GeForce RTX 3050 vs Radeon R7 250

Intro

Compare those specs to the Radeon R7 250, which has GPU core speed of 1000 MHz, and 1024 MB of GDDR5 RAM set to run at 1150 MHz through a 128-bit bus. It also is comprised of 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Radeon R7 250		24000 Mtexels/sec
	Difference: 100160 (417%)

Pixel Rate

The GeForce RTX 3050 should be a lot (more or less 521%) more effective at full screen anti-aliasing than the Radeon R7 250, and capable of handling higher resolutions without losing too much performance. (explain)

GeForce RTX 3050		49664 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 41664 (521%)

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 information (counted in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels 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 Raster Operations Pipelines by the the core clock speed. 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
