AMD Athlon 64 vs. Intel Atom

by

AMD and Intel both use 300 mm wafer disks in their production lines. At 77 mm², the Athlon 64 2000+ is more than three times larger than the Atom at 24 mm², which means Intel can produce and sell three times as many CPUs. in fact, Intel can get about 2,500 processors per wafer, while AMD can get only about 800.

Intel vs. AMD
CPU Atom Athlon 64
Power 4 Watts 8 Watts
Transistors 47 mm 122 mm
Size 24.18 mm² 77.2 mm²
Core Voltage 1.088 V 0.900 V

The Athlon 64 2000+ has 122 million transistors, and the Atom 230 only 47 million. If you look at the relationship between the number of transistors and energy consumption, a single Athlon 64 transistor uses less energy than an Atom transistor, even though Intel produces it using a 45 nm process while AMD relies on 65 nm manufacturing.

The Athlon 64 2000+ (OPN ADF2000IAV4DRE) runs on the Lima core at stepping G0. The HyperTransport frequency is 1000 MHz. This, of course, saves additional energy versus AMD’s more modern Phenom X3 and X4 CPUs. The Athlon 64 is on the same level as the Atom in terms of multimedia extensions, and the 64-bit instruction set has also been implemented.

yay, good for amd..

now if they can get a tiny mobo out and sort out those other issues, they mght be able to make the lead even greater.

good for amd!

Nice article... But where are the CPU usage charts of HD and DVD playback on the Atom...?? :lol:

There surely would a case for the MB BIOS to support a dynamic overclock just to pull the Athlon 2000+ into the bottom range for HD playback??

Because these processors aren't aimed at performance junkies. The big space right now is enterprise users looking for low power consumption for thin clients and data warehouses, where temperature and energy consumption are limiting factors over the speed at which bankers can play quake.

Jetway has announced a mini-ITX format mobo using the 780G, its code NC81 LF - see http://www.jetway.com.tw/jw/ipcboa [...] me=NC81-LF

unruled :
think netbooks (eeepc/acer one/msi wind)



exactly !

Fit that desktop setup inside a netbook case then I will be impressed.

Ps. Not a comment against the Athlon, but come on apples to something in the fruit family would be good. I'm sure my Core2 would be very power efficient at ~600mhz.

Were is the power readings for the system taken from?? Before of after the PSU.

This needs to be used in a netbook.

Raon apparently have a 7" umpc/netbook using the old 690G chipset:
http://www.umpcportal.com/2008/08/ [...] 9-version/

i personally think they missed the boat because they should absolutely be using the 780G chipset.

MSI had a small board too so you could compared the 2 of them on the same board size: http://global.msi.eu/index.php?fun [...] cat_no=388

Intel deliberately cripples the capabilities of Atom motherboards to make sure Atom doesn't sabotage sales of Celeron CPUs. If I remember correctly, the following limits are imposed on Atom motherboard makers:

No PCIe graphics slot allowed
Only 1 Ram slot allowed
No more than 2 SATA Ports allowed
No Gigabit Lan allowed
Only 1 PCI slot allowed.

I own an Intel Atom board, which I use as a Network file server and bittorrent downloading machine. It draws about 40 watts.

Tell me please the secret, how are you guys doing so nice screenshots of the BIOS? That is definitely not a photo, nor an analog grab over some output, but I'm not aware of a way to grab such nice picture over digital-something (DVI, HDMI ... ?).

Well... J&W actually already have a miniITX motherboard with 780G Chipset, should be more comparable to the atom platform tested.

Dual monitors? Blu Ray? Vista?....who buys Atom or Athlon? There's three things that will drive this low power market, price, price and price. The ability to produce low cost, reasonable performance and small form factor desktop and mobile PC systems is where the game is, not how fast you can rip this or render that. Sadly, most poeple miss the point of this - you want performance, spend the money to get it, if you want a low cost PC that can do email and internet, and in netbooks case, give extraordinary battery life, be prepared to sacrifice performance to get a basic PC. Low cost and energy efficiency is the new mantra for new markets all over the world today.

I don't understand...
I can play DVD with a pentium II. How can CPU consumption went so high with an Athlon 64@1G?

Also, for bluray, in my Athlon X2 @2.5G it hardly passes 10%(with hardware acceleration of course.) multiply it by 5 should be an overestimate of the usage, yet it only gives you 50%...

Are you sure it's not an OS problem?

Thanks for the review. I'am have been playing with low power systems since 2003, build my own server based on Geode G1 and PC/104 system 300 MHz, running as web/email server for years with Suse linux and X server. It consumes 8W in power and was running 24/7 withou any problems. Imagine, that it can be done. No need for 4 cores 1000 GHz and 2000 GB RAM and noisy fan!

Recently I replaced it with 1 GHz VIA C7/ 1GB RAM, 10W, (lex neo system)which is running OpenSuse 10.3. It is not a high performance system, however it runs very smoothly.

Do you consider to compare this kind of low power system with the Atom and Athlon systems? I'am suprised, that the power consumption of the described systems is so high compared to their efficiency.

That 0.95W figure for the 780G power consumption is for Idle power, not TDP surely...?

But where can you buy these low power AMD chips?
I don't see anyone selling them.
I see lots of Atom boards with chips.
An interesting article but practically not very useful until someone starts shipping the chips

Great subsitute for thin clients because it's not dependent on a server. Could office work all day long on an Athlon 64 2000 rig with and 780G mobo. Great machine for anyone only doing office and internet.AMD please [/b]get an OEM to sell machines with a combination of very low power consumption like that.
