AMD Radeon HD 5870 Buyer's Guide
Positioning and generation
The Radeon HD 5870 is an AMD desktop graphics card built on the TeraScale 2 architecture, which makes it a very early generation. In our tier ranking it sits in the integrated and very old entry-level band, so it is no longer a mainstream choice for modern games.
Think of this card as something that can get older or lightweight games running rather than something that will run new releases smoothly. Its architecture and driver support are dated, and many current game features are simply not supported. It can still be useful for older or lighter titles, but it is not a sensible foundation for modern AAA games.
Key specs explained
The specifications we hold for this card are the AMD brand, the Radeon HD 5870 model name, the TeraScale 2 architecture, its desktop form factor, and 1GB of video memory. Clock speeds, shader counts, memory bus width and process node are not specified in our data, so we do not guess at them here.
For games, the 1GB of VRAM is the main limitation. Modern games often need several gigabytes of video memory for textures and scene data, so 1GB can become a bottleneck in newer titles. Even when the core has enough processing power, you may have to lower texture and detail settings to fit in memory. This architecture also lacks ray tracing and AI upscaling, so those features are not available as ways to improve image quality.
Suitable games and resolutions
Across 439 catalogue games with official requirements, our coverage figures reach 419 titles for this card. Of those, 262 fall below the official minimum, 88 meet the minimum but not the recommended level, 39 meet the recommended level, and 30 are well above recommended. In practical terms, most games sit below the official minimum, so you will be making compromises.
Examples that clear the recommended level include Peglin, Balatro, Brotato and Vampire Survivors, which are lightweight or pixel-style games. Titles that only reach the minimum include Hades II, Hollow Knight: Silksong and Scrap Mechanic. Heavier games such as Palworld and Microsoft Flight Simulator (2020) 40th Anniversary Edition fall below the minimum. For resolution, 1080p or lower is the sensible target at this level, with low to medium settings. Aiming higher is not realistic.
Compared with similar hardware
In our tier ranking the Radeon HD 5870 shares its band with the AMD Radeon HD 6950 and the AMD Radeon HD 7850, while the AMD Radeon Vega 8 Graphics is an integrated chip in the same tier. These four are the stronger end of this band, and their positions are close, so the real choice depends on your needs and used prices.
Below it, the NVIDIA GeForce GTX 650 Ti sits one tier lower, and the GTX 560 Ti and GTX 470 sit roughly two tiers lower. This only describes relative position in our requirement ranking, not measured game performance.
Buying new or used
This card is very old, so you will almost certainly be buying it used. Check that your power supply has enough wattage and the right PCIe power connectors, and confirm your case can fit the card's length and cooler thickness.
For used cards, be wary of units that were used for mining or run under long heavy loads. Fans, thermal paste and capacitors may be worn out, so check that the fan spins properly and look for burn marks or a burnt smell. A seller who offers a warranty or a return option gives you more protection. Because this generation was discontinued years ago, new-product warranty and official support are very limited, so factor that in.
Upgrade advice
If you are coming from an even older card, or you only want a few lightweight games to run, this card may be a reasonable improvement. If your target is newer games, moving up to a higher tier makes more sense. Options above it include the AMD Radeon HD 6950 and the AMD Radeon HD 7850, which generally offer better video memory and architecture support.
Whichever card you choose, balance it with your CPU and RAM. A good graphics card will not help much if the processor is dated or you only have 4GB of memory. When replacing the GPU, also check whether the CPU and RAM need upgrading, and make sure your power supply has headroom.
