Intel Celeron N2808 vs Intel Celeron N2805

Intel Celeron N2808

► remove from comparison Intel N2808

The Intel Celeron N2808 is a power efficient dual-core SoC for entry-level notebooks. It is clocked at 1.58 - 2.25 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 N2808 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 N2808 is clearly faster than previous Intel Atoms, e.g. the N2800. Depending on the benchmark, the N2808 competes with AMD APUs like the AMD E2-2000. 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 (313 - 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 4.3 watts (3 W SDP). Thus, the chip can be used in compact subnotebooks.

Intel Celeron N2805

► remove from comparison Intel N2805

The Intel Celeron N2805 is a power efficient dual-core SoC for entry-level notebooks. It is clocked at up to 1.46 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.

Performance

Thanks to the improved performance per clock, the Celeron N2805 is faster than previous Intel Atoms, e.g. the N2600. According to our benchmarks, the N2805 competes with AMD APUs like the AMD E1-2100. For very 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 up to 667 MHz, the GPU is even slower than the HD Graphics (Ivy Bridge). Therefore, only very old and less demanding games will run fluently.

Power Consumption

The entire SoC is rated at a TDP of 4.3 watts (2.5 W SDP). Thus, the chip can be used in compact subnotebooks.
