NVIDIA GTX 950 SLI Graphics Card Review

Testing & Methodology

Before we delve into any testing we would like to take this opportunity to overview our test system. All tests will be conducted with the latest stable drivers available, with results will be taken from an average of three tests. All tests will be conducted using the highest factory setting if multiple options are available.

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.

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 inside 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 a note of the ambient; in the case where more than 1 GPU is used an average is created.
