GeForce GTX 465 vs Radeon RX 6500 XT

Intro

Compare those specifications to the Radeon RX 6500 XT, which features a core clock speed of 2200 MHz and a GDDR6 memory speed of 2250 MHz. It also makes use of a 64-bit memory bus, and makes use of a 6 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 465		200 Watts
	Difference: 93 Watts (87%)

Memory Bandwidth

In theory, the Radeon RX 6500 XT is 44% quicker than the GeForce GTX 465 overall, because of its higher bandwidth. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 44864 (44%)

Texel Rate

The Radeon RX 6500 XT should be quite a bit (approximately 427%) better at texture filtering than the GeForce GTX 465. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 114092 (427%)

Pixel Rate

The Radeon RX 6500 XT is a lot (about 262%) faster with regards to anti-aliasing than the GeForce GTX 465, and should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 50976 (262%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip 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 drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
