Compare any two graphics cards:
Radeon HD 6950 2GB vs Radeon HD 7870
IntroThe Radeon HD 6950 2GB has a GPU clock speed of 800 MHz, and the 2048 MB of GDDR5 RAM runs at 1250 MHz through a 256-bit bus. It also is made up of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.Compare all that to the Radeon HD 7870, which features a core clock frequency of 1000 MHz and a GDDR5 memory frequency of 1200 MHz. It also features a 256-bit bus, and uses a 28 nm design. It features 1280 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6950 2GB should theoretically be a little bit better than the Radeon HD 7870 overall. (explain)
Texel RateThe Radeon HD 7870 should be a little bit (more or less 14%) more effective at anisotropic filtering than the Radeon HD 6950 2GB. (explain)
Pixel RateThe Radeon HD 7870 will be much (approximately 25%) better at FSAA than the Radeon HD 6950 2GB, and will be capable of handling 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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum 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
