Late March AMD introduced the Radeon HD 7790, and a week later Nvidia answered with the GeForce GTX 650 Ti Boost. We compared to the two cards, but it wasn't really a fair comparison since the first Radeon HD 7790 cards came with only 1 GB of video memory, while the GeForce GTX 650 Ti Boost has 2 GB. That influenced both price and performance.
Sapphire now sent us a Radeon HD 7790 with 2GB of video RAM, the Sapphire Radeon HD 7790 OC 2GB. With an average price of £139 or €164 it costs almost exactly the same as the Nvidia GeForce GTX 650 Ti Boost cards with 2 GB. It's a much fairer comparison, in other words. Read on to find out which card gives you the most value for your money.
In this review we will focus on the performance of the Radeon HD 7790 and Nvidia GeForce GTX 650 Ti Boost and how they compare, along with the specific test results of Sapphire's card. For an in-depth review on the underlying hardware, read the individual reviews of the Radeon HD 7790 and the GeForce GTX 650 Ti Boost.
For the GPU benchmarks we set the Sapphire Radeon HD 7790 2GB at the standard clock frequencies of the Radeon HD 7790 2GB: 1000 MHz for the GPU and 1500 MHz for the memory.
We tested the graphics cards on our graphics card testing platform, which consists of an Intel Core i7 3960X, 16 GB DDR3-1600 memory, a Samsung Spinpoint F1 1TB hard disk, a Cooler Master Silent Pro Gold 1200W PSU and Windows 7 x64.
We tested the card in 1920x1080 Full HD resolution. We tested games on "normal" settings and also on the best possible settings (highest/ extreme/ ultra). We enabled 4x AA for the test on the highest settings, when possible. The GeForce GTX 650 Ti Boost is not powerful enough for three monitors, so we didn't include the scores in the article, but you can find them on the page with all the specs and scores.
