Ah, I confused Tiger Lake with Rocket Lake; sorry about that.First I would recommend we keep this comparison to only desktop release dates(exclude out tiger[never came to desktop outside the NUC]) . This is simpler and more relevant, also Intel needs to keep to an annual cadence to keep the OEM's happy. Anything later than a year is thus late
Updating your dates to when i9 desktop top sku released
Coffee Lake (9th Gen): October 19, 2018
Comet Lake (10th Gen): April 30, 2020
Rocket Lake (11th Gen): March 30th, 2021
Alder Lake (12th Gen): November 4, 2021
Here we can see from coffee to comet Intel was late(10nm hiccup cannon lake...). Ever since comet release they have successfully quickened the cadence . I lived through this personally as I went from a 9900kf, to a 10850k, to 11700k to now a 12900k. The worst purchase of those was definitely the 11700k, the 12900k has been awesome, I am eagerly awaiting the 13900k.
For AMD Zen4 competition, Alder lake will be able to to hold its own even if eclipsed by AMD in performance, thanks to DDR4 compatibility as well as cheaper Motherboards (Intel seems to command the low end/budget builds at the moment). Raptor will help intel's position, extra e-cores is only going to help with select workloads, but the extra cache and improved IPC may help match/exceed Zen 4 performance. Either way should be an exciting year with good advancements from both camps bringing price/performance down.
Intel should have a better showing this Christmas than last year thanks to better supply. I was one of the few having a hard time finding a motherboard to match my 12900k as well as the ddr5 shortage. AMD supply is limiting their market penetration, looking forward to the reviews and concrete info on both.
As for everything else, I agee actually. I want to see them competing and lowering prices if possible due to that.
Intel will have its advantages and AMD will have theirs in their respective platform; that's the way it should be so we can choose.
Regards.
