It is no secret that cards with power dissipations below the 100-watt limit can already be cooled well passively. If you then move close to the 50 watt limit, things get really interesting. No matter if in a free setup or in a tight case, this small amount of waste heat should actually be manageable with aplomb. That’s exactly what I wrote 11 years ago to the day. So today, let’s jump back to 2012. Have fun remembering 🙂
It is a logical conclusion that the Radeon HD 7750 with its maximum of 50 watts of waste heat is begging to be cooled passively. Thus, it was only a matter of time until the first passively cooled offshoot of AMD’s very frugal Cape Verde chip reached the stores of this world. Sapphire has made the best use of the time between the launch of the chips and today, introducing the HD 7750 Ultimate, the first passive card with the new 28nm GCN architecture. Thus, the card has not only made it to CeBIT and into many news of the last few days, but also already into our test lab, where we have already tested this new card thoroughly and quite exclusively.
In addition to the technical features of the new 77 series, the card even promises a quite appealing gaming performance in the living room at home with very moderate power consumption and a cooling that is easy to control. We have tested the card in various situations under load, will also deal with the most important rules for successful installation and operation in this article, and of course offer the appropriate benchmarks. HTPC, media center or silent PC in the upper entry-level class – the goal is clear, but the results had yet to confirm the very high expectations in the run-up.
Packaging and scope of delivery
Sapphire ships the card along with a 1.8 meter HDMI cable, as well as a DVI-to-VGA adapter. You’ll also find a driver CD and a thin manual. From a purely environmental point of view, the foam insert in the inner packaging could certainly have been dispensed with, since Sapphire has also done without it before. The rest is usual standard and stable enough.
Design and connections
Back to the included HDMI cable. HDMI execution has been improved on the HD-7000 series, supporting Fast HDMI 1.4a stereoscopic 3D at frame rates of 60 Hz per eye, for a total refresh rate of 120 Hz. Besides the HDMI port (1.4a) with 3 GHz and the DisplayPort 1.2 HBR, which both allow connecting extremely high-resolution displays, the user will also find a DVI port, which additionally provides an analog signal via adapters.
The used cooling solution of heatsink and heatpipes is well equipped for the maximum of 50-55 watts of waste heat, but you have to keep in mind that the back of the card is also covered by a part of the heat sink besides the higher installation height of 12 cm.
It is important that the distance between the card and the CPU cooler shrinks to a minimum when the PCIe x16 on the motherboard is the first slot. On the other hand, when selecting a board, it should be noted that an overlying PCIe1 x1 alternative board is no longer suitable for accommodating full-height expansion cards after inserting the HD 7750 Ultimate, because the rear part of the cooler is then in the way of these cards.
