Sapphire’s Radeon HD 4870 Toxic edition features the Vapor-X heat pipe cooler based on Sapphire’s Vapor Chamber Technology. Vapor-X makes it possible a cool 43°C at idle and a 65°C under load. This Radeon HD 4870 is powered by the RV770 GPU (with 800 shaders processors), has 512Mb of GDDR5 graphics memory with a 256-bit interface and has some overclocked frequencies (memory: 1000MHz, GPU: 780MHz).

In conclusion, my final recommendation on the Sapphire Radeon HD 4870 Toxic graphics card is very good but at the moment it’s nearly impossible to procure. On its own accord the 4870 Toxic would occasionally reach the level of performance seen from the GeForce GTX 260, but never completely dominate over it.

The biggest problem of Radeon HD 4850 is that this card reaches high temperatures (70 degrees celcius) even in idle (i.e. not loaded). So manufacturers decided to discard the stock cooler in favour of a better and more efficient cooler. In these reviews, the Sapphire’s solution, the Radeon HD 4850 Toxic edition, is analyzed. This Radeon features a Zalman heatpipe fan, providing more efficient cooling, quieter operation and more headroom for performance tuning.


Due to the better cooling solution, frequencies have been overclocked:

Toxic Radeon HD 4850 has the following features:
- GPU: RV770
- stream processors: 800
- ROPs: 16
- transistors: 956M
- memory 512Mb / 256-bit
- core clock: 675MHz
- memory clock: 1100Mhz
- DirectX 10 / OpenGL 2.1


However, the Sapphire cooling solution is one of the noisiest cards under idle: around 40db. But this cooler does its job by keeping GPU temperature at least 20 degrees lower than a standard Radeon HD 4850.
