HBM to Revolutionize Video Cards, Starting with AMD's Radeon R9 390X

Now We Know About HBM, Let's Talk the Radeon R9 390X


Now that we've had a quick dip into the HBM pool, we need to remind you: this is the first generation of HBM. HBM2 will double the bandwidth up to over 1.2TB/sec, the first time in history that we've had GPU memory - or any consumer memory - with over 1TB/sec of bandwidth.



We've been posting a considerable amount of rumors, reports and insider information about the Radeon R9 390X, which will be the first video card to use HBM. AMD has been working with SK Hynix and many other companies to get this off the ground, and the fruits of that labor will be the Fiji XT-based Radeon R9 390X.


What we do know so far, are just from rumors. The Radeon R9 390X should have between 4-8GB of HBM-based VRAM, and arrive in two versions: one with a normal air cooler, while another will arrive with a hybrid water cooling system.


Furthering the rumors is talk of two versions of the Radeon R9 390X, one with GDDR5 and another with HBM. Then we have the rumors of the rebrands, which will rebrand the Hawaii XT-based Radeon R9 390X as a card in the upcoming Radeon R9 300 series.
