GeForce GT 240 GDDR5 1GB vs Radeon RX Vega 56

Intro

Compare all that to the Radeon RX Vega 56, which has a core clock frequency of 1156 MHz and a HBM2 memory frequency of 1600 MHz. It also makes use of a 2048-bit memory bus, and makes use of a 14 nm design. It is comprised of 3584 SPUs, 224 Texture Address Units, and 64 Raster Operation Units.

	Difference: 365030 (671%)

Texel Rate

The Radeon RX Vega 56 is a lot (about 1371%) faster with regards to 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

If using a high resolution is important to you, then the Radeon RX Vega 56 is a better choice, by far. (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 (in units of MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
