AMD Radeon HD 7770 - Seizing the Day with Cape Verde, the ASUS Way

ASUS HD 7770 DirectCU TOP 1GB GDDR5 - An OC Offering

Breaking the 1000MHz Barrier

We have on our hands the ASUS Radeon HD 7770 DirectCU TOP 1GB GDDR5 (HD7770-DCT-1GD5) that features an overclocked Cape Verde GPU. Its rated clock speed is 1120MHz which is 12% higher than the default suggested clock speed of 1000MHz. As such for this article, we'll be focusing only on the Radeon HD 7770 and its performance aspects as displayed by this ASUS graphics card.

With its DirectCU cooling technology, ASUS has clearly stated that its cooling technology is supposedly able to make the card 20% cooler against stock coolers. We'll have to verify that another day when we do get a reference card for comparison.


Keeping Things Cool

With its customized DirectCU cooling solution, it adds a touch of premium quality to the build of ASUS Radeon HD 7770. During our test of the card, its 40mm fan was noticeably quiet as it went about its business of keeping the GPU cool.

We have a top view of the card and we can see the twin 8mm DirectCU heatpipes that draw heat away from the overclocked Cape Verde GPU.

The heatpipes draw heat away from the DirectCU heatsink that sits directly on the Cape Verde GPU.


Up Close and Personal

On a cursory glance, the card bears a slight resemblance to ASUS EAH6850 DirectCU.The card measures 22.5cm in length when measured from the edge of its metal backplate to the rightmost edge of the plastic shielding of its heatsink.

Notice how the plastic shielding of its DirectCU heatsink extends slightly beyond the PCB of the graphics card.

For video output connectivity, the ASUS card has one DVI connector, a single HDMI port and two mini DisplayPorts.


Skin Deep Tweaks

Bundled with the card is the latest tweaking software is the ASUS GPU Tweak. With this nifty utility, you can tweak your card as well as update its drivers and BIOS for optimal performance.

 The ASUS GPUTweak is a useful utility for tweaking and managing your AMD Radeon 7000 series of cards. We have also used earlier versions of this software for other cards based on different GPUs.
