In an old aviation magazine I've read that russians are trying to apply a new type of stealth material for their engine blades. So, maybe it's that.
T50's conventional cone shaped exhaust is not stealthy, hope china doesn't follow

My understanding of the T50 is that it is just a prototype. Could the reason behind the large intake due to it (the T50) using an older type of engine at this point?
We haven't seen the JXX yet, but if it is also using older engine for the prototype test phase, wouldn't we also expect it to have large intake also?
Sorry, I have very limited knowledge of engine and intake design. Just putting the above forward for input from someone who have better understanding in this field.

That doesn't make sense. You mean different form factors for prototype and production model. That would require re-design.
the blades likely a radar blocker. if you look boeing F-36 ,you also notice the radar blocker.the radar blocker and her inlet was coated with RAM,it disperses the incoming RF..
other aircraft such as EF-2000,F-15SE.J-11B and F-18C also fitted with radar blocker.

I think you mean X-32?
There is this big S-Duct debate at AFM.
F-22, F-35 won their respective competitions and had large serpentine (S) ducts. YF-23, X-32 Did not have that. They ended up losing their respective competitions but they did not lose because they were inferior in RCS reduction. In fact the YF-23 and even the X-32 was said to have a lower RCS that their competition. They lost due other reasons. X-32 was gaining allot of weight and YF-23 was much more complex design than the YF-22.
F/A-18E/F, EF-Typhoon have simple radar-blockers installed.
An S-duct is not a must when it comes the shielding the compressor face. It is one way of doing it.....

I can imagine having the radar-blockers would affect the engine's overall performance. Maybe that could be part of the reason the YF-23 and X-32 lost out. If radar blockers are that effective, why are they still complaining of the flankers having big RCS and not go ahead installing the blockers instead.
Radar blocks are only part of the problem. The flanker is a massive and unstealthy airframe that has protrusions everywhere.
The reports stated that the YF-23 was actually stealthier than the YF-22.
