GeForce GTX 465 vs Radeon RX 460

Intro

The GeForce GTX 465 comes with a clock frequency of 607 MHz and a GDDR5 memory speed of 802 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It is comprised of 352 SPUs, 44 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon RX 460, which uses a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this specific model. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 75 Watts
GeForce GTX 465 200 Watts
Difference: 125 Watts (167%)

Memory Bandwidth

The Radeon RX 460, in theory, should be a little bit faster than the GeForce GTX 465 in general. (explain)

Radeon RX 460 112000 MB/sec
GeForce GTX 465 102592 MB/sec
Difference: 9408 (9%)

Texel Rate

The Radeon RX 460 is quite a bit (approximately 129%) more effective at AF than the GeForce GTX 465. (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 34332 (129%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 465 is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 465 19424 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 1984 (11%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
