We took AMD’s $300 Radeon R9 280X for a spin last week and were left quite impressed overall with the results, versus the GTX 760. Will we get the same sort of reaction with the company’s Radeon R9 270X? With the help of NVIDIA’s ~$175 GeForce GTX 660, we’re going to find that out.
Test System & Methodology
At Techgage, we strive to make sure our results are as accurate as possible. Our testing is rigorous and time-consuming, but we feel the effort is worth it. In an attempt to leave no question unanswered, this page contains not only our test-bed specifications, but also a detailed look at how we conduct our testing.
The below table lists our testing machine’s hardware, which remains unchanged throughout all GPU testing, minus the GPU. Each card used for comparison is also listed here, along with the driver version used.
ASUS PB278Q 27″ 2560×1440 Dell P2210H 22″ 1920×1080 x 3
Windows 7 Professional 64-bit
When preparing our test-beds for any type of performance testing, we follow these guidelines:
No power-saving options are enabled in the motherboard’s BIOS.
No virus scanner or firewall is installed.
The OS is kept clean; no scrap files are left in between runs.
Machine has proper airflow and the room temperature is 80°F (27°C) or less.
To aid with the goal of keeping accurate and repeatable results, we alter certain services in Windows 7 from starting up at boot. This is due to the fact that these services have the tendency to start up in the background without notice, potentially causing inaccurate test results. For example, disabling “Windows Search” turns off the OS’ indexing which can at times utilize the hard drive and memory more than we’d like.
The services we disable are:
For further fine-tuning, we also use Windows’ “Classic” desktop theme, which gets rid of the transparency that can sometimes utilize a GPU in the background.
Sometimes, either AMD or NVIDIA will work with a game studio to help their development process along. As history has proven, this often results in a game that is tuned better for one vendor over the other, although sometimes the tides can change over time, resulting in the opposite vendor offering the better experience.
One of our goals is to provide as neutral a benchmarking suite as possible, so while it’s impossible to avoid games sponsored by either of these companies, we can at least make an effort to achieve a blended list. As it stands, our current game list and their partners are:
