In an odd play of events last year, Intel announced that it is partnering with AMD to make APUs, which will incorporate AMD Vega graphics. While there hasn't been an official announcement yet, a new processor was earlier listed on Intel’s Indian website on the overclocking Intel processors page.
The newest member is named Intel Core i7- 8809G and apparently using two GPUs. One is the HD 630, which is currently what Intel’s Kaby Lake line of processors use (7th gen) and then there is the Radeon RX Vega M GH graphics. The CPU itself is a four core and 8 thread part with a base clock speed of 3.1 GHz, offering 8MBs of cache and Target Package TDP of 100W. The APU is also suggested to support dual-channel RAM of DDR4-2400M.
After being reported by Anandtech, the page has been corrected since. However, this does leave us with enough information to speculate with. First of all, it is worth noting that the 8809G has “G” as a Suffix which points towards it being an all-new line, with on-board discrete graphics denoted by G. The other thing which catches the attention is that the Kaby Lake refresh brings two more additional cores to the Core i7 lineup. However, the 8809G features only four cores, which may imply that at its core it may have more in common with the outgoing 7th gen Core i7. Anandtech also notes that the Kaby Lake Refresh (8th gen) supports DDR4-2666 on its Intel Core i7 parts, but the 8809G is only listed to support DDR4-2400M, which was the norm for 7th gen Intel processors.
At the initial announcement, it was mentioned that the new line of APU will be a replacement for Intel’s ‘H’ line of CPUs, which are generally used by gaming laptops. However, since the new processors were listed among the desktop grade K and X series CPUs, it is a possibility that the new G series APU might be a desktop-grade socketable part. This would imply that Intel may introduce yet another motherboard to host this new beast. The higher TDP of 100W also means that Intel would be introducing an all-new power delivery method for the CPU.
There are more possible explanations, which lead to a lot more questions. However, it is likely that Intel might drop some details at CES next week.
