Quote:The Taipei Times has reported that the Yuanta Securities Investment Consulting Company has issued an investment note to its clients advising them to expect big things from Nvidia’s next-generation architecture, codenamed Ampere. The note states: ” Nvidia’s next-generation GPU based on the Ampere architecture is to adopt 7-nanometer technology, which would lead to a 50 percent increase in graphics performance while halving power consumption.”
That’s a pretty significant set of improvements, but one of them is a lot more likely than the other. [H]ardOCP has gone offline, but the site previously conducted an extensive investigation of Nvidia scaling over time. While the full articles are no longer archived online, the pages that were available show that the GTX 1080 is often much faster than the GTX 980, particularly when the two were compared in newer titles. Anandtech’s “Bench” results for the GTX 1080 versus the GTX 980 also show strong general uplift.

The idea that Nvidia would cut absolute power consumption by 50 percent, however, seems unlikely and ahistorical. GPUs tend to sell into TDP bands up to ~300-350W (AMD has historically been more willing to push TDP a bit harder than NV). If you compare power consumption figures for modern GPUs, they don’t tend to fluctuate by nearly this much, and there’s been a steady upward trend. Anandtech records full-system loaded power consumption in Shadow of the Tomb Raider as 205W with the GTX 980, 225W with the 1080, 314W with an RTX 2080, and 350W with an RTX 2080 Super. The RTX 2080 Super scores 127.5fps in SotTR according to Anandtech, compared with 52.3fps for the GTX 980, which means it’s definitely a more power-efficient GPU, with a calculated 2.44x increase in frame rate in exchange for a 1.7x increase in power consumption. But it still uses more power in absolute terms.
