GeForce GTX 1070 vs Radeon RX 6650 XT

Intro

The GeForce GTX 1070 uses a 16 nm design. nVidia has set the core frequency at 1506 MHz. The GDDR5 memory works at a frequency of 2000 MHz on this specific model. It features 1920 SPUs as well as 120 Texture Address Units and 64 ROPs.

Compare those specifications to the Radeon RX 6650 XT, which features a clock frequency of 2055 MHz and a GDDR6 memory speed of 2190 MHz. It also makes use of a 128-bit memory bus, and uses a 7 nm design. It is made up of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
