Good luck with rdna3, the GN review said the 7950x is using double the power of the 5950x (120 vs 250). I havn't got to performance uplift yet but wanna be good for double power.

edit: 26% more performance for double the power use and temp pinned at 95c. Not sure with the increased cost on mobo and ram to get here this is great. Kinda feels like an Intel release.

It feels pretty meh. Not that the CPUs are bad or anything, but they basically held back on giving us something truly great so they can re-release them later as 3D which is going to be the CPU to get for gaming. Making a big leap and then going back to doing things the old way for your supposed next generation product is lame from a consumer standpoint.

So 12 gen Intel still killing it?
I told people that AMDs 7600X is a banger vs the 12900K was just clever wording.
They werent actually gonna completely walk 12th gen.

13th gen even with a minor minor uplift in performance will easily take the crown they never lost back.

Still waiting on those X3D chips though.
Im almost certainly going DDR5 for my next full build.
So whichever chip gives me bang for buck gets my money.

Being able to buy a year old Mother Board and a 13700 base is very tempting though.
Overclocking CPUs is practically pointless these days, and i dont memory overclock either so the base i7 is looking very tempting.

Just price them correct Intel.

See my above post. Rendering and synthetic benchmarks (where they max out all cores/threads) are a MUCH different workload than gaming.

For real-world gaming scenarios, Ryzen 7000 (and Intel 12th gen) consume less power and deliver more performance than their previous generation equivalents.

It's pointless on these cpus, they straight up run to the thermal limit. You might be able to get something out of it with undervollting cores to get a little more bang for your thermal limit but hardly worth it.

the 7950x is using more than the the 5950x in your image and the 5800x3d is using less power than the 7700x (seeing there is no 5700x to compare against)
 
So, AMD has caught up to Intel's 12th gen performance at 10nm with their own 5nm process, meanwhile, Intel's 13th gen is on it's way, still 10nm and will more than likely come out on top.

Pretty much.
The same with GPUs honestly.


The fun of overclocking for me is actually the opposite as now I try to lower voltages to try and gain or atleast NOT lose performance.
Actually alot more fun seeing how low a chip can go and still perform the same.

Memory OC'ing is still actually quite interesting but fuck it, im too old and too lazy.

My hot take is that it’s a good CPU but kinda boring from a gaming perspective.

If you’ve already got an AM4 platform, might as well just get a 5800X3D and call it a day.

If you’re in the market for a new platform (new motherboard + DDR5), makes a lot more sense to wait for Intel 13th gen + the 3D VCache Zen4 and choose between those.

Gamers Nexus....250 watt power draw, more than the 12900K in their testing...WOW!

95 degrees C is crazy. What happened with these current CPUs and TDP and heat.

Yeah but the Intel CPU is drawing 300W to achieve near (more like less) the performance level of Zen 4.

Ahh Prime95 that program literally no one uses.

These tests are fully academic, cuz no one is actually gonna be running Prime95 to do anything.

In a gaming system power consumption isnt that drastic.
And even if you are CPU rendering (you really shouldnt be GPU rendering is amazing these days) you arent running much hotter/higher voltages.

AMD, Intel and NVidia are all pushing clocks as high as they can, to leave no performance on the table.
Power consumption doesn't scale linearly with clock speeds. It's closer to a geometric increase.

There is also the issue with smaller die size. As chips get smaller with new process nodes, the contacta area with cooler or shim, gets smaller, and this limits heat transfer.
It also seems like the HIS on these Zen4 CPUs might be a limiting factor. Delidding might become an important factor for enthusiasts with Zen4.

Good thing we're on a gaming forum.
Word.
Tis why the 12400F is still a king of the hill in terms of bang for buck CPUs.
We are gaming side, we dont really care about Prime95.
But in gaming the 12400F and 5800X3D are pretty much golden children.

When AMD eventually releases 7800X3D it will probably take the crown as best gaming CPU.

As someone who’s been dying to play Civilization 6 at 4K 180FPS w/ minimum graphics setting, 7950x looks like the CPU for me.

Thanks, Anandtech!!

This.

You shouldn't compare these CPU to the 5800X3D series, but to the 5000 in general.

The 3D series is coming and they'll be the real benchmark vs Intel.
