(TS) – 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.

With 800 Stream processors and 1GB of the latest DDR5 memory, together with enhanced clock speeds of 860MHz core and 1200MHz (4.8GHz effective) for the memory, the SAPPHIRE HD 5770 Vapor-X model is the fastest card in its class. SAPPHIRE’s World leading Vapor-X technology not only allows the card to run quieter than the standard model, it runs 9ºC cooler than the reference design and provides additional headroom for performance tuning (overclocking).
