what are Ryzen speed bins/ boost clock for individual cores?

AMD CPUs boost as much as possible,with all core boost too,it works similarly to how GPUs boost.

I can't find any information on the max boost clock for individual Ryzen cores. lets take 3700x for example. Base clock is 3.6 GHz and max boot for the fastest core is 4.4GHz. Whats the max bost clock for other 7 cores? surly it cant be 4.4 for all core then that would be just 4.4GHz overclock.(kind of)

that's the thing, precision boost scale differently on different CPUs even if the model is the same. It's too dynamic to give a proper number.

Every chip is different,some are better than others,the better chips require less voltage at same frequencies,so they will boost higher than others.

Intel has exact number for max boost clock for each core. for instant core i7 8700k individual boost clocks:

core 1 4.3 GHz

core 2 4.4 GHz

core 3 4.4 GHz

core 4 4.5 GHz

core 5 4.6 GHz

core 6 4.7 GHz

and base clock is 3.7 Ghz. 

 

why are't there slimier numbers for Ryzen chips

Like others said. Every chips is different. Also depends on your cooling solution.

 

Just for reference, it may not be the same for other 3900x. My 3900x with a 280mm rad will stay at ~4.55GHz for 1-2 cores heavy load. ~4.45GHz for 3-4 cores heavy load. And ~4.1 Ghz for all 12 cores load like Handbrake.

 

I run no PBO or auto-overclock.

Ryzen boost clock is temperature dependent. If you use a lesser cooler, the boost clock will be a little lower.

And chip quality dependent too.

3900x chips are binned. I see most of them will boost to about the same clock speed. +- 100MHz.

lets say we have the sufficient cooler. What AMD grantees each core will boost to considering no overclocking is applied. So, what are the official speed bins numbers for Rzyen chips?

I don't think there is an official number except base and maximum boost(one core, faction of a second). I've yet to see a 3900x boost all core below 4.0GHz when there is sufficient cooling. Although the base clock is only 3.8GHz.

I was looking on CPU benchmarks on the internet and it looks like stock AMD CPU are preforming much better then they should. Could it be possible that AMD CPU are dynamically boosting all core to max boost speed. Intel's mother boards have a setting called Enhanced Turbo which boosts all cores to max boost clock which you can manually enable or disable.

I use Gigabyte mobo. There is no such setting as far as I know as Enhance Turbo. Buildzoid made a video about Gigabyte BIOS. I watch the whole thing, and went through all the settings.

 

PBO and Auto -overclock in Ryzen Master only gives ~100MHz extra boost for all cores work load. It doesn't do much for 1 or 2 cores thing.

I use a Gigabyte motherboard too,I confirm there is no such option.

source? if that's the case then stock 3900x is just an overclock 4.6 GHZ 12 core CPU, given that there is enough cooling

It won't boost to all core 4.6GHz.

 

A good chip will do 4.4Ghz all core overclock. Mine can only do 4.3Ghz with 1.38v.

I said it boosts as much as possible,i didn't say it boosts to the max...

The boost numbers vary from chip to chip even if the model number is the same.

my point is how much better does it preform stock under best conditions and overclocked? not much as intel's overclocked CPU, because the are basically in a way overclocking at stock settings.

Under the best conditions with non-exotic cooling you will get 400MHz-600MHz higher clock speeds than the base clock
