GeForce RTX 4070 Ti vs Radeon RX Vega 64

Intro

Compare those specifications to the Radeon RX Vega 64, which uses a 14 nm design. AMD has clocked the core frequency at 1247 MHz. The HBM2 memory is set to run at a frequency of 1890 MHz on this model. It features 4096 SPUs as well as 256 TAUs and 64 ROPs.

The GeForce RTX 4070 Ti should be quite a bit (more or less 74%) faster with regards to texture 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%) better at FSAA than the Radeon RX Vega 64, and should be capable of handling higher screen 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 max amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of 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.
