XFX Radeon HD 5770 Video Card Review

Introduction

Radeon HD 5700 series is the first mid-range DirectX 11 video cards to arrive on the market. Let’snow  see the performance of Radeon HD 5770 from XFX and see if it is a good buy.

Radeon HD 5770 runs internally at 850 MHz and features 800 processors – the same amount found on Radeon HD 4850 and Radeon HD 4870 –, accessing its memory through a 128-bit interface, which is half the width found on Radeon HD 4850 and Radeon HD 4870. Radeon HD 5770, like  Radeon HD 4870 and members from Radeon HD 5800 family, uses GDDR5 memory chips, which are capable of transferring four data per clock cycle instead of just two. This makes the memories, which are accessed at 1.2 GHz, to achieve a performance as if they were accessed at 4.8 GHz, providing a 76.8 GB/s maximum theoretical transfer rate. To compare these specs to other graphics chips please take a look at our AMD ATI Chips Comparison Table and NVIDIA Chips Comparison Table.

The main competitor to Radeon HD 5770 is GeForce GTX 260 with 216 cores (“GeForce GTX 260/216”). In our review we will be mainly comparing the performance from these two video cards. We also included in our review Radeon HD 4850 and Radeon HD 4870, plus the new Radeon HD 5750 and GeForce GTS 250, and we should come up with a very interesting comparison.

Now let’s talk specifically about the Radeon HD 5770 from XFX. As you may be aware, XFX – which, by the way, many years ago was known as “Pine” – was for years one of the leading NVIDIA partners, and a while ago they decided they shouldn’t manufacture only NVIDIA-based video cards.

This model, also known as HD-577A-ZNFC, comes with 1 GB, two DVI outputs, one HDMI output and one DisplayPort output, following the reference model from AMD. This video card allows you to use up to three video monitors at the same time as a single desktop, feature known as “Eyefinity.” But there is a catch: the third monitor must use the DisplayPort connector, which is still not popular.
