Makes you think what is the best method for cooling. Although, as it is all locked down then perhaps even a full loop won't help enough. Still may buy one out of curiosity.

As i said it will be more optimised for Zen 4. Kudos to AMD for the innovation, it can significantly boost gaming performance without architectural changes, i can't wait for Zen 4 to see it, ofcourse it all depends how good RPL is, if RPL fail then they won't need to release special 3d version.
Chiplet design allows them to pack more cores, and all big unlike Intel. RPL with monolithic 8 big cores and 16 small will have huge die size, which is costly.Rumour is still 16 core CPU but 5Ghz+ all core and 20 to 30% IPC
At 4.8Ghz a 5950X scores 32,393, with clock speed + IPC (lets say 25% over that 5950X) the 7950X should score 40,500, i think it will be tough for RTL to beat that and AMD aren't even adding cores. they still have that option.

I'd be supprised if it runs 5ghz all core in cinebench, AMDs demo said 5ghz but that was in a gaming workload so that would imply heavy workloads won't hit 5ghz.Rumour is still 16 core CPU but 5Ghz+ all core and 20 to 30% IPC

lol nah, go look at what the clock speed and IPC gain is between zen 2 and 3 and then compare r23 scores between 3950x and 5950x. 5950x is only scoring 20% higher score despite running several hundred MHz faster AND having 20% IPC advantage - since I own both I can also tell you that my 3950x with PBO turned on scores higher than my 5950x with PBO off
4.8 is not 5ghz though and even that's a stretch for most chips which tap out at 4.7, if the all core boost in gaming is 5ghz then you can bet the all core boost in heavy workloads will be less, even Intels 5.3ghz boosting chips struggle to hit 5ghz all core depending on the workload. Then there's trying to cool those small 5nm chiplets which if the TDP is increasing will be pulling more power.Getting my 5800X running all core 4.8Ghz in Cinebench is not difficult and people have done it with the 5950X, i can do it without unlocking the socket limits tho for the 5950X you certainly do, 4.7 - 4.8Ghz on Zen 3 in heavy workloads is already completely doable, in fact the 5800X runs at 4.6 to 4.7Ghz all core out of the box in Cinebench.
The extra 300Mhz is not so much an architecture limitation, tho 100 or 200Mhz might be with Zen 3, with a few tweaks and most importantly much higher power levels with the LGA socket yes i can see Zen 4 doing 5Ghz all core in heavy workloads, maybe even slightly higher, Zen 3 is almost there.
I doubt, it is only polished ADL based on the same node, quote from one site: "During its Investors Meeting event for 2022, Intel demoed an engineering sample of next-generation Raptor Lake, while promising up to double-digit performance uplift compared to today’s Alder Lake silicon. Reading between the lines, IPC is likely to increase by only a few per cent."4.8 is not 5ghz though and even that's a stretch for most chips which tap out at 4.7, if the all core boost in gaming is 5ghz then you can bet the all core boost in heavy workloads will be less, even Intels 5.3ghz boosting chips struggle to hit 5ghz all core depending on the workload.

The 13900k should score around 39000 as 8 Ecores will add 8000 then 10% IPC on top.

We know 8 Ecores adds around 8000 so the minimum score for RPL will be 35500 and that's just by adding Ecores, I'm sure there will be some IPC and clock improvements as like you say it's on the same node so will see refinements as the silicon quality improves.I doubt, it is only polished ADL based on the same node, quote from one site: "During its Investors Meeting event for 2022, Intel demoed an engineering sample of next-generation Raptor Lake, while promising up to double-digit performance uplift compared to today’s Alder Lake silicon.

So up to double digit performance uplift, hmmm.
Even if MT performance are similar it is still win for AMD, they dind't need to increase cores and change design which saves them money, while having tangible advantage in ST perfomance. As i said, Intel monolithic 8P + 16e cores will have huge die size, and then the cost of software optimizations for big/little. They will have to migrate to MCM design so they could add more P cores and completely eliminate those e cores which is painful from software perspective, and i'm quite sure they will kill big/little once they solve a challenge of creating MCM design.
I think there's a good chance Intel will offer better price/performance, not sure about their boards though. Not going to change platform to Raptor Lake when the boards won't allow any upgrades either, it's either Zen 4 or Meteor Lake for me so i can get at least 1 upgrade out of a new board.IMO all Intel needs to do with RPL is be close enough to Zen 4 while having the substantially cheaper platform costs.
They are a premium company, so customers were paying a premium priceThe new parts MSRPs really goes to show how much AMD was milking consumers with the original SKUs especially so given the subsequent TSMC price rises and the fact that AMD can still afford to cut 50% off the mainstream lineup and are making a profit.
Really? If so then you could say this about teh manufactureere of most products. How many price reductions do Playstations and Xbox have over there life cycle? Does this mean the Sony and Microsoft was milking the customer when laynching the product or where they covering R&D costs and production costs of a new product (which would decrease over time) most manufactureers reduce prices towards the end of a products life cycle. It is as simple as that

Lol, that was not the pointLol, how much of a CPU, MB, GPU, fast SSD, PSU and so on you'd buy from the same price of a console?
