Introduction

A while back AMD has quietly launched their HD 3400 and HD 3600 Series. The cards are based on the RV620 and RV635 GPUs which are a refresh of the RV610 and RV630. The major features they introduce are support for PCI-Express 2.0 and a transition from a 65nm to a 55 nm manufacturing process. Both feature AMD's UVD for accelerated video decoding and integrated HDCP+Audio support for media PC systems.

The Diamond HD 3650 is one of the first HD3650 cards to feature 1 GB of video memory. Please note that this is DDR2 which is a bit aged already, but probably came at a great price for Diamond so they wouldn't let the opportunity pass.

Packaging & Contents

The grey/silver package with Ruby on the front looks extremely stylish. A small window adds to the visual appearance of the box. On the back you find more detailed product information in English and French. The big xDna lettering states that this card supports CrossFire on any chipset including NVIDIA platforms. This is a technology exclusively available from Diamond Multimedia (so far).



You will receive:

• Graphics card
• DVI Adapter

The Card

Diamond's HD 3650 has a simple design compared to the complexity of today's high-end cards. The cooler is rather small and covers only four of the eight memory chips. As expected the card has a single slot design because the heat output of ATI's RV635 GPU is really low.
Even though a physical CrossFire connector is not present, this card supports CrossFire via the PCI-Express bus which is fully adequate given the performance of the GPU. You can also run three or four of these cards in CrossFireX, even on NVIDIA chipsets using Diamond's exclusive xDNA technology.


The card has one analog VGA, one DVI and one HDMI port. This is a great combination covering all possible aspects of this card's use. In case you need a second analog VGA port you can use the included DVI adapter. The HDMI port supports HDMI+HDCP+Audio, which allows easy setup of a media PC.


Here are the front and the back of the card, high-res versions are also available (front, back). If you choose to use these images for voltmods etc, please include a link back to this site or let us post your article.
