GeForce GT 1030 vs Radeon HD 4750

Intro

The GeForce GT 1030 makes use of a 16 nm design. nVidia has set the core speed at 1265 MHz. The GDDR5 RAM 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 4750, which has clock speeds of 730 MHz on the GPU, and 800 MHz on the 512 MB of GDDR5 memory. It features 640(128x5) SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

GeForce GT 1030 49152 MB/sec
Difference: 2048 (4%)

Texel Rate

The GeForce GT 1030 will be quite a bit (more or less 73%) faster with regards to texture filtering than the Radeon HD 4750. (explain)

GeForce GT 1030 40480 Mtexels/sec
Radeon HD 4750 23360 Mtexels/sec
Difference: 17120 (73%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 1030 is superior to the Radeon HD 4750, and very much so. (explain)

GeForce GT 1030 20240 Mpixels/sec
Radeon HD 4750 11680 Mpixels/sec
Difference: 8560 (73%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
