Geforce GTX 670 vs Geforce GTX 770

Intro

The Geforce GTX 670 comes with a core clock frequency of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1344 SPUs, 112 TAUs, and 32 Raster Operation Units.

Compare those specifications to the Geforce GTX 770, which has core speeds of 1046 MHz on the GPU, and 1753 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs as well as 128 Texture Address Units and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.

Not worth upgrading it

TheMutt06 says:

Upgrading from GTX 670 4GIG SC+ SLI to GTX 770 4GIG SLI NOT worth it for the insignificant performance improvement...if any.

Captain says:

definetly not worth upgrading 🙂

eaglespeed says:

same here 4gb sli gtx 670 asus, only 15% performance deference or 8fps is not worth it at all, games which run smooth already won`t run smoother and games who are sluggish in 30fps wont get any better so whats the point of upgrading

grue says:

can i bollwo your groue

Nigga says:

Nigga nigga nigga, you're 100% nigga

Matt says:

I'm looking at both, upgrading from a 550ti. I guess i go for the 770?
