 So in my XFX 5850 unboxing, what I realized is that I didn't really go into enough depth about what are the differences between these two cards. So first let's talk about the physical differences, okay? The most obvious one is the difference in length. So we're going to measure the 5870 from the very edge of the PCI bracket here to the end of the card is 11 and one-eighth of an inch. And then for the 5850, the same measurement is only nine and, oh, just a hair over a half. So it's about nine and, you know, five-eighths of an inch. Okay, but something that you have to factor in is that you're going to need almost another inch or so, maybe three-quarters of an inch, for the PCI Express connector. So it actually is more like, more like ten and a half. So you're only looking at about a one-inch difference between these two cards when they're installed in your case. Now they both support DirectX 11 and they both support iFinity with up to three monitors, one display port, and two other digital displays. Now in terms of the overall spec, I'm going to cheat a little bit here and I'm going to look at the chart on hardware Canucks because it's very, very useful. So the 5870 is clocked at 850 megahertz on the GPU core and the 5850 is clocked at 725. The 5870 has faster memory at 4.8 gigahertz, whereas the 5850 is clocked at 4000, so just four gigahertz. There are a couple other differences. For example, the stream processors are down from 1600 stream processors to 1440, and then you're also a little bit reduced on the ROPs, okay? Or sorry, the texture units, the ROPs are the same. So what that means is that with the 5850, based on all the benchmarks I've seen, I haven't had a chance to test it yet, you're looking at about 10 to 15 percent slower, but at a significant cost reduction. So thank you for checking out my differences between the 5870 and the 5850 video.
