GeForce GTX 1050 3GB vs Radeon HD 4750

Intro

Compare those specifications to the Radeon HD 4750, which uses a 40 nm design. AMD has set the core frequency at 730 MHz. The GDDR5 RAM is set to run at a frequency of 800 MHz on this model. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 ROPs.

Radeon HD 4750		51200 MB/sec
	Difference: 34816 (68%)

Texel Rate

The GeForce GTX 1050 3GB should be quite a bit (more or less 186%) faster with regards to AF than the Radeon HD 4750. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
Radeon HD 4750		23360 Mtexels/sec
	Difference: 43456 (186%)

Pixel Rate

The GeForce GTX 1050 3GB will be a lot (approximately 186%) more effective at FSAA than the Radeon HD 4750, and will be capable of handling higher resolutions better. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Radeon HD 4750		11680 Mpixels/sec
	Difference: 21728 (186%)

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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
