GeForce RTX 3070

2020

Why buy it

✅+1499.7% higher PassMark G3D performance.
✅Delivers 858.5% more G3D Mark for each dollar spent, at 44.4 vs 4.6 G3D/$ ($499 MSRP vs $299 MSRP).
✅Access to DLSS 2 Super Resolution (2020).
✅300% more VRAM for high-resolution textures and newer games (8 GB vs 2 GB).
✅More future proof: Ampere (2020−2025) on 8nm with a newer platform for upcoming games.

Trade-offs

❌46.7% higher power demand at 220W vs 150W.

Radeon HD 4870

2008

Why buy it

✅Costs $200 less on MSRP ($299 MSRP vs $499 MSRP).
✅Draws 150W instead of 220W, a 70W reduction.

Trade-offs

❌Lower PassMark G3D performance (1,386 vs 22,172).
❌Less VRAM, with 2 GB vs 8 GB for high-resolution textures and newer games.
❌No DLSS support; it relies on FSR Upscaling / FSR 4 (2025) instead.
❌Very weak future-proofing: 2008-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌Lower G3D Mark per dollar, at 4.6 vs 44.4 G3D/$ ($299 MSRP vs $499 MSRP).

Quick Answers

So, is GeForce RTX 3070 better than Radeon HD 4870?

Yes. GeForce RTX 3070 is clearly the better overall GPU here. You are also looking at 22,172 vs 1,386 in G3D Mark. On top of that, GeForce RTX 3070 is a 2020 card with DLSS Super Resolution, while Radeon HD 4870 is a 2008 model from an older generation with FSR upscaling. So this is not really a tight same-tier comparison. It is more a modern card against an older, weaker alternative.

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

GeForce RTX 3070 is the more future-proof choice for 2026 and beyond. You are getting a newer 2020 generation instead of 2008, 1499.7% more raw performance headroom, more VRAM at 8 GB instead of 2 GB, and the stronger feature stack with DLSS Super Resolution instead of FSR upscaling. That leaves it with more room for heavier textures, tougher ray tracing loads, and higher-end 1440p or 4K gaming over the next few years.

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

GeForce RTX 3070 is the smarter buy by a wide margin. GeForce RTX 3070 is about 66.9% more expensive on MSRP at $499 MSRP versus $299 MSRP, and you are getting 1499.7% higher G3D Mark. Radeon HD 4870 really only makes sense now as a very cheap stopgap or a used-market placeholder.

Is Radeon HD 4870 still worth buying for gaming in 2026?

No, not for a fresh gaming build. Radeon HD 4870 is 2008 hardware with 2 GB of VRAM, 1,386 in G3D Mark, and FSR upscaling. That is simply too far behind to be an easy modern recommendation.
