If I wanted to start piecing together stuff for a 9900k what would be the ram I'd want to look at? I have an old ivy bridge, so I know I'd need to upgrade to ddr4. I'd want some good ram, as I'd be overclocking the cpu. I just haven't done a build in 5 years so the specifics to current chips I'm a bit out of date on.

3000/3200 is the sweet spot right $/performance right now.

Make your move...'cause mine's gonna be ugly.

2666 is the new base RAM speed of the 8th and 9th gen CPUs, but if it's what you already have, use it.

We're suggesting 3000 and 3200 in the building thread, with 34-3600 only suggested if the kit is on a board's QVL sheet and priced right.

I don't know if they're doing it or I'm wasting my time but I don't know if there's super high latency DDR4 or if it matters. Like 2666-19 or something high like that, I don't want to lead someone wrong, but maybe it's not like DDR3? I remember 1600-15 kits for that that were slower than normal 1333-8 kits.

Cannon Lake is never launching on desktop, so you might be waitin' a while!

tbh, its getting to the point that I don't think we will ever see Ice Lake either.

I remember a few months ago Ashraf Eassa was suggesting Intel should scrap 10nm and move on to 7nm, is there any credence to that or was it just conjecture?

So where do they go once they hit 7nm?

In the short term at the high end, some combination of MCM, bigger dies, lower profits, and/or higher prices.

I think I remember reading that 5nm is a hard wall thermoelectrically with existing technology, and the only thing they can really do short of some revolutionary tech and/or exotic materials is just keep adding cores and cache.

This article describes 3nm and smaller, but it seems to be overly optimistic: https://semiengineering.com/transis...ons-beyond-3nm/

I'm really out of the loop on how Intel is doing re: CPU technology and I always thought that Intel was the absolute king but this doesn't seem to be true anymore. What's a good and accessible (I'm not a hardware engineer) article I can read to get myself up to speed on what Intel did wrong and what everyone else did right?

Very cool, thanks for that!

I think itís going to be a very interesting next couple of years in the cpu biz. I expect intel to do a few more frantic acquisitions to try and diversify or improve their portfolio.

Wasn't one of the tricks in the bag still was gutting x86 or rather large sections devoted to compatibility?

No, that's not really an issue for modern processors. Space is taken up by cache and VLIW style execution units inside each core. If you take a look at a processor image with a block diagram over it you'll see that decode is a very small segment of the die.

The core adjacent to the iGPU is consistently 5c-10c lower on certain gens of intel CPUs.

Do you see where I'm going with this?

I'm still kinda stunned at how good this is. Normally there's some inconsequential minor point that I can trash, but there's none of those. There's some things I could add, but the biggest would be Marvell.
