    HIS Radeon 4870 ICEQ4 + TURBO 1024MB

    If there was one graphics card spectacular in 2008, it was the Radeon HD 4870 series. Yet this year a good number of games were released that actually make good use of a frame buffer larger than 512 MB.

    Specifically at higher resolutions with a decent amount of Anti-aliasing and in DX10 games. Suffice to say we'll look at a 1 GB graphics card today. It's based on the Radeon HD 4870 and comes from HIS technology. The all new ICEQ4+ cooling based model.

    Re: HIS Radeon 4870 ICEQ4 + TURBO 1024MB

    HIS submitted their Radeon HD 4870 not only with 1GB of memory, but it also comes with some customizations. And their reflective dual slot IceQ4 cooler is obviously present, and next to that this is the Turbo version, which boils down to the fact that the board is overclocked for you. Normally the Radeon HD 4870 would have a 750MHz core and shader frequency, and this model is clocked at 770MHz as standard for you. Next to that you will also gain some extra memory bandwidth as the memory clock is set at 4000MHz, which is 400MHz higher than the reference clock and these cards really love the faster memory.

    So you always know what to look for in the stores, the packaging. Clean and simple, nothing wrong with that. The components are all well packaged. It's quite a good looking card really. It has a bit of a dark theme going on there, which we prefer a lot. The plastic is made out of UV reflective material, unfortunately most of the sticker is covering that effect up. Now due to the height of the cooler, the graphics card uses up two slots. And all the way to the left are two 6-pin power connectors and you will also find the CrossFire plugs. One molex converter is included should your power supply not have a second 6-pin connector.
