Intel has unwittingly published details of an unannounced CPU with AMD Radeon RX Vega images integrated directly on the chip package. In November 2017, Intel and AMD sent the PC enthusiast community into a frenzy with an unparalleled joint announcement that the two rivals are collaborating to launch one or more these goods.
That now seems to be spot on, using a premature listing of the Intel Core i7-8890G appearing on a page comparing the overclocking features of different high-end CPUs on Intel’s India site. It had been spotted by Anandtech and verified by Gadgets 360, but has since been eliminated. According to the listing, the new CPU will feature a ‘Radeon RX Vega M GH GPU’ along with Intel’s own integrated HD Graphics 630 GPU. This confirms the Radeon GPU is essentially a discrete GPU that shares the physiological CPU bundle, but isn’t portion of the true CPU die in precisely the exact same manner that integrated GPUs are. Intel will probably find a way to balance loads so that the Radeon GPU can be shut down completely when not needed, to save electricity and reduce heat output.
The supposed Core i7-8809G appears like it will be a quad-core chip with Hyper-Threading for eight powerful threads, with a clock speed of 3.1Ghz. It isn’t known whether that is a base clock speed or maximum turbo rate, but it is more likely to be the prior dependent on the comparison to other CPUs. It’s an 8MB cache and a 100W TDP. The listing is part of a table which includes all Intel’s current-gen unlocked desktop CPUs in addition to the 7th Gen X-series lineup, all which are overclockable. Intel was expected to target the high-end laptop segment with this launch, but the 100W TDP raises concerns of thermal control in a laptop form factor.
The fact that this really is a quad core part, plus the Intel HD Graphics 630 name (as opposed to Intel UHD Graphics 630) point to Intel’s Kaby Lake or Kaby Lake Refresh architectures because the cornerstone of the new chip, rather than the newer Coffee Lake. Anandtech references a codename ‘Kaby-G’, which will be further evidence of the CPU’s provenance. No specifications concerning the GPU itself have been revealed, like the number of cores or amount of RAM, though it makes sense that AMD will be harnessing its own HBM2 memory technology. Expected functionality is therefore completely unknown.
For AMD, the GPU is a semi-custom design just like the ones it supplies to the manufacturers of various gaming consoles. We know that Vega about the desktop computer runs hot and draws a whole lot of power, so it’ll be interesting to see how the architecture works on this degree.
Shortly after the announcement of this new joint effort between Intel and AMD, Raja Koduri, the former Chief Architect of AMD’s Radeon Technologies Group who oversaw the development of Vega, declared that he was jumping boat and taking a new role at Intel. He is now the Senior Vice President of a newly formed branch within Intel called the Core and Visual Computing Group.
