Nvidia GeForce GTX 970 And 980 Review: Maximum Maxwell

Test System And Benchmarks

Benchmarking Hardware And Software

The GeForce GTX 980, 9970, and 780 Ti were tested with the 344.07 launch driver, band all of the Radeon cards were outfitted with the Catalyst 14.7 release candidate for testing.

We selected a variety of newer game titles with high detail settings at a resolution of 1920x1080 in order to give the GeForce GTX 970 and its competitors a solid, real-world workload that this class of card should be able to handle. Frankly, it surprised us with its formidable capabilities.

The factory-overclocked EVGA GeForce GTX 970's core clock was dropped to the 1050/1178 MHz nominal/boost reference specification in order to show what a typical specimen should be able to accomplish. Keep in mind that there is no reference cooler for this card, so all GeForce GTX 970s will be unique in this respect.

Two of the games we're testing have an option to use a Mantle code path, so we're running those benchmarks (Thief and Battlefield 4) with Mantle enabled and disabled to measure the API's impact.

High-end graphics cards require a substantial amount of power, so XFX sent us its PRO850W 80 PLUS Bronze-certified power supply. This modular PSU employs a single +12 V rail rated for 70 A. XFX claims continuous (not peak) output of up to 850 W 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 256 GB 840 Pros, so we standardize on these exceptional SSDs.

We'd like to voice our appreciation to Damian and the folks at Memory Express in Canada who helped us with some last-minute equipment requirements in order to perform the benchmarks for this review.  Thanks, gents!
