Mobility Radeon HD 4870

2009

Why buy it

✅100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).
✅Draws 30W instead of 180W, a 150W reduction.

Trade-offs

❌2009 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
92.9% HIGHER MSRP
$299 MSRPvs$155 MSRP
❌Lower G3D Mark per dollar, at 2.4 vs 4.8 G3D/$ ($299 MSRP vs $155 MSRP).

Radeon R7 A10-7800

2024

Why buy it

✅Costs $144 less on MSRP ($155 MSRP vs $299 MSRP).
✅Delivers 98.3% more G3D Mark for each dollar spent, at 4.8 vs 2.4 G3D/$ ($155 MSRP vs $299 MSRP).
✅Better long-term bet: RDNA 3.0 (2022−2026) on 5nm gives it a newer hardware base for upcoming games.

Trade-offs

❌Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
❌500% higher power demand at 180W vs 30W.
