miniREVIEW | Silverthorne: The Intel® Atom™ processor

Introduction:



Silverthorne_right_resize2.jpg



Silverthorne

On March 2, 2008, Intel announced the new processor (code-named Silverthorne) to be used in ultra-mobile PCs/Mobile Internet Devices (MIDs) which will supersede Intel A100. The processor is a 47 million transistor, 25 mm2, sub-3W IA processor which allows ~2500 chips to fit on a single 300 mm diameter wafer, allowing for extremely economical production.

A 1.8 GHz Atom processor's single thread performance is equivalent to its predecessor Intel A100 but should outperform it on applications that can leverage simultaneous multithreading, SSE3, and EM64T x64 extensions. It has a 0.6W to 2.5 TDP rating that can dip down to .01W when idle but that does not include the power consumption of the chipset. It features a 2-issue simultaneous multithreading, 16 stage in-order pipeline with 32KB iL1 and 24KB dL1 caches, integer and floating point execution units, x86 front end, a 512KB L2 cache and a 533MT/s front-side bus. The design is manufactured in 9M 45nm High-k metal-gate CMOS and housed in a 441-ball µFCBGA package."

In short: A 45nm processor, 47 million transistors, 26mm² in area, 2.5W TDP and a whole lotta power savings!




Package:

After a long wait, i finally got the Atom from Delta Peripherals

[BREAK=Board Layout]

Layout:

Pretty small but powerful. Something amazing is that the cpu is passively cooled while the 945 Chipset has been given active cooling. Not something you generally come across.

(that's the only solid state capacitor onboard.)

20-pin main power connector instead of the 24-pin

One IDE and 2 sata connectors capable of connecting upto 4 Drives

The southbridge

2 fan headers, one being used by the chipset.

(but it doesn't seem like the cpu even needs one)

Expansion options are very limited with one PCI slot

PCI express, would be "asking for too much", although it can be of great use for HTPC's

[BREAK=Bios and Hardware]

Bios & Hardware:

Its same as what you generally expect from an Intel board. The only disadvantage, not being able to overclock from BIOS.







Hardware Setup:

  • Intel Atom (1.6GHz)+ D945GCLF
  • 1Gb Corsair Value Select @ 667 Mhz
  • 80 Gb Seagate HDD
  • Dell SP2208WFP (1680x1050 via analog cable) *cant help it, I don't have a smaller monitor..:ashamed:
  • LG IDE DVD-RW Drive


  • Generic Cabinet and PSU

Windows XP with SP2

Installing:

Right from the time it says copying files, till its ready for use.

Time taken for Installation: 25m, 15s

Windows installed with no issues. Drivers had to be installed, the generic ones don't work well.

The GPU was running the graphic interface at 800x600 without the driver being installed. After installation it could manage 1680x1050.

No lag is seen during normal usage, works well with most applications running(office, messengers, A/V, Firefox and media players).

[BREAK=Tests]

Tests

I wished I had a system to compare this with, nevertheless i tried to get some results to give you some idea of its performance.

Super-Pi -1M

1m,33.484s



Stress Test and Temps:

43C was the max it would touch.



Cinebench R10

(default settings)



Open GL standard Test:273

Single CPU Render Test:547

Multiple GPU Render Test:835

Unigraphics NX4 :p

Well believe it or not, this CAD/CAM software runs smooth as silk.

I'm not saying that it can do all possible stuff, but beginners modelling can be done pretty easily.



Creating the model was a cake walk, but rendering with textures/matetials using RayTraced/FFA took 18.2sec (which is quite bearable as rendering is not what you would do all the time).

[BREAK=GPU]

GPU

The CPU seems to have done whats it says, but a performance drop is seen due to the 945 chipset. The IGP does not perform in line with the CPU.

Its quite primitive, from the standpoint of the CPU

GTA San Andreas

Just for the fun of it, At first I tried running it at 1680x1050

It loaded the game, but really sucked. The game was moving frame by frame.

I then tried it at resulotions 800x600 and 640x480.

It wasn't all that great, but playable. The image quality was pathetic.

800x600|640x480
Looking at the GPU performance i gave up the idea of trying Need For Speed Most Wanted and running 1080p videos.:ashamed:

[BREAK=Vista?]

Now comes the interesting question.

Will it run Windows Vista with all its bells and whistles?

Installing Windows Vista Ultimate

Right from the time it says copying files, till its ready for use.

Time taken for Installation: ~26mins

Installation+Initial Benchmarking Tests: 37mins

Now that its installed, the drivers are required before conducting the next benchmark test.

Before installing the drivers, I got a lowest rating of 2.3.

here's what I get now:

rating.jpg


Its quite obvious that the GPU is not meant for any kind of gaming.

But is it capable of eye-candy?

Atleast the sidebar and Windows flip work smoothly. (at 1680x1050:hap2:)

So as long as you stick to using it for office work, some music, a couple of videos and internet. It should work great. (I don't recommend Vista though)

[BREAK=Conclusion]



Knowing that you can get a Celeron+nForce610 combo for almost the same rate, its difficult to convince people to buy this, as it doesnt have the advantage of the nvidia chipset. But this combo comes in a total different category. Its main purpose being compact, having almost no moving parts, and low power consumption.

As I mentioned the GPU/CHIPSET is pathetic, but it gives the option of other desktop features, like having SATA drives and other stuff. The 945 Chipset itself consumes more power than the processor, so until a better chipset comes out, its application in laptops will be the only best option. As for desktops its limited to NAS Drives, Car PC's, Office PC's.

The most suited Operating system would be Windows XP, which works flawlessly(as long as you dont play the new 3D games and watch HD videos).

As for linux, I'd say throw any distro, it will run just fine.

Pro's

  • Compact.
  • Efficient and low power consumption.
  • Price (Rs.3350/-@ Deltapage.com)
  • Almost no moving parts (by using flash disks and passive cooling)
Con's
  • 945 Chipset
  • A PCI-e Slot could make a great HTPC
  • Poor 3D performance
Other Thought's:

RAID and Gigabit LAN would be an added bonus.

Well this was my first review, please throw in your comments.. whatever it may be.!:)

-regards
