AMD Radeon HD 6850/6870 Graphics Cards Review
Posted on by Thomas De Maesschalck
AMD Radeon HD 6870 1024MB performs similarly to or a bit slower than GeForce GTX 470. However, it also consumes less power, meaning that it's cooler and quieter. Five interfaces are also a plus. If Radeon HD 6870 is cheaper than GeForce GTX 470, it will sell well.
