Radeon RX 460 2GB vs Radeon VII

Intro

Compare those specifications to the Radeon VII, which features a core clock speed of 1400 MHz and a HBM2 memory speed of 1000 MHz. It also makes use of a 4096-bit memory bus, and uses a 7 nm design. It is comprised of 3840 SPUs, 240 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
Radeon VII		295 Watts
	Difference: 220 Watts (293%)

Memory Bandwidth

Theoretically, the Radeon VII should perform much faster than the Radeon RX 460 2GB overall. (explain)

Radeon VII		1048576 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 936576 (836%)

Texel Rate

The Radeon VII is much (approximately 450%) faster with regards to AF than the Radeon RX 460 2GB. (explain)

Radeon VII		336000 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 274960 (450%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon VII is superior to the Radeon RX 460 2GB, and very much so. (explain)

Radeon VII		89600 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 72160 (414%)

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 (in units of MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
