To the Geforce GTX 550 Ti apart from the wider memory interface to speed over the GTS 450, NVIDIA has increased the clock speeds on 900/1.800/2.052 instead 783/1.566/1.800 MHz. So are 15 percent more processing power and a 71 percent increase in memory bandwidth available. The remaining technical details are as follows: Support for DirectX 11, OpenGL 4.1, OpenCL 1.1, PhysX, CUDA, SLI, 3D Vision (plus surround SLI), optional HQ AF, SGSSAA in all APIs and True HD audio bitstreaming and a DP-power corresponding to one twelfth of the SP-performance. The reference design offers two dual-link DVI ports and a mini HDMI port and a dual-slot cooling Axiallüfterbasis on which we exchanged for this Palit card has a DVI to VGA port. A special feature is the single 6-pin power connector: Apart from the GTX 460 in the OEM version of the GTX 550 Ti is the fastest Nvidia card with this type of power supply. If this is the AMD Radeon HD 6850 and which is clearly faster and GeForce GTX 550 ti more economical, much can be said.
Those who do not turn in each game has maximum detail that gets even at low-cost graphics cards below 150 € more than enough performance for most games. So far, Nvidia was set up badly in this segment. Now, the new GeForce GTX 550 Ti the attack available from 110 € perennial Radeon HD 5770 directly. Nvidia's so far best DirectX 11 graphics card, the Geforce GTS 450 count, nearly one-third slower than the Radeon similarly expensive and is therefore not an option.
