Geforce GTX 760 vs Geforce GTX 770

Intro

The Geforce GTX 760 has a core clock frequency of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1152 SPUs, 96 TAUs, and 32 Raster Operation Units.

Compare that to the Geforce GTX 770, which has a clock frequency of 1046 MHz and a GDDR5 memory frequency of 1753 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It is comprised of 1536 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 760 170 Watts
Geforce GTX 770 230 Watts
Difference: 60 Watts (35%)

Memory Bandwidth

The Geforce GTX 770 should theoretically be just a bit faster than the Geforce GTX 760 in general. (explain)

Geforce GTX 770 224384 MB/sec
Geforce GTX 760 192256 MB/sec
Difference: 32128 (17%)

Texel Rate

The Geforce GTX 770 is quite a bit (approximately 42%) more effective at AF than the Geforce GTX 760. (explain)

Geforce GTX 770 133888 Mtexels/sec
Geforce GTX 760 94080 Mtexels/sec
Difference: 39808 (42%)

Pixel Rate

If using a high resolution is important to you, then the Geforce GTX 770 is the winner, but it probably won't make a huge difference. (explain)

Geforce GTX 770 33472 Mpixels/sec
Geforce GTX 760 31360 Mpixels/sec
Difference: 2112 (7%)

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 max amount of data (in units of MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

thanks so much for this information.....

Wow, the GTX770 almost isn't worth the extra price.

Both my GTX760's is currently at 1,294mhz core and 1732mhz mem (6928mhz effective). Though my primay 760 will do 1840mhz (Elpida) (7360mhz effective).

770 has more cuda cores. Really the price to performance just isn't there, same with power. Kinda glad I didn't buy the 770.

The 760 vs 770 isn;'t really worth it, but the 770 vs 780, its bigger jump, so it looks a bit more appealing.

Not a big difference you say? almost double the fps on every game with my 770 compared to my 760. People may want to consider the 970s now but I still prefer a 780
