Sapphire has four ranges for most top-end products they offer: standard, Vapor-X, Toxic, and Atomic.

Combining the Vapor-X cooling with overclocks seen on the Atomic, the Toxic brand is the most elite air-cooled video card Sapphire offers. In this article, Benchmark Reviews tests the performance on the Sapphire HD4890 Toxic Vapor-X 11150-01-40R video card against many of the other best graphics accelerator solutions in the price segment.
