GeForce GT 240 GDDR5 1GB vs Radeon RX 470 4GB

Intro

The GeForce GT 240 GDDR5 1GB makes use of a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 memory is set to run at a speed of 850 MHz on this particular model. It features 96 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.

Compare those specifications to the Radeon RX 470 4GB, which comes with a clock frequency of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also features a 256-bit memory bus, and uses a 14 nm design. It features 2048 SPUs, 128 TAUs, and 32 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
