The Intel Celeron N2930 is a power efficient quad-core SoC for entry-level notebooks. It is clocked at 1.83 - 2.16 GHz and 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 N2930 supports Quick Sync as well as Wireless Display.
Architecture
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).
Performance
Thanks to the improved performance per clock and the 4 cores, the Celeron N2930 is significantly faster than previous Intel Atoms, e.g. the N2800. Depending on the benchmark, the N2930 competes with AMD Kabini APUs like the A4-5000. For most everyday tasks such as Internet or Office the performance is adequate, but not for complex software or modern games.
Graphics
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.
Power Consumption
The entire SoC is rated at a TDP of 7.5 watts. Thus, the chip can be used in compact (and sometimes even passively cooled) subnotebooks and tablets.
