VS

Radeon RX 460 vs Radeon RX 5500

Intro

The Radeon RX 460 features a GPU clock speed of 1090 MHz, and the 4096 MB of GDDR5 RAM runs at 1750 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon RX 5500, which comes with core speeds of 1670 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR6 RAM. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 75 Watts
Radeon RX 5500 150 Watts
Difference: 75 Watts (100%)

Memory Bandwidth

As far as performance goes, the Radeon RX 5500 should theoretically be much superior to the Radeon RX 460 in general. (explain)

Radeon RX 5500 229376 MB/sec
Radeon RX 460 112000 MB/sec
Difference: 117376 (105%)

Texel Rate

The Radeon RX 5500 should be a lot (more or less 141%) more effective at texture filtering than the Radeon RX 460. (explain)

Radeon RX 5500 146960 Mtexels/sec
Radeon RX 460 61040 Mtexels/sec
Difference: 85920 (141%)

Pixel Rate

The Radeon RX 5500 will be quite a bit (approximately 206%) better at AA than the Radeon RX 460, and should be able to handle higher screen resolutions better. (explain)

Radeon RX 5500 53440 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 36000 (206%)

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 (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses 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, High Dynamic Range 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 by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
