GeForce GTS 450 1GB vs Radeon R9 M375X

Intro

Compare those specifications to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M375X should in theory be quite a bit superior to the GeForce GTS 450 1GB in general. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce GTS 450 1GB		57728 MB/sec
	Difference: 14272 (25%)

Texel Rate

The Radeon R9 M375X will be a lot (more or less 62%) faster with regards to anisotropic filtering than the GeForce GTS 450 1GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GTS 450 1GB		25056 Mtexels/sec
	Difference: 15544 (62%)

Pixel Rate

The Radeon R9 M375X should be quite a bit (more or less 30%) more effective at AA than the GeForce GTS 450 1GB, and also will be capable of handling higher screen resolutions better. (explain)

Radeon R9 M375X		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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 - the lower the bandwidth is, the lower the potential to reach the max fill rate.
