GeForce GTX 460 SE vs Radeon RX 460

Intro

The GeForce GTX 460 SE features a GPU core speed of 650 MHz, and the 1024 MB of GDDR5 memory runs at 850 MHz through a 256-bit bus. It also is comprised of 288 SPUs, 48 Texture Address Units, and 32 ROPs.

Compare those specifications to the Radeon RX 460, which features GPU core speed of 1090 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 75 Watts
GeForce GTX 460 SE 150 Watts
Difference: 75 Watts (100%)

Memory Bandwidth

In theory, the Radeon RX 460 is 3% faster than the GeForce GTX 460 SE overall, due to its greater data rate. (explain)

Radeon RX 460 112000 MB/sec
GeForce GTX 460 SE 108800 MB/sec
Difference: 3200 (3%)

Texel Rate

The Radeon RX 460 will be a lot (approximately 96%) faster with regards to AF than the GeForce GTX 460 SE. (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GTX 460 SE 31200 Mtexels/sec
Difference: 29840 (96%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 460 SE is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 460 SE 20800 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 3360 (19%)

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 largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. 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 rate also depends on many 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.
