Mobile Processors
If you should have been impressed with Intel’s Pentium 4 plans of reaching the 2 GHz-barrier in Q2/2001 already, the projections in the mobile sector might find your respect as well. In the next quarter (Q1/2001) Intel is planning to release the mobile Pentium III at 900 MHz and 1 GHz, thus being the first supplier of Giga Hertz processors for notebooks in history. Both of those processors will still be running at 100 MHz FSB, as all mobile Pentium II, Celeron and Pentium III processors do for more than 18 months now.
The second quarter next year will see a major change from that, as Intel will release Pentium III processors at 866, 933 and 1000 MHz that are actually based on the ‘Coppermine-T’ core which you already heard of in the first part of the Intel Roadmap Update 10/2000. It is not hard to figure out that those processors will actually take advantage of a front side bus that runs at 133 MHz, thus finally reaching the same front side bus bandwidth as it’s Pentium III brothers in desktop systems. In this second quarter of 2001 we will also see the first mobile ‘Tualatin’-Pentium III processors at 1.13 and 1.26 GHz clock speed, also using 133 MHz FSB. This might be the first official appearance of ‘Tualatin’, since it makes more sense for Intel to supply the mobile market with this 0.13-micron process CPU early, due to its lower power and heat requirements.
Basically we can see Intel pushing the mobile processor market quite hard next year, going from a 850 MHz Pentium III that is available now to 1.26 GHz in only some 6 months. Obviously those new processors and their specs require new mobile chipsets as well, which will be explained in detail further down the article.
The mobile Celeron is not in quite as much of a rush to reach high speeds as its bigger brother Pentium III is. In fact, the mobile Celeron seems to lag behind quite badly. The first quarter of 2001 will see the mobile Celeron 750, Q2/2001 will bring Celeron 800 and Q3 holds Celeron 850. By this time Celeron is far behind Pentium III and you wonder who will be interested in it anymore.
Here’s a list that summarizes the mobile processor roadmap:
- Q1/2001
<ul - Mobile Pentium III 900 MHz and 1 GHz, both at 100 MHz FSB
- Mobile Celeron 750
- Mobile Pentium III based on ‘Coppermine-T’ core (0.13 micron) 866, 933 MHz and 1 GHz, all at 133 MHz FSB
- Possibly Mobile Pentium III based on ‘Tualatin’ core (0.13 micron) 1.13 and 1.26 GHz, also at 133 MHz FSB
- Mobile Celeron 800
- Mobile Pentium III based on ‘Tualatin’ core (0.13 micron) 1.13 and 1.26 GHz, also at 133 MHz FSB
- Mobile Celeron 850
Mobile Chipsets
The evergreen ‘BX’ is finally disappearing very slowly from the desktop market, but it’s still the state-of-the-art chipset in the mobile arena right now. This is supposed to change in the first quarter of next year, when Intel releases i815E-M, the mobile version of ‘Solano’ or i815. While the i815 chipset for desktops supports 133 MHz FSB and PC133 SDRAM, the i815E-M will only support 100MHz FSB and PC100 memory, at least according to the roadmap. The advantages of i815E-M over BX are still obvious. It has a better south bridge, the ICH2, supporting ATA100 and other goodies too. The biggest catch however is of course its integrated 3D-graphics. We have no idea if the performance of this integrated 3D-engine will be even worse than what we know from i815 for desktops, but it will most certainly be a major factor to reduce the costs of a notebook, because there won’t be any need for an additional graphics chip.
Preliminary Specs of i815E-M:
- ICH2-M – ATA100, etc.
- Integrated 3D-graphics
You have certainly read with interest about the transition of future mobile Pentium III processors to 133 MHz FSB and might have wondered which chipset is supposed to support this. The answer is called ‘Almador-M’ or ‘i830-M’ and from this name you can probably figure out its specs already, since it’s obviously the mobile version of the upcoming i830 chipset for desktops, as already discussed in the last two new roadmap articles Intel Roadmap News 10/2000 – Part One, Desktop Processors And Chipsets and HOT! Update Of Intel Roadmap News!. We have no idea if Intel will actually bless the desktop version of Almador with DDR-SDRAM support, and we can also not say if the notebook version will have it. What ‘Almador-M’ will certainly come with is integrated 3D-graphics that’s supposedly faster than i815E-M. The mobile version of Almador is also meant to come with the new south bridge ‘ICH3-M’, which offers support for USB 2.0.
