Compare any two graphics cards:
GeForce GTX 660 vs Radeon HD 7850
IntroThe GeForce GTX 660 comes with a GPU clock speed of 980 MHz, and the 2048 MB of GDDR5 RAM runs at 1502 MHz through a 192-bit bus. It also is made up of 960 SPUs, 80 TAUs, and 24 Raster Operation Units.Compare those specifications to the Radeon HD 7850, which features a GPU core clock speed of 860 MHz, and 2048 MB of GDDR5 RAM set to run at 1200 MHz through a 256-bit bus. It also is comprised of 1024 SPUs, 64 TAUs, and 32 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7850 should theoretically be just a bit faster than the GeForce GTX 660 overall. (explain)
Texel RateThe GeForce GTX 660 is quite a bit (about 42%) better at anisotropic filtering than the Radeon HD 7850. (explain)
Pixel RateThe Radeon HD 7850 should be just a bit (about 17%) better at AA than the GeForce GTX 660, and will be capable of handling higher screen resolutions better. (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: Bandwidth is the max amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach 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?
