In addition to being a low profile silent media PC ready card, the Sapphire Radeon HD6450 Flex Edition video card also boasts triple DVI monitor support right out of the box. This is impressive for a sub $100 card, But what kind of performance can a $70 card really provide? See why this super cheap card packs features and performance that may just surprise you.
So far we've had some good success when it comes to overclocking which we looked at in our HIS HD 7970 and XFX HD 7970 Black Edition Double Dissipation review. Adding a second card into the mix is known for limiting overclocking ability as cards are placed together and more heat is generated. Those numbers are then amplified due to the added voltage being thrown through the core of each GPU.
Since we've already looked at the Sapphire HD 7970 in our original CrossFire review, we won't need to have a look at the card again. Instead we'll get straight into the testbed setup and quickly cover how we went with the overclock. Once we've done that we'll just get straight into the performance.
The big issue we knew we would run into at the launch of the HD 7950 was getting two cards that would carry the same cooler because AMD had given its partners the chance to do whatever they wanted when it came to the fan this time around.
Thanks to Sapphire, though, we had the opportunity to get a pair of HD 7950s that we knew would carry the same cooler making it the perfect setup for CrossFire testing. Since we haven't looked at these cards yet the first thing we need to do is check out the package.
Last month AMD introduced the Radeon HD 7000 series (Southern Islands) of graphics cards. These new cards are based on the 28nm manufacturing process and use a new core architecture called Graphics Core Next (GCN). Many assumed that AMD would be doing a top-to-bottom launch for the AMD Radeon HD 7000 product line, but that is not the case. AMD decided skip over Pitcairn, the Radeon HD 7800 series, and introduce Cape Verde along with the Radeon HD 7700 series.
On February 15th AMD released their new HD7750 and HD7770 graphics cards targeting the mainstream enthusiast audience. On launch day we reviewed HD7770 and HD7750 cards from partners such as VTX3D, HIS and Sapphire. Our XFX sample was originally misplaced in the mail so we held fire until today to review two of their new HD7770 Black Edition cards in Crossfire along with their latest HD7750 Double Dissipation Edition.
Serious gaming starts here" - mit diesen markigen Worten bewirbt AMD seine neuesten Grafikkarten. Wie kräftig die dritte 28-Nanometer-GPU im Vergleich zu verbreiteten Grafikkarten wirklich ist und ob sich das Aufrüsten lohnt, klärt der PCGH-Test.
Very few manufacturers can compete with Sapphire when it comes to creating a flagship video card. Over the last year they have consistently released some of the finest graphics cards to market. Today we are looking at their latest high end HD7970 Overclock Edition which is supplied with twin bios overclock configurations and proprietary twin fan cooling solution.
Today we take a detailed look at gaming performance of the GTX 680 in titles such as Mass Effect 3 and Battlefield 3 with single screen and surround gaming as well as Stereoscopic 3D testing. Added to that is GPU computing and media playback performance along with thermal, power, noise and overclocking results. Want to see how the GTX 680 does against the 7970 at its maximum overclock, or the GTX 580 OC 3GB we have that sorted too...
Based on a custom design the XFX Radeon R7850 Black Edition Double Dissipation is factory overclocked and has a familiar look to the more expensive 7900 series XFX cards. Today we will take a look at it in a selection of the latest games to find out what it offers over a standard design. Additionally we will be taking a look at the various anti-aliasing modes available on the XFX card and how they affect performance and image quality.
China is enjoying increasing success with its own CPU developments, even though for now it is confined to the internal markets mostly. However, they are already undertaking the next step, and preparing to move into the GPU arena.
