We review the ASUS Radeon HD 7970 DirectCU II. A factory overclocked three slot wide beast with massive cooling capacity. The completely customized card comes with voltage measurement points, a 12-phase VRM circuitry with supper alloy caps and chokes as well as a special SAP capacitor added to maximize overclocking headroom, according to ASUS.

This is a Radeon HD 7870 Overclock Guide. We'll overclock based on a mild voltage tweak. By doing so we drive the R7870 into R7900 series performance. All you need is some free software and a little time to precisely determine and pinpoint your maximum yet stable overclock.

We review the AMD Radeon HD 7850 and 7870. These two new mid-range cards are going to shift the dynamics in the graphics arena alright, as the entire package including performance is really impressive for the 7800 series. A product series that is to replace the 6800-series performance-wise, it is based on AMD's 28nm process and of course the latest Graphics Core Next GPU architecture.

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.

It's now February 2012 and AMD thinks they have a new '5770' in their hands. The codename is 'Cape Verde' for the GPU, and the graphics cards deriving from them are the Radeon HD 7750 and 7770 One GHz edition. This is not a refresh it is a completely new GPU based on the same technology that powers the R7900 series, the GCN architecture. Head on over to the next page where we'll meet and greet Cape Verde, aka Radeon HD series 7700.

MSI joins in on the Radeon HD 7770 release with their own custom model. They use their own custom 4-layer PCB and equipped it with a dual slot - dual fan cooler. The end result is the R7770 2PMD1GD5, we test the OC edition model. Over the next few pages we'll walk through three standard reference technology and then place our focus on the R7770 2PMD1GD5 OC. But not before you have had a peek alright.

MSI is added in our line-up of R7950 reviews with a customized model. It is the TwinFrozr III version that clocks in at a nice 880 MHz on the graphics core with it's memory clocked default at an effective data rate of 5000 MHZ. It is locked and loaded with 3GB of graphics memory and dressed to impress.

We take a Radeon HD 7950 overclock it the normal way and then voltage tweaked. So that way we will demonstrate not one, but two maximum overclock conditions alongside TDP, heat, noise and performance levels.

It is time for the second product based of the series 7900 though, the Radeon HD 7950 launches today. AMD took the Tahiti XT GPU sliced away some shader units, clocked it a notch slower and planted it onto a new PCB lined up with a new cooler. Overall the R7950 will not disappoint, good performance, impressive power consumption and great heat and noise levels. But will a 400 EUR pricetag however justify this product ?

PowerColor is the first in our line-up of R7950 reviews with a customized model. It is the PCS version that clocks in at a cool 880 MHz on the graphics core with it's memory clocked default at an effective data rate of 5000 MHZ. Armed witha custom cooler it is silent, and even cooler compared to the reference model.

We review the Radeon HD 7970. Injected in the 499 EUR / 549 USD price tag bracket the product will have to compete directly with the equally expensive GeForce GTX 580, it will actually be a decent notch better then that IMHO. The results that you'll witness today will not dishearten. Where it matters (the latest and newer games) the Radeon HD 7970 will be a good 20%, 30% sometimes even 40% faster then the competition, and in the world of enthusiast graphics performance that's what we call, a product with a little extra booty.

The card comes with a triple over-voltage function which supports voltage adjustment of GPU, memory & VDDCI. And the power indication hints towards a P/S Switch Function where two fan speed profiles (Performance / Silence) can be configured. The product will get that new GPU seated into a custom PCB and will be cooled by that lovely TwinFrozr III cooler.
