Intel has unwittingly published details of an unannounced CPU with AMD Radeon RX Vega graphics integrated right on the chip package. In November 2017, Intel and AMD delivered the PC enthusiast community into a frenzy with an unparalleled joint statement that the two rivals are collaborating to launch one or more such goods.
That now appears to be put on, with a ancient listing of those 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 include a ‘Radeon RX Vega M GH GPU’ as well as Intel’s own integrated HD Graphics 630 GPU. This affirms that the Radeon GPU is basically a discrete GPU that stocks the physical CPU package, but is not part of the true CPU expire in precisely the same manner that integrated GPUs are. Intel will likely find a way to balance loads so the Radeon GPU may be shut down entirely if not needed, to save power and reduce heat output.
The supposed Core i7-8809G looks like it will be a quad-core chip with Hyper-Threading for eight powerful threads, using a clock speed of 3.1Ghz. It is not known whether that is a foundation clock rate or maximum turbo rate, but it is more likely to be the former dependent on the comparison to other CPUs. It has an 8MB cache and a 100W TDP. The listing is part of a table which includes all of Intel’s current-gen unlocked desktop CPUs as well as the 7th Gen X-series lineup, all which can be overclockable. Intel was expected to aim the high-end laptop section with this launch, but the 100W TDP raises questions of thermal control in a laptop form element.
The simple fact that this really is a quad-core part, plus the Intel HD Graphics 630 title (as opposed to Intel UHD Graphics 630) point to Intel’s Kaby Lake or Kaby Lake Refresh architectures as the cornerstone of this new processor, rather than the newer Coffee Lake. Anandtech references a codename ‘Kaby-G’, which will be further proof of the CPU’s provenance. No specifications about the GPU itself have been revealed, like the number of cores or amount of RAM, though it stands to reason that AMD will be harnessing its HBM2 memory technology. Expected functionality is therefore completely unknown.
For AMD, the GPU is a semi-custom design exactly like those it provides to the producers of various gaming consoles. We know that Vega about the desktop computer runs hot and draws a whole lot of electricity, so it’ll be interesting to determine how the architecture performs on this level.
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 he was jumping boat and taking up a new role in Intel. He’s currently the Senior Vice President of a newly formed branch within Intel called the Core and Visual Computing Group.
