why has the memory bandwidth dropped from 76.8 to 75 ?
Thats about normal. I have my 5770 clocked a little over yours and mine isnt much higher.
it has only dropped with the latest version , when i change the memory to 1250 the bandwidth was 80.0gb/s but @ stock it has always read 76.8
see the changelogs
why the change ? , it has always read gb/s has it not ? . so your readings are differant to ati's , is the change cause of the gtx4** series ?
it has labeled it GB/s but calculated GiB/s .. now it calculates what it claims
before: wrong, now: right .. now: lower ... would you prefer to see the wrong number?
actually .. is the number still too high ?
1200 mhz are 1,200,000 hz * 128 bit = 153,600,00 bits per second * 4 (gddr5) = 614,400,000 bits per second / 8 (bits per byte) = 76,800,000 bytes / 1024 (mbytes) = 75,000 / 1024 (gbytes) = 73.242
anything wrong with that ?
no but why do ati claim 76.8gb/s , it says this amount in the hardware info in ccc
they divide by 1,000,000,000
so it's like harddrives then , ah i see now
if i where you boss i would just say it's more accurate now where people download it from
so you won't have to do all the explaining over and over, just my two cents
Separate names with a comma.
