ATI Mobility Radeon HD 4850: specs and benchmarks
ATI started Mobility Radeon HD 4850 sales 9 January 2009. This is Terascale 1 architecture notebook card based on 55 nm manufacturing process and primarily aimed at office use. 1 GB of GDDR3 memory clocked at 850 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 54.4 GB/s.
Compatibility-wise, this is card attached via PCIe 2.0 x16 interface.
It provides poor gaming and benchmark performance at 1.91 percent of a leader's which is AMD Radeon RX 6900 XT.
Of Mobility Radeon HD 4850's architecture, market type and release date.
Mobility Radeon HD 4850's general performance parameters such as number of shaders, GPU core clock, manufacturing process, texturing and calculation speed. These parameters indirectly speak of Mobility Radeon HD 4850's performance, but for precise assessment you have to consider its benchmark and gaming test results.
Compatibility, dimensions and requirements
Information on Mobility Radeon HD 4850'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.
Parameters of memory installed on Mobility Radeon HD 4850: 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 Mobility Radeon HD 4850. 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 Mobility Radeon HD 4850, sometimes including their particular versions.
Non-gaming benchmark performance of Mobility Radeon HD 4850. Note that overall benchmark performance is measured in points in 0-100 range.

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3DMark Vantage is an outdated DirectX 10 benchmark using 1280x1024 screen resolution.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.
Let's see how good Mobility Radeon HD 4850 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.
