GeForce GTS 250 1GB vs Radeon RX 6500 XT

Intro

Compare that to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has set the core frequency at 2200 MHz. The GDDR6 RAM is set to run at a speed of 2250 MHz on this particular model. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTS 250 1GB		70400 MB/sec
	Difference: 77056 (109%)

Texel Rate

The Radeon RX 6500 XT should be quite a bit (more or less 198%) more effective at texture filtering than the GeForce GTS 250 1GB. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTS 250 1GB		47232 Mtexels/sec
	Difference: 93568 (198%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6500 XT is a better choice, by a large margin. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTS 250 1GB		11808 Mpixels/sec
	Difference: 58592 (496%)

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 largest amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
