Meet Intel's new flagship CPU, the Core i9 12900K. It is based on the Alder Lake architecture and is reviewed here. This time around, Intel was back at the drawing board, creating a completely new architecture that appears to work as advertised. This platform is poised for the future with its incredibly fast performance, DDR5 memory, and PCIe Gen 5.0 interface.

Thanks for the article, really enjoyed it. Will you be doing DDR4 v DDR5 at some point?
I'll be interested to see how the 8+0 12700k does for it's lower price, can the efficient cores be thrown away without much loss and how much power is saved over the 12900k? It's certainly cheaper of course.

What did you expect? This is very good and much better than 11th gen. You have to wonder what's the point of the i9 with the i5 so close and the 5900x/5950x still being highly competitive for workstation duty but overall 12th gen is a huge success for intel. They are putting pressure on AMD to make the next 6600x and 6800x cpus better for sure.
Well, colour me slightly disappointed. I expected more. A lot more.

Considering the small difference between the i5 and the i9 i don't expect much for the i7 i mean there's almost no room for it to shine.

@ Hilbert - Please do a DDR4 with TIGHT latencies at the same DDR5 speed so we can compare! 4800 or 5300 or whatever you can get your hands on.
You can just bench at 1080p to show the CPU scaling!

@Hilbert Hagedoorn Thanks for this great review.
But there is one important thing missing: 1% low frame rate.
I was also reading on another site, and they found that some games have significantly higher 1% low frame rates on Alder lake. Especially with DDR5.
This means that games will be a bit smoother to play on Alder Lake than on Zen3 or Rocket lake.
I'm guessing that the huge bandwidth of DDR5 helps with data streaming in some games.
