ATI Radeon HD 3870: specs and benchmarks
ATI started Radeon HD 3870 sales 19 November 2007 at a recommended price of $269. This is TeraScale architecture desktop card based on 55 nm manufacturing process and primarily aimed at office use. 512 MB of GDDR4 memory clocked at 2.25 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 72.06 GB/s.
Compatibility-wise, this is dual-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 241 mm. 1x 6-pin power connector is required, and power consumption is at 106 Watt.
It provides poor gaming and benchmark performance at 2.13 percent of a leader's which is AMD Radeon RX 6900 XT.
Of Radeon HD 3870's architecture, market segment and release date.
Radeon HD 3870's general performance parameters such as number of shaders, GPU base clock, manufacturing process, texturing and calculation speed. These parameters indirectly speak of Radeon HD 3870's performance, but for precise assessment you have to consider its benchmark and gaming test results.
Compatibility, dimensions and requirements
Information on Radeon HD 3870's 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 on Radeon HD 3870: 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 3870. 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.
APIs supported by Radeon HD 3870, sometimes including their particular versions.
Non-gaming benchmark performance of Radeon HD 3870. 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.
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.
Let's see how good Radeon HD 3870 is for gaming. Particular gaming benchmark results are measured in frames per second. Comparisons with game system requirements are included, but remember that sometimes official requirements may reflect reality inaccurately.
This video card matches 68% minimum and 59% recommended requirements of all games known to us.
Overall Radeon HD 3870 performance compared to nearest competitors among desktop video cards.
We believe that the nearest equivalent to Radeon HD 3870 from NVIDIA is GeForce 820A, which is slower by 1% and lower by 1 position in our rating.
