Of the few remaining Video Game Brand Battles, the AMD vs. Nvidia fight might be my favorite. The two graphics companies often take small swipes at each other, and usually with less restraint than console or game manufacturers.

The latest shot comes from AMD, in an update they posted to Facebook (via NeoGAF):

970 minutes might seem like an unusually long amount of time for a promotion like this, but that's the joke. The post is a riff on the recent discovery by posters on the Nvidia and Guru3D forums (well-summarized on reddit) that Nvidia's widely praised GTX 970 graphics card, which boasts a meaty 4GB of memory, encounters trouble when it uses more than 3.5GB of that memory.


PC Gamer has posted a technical breakdown of the issue and Nvidia's various responses, which get into hardware differences between the 970 and Nvidia's more expensive, more powerful top-end card, the GTX 980. The short version is: The 970 is still a generally speedy card, but due to limitations in how it transfers data, it doesn't use its full memory bandwidth to the same extent as the 980. Because of that, it's harder to argue that the 970 is truly a "4GB card" in the way that most PC gamers assumed it was based on the card's marketing and packaging.

The thing I like about this kind of sniping is how it inevitably comes back to bite the snipe-rs in the ass. It seems like only a matter of time until AMD screws up and Nvidia comes in, all smiles, to score some cheap points of their own. For now, though, AMD's drawn the most recent blood.
