AMD ATI Radeon Sapphire Toxic HD 5850 Review – Power Lightning

The AMD ATI Radeon Sapphire Toxic HD 5850 brings a new era for increased level-enthusiasts to ramp up their gaming platforms to Microsoft’s DirectX 11 specification, while maintaining the core platform compatibility to use DVI-D, DVI-I, and finally HDMI for newer LCD monitors. The launch of the Radeon 5000 series has brought with it a change for consumers to meet not only a great price point, but benefit with the core integration of having features such as 1440 stream processors for every GFLOP unit and much more. Incredible design aside of the Toxic HD 5850, the AMD GPU launch of this latest card definitely quenches the thirst for a handful of enthusiasts from overclocking especially to pure stability per MHz increased.

The AMD ATI Radeon Sapphire Toxic HD 5850 looks incredible than the standard reference cards with a Cypress chipcore that is sleek and integrated on the main board. AMD ATI Radeon Sapphire Toxic HD 5850’s comes packed with 1 GB GDDR5 memory, heralded by the 4800 series, and packs 1 gigabyte and over 2 TeraFLOPs of processing power to give an enhanced edge on a 256-bit bus width. The Toxic is naturally overclocked to 765MHz / 1125MHz and Sapphire will be launching the Vapor-X model elsewhere in Europe. One of the best features of design for the ATI Radeon Sapphire Toxic HD 5850 is the cooler, which is a well-done cooler that is quieter than the standard heat pipe arrangement.  Compared to reference coolers, the ATI Radeon Sapphire Toxic HD 5850 cooler has a bimodal air distribution as the air goes through the front and rear of the card and not all out from the back, thereby dissipating the heat much more efficiently. The open-ended design makes cooling more efficient than having a fan behind the card for increased cooling.  The ATI Radeon Sapphire Toxic HD 5850 is definitely a greater card than the AMD reference cards for this line.

ATI Radeon Sapphire Toxic HD 5850 becomes a strong overclocking card with the OC label at the top of the box. With no toolset for overvolting, the volts remained at 1.088v. Using the AMD GPU Clock Toolset, we overclocked this to 145MHz on the core clock frequency and pushed an extra 80MHz on the VRAM frequency to 1195MHz. These overclocks are already in addition to the Toxic card default overclock set, which causes the games to be incredibly fast. The stability and quality of overclocking with the AMD ATI Radeon Sapphire Toxic HD 5850 is simply incredible for the price.

Power consumption efficiency in the Toxic 5530 is also incredibly well done.  The Toxic at 895MHz/1195MHz only adds a mere 25W and is still under the reference specifications released by AMD. In addition to great overclocking, the ATI Radeon Sapphire Toxic HD 5850 has very light decibel load to only 6 dB for sound at full-load while idle and maximum temperatures go from 36 degrees Celsius to 74 degrees.

The ATI Radeon Sapphire Toxic HD 5850 is simply an incredible buy for consumers looking to get the Cypress chip power with DirectX 11 support, Eyefinity power for multi-display processing, incredible overclocking and HDMI onboard output for an incredible power suite on a card that is ingenious as much as it is stable and prurient to enthusiast needs. What sort of release AMD is planning past the AMD ATI Radeon 5970 chipset is still to be seen and remains very promising.
