Mark Cerny, Chief PlayStation Architect, Explains the PS4 Pro (theverge.com)
Sony's PlayStation 4 Pro, which launches next month on November 10th, is the company's most powerful console that will be capable of outputting 4K and HDR content, including movies, TV shows and games. In an effort to find out how developers will make use of the console and whether or not the PS4 Pro will in any way undermine the audience of the current PS4, The Verge sat down with Mark Cerny, Sony's chief PlayStation architect, and asked him some questions. The Verge reports: The PS4 Pro is 2.28 times more powerful than its predecessor, but not everything will run in native 4K
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.

... does it run Linux?
How bout he explain why there is no Ultra HD blu ray drive in this thing? And how the $300 xbone s has one?
I think they call it N*SYNC.
I'm glad they pay you well, but we can and will hold them accountable for the rest of the company's existence.
So I take it you don't own either console, since Microsoft has done a long list of dick things that make the rootkit scandal appear minor. So uhh...do you own a gaming PC? Do you know how many dick things AMD and Nvidia have done that you should be holding against them for the rest of their lives as companies?
Frankly, I'm surprised you have a computer at all. If you are going to be consistent and boycott every consumer good sold by a company that did an ultra-dick thing at one point in it's history, you should be naked and huddled under some newspapers right now. Oh, wait, I bet the paper company that made them did some bad things.
"Bare-metal" coding / optimization on modern consoles isn't really a thing anymore, according to colleagues working on current gen console games (I worked on consoles two generations ago, but have been mostly on PC since then). Modern console game code, as far as I know, doesn't have access to raw hardware - it's all done through API libraries provided by the OS.
This means that minor changes to hardware specs don't matter as much, since the console OS provides a hardware abstraction layer just like the PC platform does, making backwards compatibility much easier. As a result, I don't foresee either console having many issues with backwards compatibility.
Irony: Agile development has too much intertia to be abandoned now.
They want it to be cheap enough, and are betting on savvy gamers (the target audience here) to be more into streaming services than physical media
