Nvidia Releases Mainstream GeForce GTX 550 Ti

Earlier this week NVIDIA introduced the newest member of its Fermi based GPU family the GeForce GTX 550 Ti. A mainstream minded card with a $150 price tag and performance numbers to match.



The GeForce GTX 550 Ti is currently the bottom end of NVIDIA's 500 series lineup and is meant to be the successor to the GeForce GTS 450 which was released last fall, but will not directly replace it in the marketplace. (Nvidia claims the GTS 450 will be for sale until at least later this year.)

Both cards feature similar specs and build architecture. The GTX 550 Ti is an evolution of the previous-generation's GTS 450 - both cards utilize 40 nm chips with a 238mm die packed with 1.17 billion transistors. They both also feature a single graphics processing cluster that's made up of four 48-core streaming multiprocessors (SMs) giving them an identical 192 CUDA cores apiece, but that's roughly where the similarities end.

The GTS 450's GF106 die utilized only two of a possible three memory-controller partitions, resulting in a 256KB L2 cache, two sets of eight ROPs and a 128-bit memory interface. Thanks to improved yields and transistor-level changes, the GTX 550 Ti's revised GF116 die makes full use of all three memory-controller partitions - that means a larger 384KB L2 cache, a total of 24 ROPs and a 50 per cent wider 192-bit memory interface capable of delivering almost twice the memory bandwidth.

Core clock and memory clock speeds are bumped from 783/900 MHz in the GTS 450 to 900/1026 MHz in the GTX 550 Ti.Nvidia claims that all these changes, taken together, result in 28 percent performance increase over what that of the GTS 450, and thus 20 percent more performance per watt.

GeForce GTX 550 Ti Specifications

    hello,

    I have buy this nvidia gtx550ti, wich looks really great.
    nothing to say, all was ok, gaming, etc...but when I opened Photoshop, I went to preferences and I was surprised to see that "open gl" was gray and it is writting that my video card has not GPU option for photoshop,

    but here too I have seen that this card is compatible open gl4.1,

    I don' t understand why in Photoshop it is saying that my card is not compatible open gl !!

    have you any idea ?
