GeForce GT 230 vs Radeon RX 550

Intro

Compare all that to the Radeon RX 550, which makes use of a 14 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this specific model. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Radeon RX 550		35200 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 26400 (300%)

Pixel Rate

The Radeon RX 550 will be much (about 300%) faster with regards to AA than the GeForce GT 230, and should be able to handle higher screen resolutions better. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 13200 (300%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core clock 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels that 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 the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
