Drivers
The latest drivers are always used at the time of testing, but please note reviews undergo a scheduling process. This means a new driver could be released on the day of publication. However, this is unavoidable and disclosing the driver versions used is the most transparent way of informing the reader about current performance levels.
Games
When reviewing affordable graphics cards which struggle at the highest presets, the visual settings are reduced accordingly to provide a clearer indication of performance. Then, products within this category are benchmarked against each other at 1920×1080 since anything higher yields very poor frame rates. In every case apart from Ashes of the Singularity, the visual details are configured to high which appears to be strenuous enough while making 60 frames-per-second an achievable target on certain models.
Please note, Ashes of the Singularity is deployed with the Standard preset and any other key details are disclosed on each chart’s header. While I could have added higher-end options like the GTX 970 all the way up to the GTX 1080, it didn’t seem appropriate given the price point of lower-end cards. Also, all games are benchmarked with FXAA enabled unless the specified preset overrides this.
Since I’ve taken the helm as graphics card reviewer, I wanted to put fairness at the heart of each article and ensure there’s a good balance between DirectX 11 and DirectX 12 games. This allows me to properly analyse each graphics card as focussing on sponsored titles from a particular vendor will always result in an inaccurate picture. Unfortunately, popular monitoring software like FRAPS cannot display the frame-rate in real time and poses a problem when observing performance numbers. Thankfully, it’s still possible to use FRAPS’s Min/Avg/Max function which I’ve found offers the most reliable monitoring compared to other methods. If you have any suggestions to aid the benchmarking process, please let me know so I can constantly improve the procedure.

Synthetic Benchmarks
During our testing, we use a range of readily available synthetic benchmarking tools which are free to download from the respective websites. We do this so the readers can download and compared to our results. Download links are contained within the “Software” subheading.
Noise
Everyone has their own reasonable noise level when it comes to comes to components in a computer. Some can handle all fans at 100% load to keep temperatures down, some want a completely silent computer. To properly gauge the noise output of a graphics card, we position a Precision Gold N05CC Decibel meter from two metres away and take an average reading.
Power Consumption
With electricity becoming increasingly expensive across most parts of the world the need for computer components to become power efficient has never been more relevant. Graphics cards are often the most power-hungry components of a desktop system so having an efficient graphics card is very important to keeping power bills under control. Power is often correlated to heat and so lower power consumption means a graphics card is likely to run slightly cooler and put out less heat into your system meaning your other components will run cooler with improved longevity. AMD and NVIDIA have both made power consumption an integral part of the way graphics cards dynamically overclock so the need for graphics card vendors to use efficient VRM and PCB designs is becoming important to maximise performance. We take power readings after 5 minutes of two different load scenarios: desktop idle and Unigine Heaven load.
Temperatures
The cooling solution which graphics card vendors choose to implement is one of the main differences that consumers have to contend with when choosing a graphics cards. Apart from their acoustic properties, the thermal properties of graphics card coolers are extremely important. Lower temperatures are always better and with AMD and NVIDIA opting to use dynamic overclocking algorithms that take temperature into account it is important that graphics card vendors use high-performance cooling solutions in order to maximise performance. The era of graphics cards reaching dangerous temperatures are now in the past but the importance of lower temperatures still remains. Lower temperatures mean better stability, longer component longevity and lower fan speeds .We take temperature readings after 5 minutes of two different load scenarios: desktop idle and Unigine Heaven load. We always record actual temperatures and make any adjustments for changes in the thermal testing environment.
