Compare any two graphics cards:
GeForce GTX 660 vs Radeon HD 7850
IntroThe GeForce GTX 660 makes use of a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 RAM is set to run at a speed of 1502 MHz on this specific model. It features 960 SPUs along with 80 Texture Address Units and 24 ROPs.Compare those specifications to the Radeon HD 7850, which comes with a core clock frequency of 860 MHz and a GDDR5 memory frequency of 1200 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is made up of 1024 SPUs, 64 TAUs, and 32 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 7850 should be 7% quicker than the GeForce GTX 660 in general, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 660 is a lot (more or less 42%) more effective at texture filtering than the Radeon HD 7850. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 7850 is the winner, but only just. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better 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 most pixels that the graphics chip could possibly record to its local memory per 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 - sometimes also referred to as 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 - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.

16 Responses to “GeForce GTX 660 vs Radeon HD 7850”i have sapphire 7850 2gb oc but gtx 660 better
evga gtx660 is alot better than 7850.Gtx660 beat 7850 easily
I bought the GTX 660 for 1366x768, and easily touched 60fps at all games
Can anyone ans is texal rate so important?
I have a 7850 OC. That's dumb. 660 is much and much better! Even for linux.
660 or 7850 oc...
is amd better on 1680 X 1080
as an engineer i'd say all those tests are more or less biased.
from a sticktly technical point of view hd7850 should be a much more powerful card
it's not only about the gpu /memory clocks
hd 7850 is much more customizable and OC-efficient.
I have the 660 and my friend has the 7850, when we compared frames on games such as bf3 and wow (using same processor) the 660 came out on top by about 5 fps
I think the saddest part about this benchmark is, AMD's 7850 is $100 cheaper.
gtx 660 is in stock better than the 7850 in stock clock, but when it comes to overclocking, the 7850 has a little advantage overall. Still nvidia has physx built in 🙂
me cago en tus muertos
i won the gtx 660 evga for the win signature 2 edition and its blazing fast.
Hi,im thinking on buying one of the two.And i just want to know which is better the gtx 660 or the 7850?
Which is better if I have AMD A10-5800k APU?
