ATI Radeon HD 5830 - Plugging The Performance Gap, Again

Introducing the Cards

The Gigabyte HD 5830

The Gigabyte HD 5830 might be running on reference clock speeds - 800MHz at the core and 4000MHz DDR at the memory – but it tries to be different by utilizing Gigabyte's specially-designed dual-fan cooler. Coolers with twin fans are not uncommon these days, but what makes Gigabyte's so special is that its fans are inclined at an angle. Gigabyte claims this reduces air turbulence allowing greater airflow and therefore enhanced cooling.

The Gigabyte HD 5830 comes with the dual fan cooler that we've become familiar with, seeing that it has been offered on their high-end cards.

Like most Evergreen cards, the Gigabyte HD 5830 comes with the usual twin DVI ports and single HDMI and DisplayPort.

A closer look at the fan. As you can see it is inclined at an angle towards the heatsink below.


The HIS HD 5830 iCooler V Turbo

As the Turbo suffix suggests, the HIS HD 5830 iCooler V Turbo comes factory overclocked at 840MHz at the core and 4400MHz DDR at the core. The card also features HIS' iCooler custom cooler, which again, as its name suggests, is in its fifth generation. According to HIS, the new iCooler promises not only better cooling efficiency but also lower noise operating levels.

The iCooler cooler is already into its fifth edition and fans of Modern Warfare 2 will definitely appreciate the looks of this card. 

No surprises on the HIS card as it too gets two DVI ports and the a single HDMI and DisplayPort.

Taking a closer peek, we can see the dense cooling fins of the heatsink.

The MSI R5830 Twin Frozr II

MSI's celebrated Twin Frozr II custom cooler makes another appearance, this time on the MSI R5830 Twin Frozr II. We have had great experiences with the Twin Frozr II cooler, so we are expecting this card from MSI to run really cool. That aside, the card also comes with MSI's usual suite of “Military-Class Components”, which includes solid state chokes and Hi-C Caps for better voltage control, overclocking and efficiency. So it's a pity to find that despite all the features the card is packing, MSI has unfortunately decided to go with reference clock speeds for this card.

The MSI card uses the distinctive Twin Frozr II cooler, which comes in its standard silver/chrome finishing.

The oddball of the lot, the MSI R5830 Twin Frozr II sacrifices a DVI port and instead provides a single DVI, HDMI and DisplayPort.

Massive heat pipes are the order of the day, as the MSI card has no less than four heat pipes to quicky draw heat away from the GPU core.
