AMD Radeon RX 490 was rumored to have hinted its release soon. A Norwegian site was seen listing a possible AMD Radeon RX 490 model.
AMD Radeon RX 490 Release: Where The Hint Started
In the Norwegian website Prisguide, upon checking, the news is likely nothing at all. It is nothing but hype made by tech sites. This is another product of speculations about the listing of the unreleased GPU flooding the web for months. It is not difficult to expect crafty price comparison site wanting to get a product page up online before the competition. They have used a stock image of an RX 480 to illustrate the page and have not programmed any useful specs either.
AMD Radeon RX 490 Release: Other Clues
Interestingly, though, Hot Hardware posted an "Ashes Of The Singularity" AOTS benchmarking database lately. AMD is noted to have been using AOTS for testing they issue for new cards. The listing does not describe the GPU at all but merely gave device ID of 687F:C1. The ID affirms that it is an unreleased card. It does look a lot like an AMD ID -- the RX 480 is patent as 67DF:C7. The main section must be the ID of the GPU itself with the next being the revision number. The C1 part might designate the times the card has undergone revision, so possibly not that close to release.
For its actual performance, the figures place the card on the same level as the GTX 1070 and GTX 1080. The AOTS benchmark though is relatively CPU dependent, so the variety of chip has a lot of influence over the final score. This, in turn, means this does not tell us a lot about the performance of this unreleased and unnamed GPU.
AMD Radeon RX 490 Release Happening Very Soon?
Because the benchmarks have just gone online many are expecting the announcement of an RX 490 at AMD's New Horizon Zen preview event on December 13. If the CPU was behind as unlisted then it is agreeable. The user, however, ran the benchmark on an old Intel octo-core, not a new Zen CPU. If this is new AMD graphics silicon, it is not expected to appear that soon.
