Ryzen 5 3500U vs Ryzen 7 3750H


Description
Both models 3500U and 3750H 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 3500U gets a score of 141 k points while the 3750H gets 175.2 k points.

Summarizing, the 3750H is 1.2 times faster than the 3500U. To get a proper comparison between both models, take a look to the data shown below.

Non-optimized benchmark
The benchmark in Mode 0 (FPU) measures cpu performance with non-optimized software. It uses the basic µinstructions from the i386 architecture with the i387 floating point unit. This mode is compatible with all CPUs so it's practical to compare very different CPUs

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.
