GeForce GT 240 GDDR5 1GB vs Radeon RX Vega 56

Intro

Compare that to the Radeon RX Vega 56, which features a clock speed of 1156 MHz and a HBM2 memory frequency of 1600 MHz. It also uses a 2048-bit memory bus, and uses a 14 nm design. It is made up of 3584 SPUs, 224 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 240 GDDR5 1GB		70 Watts
Radeon RX Vega 56		210 Watts
	Difference: 140 Watts (200%)

Memory Bandwidth

Theoretically speaking, the Radeon RX Vega 56 is 671% faster than the GeForce GT 240 GDDR5 1GB in general, because of its higher data rate. (explain)

Radeon RX Vega 56		419430 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 365030 (671%)

Texel Rate

The Radeon RX Vega 56 is quite a bit (about 1371%) better at anisotropic filtering than the GeForce GT 240 GDDR5 1GB. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 241344 (1371%)

Pixel Rate

The Radeon RX Vega 56 is quite a bit (approximately 1581%) better at AA than the GeForce GT 240 GDDR5 1GB, and should be able to handle higher resolutions better. (explain)

Radeon RX Vega 56		73984 Mpixels/sec
GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
	Difference: 69584 (1581%)

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 data (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once 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, High Dynamic Range and high resolutions.

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