GeForce GTX 650 Ti vs GeForce GTX 970M

Intro

The GeForce GTX 650 Ti uses a 28 nm design. nVidia has set the core speed at 928 MHz. The GDDR5 memory is set to run at a speed of 1350 MHz on this model. It features 768 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Compare those specs to the GeForce GTX 970M, which uses a 28 nm design. nVidia has clocked the core frequency at 924 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular card. It features 1280 SPUs along with 80 Texture Address Units and 48 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better 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 chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
