Intel dumbs down dual Santa Rosa cores with IDA

Notebook Roadmaps Santa Rosa Meroms get better Vista Aero support

CHIP FIRM Intel will add an extra tick box to a range of Merom 65 nanometre Santa Rosa chips it is readying.

The T7700, the T7500, the T7300 and the T7100 will have IDA, which stands for Intel Dynamic Acceleration.

What is IDA? Apparently it allows extra performance without adding anything to the bill of materials (BOM) and also keeps to 35W for standard voltage, 17W for low voltage and 10W for ultra low voltage chips.

Intel claims that when single threaded apps or multi-threaded apps with extended serial code are executed, IDA gives additional performance benefits.

One core puts its feet up while the other one works like a donkey, with IDA active only when one bit of code is up for execution. Meanwhile, multiple apps can be open and hang around smoking tabs and gossiping around the water cooler.

The Santa Rosa L7500, L7300, U7600 and U7500 CPUs will all come equipped with IDA.

Intel has also told its pardners that it will add support for a graphics render clock frequency for its Crestline GM chipset within current power ratings. The GFX-500MHz will give better performance and is aimed at satisfying the demands of Microsoft Vista Aero. For example, the 13.5W Merom standard voltage chips with an 800MHz system bus will support 500MHz and 400MHz frequencies.

Meanwhile, Intel is keeping to its last and has no plans afoot as yet to cut prices on its existing dual core notebook chips. It will intro a 520 1.6GHz Celeron notebook with 1MB of cache on Hogmanay, along with a mobile ULV 443 1.20GHz Celeron at $135 and $160 respectively. On that day it will also introduce the 4MB cache L7400 (1.50GHz, 667MHz) at $318, the L7200 (1.33GHz/667MHz) at #285, and the the Core Solo ULV U1500 (1.33GHz/533MHz/2MB) at $262. It has also changed the price of the Windigo 1965HSD to $139. µ
