Celeron N3450 vs J3455


Description
Both models N3450 and J3455 are based on Goldmont architecture.

Goldmont is a low power architecture intended for Atom, Celeron and Pentium CPUs used in SoCs. It has between 2 and 4 cores and uses the 14nn process.

Using the multithread performance as a reference, the N3450 gets a score of 39.3 k points while the J3455 gets 47.3 k points.

Summarizing, the J3455 is 1.2 times faster than the N3450. To get a proper comparison between both models, take a look to the data shown below.

SSE3 optimized benchmark
The benchmark in mode I (SSE) is optimized for the use of SIMD instructions with 128 bits register and the SSE set up to version 3. Nearly every modern CPU has support for this mode.

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.
