Sapphire Radeon HD 4870 Toxic Review

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.

Sapphire Toxic Radeon HD 4850 Review

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.

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

3D LCD Monitor

Sapphire Technologies unveils a new LCD monitor that uses “a new stereoscopic graphics driver” to create 3D images — glasses required. The driver works with ATI graphics cards to send a polarized image to the dual-layer monitors, which displays a 3D image to viewers with special glasses.

Sapphire’s Super-High-Resolution Monitor: 56 Inches of Fun

Sapphire will be launching the 56-inches monitor in Q3, and the display’s standout feature was the resolution: a pixel-tingling 3840×2160 which is over twice as high as Dell’s 3008WFP.
As such, the $59,000 (US) panel will ship with a Sapphire FireGL workstation card, equipped with the necessary twin dual-link DVI output needed to run the esoteric resolution.
