GeForce GTS 250 1GB vs GeForce GTX 1050

Intro

The GeForce GTS 250 1GB makes use of a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 memory runs at a frequency of 1100 MHz on this specific model. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the GeForce GTX 1050, which features GPU clock speed of 1354 MHz, and 2048 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 32 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
