GeForce RTX 3090 vs Radeon R7 240

Intro

Compare all of that to the Radeon R7 240, which has a GPU core clock speed of 730 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 128-bit bus. It also is made up of 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240		30 Watts
GeForce RTX 3090		350 Watts
	Difference: 320 Watts (1067%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3090 is 3229% faster than the Radeon R7 240 in general, because of its greater bandwidth. (explain)

GeForce RTX 3090		958668 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 929868 (3229%)

Texel Rate

The GeForce RTX 3090 is quite a bit (about 3034%) faster with regards to AF than the Radeon R7 240. (explain)

GeForce RTX 3090		457560 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 442960 (3034%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3090 is superior to the Radeon R7 240, and very much so. (explain)

GeForce RTX 3090		156240 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 150400 (2575%)

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 max amount of data (counted in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core 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 also depends on many 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.
