Tremont is about Ivy Bridge, not Haswell+.
It does really well in certain benchmarks like Geekbench and on there it approaches Haswell performance.
@uzzi38 6700K is 4.2GHz but they don't have to compare to the 6700K. If it's against the mobile parts it's pretty much a perf/clk comparison. They did say it's "higher IPC" than Skylake.
If you assume Golden Cove is 33% faster, than at 5GHz, that's 30% higher frequency and easily claim 50% better ST performance over Gracemont.
No, it doesn't. @dullard claimed Intel were running the Gracemonts close to the voltage floor which Golden Cove can't drop down to. That would be FAR less than 3.9GHz. Actually probably close to or below the 1.8GHz base clock you say here.
3.9GHz is close to the absolute maximum they can clock to full stop. It is very much high frequency for the Gracemont cores, even if not high frequency in relation to Golden Cove cores.
I don’t make the rumors I just read them:

It is entirely possible that Gracemont runs efficiently at 3.9 ghz. 10ESF is said to be 15% more efficient than 10SF.
However, I have always maintained that Alder Lake is about die area not power.
Sigh, fine then, lets just come back to this when the chips launch eh? We'll see how highly Gracemonts clock then, and we'll be able to judge from that then - whether or not we're well within the efficient point for the cores or if they're pushed near the max.
Remember the TPU clock vs. power comparisons of Zen 3 and Tigerlake-H? How Tigerlake-H favors higher end of the frequency curve? It's way different from every other CPU.
For example:
Gracemont seems to follow a typical pattern but Cove cores follow their own pattern. You cannot extrapolate frequency from the graphs they've shown because Gracemont and Golden Cove curves are very different. Gracemont is designed to be efficient at the low end of the frequency range and Golden Cove is efficient at the high end of the frequency range.
The fact that Zen 3 starts to lose at the higher end of clock and power means they are also using similar methodologies as everyone else.
With the Intel 22nm process, we got absolutely nothing on the desktop chips and even lost frequency. But it resulted in Silvermont being a great gain(indeed this is where they claimed 37% better performance).
Maybe they've shifted things back to the pre-22nm era for Cove cores.
@uzzi38 I expect overall higher performance per clock. Skylake has higher number of pipeline stages and the uop cache hit is not as high as they claim.
Skylake could be better in games? But in overall Gracemont should outperform it.\
My rough guess:
-3.3GHz Tremont
-3.6GHz process
-3.9GHz unrestrained power/voltage
As Dullard suggest I adjusted the x and y axis so the Intel 40% is achieved. If a max frequency was obtained could these power curves be converted to frequency vs performance? I mean if enough data points were recorded?
The graphs are marketing graphs and are meaningless. Surely you understand this.
Hey take it easy. Surely you understand not everyone is as smart as you.
I mean, come on, it is in the fine print…
(EDIT: yes I sense your sarcasm, I am just calling you out on it)

The CPU scored 1595 points in the single-core benchmark and 10170 points in the multi-core, which puts it at the very end of the single-core benchmark list compared to the latest Intel 11th Gen Core series (Rocket Lake) and AMD Ryzen 5000 Series (Zen3).
About as reliable as a benchmark can be when we have absolutely no clue about maximum boost clocks nor power consumption.Geekbench in what reliability nowaday?

Let me rephrase what @eek2121 tried to convey: these are not graphs, they are drawings. Rebuilding the axes is just as useful as applying lens correction on a painting.I'm using your language but the intent was serious.

It seems logical, so that's why the AVX512 is disabled on Alder Lake.
The dominant term is the Pdynamic: D * frequency * Vcc^2. You are correct that we need to know how frequency is a function of Vcc. In most cases, though, it is acceptable to assume that frequncy is proportional to Vcc. Thus the dominant term becomes E * Vcc^3.Old, somewhat complex power calculation from former member idontcare. The dominate term is Vcc (4th power). Of course, increases in voltage increase frequency. So knowing frequency = f(Vcc) would be a must.

They are actual graphs (note: of estimated performance which is different from final production performance) with the axis removed.Let me rephrase what @eek2121 tried to convey: these are not graphs, they are drawings. Rebuilding the axes is just as useful as applying lens correction on a painting.

I'm not sure where you got the 4th power from.
Some real bad sub scores right there for 12700. Looks like it is held back by memory subsystem, without knowing exact setup it's hard to say, but probably DDR5 4400CL40ish.
Core seems to be very potent tho, some subtests advance almost 50% vs Skylake.
Basically only the single core AES perf is doubtfull, although the MT AES score seems more or less in line.
Text Compression and Navigation subscores indicate real bad memory latency. Takes some horrible memory detuning to achieve scores as bad on Skylake.
On ST Cypress Cove has 10% frequency advantage here, and likely 15-20% on MT since the 11700K run at 4.8-5GHz all cores.

Also no AVX512 for ADL.
