GeForce GTX 650 Ti vs Radeon HD 6870
Intro
The GeForce GTX 650 Ti uses a 28 nm design. nVidia has set the core frequency at 928 MHz. The GDDR5 RAM is set to run at a frequency of 1350 MHz on this model. It features 768 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.Compare all that to the Radeon HD 6870, which comes with a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It features 1120 SPUs, 56 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.

2 Responses to “GeForce GTX 650 Ti vs Radeon HD 6870”I wonder how Nvidia can take a 128 Bit Mem bus card, And then make it completely outclass other AMD cards with a 256 bit bus? I thought their 128 Bit bus cards were junk I even used to laugh at them, Then my ATI 5870 fried, And I then bought a GTX-650_Ti on sale for $90 bucks, And was completly shocked by its performance. It completely outperforms my old ATI 5870 in all my games old and new, I can never go back to AMD now. (unless of'course I get a good deal) I never pass up a good deal.
I just bought a gtx 650 ti 2gb edition, I'm liking it much better than my HD 7770 so far. I wanted to go smaller, silent and less power consumption. That's exactly what I got out of the gtx 650 nicely done Nvidia. Keep this track record and you might even get me to stop using ATI period.
