GeForce GTX 275 vs Radeon RX 460 2GB

Intro

The GeForce GTX 275 has a clock speed of 633 MHz and a GDDR3 memory frequency of 1134 MHz. It also uses a 448-bit memory bus, and uses a 55 nm design. It is made up of 240 SPUs, 80 TAUs, and 28 ROPs.

Compare those specs to the Radeon RX 460 2GB, which comes with clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, 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 the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
