  City kids have friends, play outside and go visit friends.

Yes, and city kids also eat, poop, and talk. :)

I think it's the degree that matters.

  This is simply not true. If you look at social issues like alcoholism, drug use, suicides or domestic violence ... villages have plenty of those.

Degree matters here too.

AMD fanboys will back Intel if it’s against ARM.

They take full power and subtract idle power.

  >Which is why a naive perf/Watt metric like Notebookcheck does at each chip's top operating point is almost worthless for comparing efficiency.

It isn't worthless. It clearly gives a good enough picture on efficiency to draw conclusions. It's not like Apple and Qualcomm drastically slow their chips down in order to get better perf/watt. No. They have better raw performance than Intel's chips regardless of perf/watt.

You can't even get perf/watt curves on Apple's A series and M series of chips because it's impossible to manually control the wattage given to the SoC. On PCs, you can do that. But not on iPhones and Macs. Therefore, Geekerwan's curves are not real curves for Apple chips - just projections.

Geekbench shows the same gap in performance. Cinebench has historically favored Intel chips more than Arm.

I think Notebookcheck uses peak power in their perf/watt measurements.

They go over it in detail here: https://www.notebookcheck.net/Our-Test-Criteria.15394.0.html

It doesn't necessarily use half the power. But it does have greater than 2x in perf/watt and it has noticeably faster ST performance.

Actually, Apple's M3 and even Qualcomm's X Elite are significantly ahead of the new Intel chip in raw performance and especially perf/watt.

Cinebench R24 ST[0]:

* M3: 12.7 points/watt, 141 score

* X Elite: 9.3 points/watt, 123 score

* Intel Ultra 7 258V (new): 5.36 points/watt, 120 score

* AMD HX 370: 3.74 points/watt, 116 score

* AMD 8845HS: 3.1 points/watt, 102 score

* Intel 155H: 3.1 points/watt, 102 score

Cinebench R24 MT[0]:

* M3: 28.3 points/watt, 598 score

* X Elite: 22.6 points/watt, 1033 score

* AMD HX 370: 19.7 points/watt, 1213 score

* Intel Ultra 7 258V (new): 17.7 points/watt, 602 score

* AMD 8845HS: 14.8 points/watt, 912 score

* Intel 155H: 14.5 points/watt, 752 score

PCMark did a battery life comparison using identical Dell XPS 13s[1]:

* X Elite: 1,168 minutes, performance of 204,333 in Procyon Office

* Intel Ultra 7 256V (new): 1,253 minutes, performance of 123,000 in Procyon Office

* Meteor Lake 155H: 956 minutes, performance of 129,000 in Procyon Office

Basically, Intel's new chip has 7% more battery life than X Elite but the X Elite is 66% faster while on battery. In other words, Intel's new chip throttles heavily to get that battery life.

  >Of course they ignored things like node advantage, but who cares? ;)

Intel's new chip is using TSMC's N3B in the compute tile, same as M3 and better than X Elite's N4P.

  >Where are all those people who for years (or since M1) were claiming that x86 is dead because ARM ISA (magically) offers significantly better energy-efficiency than x86 ISA.

I'm still here.

The problem with the Nvidia replacement goal of big tech is that they don't have an ARM-like organization to design cores for them. Big tech use their own ARM CPUs because they use stock ARM core designs and its ISA. The hardwork was already done for big tech.

Big tech must design their own GPUs. From the looks of it, it's much harder to do it on your own than license cores from ARM.

Did you read my post from 4 years ago?

  Is AMD the king of the Titanic (x86)?

https://www.reddit.com/r/AMD_Stock/comments/kg4e8j/is_amd_th...

I basically outlined why I would not invest in AMD and it's inevitable that ARM would take over servers and personal computers.

>This is why you need unions.

What happens if the unions succeed in draining the profits, corporate has less money to invest in R&D, and a foreign efficient automaker comes in and takes all the market share away from the union-led automakers?

What happens then?

It's already proven that it's not just the node advantage. Just compare Apple's 7nm A series chips to Zen3 or M2 to Zen4. The power advantage for Apple is 3x - 10x.
