HD 7950 vs HD 7870 XT
Comparison of graphics card architecture, market segment, value for money and other general parameters.
General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.
Compatibility, dimensions and requirements
Information on compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility).
Parameters of memory installed: its type, size, bus, clock and resulting bandwidth. Note that GPUs integrated into processors have no dedicated VRAM and use a shared part of system RAM.
Video outputs and ports
Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.
Supported technological solutions. This information will prove useful if you need some particular technology for your purposes.
APIs supported, including particular versions of those APIs.
Non-gaming benchmark performance comparison. Note that overall benchmark performance is measured in points in 0-100 range.
This is our combined benchmark performance rating. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.
3DMark Fire Strike Graphics
Fire Strike is a DirectX 11 benchmark for gaming PCs. It features two separate tests displaying a fight between a humanoid and a fiery creature seemingly made of lava. Using 1920x1080 resolution, Fire Strike shows off some realistic enough graphics and is quite taxing on hardware.
This is probably the most ubiquitous benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.
Rendering quality tests
Cryptocurrency mining performance of Radeon HD 7950 and Radeon HD 7870 XT. Usually measured in megahashes per second.
Let's see how good the compared graphics cards are for gaming. Particular gaming benchmark results are measured in FPS.
HD 7950 satisfies 93% minimum and 79% recommended requirements of all games known to us.
HD 7870 XT satisfies 92% minimum and 78% recommended requirements of all games known to us.

Competitors of Radeon HD 7870 XT from NVIDIA
We believe that the nearest equivalent to Radeon HD 7870 XT from NVIDIA is GeForce GTX 580, which is nearly equal in speed and higher by 1 position in our rating.
Here are some closest NVIDIA rivals to Radeon HD 7870 XT:
Advantages of AMD Radeon HD 7950
6.6% better performance in benchmarks
Wider memory bus (384 vs 256 bit)
More pipelines (1792 vs 1536)
Higher memory bandwidth (240 vs 192 GB/s)
Advantages of AMD Radeon HD 7870 XT
Somewhat newer (19 November 2012 vs 31 January 2012)
Cheaper ($133 vs $396)
Lower power consumption (185W vs 300W), meaning that the rival with higher TDP might require a better cooler or other thermal solution.
So, which one is the better GPU?
Technical City couldn't decide between AMD Radeon HD 7950 and AMD Radeon HD 7870 XT. The differences in performance seem too small.
