Eee PC to be without secondary cache?
July 8th, 2007 by antThere’s an interesting article comparing the OLPC, Asus Eee PC, Foleo, and Nanobook. Interestingly, the Eee PC does not receive positive thoughts, specifically with speculation that the 900mhz processor does not have secondary cache. The author insists that this will result in crawling speeds.

That sucks. Can anyone confirm that this will be the case? No second cache… I was thinking this was going to be the answer to many of my needs.

Its worth noting that both the Dothan pentium-m and the McCaslin have L2 cache. Its all currently speculation about the processor in the eee pc, so we shall just have to wait and see.
But even without the L2 cache, its going to be faster than any ARM based system, so its going to be worth a look.

Besides which, this is the Inquirer we’re talking about. They apparently can’t be bothered to supply a source or provide any indication as to where their information is coming from.

According to wiki all the dothan CPU’s have L2’s, I don’t have a clue what the Inquirer guy is rambling on about, in fact the only CPU’s that Intel has made that don’t have some L2 is the very first two celeron CPUs which are not mobile. Further more, I have found a Dothan with a clock at 900Mhz,(someone in the forum said they didn’t make one) its here

the Celeron M ULV 353, it only has 512KB of L2, but thats better than none

It’s not very clear whether that particular sentence refers to Eee PC or to Intel’s Classmate… the way it’s written, it seems aimed at the Classmate, but I could be wrong.
July 8th, 2007 at 7:29 pm
Well. Many think this EEE will be similar if not identical in specifications to the Classmate PC. It’s all speculation right now though. But, it does seem probably that the two will share a lot of features. http://en.wikipedia.org/wiki/Classmate_pc

I’m confident it will have (some) L2 cache. As others have pointed out all Dothans have L2’s and they have demonstrated it with KDE I think which requires quite lot of processing power.

If you look on the Classmate PC hardware description page: http://www.classmatepc.com/classmatepc-system-hardware.html it states Zero L2 cache.
Until we get more information on the EeePC I would assume it’s the same chip as the Classmate - for volume reasons.
How this affects performance on the device is open to speculation. Obviously cache would be nice, but I don’t think it would significantly impact it’s performance in target market.

If it were the same components then why does the Classmate have a 915 intel chipset while the Eee is supposd to have a 910 intel chipset?
July 9th, 2007 at 4:04 pm
hmm, i have an old pentium-m 2.0ghz (533mhz fsb) that would run at 1.5ghz on the 400mhz fsb… think there’s any chance that the cpu will have a proper socket/be removable? with space and cost at a premium, it’s probably likely that they’ll solder the chip on there, but here’s hoping that i’ll be able to swap a slightly faster chip in there…
July 9th, 2007 at 5:22 pm
gongo the chances are slim to none for many reasons too boring to share.
July 9th, 2007 at 10:45 pm
One, this is the inquirer… they are NEVER right.
Two, the PC701 was announced with a dothon which all have cache, not the celeron
three, the artical says that the the Via cpu would be faster. to anyone who pays attention. Via cpus are always slow….
Don’t listen pay attention to this, we’ll get cache

After taking a look at the intel classmate specifications (and taking into account the price of the Eee PC):
http://www.intel.com/intel/worldahead/pdf/CMPCbrochure.pdf (check Page 3)
I would also assume that the EeePC is likely using the same chipset & CPU as the intel classmate as the similarites of the components are too great to ignore.
Now, in my opinion a 900Mhz Dothan/Celeron M based CPU without any level 2 cache that is connected to a DDR 2 memory bus is without a doubt faster than any XSCALE CPU available today. Level 2 cache or not, running non 3D desktop and multimedia applications on such a CPU/chipset platform in linux or XP would not be a problem.
If you want to do speedy video re-conversions, or folding, or CAD while on the go, get a ‘real’ notebook PC. I for one, am still getting the 7inch Eee PC if it costs
July 10th, 2007 at 3:17 am
I am now 100% certain that the CPU & Chipset used is exactly the same as that in the Intel Classmate PC:
“…It’s going to have the Classmate PC brand on it, but it will be sold and shipped by Asus,” Maloney* said, calling the notebooks a complement to Intel’s current Classmate PC line…”
Check this site article from June 5th regarding the Eee PC:

*Sean Maloney is an Intel Rep. that was at Computex in Taiwan.

That’s a rather specious conclusion. Complementary == identical?
July 10th, 2007 at 2:43 pm
This is my last comment until I get my hands on the 701.
Is the Classmate PC identical to the Asus Eee PC 701? Of course not, is it more than likely that they feature the same reference platform and core components, most definitely.
My take:
With the Eee PC, Asus is essentially taking a subsidized platform intended to provide people in developing countries with a notebook, replacing the notebook’s chassis w/ some peripheral modifications and marketing it to everyone.
I highly doubt that ‘Classmate PC’ branded notebooks like the Eee PC will feature the new (rumored alternative CPU) A100/A110 CPUs w/L2 cache, because…
A) A100/A110 CPUs require the i945 chipset.
B) They are undoubtedly more expensive than the Celeron M ULV sans L2 cache.
C) Asus has been using 900mhz Celeron M ULV sans L2 cache in the R2H UMPC for quite sometime now, so they obviously have ‘stock’ (possibly overstock, now with the release of the R2H-V) of that particular CPU.
Intel would not have created a new processor that would make its debut in the Asus’ Eee PC without a CPU specific press release. So other than their 900 Mhz Celeron M ULV for Classmate PC branded notebooks and older UMPC’s…what ‘unknown’ 900mhz i910/i915 compatible CPU do you think it is using? - I think it is obvious that there is not another CPU being used.
Do you guys really think a 900 Mhz Dothan based CPU (Celeron M) sans L2 cache w/512MB DDR2 memory running KDE or XP UI won’t be able to handle SD videos without PP? or play some MP3’s while rendering CNN.com in a couple of seconds?, or search through a thousand emails in outlook in a reasonable amount of time? or for the technically inclined…act as a responsive mini-web or file server? If so…I’m amazed, and think that some of you need to recall what you or others were doing several years ago in XP on a 450 mhz P2 with likely half the amount of RAM…

IMHO, to balance the lack of cpu power, we have SSD that is faster then HD, and an optimized (I hope…) Linux version.
People that played with Eee PC didn’t complain about machine’s performance… I even read somewhere that boot time is only 15 seconds…
And we always have Damn Small Linux… “Run light enough to power a 486DX with 16MB of Ram!”
Where’s my Eee PC !!!!

+1 for Julio’s comment
Right now I’m sitting at my job in front of 900MHz Pentium + 256MB of SDRAM + Windows XP with VirtualBox running 3 Linux systems at the same time.
Sure, without L2 it would be slower, but hey, I won’t use Eee for such tasks either.
July 11th, 2007 at 11:58 pm
SSD boots faster but over all preformence is worse then a standard hard drive. the reason there using SSD is because its solid, no moving hard drive parts to break
i’m personally keeping my 60gb laptop drive with me at all times to keep files on as well as a 4gb SD card in the laptop to increase space.

It is quite certain that the CPU is one sold by Intel as “Celeron M ULV”, a low-cost (only 512KB L2 cache instead of 1 or 2 MB) and low-power (ULV) model, the only available with 900MHz besides. This fits all: low-cost, low power, clock frequency.
The suitable chip-set would be one of the 910 series, also a low-cost one.
So, there is is L2 cache. And there are also L1 caches, just to bar further allegations right away.

Look at processor number 353 here:

And the 910 chip set has a GMA 950 integrated graphics!
