I like the review! I tested the 6970 2GB and was pretty nice, but I'll stick to the 460 1GB SLI.
lol... Marco you must have networking on your mind
"memory clock has been increased from the reference design’s 1,250MHz to (5Gbps effective) to 1,300MHz (5.2Gbps effective). "
@acarzt - That's actaully correct.
Umm... hes correct Acarzt.... start googing.
Woah, we posted within seconds.
DANG! 20 degrees cooler??? 20? wow thats a lot!!
I have to say, the Twin Frozr III does not disappoint. A shame that nobody has found a way to overclock the 6950's/6970's even further, we should be able to overclock our cards past 900MHz damnit!
@Taylor - You can OC past 900 if you mod the BIOS.
I get the math.. that wasn't what I was questioning :-P
How do you make the jump from Megahertz to Gigabits per second?
If you're talking about memory bandwidth, that's not even correct as 5.2Gbps does not take into account the bus width.
When talking about clock speeds, it is always referenced in Hertz, not Bits. When talking bandwidth, it would be represented in Bits.
It should read 5.2Ghz Effective.
Ohh, i see what you mean.... Hmm, perhaps the terms interchanged, in the sense that the way its used. I've seen it being used both ways... perhaps the Gbps stuck with me longer than Ghz
In all my years of reading these reviews and working in the IT field, i've never seen(or perhaps noticed) it expressed that way.
I guess if you want to break it down into the math of it all then the terms could be interchangable
1250Mhz * 2read and 2 writes per cycle * 256 bit bus width = 1,280Gbps or 160GB/s
I look at it as there being 5,000,000,000 cycles per second and 256 bits being passed per cycle.
Actually... there is only 1,250,000,000 cycles per second... but there are 4 IOs per cycle... which gives you the "effective" clock
@acartzt - the Gbps rating refers to the acutal data rate of the memory. Even AMD expresses it that way in the specs on AMD.com
If someone watches How I Met Your Mother... then you'll get this one word i'm about to write......
But Acartzt... your right, i've seen Ghz as well... though meh... at the moment, i'm not too concerned about that.... This seems like a great card! uses less power, Is more powerful than stock...... annndn 20 Degrees cooler!! pretty sweet imo.
I see the difference. AMD lists the Memory Data Rate, while everyone else(Nvidia, and System memory Manufacturers) list Effective Clock speed... which is why you get the difference in Gbps, and Ghz.
Also I found some typo's on AMDs website :-)
More reason for me to be an Nvidia fan lol
actually... the more i'm looking around at these specs... it seems like everyone is all over the place and just don't know what to call this...
I think that memory data rate would be most accurate.
The numbers are the same... the names are different.
