GeForce GT 340 vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which has a clock frequency of 1717 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 7 nm design. It is made up of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
Radeon RX 5500 XT		130 Watts
	Difference: 61 Watts (88%)

Memory Bandwidth

In theory, the Radeon RX 5500 XT should be 322% faster than the GeForce GT 340 in general, because of its higher data rate. (explain)

Radeon RX 5500 XT		229376 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 174976 (322%)

Texel Rate

The Radeon RX 5500 XT is much (more or less 759%) faster with regards to texture filtering than the GeForce GT 340. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 133496 (759%)

Pixel Rate

The Radeon RX 5500 XT should be quite a bit (approximately 1149%) better at FSAA than the GeForce GT 340, and also able to handle higher resolutions more effectively. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 50544 (1149%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
