GeForce GTX 550 Ti vs Radeon RX 470 4GB

Intro

The GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has clocked the core frequency at 900 MHz. The GDDR5 memory runs at a frequency of 1026 MHz on this model. It features 192 SPUs along with 32 TAUs and 24 ROPs.

Compare that to the Radeon RX 470 4GB, which features GPU core speed of 926 MHz, and 4096 MB of GDDR5 memory set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the 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 maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
