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.
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.
| ||Graphics Card Test System|
|Processors||Intel Core i7-4960X – Six-Core @ 4.50GHz|
|Motherboard||ASUS P9X79-E WS|
|Memory||Kingston HyperX Beast 32GB (4x8GB) – DDR3-2133 11-12-11|
|Graphics||AMD Radeon R9 280X 3GB (Catalyst 13.11)|
AMD Radeon R9 270X 2GB (Catalyst 13.11)
NVIDIA GeForce GTX 760 3GB (GeForce 331.40)
NVIDIA GeForce GTX 660 2GB (GeForce 331.40)
|Storage||Kingston HyperX 240GB SSD|
|Power Supply||Cooler Master Silent Pro Hybrid 1300W|
|Chassis||Cooler Master Storm Trooper Full-Tower|
|Cooling||Thermaltake WATER3.0 Extreme Liquid Cooler|
|Displays||ASUS PB278Q 27″ 2560×1440|
Dell P2210H 22″ 1920×1080 x 3
|Et cetera||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:
- Windows Defender
- Windows Firewall
- Windows Search
- Windows Update
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:
(AMD) – BioShock Infinite
(AMD) – Sleeping Dogs
(AMD) – Crysis 3
(NVIDIA) – Battlefield 3
(NVIDIA) – Metro: Last Light
(NVIDIA) – Splinter Cell Blacklist
(Neutral) – Total War: SHOGUN 2
(Neutral) – GRID 2
With that, let’s move on to a quick look at the game settings we use in our testing:
Metro Last Light
Splinter Cell Blacklist
Total War: SHOGUN 2
