Nvidia Titan X vs Radeon Vega Frontier Edition

Intro

Compare all that to the Radeon Vega Frontier Edition, which has a clock speed of 1382 MHz and a HBM2 memory frequency of 1890 MHz. It also uses a 2048-bit memory bus, and makes use of a 14 nm design. It is made up of 4096 SPUs, 256 Texture Address Units, and 64 ROPs.

Nvidia Titan X		317408 Mtexels/sec
	Difference: 36384 (11%)

Pixel Rate

The Nvidia Titan X will be a lot (approximately 54%) better at AA than the Radeon Vega Frontier Edition, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon Vega Frontier Edition		88448 Mpixels/sec
	Difference: 47584 (54%)

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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
