GeForce GT 240 GDDR5 1GB vs Radeon RX Vega 64

Intro

Compare all of that to the Radeon RX Vega 64, which makes use of a 14 nm design. AMD has set the core speed at 1247 MHz. The HBM2 memory works at a frequency of 1890 MHz on this specific card. It features 4096 SPUs as well as 256 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 240 GDDR5 1GB		70 Watts
Radeon RX Vega 64		295 Watts
	Difference: 225 Watts (321%)

Memory Bandwidth

In theory, the Radeon RX Vega 64 should be 811% faster than the GeForce GT 240 GDDR5 1GB overall, because of its greater data rate. (explain)

Radeon RX Vega 64		495411 MB/sec
GeForce GT 240 GDDR5 1GB		54400 MB/sec
	Difference: 441011 (811%)

Texel Rate

The Radeon RX Vega 64 is quite a bit (approximately 1714%) faster with regards to texture filtering than the GeForce GT 240 GDDR5 1GB. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 301632 (1714%)

Pixel Rate

The Radeon RX Vega 64 will be quite a bit (about 1714%) better at anti-aliasing than the GeForce GT 240 GDDR5 1GB, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
	Difference: 75408 (1714%)

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 (counted in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core 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 output 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 reach the max fill rate.
