GeForce GT 430 1GB vs Radeon RX 460

Intro

The GeForce GT 430 1GB has a core clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It features 96 SPUs, 16 TAUs, and 4 ROPs.

Compare those specs to the Radeon RX 460, which features a clock frequency of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 14 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 1GB 60 Watts
Radeon RX 460 75 Watts
Difference: 15 Watts (25%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 should be much faster than the GeForce GT 430 1GB overall. (explain)

Radeon RX 460 112000 MB/sec
GeForce GT 430 1GB 28800 MB/sec
Difference: 83200 (289%)

Texel Rate

The Radeon RX 460 is quite a bit (more or less 445%) more effective at texture filtering than the GeForce GT 430 1GB. (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GT 430 1GB 11200 Mtexels/sec
Difference: 49840 (445%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 460 is a better choice, by far. (explain)

Radeon RX 460 17440 Mpixels/sec
GeForce GT 430 1GB 2800 Mpixels/sec
Difference: 14640 (523%)

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 data (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
