GeForce GTX 460 (OEM) vs Radeon RX 460

Intro

The GeForce GTX 460 (OEM) has core speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.

Compare those specs to the Radeon RX 460, which features GPU core speed of 1090 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also features 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 should be a little bit faster than the GeForce GTX 460 (OEM) overall. (explain)

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

Texel Rate

The Radeon RX 460 should be a lot (approximately 68%) faster with regards to anisotropic filtering than the GeForce GTX 460 (OEM). (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GTX 460 (OEM) 36400 Mtexels/sec
Difference: 24640 (68%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 (OEM) is superior to the Radeon RX 460, not by a very large margin though. (explain)

GeForce GTX 460 (OEM) 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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per 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 - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
