Intel provides a comprehensive classification for the hardware world Alder Lake At the chip manufacturer’s Construction Day 2021However, Intel did not touch on the topic of the integrated graphics that will accompany Alder Lake.points detective Komachi_Tosaka Smelled a New core boot patch This gives us a little understanding of the iGPU in the mobile Alder Lake chip.
It is worth noting that Alder Lake-M is not the best-performing mobile chip in Intel’s product line.A sort of Previous coreboot update According to reports, Intel may divide mobile Alder Lake into four categories. Alder Lake-M is located at the bottom of the stack and has a 9W TDP. The maximum configuration has two performance (Golden Cove) cores and eight efficiency (Gracemont) cores.
For Alder Lake, Intel ported Tiger Lake’s Gen12 Xe LP graphics engine to the new Intel 7 process. According to the latest code in coreboot, Intel may only insist on using GT1 units for desktop Alder Lake-S processors. The GT1 solution has 32 execution units (EU) and is now called a vector engine.
Alder Lake-MHowever, depending on the processor model, up to three different iGPU solutions can be used. The new coreboot references GT1, GT2 and GT3 units. We already know that GT1 is equipped with 32 EUs, which means that GT2 and GT3 units should be equipped with 96 EUs. The reason why desktop Alder Lake processors are only equipped with GT1 units is that consumers may pair the chip with a discrete graphics card.
Mentioned in coreboot that the GT3 engine may mark the return of Intel Iris graphics, which is basically a high-end version of ordinary high-definition graphics. However, this is different from the Iris Pro or Iris Plus variants. Remember, Intel has historically referred to Iris Pro and Iris Plus graphics cards as GT3e nicknames.
Intel will launch Alder Lake in the fall of 2021. Despite this, the chip manufacturer did not specify whether to release the desktop chip first and then the mobile version of the chip, or whether to release both at the same time. We may hear more about heterogeneous processors at Intel’s innovation event held by Intel from October 27th to 28th.
