Both the HD 5770 and HD 5750 were released globally this morning, and our very own Michael “SKYMTL” Hoenig has done an excellent work up on both cards, including a overclocking special by Asus:
The cards are the first of the 40nm Juniper lineup, boasting an impressive 1.04 billion transistors and come in a 512MB or 1GB GDDR5 variant with 128-bit memory bus. The HD 5770 is the premier model with 800 stream processors and clock speeds of 800MHz core and 1200MHz memory. The HD 5750 features 720 stream processors and clocks speeds of 700MHz core and 1150MHz memory. Both cards have impressively low power consumption, being claimed at a max of 18W idle and a 108w at full load.
For comparison’s sake, the Radeon HD 4890 released in April’ 09 and based on the R700 chip, only features 956 million transistors, 800 shaders and core/memory speeds of 850MHz/975MHz.
ATI has also include their new Eyefinity technology for both cards, making them a great low cost solution for users simply want to utilize this feature. The cards will allow for connection of three monitors of up to a 2560×1600 resolution, stitching them into a single display.
The cards are currently available on many retailer shelves for a price of $159 USD for the HD 5770 and $129 or $109 for the HD 5750 1GB and 512MB versions respectively.
