PowerColor Radeon HD 7950 PCS+ review

One of the biggest success stories of the Radeon series was the introduction of Eyefinity. Eyefinity allows you to use multiple monitors in desktop and gaming mode. Typically you needed the very same monitors and resolutions, Eyefinity 2.0 changes that. You are now actually able to create a custom resolution. So if you have three difference sized monitors, you can actually get that working (not that I'd recommend it) .
More monitor signal bandwidth is created with the 7900 series cards as well, you may now create resolutions of 16k x 16k. This for a fact allows you to setup say five screens in 5.1 Landscape mode in 1920x1200 and even 2560x1600 monitors.
You guys slowly start to understand now why the R7900 series has 3GB of graphics memory right, huge resolutions require huge framebuffers. And for the above mentioned setup with 2560x1600 monitors that would boil down towards 12800 x 1600 pixels, that's a 20 Mpixels resolution.
Later on, in the February 2012 release of AMD catalyst drivers, you will see support for the afore mentioned custom resolutions as well. So 3072x768 can be made manually as well as 5040x1050 or 5670x1200. You are in control of the resolution you like to apply to your monitors.
In the upcoming Catalyst 12.2 you will also see a new feature called taskbar positioning. Say that you setup 3 or even 5 screens in landscape mode. Then it's always a total bitch that the start menu and icons are located all the way to the far left screen. The new feature will allow you to configure the position of the taskbar, so if you want it positioned in the middle monitor, that will become an option. That's progress folks...
AMD's Radeon 7900 series cards will support DirectX 11.1 as the hardware is compatible. It's way too soon to even talk about it really, as DX 11.1 is due to be released alongside Windows 8.
New primary features in this update will be:
- Target independent rasterization
- Flexible interoperability between graphics compute and video
- Native Stereo 3D support
AMD's Unified Video Decoder
Inside each AMD Radeon GPU there's some separate core logic dedicated to video encoding and decoding. This is called the Unified Video Decoder. The Radeon 7900 series will see a small update to it. Obviously it will keep all the features it's predecessors had, however MVC (Multi-View Codec), MPEG-4 and DiVX are now supported in hardware. Also a small feature called Dual Stream HD+HD has been added.
We test and review the PowerColor Radeon HD 7790 TurboDuo OC edition incl FCAT Frametimes. The new graphics card is intended to boost a little more performance into entry-level gaming. The PowerColor TurboDuo HD7790 OC clocks at 7.5% overclocking speed on boost engine, packed with dual-fan cooling and S-shape heat pipe direct touch technology.
PowerColor Radeon HD 7950 PCS+ review
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.
PowerColor Radeon 6870 PCS+ review
This is the R6870 PCS+ version where PowerColor pre-overclocks the card to 940 MHz (900 reference) and clock the memory at 4400 MHz coming from 4200 MHz. This should give the card a nifty nice boost.
PowerColor Radeon 6850 PCS+ review
PowerColor is as always never late to arrive at the party, they submitted a Radeon HD 6850 for a test here at Guru3D.com and as such we'd be more than happy to bring you a full review on one of their newest products today, the PCS+ version of the Radeon HD 6850 that comes pre-overclocked.
