Intel's Xe discrete GPU project head Raja Koduri recently visited a Samsung Electronics silicon fabrication facility in Korea at the backdrop of the company's major 5 nm EUV announcement. This sparks speculation that Koduri could be exploring Samsung's portfolio of sub-10 nm contract-manufacturing offerings to mass-produce Xe discrete GPUs. Intel's own foundry business is reeling with mounting pressure from the company's main breadwinner, the client and enterprise processor businesses, to get its 10 nm node on the road. Koduri's GPU would need to leverage higher transistor densities than what Intel's 10 nm could offer, given that rival AMD is already implementing 7 nm, and NVIDIA is expected to go sub-10 nm with its future generation of GPUs.

interesting, however just speculation
 
This could benefit both companies

Intel has troubles to this day with 10nm so it is better to offload graphics chip manufacturing to another company. Only TSMC and Samsung can handle what Intel wants. 

well intel sure can't use it own fabs - 10nm is a disaster 35% yield rate
 
they won't have 5nm up in any time - and any fab space they have will be use for battling out the cpu war
 
so yeah using tsmc or samsung is in the works
