Instead of using an entirely new GPU, Cerny said the PS4 Pro is using a "double-sauced one." In effect, the new console has a second, identical GPU configured next to the original, more than doubling the processing power of the Pro. While the standard PS4 produces 1.8 teraflops, the PS4 Pro achieves 4.2 teraflops. This is how the device can achieve native 4K and, in some cases, what Cerny said are results "extremely close to 4K." For select software, including games like adventure title Horizon Zero Dawn and Call of Duty: Infinite Warfare, the PS4 Pro will use a crafty technique called checkerboard rendering to achieve 2160p resolution. Checkboard rendering changes the formation of pixels to achieve higher-fidelity graphics.
Standard PS4 games will play just the same unless devs patch them
For the more than 700 or so existing PS4 games, Cerny said the goal was to ensure those titles played smoothly no matter what. That's why the Pro incorporates an identical GPU. Because the new console has "the old GPU next to a mirror version of itself," Sony can support existing games with a simple trick: "We just turn off the second GPU," he said. Developers can patch these titles to boost graphics and performance in very subtle ways. But unless you have a 4K television, the difference will not be substantial.
Sony says it doesn't want games released solely for the PS4 Pro
When asked whether Sony would ever let a game run exclusively on the PS4 Pro, Cerny was blunt. "We're putting a very high premium on not splitting the user base in that fashion," he said. That doesn't rule out the possibility that, two or even three years down the line, a game comes out that relies so heavily on the hardware improvements of the Pro that it becomes unplayable on the standard PS4. Cerny wouldn't really speak much to that scenario, saying that Sony is asking developers to take advantage of the new console without leaving older hardware behind.

Since June of this year, educational toy company Roylco recalled 1,400 light tables designed for kids... Razor, Swagway and some eight other manufacturers recalled a total of 500,000 hoverboards. And HP and Sony between them recalled more than 42,000 notebook computers. All for similar reasons -- lithium-ion batteries that either had caught fire or which have posed a fire hazard... Other notorious examples include the several different Tesla Model S's that have caught fire, typically after crashes compromised their battery packs, and Sony's wide-scale recall a decade ago of the batteries that powered its Vaio and other laptop computers.

The company also launched a more powerful version of the PlayStation 4: the PS4 Pro, which offers support for 4K. It is priced at $399, and goes on sale November 10. The Verge reports: The PS4 Pro can output 4K and HDR video, which is powered by an upgraded GPU. Sony also boosted the clock rate for the new PS4 Pro. It will also come with a 1TB hard drive. "PS4 Pro is not intended to blur the line between console generations," Mark Cerny, the chief architect for the PS4, said on stage. "Instead, the vision is to take the PS4 experience to extraordinary new levels."
