GeForce GT 450 (OEM) vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 RAM works at a speed of 1500 MHz on this particular card. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R9 M385X should be much (about 225%) faster with regards to AF 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

The GeForce GT 450 (OEM) is a little bit (about 8%) faster with regards to full screen anti-aliasing than the Radeon R9 M385X, and also should be able to handle higher resolutions without slowing down too much. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. It's 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 it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card 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 processed per second.

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