You can learn more about AMD Eyefinity technology on the official website. You connect monitors to the different graphics cards in a SLI tandem whereas with a CrossFireX tandem you connect all three monitors to one card and then just add a second card and join the cards with a bridge connector. The only exception concerns CrossFireX mode. They are in fact the same but structured differently. We can’t say that the setup options are easier to use or simpler than in the GeForce driver.

The Catalyst driver offers all the related settings if you ever need them, though. The native resolution of the monitors (1920×1080) was identified automatically and we were asked whether to combine them in multi-display mode and what orientation to use (portrait or landscape). Interestingly, our multi-monitor setup didn’t even call for any configuring. We connected them to the HD 7970’s DVI-I connector and mini-DisplayPorts using adapters included with Sapphire cards (thanks Sapphire for that!). We wouldn’t have had enough room for as many as six monitors, so we limited ourselves to three. Using its two mini-DisplayPorts and a special MST hub, which is already available in shops, you can enable multi-stream technology to support up to six monitors on a single card. The card isn’t limited to four monitors, though. But it also has one HDMI 1.4a and two DisplayPort 1.2 interfaces. AMD EyefinityĪs opposed to Nvidia’s GeForce GTX 690 and 680, AMD’s single-processor flagship Radeon HD 7970 GHz Edition has only one dual-link DVI-I connector. We could have also used the card’s DisplayPort, though.

Before proceeding to tests, let’s see how to configure multiple monitors for Nvidia and AMD graphics cards. As opposed to its archrival AMD, Nvidia is new to this kind of gaming (which is yet not very popular among end-users, we must admit) because its single graphics cards have only come to support multi-monitor configurations with the release of the Kepler architecture and GeForce GTX 6xx series. In this review we want to check out one and two GeForce GTX 690s in Surround mode using three monitors and a very high display resolution. However, there are exceptions as we will see shortly. Indeed, a single GeForce GTX 690 is more than capable of keeping the average frame rate above 100 fps in the majority of today’s games. Many users are prone to view the GTX 690 as overkill, especially when it comes to joining two such cards in a SLI tandem.
Additionally, The EX58-UD3R-SLI features Intel ® Turbo Boost Technology, which is able to power down idle processor cores and dynamically reroute the power to the active cores for significant performance boosts, and at the same time, maintain greater energy efficiency.The dual-processor Nvidia GeForce GTX 690 is the fastest gaming graphics card today and will remain such at least until the highly anticipated AMD Radeon HD 7990 comes out. The Intel ® Core i7 processors also feature an integrated memory controller inside the processor die and support 192bit 3-channel DDR3 memory that delivers a 50% memory bandwidth enhancement and lower memory latency for incredibly fast memory access. Replacing the Front Side Bus is the new Quick Path Interconnect, or QPI, whose 25.6 GB/sec transfer rate (double the bandwidth of the 1600MHz FSB) eliminates the communication bottleneck between the processor and chipset. The EX58-UD3R-SLI was designed specifically to take advantage of the raw power of the next generation Intel ® Core i7 processors and the Intel ® X58 Express chipset, whose new evolution in computing architecture is able to deliver an amazing performance break through from past processor generations.
