FirePro D500

2014

Why buy it

✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).
✅More future proof: GCN 1.0 (2012−2020) on 28nm with a newer platform for upcoming games.

Trade-offs

❌Very weak future-proofing: 2014-era hardware with 4 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌
233.3% HIGHER MSRP
$500 MSRPvs$150 MSRP
❌Lower G3D Mark per dollar, at 4.5 vs 14.8 G3D/$ ($500 MSRP vs $150 MSRP).
❌508.9% higher power demand at 274W vs 45W.

Quadro K620

2014

Why buy it

✅Costs $350 less on MSRP ($150 MSRP vs $500 MSRP).
✅Delivers 224.7% more G3D Mark for each dollar spent, at 14.8 vs 4.5 G3D/$ ($150 MSRP vs $500 MSRP).
✅Draws 45W instead of 274W, a 229W reduction.

Trade-offs

Quick Answers

So, is FirePro D500 better than Quadro K620?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 2,272 vs 2,213 in G3D Mark. The bigger reason to prefer FirePro D500 is the overall package: you are getting no meaningful modern upscaling stack.

Which one is more future-proof for 2026 and beyond?

FirePro D500 is the more future-proof choice for 2026 and beyond. You are getting more VRAM at 4 GB instead of 2 GB. That extra memory headroom makes it the safer pick for newer games, heavier textures, and higher settings over time.

Which one is the smarter buy today, not just the cheaper card?

FirePro D500 is the smarter buy by a wide margin. FirePro D500 is about 233.3% more expensive on MSRP at $500 MSRP versus $150 MSRP, and you are getting 2.7% higher G3D Mark. Quadro K620 really only makes sense now as a very cheap stopgap or a used-market placeholder.

Is Quadro K620 still worth buying for gaming in 2026?

No, not for a fresh gaming build. Quadro K620 is 2014 hardware with 2 GB of VRAM, 2,213 in G3D Mark, and no meaningful modern upscaling stack. That is simply too far behind to be an easy modern recommendation.
