WIFI 6 and new iGPU


WIFI 6, also known as Wireless AX, had been on its way to replace Wireless AC for a while now. The new technology will be mostly integrated into the SoC, and will offer over 1Gbit/s.


Intel is a leader in Wireless technologies, especially WIFI, and here we see that on the 160MHz band we can expect upwards of 1.7Gbps, which is on par with Wireless AC 160MHz products, but in this case we might actually see these speeds as more than theoretical.


While many might assume that the new WIFI controller is integrated into the SoC, some of it is not. By utilizing Intel's CNVI technology, Intel integrated the digital MAC portion of the controller, while the analog section is located outside, like most PHY WIFI devices on current Intel products.


Infrastructure is also very important, and in this case, Intel has worked with vendors to ensure many routers and access points support the new Wireless AX technology.


Graphics have also been bumped up a notch, with new HEVC encoders that support up to 4K 60FPS at 4:4:4 and 8K 30FPS at up to 4:2:0.


Supporting up to three displays, the new iGPU will support up to DisplayPort 1.4 and output 5K 60FPS or 4K 120FPS, so we might see much better displays in new notebooks.


The internal iGPU microarchitecture has also been improved and supports up to 64 execution units and up to 2.25 teraflops.


The rasterizer engine has also been improved and is capable of 16 pixels per clock.


The end result will be a notebook as thin as an Ultrabook, but capable of actually gaming at 1080. The new system also supports VESA's adaptive sync specification. Intel has also revamped its gaming software to help gamers improve their experience.


Adaptive sync is much like the other display synchronization technologies, where you don't see tearing, so it improves the gaming experience.


Here we see Intel's new iGPU in action, and while these are self-reported numbers, we do expect some major improvements.


To summarize, we get DisplayPort 1.4, HDMI 2.0b, HDR10, 8K, and new software to help improve the gaming and visual experience of the new SoC and resulting notebooks.


Intel has also been reaching out to the gaming community and is now working on fully supporting the Linux stack.
