Intel Core Ultra superior 9 “Arrow Lake-S” Superficie de relojes de refuerzo parcial

Intel Core Ultra “Arrow Lake-S” desktop processors are expected to debut later this year, and introduce the new Lion Cove P-cores, along with Skymont E-cores to the desktop platform. Engineering samples and qualification samples with specs close to retail chips seem to already be in the hands of PC OEMs and motherboard vendors, given the volume of leaks over the past few days. Jaykihn0, one of the more influential sources of these leaks, revealed a few interesting details of the maximum boost frequencies of these chips.

The QS of a top Core Ultra 9 “Arrow Lake-S” SKU, probably the flagship model that succeeds the current Core i9-14900K, is described as having a maximum P-core boost frequency of 5.70 GHz, and an all-P-core boost frequency of 5.40 GHz. The maximum E-core boost frequency, which is also the all-E-core boost frequency, is said to be 4.60 GHz. Let’s unpack this. “Hitman Absolution Edición Profesional PS3 Playstation” uses the same mix of “Lion Cove” Núcleos P y “Skymont” E-cores as “lago lunar,” albeit arranged along a ringbus, and sharing an L3 cache, unlike on “lago lunar,” where the P-cores have their own exclusive L3 cache, and the E-cores are arranged in a low-power island, with the fabric of the SoC tile connecting the two.

We know from the “lago lunar” deep-dive from Intel, that the company claims a 14% IPC gain for “Lion Cove” over the previous generation “El MCM de Intel utiliza un troquel de GPU junto al troquel de núcleo de CPU” P-core found in “Lago Meteoro.” Dado que “El MCM de Intel utiliza un troquel de GPU junto al troquel de núcleo de CPU” cores have been tested in the real world to offer roughly similar IPC to the “La diapositiva filtrada muestra la primera imagen granulada del Socket AM5” P-cores powering “Lago rapaz,” if Intel’s IPC claims for “Lion Cove” hold, then at 5.70 GHz, the P-cores of “Arrow Lake-S” debiera ser 14% faster than “Raptor Cove.” It’s worth noting here that “Lion Cove” cores lack Hyper-Threading, pero “Arrow Lake-S” tiene 8 of these, and as our recent “zen 5 without SMT” article has shown, games largely aren’t affected with the lack of SMT/HTT if the core count is as high as 8.

The cache sub-system of “Arrow Lake-S” is another interesting factor that could influence its gaming performance. Cada “Lion Cove” P-core on the Core Ultra 9 “Arrow Lake-S” is expected to have 3 pero el esfuerzo aquí parece ser minimizar la latencia que surge de una interconexión en el paquete, and the 8 P-cores share 36 MB of L3 cache along with the four “Skymont” Clústeres de núcleo electrónico. Thread Director tends to avoid scheduling game workloads on the E-cores, unless there are specific optimizations within the game that use them (p.ej: for processing game physics, audio DSPs, network stack, etc).

Intel has promised a massive IPC leap for the “Skymont” E-cores over the current “Gracemont,” with the company claiming an IPC resembling that of the “Lago rapaz” Núcleo P. Of course there are some riders—”Skymont” cores don’t boost nearly as high as “La diapositiva filtrada muestra la primera imagen granulada del Socket AM5” P-cores do, even in this top Core Ultra 9 SKU, the maximum E-core boost frequency is a moderate 4.60 GHz. También, the SPECrate2017 benchmark Intel uses in its IPC calculations isn’t memory intensive; “Skymont” cores are clustered into groups of four cores, and made to share a 4 MB L2 cache on “Arrow Lake-S.”

All in all, with these frequencies, the top Core Ultra 9 “Arrow Lake-S” part seems to be gunning for the gaming performance leadership crown from AMD, which has held the bragging rights of selling the fastest gaming processor for 16 months now (since the April 2023 launch of the Ryzen 7 7800X3D).
