Our other editorials today focus on the new AMD HD7770 1GHZ graphics card, which is the higher end model in the 77xx range. In this review however we look at the HIS HD7750, a card which aims to target the budget aware gaming audience.
HIS haven't quite yet earned the reputation of Sapphire or XFX in the high end sector, although we have positively rated their IceQ coolers over the last year. How will they tackle this modestly priced budget solution?
Their HD7750 graphics card features a proprietary cooler with the ‘iCooler' moniker. Clearly someone in the company is an Apple lover.
Above the HIS HD7750 next to the reference AMD HD7750 solution.
This iCooler isn't a dramatic overhaul of the reference AMD design, however HIS have opted for a larger fan which in theory should offer lower noise emissions and superior cooling efficiency at the same speeds.

The HD7750 is built on the latest 28nm manufacturing process, but it is clocked at 800mhz, which is 200mhz slower than the more expensive HD7770. The card has 512 stream processors, down from 640 on the HD7770 and 32 texture units, down from 40 texture units on the HD7770.
What an insanely dull card from AMD. not much HIS could do to make this interesting. but why not focus on a single slot cooler for HTPC? would have been ideal, right?
