Memory speed of Sapphire x1950xtx?

[The_Iceman]

I've just looked at the Sapphire x1950xtx from scan here http://www.scan.co.uk/Products/Produ...oductID=462632 and I noticed that the memory is shown at 1550MHz (the Sapphire website says this as well) http://www.sapphiretech.com/us/produ...gpid=161&grp=3.

Forgive me if i'm missing something... but I thought the x1950 cards we're supposed to be at 2000MHz for the memory speed? Is this just Sapphire trying to keep it cheap with slower memory?

More confusingly though, on overclockers.co.uk, the same branded card apparently has 2000MHz...

If anyone could clear this up, i'd be very grateful, i'm considering buying one of these, but don't want to get the Sapphire one if it's slower than it should be.

That is the speed of the 1900XTX. Looking at the spec sheet it looks like they've not updated it for the 1950XTX.

X1950XTX should indeed be 2GHz. I assume Sapphire just haven't updated it. All the retailors are showing 2GHz.

Thanks for the re-assurance guys. I ended up ordering it, thinking i'll just send it back if it's not right...

I've just now found a press release from the Sapphire site which does quote the new x1950 as having the correct 650MHz core and 1000MHz memory, so looks all good

Dude the new ATI card is 650MHz core clock & 2000MHz GDDR4 memory, you typed 1000MHz.

650/2GHz ...nice bandwidth.

1Ghz= 2GHZ

DDR means double data rate so data is transmitted on both the rise and fall of the clock signal, meaning that the effective data rate is twice the clock speed. Thus a 1 GHz clock on the memory results in 2 billion transmits a second (2 GHz for all practical pourpases).

1Ghz= 2GHZ

I allways thought 1GHZ = 1000MHz, 2GHz = 2000MHz. I also noticed the ATI X1950 series @ 650/1000 & 650/1550 650/2000/2GHz. Maybe it's just a selling tactic?.

A new design from ATI then?, i havn't read any reviews yet about this.

So your saying 1000MHz=1GHz is really 2000MHz=2GHz, DDR4 double pumped or something through ATI's ring- bus, lol.

Goss... its double for RAM... it always has been (1000Mhzx2=2000Mhz) hence the DDR notation... http://en.wikipedia.org/wiki/Double_data_rate

Yeah i understand the DDR double ram, just a missunderstanding, 500x2=1000, lol my bad, my brain is in the drain.
