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

GeForce 8400

2014

Why buy it

✅Costs $1,066 less on MSRP ($45 MSRP vs $1,111 MSRP).
✅Draws 33W instead of 140W, a 107W reduction.
✅Measures 170mm instead of 241mm, a 71mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower average FPS than RTX A4000 across 50 tracked games in our benchmark data.
❌Less VRAM, with 512 MB vs 16 GB for high-resolution textures and newer games.
❌2014 hardware with 512 MB 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 1.8 vs 17.5 G3D/$ ($45 MSRP vs $1,111 MSRP).

RTX A4000

2021

Why buy it

✅8816.3% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 873.2% more G3D Mark for each dollar spent, at 17.5 vs 1.8 G3D/$ ($1,111 MSRP vs $45 MSRP).
✅3100% more VRAM for high-resolution textures and newer games (16 GB vs 512 MB).
✅Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.

Trade-offs

❌324.2% higher power demand at 140W vs 33W.
❌41.8% longer card at 241mm vs 170mm.

Quick Answers

Which GPU is faster for gaming right now?

RTX A4000 is the faster gaming card right now. In our data, it leads by 8816.3% in average FPS across 50 tracked games in our benchmark data and by 23928.4% in PassMark G3D (19,463 vs 81), so the answer here is pretty clean.

Which GPU is the safer long-term pick for 2026 and beyond?

RTX A4000 is the safer long-term pick for 2026 and beyond. The case is simple: 16 GB vs 512 MB of VRAM, a 8nm process instead of 28nm, 48 vs 0 ray-tracing units, and a newer 2021 generation instead of 2014. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

RTX A4000 makes the most sense to buy today. It is $1,066 more expensive on MSRP at $1,111 vs $45, and it leads G3D-per-dollar by 873.2% (17.5 vs 1.8), so the value case lines up with the gaming result.
