GeForce GTX Titan vs Geforce GTX 690

Intro

The GeForce GTX Titan comes with core speeds of 837 MHz on the GPU, and 1502 MHz on the 6144 MB of GDDR5 RAM. It features 2688 SPUs along with 224 Texture Address Units and 48 ROPs.

Compare all that to the Geforce GTX 690, which makes use of a 28 nm design. nVidia has clocked the core speed at 915 MHz. The GDDR5 memory runs at a speed of 1502 MHz on this particular model. It features 1536 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX Titan 250 Watts
Geforce GTX 690 300 Watts
Difference: 50 Watts (20%)

Memory Bandwidth

The Geforce GTX 690 should in theory perform quite a bit faster than the GeForce GTX Titan in general. (explain)

Geforce GTX 690 384512 MB/sec
GeForce GTX Titan 288384 MB/sec
Difference: 96128 (33%)

Texel Rate

The Geforce GTX 690 should be a lot (more or less 25%) more effective at texture filtering than the GeForce GTX Titan. (explain)

Geforce GTX 690 234240 Mtexels/sec
GeForce GTX Titan 187488 Mtexels/sec
Difference: 46752 (25%)

Pixel Rate

The Geforce GTX 690 should be a lot (about 46%) faster with regards to full screen anti-aliasing than the GeForce GTX Titan, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Geforce GTX 690 58560 Mpixels/sec
GeForce GTX Titan 40176 Mpixels/sec
Difference: 18384 (46%)

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 maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of 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.

You can play crysis3 at very high graphics just using these gpus

With high fps u mean cause a GTX 680 run it with about 50-60...my old GTX could run it in high with 40FPS
Gamer87 says:
Yes i can play too at very high with 50 fps with a GTX680, just when you use too much filtering it goes to 40-45fps

its better 3x sli gtx 670 the same price $1000
Gary says:
Do you hav any spec's on the gtx690 4GB version against the Titan?
LEEROY says:
Gary - speed will be near identical with cards where the only difference is memory capacity. Bus speed and core clocks etc are all the same. Only difference is more frame buffer, so the GPU can set aside larger, more detailed frames during its workload.

A GTX 690 is a 4GB card; the 4GB comes from each gpu (@ 2GB Each).

Can i play Battlefield 4 on max with one 690?

Can I play Battlefield 4 on 4k? (i guess, never on max settings and 4k :O)

Anonymous says:
I dont see why the 690 couldnt run bf4 max at 4k how ever if you were Id suggest turn some of the post processing off.
