Entry-level Radeon GPU

The Sapphire Tech Radeon B403 is a basic graphics card built around the ATI Radeon HD 3470 chipset. It carries 256MB of DDR3 video memory and targets simple desktop display tasks or legacy system maintenance.

PCI-Express interface limits

The card connects through a standard PCI-Express slot and provides 2x Display Port outputs for monitor attachment. Bandwidth and feature support are constrained by the capabilities of the HD 3470 GPU and the DDR3 memory subsystem.

Compatibility checks

Verify that the motherboard has a free PCI-Express slot and that the chassis offers enough length clearance for a full-height bracket. Confirm the power supply can deliver any auxiliary power the board requires and that the operating system includes a driver for the HD 3470.

Questions about this item

Is the 256MB Radeon B403 suitable for a multi-display office setup?

The card provides 256MB of DDR3 memory and two DisplayPort outputs, so it can drive two monitors for typical productivity tasks.

What does the 256MB DDR3 frame buffer mean for everyday desktop use?

The 256MB DDR3 frame buffer is enough for standard office applications, video playback and dual-monitor operation, but it is not intended for 3D workloads.

Does the PCI-E interface on the B403 limit the memory bandwidth?

The PCI-E connection feeds the Radeon HD 3470 GPU and its 256MB DDR3 memory; bandwidth is defined by that memory subsystem rather than the slot itself.
