Eventually we're going to see next-generation graphics cards outfitted with GDDR5X memory. It's a process getting to that point, and slowly but surely, things are moving along. To wit, JEDEC ratified the GDDR5X specification back in January of this year, and not even a full month later Micron announced that its GDDR5X program was in "full swing" with sampling to soon follow. Well, that time has come.We just got word straight from Micron that it has indeed started sampling GDDR5X memory to clients. That's a big deal because it's one of the last steps in the rather long process of introducing new... Read more...
We have been hearing about the next iteration of DDR for graphics for the past handful of months, and now, the folks at JEDEC have made it official. Called GDDR5X (the full standard is called JESD232 GDDDR5X SGRAM), this memory is designed to be twice as fast as GDDR5 per clock, boasting total throughput rates of 14Gb/s per pin. With GDDR5, peak bandwidth was 8Gb/s, which required the memory to be run at 2GHz. NVIDIA's current top-end cards peak at 7Gb/s, with clock speeds of 1.75GHz. With GDDR5X, we can see performance of 10Gb/s - 2Gb/s better than the previous max - at 1.25GHz. That's 70%... Read more...
