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

[freeagent]

In my limited experience, if you take boost out of the equation and just run static clocks, they are about the same. I can run my 3770K at 4600 just fine, about the max daily all load clock I would run with it. My 5600X does 4600 just fine, and my 5900X does 4500 just fine, these are all load clocks. Like Linpack stable. With my 3770K moving to 4700 is not all load ready as it gets pretty warm, and my 5600X is the same way with 4700. My 5900 is the same with 4600, good for daily, cant run Linpack without hitting the upper 90s. But for BOINC or F@H its fine.

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...

That's pretty low of Intel to disable unlocked multipliers on their 4c/8t parts.

I'll have to look up some perf. benchmarks on the 12300f overclocked via BCLK (I can only imagine how high they had to go to get any significant overclocking).

BCLK overclocking is like dirty and bad overclocking it can be very unstable and stresses other parts of the PC.

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.

Is that on LN2 or some fancy cooling solution?

For $10 chip ha ha no way. Basic 3 heatpipe tower cooler + 2 x 120mm fan setup. These can hit 6 Ghz but they typically do work similar to what Ryzen can finish at 2Ghz

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?

Depends totally of the CPU, I've had only 7700K (4c/8t) reaching over 5GHz stable. But newer Intels with more cores clock to 5GHz or more almost always.

BCLK overclocking is like dirty and bad overclocking it can be very unstable and stresses other parts of the PC.

I don't see it like that, it's more an artificial limitation. I'd compare it to FSB overclocking which was common back in the day.

The hardware doesn’t care if you see it like that or not. I talked facts.

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

Cheap $15 CPU on a $10 Mobo

I can go even cheaper as I have few Pentium4 and Pentium D chips..

It's still an artificial limitation and I don't agree with you. BCLK OC can be fully stable and reliable as we've seen already with Skylake.

Ofc it can be, but it’s still a dirty and less reliable way of overclocking compared to multiplier OC, I didn’t say anything else.

They are going for far more than 10 dollars, more like 50-80 without shipping. Also good luck on hitting 6GHz with these with basic cooling like that.

Dont know, the problem is now days these higher core chips also get the better binned chips.

When I used to buy i5 chips they needed massive voltage and didnt have much headroom, then I remember seeing a graph posted by one of the reviewer sites showing the average voltage required for 5ghz between i5's and i7's over dozens of samples and was a clear obvious difference that showed the higher threaded chips are better binned, sure enough my 9900k runs at way lower voltage than any of my i5's ever did, and we know AMD do the same as their higher core count chips usually have higher clock speeds as well.

A 9900k better run at a lower voltage -- those CPU's had an infamously hot and power hungry reputation.
