GeForce 9400 GT 256MB vs Nvidia Titan Xp

Intro

Compare those specifications to the Nvidia Titan Xp, which uses a 16 nm design. nVidia has set the core frequency at 1582 MHz. The GDDR5X RAM runs at a speed of 1426 MHz on this particular model. It features 3840 SPUs along with 240 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9400 GT 256MB		50 Watts
Nvidia Titan Xp		250 Watts
	Difference: 200 Watts (400%)

Memory Bandwidth

The Nvidia Titan Xp should theoretically perform a lot faster than the GeForce 9400 GT 256MB in general. (explain)

Nvidia Titan Xp		560845 MB/sec
GeForce 9400 GT 256MB		12800 MB/sec
	Difference: 548045 (4282%)

Texel Rate

The Nvidia Titan Xp is quite a bit (about 8529%) more effective at anisotropic filtering than the GeForce 9400 GT 256MB. (explain)

Nvidia Titan Xp		379680 Mtexels/sec
GeForce 9400 GT 256MB		4400 Mtexels/sec
	Difference: 375280 (8529%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Nvidia Titan Xp is a better choice, and very much so. (explain)

Nvidia Titan Xp		151872 Mpixels/sec
GeForce 9400 GT 256MB		2200 Mpixels/sec
	Difference: 149672 (6803%)

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 data (measured in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 are processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
