Vapor X 4890 now available:
SAPPHIRE Adds two new HD 4890 Models with Vapor-X.
I am really curious about the following information, found in the above link:
"The Vapor-X series features high specification solid capacitors and SAPPHIRE ‘Black Diamond’ heatsink chokes for higher efficiency and more reliable operation. The high-polymer aluminium capacitors used have characteristics superior to regular aluminium capacitors for longer product life. The choke is an important component of the power regulation on a graphics card, and the SAPPHIRE Black Diamond (patent pending) choke with integral heatsink runs 10% cooler and with 25% more power efficiency than a normal choke."
Where is states "integral heatsink runs 10% cooler with 25% more power efficiency than a normal choke", does this mean that less heat produced?
I ask because I would really like to have a high-performance video card, but the heat that is output from my case tends to make my small room heat quickly, similar to what member
Denscafon mentions in his post above. If this new choke technology reduces heat output from the card, would it make this better choice than the 4870's and other 4890's in general? Help me to understand the physics please.
