We keep talking about the Radeon RX 480 with details as some of the retail Radeon RX 480 4Gb reference graphics cards are equipped with 8 GB memory chips, which are fully functional by simply flashing with the BIOS. On the other side, it has also been confirmed that on the box of these graphics cards they applied a sticker just above where it indicates that it is an 8Gb model, so now we know that if you want to save some money you should look for these models.

Without changing the subject, TechPowerUp, using the application ATI Flash  plus the original BIOS of 8Gb Model easily managed to flash a 4Gb memory model to 8 GB. In performance tests, even the 4GB models with flash bios beating 8Gb press sample version with 0.1 FPS. Obviously they tested the graphics card with a game at 4k resolution without any problem.

Sapphire Listed AMD Radeon RX 490 8Gb GDDR5 On Official Website

On the other hand, from the website of Sapphire we get information on all Radeon RX 400 graphics cards manufactured by company and we have noticed that they have already listed Radeon RX 490 on their website. But the striking thing is the use of GDDR5 memory and not HBM2 memory. So we have to wait to confirm the type of memory that will be used.
