GeForce GTX Titan Black vs Nvidia Titan X


Intro

The GeForce GTX Titan Black has clock speeds of 889 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR5 memory. It features 2880 SPUs as well as 240 Texture Address Units and 48 Rasterization Operator Units.

Compare those specifications to the Nvidia Titan X, which uses a 16 nm design. nVidia has clocked the core frequency at 1417 MHz. The GDDR5X RAM is set to run at a speed of 1251 MHz on this specific model. It features 3584 SPUs as well as 224 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X will be 46% quicker than the GeForce GTX Titan Black overall, because of its higher data rate. (explain)

Nvidia Titan X 491520 MB/sec
GeForce GTX Titan Black 336000 MB/sec
Difference: 155520 (46%)

Texel Rate

The Nvidia Titan X should be quite a bit (approximately 49%) more effective at texture filtering than the GeForce GTX Titan Black. (explain)

Nvidia Titan X 317408 Mtexels/sec
GeForce GTX Titan Black 213360 Mtexels/sec
Difference: 104048 (49%)

Pixel Rate

The Nvidia Titan X should be much (approximately 219%) faster with regards to AA than the GeForce GTX Titan Black, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Nvidia Titan X 136032 Mpixels/sec
GeForce GTX Titan Black 42672 Mpixels/sec
Difference: 93360 (219%)

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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
