Radeon R7 250X vs Radeon RX 6700 XT

Intro

Compare all of that to the Radeon RX 6700 XT, which comes with core clock speeds of 2321 MHz on the GPU, and 2000 MHz on the (Unknown) MB of GDDR6 RAM. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
Radeon RX 6700 XT		230 Watts
	Difference: 135 Watts (142%)

Memory Bandwidth

In theory, the Radeon RX 6700 XT should be much faster than the Radeon R7 250X in general. (explain)

Radeon RX 6700 XT		393216 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 321216 (446%)

Texel Rate

The Radeon RX 6700 XT should be a lot (more or less 828%) more effective at AF than the Radeon R7 250X. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 331360 (828%)

Pixel Rate

The Radeon RX 6700 XT should be much (approximately 828%) faster with regards to full screen anti-aliasing than the Radeon R7 250X, and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 132544 (828%)

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 (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 potential to get to the max fill rate.
