GeForce RTX 4070 Ti vs Radeon RX 5700

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
GeForce RTX 4070 Ti		285 Watts
	Difference: 105 Watts (58%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 4070 Ti will be 13% faster than the Radeon RX 5700 in general, because of its higher bandwidth. (explain)

GeForce RTX 4070 Ti		516096 MB/sec
Radeon RX 5700		458752 MB/sec
	Difference: 57344 (13%)

Texel Rate

The GeForce RTX 4070 Ti should be a lot (about 163%) more effective at texture filtering than the Radeon RX 5700. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 343440 (163%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 4070 Ti is superior to the Radeon RX 5700, by a large margin. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 91040 (97%)

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 transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
