Sapphire HD 4870 1GB - Toxic Edition Video Card Review Print E-mail

Sapphire Technology comes back with an upgraded version of their HD4870 Toxic Edition, this time with 1 GB of GDDR5 memory.

When I first saw this card the most obvious eye catcher was the non-reference cooling technique applied. The looks alone are truly both a beauty and a beast. In the center of the glossy black casing you have a quiet 90mm fan and extruding from the inside heatsink we have 3 solid copper heatpipes.

However thats not all keeping this hottie chilled, Sapphire has incorporated its own VCT (Vapour Chamber Technology) for a keeping this pre-overclocked GPU and memory card from overheating. In fact it does such a great job out of the box that you can overclock the Toxic Edition even further!

NOTE: To clarify in the video where it is mentioned about the vapour chamber being in the aluminum heatsink, it is actually all in the copper module in the middle, then the aluminum heatsinks and heatpipes take the heat away from the vapour chamber surface and the memories.

Part 2 below shows how the video card was overclocked and some benchmark results

True PC gamers and enthusiasts will appreciate the Sapphire HD4870 Toxic Edition's outstanding cooling improvements over the regular stock version. The already overclocked graphics card can be pushed to further limits thanks to its innovative "Vapour chamber Technology". Fan noise is low unless you are running it at full load which will increase the RPM and noise levels which is expected. Also the dissapation of heat is exhausted both outside and inside the computer case which is better than just hot air blown into the case only. The bundle in the retail package is complete and a great value added bonus to what you are getting though I would have liked to see a recent game included.
