There seems to be a single-slot ATI Radeon HD 5700 series trend going on, with XFX designing two single-slot ATI Radeon HD 5770 graphics cards, a base model (HD-577X-ZMF3), and an Eyefinity-5 model (HD-577X-Z5F3). Both cards use PCB and cooler designed by XFX. The cooler particularly looks familiar in design to the countless single-slot GeForce graphics cards designed by the company, one of the recent ones being a GeForce 9800 GT. The cooler makes generous use of copper.

Both cards stick to the reference AMD clock speeds, 850 MHz core and 1200 MHz (4800 MHz effective) memory, and feature 1 GB of GDDR5 memory across a 128-bit wide memory interface. Power is taken in from a single 6-pin PCI-E input. While the base model has display outputs which includes two DVI and one mini-DisplayPort, the Eyefinity-5 model features five mini-DisplayPort connectors. The cards will be released around the middle of this month, and Japan prices (which tend to be higher than US/EU prices) indicate 17,500 JPY (US $202) for the base model, and 18,000 JPY ($208).
