In terms of market coverage, Sapphire
has the ATI Radeon line covered. From mild to wild, they have a video card for just about any application and budget. While the low end and mainstream cards are nice, it is the extreme, high performance cards that really grab your attention. The card provided for this review is definitely one of the latter!
The Sapphire Toxic Radeon HD4870 512MB graphics card takes the already solid performance of ATI's top of the line single GPU solution and rachets things up a little higher with a factory overclock and a unique cooler. The promotional image below provides a quick look at the card in question, while the rest of the review will take a closer look at the aggressive styling and performance features it has to offer.
Before taking a closer look at the unit provided for review, let's take a look at some published data on the Sapphire Toxic Radeon HD4870 512MB graphics card. The key things that the information below tells us is that the Toxic version of the Radeon HD4870 has been overclocked by 30MHz (4.0%) on the GPU and by 100MHz (11.1%) on the memory. While neither increase is extreme, it should be interesting to see how a top of the line card such as an HD4870 performs with an extra boost right out of the box.
