Intel Celeron N2840 vs Intel Celeron N2920

Intel Celeron N2840

► remove Intel N2840

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 N2920

► remove Intel N2920

The Intel Celeron N2920 is a power efficient quad-core SoC for entry-level notebooks. It is clocked at 1.86 - 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. 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 N2920 is significantly faster than previous Intel Atoms, e.g. the N2800. On average, the N2920 competes with AMDs Kabini APU 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 up to 844 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 and doesn't require extensive cooling systems.
