as we knew Intel just launched three processors in a new family called Nehalem, one of which is an Extreme Edition version.
Let’s see what differences between them.
Features of Intel Core i7
- Hyper-Threading
- Turbo Boost
- 8MB Intel Smart Cache
- Integrated Memory Controller with support for 3 channels of DDR3-1066MHz memory
- Intel QuickPath interconnect to Intel X58 Express Chipset
- Intel X58 Express Chipset
- PCI Express 2.0 discrete graphics flexibility for multiple graphics card configurations
- Intel HD Audio Support
- 6 SATA ports at 1.5Gbps and 3Gbps speeds and 12 USB 2.0 ports with 2 independent EHCI controller

- 3.2GHz Clock Speed
- 6.4GT/second QPI speed
- 8MB L3 cache
- DDR3-1066
- 3 channel support
- TDP 130W
- Overspeed Protection Removed - Yes
- 45 nanometer(nm) process
- Nehalem core
- Selling Price $999 (RM 3,610)
Intel Core i7-940
- 2.93GHz Clock Speed
- 4.8GT/second QPI speed
- 8MB L3 cache
- DDR3-1066
- 3 channel support
- TDP 130W
- Overspeed Protection Removed - No
- 45 nanometer process
- Nehalem core
- Selling Price $562 (RM 2,030)
Intel Core i7-920
- 2.66GHz Clock Speed
- 4.8GT/second QPI speed
- 8MB L3 cache
- DDR3-1066
- 3 channel support
- TDP 130W
- Overspeed Protection Removed - No
- 45 nanometer process
- Nehalem core
- Selling Price $284 (RM 1,026)
The main differences between the three CPUs are: Overspeed Protection, the transfer rates of the Quick Path Interface and the clock speed, as otherwise the three CPUs are identical.
