AMD 750K & 760K

[Wingfan]

What are the differences in these? Is the 760K worth extra $10?

[harrynowl]

Maybe if you're overclocking. Otherwise its just clock speed/bin (richland is generally a higher bin trinity)

[AlwaysFSX]

The 760k is a slightly higher clocked 750k. That's it.

[TheGamingBarrel]

The difference is one is clocked/binned higher. (760K)

[flibberdipper]

As said already, the 760K is clocked slightly higher out of the box, but you should be able to push it a little farther than the 750K.

Quoted from Harrware Canucks:

 

So what makes Richland tick? Mostly the same things as its predecessor, but there has been some fine tuning going on behind the scenes which will allow Richland APUs to compete against Intel’s processors on a more level footing. 

While Trinity mated up to four Piledriver cores with a Northern Islands class GPU, and AMD’s next generation Kaveri APUs will use Steamroller CPU architecture paired up with GCN-based graphics, Richland takes a path between these two. It uses the same architectural bones as Trinity, but rolls in several next generation power management optimizations which directly affect clock speeds. As a result, its GPU and CPU cores operate at higher frequencies without negatively impacting TDP.

you can ignore the iGPU parts, but it looks like the cpu side is slightly modified to allow better power management.
