We were able to chase the GeForce GTX 560 OC edition Ti Coolstream by our well-known benchmark suite, a few days later they sent us the smaller brother, the Club3D GeForce GTX 550 Ti Coolstream OC edition. This model also has the Club 3D's own Cool Stream cooling system, and comes up under the hood with slightly higher clock speeds in addition, the dashing middle-class graphics card with 2048 MB is twice the amount available.
In the last days of April, we submitted our test article for Club3D GeForce GTX 560 Ti Coolstream OC edition online, but could not really convince the then graphics card, especially under load the two axial fan of the Cool Stream Cooler turned on so loud that they were partly to hear clearly from our closed test system. In addition, the cooling performance was hardly better than that of the reference - rather the opposite was the case to be fair, but noted, however, that it has made NVIDIA's board partners not easy and neatly presented, with its reference cooler.
Now, we sent a few days later, a Club3D GeForce GTX 550 Ti sample for Coolstream OC edition, this model also comes up with slightly higher clock speeds and is also the Cool Stream Cooler, which has, however, only on a single axial fan fitted. Thanks again to the reduced power consumption compared to the GeForce GTX 560 Ti could Club3D GeForce GTX 550 OC edition Coolstream Ti in terms of volume and cooling efficiency, eliminate the errors of its bigger brother.
The Club3D GeForce GTX 550 Ti Coolstream OC edition is based on NVIDIA GF116 chip he is, like all other current chipsets from the house also, in the 40-nm manufacturing process from the belt and boasts a total of 1.17 billion transistors - exactly as much as his immediate predecessor. But not only the complexity, it is strongly reminiscent of the GF106, even with much of the architecture is reminiscent of the previous version, sun owns the GF116 also has four multi-streaming processors, which consist each of 48 scalar units thus providing a total of 192 calculators.
As usual, each SM a texture cluster consisting of eight texture mapping units, ready, so it brings the NVIDIA GeForce GTX 550 Ti in a total of 32. The biggest differences between the two graphics chips, however, can be found in the memory configuration, had a NVIDIA GeForce GTS 450 to settle for a 128-bit wide memory interface, are the successors three 64-bit controller.
