How We Tested
Nvidia's GeForce GTX 980 is one of the most powerful and energy-efficient graphics cards we've ever tested. It's a product we tested in depth in "Nvidia GeForce GTX 970 And 980 Review: Maximum Maxwell". Those of you unfamiliar with the GeForce GTX 980 are encouraged to read that piece for detailed GPU info and game benchmarks. In a nutshell, the GTX 980 is about as fast as the GeForce GTX 780 Ti, with a much lower 165 TDP and a $550 MSRP.
Today, we're focusing on Zotac's GeForce GTX 980 AMP! Omega Edition and what differentiates it from other models on the market. To that end, the emphasis is on the cooler's thermal and acoustic performance. Then, we'll examine power usage and test overclockability. All of this data will be compared to the reference GeForce GTX 980 design.
Graphics cards like the GeForce GTX 980 require a substantial amount of stable power, so XFX sent us its PRO850W 80 PLUS Bronze-certified supply. This modular PSU employs a single +12V rail rated for 70A. XFX claims continuous (not peak) output of up to 850W at 50 degrees Celsius.
We've almost exclusively eliminated mechanical disks in the lab, preferring solid-state storage for alleviating I/O-related bottlenecks. Samsung sent all of our labs 256GB 840 Pros, so we standardize on these exceptional SSDs.
