sapphire unveils hd 5770 vapor-x
sapphire expanded its radeon hd 5700 series with the sapphire hd 5770 vapor-x. This release comes around a month after the hd 5750 vapor-x, and resembles it in having the same gpu cooler: A gpu contact block with a vapor chamber acts as a large heatpipe, uniformly conveying heat to the heatsink above it, which is cooled by a fan. Unlike the hd 5750 vapor-x which comes with a blue reference pcb, this one retains the black reference one, with the cooler being the only noticeable change.

The radeon hd 5770 is based on the 40 nm juniper gpu. It is directx 11 compliant, and has 800 stream processors, along with 1 gb of memory installed across a 128-bit gddr5 interface. It also supports the ati eyefinity technology that allows users to scale a display head across three physical displays. Connectivity includes two dvi-d, and one each of hdmi and displayport. Sapphire also gave it a modest factory overclock, with the core running at 860 mhz (vs 850 mhz reference), while the memory stays at 1200 mhz (4.8 ghz effective). It is priced around 145 eur.
