Introduction



AMD's Radeon HD 7970 has been on the market for a while now. The card introduced a new shader architecture and brought numerous improvements in power consumption. It met heavy opposition from NVIDIA's GeForce GTX 680 and 670, which has caused HD 7970's pricing to go down quite a bit.



Sapphire's HD 7950 Vapor-X comes with a large dual-fan cooler that uses the company's famous vapor-chamber technology. On the Vapor-X you will also find a "Lethal Boost" button which switches to a second BIOS with higher clock speeds. With this BIOS, clocks are increased to 950 MHz GPU and 1250 MHz memory.

In our Sapphire's HD 7950 Vapor-X review, we will test both the normal and the boost BIOS (results marked as "Sapphire HD 7950 Vapor-X Boost 3072M").

Pricing of the Sapphire HD 7950 Vapor-X is 330 USD, which is a 10% premium, or $ 30 over the reference design.
