As such, we won’t be diving in to them again here.
#Amd radeon hd 7990 series
Since the pair of Tahiti GPUs at the heart of the Radeon HD 7990 are identical to ones use on AMD’s previously-released, high-end Radeon HD 7900 series products, we’ve covered many of the GPU's key features at length already. There’s a lot more to the card that just its specifications though, as we’ll show you a little later.īefore we dig into the specifics of the new Radeon HD 7990, we’d like to direct you attention to a few past articles that will help lay the foundation for what we’ll be showing you on the pages ahead. But that’s because the Radeon HD 7990 is outfitted with two of the same GPUs and the same 3GB of frame buffer memory for each. It sports double the number of transistors, stream processors, texture units, ROPs, and memory as AMD’s previous flagship Radeon HD 7970. The Radeon HD 7990’s specifications seem very impressive upon initial inspection. The AMD Radeon HD 7990: Three Fans, Two GPUs, and a Massive Heatsink Strap yourself in and prepare to check out AMD’s most ambitious graphics card release to date. Its specifications are listed below and we’ve got the rest of the scoop on the pages ahead. Whatever strategery was involved that resulted in a later-than-expected launch of AMD’s dual-GPU powered Radeon HD 7990, it’s here now and we’ve got one. AMD has also enticed consumers with its “Never Settle” bundles, which has included many of the hottest games released in recent memory. Case in point, the Radeon HD 7970 GHz Edition and the Radeon HD 7950 with Boost, among others.
#Amd radeon hd 7990 drivers
NVIDIA’s been firing on all cylinders with its GeForce GTX 600 series products, but AMD has steadily wrung out additional performance from its products through updated drivers and refreshed products clocked slightly higher than their predecessors. Despite the relative age of its GPUs, the 7990 still has the potential to be the fastest graphics card to hit the market. Though the product has obviously been in development for quite some time, the Radeon HD 7990 is still an exciting proposition. That little tidbit alone should give you a good idea as to how long the Radeon HD 7990 has been simmering in AMD’s kitchen. We dropped those hints back then because AMD dropped them on us in the lead-up to the Radeon HD 7970’s release. In fact, it was all the way back in December of 2011, when AMD introduced the original Radeon HD 7970, that we first dropped hints that the dual-GPU powered Radeon HD 7990 was in the works. And we’re not talking about a few days or weeks here either. So, it attaches to each GPU through a 16-lane link, and then to the host interface with an additional 16 lanes.Today marks one of those funky occasions when you’ve probably been aware of the “new” product we’re going to show you for quite some time. The 48-lane, five-port device is manufactured at 40 nm and is PCI Express 3.0-capable.
Nestled between the two 4.3 billion-transistor chips is that PEX 8747 switch-the same one Nvidia uses to enable inter-GPU communication on the GeForce GTX 690. The frames per second performance puts it right where it needs to be to reign the super. The 3 GB of GDDR5 memory attached to each GPU runs at 1.5 GHz, just like AMD’s Radeon HD 7970 GHz Edition (in comparison, the original 7970 launched with a 1,375 MHz memory clock), delivering up to 288 GB/s per GPU. Overall the AMD Radeon HD 7990 is an impressive graphics card, its very well designed and engineered. That’s a little faster than the vanilla Radeon HD 7970, and a bit slower than the later GHz Edition version, which starts at 1 GHz and accelerates to 1.05 GHz. The company even sets the GPUs to operate at 950 MHz, with a 1 GHz boost state.
The graphics processors are complete-AMD doesn’t disable any of their resources, so each brings 2,048 Stream processors to the table, along with 128 texture units, 32 ROPs, and an aggregate 384-bit memory bus. We looked at all of them in Asus' ROG Ares II: Four Dual-GPU Graphics Cards, Compared, eventually coming to the conclusion that Nvidia’s GeForce GTX 690, while a bit slower in our benchmarks, made more sense than any of the Radeons. Finally, Asus threw its hat into the ring with a liquid-cooled card of its own, as obscenely-priced and limited as it was. HIS followed suit, giving us exclusive access to a couple of prototypes before withdrawing its plans to ship a dual-GPU solution altogether. PowerColor got out ahead of the rest with a dual-Tahiti offering that consumed three expansion slots, required three eight-pin auxiliary power connectors, and screamed like a banshee any time we applied a load to it. Rather, board partners tentatively dipped their toes into that high-end space. Of course, in the 12 months that followed, no official Radeon HD 7990 surfaced. And a dual-GPU card, based on two of the 7970’s Tahiti GPUs was rumored to be right around the corner.
