Intel Celeron N2840 vs Intel Celeron N3000 vs Intel Celeron N2806
Intel Celeron N2840
► remove from comparison
The Intel Celeron N2840 is a power efficient dual-core SoC for entry-level notebooks. It is clocked at up to 2.58 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 N2840 supports Intel Quick Sync and 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, the Celeron N2840 is faster than previous Intel Atoms, e.g. the N2850. Depending on the benchmark, the N2840 competes with older dual core CPUs like the Intel Core 2 Duo series. For simple everyday tasks such as Internet or Office the performance is adequate, but not for complex software or modern games.
Graphics
The graphics unit of 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 up to 792 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 subnotebooks.
Intel Celeron N3000
► remove from comparison
The Intel Celeron N3000 is a low-end dual-core SoC for notebooks, which has been presented in April 2015. It is clocked at 1.04 - 2.08 GHz and part of the Braswell platform. Thanks to its new 14 nanometer low-power process (P1273) with tri-gate transistors, energy efficiency has been significantly improved compared to its predecessor Bay Trail (e.g. Celeron N2840). In addition to the CPU cores, the SoC offers a DirectX 11.2-capable GPU as well as a DDR3L Memory Controller (2x 64 bit, 25.6 GB/s).
Architecture
The processor cores are based on the Airmont architecture, which is basically a slightly modified shrink of the previous Silvermont core. While performance per clock (IPC) has not been improved, the more efficient 14 nm process may lead to a better utilization of the CPU Burst (alias Turbo Boost) and therefore a somewhat higher performance in certain situations.
Performance
Due to only two CPU cores, low clock rates and the weak IPC, the Celeron N3000 is not sufficient for demanding applications and may even struggle on complex websites. Overall, performance is similar to the old Celeron N2810.
Graphics
The HD Graphics (Braswell) is based on the Intel Gen8 architecture, which supports DirectX 11.2 and is also found in the Broadwell series (e.g. HD Graphics 5300). With 12 EUs (Execution Units) and a clock speed of up to 600 MHz, the GPU is significantly faster as the HD Graphics (Bay Trail), but still not powerful enough to handle modern 3D games. The GPU also supports 4K/H.265 video acceleration.
Power Consumption
The entire SoC is rated at an TDP of 4 watts (SDP 3 watts). Thus, the chip can be cooled passively.
Intel Celeron N2806
► remove from comparison
The Intel Celeron N2806 is a power efficient dual-core SoC for entry-level notebooks. It is clocked at 1.6 - 2.0 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.
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.

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, the Celeron N2806 is faster than previous Intel Atoms, e.g. the N2800. Therefore, the N2806 competes with entry-level AMD APUs like the AMD E1-1200. For simple everyday tasks such as Internet or Office the performance is adequate, but not for more complex software or modern games.
Graphics
The graphics unit of 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 - 756 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 4.5 watts (2.5 W SDP). Thus, the chip can be used in passively cooled subnotebooks.
