Celeron J3455 vs Core i7-840QM benchmarks
Our benchmark analysis concludes that the Core i7-840QM performs better than the Celeron J3455. Despite this, the Celeron J3455 has the advantage in our gaming benchmark.
Our spec comparison shows that they have an identical amount of cores but the Core i7-840QM has more threads. Our comparison shows that the Core i7-840QM has a slightly higher clock speed compared to the Celeron J3455. A Celeron J3455 CPU outputs less heat than a Core i7-840QM CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.
Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Celeron J3455 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
