AMD Ryzen 7 7700X

[Mussels]

Am I missing something here? Or do the graphs show that overclocked setting is using less power, running slower, and colder than stock setting?
It looks like the OC and Stock numbers are switched in those graphs? I don't understand.

No, those are all correct


An all core overclock can not achieve the same as letting boost do its thing, so when you're at lower clock speeds they run lower voltages and run colder, and get lower performance.
Only synthetic multi threaded tests get faster, stock or tweaked PBO give better gaming performance but with higher voltages and temperatures.

Got my 7700x at 5.65 ghz on all cores overclock on air with Noctua D15 and x670e strix-i mobo FYI via ai overclocking.

Well I just bought a 5800X3D for $266 USA Dollars

CInebench R23 score, multi and single?

All core OC at 5.65? I want to see Prime95, choose any of the default 3 presets.

Bummer. I was looking to get the 7700K but it looks like it runs so hot and with so much more electrical consumption than the 5800X3D or even the 7600X.

This might exceed what my current ~130-150W TDP cooler is capable of and will turn my room a bit too toasty.

It is a shame that the more power efficient settings isn't enabled by default.

Does anyone know why the power consumption figures for the 7700X seem to be all over the place depending on the review? Techpowerup and Tomshardware benchmarks both show the 7700X use about 30-40w more than the 5800X3D at stock in multithreaded benchmarks.

But then other places like Guru3D shows the 700X consume 10 watts less than the 5800X3D.

Then get the plain 7700 (without the X).

The 7700X is actually cheaper in my area than the non-X 7700 due to sales, combo deals, etc.

The 7700X runs at its hard limit of either 142 W, or 95 °C, whichever it hits sooner in your setup. The 7800X3D eats around 80 W max in a Cinebench all-core workload.

I agree with the above, get the non-X, even if it's a tad more expensive. Or the X3D.

Edit: Also, the TDP rating of coolers goes out of the window with Ryzen.

Some people measure actual power consumption with test equipment, others rely on the software sensors, which are often completely wrong

7700x and 7700 are both 8 core chips. 7700x is set for maximum watt and 7700 is set to watt where it is the most power efficient.

you can set this yourself, so just buy the cheaper one unless you are afraid of setting anything in bios

BTW we are talking full cpu load - for example while gaming those draw max ~60watt (which is below the limit for both)

If you want the 7700X to operate like a 7700, just turn on eco mode

 

[HD64G]

All Zen3 and Zen4 cpus are easily configurable within the UEFI just by setting a power limit exactly where your cooling system can handle. Half an hour is enough to test and find the sweet spot.

So get that and turn on Eco mode.
I collected some info from a 7950x video on YT for this reason:

7950x Eco modes (All core clock + temps then GN CPU test render time in seconds)
65W TDP / 88W PPT (4050MHz 40.3) 8.0s
105W TDP / 158W PPT(4800MHz 62c) 6.4s (25% faster)
170W TDP / 262W PPT (5100Mz 95c) 6.0s (33% faster / 6.6% faster)

Each of these CPU's has a point where they pass their efficiency curve, if you stick to the 105W TDP setting you'll be fine for 99% of uses on Zen4.
Nothing stops you putting your own PBO values in, AM4 is best with that done as well.

That 6.6% difference for 104W could likely be achieved without any extra wattage with minor undervolting, different motherboards will utterly change how these values behave as a board with more vdroop will actually be more efficient at multithreaded load - the current trend is for boards to pump more voltage than needed to 'help' overclocking but it tends to just make them run hotter and slower.
