Quadro CX vs Radeon 620: Pros, Cons & Final Verdict

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

Quadro CX

2008

Why buy it

✅42.8% more average FPS across 50 tracked games in our benchmark data.
✅700% more VRAM for high-resolution textures and newer games (4 GB vs 512 MB).

Trade-offs

❌2008 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
1899% HIGHER MSRP
$1,999 MSRPvs$100 MSRP
❌Lower G3D Mark per dollar, at 0.5 vs 9.5 G3D/$ ($1,999 MSRP vs $100 MSRP).
❌200% higher power demand at 150W vs 50W.

Radeon 620

2019

Why buy it

✅Costs $1,899 less on MSRP ($100 MSRP vs $1,999 MSRP).
✅Delivers 1913.8% more G3D Mark for each dollar spent, at 9.5 vs 0.5 G3D/$ ($100 MSRP vs $1,999 MSRP).
✅Quadro CX is already obsolete for modern gaming, so Radeon 620 is the less risky modern option long term.
✅Draws 50W instead of 150W, a 100W reduction.

Trade-offs

❌Lower average FPS than Quadro CX across 50 tracked games in our benchmark data.
❌Less VRAM, with 512 MB vs 4 GB for high-resolution textures and newer games.
❌2019 hardware with 512 MB of VRAM already sits in legacy territory for modern games.

Quick Answers

Which GPU is faster for gaming right now?

Quadro CX is the faster gaming card right now. In our data, it leads by 42.8% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon 620 instead at 954 vs 947, so for this question the real-game FPS result matters more than the synthetic split.

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

Radeon 620 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 28nm process instead of 55nm, and a newer 2019 generation instead of 2008. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon 620 makes the most sense to buy today. It is $1,899 cheaper on MSRP at $100 vs $1,999, and it leads G3D-per-dollar by 1913.8% (9.5 vs 0.5), which is enough to swing the recommendation its way. Quadro CX still makes more sense if max raw gaming performance matters more than value.
