Depends on the context, in general we use the perf/watt but if you want to see the efficiency at a specific performance or the performance you can get at iso power then just perf/watt desnt mean much.

In his case, he lowered the TDP for one CPU (PL1 125W) and left the other CPU at a higher TDP of 141W. Why not lower both CPU TDPs and measure the efficiency again ???
Fair point, but I think the test was more about the "unnecessary" stock power being pumped into the i9. It even performed better, in some cases, with the 125w power limit. Are we claiming that Ryzen 3 also performs better (not in efficiency) with less than stock power? ADL-S beat Zen 3 across the stack in many of these tests, from i5 to i9, that's not an efficiency test; that's raw stock performance. That the 12900k could do it at half stock power, is the efficiency cake on top. I don't see where being slower and efficient is attractive in these tests.

Update:

I updated the Asus 690A to the latest bios and installed fresh WIndows 11. I got better scores in Cinebench R23 and lower Wattage use.

Single Core test = 1899 at 68 watts power drawn from wall

Multi Score test = 17267 at 167 watts power drawn from wall

Not sure if the new bios or the fresh install made this happen

Also, my idle power draw is like 35 watts

Hey anyone having an issue when you press your power button it takes like 3ish seconds before the pc starts to boot? I have a 3-4ish second delay after hitting my power button. Mobo is Asus Hero z690 with a 12900k

After building my setup, the power button turned it on but it did not boot. VGA light was on although this has an IGPU. I put a GPU in it and it was the same. I removed the GPU and just waited for it to boot. It took more than 10 seconds to finally get it to boot first. After that, its been good.

Thanks wound up reseating my gpu and replugged the front panel connections in. works fine now.

Now Intel has a competitor and they are doing what was the hard overclocking work. That being figuring out what max frequency the CPU can safely operate (under warranty) and at what required voltage. In fact, you can even set power limits, which limit how far you want to push the part. Sounds great right? Intel had pre-tested their CPU's to within an inch of their lives and by simply setting unlimited power and providing adequate cooling you can eek every bit of performance out of your CPU. Or you can forego that last 10% or so of performance and cap power use at 125W, or 150W, or whatever.
There is no need for intel to bin every single CPU and make individual settings and put them into each CPU <--That's what you are saying here because a normal bin still has plenty of variance.

Modern CPUs do that by themselves they can monitor temps and power and adjust clocks to the best possible point without anybody ever looking at them.
When AMD announced ZEN they called it AMDsenseMI with neural network prediction and everybody was all like how amazing it's going to be (did anything actually happen with that or did AMD just drop it) , intel does the same and suddenly it's "Intel had pre-tested their CPU's to within an inch of their lives"

Here's a pretty impressive GB5 score for the 12600K: (ST 1960)

This trounces my pretty decent 5800x score (ST 1828)
https://browser.geekbench.com/v5/cpu/10826841 (SMT disabled, which seems to give trivially higher ST score)

Edit: My 5800x is running a very fast 3-year old Linux kernel (4.10, the fastest kernel I've found). The 12600K score is on Windows 11 Pro.

Certain CPUs are actually inefficient at lower power levels, though this may not be the case with Alder Lake.

That is the highest single thread score I've seen on a 5800x.

My CO is more tuned for higher multi and SMT is on.

Cinebench R23 scores i9 12900k at 35W with 2-p cores disabled(maybe to simulate top laptop variant of Alder Lake) vs M1 Max.
14288 vs 12326.


Looking like Alder Lake mobile will compete quite well against Apple M1 variants.

Well of course. People act like the M1 is 10X more efficient than x86. They compare year old chips on an old node to a brand new product on a cutting edge node.

Hopefully AMD is pivoting to > 8 cores in a laptop.

I should try to set the PPT on my 5950X to 30W and see what it scores.

People also forget that a lot of Apple's advantage comes from the people making both the hardware and software working together and having a common goal. While that doesn't have as much of an effect on third party software, it does mean that the people writing the system software and the APIs are going to be able to take much more advantage of the silicon or even work with the people developing it to include certain features to help optimize the performance.

And by the way this is extremely good compared to TGL-H 8C, roughly 2x improvement in perf/watt at 35W. And this is ADL-S, the mobile targeted ADL-P might work even better.

Did the stock 5.2ghz single core and 5ghz all core "boost" give it away?

Thought the boost was 'only' 4.9GHz
Anyway, clock speeds alone are arbitrary without context. I'm sure most could have guessed the 12900K was so far along the efficiency curve that it was basically 'off the charts' (in a bad way of course) but the undervolting just confirmed it.

Personally, I would much prefer a 125W 12900K running at ~4.5GHz all core. You're literally doubling power to get that last ~10% performance. Whatever it takes to get that 1st place on the benchmark charts, I guess...

HWUB - 12600K Review.
My favorite of the bunch (because I'm poor). I'd wait for B660 MB, and use DDR4 to keep costs down:


Matches 5800X performance and power usage.

The 12600K offers great value on its own, but is let down by the lack of cheaper motherboards like you said. Something doesn't seem right when the motherboard costs as much as the CPU itself.

The 12700K is also a good value IMO. Once you factor in platform costs, the $150 difference doesn't seem as big, relatively. If you're one to keep your PC for a long time without upgrading, I actually think the 12700K is the better deal.

ADL-P would need to achieve at least 6123 points to have the same perf/W as this ADL-S.
It will depend on how high the clockspeed can be kept.

It's like this every release. Intel releases K CPUs and Z boards. I have the patience to wait for a B board.

And the 12600K is massive overkill for me, so no need to look further up the chain.

OK tried CPU-Z benchmark on my i5-12600K

Single Thread uses 78 watts from the wall with a score of 789.6
Multi Thread uses 141 watts with a score of 7203.2

Looks like i beat an i9-11900K with lower wattage use LOL.

Tempted to grab a 12xxxk for a new gaming build but paying the same for a basic board as what my X99 cost is kinda off putting.

Sorry. I didn't know the VID x frequency was the same for each CPU. I thought those parameters were tested/determined during binning for each CPU.

I'm feeling somewhat vindicated after arguing with people in the comments section of the 12th gen coverage lol. I bet the real deal ADL mobile will be even better. Hopefully they offer LPDDR5 too to save power on memory. Imagine what this would be like on 5nm. Intel still has it in them to win the CPU race

Right now the only chips out are the top end ones and in limited supply. The people buying these are the ones who will also spend a lot on an expensive board. Cheaper options will come with the release of the low-end and mid-range parts.

Call it the early adopter tax or whatever you will, but it's always like this. Let's just be happy that Intel has something worth the price for a change.
