Xani :
Not really, in modern times, it is very very useful to know what type of DDR5(the company) had produced that DDR cause not every company has the same quality and little things... similar to why you always check the Company making the DDR on your PC .. -_-
I call BS. The author only wanted to find out which type of DDR was his GPU, whether it is DDR3 or GDDR5. Actually, according to what you said, this is the same story: it's like buying a car and wanting to find out who made the leather that your seats are made of - yes, nobody cares since it is a minor part of the "thing" and only the producing company takes care of it, including warranty.
Also, i would like to know why it is "very useful" to know who produced my GDDR5 VRAM memory chip on my GPU? Are there any statistics claiming that for example MSI's GDDR5 is better than ASUS's?
