GeForce RTX 4070 Ti vs Radeon RX 6650 XT

Intro

Compare all of that to the Radeon RX 6650 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 2055 MHz. The GDDR6 RAM runs at a speed of 2190 MHz on this particular card. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6650 XT		176 Watts
GeForce RTX 4070 Ti		285 Watts
	Difference: 109 Watts (62%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 4070 Ti is 80% faster than the Radeon RX 6650 XT in general, due to its greater bandwidth. (explain)

GeForce RTX 4070 Ti		516096 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 229024 (80%)

Texel Rate

The GeForce RTX 4070 Ti should be a lot (about 111%) better at AF than the Radeon RX 6650 XT. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon RX 6650 XT		263040 Mtexels/sec
	Difference: 291360 (111%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 4070 Ti is the winner, by a large margin. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
Radeon RX 6650 XT		131520 Mpixels/sec
	Difference: 53280 (41%)

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 (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could 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 sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
