GeForce GTX 1050 3GB vs GeForce GTX 650

Intro

The GeForce GTX 1050 3GB makes use of a 14 nm design. nVidia has clocked the core frequency at 1392 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this model. It features 768 SPUs as well as 48 TAUs and 24 ROPs.

Compare those specifications to the GeForce GTX 650, which has core speeds of 1058 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If 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 texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
