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

Radeon RX 540

2017

Why buy it

✅Costs $60 less on MSRP ($99 MSRP vs $159 MSRP).
✅Delivers 57.8% more G3D Mark for each dollar spent, at 21.6 vs 13.7 G3D/$ ($99 MSRP vs $159 MSRP).

Trade-offs

❌Lower average FPS than Radeon RX 640 across 50 tracked games in our benchmark data.
❌2017 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon RX 640

2019

Why buy it

✅15.1% more average FPS across 50 tracked games in our benchmark data.
✅Radeon RX 540 is already obsolete for modern gaming, so Radeon RX 640 is the less risky modern option long term.
✅More future proof: GCN 4.0 (2016−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

❌Older hardware, 4 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌
60.6% HIGHER MSRP
$159 MSRPvs$99 MSRP
❌Lower G3D Mark per dollar, at 13.7 vs 21.6 G3D/$ ($159 MSRP vs $99 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

Radeon RX 640 is the faster gaming card right now. In our data, it leads by 15.1% in average FPS across 50 tracked games in our benchmark data and by 1.8% in PassMark G3D (2,172 vs 2,134), so the answer here is pretty clean.

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

Radeon RX 640 is the safer long-term pick for 2026 and beyond. The case is simple: the newer frame-generation stack, FSR Frame Generation + AFMF (2023) instead of FSR Frame Generation (2023) and a newer 2019 generation instead of 2017. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon RX 540 makes the most sense to buy today. It is $60 cheaper on MSRP at $99 vs $159, and it leads G3D-per-dollar by 57.8% (21.6 vs 13.7), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, Radeon RX 540 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon RX 640 has the stronger long-term case.
