Raptor Lake Leaks + Intel 4 developments

The main increase is just going to be cache related though. Nothing ground breaking at all, it's not like they are 3D stacking a decent amount of it either. 
I do not think Intel will hit even 10% in IPC over ADL, peformance gains will be from increased clock speeds (Intels normal trick when laking innovation) and more cores. Apparent leak of the 12900KS price at 800$ also indicates Intel are returning to previous tactivs of drastically overcharging (people thought a £50 price hike by AMD was unacceptable lol). In fairness thoug i lso expect AMD to have a stronger memory controller than Intel as it will beexclusively DDR5 plus teh Architecture looks better

DDR5 seems like it's not even going to make a decent difference until higher speeds still come along, 6400 CL36 is pretty expensive. So by the time faster speeds come out and prices come down it will probably be later this year minimum, if not next year and then we'll be close to another new CPU being Meteor Lake.
I also have a feeling Intel might hold the single core performance over AMD, though i guess that's hard to predict anyway. If AMD have high pricing for Zen 4 i can see Intel having better price/performance again.

RPL doesn't look like anything to get excited about but on pure gaming performance, I think it will compete.
DDR5 pricing, pricing and features of both platforms in general, performance per watt and future upgradability will be deciding factors.

It's very likely RPL will be better value than Zen4 (assuming they both release this year) simply due to DDR4 controller on RPL and compatibility with what will be older Z690 motherboards when the Z790 boards launch.
You have to look it from the other perspetive, AM5 is future proof, there will be support for at least 2 next gen CPU-s, and while DDR5 is expensive, it will drive next gen cpu-s aswell. RPL will be last cpu for that platform, and also last cpu that will have hybrid controller so ddr4 users will need to buy new memory sticks too combined with buying whole new platform for upgrade which in the end would be more expensive than buying Zen 4 with ddr5 + support for next gen cpu-s.

Not necessarily. As I mentioned before, from the beginning Raptor Lake's P cores were rumoured to have a little tweak to them, giving IPC about a 5-10% increase. The tweaked core is suggested to be called Raptor Cove, and therefore imply (in true Intel fashion) that it's actually something new. Given Raptor Lake is supposed to incorporate that new energy saving tech Intel developed/acquired recently, it make sense to give the P cores a wee nudge to either help reduce power draw, or benefit from having a greater power budget available.
Well no, Raptor Lake looks to double the E core count, at least on the top end. 13900K will be 24c/32t
I think it will be a good upgrade for ppl on lower end 12th gen CPUs, but I think even the mid/low end Zen 4 CPUs will give Raptor Lake CPUs a run for their money.
The 6 core Zen 4 CPUs should offer some great bang for buck, just like the 5600X.

DDR5 did start coming down in price in the last few weeks, though seems to have levelled off. Having both DDR5 and DDR4 controllers was a very wise decision by Intel, one that would have been made years ago. I just can't understand why AMD didn't do the same with Zen4?

AMD is going to be fine supporting DDR5 only. It's still ~6 months away and as it's a new platform, they can start off fresh vs dragging ddr4 along.

Decisions are made long before release. Intel may have been stuck not knowing the exact state of DDR5 at the point they had to commit, AMD had a bit more time to see that state of play.
Also AMD tend to commit to a socket longer than Intel, not having to support DDR4 may make this easier.

AMD also still have a path to improve the AM4 market if they wish, and support the platform as entry level variant that is well established.
Z690 (support Alder Lake 12th gen & Raptor Lake 13th gen) is also a new platform, Intel still took the decision to include both DDR4 & DDR5 controller. Seems a no-brainer to me, especially considering how volatile the supply chain is.

ADL came out Nov last year. DDR5 was barely in production. Launching without DDR4 would be a disaster. Not to mention a major cost bump in adopting ADL due to DDR5 prices at the time and poor performance vs DD45.
There's a 10month+ gap between and ADL and Zen5. RPL is on the same upgrade cycle as ADL so keeping DDR4 support there is needed or you might as well have a net new platform.
DDR5 is still significantly more expensive than DDR4, I don't expect this to change in the next few months, especially considering current affairs in Europe.
By time Zen 4 comes it will be better, and AM5 will support at least 2-3 next gen cpu-s (not including Zen 4), so ddr5 will drive you for many years, while RPL is the last cpu for that plaform, and last platform that have hybrid controller so you have to pay for ddr4 and later ddr5 when buying new cpu, while with AMD you pay only for ddr5 and you are fine for many years. And also hybrid design have compromises, so i prefer clean ddr5 only controller.
