Why OC when you have boost?

[Lhakryma]

So correct me if I'm wrong, but I always thought that boost is basically like OC, but not for all cores, but for a small number of cores (100% boost for the first one, 80% for the second one, etc.).

 

So in that case, for example for the 3900x that supposedly has a boost of 4.6 ghz, why would I bother with OC for low threaded software like games? Wouldn't boost be more than enough, since it would basically go to ~4.6 -4.3ghz for the 1-2 cores the games actually use?

 

From what I read, it should theoretically keep up the boost speed either until the load is down, or until it reaches a temp threshold (which with good cooling I'm guessing is never).

 

So unless I want to go past that 4.6 cap, why would I ever bother with OC?

For the most part, I've kept my Zen+ and above CPUs at XFR, PBO, or Auto OC. I only do all-core for benchmarking.

If you only play games that use 1 or 2 threads then that's your problem.

If you're happy with your performance, then there's no need to bother.

OC'ing 3rd gen ryzen is only really relevant if you do heavy mutithreaded work loads, not gaming. You could always do bclk overclocking though.

What's bclk oc?

I actually don't, TBH I recently started playing nms which maxes out literally every core on my cpu , I have an i5-4590 atm, wanna upgrade to 3950x for that sweet sweet multicore performance  

 

But from my experience, the majority of games (especially older ones) don't take advantage of all cores.

In my experience, pretty much all modern games are perfectly capable of using multiple cores. I dunno about indie-games, really, since there are very few indie-games I care about, though.

The way ryzen 3rd gen boosts overclocking is nearly pointless, their auto boosting behavior leaves very little room for improvement
E: A better focus would be getting good ram able to hit 3733/3800mhz as that will provide a significant speed boost due to ryzens archetecture

Could you please elaborate on that?

 

So the boost clocks will be consistent with proper cooling?

https://www.gamersnexus.net/industry/3495-hw-news-ram-prices-dive-binned-ryzen-3000 "Looking at the binning and overclocks, it confirms what almost all reviews have already: limited headroom for manual overclocking"

For precision boost behavior https://www.gamersnexus.net/guides/3491-explaining-precision-boost-overdrive-benchmarks-auto-oc that is yes with proper cooling you should expect consistent boost clocks, the colder you keep it, the better the clocks

As for the memory stuff I don't have a quick easy link at the moment and I really need to go to bed, but it's the same reason you always wanted fast ram for ryzen with an added twist that going over 3800mhz is a real kick in the nads

So then why do I see gaming benchmarks for 3900x using 4.1ghz OC, instead of just letting it use boost, which goes to 4.6?

cos, why not, its better to have multiple cores running at the same speed all the time, then all the lets care about the earth dynamic clock speeds and turbo

 

on a global scale, a few million overclocker's don't really count for nothing compared to the billions of processor's that are on 24/7
