AMD Unveils its Most Powerful Semi-custom SoC for a Chinese OEM

If anything GDDR is much faster than simple DDR.

Sometimes. If it were that much faster we would all have system ram sticks with GDDR chips on them rather than the standard ones we use today. As I understand it, GDDR is a specialized type of ram that handles graphics information really well, but it wouldn't do so well with the type of data system ram is faced with. It's clocked really high, but also has really high latency.

Programs would have to be written specifically for this platform so as it make each and every memory call a worthwhile memory call.

And the main purpose of this Soc is gaming, so it will be heavily benefited from GDDR RAM.

For it's main purpose which is gaming I agree it will run just as good if not better than XBOX and PS due to it's higher specs but it's the other selling point which is "a little productivity on the side" that got me curious since "It dualboots Windows 10 and a custom Windows 10 IoT 'gaming OS'". I believe many Windows 10 programs are not specifically written with GDDR for it's CPU in mind like let's say Firefox and Excel, can we expect one/both to run like 10% slower or maybe even worse?

I think all apps will be faster or the same fast as with DDR4. GDDR5 is ultra fast in comparison to lose just because of higher latency.

Main reason that DDR is preferred to GDDR is cost and that RAM bandwidth isn't needed to be high to serve the cpu needs, since they usually have 4 up to 64threads to serve (worst scenario) in parallel. GDDR was invented for GPUs since they needed ultra high bandwidth for parallel computing, since they have 1000-5000 shaders to serve and fetch data from and towards them. DDR's only pro is latency but in total it is very slow in comparison. Time will tell though.
