GeForce RTX 4070 Ti vs Radeon R7 250X 2GB

Intro

Compare all that to the Radeon R7 250X 2GB, which has a core clock frequency of 1000 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

The GeForce RTX 4070 Ti should be quite a bit (more or less 1286%) better at anisotropic filtering than the Radeon R7 250X 2GB. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 514400 (1286%)

Pixel Rate

The GeForce RTX 4070 Ti should be quite a bit (about 1055%) faster with regards to AA than the Radeon R7 250X 2GB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 168800 (1055%)

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 data (counted in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 can be processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
