The Radeon 4870 GPU core has been overclocked to 770MHz, at which speed it delivers serious high-definition gaming frame rates. To keep the core busy, there is a new memory sub-system.

Supplied with 1GB of GDDR5 memory running at a peak of 4000MHz, the card has its temperature controlled by the latest version of the legendary HIS cooling technology, the IceQ 4+.

The IceQ 4+ technology draws in cooler air across the GPU and memory, then expels the hot air directly out of the chassis rather than keeping it circulating.

This intelligent expulsion operates in stark contrast to traditional thermal solutions which insist on recirculating the hot air from the GPU inside the chassis.

Peter Yeung, Global Marketing Director for HIS explained the latest advances, "Even though IceQ is the best known GPU cooling solution in the market, we have continued to develop the technology and we're especially proud of the latest version".

"With IceQ 4+, we have redesigned the heat distribution mechanism itself. Utilising a brand new 8mm heatpipe design means we have increased the thermal transfer capacity by 60% over the previous IceQ 4 design", said Yeung. "HIS delivers gamers a triple-advantage of faster, cooler and quieter in-game performance".

Key IceQ 4+ Advantages

1. Faster Dissipation Advantage
   New design offers increased ability to transfer thermal energy - offers rapid cooling
2. Cooler Core Advantage
   Cool air is pulled in from both sides of the fan and heat energy is expelled directly out of the chassis - which ensures great cooling at all times
3. CrossFire Advantage
   The unique airflow system of the IceQ4+ cooler means that even when additional cards are fitted in a CrossFire configuration, each GPU will remain cool
4. Low-Noise Advantage
   Noise levels are reduced and the service life of the graphic card are increased
5. UV Reactive Artwork Advantage
   Perfect for modded chassis - add a UV light and watch your HIS card radiate beautifully

In addition to the HIS 4870 IceQ4+ 1GB graphic card itself, customers will also receive a CrossFire bridge interconnect, DVI to HDMI dongle (capable of carrying 7.1 audio), DVI to VGA dongle, driver disk and manual.

Key Features

HDMI Video and Audio
A system with an ATI Radeon^TM HD 4800 Series graphics card can help enhance the HD entertainment experience by providing a seamless connection to an HDTV or home theater system. With built-in 7.1 surround sound audio (AC3 / DTS ), the new GPUs and graphics cards support single cable connection directly to a compatible HDTV, projector or receiver. This single cable carries both the HD video and 8 channel audio for a clean, high definition connection. Some graphics cards will be equipped with an HDMI connector, while others will output the HDMI signal using a special ATI Radeon DVI-I to HDMI adapter. These options give consumers more options and flexibility when connecting their PCs to monitors or home theaters for maximum enjoyment of HD content. The new GPU also supports xvYCC color which can display a wider range of color when connected to capable HDTVs.
