AMD Radeon HD 6990 4GB
|
 AMD's second generation DX11 lineup is finally starting to take full shape and the latest card is one which many have been eagerly anticipating. Code named Antilles and officially called the HD 6990, it incorporates a pair of Cayman XT cores into a single PCB design which sports 4GB of GDDR5 and a sky high price of $699. This is obviously an enthusiast-oriented product but can it deliver in some of the most demanding situations?

AMD and NVIDIA based video cards
|
|
"The potential is there, but we just haven’t seen enough of it
yet. The idea is compelling, but the current implementations are
still behind the curve when being compared to native Crossfire or SLI
products. It is a good start, but I would argue that the technology
is still a bit immature. This hopefully will change. I cannot
reiterate enough that the potential for this technology is
outstanding, but delivering upon that promise is going to be a
challenge."

AMD Radeon HD 6990 Graphics Card Review
|
|
“The fastest graphics card in the world.” That’s what AMD says about their dual-GPU beast of a card, the HD 6990 that releases today. Will it ring true? With two of their top-of-the-line Cayman GPUs on board, it’s hard to think it wouldn’t. They’re not individually the fastest GPUs in the world, but can they reign supreme as a team?

Sapphire FleX Edition Radeon HD 6870 1GB
|
|
So, just what is the FleX Edition all about? It is the first line of Eyefinity capable Radeon cards that does not require an 'active adapter' or DisplayPort capable monitor in order to run in Eyefinity mode. That’s right, all you need are three DVI monitors (or two DVI, one HDMI) and a FleX Edition graphic card! Though the 6870 cards do still retain the ability to do 5x1-P (five screen, portrait), provided you have the dough for such a configuration! We will be focusing on the more budget-friendly 3-screen method on our HD 6870, so with that said; on with the show!

Sapphire Radeon HD 6990 4GB Technical Run Down
|
|
"We've got all our slide decks from AMD and some images from Sapphire. We'll tell you all the stuff we normally would in a video card review outside of the performance of course. Because there's so much to cover as well, it means we can get the performance article to you even faster while making sure we can cover as much information about the new dual GPU beast from AMD.
Looking at the package, there's nothing really all that different to what we've seen before. Of course, the brand and model are very noticeable; so is the fact that Sapphire has chosen to let us know that it's a "Dual GPU Graphics Card". Also on the front we can see a lot of the features like 4GB of GDDR5, DirectX 11, AMD HD3D, Display Port, High Speed HDMI, 7.1 HD Surround Sound and more. We can also see the new "Vision" labeling that AMD is going to start to push. The HD 6990 4GB falls within the "Black Vision" series which seems to be at the top of the tree."

AMD Radeon HD 6990 Dual-GPU Graphics Card Review
|
|
It's been a long while since we've last seen a $700 graphics card, but AMD revives that tradition with its Radeon HD 6990 dual-GPU offering. Fortunately, the card has proven that its high price-tag is well-earned, as it storms past every other single and dual-GPU graphics card on the market, and introduces other useful features to boot.

Zotac Geforce GTX 570 Review
|
|
"Zotac's Geforce GTX 570 does prove that is a direct competitor with any reference based HD 6970 at this given time. Through benchmarking and testing, both videocards won and lost during certain benchmarks and in the end, I can't and will not say one is better than the other. Regardless, Zotac's reference based version of the GTX 570 proved to be a great videocard and proved to work flawlessly right out of the box. The only hindrance would have to be the reference cooler which doesn't seem to be up to the task if you would like to overclock AND keeps things quiet and cool."

AMD Radeon HD 6990 Review: Sumptuous Dual-GPU Power
|
|
AMD introduced its first Radeon HD 6000 graphics card last October, when we reviewed the mid-range Radeon HD 6870. Since then AMD opened up to show its GPU roadmap and the cards that soon thereafter were coming to market.
The high-end Radeon HD 6970 and HD 6950 also arrived late last year, while the dual-GPU version of AMD's last generation graphics series code-named Antilles was expected to arrive shortly after. Coincidentally (or not) both AMD and Nvidia took a few months longer than expected to show its hardcore dual-GPU graphics cards, with the former making the first move to finally unveil the Radeon HD 6990.

AMD's own Radeon HD 5970
|
|
"I am glad to see AMD really embracing the overclocking mindset
in both its CPU and GPU divisions as well. AMD has been offering
unlocked processors for quite some time and with previous Radeon
releases and now the new HD 6990 offering, the engineering and
marketing teams continue to strive to beat out the competition in
anyway they can. By installing a switch on the card that now
basically overclocks the clock speeds and moves the power consumption
beyond approved levels, AMD is enabling consumers that WANT to push
their hardware the option to do so, and for that, we at PC Perspective
are very grateful."

ASUS GTX 570 DirectCU II Review
|
|
With its GTX 570 Direcet CU II, ASUS shows a factory
overclocked version of the NVIDIAs GTX 570 GPU. Additionally this card
got an overworked power design as well as ASUS huge triple slot
cooler. This should therefore be both more powerful and more silent.
