Your the one making redundant sh** out of damage control. Your mind can't get away from simple marketing model numbers and code names.
As MS also mentioned, 10 precent reservation is only temporary LOL.

How much more powerful?
AY: It depends what youre doing. GPU, like 40 per cent more powerful. DDR5 is basically 50 per cent more powerful than DDR3, but the memory write [performance] is bigger on Xbox One so it depends on what youre doing.
http://gamingbolt.com/oddworld-inhabitants-dev-on-ps4s-8gb-gddr5-ram-fact-that-memory-operates-at-172gbs-is-amazing
Gilray stated that, It means we dont have to worry so much about stuff, the fact that the memory operates at around 172GB/s is amazing, so we can swap stuff in and our as fast as we can without it really causing us much grief.
7870 XT's memory operates around 192 GB/s LOL. So what...
---
X1 has 12 CUs at 853Mhz with real 55 GB/s DDR3 + 150 GB/s ESRAM memory bandwidth.
Prototype 7850 has 12 CUs at 860Mhz with theoretical 153.6 GB/s memory bandwidth.
---
7790 (96 GB/s theoretical) has less memory bandwidth than 7850 (153.6 GB/s theoretical) LOL. Only a fool can't see that.
lol
From what i can see you can't many anything for your self,even my reply you copy and pasted them...hahaha
No MS say that latter they could free something,how much who knows fact is they could be bluffing for all we know,those reservations were done so that the system did not suffer while multitasking running snap of Kinect.
As of now is 10% period.
The xbox one doesn't have a 7870XT so is totally irrelevant to the topic at hand,but this is not new when you see your self pin in an argument without anything to reply you run and hide on PC,like if that changed anything the xbox one doesn't have a 7870 XT..haha
The xbox one has 14 CU from those 2 are disable because MS disable them to get better redundancy,they even think about using them,so yeah it is a 7790,with 2 CU off and lower clock speed.
Yeah that number is also cut back to 140Gb/s and i am sure those are the very best case scenarios,i know it could be lower.
The xbox one 1.18Tf is 600Gflops less than a 7790 only a trueeeeeeeeee fooooollll can't see that..hahahah
1. "Copying and pasting" from SDK examples or source documentation or other materials are part the job LOL. It would be waste of time to hack a GPU driver without documentation.
2. No, MS haven't implemented the two concurrent render pipes for game and system services, hence relying on 10 precent time slicing reservation method.
http://www.eurogamer.net/articles/digitalfoundry-microsoft-to-unlock-more-gpu-power-for-xbox-one-developers
"Xbox One has a conservative 10 per cent time-sliced reservation on the GPU for system processing. This is used both for the GPGPU processing for Kinect and for the rendering of concurrent system content such as snap mode," Microsoft technical fellow Andrew Goossen told us.
"The current reservation provides strong isolation between the title and the system and simplifies game development - strong isolation means that the system workloads, which are variable, won't perturb the performance of the game rendering. In the future, we plan to open up more options to developers to access this GPU reservation time while maintaining full system functionality."
Once you get over the initial surprise that the background system takes up quite so much GPU time in the first place, the notion of being able to give developers access to this resource while not compromising functionality may sound rather like having your cake and eating it, but Microsoft points to particular aspects of the GPU hardware that make this scenario possible.
"In addition to asynchronous compute queues, the Xbox One hardware supports two concurrent render pipes," Goossen pointed out. "The two render pipes can allow the hardware to render title content at high priority while concurrently rendering system content at low priority. The GPU hardware scheduler is designed to maximise throughput and automatically fills 'holes' in the high-priority processing. This can allow the system rendering to make use of the ROPs for fill, for example, while the title is simultaneously doing synchronous compute operations on the compute units."
With dual rendering command pipes, X1's GPU should be able to give back the unused GPU power to devs when system is not using Kinect and GUI snap features.

3. The context for 7870 XT's 192 GB/s memory bandwidth has nothing to do with X1 and only deals with your "memory operates at X" interpretation.
4. http://semiaccurate.com/2013/08/30/a-deep-dive-in-to-microsofts-xbox-one-gpu-and-on-die-memory/
Microsoft sources SemiAccurate talked to say real world code, the early stuff that is out there anyway, is in the 140-150GBps range, about what you would expec.
204 GB/s is for ESRAM's theoretical bandwidth.
5. 7790's PC benchmarks would NOT reflect X1's results since there are big differences with memory bandwidth period.
Your 7790 selection doesn't come close to replicate 12 WORKING CUs at 853Mhz with real 55GB/s DDR3 + 150 GB/s ESRAM bandwidth.
My view on the closeness between the two boxes are well supported by multiple statements from devs (with their name).
