GeForce GTX 460 1GB vs Radeon RX 460


Intro

The GeForce GTX 460 1GB comes with a clock speed of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It is made up of 336 SPUs, 56 TAUs, and 32 ROPs.

Compare all that to the Radeon RX 460, which features core clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Radeon RX 460 75 Watts
GeForce GTX 460 1GB 160 Watts
Difference: 85 Watts (113%)

Memory Bandwidth

The GeForce GTX 460 1GB, in theory, should perform a small bit faster than the Radeon RX 460 overall. (explain)

GeForce GTX 460 1GB 115200 MB/sec
Radeon RX 460 112000 MB/sec
Difference: 3200 (3%)

Texel Rate

The Radeon RX 460 should be quite a bit (about 61%) better at texture filtering than the GeForce GTX 460 1GB. (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GTX 460 1GB 37800 Mtexels/sec
Difference: 23240 (61%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 1GB is the winner, by far. (explain)

GeForce GTX 460 1GB 21600 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 4160 (24%)

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 information (counted in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that 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 number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
