GeForce GTX 1650 vs Radeon HD 4850 X2 512MB

Intro

The GeForce GTX 1650 uses a 12 nm design. nVidia has clocked the core frequency at 1485 MHz. The GDDR5 RAM is set to run at a speed of 8000 MHz on this specific card. It features 896 SPUs along with 56 Texture Address Units and 32 ROPs.

Compare all that to the Radeon HD 4850 X2 512MB, which has GPU core speed of 625 MHz, and 512 MB of GDDR3 memory running at 993 MHz through a 256-bit bus. It also features 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce GTX 1650 83160 Mtexels/sec
Radeon HD 4850 X2 512MB 50000 Mtexels/sec
Difference: 33160 (66%)

Pixel Rate

The GeForce GTX 1650 should be quite a bit (more or less 138%) more effective at full screen anti-aliasing than the Radeon HD 4850 X2 512MB, and will be able to handle higher screen resolutions better. (explain)

GeForce GTX 1650 47520 Mpixels/sec
Radeon HD 4850 X2 512MB 20000 Mpixels/sec
Difference: 27520 (138%)

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: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
