4 core/8 thread CPU's better overclocking potential than CPU's with > 4c/8t?

[80251]

My SB-E 3820 only seemed to beat out my 5820k in overclocking ability, but in general do 4c/8t CPU's have significantly higher overclocking margins than CPU's having more cores?

No.

8350 at 5.0 on air which is a 125W part beating out the 220W parts requiring water lol.

forget 4c/8t, 4c/4t is even better

A bit higher yes. Less cores means, less cores have to achieve the higher clock, means the probability for the overclocks success is higher. Extreme overclockers usually disable cores to achieve higher clocks, same reason.

Huh? @ 5.0Ghz it would be drinking more than 125w, I know, have the same chip & board as yourself unless you are EXTREMELY lucky in the silicon lottery.

Do you disable cores in the BIOS? I've heard of peeps disabling hyperthreading but I didn't know you could also disable cores.

Is that on LN2 or some fancy cooling solution?

I just bought them at microcenter back in 2014, you should see my air cooler (Ashura) it never froze in Ryzen Blender either.

Yes I know but to have a 125W chip do it on Air only is a feat in itself.

Yea, both helps.

Gaming on my 11th gen i7, I disable HT - it's useless with the current state of game engines. I've gamed with it enabled but did not see an increase in fps.

It was proven in a couple of vids, virtual cores are for work, not gaming lol

Depends on the game engine. There are games out there that use more than 8 threads but they do not interest me.
Besides, without HT, can get higher core clocks/ringbus with less heat.

 

[80251]

Even if games can't make use of hyperthreading the OS should be able to and if the OS is running more efficiently because of it wouldn't it be best to leave hyperthreading enabled?

 

[xtreemchaos]

yes, most 7700ks will go to 5ghz 0r 5.2 ghz on water without too much fuss.

Yep I game on me 8 P-cores only. Plenty fast enough with the speedy Golden Cove cores. Can OC higher also with less heat and power.

If I need to thread something ill just turn them on.

I bet it's just some basic 92mm or 120mm tower. Those chips are notoriously easy to clock high. It's not Intel or Ryzen crap that burns everything at 5GHz.

It seems like among the latest Intel Alderlake CPU's the ones with the highest max turbo frequency aren't the 4-core or even 6-core models but the 16 core models? For example, the 10-core i5-12600K, which has a max turbo frequency of 4.9 Ghz. while the 4-core i5 and i3 models on have a max turbo frequency of 4.7Ghz. The i9 Alderlakes (at least the 16-core model) have a max turbo frequency of 5.5 Ghz and the i7 Alderlakes 5.10 Ghz. I would've figured the exact opposite? Or maybe max turbo frequency has nothing to do with the overclocking margins of a given CPU?

You should have bought the 8-core i7 9700K
(no hyperthreading)

It's almost like, Intel want you to buy the higher end chips because their margins are much better?

Who'd have thunk it ?

My guess is that those lower end chips can be OC way above frequency of more expensive parts ? Tell me I'm wrong?

Then again, I'm rocking an 8 year old 4790k @ 4.6 in one rig with a 6800xt, 4k, suits my needs fine.

Any unlocked newer 4c 8t chip should be even better I'd think.

So Intel cherry picks out the best performers for their high core parts and the worst parts have cores disabled and are pawned off as I3's and I5's?

 

[TheoneandonlyMrK]

Not usually but the odd line and chip do buck that trend.
Golden samples are sprinkled everywhere after all.

I returned an 8700k for a 9700k and after looking at the article cited here it looks like I made a mistake because on average the 8700k is slightly faster than the 9700k in most gaming scenarios.

The higher end chips have better IMCs for overclocking memory. At least with current & past generation. This of course appeals to enthusiasts.

Not if the CPU only has 2-4 cores, then SMT is a must have.

They are more or less even, SMT is like a 20% performance uplift, 2 extra cores, very comparable, but I would prefer the 9900K over both. You did a sidegrade there

They deliberately don't have the stock boost on cheaper chips higher than the parts with more cores, which are much more expensive. When technically, they'll be able to clock higher...

You'll find you can overclock chips with fewer cores to higher frequencies than the high end parts. Which is why Intel don't offer unlocked multiplier on 4c 8t... now

12300f has been pushed using bclk to massive frequencies, oh for a 12300k...
