HIS 7730 iCooler 1GB GDDR5 PCI-E DVI/HDMI/VGA graphics card review and testing

Company Hightech Information System Limited specializes in the production of graphics accelerators based solely on the company AMD chips. At the same time its devices always stand out by unique features and additional capabilities.

This material will be devoted to graphics card HIS 7730 iCooler 1GB GDDR5 PCI-E DVI/HDMI/VGA which can complement inexpensive processor without integrated graphics core, allowing to create a low cost and reliable computer for home or office.

Also note that for convenience we will use the shorter its name: HIS 7730 iCooler 1GB GDDR5 or HIS H773F1G.

Package and content

HIS 7730 iCooler 1GB GDDR5 (H773F1G)

Box HIS 7730 iCooler 1GB GDDR5 is made of cardboard and colorfully decorated. On the front side some of the features are listed:  

  • microarchitecture AMD GCN;
  • 1 GB of fast memory GDDR5;
  • HDMI port with support to display image in the resolution 4K Ultra HD;
  • proprietary software for overclocking and monitoring (HIS iTurbo).

On the reverse side of the package in the form of visual icons, are listed all technologies that supports graphics accelerator, as well as connectors.

Also here is a description of the minimum system requirements for the computer. In particular, it must be equipped with 4 GB of RAM and a power supply unit of 400 W. If you plan to install two similar graphics cards in mode AMD CrossFireX, you need a power supply unit with capacity at least 500 W.

The side face has two stickers with the serial number and name of the graphics accelerator.

Inside the top decorative packaging there is another box made of black cardboard. Graphics card HIS H773F1G is securely packaged using a special foam form and anti-static bag.

HIS 7730 iCooler 1GB GDDR5 (H773F1G)

Supplied set of HIS 7730 iCooler 1GB GDDR5 is quite standard and contains:

  • instructions of accurate installation of a graphics accelerator in the slot PCI Express 3.0 x16;
  • quick reference guide;
  • CD with software and drivers;
  • sticker on the computer case.

This small set includes everything you need for connection as this card does not require any additional power supply or adapter for interface panel connectors.

The hero of this review is equipped with the following set of interfaces for image output:

  • 1 x Dual-Link DVI-D;
  • 1 x HDMI;
  • 1 x D-Sub.

This video output configuration is designed primarily for entry-level systems, because it allows you to connect digital (DVI-D, HDMI) and analog (D-Sub) monitors without using additional adapters. However, in multi-channel mode only digital displays can operate.

If we talk about support of resolution, it depends on connector of the computer:

  • HDMI - up to 4096 x 2160;
  • Dual-Link DVI-D - up to 2560 x 1600;
  • D-Sub - up to 2048 x 1536.

Design and circuitry

HIS 7730 iCooler 1GB GDDR5 (H773F1G)

Model HIS H773F1G is made on a blue PCB and has very compact dimensions: total length does not exceed 160 mm, and height - 112 mm. This greatly expands the number of compatible cases, which is especially important in entry-level systems.

As we can see the graphic chip has a protective frame which improves the security of installation and removal of the cooling system.

The power subsystem is based on the graphics accelerator according simple scheme: two phases for the GPU and one for the memory chips. Chip Richtek RT8841 is used as the controller. It can control four power supply phases. At the same time it is installed on the back side of the PCB.

In addition to the above-mentioned controller the reverse side of the PCB has few elements of the power subsystem and three stickers with technical information.

The graphics card is based on the graphic chip AMD Cape Verde LE which is made according to 28-nm technology process based on microarchitecture AMD GCN. It consists of 384's unified shader pipelines, 24 texture units and 8 rasterization units. Graphics processor operates with frequency 800 MHz in the nominal mode and can be slowed down to 300 MHz in idle mode.

Memory capacity 1 GB is collected through 4 chips SK Hyunix H5GQ2H24AFR-T2C, each of which has a capacity of 256 MB. According to the documentation their nominal frequency is 5000 MHz, but in our case it was lowered to the recommended by AMD 4500 MHz. Data exchange between the graphics processor and memory is performed via 128-bit bus with bandwidth of 72 GB/s.

Cooling system

HIS 7730 iCooler 1GB GDDR5 (H773F1G)

HIS H773F1G accelerator is equipped with a proprietary cooling system iCooler which occupies two slots for expansion cards. It almost does not exceed the limits of PCB so the total length of the graphics card with installed cooling system is 158 mm.

There is one big fan Apistek GA82S2L with a diameter of 76 mm, the blade is made of semi-transparent, blue plastic. Its main feature is the claimed low noise level (<28 dB).

HIS 7730 iCooler 1GB GDDR5 (H773F1G)

Aluminum radiator contacts only with GPU through a thin layer of thermal paste, while memory chips and support elements of the power subsystem don’t have of any additional cooling.

HIS 7730 iCooler 1GB GDDR5 (H773F1G)

During automatic speed control of the fan blades, rotation at the maximum load, the GPU was heated up to 66°C. The cooler rotated at a rate of 1,250 rpm, which corresponds to 46% of its maximum. Its operation was quiet.

HIS 7730 iCooler 1GB GDDR5 (H773F1G)

After the forced increase of blades rotational up to 100% (2150 rpm) the graphic processor temperature dropped on 10°C (56° C). At the same time the noise level was "below the average".

HIS 7730 iCooler 1GB GDDR5 (H773F1G)

In idle mode frequency of the GPU was automatically decreased to 300 MHz, and memory to 150 MHz. In this state the GPU temperature did not exceed 35°C, and the noise of cooling system was almost indistinguishable compared to other system components.
