Sony's PlayStation 4, which will go on sales in two months, comes loaded with rendering pipeline and some proprietary upscaling techniques that can improve lower resolution base signals to take fuller advantage of a 4K display. Microsoft is seemingly upset with how Sony is marketing this, and it is not shying from telling people that no amount of upscaling can fill in those missing 4K pixels and the hardware inefficiency to produce native and "true 4K" images that the Project Scorpio, its gaming console that is coming next year can. Microsoft has also said that any game that it will launch during the Scorpio timeframe will "natively render at 4K." But the debate is anything from over because Microsoft keeps reminding everyone that the processor and GPU in its upcoming console is more powerful. As ArsTechnica explains: With Scorpio, Microsoft seems to be arguing that every first-party game at launch will be able to generate and render nearly 8.3 million pixels (four times as many as a 1080p game) at an acceptable frame rate (i.e., at least 30 times a second). That would be quite an achievement. As we noted back at E3, it currently takes pricey, high-end PC graphics cards like the Nvidia GTX 1080 or the AMD R9 Fury X -- cards that run $300 or much higher -- to "barely scrape by" with a native 4K, 30fps game. And those PC cards seem to have significantly more raw power than what is being claimed by Microsoft -- 9 and 8.4 teraflops, respectively, vs. a claimed 6 teraflops for Scorpio (and 4.2 teraflops for the PS4 Pro).Microsoft's head of Xbox planning, Albert Penello said, "I know that 4.2 teraflops is not enough to do true 4K." In an interview with Eurogamer, Penello adds:I think there are a lot of caveats they're giving customers right now around 4K. They're talking about checkerboard rendering and up-scaling and things like that. There are just a lot of asterisks in their marketing around 4K, which is interesting because when we thought about what spec we wanted for Scorpio, we were very clear we wanted developers to take their Xbox One engines and render them in native, true 4K. That was why we picked the number, that's why we have the memory bandwidth we have, that's why we have the teraflops we have, because it's what we heard from game developers was required to achieve native 4K.
