It is not unusual nowadays to see a graphics card with passive cooler. Sapphire release such graphics cards in their series of Ultimate edition fanless graphics cards. Despite the fact that these models do not have a great computing power, they are perfectly able to cope with their responsibilities in multimedia computers. Their main advantage it's quiet operation. A quiet operation is important for any computer, especially for an HTPC. After all, nobody wants to watch a movie with a noisy graphics card cooler fan.
Today we are going to take a look at the new graphics card from Sapphire - the Radeon HD7750 Ultimate. Sapphire HD 7750 Ultimate graphics card have 1Gb of GDDR5 memory in the form of four memory chips. Each pair of chips is covered with a special black strip specialy designed for heat removal. The GPU used Sapphire's Radeon HD7750 Ultimate in code named Cape Verde and it is produced on 28nm process. It is located in the center of the PCB. The GPU core frequency of this graphics card is 800MHz, and memory operates at 4500Mhz (4 x 1125MHz). The full specifications can be found here.
We were able to oveclock the GPU core frequency of Sapphire HD 7750 Ultimate graphics card to 879MHz, which is about 10% increase over the default GPU clock. Also, we overclocked the Memory to 1250MHz which is more than 11% increase memory frequency.
Despite the fact that the Sapphire HD7750 Ultimate graphics card has no fan, the core temperature under full load manages to retain a decent level (162°F/72°C). Thus, the HD 7750 Ultimate is quite easy to recommend to those who intend to build a multi-media class computer. If you decide to play the latest games using this graphics card, then this can be done at 1680x1050 resolution on high settings, or 1920x1080 with picture quality set to medium level.
Conclusion
Sapphire produced an excellent graphics card for anyone who wants to build a quiet multimedia PC. Also, it is a solid graphics card for someone who's looking to do some casual gaming.
