About G3D Mark

G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

Radeon Pro Vega 20 vs Tesla K8: Pros, Cons & Final Verdict

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

Radeon Pro Vega 20

2018

Why buy it

  • More future proof: GCN 5.0 (2017−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

  • Less VRAM, with Unknown vs 4 GB for high-resolution textures and newer games.
  • 2018 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • Lower G3D Mark per dollar, at 0 vs 5.1 G3D/$ (Unknown MSRP vs $1,000 MSRP).

Tesla K8

2014

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 5.1 vs 0 G3D/$ ($1,000 MSRP vs Unknown MSRP).
  • 100+% more VRAM for high-resolution textures and newer games (4 GB vs Unknown).
  • Radeon Pro Vega 20 is already obsolete for modern gaming, so Tesla K8 is the less risky modern option long term.

Trade-offs

  • 2014 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
