Frame latency spikes plague Radeon graphics cards

crookedvulture writes "AMD is bundling a stack of the latest games with graphics cards like its Radeon HD 7950. One might expect the Radeon to perform well in those games, and it does. Sort of. The Radeon posts high FPS numbers, the metric commonly used to measure graphics performance. However, it doesn't feel quite as smooth as the competing Nvidia solution, which actually scores lower on the FPS scale. This comparison of the Radeon HD 7950 and GeForce 660 Ti takes a closer look at individual frame latencies to explain why. Turns out the Radeon suffers from frequent, measurable latency spikes that noticeably disrupt the smoothness of animation without lowering the FPS average substantially. This trait spans multiple games, cards, and operating systems, and it's "raised some alarms" internally at AMD. Looks like Radeons may have problems with smooth frame delivery in new games despite boasting competitive FPS averages."
