Let’s see the performance of the two new high-end video models from AMD that were released today, the Radeon HD 6950 and the Radeon HD 6970.
If you’re a gamer then you know the video card is probably the most important part of your system, without a decent one you won’t be able to play those games that you love so much. The problem with good video cards is that they cost a lot of money, and a lot of us can’t afford them so most of us aim a little lower towards the more mid-range priced cards. I think one should be able to get a fairly decent card that will play most games at relatively high settings and not have to take out a loan or get a second mortgage to do it. Today for review I’ve got the Sparkle GeForce GTX465 video card, it’s a fairly big card, but most cards are these days that can provide good performance for your system. The best part about this card I think is the price, for about $200 you can get a fairly decent performing card.
On our test bench is a GTX 570 from Gigabyte and the Radeon 6970/6950 from Sapphire. We will be overclocking each of these and putting them head to head against each other and an overclocked Radeon 5870 to find out how the new cards compare in this scenario. As always real world gameplay will be used, including Black Ops and HAWX 2 and just for fun we will throw in 3DMark 2011 Professional.
Nach unserem Test der Radeon HD 6850 und 6870 freuen wir uns euch mit der Sapphire Radeon HD 6850 TOXIC eine Karte präsentieren zu können, welche mit einer komplett überarbeiteten Kühlung, einem werksseitig erhöhten Takt und viel Overclockingpotenzial auf einem eigens designten PCB aufwarten kann und sich somit als Alternative zu den übrigen Modellen anbietet. Sapphires "Toxic"-Serie steht dabei schon seit dem R420 (Sapphire Radeon X800) für Taktraten am Limit, verbunden mit einer effizienteren Kühlung. Bisher konnte Sapphire diesem Anspruch gerecht werden, doch mit diesem Test wollen wir ermitteln, ob dies auch bei der Radeon HD 6850 Toxic gelungen ist.
Our second HD 6970 arrived and it was from no one other than AMD themselves. We knew that there was only one thing to do, though, and that was to Crossfire this bad boy. In October we saw the HD 6800s launch and when we tested them in Crossfire we were amazed at the awesome scaling the series was offering.
Some readers may remember that my first review of a GTX460 card was pretty negative – quite simply, the 768MB version I had been sent to test was no better than my GTX275 other than the DX11 capabilities, and in fact scored lower in most benchmarks than my older gen card. However, today I am reviewing the 1GB version – and not only that, the Inno3D “OC” version which is pre-overclocked to 820MHz core, 950MHz memory and a shader clock of 1640MHz – quite a step up from standard clocks (675MHz, 900Mhz, 1350Mhz respectively)
Graphic cards
In an attempt to tame the cards temperature from the 480's design, Nvidia have lost the heatpipe design that was in hindsight not fully up to the job and replaced this with a new vapour chamber designed heatsink. This along with a redesigned fan that is now around 5dB quieter, and that has also a quieter pitch than the squeaky fan of the 480. The new fan also pushes far more air in and through the heatsink in comparison to the old.
Last month nVidia rocked the graphics world with the release of their phenomenal GTX580. This is the fastest single chip card on the market today – although AMD’s HD5970 is still the most powerful graphics card on the planet. Today we are looking at the more affordable GTX570, which targets the same (£280) market as the HD6970.
Today on our test bench we have the result of ASUS' work on enhancing the 6870 design. The Radeon EAH6870 DirectCU is a factory overclocked model which claims to run cooler than the reference model and certainly looks different. We will be running it through a selection of real world tests to find out how it performs in gaming, multimedia and GPU computing tasks. These include Blu-Ray 3D, Stereoscopic 3D gaming and he latest releases such as Black Ops and H.A.W.X. 2.
With the introduction of AMD's Cayman GPU, the Radeon HD 6870 video card becomes their flagship DirectX-11 desktop video card. Gamers can expect the PowerColor Radeon HD 6970 to quench their thirst for demanding graphics power while introducing several new MSAA modes such as Enhanced Quality Anti-Aliasing (EQAA). The PowerColor Radeon HD 6970 features enhanced DirectX 11 tessellation effects, while still producing top-end frame rates to help gamers build their killstreak. In addition to a new VLIW4 shader core architecture, the Cayman GPU also offers accelerated multimedia playback and transcoding, AMD HD3D stereoscopic technology, and the 3D Blu-ray multi-view CODEC (MVC). In this article, Benchmark Reviews tests graphical frame rate performance of the PowerColor AX6970 2GBD5-M2DH using the most demanding PC video game titles and benchmark software available.
