In keeping with the rest of their TOXIC range, this offering features increases to both core and memory clock speeds over a reference boards - While the card's RV770 core gets a modest 30MHz boost for a final clock speed of 780MHz, the GDDR5 memory on board gets a more substantial 100MHz increase, with the 1000MHz memory clock offering up some impressive memory bandwidth improvements.

The Radeon HD 4870 TOXIC's cooler also gets a complete overhaul from AMD's reference solution - While it remains a dual-slot affair, the cooler itself is a copper block sporting three heatpipes coupled with numerous aluminium fins, and an 80mm fan on top of it all to provide airflow to the cooler. The Radeon HD 4870 TOXIC also makes use of Vapor-X vapour chamber cooling technology - Its interesting stuff and effective to boot.
