Intel Core i5-12400 Early Review Dubs it a Game Changer
The upcoming Intel Core i5-12400 processor could be a game changer in the mid-range, according to an early gaming performance review by Igor's Lab, which landed simulated the chip by disabling the E-cores, and setting the right clock speeds and power values. Based on the smaller H0 silicon of "Alder Lake-S," which physically only features six "Golden Cove" CPU cores, and no "Gracemont" E-core clusters, the i5-12400 ticks at 2.50 GHz, and 4.40 GHz boost frequency, with 65 W base power, and 117 W maximum turbo power (MTP).
Testing reveals that this MTP value lends the processor some stellar energy-efficiency numbers, and the chip strikes a performance/Watt sweetspot. Igor's Lab, however, recommends that for the best efficiency, the i5-12400 should be paired with DDR4 memory. In its testing, DDR4-3733 (with Gear 1) was used. Gaming benchmarks put out by Igor's Lab shows that the Core i5-12400 trades blows with the AMD Ryzen 5 5600X "Zen 3" in a number of games, beating it in several of them by virtue of higher IPC of the "Golden Cove" cores, and beating the i7-11700K "Rocket Lake" 8-core/16-thread processor at a fraction of its power-draw. A word of caution, though, is that the i5-12400 was simulated on a C0 silicon, possibly the i9-12900K, and the real i5-12400 die may not have the same refinements or electrical characteristics. Even with the E-core cluster disabled, the L3 cache size isn't the same (30 MB vs. 18 MB). Catch the review in the source link below.

Honestly, looks good, but until they release budget to mid-range boards, who cares. Still you don't need DDR5, so only the Z690 board prices are stopping AL making sense at the moment.
Anyway, I'm waiting for RL, and looking forward to more E-cores, some of us don't just game. i7 13700K with 8 P cores, 8 E-cores. Also looking forward to Zen 4, 6800X.
For example the German idiom "blue miracle/wonder". The more or less exact translation must be "You will be shocked" or "to experience a surprise".
It came from an interesting, historical building, the "Lockwitz bridge" in Dresden (Germany). At the time of its construction, the bridge was one of the first of this span made of metal that did not require any piers in the river it spanned (in this case, the Elbe) - among other reasons, this is why it was called a miracle or wonder. The name "Blaues Wunder", in turn, is also due to the bridge's light blue paint, which is already mentioned in publications from the time of its construction in 1893. :D

What leaves me a bit in the dark about Alder Lake is Intel's strategy: One overpowers a really efficient CPU and just about achieves fictitious performance crowns, but unfortunately forgets that a significantly higher efficiency with comparable performance is much more valuable in the current time. However, this logic is of course difficult to comprehend for a company in a country where electricity flows cheaply and without limits from the socket. :D

Thank You, and, have a good day.
Someone asked me via mail for i3-12100, but I have no existing QS to compare and fine-tune a simulated CPU and so it makes no sense. Sorry :(
The ramdisk performance at 4096 unit allocation size with NTFS compression enabled between both chips is something comparing would be nice to see. I use NTFS compression all the time personally on SSD's you get more I/O and disk space. On a ramdisk you eliminate more of the disk storage bottleneck so you can really compare the CPU cache speed more readily combined with the compression. I like to use CompactGUI as well a bit to compress even further with some of the more CPU taxing compression techniques. I think with direct storage these compression scenario's will become a bit more relevant to discussion though to what extent I'm not so sure similar to Primo Cache I have to imagine.
You can't claim ADL is super efficient yet conveniently ignore the super premium DDR5 commands, without DDR5 I'm guessing perf/W gains would be middling at best.
