GeForce GT 340 1GB vs Radeon RX 550

Intro

The GeForce GT 340 1GB uses a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 RAM runs at a speed of 850 MHz on this specific card. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Compare those specifications to the Radeon RX 550, which comes with core clock speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result 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 AA, High Dynamic Range and higher screen resolutions.

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

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