GeForce GTX Titan X vs Radeon RX Vega 56

Intro

Compare all of that to the Radeon RX Vega 56, which uses a 14 nm design. AMD has set the core speed at 1156 MHz. The HBM2 RAM is set to run at a speed of 1600 MHz on this particular model. It features 3584 SPUs along with 224 Texture Address Units and 64 ROPs.

GeForce GTX Titan X		192000 Mtexels/sec
	Difference: 66944 (35%)

Pixel Rate

The GeForce GTX Titan X should be quite a bit (more or less 30%) more effective at anti-aliasing than the Radeon RX Vega 56, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 22016 (30%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
