VS

Radeon HD 4870 X2 vs Radeon RX 5500

Intro

The Radeon HD 4870 X2 makes use of a 55 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory runs at a speed of 900 MHz on this specific card. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Compare those specs to the Radeon RX 5500, which comes with a core clock speed of 1670 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 128-bit bus, and uses a 7 nm design. It is made up of 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 150 Watts
Radeon HD 4870 X2 350 Watts
Difference: 200 Watts (133%)

Memory Bandwidth

In theory, the Radeon HD 4870 X2 should be 0% quicker than the Radeon RX 5500 in general, because of its higher data rate. (explain)

Radeon HD 4870 X2 230400 MB/sec
Radeon RX 5500 229376 MB/sec
Difference: 1024 (0%)

Texel Rate

The Radeon RX 5500 will be much (about 145%) faster with regards to texture filtering than the Radeon HD 4870 X2. (explain)

Radeon RX 5500 146960 Mtexels/sec
Radeon HD 4870 X2 60000 Mtexels/sec
Difference: 86960 (145%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5500 is superior to the Radeon HD 4870 X2, and very much so. (explain)

Radeon RX 5500 53440 Mpixels/sec
Radeon HD 4870 X2 24000 Mpixels/sec
Difference: 29440 (123%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
