GeForce RTX 2070 vs Radeon RX 5700

Intro

Compare those specs to the Radeon RX 5700, which comes with a clock speed of 1465 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 256-bit bus, and uses a 7 nm design. It is made up of 2304 SPUs, 144 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070		175 Watts
Radeon RX 5700		180 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon RX 5700 should be a small bit (more or less 4%) better at texture filtering than the GeForce RTX 2070. (explain)

Radeon RX 5700		210960 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 7920 (4%)

Pixel Rate

The Radeon RX 5700 should be a bit (more or less 4%) better at FSAA than the GeForce RTX 2070, and also should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 5700		93760 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 3520 (4%)

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 (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should 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 AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
