Graphics card HIS R9 270 iPower IceQ X2 Boost Clock 2GB GDDR5 PCI-E DLDVI-I/HDMI/2xMini DP (H270QM2G2M): review and testing

Continuing the acquainted with the products of Hightech Information System Limited (HIS), which specializes in production of graphics cards based on graphics processors of AMD company. In this material we will describe a novelty HIS R9 270 iPower IceQ X² Boost Clock 2GB GDDR5 PCI-E DLDVI-I/HDMI/2xMini DP based on the popular graphic core AMD Radeon R9 270. Even after the appearance of energy-efficient microarchitecture NVIDIA Maxwell and graphics cards of series NVIDIA GeForce GTX 750 Ti, these solutions still look quite promising due to the good performance. And in the case of the new graphics accelerator from HIS company an important role plays the addition of a quiet and efficient proprietary cooling system IceQ X².

Supplied set of HIS R9 270 iPower IceQ X² Boost Clock includes:

  • adapter Dual-link DVI-I ↔ D-Sub;
  • bridge AMD CrossFireX;
  • sticker on the computer case;
  • CD with drivers and software;
  • quick start guide.  

This kit has almost everything you might need when building a computer. Here there is a bridge AMD CrossFireX to create a gaming configuration of two graphics cards, as well as the adapter Dual-link DVI-I ↔ D-Sub for analog monitors. The only accessory that may have to buy is the adapter for the 6-pin PCIe. It is necessary only if its is not present in your PSU.

To display an image the original set of interfaces is used:

  • 2 x Mini DisplayPort;
  • 1 x HDMI;
  • 1 x Dual-link DVI-I.

This configuration will easily connect almost any modern monitor or TV, especially taking into account the supplied adapter with socket D-Sub. It is also possible to simultaneously connect up to six monitors, but for this you have separately buy adapters for connectors Mini DisplayPort.

The following resolutions are supported:

  • Digital p to 4096 x 2160;
  • Analog up to 2048 x 1536.

Design and circuitry

HIS R9 270 iPower IceQ X2 Boost Clock (H270QM2G2M)

Graphics accelerator HIS H270QM2G2M is made on a blue textolite. The card is quite compact and its height is 112 mm. The graphics chip is equipped with a protective frame to protect it from chips and scratches when removing and installing the cooling system.

The graphics card is equipped with a reinforced 7-phase power subsystem, five phases for GPU and one for PLL and one for memory chips. It is one GPU phase more in comparison with reference option. At the same time it uses high-quality chips RENESAS 20658 with design Dr.MOS, which are designed to operate at temperatures up to 97°C. Also, here are installed reliable solid-state capacitors, designed for operation at high load.

Chip CHiL CHL8225G is used as the controller. It has the function of dynamic phase disconnection to save energy at low load.

In addition to slot PCI Express 3.0 x16, one 6-pin PCIe is also used for power supplying. It should be noted that the plastic casing of the cooling system makes it difficult to connect and disconnect the connector.

To join the two graphics cards using AMD CrossFireX technology there is a connector for the appropriate bridge, which is located next to the interface panel. Due to the combining of the computing capabilities of graphics accelerators the compatible games can achieve significant performance gains.

The manufacturer did not make any major functional elements on the opposite side of the PCB, so you can only see the four screws that secure the cooling system, and a couple of labels with technical information.

Graphics card HIS R9 270 iPower IceQ X² Boost Clock is based on the graphic chip AMD Curacao PRO, which is made by a 28-nm technology process. It consists of 1280 unified shader pipelines, 80 texture units and 32 Rops. The graphics core runs at a nominal frequency of 900 MHz, which is dynamically increased up to 925 MHz, which is fully consistent with the standard scheme of functioning.

HIS R9 270 iPower IceQ X2 Boost Clock (H270QM2G2M)

Memory capacity is 2 GB which is collected by using 8 chips SK Hynix H5GQ2H24AFR with capacity 256 MB each. Effective working memory frequency is at 5600 MHz, and the exchange of data with graphics chip is realized via 256-bit bus the capacity of which is equal to 179.2 GB/s.

Cooling system

HIS R9 270 iPower IceQ X2 Boost Clock (H270QM2G2M)

Graphics accelerator is equipped with proprietary dual-slot cooling system IceQ X², which has a length of 224 mm and a height of 112 mm (as measured in our lab). On top of it is covered with a protective plastic cover. Based on its construction, part of the hot air dissipated by the fan will fall inside the computer chassis, thus will have a little effect to the temperature of other components of the system.

Functions of blowing are performed by two fans Apistek GA81B2U with blade diameter of 75 mm. According to the manufacturer, they have a fairly long life (up to 50,000 hours).

The radiator collected from 34 nickel-plated aluminum fins is used to dissipate the heat. Heat removal is carried out sufficiently by large copper plate (62 x 62 mm) which contacts with graphics processor via a thin layer of thermal paste and three 6-mm copper heat pipes.

Heat pipes are not covered by a layer of nickel, so their heat conducting properties may become worse during operation as a result of oxidation. On the other hand, they are securely soldered to the edges of the radiator and melted to the copper base, which should improve the efficiency of the whole system.

In the automatic control mode of fan speed, at maximum load, the GPU was heated up to 59°C. At the same time the fans were operated at the level of 39% (1978 rpm) of its maximum speed. Their operation was quiet.

After the forced rotation of fans at the maximum speed (3859 rpm) the core temperature is dropped to 49°C. The level of noise was rose to "above average", and it was uncomfortable for long-term work at the computer. In most cases, this mode is only useful when performing acceleration or for load testing.

HIS R9 270 iPower IceQ X2 Boost Clock (H270QM2G2M)

After the transition to idle speed the GPU frequency was automatically decreased to 300 MHz and a temperature to 31°C. The noise from the propellers work at a speed of 1354 rpm was virtually indistinguishable on the background of other components.
