The big news of late 2017 was Intel's announcement that it would integrate AMD Radeon RX Vega class graphics on a multi-chip module (MCM) with its Kaby Lake-G processor. Aimed at the laptop market, this exclusive product aims to compete with NVIDIA's mid-range offerings. We haven't seen an official confirmation yet, but word on the street is that this product was made at the request of Apple.
However, the Intel chip with Vega graphics is a bit of an admission that the chip giant's own graphics solutions simply aren't powerful enough for today's market. To fix this mess, Intel revitalized its graphics efforts and hired former AMD Radeon guru Raja Koduri as Chief Architect.
Now we learn that Intel's 12th Gen discrete GPU is codenamed "Arctic Sound". This chip will connect to the CPU via Intel's EMIB interconnect, similar to the current Kaby Lake + Vega implementation. Eassa also learned that the 13th Gen discrete GPU is codenamed "Jupiter Sound".
No further details were provided. Intel's Kaby Lake processors feature Gen 9.5 graphics so Arctic Sound and Jupiter Sound shouldn't be expected before the early 2020s. These things take time.
