The PCB itself is only 16.7 cm (6.6 inches) long. The bulky two heatpipe cooler extends past the edge of the card lengthwise by 2.5 cm (one inch). The card takes up two expansion slots and weighs 450 grams (about 1 lb), with the heatsink accounting for 310 grams. The Sapphire HD 7750 Ultimate has a hefty, impressively-sized fanless heatsink.

Included with the card is a manual, a driver disc, a DVI to VGA adapter, and, surprisingly, an HDMI cable (note: the HDMI cable not listed in the specifications). The video card itself is well protected in a thick foam compartment. The blue exterior is simply a cover, hiding a second plain cardboard box holding the package contents. Though the name suggests it is a replacement for the HD 5750, the current street price positions it above the HD 5770 despite slightly lower clock/memory speeds and 36% fewer shader units, which are critical for performance. With these improvements comes a drastically lower TDP with the HD 7750 rated for only 55W. The HD 77 are based around the new GCN (Graphics Core Next) architecture, packing 44% more transistors into a die 74% of the size of its HD 5000/6000 predecessors thanks in part to the substantial conversion from a 40 nm to 28 nm manufacturing process. Obviously you could do this with an aftermarket cooler to replace a stock fanned one, but it is probably not worthwhile: The HD 7750 is currently selling for about US$125, only $15 more than the various actively-cooled versions of the same card. The HD 7750 Ultimate has the same specifications as the reference design, including the scant 55W TDP, so it shouldn’t take a lot to cool without a fan. Back then, they simply slapped on Zalman’s famous VGA heatpipe cooler, but today they design their own passive cooling solutions.

Sapphire has been making Ultimate edition fanless graphics cards for a long time, going back all the way to the Radeon 9000 series in 2003. The lower-end GPU boasts very modest power draw, allowing Sapphire to produce a completely fanless version, the HD 7750 Ultimate, which is the subject of this review. More mainstream cards followed in the wake of this applause - like the US$110 HD 7750, pitiful by comparison to the early high-end releases, but a piece of hardware that will ultimately find its way into many more systems. As with previous generations, the top models were released first, the US$449 HD 7950 and US$549 HD 7970, to garner positive press for mind-blowing high resolution and multi-monitor gaming performance. XFX’s DD Radeon 7750 runs at reference clocks, as the GPUz screenshot below confirms.A few months ago, AMD launched the HD 7000 series of graphics cards to much fanfare. Note that the HD 7750 comes without an external power connector. According to the specs, HD 7770 cards have a TDP of 80W while HD 7750's TDP is 55w. HD 7750 cards have 32 texture units but the number of ROPs and the memory interface are identical to the HD 7770. The 1GB of GDDR5 memory runs on 128-bit memory interface. HD 7770 cards have 40 texture units and 16 ROPs.

Compared to the Tahiti's 1792 cores, Cape Verde XT (HD 7770) has only 640 while the PRO version of the chip (HD 7750) comes with 512 cores. However, Cape Verde is a smaller chip will less capabilities. The HD 7700 series belongs to Southern Island family, which is the first GPU family with GPUs made in 28 nanometer silicon fabrication processes, first to use PCI Express 3.0 x16 bus, and first with DirectX 11.1 support.Ĭards from the HD 7700 series run on Cape Verde GPU, which is related to the HD 7900 series' GPU called Tahiti. Note that this GPU is clocked slower than the Cape Verde XT, and we hope that the cooling won't be a limiting factor when it comes to additional overclocking. We're quite sure that the same cooler will have no trouble cooling the Cape Verde Pro GPU on our HD 7750. We know that the DD cooler is effective and quiet, since we had it on our Black Super OC DD Radeon 7770 1120M 1GB graphics card that runs at 1120MHz. However, we must commend XFX on strapping its Radeon 7750 with DD cooling. 800MHz for the GPU and 1125MHz for the memory (4500MHz GDDR5).ĪMD showed the reference design of its HD 7750s but all the cards we've seen thus far at least got their cooling changed. The DD Radeon 7750 800M 1GB runs at reference clocks, i.e. As you'd suggest, the DD in the name stands for Double Dissipation cooler design. Our today's guest is XFX's DD Radeon 7750 800M 1GB (FX-775A-ZDFC) graphics card that's special for its special dual fan design. We're talking about graphics cards with next generation chips with the so called GCM Graphics Core Next architecture, which promise to deliver improved performance at a lower power cost. On 13th of February, AMD launched its HD 7000 series of cards - or HD 7770 and HD 7750 to be more precise. Review: With silent and powerfull Double Dissipation cooler
