GeForce RTX 3070 vs Radeon RX 5700

Intro

Compare that to the Radeon RX 5700, which comes with a core clock frequency of 1465 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 256-bit bus, and uses a 7 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
GeForce RTX 3070		220 Watts
	Difference: 40 Watts (22%)

Memory Bandwidth

In theory, the Radeon RX 5700 should be -100% quicker than the GeForce RTX 3070 overall, due to its greater bandwidth. (explain)

Radeon RX 5700		458752 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 458752 (-100%)

Texel Rate

The GeForce RTX 3070 will be quite a bit (approximately 31%) better at anisotropic filtering than the Radeon RX 5700. (explain)

GeForce RTX 3070		276000 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 65040 (31%)

Pixel Rate

The GeForce RTX 3070 will be quite a bit (about 54%) better at AA than the Radeon RX 5700, and should be able to handle higher screen resolutions better. (explain)

GeForce RTX 3070		144000 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 50240 (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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher 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 maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
