AMD Radeon HD 8670M: specs and benchmarks

Summary
AMD started Radeon HD 8670M sales 16 November 2012. This is GCN architecture notebook card based on 28 nm manufacturing process and primarily aimed at office use. 1 GB of DDR3 memory clocked at 2 GHz are supplied, and together with 64 Bit memory interface this creates a bandwidth of 16 GB/s.
Compatibility-wise, this is card attached via PCIe 3.0 x8 interface.
It provides poor gaming and benchmark performance at 0.51 percent of a leader's which is AMD Radeon RX 6900 XT.
General info
Of Radeon HD 8670M's architecture, market type and release date.
Technical specs
Radeon HD 8670M's general performance parameters such as number of shaders, GPU core clock, manufacturing process, texturing and calculation speed. These parameters indirectly speak of Radeon HD 8670M's performance, but for precise assessment you have to consider its benchmark and gaming test results.
Compatibility, dimensions and requirements
Information on Radeon HD 8670M's compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.
Memory
Parameters of memory installed on Radeon HD 8670M: its type, size, bus, clock and resulting bandwidth. Note that GPUs integrated into processors don't have dedicated memory and use a shared part of system RAM.
Video outputs and ports
Types and number of video connectors present on Radeon HD 8670M. As a rule, this section is relevant only for desktop reference video cards, since for notebook ones the availability of certain video outputs depends on the laptop model.
API support
APIs supported by Radeon HD 8670M, sometimes including their particular versions.
Benchmark performance
Non-gaming benchmark performance of Radeon HD 8670M. Note that overall benchmark performance is measured in points in 0-100 range.
Overall score
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 Cloud Gate GPU
Cloud Gate is an outdated DirectX 11 feature level 10 benchmark that was used for home PCs and basic notebooks. It displays a few scenes of some weird space teleportation device launching spaceships into unknown, using fixed resolution of 1280x720. Just like Ice Storm benchmark, it has been discontinued in January 2020 and replaced by 3DMark Night Raid.
3DMark Fire Strike Score
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.
3DMark 11 Performance GPU
3DMark 11 is an obsolete DirectX 11 benchmark by Futuremark. It used four tests based on two scenes, one being few submarines exploring the submerged wreck of a sunken ship, the other is an abandoned temple deep in the jungle. All the tests are heavy with volumetric lighting and tessellation, and despite being done in 1280x720 resolution, are relatively taxing. Discontinued in January 2020, 3DMark 11 is now superseded by Time Spy.
3DMark Vantage Performance
3DMark Vantage is an outdated DirectX 10 benchmark using 1280x1024 screen resolution. It taxes the graphics card with two scenes, one depicting a girl escaping some militarized base located within a sea cave, the other displaying a space fleet attack on a defenseless planet. It was discontinued in April 2017, and Time Spy benchmark is now recommended to be used instead.
Unigine Heaven 3.0
This is an old DirectX 11 benchmark using Unigine, a 3D game engine by eponymous Russian company. It displays a fantasy medieval town sprawling over several flying islands. Version 3.0 was released in 2012, and in 2013 it was superseded by Heaven 4.0, which introduced several slight improvements, including a newer version of Unigine.
Passmark
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.
Mining hashrates
Cryptocurrency mining performance of Radeon HD 8670M. Usually measured in megahashes per second.
Game benchmarks
Let's see how good Radeon HD 8670M is for gaming. Particular gaming benchmark results are measured in FPS. Comparisons with system requirements are included, but remember that sometimes official requirements may reflect real performance inaccurately.
Relative perfomance
Overall Radeon HD 8670M performance compared to nearest competitors among notebook video cards.
NVIDIA equivalent
We believe that the nearest equivalent to Radeon HD 8670M from NVIDIA is GeForce 820M, which is nearly equal in speed and lower by 3 positions in our rating.
