The official press release
Intel Core Ultra “Arrow Lake-S” desktop processors are expected to appear later this year, bringing the new Lion Cove P-cores, along with Skymont E-cores, to the desktop platform . is already in the hands of PC OEMs and motherboard suppliers, given the number of leaks in recent days, Jaykihn0, one of the most influential sources of these leaks, has revealed some interesting details about the maximum increase frequency of these chips.
The QS of the flagship Core Ultra 9 “Arrow Lake-S” SKU, possibly the highest model to succeed the current Core i9-14900K, is defined as a maximum P-core boost frequency of 5.70 GHz, and all- P – Core boost frequency of 5.40 GHz is the highest E-core boost frequency, which is also the all-E-core boost frequency, we unpack this using the same combination of ‘Lion Cove’ P -cores and ‘Skymont’ E-cores like ‘Lunar Lake’, although they are arranged on a ring bus, and share an L3 cache, unlike ‘Lunar Lake’, where the L3 cache is dedicated The P-cores have their own, and the E-cores are arranged in a low-power island, with the SoC tile fabric connecting the two.
We know from Intel’s “Lunar Lake” deep dive, that the company claims a 14% IPC advantage for “Lion Cove” over the previous generation “Redwood Cove” P-core in ” Meteor Lake”. Since “Redwood Cove” cores have been proven in the real world to provide roughly the same IPC as the “Raptor Cove” P-cores powering “Raptor Lake”, if Intel’s IPC claims for “Lion Cove ” accurate, then the P. -cores of “Arrow Lake-S” at 5.70 GHz should be 14% faster than “Raptor Cove”. It is worth noting here that “Lion Cove” cores lack Hyper-Threading, but “Arrow Lake-S” has 8, the lack of SMT / HTC does not affect games in general if the core number is so high as 8.
Another interesting feature that can affect gaming performance is the “Arrow Lake-S” cache subsystem. and the 8 P-cores share 36 MB of L3 cache with the four “Skymont” E-core clusters. Thread Director tends not to schedule game workloads on the E-cores unless there are specific game optimizations that use them (for example: for handling game physics, audio DSPs, network stack, etc.).
Intel has promised a big IPC jump for the “Skymont” E-cores over the current “Gracemont”, with the company claiming an IPC similar to that of the “Raptor Lake” P-core. ” increase cores, almost as high as “Raptor Cove” P-cores do, even in this top Core Ultra 9 SKU, the highest E-core increase frequency is 4.60 GHz medium memory to intensity in the calculation His IPC; “Skymont” cores are grouped in groups of four cores and share a 4 MB L2 cache on “Arrow Lake-S”.
Overall, the Core Ultra 9 “Arrow Lake-S” part at these frequencies seems to be competing for AMD’s top gaming performance crown, which it has held for 16 months (since the Ryzen 7 7800X3D to be launched in April 2023). the boaster sells the fastest game processor.
