GeForce GTS 450 1GB vs Nvidia Titan X

Intro

Compare that to the Nvidia Titan X, which makes use of a 16 nm design. nVidia has clocked the core speed at 1417 MHz. The GDDR5X RAM runs at a speed of 1251 MHz on this particular card. It features 3584 SPUs as well as 224 Texture Address Units and 96 ROPs.

GeForce GTS 450 1GB		57728 MB/sec
	Difference: 433792 (751%)

Texel Rate

The Nvidia Titan X will be much (about 1167%) more effective at AF than the GeForce GTS 450 1GB. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTS 450 1GB		25056 Mtexels/sec
	Difference: 292352 (1167%)

Pixel Rate

The Nvidia Titan X will be quite a bit (more or less 986%) faster with regards to AA than the GeForce GTS 450 1GB, and should be capable of handling higher resolutions without slowing down too much. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTS 450 1GB		12528 Mpixels/sec
	Difference: 123504 (986%)

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 maximum amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
