GeForce GTX Titan vs Radeon RX 6650 XT

Intro

The GeForce GTX Titan has a core clock frequency of 837 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 384-bit bus, and makes use of a 28 nm design. It features 2688 SPUs, 224 TAUs, and 48 ROPs.

Compare all that to the Radeon RX 6650 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 2055 MHz. The GDDR6 RAM works at a speed of 2190 MHz on this particular card. It features 2048 SPUs as well as 128 TAUs and 64 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
