Compare any two graphics cards:
Radeon HD 6950 2GB vs Radeon HD 7870
IntroThe Radeon HD 6950 2GB comes with core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 memory. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.Compare that to the Radeon HD 7870, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM is set to run at a frequency of 1200 MHz on this specific card. It features 1280 SPUs as well as 80 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6950 2GB should in theory perform just a bit faster than the Radeon HD 7870 in general. (explain)
Texel RateThe Radeon HD 7870 should be a little bit (more or less 14%) more effective at AF than the Radeon HD 6950 2GB. (explain)
Pixel RateThe Radeon HD 7870 will be much (more or less 25%) more effective at FSAA than the Radeon HD 6950 2GB, and will be able to handle higher resolutions while still performing well. (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 maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

One Response to “Radeon HD 6950 2GB vs Radeon HD 7870”With the 7870s OC abilities it does surpass the 6950 by large margins, granted it has less TPU and SPUs but it can clock to 1250 mhz mem and 1200+ Core Clocks. I got a 7870 as an upgrade to my 6950, and I'm happy :3
