AMD Radeon HD 7790 CrossFire

Introduction



The most interesting feature of sub-$200 graphics cards is their ability to transform from mid-range single-card solutions into high-end dual-card ones through the use of multi-GPU technologies like AMD CrossFire and NVIDIA SLI. With dual-GPU capable motherboards not being particularly expensive and with guaranteed support for AMD CrossFire on both Intel and AMD platform motherboards, the prospect of buying a $150 Radeon HD 7790 graphics card now to keep up with the latest games before dropping in another $150 later (subject to future price-cuts) for a solution that performs on-par with some of today's high-end solutions, instead of spending $300 in the future, seems like a sensible thing to do if you can live with the pitfalls inherent to multi-GPU solutions. The bigger question, though, is exactly how well the Radeon HD 7790 scales in CrossFire with today's available titles, to give you an idea of what to expect.

Before you proceed, make sure you've read our single-card reviews:Both of the above cards feature custom designs and ship with factory-overclocked speeds. In this review, we clocked both cards down to AMD reference frequencies of 1.00 GHz core and 6.00 GHz memory. The setup is put through our usual battery of graphics tests.
