As we await the launch of Intel's "Arrow Lake-S" Core Ultra 200S series of processors for desktops, we are getting some new leaks about Intel's mainstream mobile "Arrow Lake-H" update. A month ago, we got the specification table of the high-end mobile "Arrow Lake-HX," and now, thanks to Jaykihn X, we have the mainstream laptop chip specifications as well. The top-of-the-line includes Intel Core Ultra 9 285H, a 45 W TDP SKU with six P-cores, eight E-cores, and two LPE cores. The CPU packs integrated Xe2 graphics with eight cores and 24 MB of total L3 cache and has a maximum boost of 5.4 GHz for P-cores.

Moving down the stack, there are Core Ultra 7 265H and Core Ultra 5 255H SKUs, which feature the same P/E/LPE core configuration. However, these SKUs are rated for 28 W TDP, having lower maximum frequencies and the same iGPU configuration. This time, we also have two Core Ultra 3 SKUs, with Core Ultra 3 235H and 225H bringing four P-cores, eight E-cores, and two LPE-cores in the 28 W package. The Core Ultra 3 235H has eight Xe2 cores in its iGPU, while the lowest-end Core Ultra 3 225H has only seven Xe2 iGPU cores. For a complete set of specifications, including all clock speeds in base and boost, please check out the table below.

Ahead of its October 23 release, PC enthusiast and Twitch streamer Madness727 released some of the first pictures of a de-lidded Core Ultra "Arrow Lake-S" desktop processor. There's no word on which processor model this is, but it shouldn't matter—all models being released this month are based on the same exact configuration of tiles of the "Arrow Lake-S," which means a Compute tile with an 8P+16E core CPU complex, a Graphics tile with 4 Xe cores, and the larger version of the breakout I/O tile that features an integrated Thunderbolt 4 controller.

Intel already released information on its Core Ultra "Arrow Lake-H" mobile processor that comes out in Q1-2025, which is shown featuring a physically smaller Compute tile that has a 6P+8E core CPU complex, a larger Graphics tile with 8 Xe cores, and a smaller breakout I/O tile. You can see where this is going for some of the cheaper Core Ultra 5 and Core Ultra 3 desktop processor models that release in Q1-2025. De-lidding is the process of removing the integrated heatspreader of a desktop processor to enable direct contact between the chip below, and the cooling solution. It is preferred by professional overclockers that use extreme cooling solutions.

Intel may have debuted its Hybrid (heterogeneous multicore) architecture for the desktop with the 12th Gen Core "Alder Lake-S," but the value-ended Core i3 series SKUs throughout the 12th, 13th, and 14th Gen Core processors have remained 4-core/8-thread traditional multicore chips, with just four P-cores. Intel is about to change this with the Core Ultra 200 series "Arrow Lake-S." According to OneRaichu, a reliable source with Intel leaks, the company is giving finishing touches to a pair of Core Ultra 3 series desktop processor SKUs based on the "Arrow Lake" microarchitecture. These will be 8-core chips, a doubling in core-count form the past generations, but the nature of these 8 cores is not yet known.

Among the SKUs in the leak are the Core Ultra 3 205, and the Core Ultra 3 215, both of which are 8-core chips. The two are probably differentiated in a similar manner to past generations of Intel Core i3 desktop did, using cache sizes (eg: Core i3-10100 and i3-10300). The chips probably feature a 4P+4E core configuration, as a "2P+6E" configuration might not be possible, as the E-core clusters are indivisible, although we don't know if the same rule applies to the "Skymont" E-core clusters. The dedicated L2 caches of both the P-cores and E-core clusters could be smaller than on Core Ultra 5 and above SKUs. The Core Ultra 200V "Lunar Lake" processor uses "Lion Cove" P-cores with 2.5 MB of L2 cache per core, while the Core Ultra 9 285K probably has "Lion Cove" P-cores with 3 MB of L2 cache per core.
