Intel Pentium J2850
The Intel Pentium J2850 is a power efficient quad-core SoC for desktops and nettops. It is clocked at up to 2.4 GHz and part of the Bay Trail-D 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 its predecessor.
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 J2850 is significantly faster than previous Intel Atoms, e.g. the D2560. Presumably, the J2850 even beats some of the Kabini APUs like the AMD A4-5000. 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 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.
The entire SoC is rated at a TDP of 10 watts. Thus, the chip can be used in compact nettops.
