GeForce GTX 465 vs Radeon RX 6950 XT

Intro

Compare all that to the Radeon RX 6950 XT, which has GPU core speed of 1925 MHz, and 16384 MB of GDDR6 RAM running at 2250 MHz through a 256-bit bus. It also features 5120 Stream Processors, 320 Texture Address Units, and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 465		200 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 135 Watts (68%)

Memory Bandwidth

In theory, the Radeon RX 6950 XT is 475% quicker than the GeForce GTX 465 in general, due to its greater data rate. (explain)

Radeon RX 6950 XT		589824 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 487232 (475%)

Texel Rate

The Radeon RX 6950 XT will be much (about 2206%) more effective at texture filtering than the GeForce GTX 465. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 589292 (2206%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6950 XT is the winner, and very much so. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 226976 (1169%)

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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling 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 calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. 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.
