GeForce GTX 950 vs Radeon RX 460

Intro

The GeForce GTX 950 makes use of a 28 nm design. nVidia has clocked the core speed at 1024 MHz. The GDDR5 memory is set to run at a speed of 1652 MHz on this particular model. It features 768 SPUs along with 48 TAUs and 32 ROPs.

Compare those specs to the Radeon RX 460, which comes with GPU clock speed of 1090 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

The Radeon RX 460 will be much (approximately 24%) faster with regards to texture filtering than the GeForce GTX 950. (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GTX 950 49152 Mtexels/sec
Difference: 11888 (24%)

Pixel Rate

The GeForce GTX 950 will be quite a bit (about 88%) more effective at full screen anti-aliasing than the Radeon RX 460, and should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 950 32768 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 15328 (88%)

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 largest amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.

Hi, which brand are we comparing here, please?
I would like to know this detail also.

MikEms says:

Just default specifications for any card, however most brands do offer overclocked versions.
