GeForce GTX 465 vs Radeon RX 460


Intro

The GeForce GTX 465 comes with clock speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 RAM. It features 352 SPUs along with 44 Texture Address Units and 32 ROPs.

Compare those specifications to the Radeon RX 460, which has a clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It features 896 SPUs, 56 TAUs, and 16 Raster Operation 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 should theoretically perform a small bit faster than the GeForce GTX 465 overall. (explain)

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

Texel Rate

The Radeon RX 460 will be much (approximately 129%) more effective at texture filtering 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 lots of anti-aliasing is important to you, then the GeForce GTX 465 is a better choice, but not by far. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 are applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
