Core 2 Duo E7200
Intel’s Core 2 Duo processor was launched in late summer of 2006, and it arrived with a bang. All of a sudden, AMD’s Athlon 64 X2 processors were outclassed by a product that delivered better performance while simultaneously requiring less energy. Launched at a 2.66 GHz clock speed (2.93 GHz for the unaffordable Extreme edition), it held its superior standing for more than two years.
The first update was a bus speed bump that took the processors from FSB1066 to FSB1333 in the summer of 2007 with the launch of the P35 platform and slightly modified processors. The second modification was FSB1600 speed in the high end and shrinking the process from 65 nm to 45 nm. All of the Core 2 Duo E7000, E8000 processors and Core 2 Quad Q8000 and Q9000 are based on the 45 nm Wolfdale cores. Yorkfield, which is the core name for the quad core, utilizes two Wolfdale die.
Core 2 Duo E7000
Over time, Wolfdale received some improvements, the latest being the introduction of the M0 stepping, which continues to reduce processor power in idle states when compared to the L steppings. We looked around for a reasonable processor that utilized the latest stepping and we found the Core 2 Duo E7200, which utilizes only 3 MB L2 cache instead of 6 MB cache. Undoubtedly, the reduced L2 cache capacity represents another power saving opportunity, of which we wanted to take advantage.
The E7000-series currently consists of only two models: the E7300 at 2.66 GHz and the E7200 at 2.53 GHz. Both are based on the Wolfdale core, but again have only 3 MB L2 cache and a reduced front side bus speed of FSB1066—this is in contrast to the FSB1333 used for all Core 2 Duo E8000 models (which have 6 MB L2 cache). The E7000 series does not support virtualization technology (VT) nor Trusted Execution technology (TXT)—this isn’t an issue for our purposes, since both are insignificant for mainstream desktop users. A smaller L2 cache capacity together with relaxed clock speeds makes this processor an excellent choice for a high efficiency computer as you’ll see in the benchmark section. Despite being rated at the default TDP of 65 W for desktop processors, the Core 2 Duo E7200 stays pretty far away from that limit.
Nice article. I'd like to see the team now take this budget system and tweak it into a gaming machine. New power supply, overclock it, 4870 GPU and see what this budget platform can do when pushed. Compare it to a stock clock E8600, X48 motherboard, 8 GB of RAM and a 4870. Although low power systems may be the rage right now, when i turn a 1,500w electric heater on in the bathroom when i take a shower in the morning it's not a huge concern for me if one mobo is 31w at idle and the other is 38w.
You don't leave your heater on 24/7 in the bathroom - 8 watts here 8 watts there, it adds up (if you keep your PC on all the time)
Or you can get a 4X50E with a 740g or 780g, that is cheaper and equal energy efficient and has all the futures like HDMI, 3D performance.

As far as turning this machine into a mean, green gaming machine, I would suggest an e2140-bsel pin modded to 1333 fsb, a hitachi 500GB sataII drive-4w/8.3 idle/max, and a hd 4670 videocard-no external power plug required. This would make a very potent rig. I know this because that's what I have on the foxconn board used in this article One last thing, with case, p/w supply and 2Gb ram the total cost (including shipping) was less than $300.
Sounds like a nice build!
Yes, from the silentpcreview article, it seems like 740g or 780g could be a better choice.

Ya most people would do just fine with an amd system. But TOM's got new free computers, car's, spaceships from INTEL and NVIDA so nowadays tom's are a EPIC bias.
I don't get it? These mobo/cpu combos are so lame. The atom on a desktop mobo is also very lame. How far should people go to save a few watts of power. These machines are in my opinion totally useless.
Why not just buy a laptop? I have a Dell M1330 with Nvidia card graphics fast dual core processor that easily runs Vista w/Aero, runs Photoshop CS3 I use to edit field RAW photography, and plays HalfLife 2 at full res with ease. It draws around 30W at full load and 20W in idle, and has HDMI out for watching movies, not to mention how small it is. It dual boots both Vista/WinXP.
