GeForce GTS 450 vs Radeon R9 M375

Intro

The GeForce GTS 450 has clock speeds of 783 MHz on the GPU, and 902 MHz on the 512 MB of GDDR5 memory. It features 192 SPUs as well as 32 Texture Address Units and 16 ROPs.

Compare all of that to the Radeon R9 M375, which makes use of a 28 nm design. AMD has set the core frequency at 1015 MHz. The DDR3 RAM works at a frequency of 1100 MHz on this specific model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTS 450, in theory, should be much faster than the Radeon R9 M375 overall. (explain)

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

Texel Rate

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

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

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M375 is superior to the GeForce GTS 450, and very much so. (explain)

Radeon R9 M375 16240 Mpixels/sec
GeForce GTS 450 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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant 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 maximum fill rate.
