Compare any two graphics cards:
Radeon HD 6850 vs Radeon HD 7870
IntroThe Radeon HD 6850 uses a 40 nm design. AMD has clocked the core frequency at 775 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific card. It features 960 SPUs as well as 48 Texture Address Units and 32 Rasterization Operator Units.Compare those specifications to the Radeon HD 7870, which features GPU clock speed of 1000 MHz, and 2048 MB of GDDR5 RAM set to run at 1200 MHz through a 256-bit bus. It also features 1280 Stream Processors, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7870 should be a little bit faster than the Radeon HD 6850 overall. (explain)
Texel RateThe Radeon HD 7870 should be quite a bit (approximately 115%) faster with regards to AF than the Radeon HD 6850. (explain)
Pixel RateThe Radeon HD 7870 will be a lot (about 29%) better at full screen anti-aliasing than the Radeon HD 6850, 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 largest amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per 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 - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.

One Response to “Radeon HD 6850 vs Radeon HD 7870”I'm thinking about changing the 6850 to 7870 for BF4.
Is it worth it?
What about the different PCI-E slots, this 7870 needs 3.0?
Currently I have
AsRock G31 M-S mobo
Q9550 @ 2.83
Radeon HD6850 1GB
4GB RAM DDR2
1366x768 res
It's shocking in some maps in BF4 wether it's on High or Low quality, with AA off ofcourse.
Changing to 2x 4GB Ram is not an option since they are amazingly expensive (DDR2).
