GeForce GTX 465 vs Radeon RX 590

Intro

Compare those specifications to the Radeon RX 590, which features GPU core speed of 1469 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also features 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

GeForce GTX 465		102592 MB/sec
	Difference: 159552 (156%)

Texel Rate

The Radeon RX 590 is much (about 692%) better at anisotropic filtering than the GeForce GTX 465. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 184828 (692%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 590 is the winner, by far. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 27584 (142%)

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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
