GeForce GTX 550 Ti vs GeForce GTX 650
Intro
The GeForce GTX 550 Ti has a GPU core clock speed of 900 MHz, and the 1024 MB of GDDR5 memory runs at 1026 MHz through a 192-bit bus. It also is comprised of 192 Stream Processors, 32 Texture Address Units, and 24 Raster Operation Units.Compare all of that to the GeForce GTX 650, which uses a 28 nm design. nVidia has set the core speed at 1058 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this card. It features 384 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
Comments
4 Responses to “GeForce GTX 550 Ti vs GeForce GTX 650”I'm not sure about the increase of the performance from the GTX 550 Ti to GTX 650
even for me increase of performances between the 650 and 550ti are only in the Unified Shaders and the texel rate.
If you look at the following link http://www.geforce.com/Active/en_US/shared/images/products/shared/lineup.png just a little bit different. and even then only in synthetic benchmarks. not the real game.
Hi, what about video edition, which one is better to work for example in Adobe Premiere Pro CS6? or After Effects?
