Nvidia Titan X vs Radeon R9 290

Intro

The Nvidia Titan X uses a 16 nm design. nVidia has clocked the core speed at 1417 MHz. The GDDR5X memory runs at a speed of 1251 MHz on this card. It features 3584 SPUs along with 224 TAUs and 96 Rasterization Operator Units.

Compare all of that to the Radeon R9 290, which features core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 RAM. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out 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 filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
