceptable:
http://www.gamersnexus.net/game-bench/2182-fallout-4-cpu-benchmark-huge-performance-difference

*You can see a big difference between an i7-4790K and i5-4690K. A big part of the difference is the 500MHz default frequency difference but it's relevant to your question (The "4GHz" for the i7 is the non-Turbo speed so it's probably running about 4.1GHz in reality as per my discussion near the top about turbo). It's really NOT common to see a gaming need for more than an i5-4690 or similar though.

It completely varies by the game. If you'd had a weaker CPU like the FX-4300 and a good GPU the difference between games can be well over 40% vs a modern Intel (like minimal bottleneck in Tomb Raider, but big bottlenecks in some MMO's, Skyrim, Starcraft 2 and others).

4) i5 vs i7->
A faster i5 can make sense as well, especially if it saves a $100 or so.

The i7 mainly benefits really well threaded workloads, however being able to overclock a similar i5 can give similar or even better performance in some circumstances.

$100 for a GPU on the other hand goes a long way.

5) CPU cooler->
You didn't ask, however my top two recommendations for budget coolers (for a modern i5/i7) are:
a) Cooler Master Hyper 212 EVO
b) Cryorig H7

The H7 is my top choice. The "EVO" is okay but the fan gets noisier than I'd like. Far better than stock though. You also need to adjust the fan profile (usually the motherboard fan software).

6) System Memory must be fast enough to prevent CPU bottleneck. Do not use one stick only. I generally recommend->
i5/i7 4xxx-> DDR3, 1866 or 2133 CAS9 (2x4GB, or 2x8GB kit).

i5/i7 6xxx (Skylake)-> DDR4, 2666MHz CL16 (or close; there was a pretty in-depth article, but pricing doesn't affect total PC cost much. Maybe $15 or so for a better 16GB kit.)

7) What about SKYLAKE CPU's?
Maybe an i5-6600K?

Depends on total budget, and difference in cost to a similar Haswell setup. There's a few advantages you may or may not care about but that's too long as I made a book already with my post.

*You MIGHT want to consider building without an addon GPU first and get an AMD Polaris or NVidia Pascal card instead. My MAIN reasons for this are:
a) AMD-> current GPU's put out a lot of heat (my room would get too warm), but

b) NVidia-> performance loss due to lack of ASync Compute hardware for future DX12 titles is uncertain. We won't have RELIABLE information for a while, but we have some indications with two beta titles (Hitman, AotS). It's NOT clear how much NVidia can tweak their drivers.

Both of the new architectures are not only really power efficient, but we'll also see future games use their hardware much better (put another way, current GPU's won't do as well comparatively in future titles).

*It's not a BAD thing to buy now. I'm still rocking a GTX680 and love it (similar to GTX770), but for me it's not nearly good enough for some upcoming titles including STAR CITIZEN.

Here's a GPU comparison (averaged over a lot of games)->
https://www.techpowerup.com/reviews/EVGA/GTX_950_SSC/30.html

$120 difference is roughly difference between a GTX960 and GTX970 (i.e. an i5 instead of i7 CPU). But look at the performance difference.

Thankz photonboy for such ans it answered my other ques too

but i'll prefer non unlocked one as i can compromise one or two games for price to performance ratio i.e fallout 4

but another thing which confused me is "however being able to overclock a similar i5 can give similar or even better performance in some circumstances."
line does really ocing can make that much difference tell me some more

i5 vs i7:
I'll just give you an example of how a faster i5 beats a slightly slower i7.

Starcraft 2 only uses TWO CORES. So you want the fastest two cores you can get.

Hyperthreading is confusing, but you can consider it a bit like the i7 having four extra, but slower, cores. Basically each real core can run another thread of code during the time its getting more data so you can get up to 40% more performance but ONLY if the game or program can utilize that.

So the i7 might have 40% more performance theoretically at the same frequency, but in reality if the game only uses two cores they'll operate the same.

(I won't go into some issues before where a few games would stutter with an i7, but I believe that was due to using the hyperthread instead of a main core to run some of the code).

*So again, a game like Starcraft 2 which only uses two cores will operate best on the CPU with the highest frequency (same architecture).

**The i7 will benefit games that use more processing than the i5 can deliver which is pretty rare but does happen, and of course with PROGRAMS like Handbrake which can use all of what most CPU's can deliver at times during the conversion process.

Hope that isn't too confusing.
