Intel Pentium 977 vs Intel Pentium B940

Intel Pentium 977

► remove

The Intel Pentium 977 is an Ultra Low Voltage (ULV) dual core processor for entry-level laptops. It is based on the Sandy Bridge architecture but many of the features like Turbo Boost, Virtualization (VT-x, VT-d), HyperThreading, AES or Trusted Execution are deactivated. The Pentium 977 integrates a graphics card called Intel HD Graphics that is based on the HD Graphics 2000 and clocked from 350 - 1000 MHz.

The performance of the Pentium 977 is a bit above a similar clocked Arrandale Pentium CPU and therefore higher than a 1.3 GHz Pentium U5600.

The 17W TDP rating includes the integrated GPU and memory controller and therefore the 957 is suited for small subnotebooks.

Intel Pentium B940

► remove Intel B940

The Intel Pentium B940 is a dual core processor for entry-level laptops. It is based on the Sandy Bridge architecture but many of the features like Turbo Boost for the CPU part, HyperThreading, AES, Virtualization (VT-x and VT-d), Trusted Execution or Intel Quick Sync are deactivated. The Pentium B940 integrates a graphics card called Intel HD Graphics that is based on the HD Graphics 2000 clocked at 650 / 1100 (with Turbo Boost).

The performance of the Pentium B940 should be faster than a similar clocked Arrandale Pentium CPU like the Intel Pentium P6100 due to the architectural changes in the core. In our benchmarks, the B940 was even faster than an old P6200 with 2,1 GHz.

The 35W TDP rating includes the integrated GPU and memory controller.
