Ryzen 7 2700X vs Ryzen 5 3400G


Description
Both models 2700X and 3400G are based on Zen+ architecture.

Zen+ is the second generation of Ryzen processors. It uses the 12nm process by GlobalFoundries. Other than that, the die is the same than first generation Zen. It comes with 64kB of L1 cache and 512kB of L2 cache per core. There are 3 variants: Pinnacle Ridge (desktop), Colfax (high-end desktop) and Picasso (APU).

Using the multithread performance as a reference, the 2700X gets a score of 433.2 k points while the 3400G gets 200.3 k points.

Summarizing, the 2700X is 2.2 times faster than the 3400G. To get a proper comparison between both models, take a look to the data shown below.

AVX2 optimized benchmark
The benchmark in mode III (AVX2), like AVX1, is optimized to used 256 bits registers beside the second version of the Advanced Vector Extensions (AVX). The first AVX2 compatible CPU was released in 2013.

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.
