Our editors hand-pick related products using a variety of criteria: direct competitors targeting the same market segment, or devices that are similar in size, performance, or feature sets.
If AMD can improve frame time performance as they claim to be in the process of doing, then the 7990 could certainly become a real problem for the GTX 690 and GTX Titan. In the meantime, the Titan presents the safest bet for extreme performance at this privileged price point.
As impressive a feat of engineering as this beast is, there are faster, smoother and cheaper graphics arrays available, and much better enthusiast experiences to be had elsewhere.
As effective as the cooling is, The AMD Radeon HD 7990 is never going to have the premium aesthetic of the GTX Titan. In graphics card terms, it looks like a super car - it's practically got alloys. And if we take straight-line performance out of the...
Neither is quite fast enough nor sufficiently technologically advanced to oust its two main rivals, leaving the 7990 as a good card in search of a compelling reason for being. A price cut may well provide it with that reason, but until then it'll likely remain a second choice to most users.
For some years now, AMD has stopped short of bringing out a true high-range graphics chip, choosing instead to take its best chip and place two of them on the same card. Given that the 7990 follows in this line – essentially bolting two 7970 Tahiti chips...
AMD’s latest and greatest Radeon isn’t built on particularly new processing technology, but it’s nonetheless very powerful, and surprisingly quiet even running flat-out. If you’re looking for the current top dog, this is it, but we’re not sure how...
Before releasing its new-gen graphics cards, AMD seemed intent on claiming the title of fastest model on the market. That has definitely been achieved with the Radeon HD 7990. This twin-GPU graphics card beats its competitors on performance, but it's not...
The Nvidia GeForce GTX Titan is still the fastest single-GPU card on the market, but if you're looking for a dual-GPU solution, the AMD Radeon HD 7990 is a worthy competitor. Its overall performance is comparable to the Nvidia GTX 690 (or a pair of...
With that in mind, we can definitely recommend the Radeon HD 7990 to the ones that can afford a card of this caliber, it really is a top pick, but sure with some mixed feeling. It's not cheap but it is incredibly fun and silent. And with a product that is just loaded with performance it will certainly bring a smile to the faces of many.
A well-designed powerhouse of a card that gives as good as it gets from the very comparable NVIDIA GeForce GTX 690, the choice of which one to go for simply boils down to which brand you have more faith in: AMD or NVIDIA. If it was our money on the table we'd go with the slightly cheaper but performance-comparable GTX 690.
It does make me wonder why AMD had to release the HD 7990 now instead of waiting just a little bit longer, which would have given them the time to solve the frametime and CrossFire scaling issue and, last but not least, get rid of the coil whine.
The Fastest Card In The World? Perhaps. But unless you're limited by space or connector constraints a pair of HD 7970s or the cheaper GTX 690 4GB make more sense if you're going for that Extreme Ultra performance.
