Ryzen 7 1800X vs 1700X


Description
Both models 1800X and 1700X are based on Zen architecture.

Zen is the first Ryzen generation. It uses 14nm FinFET process from GlobalFoundries. It has support for DDR4 memory and ECC. Comes with 64kB instruction + 32kB data L1 cache and 512kB L2 cache per core.

Using the multithread performance as a reference, the 1800X gets a score of 410.5 k points while the 1700X gets 372.7 k points.

Summarizing, the 1800X is 1.1 times faster than the 1700X. To get a proper comparison between both models, take a look to the data shown below.

Monothread performance graph
Monothread performance graphics gives the performance vs time. They are useful to measure the time it takes to the CPU to reach the maximum performance.

Usually, CPU's performance will be steady during these tests but if it has a slow frequency strategy, the first samples will show a lower score.

Multithread performance graph
Multithread graphs measure the performance against a heavy load during certain time.

If CPU's TDP doesn't limit the frequency and the machine is properly cooled, performance should remain steady vs time. Otherwise, the performance score will oscillate or decrease over time.
