Initial test results
i7 2600k, Savage of the Goon League
vs
Ryzen 7600x
Unfortunately conversely Red Dead 2
vs
That said I noticed in the Red Dead benchmark that my CPU frequency barely broke 3k at any time, and at around 22% activity usage
Metro Exodus runs about the same
Meanwhile on a plus side, some MMOs are seeing much better floor and averages
And Conan Exiles has a literal 30+ fps uplift even in intensive areas

I am also dabbling around with trying to keep the stock 5400mhz while bringing down voltage/wattage
All the rage is to use Precision Boost and a curve optimizer. Based on initial testing fortunately -30 curve
I started to notice that the clocks no longer reached 5400, as if 'boost' was no longer enabled. Possibly it only applies to single core/thread work?
I have to set manual clocks to 5400 to over ride that, though get the impression that PBO in a manner of speaking intelligently (due to the settings) finds a way to 'afford' the ability to boost higher with as little resource requirement as needed.
Setting a manual voltage might -if not diminish this - make it a moot point.
Saw this in an article which (While I am still learning/reading about the Zen platform features, still struggling to understand)
- You effectively tell the CPU that it needs less voltage for a given frequency. And, as a consequence, at a given voltage, it can apply a higher frequency. So, when the Precision Boost 2 algorithm determines sufficient power and temperature headroom to use 1.35V, with the negative point offset, it will target a higher frequency.
- The CPU temperature will be lower because you use less voltage at a given frequency. That extra thermal headroom will also encourage the Precision Boost algorithm to target higher voltages and frequencies.
Yet trying to understand what the direct correlation is between this feature and reduced boost. I can see there's an option to set a manual boost override, once you've set a curve optimizer setting - however it only goes up +200, therefore maximum 5000mhz
I thought the idea was that PBO + Core Optimizer results in boosting to go higher not lower.
The above would make me think that it would be applying a higher frequency, yet as stated before, my standard 5400 clock drops to 4700
Thermal is not an issue thus far, not hitting the thermal limit (which I put down to 75)[ though I am of course wanting to reduce voltage/wattage/heat where possible while retaining most of the standard clock frequency).
PPT, TDC and EDC should allow that with a compromise to performance of course though again heat is not the issue currently.
Besides, most of the articles indicate they use Motherboard or Manual values for the above which sees the PPT up to 1000..so how is that meant to improve thermals via PBO and negative Curve?
Then thought about foregoing any curve optimizer, thermal limit etc. and just good ol' fashioned Vcore style undervolting, while retaining highest possible clocks.
I can do 5450 at 1.1v though funny enough outside of Cinebench, none of my games force a 5400 clock, they're all sub 5k - meaning I wonder what is the point then.
Also partially confused about is the terminology of "Boost clock" - it doesn't seem to be mutually exclusive to simple 'clocks.'
The "4800" aforementioned is the maximum frequency when the curve optimizer is enabled [negative], there's no boost beyond it and it's at the clock speed it runs at in operation( as opposed to 4.5k which is a standard clock that occasionally jumps to 4.8k as a 'boost').
Could be it is semantic, however I'd like to get as close to 5.4k stock while also reducing voltage some/heat/wattage - and thus far best has been to just set a 1.050 - 1.1 v manually
Maybe I am misunderstanding how the PBO and Core Optimizer /curve is meant to work or that the clock speed between 4.7 to 5.4 is irrelevant as no standard game will be forcing 5.4 or anywhere close to that frequency very consistently.
If all games are going to use such little CPU %/clocks than ya, the simple PBO+Curve seems an easy approach yet comes still at a temperature/wattage/voltage cost.
In summary the recommendations of undervolting through use of PBO and Curve Optimization doesn't seem to be nearly effective as simply lowering your voltage outright
