GeForce GT 340 vs Radeon RX 580

Intro

The GeForce GT 340 comes with clock speeds of 550 MHz on the GPU, and 850 MHz on the 512 MB of GDDR5 RAM. It features 96 SPUs along with 32 Texture Address Units and 8 ROPs.

Compare those specifications to the Radeon RX 580, which features core clock speeds of 1257 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs along with 144 Texture Address Units and 32 Rasterization Operator Units.

The Radeon RX 580 should in theory be a lot faster than the GeForce GT 340 overall. (explain)

Radeon RX 580 262144 MB/sec
GeForce GT 340 54400 MB/sec
Difference: 207744 (382%)

Texel Rate

The Radeon RX 580 is much (about 928%) better at anisotropic filtering than the GeForce GT 340. (explain)

Radeon RX 580 181008 Mtexels/sec
GeForce GT 340 17600 Mtexels/sec
Difference: 163408 (928%)

Pixel Rate

The Radeon RX 580 should be a lot (more or less 814%) more effective at FSAA than the GeForce GT 340, and also should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 580 40224 Mpixels/sec
GeForce GT 340 4400 Mpixels/sec
Difference: 35824 (814%)

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 max amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
