AMD Radeon HD 7990

Those looking for a powerful graphics card for their gaming PC should consider the AMD Radeon HD 7990. This graphics card offers many benefits, including PowerTune technology for better performance. It also features ZeroCore power technology, which allows it to run much more efficiently, resulting in less heat for your computer. In addition, the AMD HD 7990 also offers a range of display outputs, including HDMI, DisplayPort and DVI.

After the launch of AMD’s Radeon HD 7990 graphics card, the company officially announced a dual GPU graphics card. AMD’s new card was designed to rival the dual GPU GeForce GTX 690. It has a 375 W maximum power draw. The fan on the card kicks up during heavy gaming sessions. It also consumes 15 watts of power idle.

The new card combines two graphics processors on a single PCB. The card draws power from two 8-pin PCI-E connectors. The card also features four mini-DisplayPort 1.2 ports. It also supports a DVI-to-mini-DisplayPort dongle.

The new card uses AMD’s ‘RDNA architecture. This architecture features proprietary tweaks and different GPU configurations. It was initially announced as a graphics microarchitecture for Xbox Series X consoles. It was also confirmed to be used in the upcoming PlayStation 5 console.

Earlier this year, AMD announced the Radeon HD 7990 Dual-Chip graphics card. It features two of the world’s most advanced GPUs. AMD claims the card is designed to challenge all discrete graphics cards. It is one of the fastest dual-GPU graphics cards in the world and should keep the most demanding gamers satisfied.

AMD Radeon HD 7990 features dual Tahiti XT cores with 256 texture mapping units. These GPUs also include 64 Raster operating units. They work at 950 MHz effective and 1500 MHz peak. They feature a 384-bit memory bus. They are connected to the system using a PCI-Express 3.0 x16 interface.

The GPUs are cooled with three axial fans and a sizeable heatpipe assembly. They are also based on AMD’s Graphics Core Next architecture.

PowerTune technology of amd radeon hd 7990

Earlier this year, AMD introduced the Radeon HD 7970 GHz Edition, a big step forward in power efficiency. AMD’s ZeroCore power technology, which allows the GPU to shut off automatically when it’s not in use, was also introduced.

But the most significant upgrade to the Radeon HD 7990 is the introduction of AMD PowerTune, which uses various technologies to increase the card’s performance. AMD PowerTune uses eight distinct clock & voltage DPM states. Each state is based on the card’s current limits, the system’s temperature, and GPU activity. Dithering between these states occurs every ten milliseconds.

The 7990’s base clock is 950 MHz, but AMD PowerTune allows the card to reach a boost clock of 1000 MHz. The effective clock frequency is calculated by dividing the percentage of time the card is in each of the DPM states.

ZeroCore power technology of amd radeon hd 7990

Using ZeroCore power technology, the AMD Radeon HD 7990 graphics card can save power and maintain its low idle power consumption. It also helps in reducing heat. It takes into account user system configuration and application use. Moreover, it can lower clock speed via AMD PowerTune.

AMD’s new cards also incorporate ZeroCore Power. This technology automatically monitors the power draw, and if it is too high, it reduces the clock speed. The system can also take into account system temperature. It can also turn off other components when they are not needed.

The AMD HD 7990 draws around 20 Watts in idle mode. During gaming, the card consumes about 300 watts. The card is also relatively quiet. A 3-fan Heatpipe assembly cools it. However, its noise level is less soft than that of the Titan.

Pricing

Earlier this month, AMD dropped the price of their top-of-the-line graphics card. The HD 7990 will now sell for $799, a $200 discount from the original price of $1,000. This is a boon for buyers, who now can get more performance for less money.

While the new HD 7990 isn’t as fast as NVIDIA’s flagship dual GPU, it delivers better performance than the GTX 780 and is much cheaper. It’s hard to argue with the HD 7990’s performance, as it’s a powerful card that can deliver an exceptional 3D experience.

AMD has also fixed frame pacing issues, a common complaint for the two-GPU HD 6990. The new Catalyst 13.8 beta drivers have solved this problem by reducing micro-stuttering in DX 11 games.
