GeForce GTX 275 vs Radeon RX 460


Intro

The GeForce GTX 275 features a GPU clock speed of 633 MHz, and the 896 MB of GDDR3 RAM runs at 1134 MHz through a 448-bit bus. It also is made up of 240 Stream Processors, 80 TAUs, and 28 Raster Operation Units.

Compare those specifications to the Radeon RX 460, which uses a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this particular card. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
