GeForce GTS 250 512MB vs Radeon RX 460

Intro

The GeForce GTS 250 512MB uses a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 memory is set to run at a frequency of 1100 MHz on this model. It features 128 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Compare those specs to the Radeon RX 460, which comes with core clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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