GeForce GTS 450 1GB vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which uses a 28 nm design. AMD has set the core frequency at 1015 MHz. The DDR3 memory is set to run at a frequency of 1100 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTS 450 1GB should perform quite a bit faster than the Radeon R9 M375 overall. (explain)

GeForce GTS 450 1GB		57728 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 22528 (64%)

Texel Rate

The Radeon R9 M375 should be quite a bit (approximately 62%) more effective at texture filtering than the GeForce GTS 450 1GB. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GTS 450 1GB		25056 Mtexels/sec
	Difference: 15544 (62%)

Pixel Rate

The Radeon R9 M375 should be a lot (approximately 30%) faster with regards to anti-aliasing than the GeForce GTS 450 1GB, and should be able to handle higher screen resolutions better. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GTS 450 1GB		12528 Mpixels/sec
	Difference: 3712 (30%)

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 max amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its 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 sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
