Chip giant Intel has been busy this week, releasing a raft of new notebook processors across all notebook market segments.

At the top end of the market, the company released three new Core i7 processors – the i7-940XM, i7-840QM and i7-740QM chips at US$1096, $US568 and US$378 each per thousand respectively.

The Core i7-940XM is a true quad-core chip with eight threads clocking in at 2.13GHz. With Intel’s TurboBoost technology, the top clock speed of this chip is 3.33GHz. It also features 8MB of smart cache memory. The on-board memory controller can handle up to 8GB of DDR3-1333 memory but the chip has no integrated graphics on-board.

The chip is built on Intel’s older 45-nanometre lithography and has a 55-watt total power displacement.

The Core i7-840QM is another quad-core/eight-thread CPU with a clock speed of 1.86GHz. TurboBoost increases this to 3.2GHz on single-threaded applications. It too has 8MB of smart cache while the on-board memory controller can handle 8GB of DDR3-1333 memory. Again, there’s no integrated graphics here. The maximum TDP rating here is 45-watts.

The Core i7-740QM is the slowest of the new quad-core CPUs with eight threads and a clock speed of 1.73GHz. TurboBoosting gets this up to 2.93GHz with supported applications. This one only has 6MB of smart cache but again, the memory controller handles 8GB of DDR3-1333 memory. No integrated graphics option is on-board.

In the entry-level market, Intel has pushed out the new Celeron U3400. This dual-core ultra-low-power processor features two threads and a clock speed of 1.06GHz. You get 2MB of smart cache while it includes a DDR3 memory controller for up to 800MHz RAM. This one comes with Intel integrated HD graphics engine with a base clock of 166MHz. The chip has a TDP of just 18-watts and sells for $134 per thousand.
