We review the HIS Radeon HD 7970 X Turbo edition. With this card they took the new Tahiti XT2 and redesigned the R7970 board from ground up. though very long the end result is a 31cm PCB with mane power phases and optimizations. Fun to see are the voltage and FAN monitor LED options. Most impressive however is the sheer amount of monitor connectors HIS injected into this product, four DisplayPort connectors, one HDMI and a DVI connector. If needed you can go for Eyefinity6. Oh did I mention already that the factory set boost clock frequency is 1180 Mhz ?

AMD releases an update to the Radeon HD 7950, as they have given it Boost functionality. The boost functionality itself and the core is now allowed to boost to 925 MHz. That means that under the right conditions the card gets a bump of 5 to 10% performance according out measurements. Will it make a big enough difference to compete with the new GeForce GTX 660 Ti ?

Club3D jumped the 7800 bandwagon as well with several models, and for this review we'll be looking at their Radeon HD 7850 Royal Queen edition which comes with 1 GB of graphics memory. The product comes default in many ways, except the cooler. Club3D uses a small PCB and pretty slim dual-slot cooler making the card very easy to install. The graphics card is equipped with one 6-pin PCIe power connector. As mentioned the card comes default/reference clocked at 860 MHz and the memory is clocked at a 4800 MHz reference as well.

We review the MSI Radeon HD 7770 Power Edition. MSI recently released an updated Radeon HD 7770 1GHz edition with their own 1.1 GHz custom model. They use their own custom 4-layer PCB and equipped it with a dual cooling solution. I say dual here as you get an extra fan that you can pop onto the card for extra cooling. MSI also opened up the voltages for Aux, GPU and memory making the card very tweakable.

We review the HIS Radeon HD 7950 IceQX Turbo. The product comes factory overclocked very nicely for you as it is running a gentle 900 MHz clock frequency. HIS uses a custom PCB and dual-slot cooler making the card very easy to install. Despite that factory overclock and that cooler the noise levels remain at very low levels whereas the GPU temperatures remain downright excellent as we'll show you in this review.

We review the new Radeon HD 7970 GHz edition. The product is called GHz edition though even a little more. AMD now uses a Boost feature, exactly similar to what NVIDIA is doing on the 670/680 cards. The R7970 Ghz edition can 'boost' from 1000 MHz towards 1050 MHz if it meets the right conditions. So the board power (maximum power draw) needs to allow it to do so, if not it drops to 1 GHz or whatever board power range is allowed. Not only have there been tweaks on the GPU, no the memory clocks got overhauled as well and have been increased from 5,5 Gbps towards 6 Gbps bringing the product a good chunk of additional memory bandwidth. Overall the new values should bring the product a nice 10 to 15% performance boost opposed to the regular model.

HIS jumped the 7800 bandwagon as well with several models, and for this review we'll be looking at their Radeon HD 7850 IceqX TurboX model. The product comes factory overclocked very nicely for you as it is running a precipitous 1 GHz clock frequency. HIS uses a small PCB and pretty slim dual-slot cooler making the card very easy to install. Despite that factory overclock and that cooler the noise levels remain at normal levels whereas the GPU temperatures remain downright excellent.

We review the MSI Radeon HD 7850 Power Edition OC with that all new TwinFrozr IV cooler. The updated cooler has much better looks and MSI’s proprietary TwinFrozr IV cooling system that packs 8mm thick nickel-plated copper heatpipes to convey heat drawn directly from the GPU to a large aluminum fin array, ventilated by two 80 mm fans. These fans are based on the new dust removal technology, which means that the 1st 30- seconds they'll spin backwards in an attempt to remove any residual dust that can build up over time.

We review the MSI Radeon HD 7970 Lightning. What a product to look at, the R7970 lightning has a very rare design, comes with only the best components, has voltage monitoring headers, comes pre-overclocked (extensively) and allows to be voltage tweaked at many levels. To pursue Eyefinity they have made the card Eyefinity6 compatible, by use of four DisplayPort connectors and two single link DVI connectors you can get six monitors running. Though realistically nobody does that as you have that ugly bezel from left to right smack down in the middle of you field of view. There's another feature though, to give the product a little more 'niche' MSI implemented a small add-on board that is called a GPU-reactor which functions as a power supply module which, when installed on the back of the GPU.

We test the Gigabyte Radeon HD 7970 OC (WindForce) edition. It's a fully fetched R7970 on a customized PCB, it comes factory overclocked for you and next to that they applied their popular WindForce cooler, the one that has a cool number of three active fans. The results are pretty impressive as you'll find out, that factory overclock is boils down to a default clock frequency of 1000 MHz on the GPU core. Next to that the WindForce cooler is able to keep the product under 65 Degrees C, and that's under full load and stress.

HIS decided to jump on the bandwagon and releases a slightly customized R7750, it's named the HIS 7750 iCooler 1GB. As you can tell from the photo below the card is all customized, a nice blue PCB and a cooler, that though eats two slots, makes the cards virtually silent. Much much better then the reference AMD design really. The card remains 100% reference clocked though at a price of give or take 99 USD it might give it enough bite for a game or two in the lower resolutions.
