DirectX 11 and the Radeon 5000 series have finally hit the mainstream market in the form
of the Radeon HD 5670 graphics card. Priced at a mainstream $99 USD ($110 CDN / £65GBP), it's the most affordable way to experience DirectX11 hardware features like hardware
tessellation and compute shaders.
designed a slightly overclocked (+10MHz) version of the Radeon HD 5670 videocard called the GV-567OC-1GI.
ATI has produced several 'sweet spot' videocards over the past year like the
Radeon HD 4870, 4850 and 4770, and through aggressive pricing and new
manufacturing techniques ATI has managed to get all of these videocards into that
$100-$150 'sweet spot' that net excellent gaming performance at a cut-rate price.
Will the GV-567OC-1GI be worthy to join such hallowed company?
off with the heart of the Gigabyte GV-567OC-1GI PCI Express 2.0 x16
videocard, the Radeon HD 5670 GPU. Code-named "Redwood", it's based on the same "Evergreen"
architecture that powers the rest of the Radeon 5000-series graphics cards, including the flagship Radeon
5870. Gigabyte's GV-567OC-1GI videocard is thus blessed with 40 stream processors and a core
clock of 785MHz (the default speed is 775MHz, but Gigabyte kicks it
up a tiny bit).
This CrossFire capable videocard packs
1GB of GDDR5 memory with a fightin' 1000MHz clock, although due to GDDR5 quad-pumping the
effective speed is actually 4000MHz. The GPU communicates with this memory using a 128-bit wide
interface. No PCI Express power connector is required for this videocard, and
thanks to the march of time HDMI output is standard along with
DVI and Analog VGA.

Gigabyte's GV-567OC-1GI videocard operates over
a PCI Express
2.0 x16 link, although it also has natural backwards compatibility with PCI Express
1.0 and PCI Express 2.1. With a TDP of just 61W, the Radeon HD 5670
GV-567OC-1GI videocard doesn't require a separate PCI Express power adapter, and can
be run solely off the PCI Express bus' power.
Gigabyte equips the GV-567OC-1GI with HDMI, VGA and DVI outputs.
Since the Radeon HD 3000 series, ATI videocards have supported HDMI audio output
as well, which makes them ideal home theatre companions. This videocard is no
different, supporting 1080p HDMI output with audio, as well as 2560x1600 video
output over DVI and 2048x1536 using VGA.
The Gigabyte GV-567OC-1GI is equipped with a large and
fairly quiet aluminum heatsink, with a fan and plastic shroud on top. The
additional height of the heatsink means the GV-567OC-1GI videocard will occupy
two expansion slots instead of just one. Under testing the fan made an audible
hum at full speed, but was practically silent when set to run automatically.
Like most ATI Radeon videocards, the Gigabyte GV-567OC-1GI videocard
has a bi-directional Crossfire link for connecting to another Radeon
HD 5670 VGA. Setting up and enabling Crossfire is as easy as
installing the videocards into the PCI Express x16 motherboard slots and
connecting them with Crossfire bridge connectors (usually included with the
motherboard, check the box). Then all you have to do is install the AMD Catalyst
control center, hit the 'enable Crossfire X' option and you should be able to
enjoy dual-GPU processing - simple!
