| This is a really great test. Thanks much for putting the work in and posting your results for the community! The memory bandwidth results are interesting. I'd expected thunderbolt to be a big bottleneck for doing Resolve work, but if uncompressed HD is around 240MB/sec, 740MB/sec is certainly enough to have a stream going in and a stream coming out. You'd probably feel the hit if you tried to do stereo 4K work, but that's too much to expect out of a game card anyway. Thanks again! -bH On Thu, May 3, 2012 at 8:36 AM, Dave Bittner <dave@pixelworkshop.com> wrote: I was curious about how much a real-world difference it makes, putting a high performance graphics card in a 16 lane slot vs. a four lane slot, and how this information could inform the possibilities of using Thunderbolt for external graphics cards. -- |
