GeForce GTX 650 Ti 2GB vs GeForce GTX 750 Ti
Intro
The GeForce GTX 650 Ti 2GB makes use of a 28 nm design. nVidia has set the core speed at 928 MHz. The GDDR5 memory works at a frequency of 1350 MHz on this specific model. It features 768 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the GeForce GTX 750 Ti, which comes with core clock speeds of 1020 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.

2 Responses to “GeForce GTX 650 Ti 2GB vs GeForce GTX 750 Ti”With all due respect I think you got the texel rate wrong on the GTX 750 Ti , If that was the case nobody would be buying the 750 Ti over the GTX 650 Ti because it would be much slower.
Also you have the pixel rate wrong on the non Ti GTX 650,
por lo que dices la gtx 750 Ti es peor que la gtx650 Ti. No le veo sentido la verdad. Así lo único que consigues es confundir a la jente.
