Xbox Project Scorpio's Full Specs Revealed (eurogamer.net)
Microsoft unveiled last year that it will be launching a super-specced Xbox One variant -- codenamed Project Scorpio -- soon. Now the company has shared what those hardware modules look like. According to a report on Eurogamer, which visited Microsoft campus at the company's invitation, the specs of Project Scorpio are:
1. Project Scorpio has 12GB of DDR5 RAM, clocked at 6.8GHz with 326 GB/s bandwidth.
2. Scorpio will be powered by eight CPU cores. It's a custom design sporting 2.3GHz, with a 4MB L2 cache.
3. Project Scorpio will feature an internal PSU (245W) and a compact design, leveraging the advanced cooling techniques pioneered by Microsoft's leading industrial design team.
4. Project Scorpio will achieve six-teraflops of GPU power using a customized design, with 1.172 GHz, 40 compute units, leveraging features from AMD's Polaris architecture.
5. Scorpio will retain the Xbox One S 4K UHD Blu-ray drive.
6. Scorpio will have both HDMI-in and out, 3x USB 3.0, a SPDIF digital audio port, an IR receiver/blaster, and will support Kinect with a USB adapter.
From the report: We saw a Forza Motorsport demo running on the machine at native 4K and Xbox One equivalent settings, and it hit 60 frames per second with a substantial performance overhead -- suggesting Scorpio will hit its native 4K target across a range of content, with power to spare to spend on other visual improvements. And while 4K is the target, Microsoft is paying attention to 1080p users, promising that all modes will be available to them.

That's GDDR5 so it will be counted as quadpumped. In reality it's 1700MHz, slightly slower than a 170€ RX 470 right now. At the stated throughput it's 384bit wide which is fairly obvious with 12GB of RAM.
40CUs with Polaris CUs means 8 more than a RX 470, but it only has "some Polaris features", not all apparently, no real Polaris level GPU then. RX470 has 4960 GFLOPS with 1206MHz clock, so this one will be clocked at ~1150 or less to be able to reach 6000 GFLOPS (they like to add in the few GFLOPS of the CPU cores to inflate the numbers). A RX 480 you can buy off the shelf usually reaches 6000 GFLOPS too.
The CPU seems to be the same higher clocked Jaguar core, same cores just with more L2 cache than before.
So: the original XBox One was a Kabini 8 Core with a DDR3 crippled Radeon 7850, the new one is a tweaked Kabini with a beefier RX 480 videocard and finally decent RAM for its purpose.
