Introduction

HIS Logo


AMD's new Radeon R9 270X draws its lineage more from the Radeon HD 7800 series than any other. The R9 270X is, for all intents and purposes, identical to the Radeon HD 7870 GHz Edition which launched at $350, but settled down to around $250, holding on to that price-point quite well, and for quite long. At 1050 MHz, its GPU core clock speed is 5 percent higher, and at 1400 MHz (5.60 GT/s effective), its memory clock speed is a significant 16 percent higher than the HD 7870.

The 28 nm "Pitcairn" silicon on which the Radeon R9 270X is based features 1,280 stream processors based on the Graphics CoreNext micro-architecture, 80 texture memory units (TMUs), 32 raster operations units (ROPs), and a 256-bit wide GDDR5 memory interface holding 2 GB of memory.



The R9 270X reviewed today comes from HIS. They have increased clock speeds significantly on their R9 270X IceQ X² Turbo Boost, making this one of the highest-clocked R9 270Xs on the market at this time. We also find the HIS signature IceQ X cooler with its two fans on the card.

The card is very competitive in terms of pricing as it is available online for $200, which means there is no price increase at all for higher clocks and the cooler.

Packaging

We received the card without packaging or accessories from AMD. Rest assured that the final product will come with the usual documentation, driver CD, and adapters.

The Card

Graphics Card Front
Graphics Card Back

HIS has been using this cooler on other models before, so there shouldn't be any surprises. Dimensions of the card are 26.5 x 12.5 cm.

Graphics Card Height

Installation requires two slots in your system.

Monitor Outputs, Display Connectors

Display connectivity options include one DVI port, one HDMI port, and two Mini-DisplayPorts. You may use all outputs at the same time, so triple-monitor surround gaming is possible with one card.

The GPU also includes an HDMI sound device. It is HDMI 1.4a compatible, which includes HD audio and Blu-ray 3D movies support.


One CrossFire connector allows you to combine up to two R9 270X cards in a CrossFire configuration.

A Closer Look

Graphics Card Cooler Front
Graphics Card Cooler Back

Five heatpipes on the heatsink and a copper base move heat quickly from the GPU surface to the fins, where it is dissipated in the fans' airflow.


A small metal plate sits below the cooler and cools secondary components like memory chips and voltage regulation circuitry.

Graphics Card Power Plugs

The card requires two 6-pin PCI-Express power connectors. This configuration is good for up to 225 W of power draw.


HIS uses a CHiL CHL8225G, a very common and popular voltage controller that offers software voltage control and monitoring. It is also well-supported by most software.

Graphics Card Memory Chips

The GDDR5 memory chips are made by Elpida and carry the model number W2032BBBG-6A-F. They are specified to run at 1500 MHz (6000 MHz GDDR5 effective).

Graphics Chip GPU

AMD's Pitcairn graphics processor uses the GCN shader architecture. It is produced on a 28 nm process at TSMC. The transistor count is 2.8 billion.
