About
Benchmark results data are provided for various DDR4 memory models. This collection of data is essential for comparing multiple RAM kits by evaluating their performance based on a standardised series of tests. It is particularly useful for individuals engaged in purchasing components for or assembling a new personal computer. An enhanced version of this data collection is noted as being available separately.
Columns
- Memory Name: The specific name of the memory product, featuring 4,264 unique identified values.
- Model: The model associated with the memory product, featuring 4,264 unique identified values.
- Generation: Identifies the memory type; all records currently indicate DDR4 SDRAM.
- Latency (ns): Measures the Latency Time in nanoseconds, where lower values signify superior performance. The mean latency is approximately 34.4 ns, with observed values ranging up to 374 ns.
- Read Uncached (GB/s): Represents the Read Uncached Transfer Rate in gigabytes per second, where higher values indicate better performance. The mean transfer rate is 16.1 GB/s, with a maximum recorded rate of 26.4 GB/s.
- Write (GB/s): Represents the Write Transfer Rate in gigabytes per second, where higher values indicate better performance. The mean transfer rate is 12 GB/s, with a maximum recorded rate of 22.2 GB/s.
- Price (USD): The Current Market Price, specified in United States Dollars. Note that 85% of records are missing price data; the mean price for available records is $244, ranging up to $1,000.
Distribution
The data is contained within a CSV file named DDR4_RAM_benchmark_v3.csv, which is 242.73 kB in size and structured across 6 columns. There are 4,264 records detailing various memory models. This data collection is not expected to receive future updates.
