HBM, the revolutionary stacked retentivity for graphics has been pictured for this showtime fourth dimension. Coming with AMD Radeon R9 390X and Nvidia Pascal. Aye, it's finally hither folks. The next affiliate in memory technology for computer graphics.

HBM Memory Just as a quick reminder, HBM stands for "Loftier Bandwidth Memory". It's a make new JEDEC memory spec co-adult by SK Hynix and AMD. HBM is fabricated past stacking multiple DRAM cells on-top of each other to make a 3D strucutre. These DRAM cells are then continued vercially with each other through what'southward called Through Silicon VIAs or TSVs. This vertical connection enables the retention to transfer significantly more data per cycle. So while the memory itself is clocked at a significantly lower frequency than GDDR5, information technology can actually be up to nine times faster.

Nosotros've learned that AMD handled the research and development of the memory interface / memory bus for HBM that goes on the host processor such every bit a GPU or APU. AMD also developed the technique past which the HBM cubes are connected to the host chip via an interposer. At present without any further delay let's take a look at the new retention chips.

AMD will be the first company e'er to utilise this new memory technology every bit nosotros take told you exclusively over 6 months ago. And the first generation of HBM will debut with the visitor'southward upcoming flagship graphics carte du jour, the R9 390X. The company will subsequently move to the 2d generation HBM once that applied science becomes available next year. The contempo slide leak which revealed the performance of AMD's Fiji XT also served to confirm the information which nosotros take exclusively brought to you lot over the past and electric current year.

Nvidia has announced that it too volition use HBM for its GPUs. Still unlike AMD, Nvidia will only utilise the second generation of the technology. Which will debut on the dark-green side side by side year with the company'southward promising new Pascal graphics architecture. In fact Pascal will feature 4X the mixed precision functioning, 2X the performance per watt, 2.7X memory capacity & 3X the bandwidth of Maxwell every bit revealed by Nvidia's CEO Jen-Hsun Huang at the latest GTC.

Pascal and AMD'south Arctic Islands GPUs volition be the offset to feature the second generation of HBM. As well as the commencement ever from either company to exist manufactured on an advanced fourteen/16nm FinFET manufacturing process. Just before that happens, we're still waiting for the fabled Fiji to show-upward. In the concurrently we'll have to endure teases of the new monster, because as information technology turns out XFX is excited for the new card besides and decided to tell anybody about it, "secretly"
