Since we already have the first Raptor Lake leak I'm thinking it should have it's own thread.
What do we know so far?
From Anandtech's Intel Process Roadmap articles from July:

Built on Intel 7 with upgraded FinFET
10-15% PPW (performance-per-watt)
Last non-tiled consumer CPU as Meteor Lake will be tiled

I'm guessing this will be a minor update to ADL with just a few microarchitecture changes to the cores. The larger change will be the new process refinement allowing 8+16 at the top of the stack.

Will it work with current z690 motherboards? If yes then that could be a major selling point for people to move to ADL rather than wait.

Just read over at Tom's that the 14700K is looking like 8+12 with all-core boost of 5.5.

Pretty much what we were expecting for the refresh. More cores at least for the lower specs and slightly increased clocks. If the pricing is right the 14700K could be a decent upgrade for some like me.

Very curious as to how the 14900K will compare to the 13900KS since the 13900KS will be tough to beat on the basis of frequency alone.

How about 10 or 20 of these all doing your video encoding jobs? Take up not much physical space and the power consumption should be acceptable, compared to a desktop CPU.

You want faster cores > then many cores in encoding unless its though NVENC or Quicksync.
Handbrake as i said tops out at about 6 cores if you do cpu encoding.
After that dimished returns hits really hard.


But again, encoding is so much better on quicksync and nvenc, that you're litterally watching paint peel off the walls if your still cpu encoding.

CPU transcoding is still the gold standard. Handbrake may top out near six cores for h.264, but not anything newer. CPU transcoding also gives you the best file size/quality. Quicksynch is good, and mighty useful. GPU encoding doesn't compare.

Max I've experienced is a 48 thread CPU encode. All cores seem to be utilized but only up to 50%. Speed wasn't that bad. With H.265 fastest encode, I was able to encode a full movie in about 20 minutes. I wish I owned a 5975WX.

Because a lot of it has to do with the codec and settings. Low resolution video doesn't scale very much, but if you are transcoding something at higher resolution using a slow preset, it will use as much as it can get.

but you get stupidily small returns for anything more then typically 6 core count.
And it only goes even more downhill as you go past 10.

Only if you re compressing one file at the time, if one has lot of files he can launch several instance of the compressing software, otherwise it s useless to have that much core counts CPUs...

It really depends on what and how you’re encoding.

Only the i7 has it's configuration changed.

Yeah, I shouldn't have said everything underneath gets a bump as I wouldn't expect every SKU to change in the refresh. I would expect that if Intel is doing a top to bottom refresh that other SKUs will get bumps (only the 3 are shown in the link) as Intel sees fit but we'll see what they do.
