  • Access to DLSS 2 Super Resolution (2020).
  • 399900% more VRAM for high-resolution textures and newer games (8 GB vs 2 MB).

Trade-offs

  • 81.8% higher power demand at 200W vs 110W.
  • 24100% longer card at 242mm vs 1mm.

Mobility Radeon HD 3870 X2

2008

Why buy it

  • Draws 110W instead of 200W, a 90W reduction.
  • Measures 1mm instead of 242mm, a 241mm shorter card that is more SFF-friendly.

Trade-offs

  • Lower PassMark G3D performance (478 vs 20,312).
  • Less VRAM, with 2 MB vs 8 GB for high-resolution textures and newer games.
  • No DLSS support; it relies on FSR Upscaling / FSR 4 (2025) instead.
  • 2008 hardware with 2 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 12.5% HIGHER MSRP
