GeForce GTS 450 vs Radeon R9 M370X

Intro

The GeForce GTS 450 features 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 TAUs and 16 ROPs.

Compare those specifications to the Radeon R9 M370X, which comes with a clock frequency of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M370X should in theory be quite a bit better than the GeForce GTS 450 overall. (explain)

Radeon R9 M370X 72000 MB/sec
GeForce GTS 450 57728 MB/sec
Difference: 14272 (25%)

Texel Rate

The Radeon R9 M370X should be quite a bit (about 28%) more effective at AF than the GeForce GTS 450. (explain)

Radeon R9 M370X 32000 Mtexels/sec
GeForce GTS 450 25056 Mtexels/sec
Difference: 6944 (28%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M370X is superior to the GeForce GTS 450, though not by far. (explain)

Radeon R9 M370X 12800 Mpixels/sec
GeForce GTS 450 12528 Mpixels/sec
Difference: 272 (2%)

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 largest amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 memory bandwidth is, the lower the potential to reach the maximum fill rate.
