Panther Lake (microprocessor)
Intel microprocessor, to be released in 2025 From Wikipedia, the free encyclopedia
Remove ads
Panther Lake is a codename for Core Ultra Series 3 processors developed by Intel. Panther Lake processors will support PCIe 5.0. Thunderbolt 5 will be available for desktop processors. DDR5 will be JEDEC standard.[1] The first Panther Lake processors are expected to launch in H2 2025 with mass production in 2026.[2] LGA 1851 socket longevity planned until 2026.

Design and development
Summarize
Perspective
Intel is looking towards Panther Lake production in house rather than using TSMC. Intel is also developing Nova Lake for in-house production. TSMC does have second source capabilities which can complement Intel's own production capacity.[3]
Earlier, Intel was considering 20A but settled on 18A[4] as the D1X Hillsboro, Oregon fab overhaul neared completion. All of Intel's plants have adopted 300 mm wafer in Hillsboro and most of the industry has also moved to 300 mm wafers. Intel is still worried about Cannon Lake and Ice Lake. The Raptor Lake processors, Meteor Lake and Arrow Lake marked a gradual turnaround. Intel is developing 14A which intended to keep the company competitive. Meteor Lake introduced chiplets.[5]
The new Cougar Cove performance core will offer slightly better performance than Meteor Lake. The Skymont efficient cores are also likely to be redesigned. Intel 18A is using a RibbonFET design to reduce leakage. Unlike FinFETs, both the width and the number of the sheets can be varied to adjust drive strength or the amount of current the transistor can drive at a given voltage. The sheets often vary from 8 to 50 nanometers in width. The width of the nanosheets is known as Weff, or effective width.[6]
The PowerVia[7] backside power delivery network allows for better energy efficiency. Intel believes it will deliver about 6% performance gain.[8]
Description
Panther Lake will be Intel's Core Ultra Series 300 CPUs, with updated Cougar Cove performance cores and revised Darkmont E-cores, too. Intel's 18A process, however, is where Intel hopes to right the ship, regain its manufacturing leadership, as well as handle the bulk of the chip's production. It makes sense, then, that Intel is going to push Panther Lake as hard as it can.[1]
The Core 300H is now known to be designed near 55 W of power which will be the entry level.[citation needed]
(P+E+Xe) 4+8+4, 4+8+12 and 4+0+4 are some models being developed.[citation needed]
NPU
Intel is developing AI features. Intel is expected to be offering a 5th gen NPU design to help with Windows Copilot and Google Chrome etc.[9] Mobile lag behind desktop processors so it is not clear if a NPU will be added to the U series processors.[10]
The first gen NPU came out in 2018, gen 2 in 2021, gen 3 in 2023, gen 4 in 2024 and with Panther Lake Intel has the 5th gen. Nvidia has had AI features since the GeForce 20 series. AMD has XDNA and XDNA2 in competition with Intel and Nvidia.[citation needed]
Microsoft Copilot[11] is designed for a machine capable of 40 TOPS. Modern CPU chiplet designs may be able to overcome the thermal power limits by moving L3 off die.[citation needed]
GPU
The Intel Arc Xe3 GPU, codenamed Celestial which is seen already in the discrete ARC B580. It's expected to be released in late 2025, integrated into the Panther Lake CPUs. Intel is known to be working on the drivers for Xe3 for next generation laptops. Intel drivers are rather basic miniport drivers like AMD and NVIDIA both also use with Windows 11 driver specifications. Intel has worked hard on DX drivers which are needed for gaming and other applications.[12]
Design
Panther Lake features up to 16 cores (performance cores plus efficiency cores) and no SMT. H series tend to have half as many cores and U series the design is 9–15 W. The chiplet design may allow Intel to offer additional L3/L4 cache memory.[citation needed]
