new 4850 heatsinks ?

[Dicehunter]

Ok so when i ordered my 4850 1GB i expected it to look like this, -( http://www.overclockers.co.uk/showp...HDMI (PCI-Express) - Retail (188-01E81-00ASA) )- but it looks like this
-( http://www.overclockers.co.uk/showp...DVI/HDMI (PCI-Express) - Retail (11147-00-20) )- .
Now it says on the box 4850 1GB and in gpu-z aswell but why is the cooler different, Are the big round coolers better than the slim versions ?

I bought the EAH 4870 and in the picture on OCUK it shown a full fascia cooler but when arrived it had a pretty big golden heat-sink. Not a problem though the temps are well below 50 idling with 20% fan speed.
