You wrote "If taken at surface value, those differences look positive for the Intel Core i9-14900KF, but it needs to be remembered that single-thread scores are temporary peaks that ...likely have fewer use cases in real-world scenarios."

In fact, in real-world scenarios, the opposite is much more typically the case.  The overwheleming majority of programs remain single-threaded, and will thus benefit from higher SC speeds rather than higher MC perforance.  Furthermore, many workloads are bursty.  Thus higher SC speeds will translate directly into better responsiveness. 

By contrast, only a relatively small percentage of programs are written to take advantage of multi-core processors, for the simple reason that parallelizing complex tasks is very difficult.

Intel has disappointed everyone with the 14gen.
Its manufacturing continues at 10nm++++++ compared to AMD 4nm
The increase in frequencies causes overheating and greater energy consumption, the opposite in AMD
Intel 14gen without NPU, that is, without artificial intelligence, AMD has had it for 1 year.
14gen still does not update its iGPU against AMD with RDNA 2 RDNA 3 and now RDNA 3.5
Intel L3 Cache 36.00 MB AMD L3 Cache 64.00 MB the difference is very big.
Intel PCIe lines 20 AMD PCIe lines 24 larger in AMD
intel ISA Extensions SSE4.1, SSE4.2, AVX2, AVX2+
AMD ISA Extensions SSE4a, SSE4.1, SSE4.2,FMA3, AVX2, AVX512
Here AVX512 stands out that increases data performance
And finally the price Intel close to $700 AMD close to $350 practically half.
Shame on Intel Raptor-Lake S Refresh i9-14900KF could not surpass AMD Ryzen 9 7950X or Ryzen 9 7950X3D in overall desktop CPU performance and the worst thing is that this platform dies in 6 months with the arrival of the 15Gen of intel.

And most will still buy Intel. Because the ratio of production of processors for desktops and laptops is 5:1 in favor of Intel. In fact, in reality, prices for AMD chips are no less at retail, given their real catastrophic shortage, as for laptops with new series. And so every year. As long as Intel has 70% of the market, as does Microsoft in the x86 OS market, they have nothing to worry about - they will simply force you to use their products if there is no real affordable alternative nearby.

AMD laptop chips still have their drawbacks. Let me remind you that high-end AMD motherboards cost 1.5 times more than approximately the same motherboards for Intel. As a result, even if you save on the processor, the amount of the processor and motherboard will be no less than the kit with Intel. Moreover, AMD still does not have a complete analogue of TB4 in chips, as well as support for DP2.0+, the full version, only the poor UHBR10 mode (40Gbps), while Intel declares support for UHBR20 in both the 13 and 14 series using 2 DDI channels, allowing you to connect 8K monitors. They still cannot be connected to AMD, except with professional boards. As well as not connecting to any discrete card, which deliberately, due to the fault of AMD/NVidia, slows down the progress in the mass appearance on the market of 8K monitor models with perfectly clear text and graphics like on smartphones with high ppi.

The second reason why they are slowing down the introduction of DP2.0 ports at 80Gbps to the masses is banal - a shame in the x86 sector - their memory controllers in processors are 5(!) times slower than Apple controllers starting with M2 Max and 3 times slower than M2 Pro controllers . And slow RAM will lead to lags when working with 8K monitors, even in 2D mode. Realizing this is a complete shame - they are trying to slow down the DP2.0+ input for as long as possible, while panicking in parallel trying to speed up the memory controllers by at least 2-3 times...

By the way, ordinary people don't know, but stupid AMD, on its website, simply cannot find complete datasheets and full specifications of their processors/SoC of any series, unlike Intel, even in 2023. They are shooting themselves in the feet..

I easily found the full specifications for Raptor Lake, I can't find the same for the Zen4 series, although both Intel and AMD were released a year ago. They don't have these documents publicly available, even for Zen3/Zen3+!

What normal developer or student would contact AMD with this approach to the matter of disclosing information to interested specialists?
