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 clocked the core speed at 980 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this particular model. It features 960 SPUs along with 80 TAUs and 24 Rasterization Operator Units.Compare all of that to the Radeon HD 7850, which features GPU core 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 BandwidthAs far as performance goes, the Radeon HD 7850 should in theory be just a bit superior to the GeForce GTX 660 in general. (explain)
Texel RateThe GeForce GTX 660 is quite a bit (more or less 42%) more effective at anisotropic filtering than the Radeon HD 7850. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 7850 is superior to the GeForce GTX 660, though only just barely. (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 max amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it 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, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number 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 applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on 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 max 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?
