Intel "Raptor Lake Refresh" Confirmed with 14th Gen Core Model Numbering
Intel is giving its "Raptor Lake" client processor architecture an update in the second half of 2023, called simply "Raptor Lake Refresh." When we first heard about this development back in December 2022, there were two theories on how Intel could name these processors. The first one suggested that it would take the same path as "Coffee Lake Refresh" (9th Gen Core), and give "Raptor Lake Refresh" a whole new generational number scheme (14th Gen Core); while the other held that it would try to carve out new processor model numbers within the 13th Gen, like it did with "Haswell Refresh" (4th Gen Core).
Channel vendors in Taiwan are being communicated that the desktop "Raptor Lake Refresh-S" and mainstream notebook "Raptor Lake Refresh-H" will be the final generation of Core i processors (to retain the current nomenclature), and will be slotted as 14th Gen Core. The top desktop SKU could be named "Core i9-14900K," for example. The ultraportable "Raptor Lake Refresh-U" will be the first generation with the new nomenclature Core branding, while "Meteor Lake" will receive the Core Ultra branding, as it has next-generation CPU cores, iGPU, and an on-package AI accelerator.
As for what separates "Raptor Lake" apart from "Raptor Lake Refresh," we have a theory. Intel could implement the final refinements of its Intel 7 foundry node for the series; and generationally improve CPU core counts and cache sizes. The non-K 13th Gen Core i5 processors, for example, use the older generation die with 1.25 MB L2 cache per P-core, and 2 MB shared L2 cache per E-core cluster. Perhaps the 14th Gen Core i5 could be based on the newer silicon with 2 MB L2 cache per P-core, and 4 MB shared L2 cache per E-core cluster. We're not quite sure how Intel will segment the Core i7 and Core i9 SKUs. For 9th Gen "Coffee Lake Refresh," Intel had bumped up CPU core counts with the introduction of a new 8-core monolithic die, which allowed it to dial up CPU core counts for its Core i9 and Core i7 SKUs. The 10th Gen "Comet Lake" saw it introduce a 10-core die and the final refinements of the 14 nm process, to dial up CPU core/thread counts across the board.

“The 10th Gen "Comet Lake" saw it introduce a 10-core die and the final refinements of the 14 nm process, to dial up CPU core/thread counts across the board.”
my point is simply that rocket lake 11th gen was the final 14nm design.
I was always under the impression that Intel would bump core count, clock speed, memory support, and introduce that voltage regulator. The cache is another area where I think they could make changes, but I don't know if they will or not and just a bump to core count will add a bit more cache, but who knows if they'll try to increase the relative cache per core P core or per E core cluster. Perhaps another thing Intel will have adjusted is speedstep again to further refine it.
I still think if Intel did shared cache in P core clusters of 2 cores similar to the E core clusters with it's cache it would be a positive tweak. Doubling the HT thread count on P cores I could see as being a good direction potentially at least then the threat count on a P core would synchronize with the amount of cores in a E core and who knows maybe that works better with OS scheduler in turn.
I wonder if CPU cache's make use of PAM4 signaling or not!? Kind of weird implications if they don't already actively do so especially in the case of like X3D with a huge cache.
And I don't understand what is the point of the comparison in this topic. If you are satisfied with 12400 now, in 2-3 years you can upgrade to a more powerful.
Intel will never get their uArch cadence right. They just can’t admit even Pat’s timelines were misleading optimistic.
Funnily enough that Arm releases 10%+ IPC increases every year and their perf / GHz is already so much higher.
+ 200MHz P cores
+ 100MHz igp
+ 4 E cores
It is not worth upgrading from 12400 to 13400, but many may find 13400 interesting. In many multitasking applications, the 13400 is up to 30% faster.
14900ks=?+100w
If anything, if Intel can achieve 20-25% reduction in power and preserve or increase performance by some measure... that would be a big win! Hope the patent is not locked to mobile parts only, we "want" increased efficiency on the desktop. MORE efficiency, MORE cache, MORE clock freq and MORE memory^mhz = perfect combo for a 'refresh' and a welcomed addition!
