I am building a new cheap computer and I'm looking at two graphics cards
XFX HD-487A-ZWFC Radeon HD 4870 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP
HIS H487FN1GP Radeon HD 4870 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP
my question is i noticed that the memory clock on the XFX card is 900Mhz, however the HiS has 3600Mhz memory clock. I've been trying to do some research on this but haven't been able to find my answer. I read something about actual clock speed vs ?? (i forgot what it was called) clock speed. and that your actual speed is half of the reported?
If anyone could help clear this up for me I would greatly appreciate it,
also any advice on which one to get would be appreciated too.
