GeForce RTX 4070 Ti vs Radeon RX Vega 64

Intro

Compare those specs to the Radeon RX Vega 64, which uses a 14 nm design. AMD has set the core speed at 1247 MHz. The HBM2 memory works at a frequency of 1890 MHz on this specific card. It features 4096 SPUs as well as 256 Texture Address Units and 64 Rasterization Operator 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

Theoretically speaking, the GeForce RTX 4070 Ti will be 4% quicker than the Radeon RX Vega 64 in general, due to its greater bandwidth. (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 (about 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 quite a bit (more or less 132%) better at anti-aliasing than the Radeon RX Vega 64, and also capable of handling higher resolutions without slowing down too much. (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 maximum amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
