GeForce GT 450 (OEM) vs Radeon R9 M385X

Intro

The GeForce GT 450 (OEM) features core speeds of 790 MHz on the GPU, and 1000 MHz on the 1536 MB of GDDR5 memory. It features 144 SPUs along with 24 TAUs and 24 ROPs.

Compare all that to the Radeon R9 M385X, which has a GPU core clock speed of 1100 MHz, and 4096 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon R9 M385X should be a lot (about 225%) more effective at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce GT 450 (OEM) 18960 Mtexels/sec
Difference: 42640 (225%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GT 450 (OEM) is a better choice, though only just barely. (explain)

GeForce GT 450 (OEM) 18960 Mpixels/sec
Radeon R9 M385X 17600 Mpixels/sec
Difference: 1360 (8%)

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 maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
