The details were found on Chipzilla’s Indian website, within the table of overclockable processors, accompanying the Core i9, Core i7-X and 8th Generation K processors. There in the middle, where no one would notice, is listed the Intel Core i7-8809G, a quad-core processor with two sets of graphics options listed.
The Core i7-8809G has not been formally announced in a press release.
On Intel’s overclocking webpage it as listed as being a quad-core processor with hyperthreading, supporting a 3.1 GHz base frequency. It has an 8 MB L3 cache, a 100W ‘Target’ TDP, and supporting two channels of DDR4-2400. Intel lists both sets of graphics: the integrated graphics (iGPU, or IGP) as 'Intel HD Graphics 630', and the package graphics (pGPU) as ‘Radeon RX Vega M GH Graphics'.
Initially, everyone thought that it was a Coffee Lake-based Core i7 part, but all of them have six cores, while this only has four, which would suggest it is more likely to be Kaby Lake.
The AMD graphics portion of the chip is listed as Radeon RX Vega. It is called the ‘Vega M GH Graphics’, which is fairly undefined at this point. The website does not state exactly how many compute units are in the GPU, so it is unclear if ‘GH’ is going to indicate how powerful it is, or something else.
It is also worth pointing out that all this is listed with desktops and not mobile chips. This means that the processor is aiming for a desktop/socketed motherboard.
