If it has a 2mb Cache chip inside, is it not a Dothan, ie. P4-M or am I missing something???
Mister_Tad 13th December 2005, 11:55 Quote
Dothan = P-M != P4-M

edit: Nope, it's pentium 4, mobile

http://www.beblu.net/products/

edit: Ahh no, I gettit now. I was confused because i thought P4-Ms ran at near/full P4 speeds, but to make a P4 "mobile" you have to clock it and it's voltage down. The 915GM will only support a 533bus too.

So it's a full 6xx series P4 processor with 2meg cache, but runs on a 533bus and at reduced voltage at 1.8GHz.

does that mean the P4M is strictly a mobile chip?

...apologises for the offtopic conversation....

The article states there are no dual digital tuners, well this is not strictly true if you live in australia there a few already shipping DVICO FusionHDTV DVB-T Dual and http://www.digitalnow.com.au/product_pages/twindvbt.html but demand is great also you could go for usb options if you want more than one tuner.

Just been discussing it with Wil, and he was previously informed from their site (as you can see from the link I posted, they are using the Pentium 4-M Intel pic) that it was a Pentium 4-M, but just talking to them now they have confirmed that it IS a Pentium M (as in Centrino, as in nothing to do with Pentium 4).

What a nice looking pc :)

...Shame, no 2mb Cache then right??...well would have been a bit of an overkill really tbh... :|

Yea, 2meg Cache Pentium M Dothan. 533MHz FSB, 1.8GHz, Mobile "Centrino" chipset etc.
felix the cat 13th December 2005, 12:27 Quote
ah...so confusing...well, should go and read up about the P4M product I guess...I thought the Dothans were the most expensive of the "mobile" processors??

General crazyness! Updated the article to reflect the fact it's a Pentium M, not a Pentium 4 mobile chip.

It looks great, but is the cost worth it? surely you can put together something very similar for alot less, and if you are handy with a dremel make it look even better...

A fact.


Review:

"For now, why not head over to beblu and check out your options?"

Because, you could wait a month and get a Dual core Pentium/Yonah. Which is gonna kick the A of the P-M in benchmarks.

Come on people, it's a Pentium-M! Bindi, how could it possibly be a 6xx series when:
1. It's considerably smaller than a P4
2. 2MB of cache at the same time as 533MHz FSB
3. 1.8GHz on 533MHz FSB
4. It doesn't have hyper-threading

What would be insteresing is the make and model of the motherboard?

I'd imagine its the aOpen one with all the HD bits onboard

but its bloody pricy

It'll also add price, too.

The benefit of the Yonah coming out is that it should drive the price of this system down to much more reasonable levels. I don't strictly think that a dual core chip is required for this system. There's only one tuner so - at worst - you'll be recording in the background and playing something else back. If there were dual tuners in this system, it would be nice to see a dual core CPU in there.

Don't forget this is a Home Theatre PC, not a desktop workhorse. Of course, a dual core CPU would be nice, but the times where you're going to multitask to such an extent that you require a dual core CPU are going to be limited - at best - in my opinion.

How will it add price?

The Yonah's top model will be 640-USD... The same as the Pentium M 780... Reduce price for sure...

The benefit of having a good-quality dual tuner card is that in no way is a dual-core required for your basic HTPC use, even in the situation above. The only benefit is to get windows off the (very tiny) thread that the card has to use. Even with dual tuning, the cpu uses very little processing power which is stacked to give priority to the show you're watching while the show you're recording goes directly into the RAM and out to physical storage (very, very low requirement that can be done in otherwise dead cpu cycles). An MPEG encoder on-board prevents the need of utilizing the CPU for the actual intensive tasks.

I suspect that Intel will drop the bottom of the line Dothans off the product lineup and fit the remaining Dothans in at a lower price point.

Also, as Brett has pointed out, a good digital tuner will mean that a dual core CPU isn't required, as it will encode/decode the stream without much need for a fast CPU. CPU usage for tuners these days is not a worry, and H.264 decoding is one of the only things I can think of that would require a powerful CPU. Seeing as the UK hasn't even got High-Definition TV yet, H.264 is a long way away from our living rooms.

I do apoligise, Im typing less than Im thinking today. I meant it was LIKE a Pentium 4 6xx series. To make P4s mobile, Intel would have needed to lower the clock speed to reduce the power useage, and then they'd also need to lower the FSB so as people didnt use them in retail chipsets. However P4s do ship with 2meg cache and could be locked to a 533bus (albeit celes) and they could have switched off HT and put it on a 478 socket. Its been far too long since I ever looked at P4Ms, they could still use the old socket which is compatible with the 915 chipset. Intel could have been making money on full spec CPUs that didnt make the 3GHz+ or 800FSB cut and simply cut them down. Makes sense rather than throwing out semi-duff cores.
I was trying to justify what it said on their site (assuming they knew what they used!), although my initial impression was that it was infact a Pentium M.

Hehe...on top of this, HD cards often come with an mpeg decoder instead of encoder (much like digital TV) as it has no use for an encoder on it with digital or HD signal. This is used to faster process the mpeg2 stream with no requirement of CPU... :)

Essentially, good tuners make your CPU necessary for running nothing but the host software and windows (or whatever). Most Linux HTPCs are capable of displaying high-def content off of a ~800mhz processor with no problems. Expect this to change with HDMI rules and such being imposed as of Windows Vista...though that still shouldn't affect the linux market.

Ah! See what you mean now!

Could you ask MrHaz to take a look at that mobo, or has the review model been sent back?

Mister_tad, the mobo looks quite a bit smaller than that AOpen one, as well as having different connectors on the back and the board, and is a different colour. I had a look on DFI's embedded systems website and it may be one of them, I'm not sure.

The board seems similar to:

http://mini-itx.com/store/?c=2#p1630

Which does take a pent m for small formfactor systems

Oh and the proc is further down the page with 2MB

First of all thank you bit-tech for a great review!

There seems to be some confusion with both the motherboard and the processor so let me clarify for you. This system is based on the Intel PENTIUM M 745 1.8GHZ UFCPGA FSB400 2MB CACHE processor. This indeed does have 2mb of cache. The motherboard included in this also supports a FSB of up to 533Mhz. Full specification of the motherboard is available at:

http://www.ibase.com.tw/mb896.htm

I think another thing to note is that this motherboard has a mini-pci card which we currently use for the 108g wireless. This can easily be switched for a second tuner card. Alternatively you can use either one or two USB devices connected to one or two of the four USB ports on the back of the unit.

The only final thing to add would be the availability of a DVI output from a small internal adapter card which gives you the quality of output may want.

Thanks again bit-tech and everyone here. Have a very Merry Xmas!

Susan.

Aha, thanks! In fact, it all makes sense if you look here and here. That mobo is sweeeet though.
