GeForce GTS 450 vs GeForce GTX 1050 3GB

Intro

The GeForce GTS 450 uses a 40 nm design. nVidia has clocked the core speed at 783 MHz. The GDDR5 RAM is set to run at a speed of 902 MHz on this specific card. It features 192 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Compare all that to the GeForce GTX 1050 3GB, which uses a 14 nm design. nVidia has clocked the core frequency at 1392 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this particular model. It features 768 SPUs along with 48 TAUs and 24 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
