Nvidia Titan X vs Radeon HD 4750

Intro

Compare those specifications to the Radeon HD 4750, which uses a 40 nm design. AMD has clocked the core frequency at 730 MHz. The GDDR5 RAM works at a speed of 800 MHz on this card. It features 640(128x5) SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4750		75 Watts
Nvidia Titan X		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

As far as performance goes, the Nvidia Titan X should in theory be much superior to the Radeon HD 4750 in general. (explain)

Nvidia Titan X		491520 MB/sec
Radeon HD 4750		51200 MB/sec
	Difference: 440320 (860%)

Texel Rate

The Nvidia Titan X will be quite a bit (approximately 1259%) better at texture filtering than the Radeon HD 4750. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon HD 4750		23360 Mtexels/sec
	Difference: 294048 (1259%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Nvidia Titan X is superior to the Radeon HD 4750, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon HD 4750		11680 Mpixels/sec
	Difference: 124352 (1065%)

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: Bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
