Comparison of the two processors

In this comparison, the Intel Celeron J3455 released in the third quarter of 2016 competes against the Intel Celeron J4125 released in the fourth quarter of 2019. These two processors are manufactured with a structure width of 14 nanometers, but the Intel Celeron J3455 is still based on the older "Apollo Lake" microarchitecture, whereas the Intel Celeron J4125 is already based on the newer "Gemini Lake Refresh" architecture.

Both processors have 4 physical cores. In the Intel Celeron J3455, the cores have a base clock frequency of 1.50 gigahertz and a maximum turbo clock frequency of 2.30 gigahertz. The base clock frequency of the Intel Celeron J4125 is significantly higher at 2.00 gigahertz and the maximum turbo clock rate of 2.70 gigahertz is also higher than that of the Intel Celeron J3455. The processors do not support Hyper-Threading-Technology and neither of them can be overclocked.

The Intel Celeron J4125 achieves 40 percent higher performance than the Intel Celeron J3455 in both the single-core and multi-core benchmarks.

The processors both have an internal graphics unit. The Intel HD Graphics 500 is used in the Intel Celeron J3455. This graphics unit comes from the ninth generation of Intel's iGPUs and clocks at up to 0.75 gigahertz. It has 12 execution units with 96 shaders, is manufactured using the 14 nanometer process and the maximum GPU memory size is 8.00 gigabytes. The Intel UHD Graphics 600 from generation 9.5 is used in the Intel Celeron J4125. This graphics unit also has 12 execution units with 96 shaders and supports a GPU memory size of up to 8 gigabytes. Based on the FP32 computing power, which is 144 gigaFLOPS, you can see that the two iGPUs are on the same level in terms of performance, but the Intel UHD Graphics 600 supports, for example, both the coding and the encoding of the HEVC codec in hardware.
