GeForce GTX Titan X vs Radeon R9 295X2

Intro

The GeForce GTX Titan X comes with a GPU core speed of 1000 MHz, and the 12288 MB of GDDR5 memory is set to run at 1750 MHz through a 384-bit bus. It also is comprised of 3072 Stream Processors, 192 Texture Address Units, and 96 Raster Operation Units.

Compare all of that to the Radeon R9 295X2, which comes with GPU clock speed of 1018 MHz, and 4096 MB of GDDR5 RAM set to run at 1250 MHz through a 512-bit bus. It also features 2816 Stream Processors, 176 TAUs, and 64 ROPs.

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

Texel Rate

The Radeon R9 295X2 should be quite a bit (approximately 87%) more effective at AF 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

If running with lots of anti-aliasing is important to you, then the Radeon R9 295X2 is superior to the GeForce GTX Titan X, and very much so. (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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of 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 also depends on quite a few other factors, especially 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?
