14 DAY TRIAL // Hong Kong-based Hightech Information System Limited is reportedly preparing the custom-designed, perfectly silent and fanless HiS AMD Radeon HD 7750 iSilence 5 video card.
The card is built on AMD’s “Cape Verde XT” graphics processing unit that comes with a very small 123 square millimeters die size, containing 1.5 billion transistors. The default GPU speed is 800 MHz when working in full load 3D mode.
In 2D mode, the frequency of the GPU will drop to a low 300 MHz.
The 1024 MB of GDDR5 memory is clocked at 4500 MHz when in 3D mode, but drops to 600 MHz when working in 2D.
The memory and the GPU work on a tight 128 bit BUS, so playing games with very high resolutions will be a little tricky.
The “Cape Verde XT” GPU is part of AMD’s GCN architecture and comes with much improved GPU compute performance.
The GPU has 512 unified shader processors, 32 texturing units and 16 ROPs.
Compared with the AMD Radeon HD 7770 GHz edition, this is a cut down “Cape Verde” GPU with two of its 10 CUs (compute units) disabled and a 20% lower clock speed.
On the connectivity side, the HiS AMD Radeon HD 7750 iSilence 5 video card comes with one DisplayPort connectors, a HDMI interface along with a dual-link DVI.
The custom-designed HIS iSilence 5 cooling system has four copper heatpipes that are cooled by a blue set of cool-looking aluminum fins.
The four heatpipes come in direct contact with the GPU die and have a large 8 millimeter diameter.
This is more than enough to satisfy the cooling requirements of the “Cape Verde” GPU, as it will draw a maximum of around 75 watts when in full 3D mode. When idling, the “Cape Verde XT” will consume a minuscule 3 watts.
HiS’s new AMD Radeon HD 7750 iSilence 5 will be a perfect fit for NoFAN’s CS-70 and CS-80 computer cases and a great companion for the NOFAN CR-95C Copper Cooler.
