GeForce GTX 1650 vs Radeon HD 7950

Intro

Compare all of that to the Radeon HD 7950, which makes use of a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this model. It features 1792 SPUs along with 112 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 1650		131072 MB/sec
	Difference: 108928 (83%)

Texel Rate

The Radeon HD 7950 will be a bit (approximately 8%) more effective at AF than the GeForce GTX 1650. (explain)

Radeon HD 7950		89600 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 6440 (8%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1650 is superior to the Radeon HD 7950, and very much so. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 7950		25600 Mpixels/sec
	Difference: 21920 (86%)

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 maximum amount of information (in units of MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
