MSI Radeon RX 580 ARMOR 8G OC

The MSI Radeon RX 580 ARMOR 8G OC is a graphics card built on the AMD Radeon RX 500 Series architecture. It connects via a PCI Express 3.0 x16 interface and features 8GB of GDDR5 memory across a 256-Bit bus. The card delivers a boost clock of 1366 MHz and 2304 stream processors for 1080p gaming workloads.

Suits 1080p gamers on PCIe 3.0 systems

This card suits builders running a PCI Express 3.0 platform who want 8GB VRAM for 1080p gaming across up to five monitors. It provides HDMI, DisplayPort and DVI outputs for mixed display setups. Buyers needing PCIe 4.0 bandwidth, newer encoding features or ray-tracing hardware should consider a different GPU.

8GB GDDR5 on a 256-Bit memory interface

The 8GB GDDR5 frame buffer on a 256-Bit interface is the specification that decides fit. It determines texture capacity and memory bandwidth for modern titles at 1080p resolution. If a build requires more VRAM or a wider bus for higher resolutions, this model will not match the requirement.

Questions about this item

Will the PCI Express 3.0 x16 interface work with my older PCIe 2.0 motherboard slot?

The card uses a PCI Express 3.0 x16 interface which is backward compatible with PCIe 2.0 slots, though bandwidth will be limited to the older standard's speed.

How can I verify the boost clock of 1366 MHz is active under load?

Use GPU monitoring software to observe the core frequency while running a 3D workload; it should reach 1366 MHz when the Radeon RX 580 GPU hits its boost state.

Does the box include cables for the two HDMI, two DisplayPort and one DVI outputs?

The card provides two HDMI, two DisplayPort and one DVI port; monitor cables are not included and must be purchased separately to match your displays.
