AMD Radeon HD 7950 Boost vs. Nvidia GeForce GTX 660 Ti: frametimes review

They cost about the same, but which one is the fastest?

By ,


Introduction

Last week we introduced you to the concept of of frametime tests, a more accurate way of measuring graphics card performance in video games. We already tested the AMD Radeon HD 7970 GHz Edition and the Nvidia GeForce GTX 680 in this new way, which brought us to a different conclusion than the one based purely on frames per second performance. Today we are looking at the AMD Radeon HD 7950 Boost versus the Nvidia GeForce GTX 660 Ti.

These two graphics cards are in the same price segment, around $300, and are significantly more affordable than the two cards from our last review. Click here to read our original review of the Radeon HD 7950 Boost. The Nvidia GeForce GTX 660 Ti is the most affordable Nvidia card based on the GK104 GPU, the same chip used in the GTX 680 and 670.

Benchmarks

Our graphics card test platform consists of an Intel Core i7 3960X, an ASUS P7X79 Pro motherboard, 16 GB DDR3-1600 memory, a Samsung Spinpoint F1 1TB hard disk, a Cooler Master Silent Pro Gold 1200W power supply, and Windows 7 x64.

For the frametime test we focused on the most popular resolution, and that's still Full HD for most people. The five games we tested are: Assassin's Creed III, Battlefield 3, Far Cry 3, Hitman: Absolution and Max Payne 3. We tested each one with Normal/Medium settings and also with the highest settings. With the highest settings we also enable 4X AA when possible.

On the following pages we first display the chart with the average frames per second, and then the chart with the 99th percentile of the frametimes. The third chart has the render times of the first 1,500 frames of each of the benchmarks. We don't chart the entire benchmark, because there would be too much clutter.

The AMD Radeon HD 7950 Boost was tested with Catalyst driver version 13.2 beta, and for the Nvidia card we used GeForce driver versie 310.90.
