Architecturally, the GF110 chips used in the GeForce GTX 590 are not very different from the GF100 on which the first model of the Fermi line, the GTX 480, is based. Both GPUs use the same multiprocessor configuration, these chips consist of four Graphics Processing Clusters.
The new GeForce GTX 550 Ti model, based on the improved GF116 GPU, will not replace the GeForce GTS 450 graphics card in the market. At the beginning of its journey, these two models will coexist in the company's lineup together.
As in the case of the GeForce GTX 580/570, the organization of the new core has not changed. Essentially, the GF114 is a fully active GF104 optimized to achieve higher clock speeds while keeping power consumption within reasonable limits.
When designing the GTX 570, NVIDIA designers followed the same path, reducing the number of stream processors and the bus width. The novelty has 15 multiprocessors (respectively, 480 CUDA cores remain) and 5 memory controllers (bus width 320 bits, 40 ROP blocks).
The new GeForce GTX 580 is nothing revolutionary. The main task that the company's engineers faced was to correct the mistakes made earlier, as well as to increase performance for a more significant lead over the main competitor AMD.
