Intel Core i7-14700K has an 8P+12E Core Configuration
The upcoming Core i7-14700K "Raptor Lake Refresh" processor has a core configuration of 8P+12E. That's 8 "Raptor Cove" performance cores, and 12 "Gracemont" efficiency cores spread across 3 E-core clusters. Compared to the i7-13700K, which has been carved out of the "Raptor Lake-S" silicon by disabling 2 out of the 4 available E-core clusters and reducing the L3 cache size to 30 MB from the 36 MB present; the i7-14700K gets an additional E-core cluster, and increases the shared L3 cache size to 33 MB, besides dialing up the clock speeds on both the P-cores and E-cores in comparison to the i7-13700K.
The processor likely has a P-core base frequency of 3.70 GHz, with a 5.50 GHz P-core maximum boost. In comparison, the i7-13700K tops out at 5.40 GHz P-core boost. An alleged i7-14700K engineering sample in the wild has been put through Cinebench R23, where it scores 2192 points in the single-threaded test, and 36296 points in the multi-threaded test. The processor also scored 14988.5 points in the CPU-Z Bench multi-threaded test. Intel is expected to release its 14th Gen Core "Raptor Lake Refresh" desktop processors some time in October 2023.

A genuine query.... W T F is intel doing? These now look more like server/workstation/encoding chips.... why not cut cost, cut thermals, cut power consumption and just drop another 8C 16T i7 variant without the E?
Or is Intel just lost in competing for the higher MT score card?
Reduced cache? Where X3D has excelled Intel is reducing memory.
I don't get it... unless 14th Gen earns great points with efficiency, power consumption and significantly superior ST performance uplift - doesn't excite me.
So you have Xeons with P-cores only and you will have Xeons with E-cores only.
Although, technically there are slow and fast cores in SP Xeons for quite a while. Not all cores are capable of reaching max turbo. I don't know whether Windows or Linux schedulers know about this.
AMD should have offered hybrid design from the get go with AM4 IMO. 7920X 12 Zen 4 + 4 Zen 4c for example and 4c cores have SMT unlike Gracemont E cores.
I'm a i7-7700K and 9700K carrier for gaming mostly single threaded workloads. The first is a quad MT and the latter ST 8 cores - all Ps by design. Now we're compelled to buy into the e-core surplus and most of us don't even need it. I don't believe for a second this is a well-intentioned endeavour to serve the productivity/server space.... it seems like a distressed endeavour to remain relevant on the score sheet (obviously some will benefit significantly but others have to pay the added premium to keep the wheels greased for the minority).
And in case your wondering I don't any Intel cpus, both my PC run AMD.
It seems to me 6 p-cores respond well to more juice (which Intels design can take) but 8 p-cores is on the verge of meltdown so going the 6 p-core++++++++ e-cores route makes sense until they can engineer their way into performance competitiveness more effectively without needing to push more power into their chips which AMD can't really do. Perhaps 14th gen is where 8-pcores are more feasible finally?
13th gen seems to be competitive I don't recall why e-cores are so controversial. I understand obviously it was to compete with AMD in core count and getting the upper hand in Cenebench scores. Early renditions were lackluster and Intel needed moar power to flex enough not to be completely outshined by Ryzen.
I'm willing to try an e-core cpu perhaps next year but a bit nervous what board to pick and how to tamp the power levels down to normal if the board is over juiced if nothing better so I can objectively compare the Intel vs. AMD experience for myself. Even the 12600/12700/12900 seems pretty respectable in terms of price/performance ratio at the moment although I'm more interested in trying a 13th gen chip.
So much complaints about e-cores I don't get why there aren't more complaints about duel chiplet Ryzens having the 2nd gimped chiplet instead of a separate sku that features two perfect chiplets. I think to be fair 16 AMD p-cores are not the same. The 2nd chiplet of 8 cores tends to be weaker but you can kind of mitigate that with curve optimizer based on something I read recently.
more like quality vs quantity.
If ecores are so great for gaming they should have used only ecores for their CPUs. Well Intel didnt. So I guess these ecores are good for some tasks not all.
By using a hybrid design they can advertise much higher number of cores, not just eliminating AMD's marketing advantage but turning it around and making it their advantage and in some occasions where P cores are sleeping, while E cores doing the light work, advertise high efficiency, even when in fact their CPUs are much more power hungry.
So, why add more P cores? Most if not all apps are more than happy with 8 P cores and multithreading apps will show a high score thanks to having a much higher number of cores when utilizing all of those E cores.
Intel will start integrating more P cores when it's CPUs start losing in benchmarks because of it. If games start getting optimized for 10 or 12 cores, Intel will have to offer something with more P cores. Until then they have no reason to add one P core in place of 4 E cores. The average consumer will buy a 24 Cores CPU( 8+16 ) over an 18 Cores CPU ( 10 + 8 ) at the same price.
Obviously the lithography still matters - TSMC is already making Apple chips on 3nm and we have nothing from intel on their 7nm process, that they're calling 5, because marketing slides.
Hopefully they gain some steam through 2024-2026 with stacked nanosheet.
The 14900K may very well be the most underwhelming of all in this refresh, at best equal to the 13900KS but I'd argue it's probably still going to be a small step down
And how many "locked E-cores" has an i5 12600K?.....
Better yet, how many "locked or unlocked" E-Cores does intel stick on one CPU these days?..
:laugh:
(lol)
Nah, i'm just tired of seeing Intel going nuts over core counts and completely destroying the once treasured performance tiers. At the cost of inefficiency and power guzzling, and the core-voluminous tax on top. Obviously for some odd reason some will show signs of resentment, but there is absolutely no harm in suggesting non-E variants at a competitive price alongside the BIG.little subgroup minority feeder.
Unless 14th Gen picks up some solid points in the efficiency/PowC dept and we're not tied into scheduling misadventures, we got something worth shouting about. Otherwise, so far not impressed! Oooh can't be bothered with doubled up CCDs either. Heat hoggers!
TBF, for me the preferred CPU must check all the following boxes: competitive perf with the top dogs (doesn't have to be the best), courteous efficiency/low power power consumption, easy to cool and reasonably priced. For me thats normally the i5/r5 or i7/r7 segment. I'm a simple man with simple desires and when things get out of shape it doesn't wash well with me.
AMDs not in the clear either... the slow boots, SOC hi's, XMP/EXPO playing up, user-input in some cases being a requirement to touch on advanced configs (although i dont mind) and on top the slow take off thanks to AMDs silly higher AM5 premium.
I was meaning to swap from intel to AM5 and sadly even the slow boots was enough to steer me away (for now). I'm open to either camp if they get the full package on point.
