An Intel graphics {hardware} engineer has revealed the codename of a brand new Intel built-in graphics unit and CPU structure, often known as Panther Lake, in his job description on LinkedIn. The engineer has since pulled the knowledge, however Tom’s {Hardware} seen and screenshotted the blurb whereas it was reside.
Nothing is understood about this mysterious structure, however we all know the iGP will run on a model of Intel’s Xe3 Celestial GPU structure. In response to the LinkedIn profile Panther Lake and its related iGP are set to be introduced throughout Intel Structure Day 22. If true, we should always know some official architectural and energy specs by then.
Primarily based on the small print given, Panther Lake and its related built-in graphics processor shall be produced a number of years down the street after Meteor Lake, Arrow Lake, and Lunar Lake are launched. Lunar Lake – Intel’s furthest CPU structure of the three, is ready to reach someday in 2024. So Panther Lake will most likely arrive someplace round 2024 or 2025.
Primarily based on this timeline, we guess Panther Lake (as a CPU structure) will most likely make the most of Intel’s 20A manufacturing course of that’s set to reach within the second half of 2024. 20A is a serious milestone for Intel and is the primary node to enter the angstrom period, the place the bodily options of a chip can not be precisely measured in nanometers. As a substitute, the chips shall be measured in angstroms – or one ten-billionth of a meter.
This doesn’t imply that the person transistors are assured to be beneath a single nanometer in dimension, simply that the bodily options can not be measured on the nanometer scale. Alongside this new breakthrough, 20A will function a model new transistor structure known as RibbonFET – a successor to EUV, and a brand new transistor wiring expertise known as the PowerVia interconnect.
Intel does not specify efficiency or wattage good points, however it’s secure to imagine that 20A will function an infinite efficiency benefit over Alder Lake and Raptor Lake. For reference, Intel 4 – which shall be used on Meteor Lake guarantees a 20% efficiency per watt acquire, over Alder/Raptor Lake. Whereas Intel 3 – will present an 18% efficiency per watt enchancment over Intel 4.
If this identical pattern follows, Intel 20A will most likely be at the least one other 15% extra environment friendly than Intel 3, making Panther Lake probably 50% extra environment friendly than Alder Lake or Raptor Lake.
Panther Lake iGP
Just like the CPU facet of the equation, we all know mainly nothing about Intel’s Celestial GPU structure. Celestial shall be Intel’s third era GPU following Arc Alchemist and Battlemage, working underneath the Xe3 nomenclature.
Nevertheless, one truth that’s made clear by the LinkedIn description is that Celestial won’t solely be utilized in discrete GPUs however will even be utilized in Intel’s built-in graphics options. This is not stunning, contemplating Intel does this at this time with its present GPU architectures, however it’s good to know that Intel is assured sufficient in its new discrete GPU architectures to proceed utilizing them in its built-in graphics options as nicely.