Preliminary Specs of ‘Almador-M’ or i830(E?)-M
- New specs to accommodate Pentium III with ‘Tualatin’-core
- 133 MHz FSB support
- PC133 SDRAM (DDR-SDRAM??) support
- Integrated 3D-graphics
- ICH3-M, USB 2.0
Summary Mobile Products
All in all the future of Intel’s notebook processors and chipsets looks rather bright. Intel is planning to launch the first mobile processor with 1 GHz at the beginning of next year already and the mobile ‘Tualatin’ with up to 1.26 GHz at 133 MHz FSB is supposed to follow some 6 months later.
Manufacturers of graphics chips for notebooks won’t welcome Intel’s latest strategy of supplying mobile chipsets with integrated 3D-graphics. Nobody expects those 3D-graphics to be any kind of useful for real game players, but for the majority of notebook users the graphics of i815E-M and ‘Almador-M’ will be more than good enough, as only few people are using 3D-graphics on notebooks anyway. Thus the majority of company notebooks will probably come without an extra graphics chip, while ‘gamer notebooks’ could be equipped with NVIDIA’s upcoming mobile 3D-chips, of course for a price premium. Long live Intel’s beloved ‘segmentation’.
Future Workstation and Server Products
Workstation And Server Processors
At this stage I actually don’t know how many systems are using Intel’s Pentium III Xeon processors, but you certainly don’t hear much about those Slot2-CPUs, you don’t get many review-requests for them and basically one wonders if Intel is doing any kind of major business with ‘Xeon’. I also remember the time when Intel offered ‘Xeons’ with 133 MHz FSB, which are actually nothing else than a slightly modified Coppermine-Pentium III, although there weren’t any platforms available for these processors at all. Finally the story changed a bit since ServerWorks is offering a chipset that can host Pentium III Xeon processors at 133 MHz FSB. Intel is still not supplying chipsets for this processor, which should be considered odd enough.
Now although ‘Xeon’ seems to spend a life in the shadows, Intel is still having big plans for the next ‘Xeon’-generation, which will obviously be based on the upcoming Pentium 4 core. The high-end version of Pentium 4 is currently known under the name ‘Foster‘ and it is supposed to be launched at 1.7 GHz or more in Q1/2001 for single processor mode only. This Forster-version will be pretty much identical to the normal Pentium 4-core ‘Willamette’, as it is also equipped with 256 kB 2nd level cache and no 3rd level cache at all. The VRM 9.0 voltage spec for Foster is speaking of hefty numbers. The voltage requirement lies between 1.575 and 1.7 V, the maximum current is 60 Ampere and Forster is supposed to be a rather excellent heater element with 62.8 W TDP. It will be using a 603-pin socket, but don’t hold your breath for that anyway, since you bet that this socket will be changed again once ‘Prestonia’ replaces ‘Foster’ shortly after ‘Northwood’ replaces ‘Willamette’. The second quarter of 2001 is supposed to see Foster at 2 GHz or more, this time as single-only as well as dual-processor version, but still with the 256 kB L2-cache only. In Q3 Foster is finally supposed to become a real server CPU. The roadmap is promising full multi processor versions of Foster with 512 kB – 1 MB 3rd level cache, but this time running at 1.3 and 1.4 GHz only. ‘Prestonia’ will probably follow soon, as Q3/2001 is the time when Pentium 4 ‘Willamette’ will be replaced by ‘Northwood’ so we can expect ‘Prestonia right afterwards in Q4/2001.
