RAM prices have experienced significant shifts due to enterprise AI infrastructure demand alongside shrinking DDR4 production lines. While DDR5 adoption continues to grow, its higher kit cost has left PC builders asking a crucial question: Is DDR5 worth the extra money for gaming, or does DDR4 still offer better bang for your buck?
DDR4 vs DDR5: Why the Price-per-Frame Gap Matters
In late 2025, DDR5 systems deliver slightly higher average frame rates, but the steep rise in DDR5 memory prices makes their price-per-frame value worse than DDR4 builds. For gamers focused on value, DDR4 rigs remain the smarter investment, while DDR5 is best for those prioritizing future-proofing.
Full System Build Cost Comparison
To measure real-world value, we evaluated two mid-range gaming builds paired with an RTX 4070 to highlight the platform price difference between DDR4 and DDR5 memory configurations:
| Component | DDR4 Platform Build | DDR5 Platform Build |
|---|---|---|
| CPU | Intel Core i5-12400F (~£130) | AMD Ryzen 5 7500F (~£130) |
| Motherboard | B660 DDR4 Motherboard (~£120) | B650 DDR5 Motherboard (~£200) |
| RAM | 32GB DDR4-3200 Kit (~£90) | 32GB DDR5-5600 Kit (~£280) |
| GPU | GeForce RTX 4070 (~£500) | GeForce RTX 4070 (~£500) |
| Total Estimated Build Cost | ~£840 | ~£1,110 |

Gaming Benchmark Performance (1080p High Settings)
In CPU-bound and memory-sensitive 1080p gaming benchmarks paired with an RTX 4070, DDR5 yields higher overall frame rates, but at a significantly higher cost per frame:
| Game Title | DDR4 Avg FPS | DDR5 Avg FPS | FPS Advantage |
|---|---|---|---|
| Cyberpunk 2077 | 92 FPS | 98 FPS | +6% |
| Baldur’s Gate 3 | 104 FPS | 111 FPS | +7% |
| Call of Duty: MW3 | 144 FPS | 152 FPS | +6% |
| Starfield | 78 FPS | 84 FPS | +8% |
Price-per-Frame Calculation:
- DDR4 System: ~£8.04 per FPS
- DDR5 System: ~£10.00 per FPS
While DDR5 delivers a 6–8% increase in raw frame rates, it requires roughly a 32% increase in total build cost. In terms of sheer performance per pound, DDR4 wins decisively.

DDR4 Advantages & Risks
- Lower Upfront Cost: Budget-friendly motherboards and memory kits free up cash to invest in a faster GPU like our tested desktop graphics cards.
- Competitive FPS: Performance stays within 5–10% of DDR5 in almost all modern titles.
- End-of-Life Platform: Future CPU generations will require DDR5 motherboards, meaning limited direct upgrade paths on existing DDR4 boards.
DDR5 Advantages & Risks
- Higher Bandwidth & Smooth 1% Lows: Improved memory bandwidth reduces frame latency dips in simulation-heavy games.
- Future Platform Upgrades: Compatible with newer socket architectures (such as AMD AM5 or Intel LGA1700/LGA1851 platforms).
- Inflated Pricing: High pricing driven by AI data center demand yields poor immediate FPS-per-pound value.
Final Verdict: Which RAM Should You Buy?
For most gamers, DDR4 systems remain the better short-term value investment thanks to their superior price-per-frame ratio. DDR5 offers smoother frame delivery and long-term future-proofing, but retail price inflation currently turns it into a luxury upgrade rather than a necessity.
