GeForce GTX 460 (OEM) vs Radeon RX 460


Intro

The GeForce GTX 460 (OEM) comes with core clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

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

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

Texel Rate

The Radeon RX 460 will be quite a bit (approximately 68%) faster with regards to texture 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 a high screen resolution is important to you, then the GeForce GTX 460 (OEM) is superior to the Radeon RX 460, but it probably won't make a huge difference. (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 maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
