See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

FireStream 9270

2008

Why buy it

  • 100% more VRAM for high-resolution textures and newer games (2 GB vs 1 GB).
  • Draws 160W instead of 286W, a 126W reduction.
  • Measures 241mm instead of 267mm, a 26mm shorter card that is more SFF-friendly.

Trade-offs

  • 2008 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 172.5% HIGHER MSRP
    $1,499 MSRPvs$550 MSRP
  • Lower G3D Mark per dollar, at 0.9 vs 2.4 G3D/$ ($1,499 MSRP vs $550 MSRP).
