GeForce GTX 1070 vs GeForce RTX 3050

Intro

Compare those specifications to the GeForce RTX 3050, which uses a 8 nm design. nVidia has clocked the core frequency at 1552 MHz. The GDDR6 memory runs at a frequency of 1750 MHz on this model. It features 2560 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

GeForce RTX 3050		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The GeForce GTX 1070 should be a lot (approximately 46%) faster with regards to AF than the GeForce RTX 3050. (explain)

GeForce GTX 1070		180720 Mtexels/sec
GeForce RTX 3050		124160 Mtexels/sec
	Difference: 56560 (46%)

Pixel Rate

The GeForce GTX 1070 should be much (more or less 94%) more effective at FSAA than the GeForce RTX 3050, and also will be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 1070		96384 Mpixels/sec
GeForce RTX 3050		49664 Mpixels/sec
	Difference: 46720 (94%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at 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 graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the potential to reach the maximum fill rate.
