FirePro D300 vs Radeon Pro 5300M: Pros, Cons & Final Verdict

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

FirePro D300

2014

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 11.4 vs 0 G3D/$ ($500 MSRP vs Unknown MSRP).

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.
❌76.5% higher power demand at 150W vs 85W.

Radeon Pro 5300M

2019

Why buy it

✅FirePro D300 is already obsolete for modern gaming, so Radeon Pro 5300M is the less risky modern option long term.
✅Draws 85W instead of 150W, a 65W reduction.
✅More future proof: RDNA 1.0 (2019−2020) on 7nm 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.
❌Lower G3D Mark per dollar, at 0 vs 11.4 G3D/$ (Unknown MSRP vs $500 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

Radeon Pro 5300M is the faster gaming card right now based on the synthetic data we have. It leads by 2.3% in PassMark G3D (5,853 vs 5,722), which is the best performance signal available in this matchup.

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

Radeon Pro 5300M is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 7nm process instead of 28nm, and a newer 2019 generation instead of 2014. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

FirePro D300 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, FirePro D300 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon Pro 5300M has the stronger long-term case.
