14 DAY TRIAL // Codecs might not matter to you much, but they determine the size of a video file, and also the encoding/decoding speed and efficiency. That's why it helps to know what codecs will be supported by future GPUs: it lets filmmakers and producers know what file types to accommodate.
According to word on the net, the 20 nm Maxwell graphics processing units from NVIDIA will support H.265.
H.265 is one of two potential successors to the H.264. They both promise twice the efficiency, a huge reduction in file size, the works.
H.265 takes 64 x 64 ‘superblocks’ and performs 35 infra-prediction directions to rebuild them, while increasing bit size. VP9 doesn't need the blocks and is open source.
Films encoded with either codec should be available in 4 x 8 or 64 x 32 sizes, among others.
The folks at Fudzilla are the ones who say that NVIDIA's 20nm Maxwell chips will handle H.265. That doesn't necessarily mean VP9 will be left out though.
Alas, it's still unlikely that the GPUs will come out this year. TSMC is having trouble with the manufacturing node after all. It's a real shame, since it's basically forcing NVIDIA (and AMD for that matter) to redesign the next-generation architecture for 32 nm.
