GeForce RTX 4070 Ti vs Radeon R9 M385X

Intro

Compare that to the Radeon R9 M385X, which features a core clock speed of 1100 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce RTX 4070 Ti should be 438% faster than the Radeon R9 M385X overall, due to its higher bandwidth. (explain)

GeForce RTX 4070 Ti		516096 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 420096 (438%)

Texel Rate

The GeForce RTX 4070 Ti should be much (approximately 800%) better at texture filtering than the Radeon R9 M385X. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 492800 (800%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 4070 Ti is superior to the Radeon R9 M385X, and very much so. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 167200 (950%)

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 largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
