New ATI Radeon HD 5700 GPUs

After the pompous launch of ATI Radeon HD 5800 series graphics cards, AMD has quietly launched new Radeon HD 5700 graphics cards. ATI Radeon HD 5770 and HD 5750 join the family of DirectX 11 supporting cards usable with Windows 7 launching by month end. Built from 40nm GPU chip, the new Radeon HD 5770 is meant for mainstream segment and will compete with Nvidia GTX 260 graphics card.

AMD's new ATI Radeon HD 5700 graphics cards for mainstream is dubbed as Juniper. In this Radeon HD 5700 series family, Juniper XT HD 5770 is codenamed as Countach and Juniper LE HD 5750 is codenamed as Corvette. Both graphics cards possess same features as that of Radeon HD 5800 series Cypress cards - 40nm GPU, multi-monitor Eyefinity Technology, ATI Stream technology, Unified Video Decoder 2.0 and expected to be more "affordable" than the former series.

Last week, an image of Radeon HD 5770 was scooped from the web. As per official specifications, ATI Radeon HD 5770has 800 stream processors which are as much as in HD 4870 GPU. Even the number of texture units (40 texture units) is the same between HD 5770 and HD 4870. The difference lies in the transistor count where HD 5770 scores with 1.04 billion transistors while HD 4870 has 956 million transistors.

Not to forget, HD 4870 comes from 55nm fabrication process with Thermal Design Power rating of 150W. On the other hand, HD 5770 comes from 40nm fabrication process output with TDP rating of 108W only. ATI's Radeon HD 5770 graphics chip has core clocked at 850MHz and 1GB GDDR5 memory clocked at 1.2GHz promising 4.8GHz data rate over 128-bit memory bus interface.

HD 5750 manages with 720 stream processors and 36 texture units has graphics core clocked at 700MHz. With an option of 512MB/1GB GDDR5 memory clocked at 1.15GHz, again 128-bit memory bus interface is present here. Note that Radeon HD 5870 and HD 5850 have 256-bit memory bus interface. Not surprisingly, Radeon HD 5750 has Thermal Design Power rating of 86W and would prove to be a power efficient and budget friendly DirectX 11 card.

Both cards support multi-GPU CrossFireX technology and ATI Avivo HD Video and Display technology. These cards an easily stream 1080p HD content and have HDMI out with dual-link DVI ports and DisplayPort to support the Eyefinity Multimonitor technology.

ATI Radeon HD 5000 family of graphics cards bring along loads of features. Eyefinity multi-monitor technology, Stream technology, UVD 2.0, OpenGL 3.2 support and most important DirectX 11 support are few of the many new things in this new family of graphics cards. Radeon HD 5000 family is the first to enable the Dolby TrueHD and DTS-HD MA (bitstream audio) offered by select Blu-ray titles.

Radeon HD 5770 is priced at $159 (Rs. 7,680 approx.) and HD 5750 1GB costs $129 (Rs. 6,240 approx.) while 512MB will cost you $109 (Rs. 5,300 approx.).
