It has certainly been an interesting couple of months for the high end gaming enthusiast. In October AMD brought out their R9 290 and R9 290X which took the performance crown from Nvidia. We felt both cards were fantastic, but the substandard reference cooler forced us to offer a hesitant recommendation, and we have advised people to wait on the custom cooled solutions. The Nvidia GTX780Ti was then released earlier this month, reclaiming the crown. While AMD partners still scramble to bring improved R9 290/290X models to market, Nvidia are already a leap ahead. Today we review a highly customised, overclocked three fan card from market leader, Palit.
Over the past several years of testing desktop graphics hardware, I've enjoyed a unique perspective of the internal happenings that remain hidden from the public. Much like politics, there is the truth, and then there's what you've been convinced into believing. I've watched their tactics, and witnessed their desperate attempts to sway consumer opinion. As competition for sales within the desktop graphics segment provokes fierce competition, it also raises the stakes for the companies involved. NVIDIA's Fermi GF110-powered GeForce GTX 580 sets the standard, but will AMD's VLIW4 architecture Cayman GPU save the Radeon HD 6970? In this editorial article, I'll share my opinion of what appears to be the last stand between the AMD Radeon and NVIDIA GeForce desktop graphics platform.
AMD's new Radeon HD 6990 video card reclaims the top spot in their overall GPU product hierarchy. There is no single-GPU card that can compete with two Cayman-class Radeon HD 6870 processors running in tandem. This was also true for the prior generation's king, the HD 5970, and at first glance the 6990 looks like a one-for-one replacement, but is it? Not really; it's better, or I should say it's more better. The PowerColor Radeon HD 6990 takes a slightly different tack, as the full complement of shaders (1536) is always available from each GPU. There is a BIOS switch that unlocks the core clock and the GPU voltage for the more adventurous among us. Normally that kind of enhancement-on-a-switch might seem a bit ho-hum, but with the power of 5.3 billion transistors on board, there are physical limits that must be respected. Heat and power go hand in hand, and some say it's folly to try and pack this much power into a single package. It's better to! have two cooling systems, and two slots, and two sets of PCI-E power connectors to spread the load, they claim. They may be right; we'll just have to test it and see... Follow along with Benchmark Reviews as we put the new PowerColor AX6990 4GBD5-M4D to the test.
AMDs neue „High End“-Karten sind da: Radeon HD 6970 und Radeon HD 6950 setzen auf die „Cayman“-GPU, die die bis dato schnellsten Single-GPU-Karten alt aussehen lassen soll. Wie groß der Schritt nach vorne ist, werden wir anhand zahlreicher Tests beider 3D-Beschleuniger herausfinden. Reicht die Leistung, um auch die GeForce GTX 580 zu gefährden?

Looking at the title, we've called this a review, but in reality, it's not really as we won't be looking at the hardware used in their own entity but instead will be purely focussing on the performance that three 6950 Radeon's can output when put into a multi GPU configuration.
If the emails we have been receiving for the last month have been anything to go by, the enthusiast gaming audience is warming to the thought of low cost multiple monitor configurations. We recently reviewed the mouth watering XFX HD5970 Black Edition Limited 4GB in CrossfireX, but as many people have pointed out, this is merely a toy for the rich.
We overclock NVIDIA's new GeForce GTX 780 video card to see just what kind of performance we can get out the new GPU. It has the $999 GTX TITAN in its view.
ATIs Geschichte beginnt im Jahr 1985, also noch vor dem Mauerfall und lange bevor an Pixel-Shader und DDR-Speicher zu denken ist. Gegründet wird das Unternehmen am 20. August 1985 als ATI, eine Abkürzung für "Array Technology Industry", von den Auswanderern Kwok Yuen Ho (Chief Executive Officer bis zum Jahr 2004), Benny Lau und Lee Lau mit einem Startkapital von für heutige Verhältnisse bescheidenen 300.000 US-Dollar. Während Ho aus Guangzhou stammt, haben die beiden Brüder Lau ihre Wurzeln in Hong Kong. Alle drei eint, dass sie nach Kanada gekommen waren, um Arbeit zu finden. Frustriert über die aussichtslose Situation gründen sie schließlich ATI in Markham, Kanada.
The GeForce GT 440, an entry-level DirectX 11 video card, can come with two memory configurations: 512 MB GDDR5 running at 3.2 GHz (51.2 GB/s) or 1 GB DDR3 running at 1.8 GHz (28.8 GB/s), both costing exactly the same. So, which is the better option, a GeForce GT 440 with less but faster memory, or a GeForce GT 440 with more but slower memory? Check it out.
The SAPPHIRE HD 7950 3GB OC Vapor-X Edition has a core clock speed of 950 MHz and 3GB of GDDR5 memory clocked at 5000MHz (effective). We put this custom card to the test to see how it performs in the games and how well it can overclock. With a healthy factory overclock and the Vapor-X cooler this card should perform well, but you never know unless you try it out!
