Foreign media test Intel platform DDR4/DDR5 memory performance: average gap of 11% to 14% across 15 games - IT Home

Tom's Hardware benchmarked Intel LGA 1700 CPUs with DDR4 vs. DDR5 in 15 games at 1080p using an RTX 5090.

DDR5 generally beat DDR4 by about 11% to 14% on average, with some titles exceeding a 20% lead.

The performance gap was larger on higher-end chips such as the Core i9-14900K, showing memory choice can meaningfully affect gaming results.

For Intel LGA 1700 systems, DDR5 offers a clear gaming advantage over DDR4, especially on faster processors.
