Intel phases out 45nm CPUs to make way for Sandy Bridge -

Intel has announced that it will begin phasing out 21 45nm processors to make way for new products as it gears up for the launch of the much vaunted Sandy Bridge processor early next year.

A product discontinuance notice (PDN) has already been issued earlier this quarter for its Core i7-975X which will see its end of life (EOL) cycle commence in the first quarter of next year, and the Core i5-750 will have a PDN issued in the first quarter of next year, and EOL following in the third quarter.

Four 45nm quad-core processors including Core 2 Quad Q9650 have already received PDN earlier in this quarter, five more quad-core processors are will be issued PDN in the third quarter, including Core Quad Q9300 and Q8400.

Two dual-core processors – Core 2 Duo E8600 and E8600 – will see PDN in the third quarter, while both E7500 and E7600 will have PDN in the second quarter and EOL in the fourth.

The entry-level Pentium range will also see PDNs issued, the E5600 will see OPDN in the second quarter and EOL in the third, while both the E5600 and E6600 have PDN in the first quarter of 2011.  The E6300 has already been issued with PDN.

As for Celeron processors, E3200 will see PDN in the first quarter, while the E3300 will do so in the fourth quarter of 2011.

This will allow Intel to launch in the region of ten new processors which will include quad-cores such as the Core i7-2500 and 2600, along with Core i5 2300 and 2400.  It will also include dual-core Core i3-2120 and 2100.

It is thought that the dual-core processor will consume just 65W, with the quad reaching 95W, while there will also be a Core i3-2100T with only 32W TDP for mini-ITX motherboard and all-in-one PC, according to Digitimes.

Meanwhile AMD have given us an idea of the performance levels of the Bobcat chips in its rival Fusion platform which apparently boasts even lower power consumption.

Comparing AMD’s dual core chips it was shown that 1.6GHz E-350 Zacate CPU was on par overall with the 2.1GHz Athlon P320-based Danube system, while the new chip was ahead when tested in 3D Mark Vantage and PC Mark Vantage. The test also provided similar results for the 1.3GHz Athlon II Neo K325 based Nile system which excelled when performing tasks where GPU power is required, though less impressive in CPU intensive tasks.

Single core chips also provided similar results which give the shows that AMD focusing on power draw, with the Danube platform intended for notebooks with a TDP of 25W, while the Nile chips are designed for ultraportables with 12W TDP.  This should greatly reduce the amount of heat generated while increasing battery life, though how they will compare to the new Intel chips in terms of processing power remains to be seen.

AMD will also be releasing its 16-core server platform based in the Bulldozer core, named the Interlagos processor, which features up to 16 cores and 4 channels of DDR-3 memory.  An 8-core, 2-channel processor code-named Valencia will be suitable for smaller clusters where power or price are concern. 

The Bulldozer is the first new server processor core technology from AMD since the AMD  Opteron processor, featuring a modular design with 256-bit floating point capabilities and other features that enable high performance computing.
