The Exigent Duality

Dating back to the earliest days of laptops with 3d accelerators, there has always been a significant performance gap between desktop graphics chips and their laptop-oriented counterparts. Graphics card hierarchy tables always appropriately had them placed multiple tiers apart in terms of capability.

One thing that I didn't see coming-- but could have, had I given it some thought-- was that the decreasing power consumption of today's GPUs means that laptops no longer need to play second fiddle: astoundingly, the mobile GTX 1070 is not only equivalent to in all cases, but is actually faster than in some instances, the desktop variant of the chip!

I still have a difficult time recommending gaming laptops to people, because they tend to die young deaths due to the inability to dissipate heat properly from their tiny-and-cramped toteable casings. But even that worry might be diminished with this new, cooler-running generation of GPU!
