GeForce GTX 1650 vs Radeon HD 7870

Intro

The GeForce GTX 1650 uses a 12 nm design. nVidia has set the core speed at 1485 MHz. The GDDR5 RAM is set to run at a frequency of 8000 MHz on this particular model. It features 896 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.

Compare those specs to the Radeon HD 7870, which uses a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM is set to run at a speed of 1200 MHz on this particular card. It features 1280 SPUs along with 80 TAUs and 32 Rasterization Operator Units.

GeForce GTX 1650 83160 Mtexels/sec
Radeon HD 7870 80000 Mtexels/sec
Difference: 3160 (4%)

Pixel Rate

The GeForce GTX 1650 should be a lot (about 49%) better at FSAA than the Radeon HD 7870, and should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 1650 47520 Mpixels/sec
Radeon HD 7870 32000 Mpixels/sec
Difference: 15520 (49%)

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 (measured in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can 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 Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
