88% increase over the design value? How in hell could that happen? Normally it goes in the other direction.
My imagination failing me.
"oh, we have actually builit in a wider bus in there? niiiiiiice."
"look, I've tried higher clocks today and it worked!"
Not possible. Because that means the GPU clock rate is doubled (Calm your shit Kotaku, I'm using this as an example). They are saying they are doing a read AND write at the same time. So it "doubles" the bandwidth... (102x2 = 204GB/s)
Except they said 88% increase... = 192GB/s... but... where the fuck did that number come from? Why wouldn't it be able to be a 100% increase? Well... because you'd have things trying to right and read to conflicting spots at the same time.
So that's why they say "realistically" it's 133GB/s....
But wait... if the 88% increase isn't account for those conflicts and data misses... then how did they make up that number?
So...currently.. they say:
128 (bit) x 800 (clock rate) = 102.4GB/s
Well.. downclocking the GPU from 800 to 750 (going down 50) will get you...
128 (bit) x 750 (clock rate) = 96GB/s
Double that since they are saying you can read/write at the same time...
96 x 2 = 192GB/s
So... several of us are thinking this 88% thing is just a bullshit number they came up with after changing around their GPU clock and "double accessing" the RAM.
