Two GF110 chips on a single PCB, 365 W on the clock, and a duel that still holds water: NVIDIA’s dual-GPU card has not said its last word.
GTX 590 vs HD 6990, match nul sous stéroïdes
ComputerBase brings out the file of the GeForce GTX 590, launched in March 2011 against the Radeon HD 6990. Common objective at the time: maximize the fps, while taking into account consumption and noise.
Under the fairing, the GTX 590 lines up two complete GF110s, the equivalent of two GTX 580s clocked lower. Each GPU has 1,536MB of GDDR5. The whole thing climbs to 365 W of TBP and requires two 8-pin connectors.
Performance: NVIDIA advantage in 1680×1050, AMD regains control in 2560×1600 4xAA/16xAF
ComputerBase measurements confirm overall balance. In 1680×1050, the GTX 590 signs an index of 100.0 against 94.8 for the HD 6990. In 2560×1600 with 4xAA and 16xAF, shifts in favor of AMD: 106.8 for the HD 6990 against 100.0 for the GTX 590.
This diagram reproduces the original conclusions: NVIDIA holds intermediate resolutions better, AMD expresses itself more in high definition and advanced filtering.
Micro-saccades and pilots, the other nerve of the duel
In 2011, the AFR imposed its share of micro-stutters on dual-GPU cards. Both models are sensitive to this, but ComputerBase credits NVIDIA with more advanced profiles and drivers at launch, making the GTX 590 less affected than the HD 6990 at equivalent rendering.
Beyond the average fps, this piloting advantage weighed on the experience. With similar components, the perception of fluidity remained a key differentiator.
