HIS Radeon HD4770

Introduction

The Graphics Card market is one which has taken some real beatings in the past year with the economic crisis. Instead of blowing your pay cheque as soon as it lands in your hand, many people are being more cautious about their purchases, making sure it’s not money wasted and that you’ve got the best performance for your hard earned cash. This is great for review websites like us, but for ATI and Nvidia it’s a very different story. Instead of taking a step forward in developing a bigger, better and usually more expensive card, which is normally the case, they’ve taken a leap backwards to provide for the ever-increasing ‘budget market’.

One such graphics card from ATI to enter this market is the HD 4770. Although it’s not the newest of graphics cards on the block and by no means the fastest, for users who are looking to spend under £100 on a video card, its features and specifications mean it’s one of the top candidates when deciding what graphics card to purchase.

Today we have an ATI HD4770 to review from the popular company named HIS. HIS are one of the leading manufacturers of ATI graphics cards. To see how this budget monster performs, we’ll be comparing it to a card just £20 more expensive. Time to see how this RV740 GPU video card performs…

The Technology behind the card…

Whereas most graphics cards feature a 55nm GPU, the 4770 HD from ATI is built with a 40nm chip. The smaller manufacturing process used to create this GPU means that more transistors can be fitted inside the same sized piece of silicon. In fact, to be precise, the RV740 has 826 million in a 143mm chip whereas the RV770 55nm chip has 965 million in a 267mm chip. Quite some size difference! So what does all this mean? The main advantage is significantly reduced power consumption and greater clock speeds, it only takes 80W to power a 4770.

There’s an interesting entry which shows the benefits of increasing transistor count here.

CoolIT Domino i5 Testing

Back in July this year we tested the CoolIT watercooling kit using a heavily overclocked AMD 7750+ BE. It’s performance really surprised us with it absolutely caning the other coolers in question.

For this reason, we thought some i5 testing using our trusty CoolIT Domino was in order. Let’s see if the performance from the Domino still survives in this day and age…

Laptop technology has advanced greatly over the years with different releases of more powerful and compact systems constantly replacing the top notebooks of the year before. However, improving the performance of laptops usually has the knock on effect of producing more heat and so users will commonly seek advice in order to better cool their laptop. An often used approach to this problem is a Laptop Cooler.

However, most laptop coolers do more than simply draw hot air from your system. Many laptop coolers also have become a key feature in making the experience of using a portable machine at a desk more comfortable overall.
