The NVIDIA GeForce GTX 980 Review: Maxwell Mark 2
See the original posting on Anandtech
At the start of this year we saw the first half of the Maxwell architecture in the form of the GeForce GTX 750 and GTX 750 Ti. Based on the first generation Maxwell based GM107 GPU, NVIDIA did something we still can hardly believe and managed to pull off a trifecta of improvements over Kepler. GTX 750 Ti was significantly faster than its predecessor, it was denser than its predecessor (though larger overall), and perhaps most importantly consumed less power than its predecessor. In GM107 NVIDIA was able to significantly improve their performance and reduce their power consumption at the same time, all on the same 28nm manufacturing node we’ve come to know since 2012. For NVIDIA this was a major accomplishment, and to this day competitor AMD doesn’t have a real answer to GM107’s energy efficiency.
However GM107 was only the start of the story. In deviating from their typical strategy of launching high-end GPU first – either a 100/110 or 104 GPU – NVIDIA told us up front that while they were launching in the low end first because that made the most sense for them, they would be following up on GM107 later this year with what at the time was being called “second generation Maxwell”. Now 7 months later and true to their word, NVIDIA is back in the spotlight with the first of the second generation Maxwell GPUs, GM204.