So far about Intel’s 32-bit processors, but what about the upcoming 64-bit monster by the lovely name of ‘Itanium’? Well, Itanium (is there honestly anyone still interested …?) will actually be released in the next few days, weeks or months, but only as a ‘pilot run’ at some mediocre 733 MHz. Q1/2001 will then see Itanium at the blazing speed of 800 MHz, which will make a lot of people yawn, because at the same time Pentium 4 is supposed to reach 1.7 GHz and thus more than double the clock rate of Itanium. Finally there’s ‘McKinley’, the processor that many see as Intel’s ‘real’ 64-bit processor. McKinley won’t be released before Q4/2001 though, if Intel should stick to its forecast in the 64-bit arena for the first time.
Workstation And Server Chipsets
As we just talked of ‘Itanium’ I just want to mention the chipset for this processor, which is the ‘460GX’. This chipset should already be available and its specs should be known. McKinley will get a new chipset named ‘i870’, which won’t be available before the end of 2001. Unfortunately I can’t give you any details about i870 except one interesting bit. Intel is planning two different versions of i870. One will be for McKinley and thus for IA64 (Intel’s 64-bit technology) and another version will be for IA32 (32-bit).
The workstation version of Foster is supposed to work with the i860-chipset, which will be released in Q1/2001 along with this new Pentium 4 Xeon processor. I expect it to be a beefed up version of i850, which will probably only support RDRAM memory as well.
The server chipset roadmap looks rather odd. Intel is hardly supplying any of the chipsets. The reason for that can only be the unholy Intel-Rambus deal. In the server area there’s simply NO interest in RDRAM-based platforms, so that Intel would have to supply alternative chipsets that support different memory than RDRAM. This would interfere with the Rambus-deal, which is why you can find ‘Third Party’ all over the place in this roadmap slide:
Obviously ‘Third Party’ mostly reads ‘ServerWorks’ right now, but maybe other chipset makers will join.
In the above picture you can also see ‘Plumas’. This looks as if it might be the ‘Xeon’-version of ‘Brookdale‘. In this case ‘Plumas’ is most likely the non-RDRAM platform for ‘Prestonia’ and it might come with DDR-SDRAM support for small servers and workstations.
Finally I’d like to remind you of the ‘i870’ for IA32 story again. The 32-bit version of this 64/32-bit chipset will not work with Foster, but only with Prestonia. Basically you can expect the same story for ‘Foster’ as we’ve also reported for ‘Willamette’. After about 9 months both of those processors will be replaced by ‘Northwood’ and ‘Prestonia’. Thus the package and Slot/Socket used by Foster might also have only a very short life span.
Overall Summary
- Pentium III will continue lagging behind AMD’s Athlon as it will probably take until summer 2001 that there will be a Pentium III faster than 1 GHz. This ‘final’ version of the Pentium III will require a new chipset and Intel might include DDR-SDRAM support into that. It might not as well though. All in all the future of Pentium III doesn’t exactly look rosy, but at least it doesn’t require RDRAM to run this processor.
- The Pentium 4 that will be released in a bit more than a month (‘Willamette’) will only have a very short life span and the only platform available for this processor requires RDRAM. This Pentium 4 as well as its Socket423 will be replaced by ‘Northwood’ and Socket 478 maybe even less than 9 months later. At this time Intel will also supply an alternative to the RDRAM-only chipset by the name of ‘Brookdale’, which might support DDR-SDRAM. The first Pentium 4 by the name of ‘Willamette’ will not be compatible with ‘Northwood’ so that this processor won’t run on ‘Brookdale’-platforms. Basically, you are doomed if you should be the owner of a 3-11 months old Pentium 4 system this time next year.
- The workstation/server pedant of Pentium 4 by the name ‘Foster’ will be released early 2001. The multi-processor version will take a lot longer though until Q3/2001. By the end of 2001 ‘Foster’ will be replaced by ‘Prestonia’, which puts it in the same situation as ‘Willamette’. Chipset-wise you can either go with an Intel workstation chipset that supports RDRAM only, or you can choose SeverWorks or another ‘ThirdParty’ chipset maker. Intel won’t supply anything helpful here.
- The mobile section is the only real enjoyable part of this roadmap. Intel seems to push this area quite hard next year and we can expect a lot of advances.
