How well can the Radeon HD 7990 run games
AMD Radeon HD 7990
10 Aug 2021 - Graphics card reviewed

A mid to low level graphics card, the Radeon HD 7990 is found in budget machines nowadays, struggling to meet AAA system requirements.

Capable of running games with up to a DirectX 11 requirement.

Lets look at the Radeon HD 7990 game performance guide for some of the biggest games played in 2023. In particular we will see how well this graphics card runs on Ultra settings on 1080p resolution as well as 1440p and 4K. Of the 1000 most demanding recommended specs found in game requirements today, this gpu is more powerful than the graphics requirement of 445 games in todays list.

First we looked at 1080p resolution for the Radeon HD 7990 performance to explore what sort of benchmarks it would achieve on the popular title Back 4 Blood and saw it deliver playable frames per second across the following graphics settings - Low: 115 FPS, Medium: 90 FPS, High: 61 FPS and Ultra: 44 FPS. We proceeded to look at Star Citizen to see how that compared and predict that it will return a reasonable 51 FPS at Ultra 1080p.

We move on to 1440p, and tested Back 4 Blood which delivered playable FPS results. Here are the graphic presets - Low: 88 FPS, Medium: 69 FPS, High: 46 FPS and Ultra: 33 FPS. Next we have Star Citizen running on Radeon HD 7990 which is predicted to get L: 102FPS, M: 80FPS, H: 54FPS, U: 39FPS. And for performance contrast the popular Days Gone gets L: 102FPS, M: 80FPS, H: 54FPS, U: 39FPS at 1440p. Running games at 1440p with a Radeon HD 7990 is a reasonable choice at this screen size. You can always tweak modern game graphics settings to help you get a better High graphics setting experience at 1440p.

How many years will the Radeon HD 7990 graphics card play newly released games and how long until you should consider upgrading the Radeon HD 7990 in your PC? Our current calculations suggest a graphics card upgrade will be required in around 12-18 months

Whats a good PC graphics upgrade for the Radeon HD 7990? There are no graphics cards on the current market that would provide a big enough increase in performance to warrant upgrading the Radeon HD 7990.

Radeon HD 7990 Game Requirement Analysis

Radeon HD 7990 is a Dual-Graphics Solution based on the Graphics Core Next (GCN) Architecture.

The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.

It equips two GPUs Codenamed Tahiti XT which together have 64 Compute Units activated and thus offer 4096 Shader Processing Units, 256 TMUs and 64 ROPs. The Central Unit is clocked at 950MHz and goes up 1000MHz, in Turbo Mode.

Each GPU accesses a 3GB frame buffer of Fast GDDR5 Memory, through a 384-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1500MHz.

Power Consumption
With a rated board TDP of 375W, it requires at least a 750W PSU with two available 8-pin connectors.

Radeon HD 7990 Competes with GeForce GTX 690 and proves to be considerably faster at resolutions over 2560x1600.

System Suggestions
Radeon HD 7990 is best suited for resolutions up to and including 2560x1600. We recommend a Very Strong Processor (Intel Core i7 Quad Core/AMD FX Eight Core) and 16GB of RAM for Optimal Performance.
