GeForce GTX 465 vs Radeon RX 550

Intro

The GeForce GTX 465 has a core clock speed of 607 MHz and a GDDR5 memory frequency of 802 MHz. It also makes use of a 256-bit memory bus, and uses a 40 nm design. It is comprised of 352 SPUs, 44 TAUs, and 32 ROPs.

Compare those specs to the Radeon RX 550, which has a clock speed of 1100 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit memory bus, and uses a 14 nm design. It is made up of 512 SPUs, 32 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
