Despite taking advantage of faster 1600MHz memory, the Pentium N3700 is still quite a bit slower than the Pentium J2900. Here we see a 9% reduction in memory bandwidth despite using 20% higher clocked memory. The drop in bandwidth is due to the fact that the N3700 is clocked between 10 and 33% slower than the J2900.
Interestingly, although the Celeron N3050 is also clocked much lower than the Celeron J1800, it delivered the same 6.6GB/s memory bandwidth.
The lower clock speed really hurts the Pentium N3700 as it is 27% slower than the J2900 when measuring L1 cache performance and 29% slower when comparing L2 cache performance. The Celeron N3150 also struggled as it was 33% slower than the Celeron J1800.
