Asus is redesigning its Radeon HD 7950 DirectCU II graphics card lineup, making it a little bit smaller and compact. The new revision/design of the Asus Radeon HD 7950 DirectCU II is said to be implemented to both the DirectCU II Standard and TOP variants.
The new design of the Asus Radeon HD 7950 DirectCU II will feature a more compact cooler and a denser aluminum fin stacks. It will have 6 heat pipes, instead of 5, to draw the heat from the the GPU, memory and MOSFETs. It will also have a secondary heatsink that covers the entire length of the PCB. The PCB of the new revised Radeon HD 7950 DirectCU II will also be smaller.
The display output of the revised Asus Radeon HD 7950 DirectCU II is also changed. It will have one HDMI output, one DisplayPort and two DVI DL outputs, compared to the original that has one HDMI, two mini-DisplayPort and one DVI.
Aside from the design of the graphics card, the Radeon HD 7950 DirectCU II (base model) will have 800MHz of core clock speed, 5GHz of effective memory. While the Radeon HD 7950 DirectCU II TOP will have 900MHz of core clock speed.
With regards to the prices, the revised Radeon HD 7950 DirectCU II might be sold at a similar price to the original models, or it might be sold slightly cheaper.
I check the prices of the current HD 7950 DirectCU II on the market, and indeed the prices are starting to fall. You can check the updated (discounted) price of the Asus Radeon HD 7950 DirectCU II here, while for the HD 7950 DirectCU II TOP version you can see it here.
