GeForce GTX Titan X vs Radeon R9 295X2

Intro

The GeForce GTX Titan X features core speeds of 1000 MHz on the GPU, and 1750 MHz on the 12288 MB of GDDR5 memory. It features 3072 SPUs along with 192 TAUs and 96 ROPs.

Compare all of that to the Radeon R9 295X2, which features a core clock speed of 1018 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 512-bit bus, and makes use of a 28 nm design. It is made up of 2816 SPUs, 176 TAUs, and 64 Raster Operation Units.

GeForce GTX Titan X 336000 MB/sec
Difference: 304000 (90%)

Texel Rate

The Radeon R9 295X2 is quite a bit (about 87%) more effective at texture filtering than the GeForce GTX Titan X. (explain)

Radeon R9 295X2 358336 Mtexels/sec
GeForce GTX Titan X 192000 Mtexels/sec
Difference: 166336 (87%)

Pixel Rate

The Radeon R9 295X2 is much (more or less 36%) better at FSAA than the GeForce GTX Titan X, and capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 295X2 130304 Mpixels/sec
GeForce GTX Titan X 96000 Mpixels/sec
Difference: 34304 (36%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling 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 that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

It's funny that nVidia even tries to sell the Titan X, since the Z is upcoming and the R9 295X2 is way better than anything nVidia has made (and easily $450 cheaper)

Thank you finally someone with some sense!

Two great cards. Make no mistake.

I bought a 295X2 a month ago and the performance / price point is absolutely astonishing. I'm absolutely aware that nVidia's Titan X is a faster 'single core' performer, but every AAA game that I've played so far has run like a banshee without any issues. The exception is Titanfall, but that game is so bad it's hardly an issue.

Battlefield 4 and Shadow of Mordore are just insane for example. The only thing that might usurp it is the forthcoming 390X, but I can't see it happening, hence I made the purchase!

jajajaj
donde estan los de Nvidia?
