Quadro M3000M

2015

Why buy it

✅33.3% more VRAM for high-resolution textures and newer games (4 GB vs 3 GB).
✅Draws 75W instead of 375W, a 300W reduction.
✅More future proof: Maxwell 2.0 (2014−2019) on 28nm with a newer platform for upcoming games.

Trade-offs

❌Lower average FPS than Radeon HD 7990 across 50 tracked games in our benchmark data.
❌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 5.6 G3D/$ (Unknown MSRP vs $999 MSRP).

Radeon HD 7990

2013

Why buy it

✅16.1% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 5.6 vs 0 G3D/$ ($999 MSRP vs Unknown MSRP).

Trade-offs

❌Less VRAM, with 3 GB vs 4 GB for high-resolution textures and newer games.
❌Very weak future-proofing: 2013-era hardware with 3 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌400% higher power demand at 375W vs 75W.

Quick Answers

So, is Quadro M3000M better than Radeon HD 7990?

Yes. Quadro M3000M is the better GPU overall here. You are getting 0.1% higher PassMark G3D performance and 4 GB vs 3 GB of VRAM. It also comes from 2015 instead of 2013, which helps its case as the more complete modern gaming card.

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

Quadro M3000M is the more future-proof choice for 2026 and beyond. You are getting a newer 2015 generation instead of 2013, more VRAM at 4 GB instead of 3 GB, and the stronger feature stack with no meaningful modern upscaling stack instead of FSR upscaling. 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?

Quadro M3000M is the smarter buy by a wide margin. Quadro M3000M is priced in an unclear MSRP range at an unclear MSRP versus $999 MSRP, and you are getting lower estimated average FPS across 50 tracked games in our benchmark data and 0.1% higher G3D Mark. Radeon HD 7990 really only makes sense now as a very cheap stopgap or a used-market placeholder.

Is Radeon HD 7990 still worth buying for gaming in 2026?

No, not for a fresh gaming build. Radeon HD 7990 is 2013 hardware with 3 GB of VRAM, 5,566 in G3D Mark, and FSR upscaling. That is simply too far behind to be an easy modern recommendation.
