The Rampage 700 is surely Gainward's rather unorthodox version of the Radeon HD 4870 X2 graphics card. The main thing that sets it apart from the reference card is its cooler. The reference design relies on a large dual slot cooler which covers the entire length of the card. It manages to keep GPU temperatures under 90°C, and although it's not too loud, it's not something we'd characterize as quiet either. Its biggest drawback is relatively low overclocking potential which results from the rather high core temperatures. Gainward's Rampage 700 on the other hand, manages to stay cooler although it's overclocked. There's a price to pay for better cooling performance and it's obvious at first glance, it's an immense card which takes up three slots on your motherboard. - FudZilla

Gainward Rampage 700 Goes Like Hell Style Preview

You can't see its bulk from this angle, although you can see two large fans. The heatsink features four copper heatpipes and a multitude of aluminium fins for efficient heat dissipation. Although it's much bigger than the reference card, the Rampage 700 is not much heavier. The reference cooling has two heavy copper blocks on its GPU's, along with a smaller, aluminium heatsink. Gainward's cooler has a huge aluminium heatsink, and a slightly smaller copper base, thanks to the heatpipe technology. The PCB wasn't changed. It is the same length and still relies on 6-pin and 8-pin PCI Express power connectors for external power.

Gainward has two flavors of the Rampage 700 and they both feature the same heatsink. The first one is the slightly slower Rampage 700 Golden Sample, but today we're testing the faster version, dubbed Goes Like Hell. It is overclocked to 790MHz for the GPU, just 40MHz over the reference 750MHz. The memory was bumped up from 1800MHz to 1900MHz. Like all Radeon HD 4800 series cards, the double headed 4870 X2 is based on the RV770 core, having 800 shaders with full DirectX 10.1 support. As for the memory, the Radeon HD 4870 packs 2GB of GDDR5 memory and remember these cores don't have a shared frame buffer.

The huge cooling solution performs flawlessly and we measured some rather low temperatures. And more importantly, it's quiet. It's rather huge backplate has four connectors, including DisplayPort and HDMI. There's plenty of spare room for ventilation or other connectors. The Rampage 700 2GB version also got a new mean looking box, which ended up slightly larger than your average box, thanks to the huge heatsink. Our first results don't reveal much of a performance lead compared to the reference card. However, 3DMark Vantage isn't a game, and we'll make our verdict once we complete our gaming tests.

In any case we compliment Gainward for the mere fact that it offered a triple slot card. We like a challenge and we like unusual things, and we especially like the fact that this is probably one of the fastest graphics cards on the market. But time will tell in the future what this Rampage 700 is really capable of in some real gaming environment.
