RX 5700XT memory overclocking?

Is it me or are the Navi 10 cards bandwidth restricted? Between stock 875, and up to my 925mhz memory clock, there is no discernible difference in synthetic or real world use. Performance and numbers are all the same.

You should see an increase in synthetics with memory overclocking.

It's not bandwidth starved though.

the 5700 XT has (almost) identical memory bandwidth to a 1080 Ti and the 1080 Ti is quite a bit faster.

If a card isn't memory bandwidth starved then increasing the memory speed isn't going to do much, just like OCing your CPU when you're GPU bound isn't going to help performance much.

Intel i9 9900K Coffee Lake @ X8 5309mhz (+47.5%)
AMD FX-8320 Vishera @ X4 5022mhz (+43.5%)
Intel i5 4690K Haswell @ X4 5013mhz (+43.2%)
AMD X4 960T Zosma @ X6 4870mhz (+62.3%)
Intel i7 6700 Skylake @ X4 4709mhz (+38.5%)
Intel i5 6400 Skylake @ X4 4588mhz (+69.9%)

...
Not disagreeing with your conclusion, but might the 1080ti's 384 bit memory bus (vs. 256 bit for 5700XT) have something to do with it too?
