Intel Pentium N3520

Intel N3520

The Intel Pentium N3520 is a power efficient quad-core SoC for entry-level notebooks. It is clocked at 2.17 GHz base clock and can boost up to 2.42 GHz (Burst clock speed). The pentium is part of the Bay Trail-M platform. Thanks to the specially optimized 22 nanometer low-power process (P1271) with tri-gate transistors, performance and energy efficiency have been significantly improved compared to previous Intel Atom CPUs.


The processor cores are based on the new Silvermont architecture, which is an out-of-order design for the first time. The increased utilization of the pipeline and many other improvements (optimized branch prediction, increased buffers, enhanced decoders) have increased the performance per clock by about 50 percent. At the same time, however, the Hyper-Threading feature of the previous generation has been removed. Other major changes are the support for new instruction set extensions such as SSE 4.1 and 4.2 as well as AES-NI (depending on the model).


Thanks to 4 CPU cores and a clock speed of up to 2.4 GHz, the Pentium N3520 is significantly faster than previous Intel Atoms, e.g. the N2800. On average, the N3520 performs somewhere between the AMD Kabini APUs AMD A4-5100 and A6-5200. For everyday tasks such as Internet or Office the performance is adequate, but not for very complex software or modern games.


The HD Graphics (Bay Trail) is based on the Intel Gen7 architecture, which supports DirectX 11 and is also found in the Ivy Bridge series (e.g. HD Graphics 4000). With only 4 EUs (Execution Units) and a relatively low clock speed of 313 - 854 MHz, the GPU is even slower than the HD Graphics (Ivy Bridge). Therefore, only older and less demanding games will run fluently. Compared to the HD Graphics in the slower Pentium N3510, the N3520 is clocked 14 % faster (750 vs. 854 MHz).

Power Consumption

The entire SoC is rated at a TDP of 7.5 Watts (4.5 SDP - Scenario Design Power). Thus, the chip can be used in compact subnotebooks and convertibles and doesn't require extensive cooling.
