GeForce GT 240 GDDR5 1GB vs Radeon R7 M265

Intro

Compare those specs to the Radeon R7 M265, which comes with GPU core speed of 725 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GT 240 GDDR5 1GB should theoretically be quite a bit superior to the Radeon R7 M265 overall. (explain)

GeForce GT 240 GDDR5 1GB		54400 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 22400 (70%)

Texel Rate

The GeForce GT 240 GDDR5 1GB is a little bit (about 1%) faster with regards to AF than the Radeon R7 M265. (explain)

GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 200 (1%)

Pixel Rate

The Radeon R7 M265 should be much (approximately 32%) more effective at AA than the GeForce GT 240 GDDR5 1GB, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R7 M265		5800 Mpixels/sec
GeForce GT 240 GDDR5 1GB		4400 Mpixels/sec
	Difference: 1400 (32%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
