GeForce GTX 1650 vs Radeon HD 4890 1GB

Intro

The GeForce GTX 1650 comes with a GPU core clock speed of 1485 MHz, and the 4096 MB of GDDR5 RAM runs at 8000 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 Texture Address Units, and 32 ROPs.

Compare all that to the Radeon HD 4890 1GB, which has a core clock speed of 1000 MHz and a GDDR5 memory speed of 975 MHz. It also uses a 256-bit memory bus, and makes use of a 55 nm design. It features 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Texel Rate

The GeForce GTX 1650 should be quite a bit (approximately 108%) more effective at AF than the Radeon HD 4890 1GB. (explain)

GeForce GTX 1650 83160 Mtexels/sec
Radeon HD 4890 1GB 40000 Mtexels/sec
Difference: 43160 (108%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1650 is a better choice, by a large margin. (explain)

GeForce GTX 1650 47520 Mpixels/sec
Radeon HD 4890 1GB 16000 Mpixels/sec
Difference: 31520 (197%)

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 largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher 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 most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
