GeForce GTX 460 SE vs Radeon RX 460


Intro

The GeForce GTX 460 SE uses a 40 nm design. nVidia has set the core frequency at 650 MHz. The GDDR5 RAM is set to run at a speed of 850 MHz on this model. It features 288 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the Radeon RX 460, which uses a 14 nm design. AMD has set the core frequency at 1090 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this specific model. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

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

Performance-wise, the Radeon RX 460 should theoretically be just a bit superior to the GeForce GTX 460 SE in general. (explain)

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

Texel Rate

The Radeon RX 460 should be much (more or less 96%) faster with regards to anisotropic filtering 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 using lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is superior to the Radeon RX 460, but not by far. (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 max amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied 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 better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated 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 filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
