Decide for yourself if this is a deal-breaker. Igor in our German office created some video and performed frequency analysis that you’ll be looking at shortly. I don’t think it’s particularly ideal to have to use v-sync, but there it is. The solution is to turn on v-sync, capping the frame rate and preventing those highly variable loads. The volume and tone of this phenomenon vary according to the task you’re performing, but it was noticeable enough during our real-world game testing with Bakersfield-based volunteers that several asked me to explain what was happening.

AMD explained it to me as an artifact of oscillation between heavy and light workloads, where current draw spikes and dips, causing ceramic capacitors and the PCB itself to vibrate. To a lesser degree, the Radeon HD 7990 runs into something similar. But I was surprised at just how much noise the card’s inductors generated-like, I couldn’t believe an engineer would kick something like that out the door and expect someone to pay a grand for it.

Previously, PowerColor sent in its AX7990 6GBD5-A2DHJ Devil13 for us to look at. 1080p performance for the Radeon HD 7990, stacked up against the GTX Titan, the GTX 780 and the single chip Radeon HD 7970 GHz Edition - the core tech that AMD has doubled up to create its current. The Radeon HD 7990’s cooling fans spin quietly-something I was so happy AMD addressed. Given that the first fan’s blades protrude up above the plastic shroud a tad, you won’t want to put two 7990s right next to each other in a quad-CrossFire configuration. There’s also a metal plate on the back of the PCB. Fortunately, both of its eight-pin power connectors are up on top of the board, so you don’t have to worry about leads extending another inch or two behind the already-long add-in. That’s an inch longer than GeForce GTX 690. If you demand the fastest graphics card at this moment in time, however, you should buy the Radeon HD 7990.Physically, the Radeon HD 7990 measures the same 12-inches long as Radeon HD 6990. Multi-GPU graphics cards can sometimes have issues with drivers, and you may therefore prefer a single GPU card such as the excellent GTX Titan. The Radeon HD 7990 is certainly expensive, but it’s also the fastest graphics card we’ve seen.

The sound isn’t so horrid that we’d rather turn off our PC and read a book instead, but it is irritating.

Although the Radeon HD 7990 is quiet, and was pretty much silent when we just used the Windows desktop, it sounds like a colony of crickets when the fan speed increases. To produce these low sound levels, the AMD reference design uses a large heatsink and three fans to cool the board. Reducing the graphics quality to Extreme allowed a much smoother average frame rate of 59fps.ĪMD claims the Radeon HD 7990 is quieter than the GTX Titan, a card that is impressively quiet given its great performance. This is much faster and smoother than the frame rate produced by the GTX Titan when running Crysis 2 in Nvidia’s Surround multi-monitor mode, as the Titan produced just 24.6fps. With Crysis 2, it produced 39.6fps at Ultra quality. Reducing Dirt Showdown’s graphics quality to Medium produced an average frame rate of 112fps and reducing it even further to Ultra Low produced 156.9fps. At Ultra quality and with 4x anti-aliasing, the HD 7990 produced a stunning frame rate of 90.2fps. It certainly coped well when playing Crysis 2 and Dirt Showdown at a resolution of 5,760x1,080 over three screens in Eyefinity mode.

Sadly, we’re unable to test the Radeon HD 7990 at these super-high resolutions, but we’re sure it’ll cope. Indeed, AMD claims the Radeon HD 7990 is well suited to very high resolution displays, such as the new 3,840x2,160-resolution “4K” displays. We weren’t disappointed, as the Radeon HD 7990 produced an average frame rate of 60.3fps in Crysis 2 and 104.9fps in Dirt Showdown, which means that a drop in performance, if there is a drop in performance, is negligible.

With higher resolution monitors now available, we were keen to see how the Radeon HD 7990 would perform at resolutions higher than Full HD, so we conducted the same tests at a resolution of 2,560x1,440. The GTX Titan produced an average frame rate of 49.6fps in the same test. GeForce GTX 690: The Pepsi Challenge : AMDs Malta Becomes The Radeon HD 7990 : Much-Improved Acoustics, With One Nagging Issue : Test Setup, An Explanation Of. The AMD Radeon HD 7990 also scored highly in our Crysis 2 test, producing an exceptional 60.2fps at a resolution of 1,920x1,080 and Ultra quality. This is faster than the Nvidia GTX Titan's frame rate of 91.1fps, which was scored under the same conditions. We tested the Radeon HD 7990 with Dirt Showdown at a resolution of 1,920x1,080 and 4x anti-aliasing at Ultra quality and it produced a stunning frame rate of 106.7fps. The HD 7990 is both huge and power-hungry, as you'd expect for a dual GPU card
