GeForce GT 1030 vs Radeon HD 3870 512MB

Intro

The GeForce GT 1030 features a clock frequency of 1265 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 64-bit memory bus, and uses a 16 nm design. It is made up of 384 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the Radeon HD 3870 512MB, which makes use of a 55 nm design. AMD has clocked the core speed at 775 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this card. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