Now that we have desktop systems that approach laptop-level power requirements, I would say that in a year that we should have some really good choices on the market for low-power-consumption desktops.
That is... if the world still exists as we know it in a year...
warezme you are a retard.
Where I work there are currently 120 desktops between 4 levels. Each desktop is on 24/7. If i can save 10 watts on each of those desktops im saving thousands of dollars per year. Get it now? Just because you are a gaming scrub with no clue doesnt mean that all technology should appeal to you.
Skythra your apparently nothing but an A hole of major proportions and if you honestly thing your users will get by on the measly performance offered by these equally tarded setups as you are, to save "10 wats" than go for it because it sounds like your deserve them....
Calm down folks. Warezme, there are people interested in these setups, they just need to run internets and word. While the components are indeed weak it is not lame to write about them, esp for business perspective.
Skythra, no need to call someone retard for expressing an opinion which I agree with by the way. These desktops are really nerfed and a laptop would fit nicely as prices have dropped a lot.
Carry on now.
Warezme:
Get serious. This machine has ample power for the standard office productivity applications, which probably represents 90% of the use of computers in the world, including in the corporate sector. The difference between these builds and a stacked $2000 machine is almost totally invisible to such users. Indeed, the only people that would really notice the difference are the people writing check to the utility companies.
I like AMD but I am no AMD fan boy. The only AMD X2 chips that come close to E7200 is 6000+ and 6400+ and they use a lot more power. In addition, if for some reason, I need more power than 2.53 GHz I can just OC to 3.0 GHz without voltage increase. Find an X2 that can achieve 3.8 GHz with reasonable voltage.
At work I had a choice between an HP laptop or desktop, I took the laptop for work at home, but If i did not go on road, a g31/e7200 setup would demolish my t7300 laptop with 2gig ram on a 800 bus with ddr2 667.
I dont play a single game on this laptop but i do watch a movie here and there...and its fine...so the g31 would be more than enough....
I just have one more comment regarding recent toms articles....how is a 1,500$ system a budget system...I dont have the money to buy that when i'm gaming once in a blue moon.
I built a system for about 400$ and comes close to some of these things....an e2160 chip at 2.6ghz, 2 gig ram, asus p35 board, and asus 8600gt, an 80g sata drive for the os and an older sata 200g for some tunes and pics....and i bought a cm 690 case with cm5500 extreme power ps....the only thing in their i wish i could change at the mobo(settings dont allow for good overclock) and the power supply is loud...but that system is close to what i can afford....spending 1500$ to me is not budget, not when your putting a quad core and other stuff, a budget system should be that, on a budget, shopping for deals....etc...oh and if ya wanna save power...shut the mofo down....if your woried on how much a small system will cost on electricity you should have bought the system....just like the idiots that buy a dodge ram v8 and have never put more than a few pieces of wood in it and cant afford the 150$ gas bill each week.....
GMA 3100 is NOT based on GMA 3000 - this is totally different. It is based on the older GMA 950 (pretty much 100% identical in fact).
I would like to see a amd comparison, such as the AMD Athlon 4850e 2.3GHz paired with a FoxConn A7GM-S. This is a $135 pairing as opposed to the Intel reviewed which is $175.
Warezme, i don't think you have a very good understanding of how some people use cmoputers. Not everyone uses their comps for gaming and not everyone can use a laptop to meet their needs. I personally run a X2 4450e on a 780g chipset to house my raid array. This setup runs quieter, cooler and draws less power than my previous P4 setup.
Just because you cannot see a use for this technology does not mean the rest of the world cannot. Some of us care about how much power we use.
HTPC
Why not just get a laptop??? You would also save power with its LCD screen versus a separate monitor.
Isn't this what many people requiring a non-gaming machine are doing these days??
