Quadro K620M

2015

Why buy it

✅300% more VRAM for high-resolution textures and newer games (4 GB vs 1 GB).
✅Draws 30W instead of 86W, a 56W reduction.
✅More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Trade-offs

❌Very weak future-proofing: 2015-era hardware with 4 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌Lower G3D Mark per dollar, at 0 vs 9.0 G3D/$ (Unknown MSRP vs $130 MSRP).

Radeon HD 5750

2009

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 9.0 vs 0 G3D/$ ($130 MSRP vs Unknown MSRP).

Trade-offs

❌Less VRAM, with 1 GB vs 4 GB for high-resolution textures and newer games.
❌Very weak future-proofing: 2009-era hardware with 1 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌186.7% higher power demand at 86W vs 30W.

Quick Answers

So, is Radeon HD 5750 better than Quadro K620M?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 1,159 vs 1,169 in G3D Mark. The bigger reason to prefer Radeon HD 5750 is the overall package: you are getting FSR upscaling.

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

Quadro K620M is the more future-proof choice for 2026 and beyond. You are getting a newer 2015 generation instead of 2009, more VRAM at 4 GB instead of 1 GB, the stronger feature stack with no meaningful modern upscaling stack instead of FSR upscaling, and a 28nm process instead of 40nm. 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?

Radeon HD 5750 can still make sense if you find it at the right price, especially around $130 MSRP. Radeon HD 5750 is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon HD 5750 is priced in an unclear MSRP range at $130 MSRP versus an unclear MSRP, and you are getting 0.9% higher G3D Mark. Quadro K620M is the newer 2015 card, so it still has a real case if you care more about newer architecture, lower power draw (30W vs 86W), and future-proofing than about squeezing out the strongest gaming value today.

When does Quadro K620M make more sense than Radeon HD 5750?

Yes. Quadro K620M is still an excellent gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It makes more sense if your priority is newer architecture, lower power draw (30W vs 86W), future-proofing, and staying closer to an unclear MSRP more than squeezing out the extra headroom of Radeon HD 5750. The trade-off is that Radeon HD 5750 currently gives you 0.9% higher G3D Mark. It also leads G3D-per-dollar by 100+%.
