GeForce GTX 1650 vs Radeon HD 4750

Intro

Compare those specifications to the Radeon HD 4750, which makes use of a 40 nm design. AMD has set the core speed at 730 MHz. The GDDR5 RAM is set to run at a speed of 800 MHz on this card. It features 640(128x5) SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 1650 should be 156% faster than the Radeon HD 4750 overall, due to its greater bandwidth. (explain)

GeForce GTX 1650		131072 MB/sec
Radeon HD 4750		51200 MB/sec
	Difference: 79872 (156%)

Texel Rate

The GeForce GTX 1650 should be much (approximately 256%) better at anisotropic filtering than the Radeon HD 4750. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 4750		23360 Mtexels/sec
	Difference: 59800 (256%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1650 is superior to the Radeon HD 4750, by far. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 4750		11680 Mpixels/sec
	Difference: 35840 (307%)

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: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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 - the lower the bandwidth is, the lower the potential to reach the max fill rate.
