Some info about desktop Alder Lake CPU specs, here:
https://www.techpowerup.com/284566/specs-of-top-intel-12th-gen-core-alder-lake-s-processors-surface

Looks like the top CPU (12900K) will be able to clock to 5ghz on 8 cores. The PL1 / PL2 power limits are very similar to the 10700K, at 125w and 228w, so I expect you will need an excellent air cooler (or water cooling if you prefer) to run all cores at 5ghz.

The PL2 is a bit lower than the Rocket Lake 11900K and 11700K, which have a PL2 of 251w.

I think the 12700K (also has 4 smaller cores) will probably be overclockable to 5ghz in some cases too (since the 12700K can turbo to 5ghz on +1 cores). It might be worth buying a pre-tested one from the silicon lottery website, when these become available.

Overall, probably about a 10% performance boost for higher clocks (my CPU runs around 4.6ghz on all cores) and perhaps another 20% for IPC and cache improvements, vs Comet Lake.

If you have an Intel CPU clocked at 5ghz already, the performance improvements might not be massive.

I wonder if they will do an Alder Lake CPU, released a bit later with just 8 cores (and no smaller cores)?

Oh well, they've reached 6400mhz on DDR5 at least, which is about 1000mhz higher than I was expecting for Alder Lake. It seems to be struggling a bit, considering that it appears to up against 3200mhz RAM.

I still think most gamers would be better off with 4x4GB of quad channel DDR4 RAM, at least until the latencies of DDR5 are improved.

It would be pretty slick to be able to do this on my current RAM, so that there would be no need to upgrade it (thats why they won't standardise quad channel DDR4 motherboards instead then!)

Zen 4's platform /AM5 should be a better option for people who might want to upgrade after 2-3 years.

Plus, AMD they will have some CPU models that run at reasonable temps without a really beefy cooler, assuming they improve power efficiency by using a 5nm EUV fab. process.

Bonus points if they standardised quad channel memory on mid /high end boards...
