GeForce RTX 4070 Ti vs Radeon RX Vega 64

Intro

Compare those specs to the Radeon RX Vega 64, which has a core clock speed of 1247 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 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 4070 Ti		285 Watts
Radeon RX Vega 64		295 Watts
	Difference: 10 Watts (4%)

Memory Bandwidth

In theory, the GeForce RTX 4070 Ti is 4% faster than the Radeon RX Vega 64 overall, due to its higher data rate. (explain)

GeForce RTX 4070 Ti		516096 MB/sec
Radeon RX Vega 64		495411 MB/sec
	Difference: 20685 (4%)

Texel Rate

The GeForce RTX 4070 Ti should be much (more or less 74%) more effective at anisotropic filtering than the Radeon RX Vega 64. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon RX Vega 64		319232 Mtexels/sec
	Difference: 235168 (74%)

Pixel Rate

The GeForce RTX 4070 Ti will be a lot (more or less 132%) faster with regards to AA than the Radeon RX Vega 64, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
Radeon RX Vega 64		79808 Mpixels/sec
	Difference: 104992 (132%)

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 MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
