Although Zen3 execution was extremely good and delivered more than expected performance, especially in games, the pricing is not exactly consumer friendly.
It is another thing to say that from a business perspective and in relation with what the competition has to offer it can be justified and another thing that AMD won't be like Intel and whenever has the opening it won't try to raise prices. It took Intel 4,5 years to raise the price of 2500K ($216) to the level of 6600K ($242)
$26 in 4,5 years and AMD $50 in 3,5 years (Although AMD increased their performance a little more in 3.5 years than what Intel did in 4.5 years, Intel had virtually no competition in that era, at +$200 there was no desirable competitive AMD CPU) On the other hand if you check the gaming performance, below is a pessimistic scenario of 720p difference in modern engines which possibly is more indicative regarding the future than 1080p CS:GO/LOL/DOTA2. (Intel % dif based on Techpowerup 720p results)
5900X 100
5800X 98
5600X 95
10900K 95 (-5% vs 5900X)
10850K 94.4
10700K 91.8
10600K 88.2
5900X is the easy choice to say that the +$50 is justified since it is a 12 core with no competition in the consumer grade CPUs from Intel for at least a year, but look also the 5800X model, it will be better than 10900K both in gaming and in multithreading applications like rendering (slightly) and possibly the 8 core Rocket Lake-S will not be able to match it in multithreading (in gaming the odds are with Intel I think) so why not $449 now? On the other hand $300 for a 6core is a hard pill to shallow, but if you check the inevitable 5600, having 10700K gaming performance and +20% multithreading performance in applications like rendering vs 10600K at possibly $249 is justified also. Another optimistic scenario involves also the possibility that the prices gradually will be lower than the SRPs. Anyway if AMD uses the extra margins to strengthen the GPU team I wouldn't mind, increased competition in the GPU space is badly needed and it will help the consumer also (especially after the mini preview, lol what a bad judgment call not to specify the RX6000 model positioning in the upcoming Big Navi models🙄)
