is there any other difference between 390 to 390x?

[Mr Fister]

i know the core speed is 50 in difference between the two, also the tdp is significantly different (about 100 TDP in range)  but what else?

There is an x in the name

I do not know

The 390 has 2560 cores, the 390X has 2816 cores (10% more). They also both have a TDP of 275W, not sure where you saw they were different.

[Naijin]

390x is slightly faster, as it has a higher core count and higher floating point performance. It's a small difference, but it's yours to determine if it's worth the price difference.

The " X " means it's overclocked.

Again! NO! That's only the case for R9 270 series!

specs shows the 390 with 275TDP and 390x with 375TDP

Must be a typo. Everywhere I look says 275W TDP for both.

I really wish they produced that reference cooler. I want it even if it would kill my ears its just so sexy

Yes you are right. The nitro version is 375TDP. the MSI isnt

Mostly all the same thing, Compute Units is another way of saying how many cores it has (1 CU = 64 cores), texture units are also paired with groups of cores. Core clock is just the core frequency (1000MHz, etc.)

so do i really need them for a 100$ more?

[Mahigan]

CU or compute units are arithmetic logic units. They perform/solve complex mathematical equations. They're used, predominantly, for shaders as well as post processing effects such as motion blur, depth of field, lighting etc.

TMU or texture mappings units are responsible for attaching details to polygons. The rasterizer and hierarchical Z units draw a wireframe of an image. The TMUs attach akin, hair, clothing, and any sort of texture in a scene, to the wireframe.

Core clock is the speed at which every unit, in a GPU, operates. The higher the core clock the quicker the units can do their work per second/and/or cycle.

You don't"need" to buy an R9 390x over an R9 390. In fact id say the R9 390 is the better buy in terms of price/performance.

Am I the only one that likes the look of the reference cooler?

This..

Plus if your aiming for about the 390x level of performance,the 390 + an Manual OC could do the same performance levels just as easily...

 

Note.... that the 390x can be pushed too....

 

Figure out how much GPU power you require by looking up 390/390x reviews, find your prices for each... is the higher cost worth that extra performance (in your opinion)?

do you think its worth it? im not a guy who upgrades every 2 years... my gaming pc never got upgraded for 5 years!

[lxyfutures]

In my experience, if you want to know their performance difference, in 1080P the difference is not obvious. Like in GTA5 ,veryhigh setting and msaaX2, 390 can go like 55 fps when driving(without too much grass or trees),and 390X is like 60fps.
