DDR5 won't fix your 1% lows.

Not really. The difference in 1% low fps between DDR5 and DDR4 in Cyberpunk 2077 is usually within a few percent — single digits. That’s not enough to smooth out stutters.

DDR5’s main advantage is raw bandwidth, which helps average fps in CPU-bound scenes. But 1% lows (the frame drops) are more about how fast the CPU can fetch data from cache and main memory — latency matters here, and DDR5 actually has worse latency than well-tuned DDR4. Some games even stutter more on early DDR5 kits because of timing penalties.

Open-world games like Cyberpunk are heavy on draw calls, NPC AI, and streaming. Those hit the CPU’s cache limits long before DDR5 bandwidth kicks in. A faster GPU or a newer CPU (especially with more L3 cache, like the 3D V-Cache AMD chips) will do way more for 1% lows than swapping your RAM kit.

If you’re building new and DDR5 is the same price, get it. But if you’re on DDR4 and wondering if a RAM upgrade will fix stutters — it won’t.

Save the money for a better graphics card or a CPU with bigger cache.
