4GB of RAM is standard equipment for the latest single-GPU flagships from AMD and Nvidia. Cards with twice as much memory are reportedly on the way, though. According to Sweclockers, AMD will answer the GeForce GTX 980 with an 8GB version of the Radeon R9 290X. That variant is due on November 6, the site says, putting it less than a week away.
As one might expect, the larger memory pool is expected to be limited to higher-end products with hot-clocked GPUs and custom coolers. VideoCardz has already posted a picture of one example, an 8GB version of MSI's R9 290X Gaming. Contrary to Sweclockers' claim that 8GB models will be restricted to certain manufacturers, VideoCardz indicates that all Radeon partners will be able to offer more memory.
Citing an Nvidia roadmap, VideoCardz goes on to say that the green team is prepping an 8GB version of the GeForce GTX 980. That card is reportedly scheduled for November, though a story at Hermitage Akihabara lists a November-December timeframe. Either way, the top GeForce looks set to match its Radeon counterpart gigabyte for gigabyte.
With the latest consoles sporting 8GB of RAM (albeit shared between the CPU and GPU) and 4K monitors picking up steam in the PC sphere, loading additional memory onto high-end cards seems like a good idea. It certainly makes more sense than the time-honored tactic of equipping lower-end cards with ridiculous amounts of RAM.
