Deschutes Slot 2

The 'Deschutes' will be a Pentium II that will run at 100 MHz bus clock and come with a so called 'CSRAM ' 2nd level cache that will run at CPU clock rather than 1/2 CPU clock in the Pentium II. This shall increase the performance by 10% over the Pentium II at the same clock speed. The Deschutes will be able to cache up to 4 GB RAM and can run in up to quad CPU configuration , so that it's mainly targeted to server systems in the first place. This CPU will need a new slot , which will probably be called 'Slot 2 '. This Slot has got considerably more contacts, but by placing the contacts in three rather than two rows above each other, the cartridge won't be much bigger than the Slot 1 SEC. The Deschutes is planned to be launched as a 400 MHz version sometimes in the 2nd quarter next year and will need the upcoming 450NX chipset on its motherboard. A 450 MHz version will follow in the second half of 1998.

Pentium II

The Pentium II will come in a 333 MHz version early 1998 which will still run at 66 MHz bus clock. The next steps will be a 350, 400 and 450 MHz version in the following quarters, all running at 100 MHz bus clock , requiring the 440BX chipset to support this new bus clock. As it seems, only the 100 MHz bus clock version will include a different tag RAM to give the Pentium II the ability to run with more than 512 MB properly. The Pentium II will only be able to run in up to dual CPU configurations .

Mobile Pentium II

A special low power version of the Pentium II for mobile systems will be seen beginning next year for the first time. This CPU will probably come with a smaller L2 cache and it shall run at less than 2.5 V. CPU speeds will range from 233 up to 300 MHz .

Pentium Pro

The Pentium Pro w/ 256 kB L2 cache for normal desktop systems will soon go out of production . The roadmap only talks of this CPU until end of this year. Since Intel doesn't have a Pentium II solution for server systems until 2nd quarter 1998, you will be able to get the Pentium Pro w/512 and 1 MB L2 cache until this time.

The roadmap doesn't speak of the upcoming Pentium Pro Overdrive however, which will be a Pentium II for Socket 8 . This CPU could increase the life span of Socket 8 boards beyond 1998.


The Tillamook should be seen in the shelves pretty soon, since the roadmap is placing it in the current quarter of 1998. This CPU will be a Pentium MMX shrunk to 0.28 micron die size and therefore requiring much less power and less voltage. This CPU is targeted to the mobile systems market, but the 266 MHz version expected early next year will be interesting for desktops as well.

Pentium mmX

The well known Pentium MMX will only as 233 MHz version see the second quarter of next year. All slower versions will slowly but surely go out production until then, starting with the Pentium MMX 133 MHz which won't be produced next year anymore.

Pentium Classic

The good old Pentium Classic will soon disappear . The 166 MHz and slower versions will only be produced until end of September, the Pentium Classic 200 will go out of production by the end of this year.
