GeForce GT 1030 vs Radeon HD 4830 512MB

Intro

The GeForce GT 1030 makes use of a 16 nm design. nVidia has clocked the core frequency at 1265 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this card. It features 384 SPUs along with 32 TAUs and 16 ROPs.

Compare those specs to the Radeon HD 4830 512MB, which has GPU clock speed of 575 MHz, and 512 MB of GDDR3 memory set to run at 900 MHz through a 256-bit bus. It also is made up of 640(128x5) Stream Processors, 32 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
