With the release of Alder Lake less than a week away and the "Lakes" thread having turned into a nightmare to navigate I thought it might be a good time to start a discussion thread solely for Alder Lake.
It certainly make sense, or the unexpected wonders of CPU upgrades.
Info - Asus, Gigabyte and Asrock adding Vermeer and Renoir support to A320 boards. (Update: 1.2.0.7 adds Cezanne support to 300 series)
Early this month they started to make the bios avalible to all models, but only to A320 boards, B350 and X370 were left out because they are EOL and A320 is still in production. Not sure why Vermeer, it would have been better to have Cezanne. EDIT: MSI updated to ComboPI 1.1.0.0 with the bios...forums.anandtech.com
AMD only stands a chance in battery life with RMB, on pure performance Intel holds the lead.
My comment had more to do with CPU performance in the 45 W -H segment.I think they'll take MT CPU, iGPU, and battery life lead on the 15W sector, and 28W sector up to maybe 4+8. AMD currently has a massive MT leadership on the subportable parts, something Intel will need to overcome first.

Well you can see the improvement in battery life in the review. It's not too far behind last year's 5900HX model of the same laptop, which is a decent improvement over Tiger Lake-H.Yup. I thought I would add to it. They aren't so bad on the -H. Perhaps Alderlake will make it actually competitive on perf/watt, not just performance.
The on-package PCH should in theory help with battery life over Tigerlake-H. Again in theory.
Good lol, because these performance numbers makes me more certain than ever that there'll be a crossover point between Rembrandt and 6+8 in that 28-45W region when it comes to MT performance.My comment had more to do with CPU performance in the 45 W -H segment.
That previous massive MT leadership is partially based on TGL-U being a 4C/8T part vs the 8C/16T of the -Hs, while AMD used the same 8C/16T dies from ultraportable right to DTR designs. That doesn't apply this round as both Intel and AMD will be using the same respective sets of parts (14C/20T or 8C/16Ts) in at least some of their T&Ls which would be used in gaming/DTR notebooks, so ADL-H's MT prowess should in theory translate well to ADL-P.I think they'll take MT CPU, iGPU, and battery life lead on the 15W sector, and 28W sector up to maybe 4+8. AMD currently has a massive MT leadership on the subportable parts, something Intel will need to overcome first.
Most Cezanne-H laptops have a short-duration turbo higher than the TDP, typically 65 W for the 5800H in your most popular models. Since this is R20, not R23 which runs for 10 minutes - how do we know that the power consumed during the run in this graph isn't 65 W?Some context for that last post: scores are identical to 45W locked 5800H. 5900HX takes a 10% lead. I expect the 6900HX will have a slightly larger lead than that again over the 12700H, and should be similar to 12900HK

At 40W it does about 4500 pts.
There s a graph for CB power comsumption in the review below, idle is at 10W and loading at 58W, all measured at the main, this amount to 40W at most at the CPU level.
Morefine S500+ in review: AMD Ryzen 9 5900HX with 32 GB of RAM and a 1 TB SSD in Mini PC
We review the Morefine S500+ Mini PC with the AMD Ryzen 9 5900HX, 32 GB of RAM, and a 1 TB SSD.www.notebookcheck.net
So power efficency of 6 + 8 ADL is comparable to Cezanne at this level, RMB should exceed 5000 pts at 45W and will be a tougher comparison.
Like Minisforum, Morefine also offers different settings in the BIOS (10-, 15-, 25-, 35-, 45-, and 54 watts) when it comes to the SoC's TDP. The AMD Ryzen 9 5900HX is used with 45 watts by default. However, the SoC can also be run with 54 watts. We performed all benchmarks with the increased TDP to enable a better comparison
Except in the review they explicitly said:
And Prime 95 + CB R15 showed the whole device taking ~70w of power in CPU-heavy workloads, not 58w..
Phoronix has some interesting results
Phoronix has some interesting results with its Linux testing OpenBenchmarking suite.
With latest Linux kernel and recent compiler it seems 12900K has no trouble beating 5950x in *most* of the tests. 10% extra performance.
I would not read into power efficiency results too much as Ryzen system had 96W average usage and Intel 97.4W.
Except of course Intel used internal GPU and AMD had RX6800. So Intel in its "Designed by Marketing morons" SKU delivers 10% extra performance for 20-25% extra system level power.

Real competitor for 5950X on Linux seems to be 12700, ~90% of performance for half the price at very similar power levels.
The whole device is not the CPU, that s measurements at the main with idle power being 10W, so 70W amount to 46W at the CPU level.
Their measurements show that the chip doesnt get to 54W during Cinebench, power measured at the main is about 58W during this bench and amount to barely 40W CPU power.
That s tests that rely on few threads, dunno what are they and how compiled they were..
On a lot of tests the 5700G perform about the same as a 5950X but once it s optimised for more than 8 cores the difference is staggering and the 12900K left in the dust.
Are we looking at the same review?

They clearly measured the device maxing at 68-70w during a cpu-heavy workload, including Cinebench.

5700G with it's single CCD and 16MB of L3, but on-die IMC beating multi CCD desktop monster.
A single threaded or so bench, so that s assuming that the system is loaded only with this app, wonder why multicore systems would be necessary.
You can check other benches, there s a boat load that are lowly threaded.
