GeForce GT 450 (OEM) vs Radeon R7 M265

Intro

Compare all of that to the Radeon R7 M265, which makes use of a 28 nm design. AMD has set the core speed at 725 MHz. The DDR3 RAM works at a speed of 1000 MHz on this particular model. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 450 (OEM) should be 200% quicker than the Radeon R7 M265 in general, due to its greater bandwidth. (explain)

GeForce GT 450 (OEM)		96000 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 64000 (200%)

Texel Rate

The GeForce GT 450 (OEM) will be a bit (about 9%) more effective at AF than the Radeon R7 M265. (explain)

GeForce GT 450 (OEM)		18960 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 1560 (9%)

Pixel Rate

The GeForce GT 450 (OEM) should be quite a bit (more or less 227%) faster with regards to AA than the Radeon R7 M265, and will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 13160 (227%)

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 maximum amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 processed in one second. This figure is calculated by multiplying the total amount of texture units 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
