Intel Pentium 977 vs Intel Pentium B980

Intel Pentium 977

► remove from comparison

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 B980

► remove from comparison Intel B980

The Intel Pentium B980 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 B980 integrates a graphics card called Intel HD Graphics that is based on the desktop HD Graphics 2000 clocked at 650 / 1150 (with Turbo Boost).

The performance of the Pentium B980 should be clearly faster than a similar clocked Arrandale Pentium CPU. Due to the high clock speed, the missing HyperThreading and smaller last level cache should be equalized and therefore, the performance should be similar to a Intel Core i3-2310M with 2.1 GHz.

The 35W TDP rating includes the integrated GPU and DDR3-1333 memory controller.
