GeForce GTX 1650 vs GeForce RTX 2080

Intro

The GeForce GTX 1650 features a GPU clock speed of 1485 MHz, and the 4096 MB of GDDR5 RAM is set to run at 8000 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 Texture Address Units, and 32 ROPs.

Compare those specs to the GeForce RTX 2080, which makes use of a 12 nm design. nVidia has clocked the core speed at 1515 MHz. The GDDR6 memory runs at a speed of 14 MHz on this model. It features 2944 SPUs along with 184 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650 75 Watts
GeForce RTX 2080 215 Watts
Difference: 140 Watts (187%)

Memory Bandwidth

The GeForce RTX 2080 should in theory be much faster than the GeForce GTX 1650 overall. (explain)

GeForce RTX 2080 458752 MB/sec
GeForce GTX 1650 131072 MB/sec
Difference: 327680 (250%)

Texel Rate

The GeForce RTX 2080 will be a lot (more or less 235%) faster with regards to AF than the GeForce GTX 1650. (explain)

GeForce RTX 2080 278760 Mtexels/sec
GeForce GTX 1650 83160 Mtexels/sec
Difference: 195600 (235%)

Pixel Rate

The GeForce RTX 2080 is quite a bit (about 104%) more effective at full screen anti-aliasing than the GeForce GTX 1650, and should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce RTX 2080 96960 Mpixels/sec
GeForce GTX 1650 47520 Mpixels/sec
Difference: 49440 (104%)

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: Bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the 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 amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
