MSI announced a pair of Radeon HD 7970 graphics cards which feature PowerTune with Boost, yet aren't based on the HD 7970 GHz Edition chip. The company labeled these cards simply "HD 7970 Boost Edition." Among the cards MSI unveiled are a base-model (R7970 TF 3GD5 BE), and a factory-overclocked one (R7970 TF 3GD5 BE/OC). The base model features a GPU clock speed of 925 MHz, PowerTune Boost clock speed of 975 MHz, and memory speed of 5.50 GHz. The OC variant, on the other hand, features a GPU clock speed of 1000 MHz, Boost clock of 1050 MHz, and memory clock of the same 5.50 GHz. Hence neither conform to AMD's HD 7970 GHz Edition specs. Both cards are based on custom designed PCBs and cooling solutions, by MSI. Its trusty Twin Frozr III cooling solution, which uses a pair of 80 mm "Propeller Blade" (high sweep) fans to ventilate a dense heatpipe-fed aluminum fin stack; is in charge of cooling the GPU, while a heatspreader looks after the memory and VRM. TDP of both cards is rated at 253W, both cards draw power from a combination of 8-pin and 6-pin PCIe power connectors. Display outputs on both cards include a dual-link DVI, an HDMI 1.4a, and two mini-DisplayPort 1.2 connectors. MSI did not reveal pricing.
