GeForce GT 1030 vs Radeon HD 4750

Intro

The GeForce GT 1030 features clock speeds of 1265 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the Radeon HD 4750, which features a clock frequency of 730 MHz and a GDDR5 memory frequency of 800 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is made up of 640(128x5) SPUs, 32 TAUs, and 16 ROPs.

The GeForce GT 1030 will be quite a bit (about 73%) better at 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

The GeForce GT 1030 should be quite a bit (about 73%) better at FSAA than the Radeon HD 4750, and should be capable of handling higher screen resolutions better. (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 largest amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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 calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
