GeForce GTX 1630 vs Radeon HD 4750

Intro

Compare that to the Radeon HD 4750, which uses a 40 nm design. AMD has clocked the core frequency at 730 MHz. The GDDR5 memory is set to run at a speed of 800 MHz on this model. It features 640(128x5) SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1630 will be 92% faster than the Radeon HD 4750 in general, due to its greater bandwidth. (explain)

GeForce GTX 1630		98304 MB/sec
Radeon HD 4750		51200 MB/sec
	Difference: 47104 (92%)

Texel Rate

The GeForce GTX 1630 will be quite a bit (more or less 138%) better at texture filtering than the Radeon HD 4750. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon HD 4750		23360 Mtexels/sec
	Difference: 32320 (138%)

Pixel Rate

The GeForce GTX 1630 will be a lot (about 138%) faster with regards to full screen anti-aliasing than the Radeon HD 4750, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon HD 4750		11680 Mpixels/sec
	Difference: 16160 (138%)

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 data (measured in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, 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 most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
