GPU Memory Bandwidth of 1TB/s Could Be Coming Soon

Category: Video Cards
Posted: 05:25PM

The AMD Radeon R9 390X is expected to be one of the first cards to use High Bandwidth Memory, HBM, and has the potential to provide memory bandwidth up to 640GB/s over a 4096-bit memory bus. The first generation of HBM is made by SK Hynix and is capable of bandwidth of 128GB/s per die, with up to four die able to be grouped. The second generation of HBM will be even faster, reaching bandwidth up to 256GB/s per die, giving it the ability to provide 1.28TB/s bandwidth per four core group. For comparison, an NVIDIA GeForce GTX 980 has 224GB/s memory bandwidth. The massive increase in memory bandwidth will help to provide for better performance, especially as higher resolution displays gain popularity.
