Everywhere I searched for information on this subject, written only about the fact that the GDDR5 memory in some measure compensates for 128 bits.

So, to what extent? Exhausted choice.

Interests in the context of upgrading the video card to connect one monitor 1920x1080 at 60 Hz. Choose from variants with 1024 MB on Board. Thank you.

GDDR3 transfers in one clock cycle (2*bus width) bits. GDDR5 is twice. Because the transfer speed there is no difference. But the influence of different timings, because 128битная GDDR5 will be faster, though not by much.

from the GDDR5 operating frequency is often higher, although in your case you know better where to check.
ie
if (GDDR3Mhz*2 < GDDR5Mhz*4) {
GDDR5=true;
}
else {
GDDR3=true;
}
