What is 5ghz memory in terms of clock speeds?

post #1 of 6
Thread Starter 
Everytime i try to look up the reference 290 memory clock speeds, i always get 5Ghz or 5.6GHz

what the hell does that mean? i just want the actual numbers, like my gpu has 1040 core clock and 1350 memory clock

Quad data rate, so you divide those giant numbers by 4, i.e 5Ghz memory is 1250mhz

Thats the memory speed. GDDR5 is quad data rate. So the memory speed is 1500mhz. 15x4 is 60, add the 2 extra zero's and you have 6000mhz or 6ghz.

Just an example.
