CPU-Z Screenshot of Alleged Intel Core Ultra 9 285K "Arrow Lake" ES Surfaces, Confirms Intel 4 Process
A CPU-Z screenshot of an alleged Intel Core Ultra 9 285K "Arrow Lake-S" desktop processor engineering sample is doing rounds on social media, thanks to wxnod. CPU-Z identifies the chip with an Intel Core Ultra case badge with the deep shade of blue associated with the Core Ultra 9 brand extension, which hints at this being the top Core Ultra 9 285K processor model, we know it's the "K" or "KF" SKU looking at its processor base power reading of 125 W. The chip is built in the upcoming Intel Socket LGA1851. CPU-Z displays the process node as 7 nm, which corresponds with the Intel 4 foundry node.
Intel is using the same Intel 4 foundry node for "Arrow Lake-S" as the compute tile of its "Meteor Lake" processor. Intel 4 offers power efficiency and performance comparable to 4 nm nodes from TSMC, although it is physically a 7 nm node. Likewise, the Intel 3 node is physically 5 nm. If you recall, the main logic tile of "Lunar Lake" is being built on the TSMC N3P (3 nm) node. This means that Intel is really gunning for performance/Watt with "Lunar Lake," to get as close to the Apple M3 Pro as possible.
"Arrow Lake" features the same "Lion Cove" P-cores and "Skymont" E-cores as "Lunar Lake," but connected differently. In "Lunar Lake," the P-core complex sits on its own tiny ringbus with an exclusive L3 cache; with the E-core clusters being separated into low-power islands. The two core types talk to each other over the chip's high bandwidth fabric. In "Arrow Lake," however, the "Lion Cove" P-cores and "Skymont" E-core clusters share a ringbus and L3 cache, like the two core types do on current "Raptor Lake" chips. Intel will innovate with the way the P-cores and E-core clusters are physically arranged along the ringbus, and you can read all about it in our older article.
Back to the CPU-Z screenshot, and we're shown a clock speed of 5.00 GHz. This is likely being read off the first "Lion Cove" P-core. The P-cores have 48 KB of L1 Data (L1D) and 64 KB of L1 Instructions (L1I) caches; while the E-cores have 32 KB of L1D and 64 KB of L1I caches. We've known since the "Lunar Lake" technical deep-dive from Intel's comments, that the "Lion Cove" P-cores on "Arrow Lake" will get 3 MB of dedicated L2 caches, compared to 2.5 MB per core on "Lunar Lake." Each of the four "Skymont" E-core clusters of "Arrow Lake" shares 4 MB of L2 cache among the four cores in the cluster.
The total L2 cache on "Arrow Lake-S" is 40 MB. This is from eight 3 MB caches from the P-cores, and four 4 MB caches from the E-core clusters (24 MB + 16 MB). We are now learning that the shared L3 cache size remains 36 MB on "Arrow Lake."
Since the "Lion Cove" P-cores lack HyperThreading, "Arrow Lake-S" is a 24-core/24-thread processor. The generational performance gain over the current Core i9-14900K will boil down to the ~14% IPC gain of "Lion Cove" over "Redwood Cove" (which in-turn was within 2% of "Raptor Cove"); and the massive 38-68% IPC improvement of the "Skymont" E-core over the "Crestmont" E-core (which in turn was +8% over "Gracemont.").
Intel is expected to debut the Core Ultra 200 series "Arrow Lake-S" desktop processors, and the LGA1851 platform led by the Intel Z890 chipset, around late-September or early-October, 2024.

The stack according to both amd's and intel's naming scheme is i5 13600k vs R5 7600x , i7 13700k vs R7 7700x and i9 13900k vs r9 7900x. Those cpus launched at very similar (actually, besides the 900k, they were identical) MSRPs and names.
Now with the new naming schemes i'm kinda confused about what's what so we have to see
If the name (xx900x vs x900x) isn't enough to tell you what's competing with what, then just check the msrps. It's kinda obvious, no?
Read more, write less, especially about things which you don't understand.
I played around with the Intel Core i9-13900K to see how it stacks up against the latest AMD Ryzen 7000 Series – specifically the flagship AMD Ryzen 9 7950X – to give you a better understanding of which CPU comes out on top, and which one you should invest in.

No, i5 (u5 now) also have deep blue shade
And this screenshot is on the new i5, otherwise, the author of this fake screenshot wouldn't work so hard to hide every clue that this is i5
But I mean come on, before you buy any product you should make a bit of research.Well that's different, nobody says the CPUs should be unsafe. What i'm saying is the K cpus should and traditionally have targeted performance and not efficiency. If it's efficiency you are after (out of the box i mean) you go for the normal non k chips. You might even save a few bucks.
I think the issue is intel isn't sending those chips to reviewers, god knows why, cause I think non k would be way more appealing to the majority of the end users.
Naturally, I always go for the non-K version because I care more about the few bucks saved than having 1% higher boost when power limits are unlocked. But this doesn't mean that K variants shouldn't be safe and stable at stock.
Like saying .. no you must wait .. something MUCH better is coming. Then when it finally comes, it turns out to be nothing special,
It works in the other way, advert OC guys they'll have to DIY. K does not mean overclocker, it's unlocked.
Not that I care - it's just funny how much of a noise they made about it then had to drop it...
Are they using the gracemont E cores in this or newer crestmont ones? I thought Intel said they were gonna bring it back with the next E core range....
