What is the difference between DDR5 vs DDR4?

[Delaney martin]

DDR4 and DDR5 are different generations of Double Data Rate (DDR) synchronous dynamic random access memory (SDRAM) used in computers, servers, and gaming systems. They store and process temporary data, helping your system run applications smoothly.


DDR4 vs. DDR5

1. Speed & Performance

• DDR4: Speeds range from 2133 MHz to 3200 MHz (higher with overclocking).
• DDR5: Starts at 4800 MHz and can go beyond 8000 MHz, providing better multitasking and faster data processing.

2. Bandwidth & Latency

• DDR4: Lower bandwidth (~25.6 GB/s) but slightly better latency.
• DDR5: Up to 51.2 GB/s bandwidth, but higher latency (CAS timings are higher).

3. Power Efficiency

• DDR4: Operates at 1.2V, consuming more power.
• DDR5: Runs at 1.1V and includes built-in Power Management IC (PMIC), improving power efficiency.

4. Capacity & Scaling

• DDR4: Maximum 32GB per module.
• DDR5: Supports up to 128GB per module, making it more scalable for future applications.

5. Compatibility & Cost

• DDR4: Compatible with older and current-generation motherboards (Intel 10th/11th Gen, AMD Ryzen 5000).
• DDR5: Requires newer motherboards (Intel 12th/13th/14th Gen, AMD Ryzen 7000 series).
• Price: DDR5 is more expensive due to its advanced technology.
