GeForce GTS 450 vs Radeon R9 M375

Intro

The GeForce GTS 450 features a clock speed of 783 MHz and a GDDR5 memory frequency of 902 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is made up of 192 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare those specs to the Radeon R9 M375, which makes use of a 28 nm design. AMD has clocked the core speed at 1015 MHz. The DDR3 RAM is set to run at a frequency of 1100 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTS 450 should in theory be a lot superior to the Radeon R9 M375 in general. (explain)

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

Texel Rate

The Radeon R9 M375 should be much (approximately 62%) faster with regards to 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 running with 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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its 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 speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
