GeForce GTS 450 vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which has GPU core speed of 1015 MHz, and 4096 MB of DDR3 memory running at 1100 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTS 450 will be 64% faster than the Radeon R9 M375 in general, due to its greater bandwidth. (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 (more or less 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 a high screen resolution 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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number 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 higher this number, the better the card will be at handling 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 record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
