Puget Systems Echo: Intel and AMD Showdown at 65 Wattsby Dustin Sklavos on March 21, 2012 2:35 AM EST

Just about anyone can put together a solid computer using a decent midtower and the right parts. What we don't see as often is just how fast a computer can be assembled in a small form factor. More and more, too, the term "fast" isn't an all-encompassing one; as the GPU becomes increasingly important, the definition gets foggier and foggier. Today, all of these considerations collide as we test two top end configurations from Puget Systems against each other.
On the outside it looks we have two systems assembled in Antec's ISK-110 enclosure, but on the inside, we have a showdown between Intel and AMD's best and brightest at 65 watts. The more cynical (and admittedly informed) reader may already have an idea of where this is going, but there are definitely some surprises in store.
The Antec ISK-110 is a mini-ITX enclosure with exactly enough space for the motherboard, CPU, memory, and two 2.5" drives located on the opposite side of the chassis, underneath the motherboard tray. There's no space inside for a power supply, and indeed each enclosure comes with the necessary tools to mount it to a monitor's VESA mount, effectively hiding the entire system. As a result, the ISK-110 employs an 80-watt external power supply—good for saving space, bad for driving powerful hardware. Puget Systems faced a very real limit as to how much power could be crammed inside this chassis, but we felt like it would be a good opportunity to see just how powerful a system could be built in it...from both AMD and Intel.
In an effort to keep things fair, Puget Systems tried to use as many of the same components as they possibly could between the two builds. In practice things didn't quite work out that way, as you'll see later.
In the Blue Corner...
Expectations for our Intel-based system are set appropriately; Intel's been leading AMD in terms of CPU performance-per-watt for quite some time now and there's no reason to expect anything to change here, especially with the bulk of the Llano desktop chips sporting 100W TDPs that remove them from contention for this build. Here's what we're testing in the Intel configuration:

First of all, Puget Systems opted to equip their Intel version of the Echo I (the Echo II line can handle higher TDPs and includes an optical drive, but in a slightly bigger chassis) with the fastest CPU that Intel offers at a 65W TDP: the Core i7-2600S. The i7-2600S is able to turbo up to as fast as the regular 95W i7-2600 can on three cores, two cores, or even just one core, but on all four it peaks at 2.9GHz. For all intents and purposes, that's not a huge hit in exchange for being able to fit inside the power envelope this enclosure's power supply requires.
That's a lot of heatsink for a small chassis!
Where things do get a little bit dicier with the i7-2600S is the integrated graphics processor: the i7-2600S uses Intel's cut-down HD 2000 graphics that sports half the shader cores the HD 3000 does. This is actually a small change of pace for us; the HD 2000 is actually fairly rarefied in review systems we test, as on the notebook side [nearly—mobile Celeron and Pentium have lesser GPUs] every CPU's IGP has all twelve shaders, while the desktops we test almost never run the IGP.
Instead of full length DIMMs, the ASUS P8H67-I Deluxe uses a pair of SO-DIMM slots that admittedly prevent our comparison from being completely fair. Keeping with maximizing these configurations, Puget Systems filled both slots with 8GB DDR3-1333 SO-DIMMs from Patriot. The PCIe x16 slot is left unoccupied (and there's really no room for a GPU in this chassis), while the board's wireless duties are handled by an Atheros AR9285 controller.
Finally, storage is handled by an Intel 520 series SSD with a 240GB capacity as the system drive, while a slow 1TB Western Digital Scorpio Blue running at just 5,200 RPM handles mass storage. You can actually configure the system with a 750GB Scorpio Black for a bit less money, and that drive runs at the full 7,200 RPM, making it potentially a more ideal choice unless you absolutely must have the extra space.

BSMonitor - Wednesday, March 21, 2012 - linkWhy wouldn't they go down the road of using a mobile CPU for these types of systems?? They are already using customized motherboards. Seems like there are plenty of Core i7's with HD3000 in the $310 CPU range.
frozentundra123456 - Wednesday, March 21, 2012 - linkSounds like a great idea to me. A mobile chip with the HD3000 might even be a better balanced Intel system than the one they tested which if too strongly biased toward the CPU.
silverblue - Thursday, March 22, 2012 - linkA mobile CPU would make plenty of sense here on both sides, along with SO-DIMMs for the AMD setup.
Death666Angel - Wednesday, March 21, 2012 - linkConsidering the price differences and the different markets the AMD APU and Intel CPU play at, these results are expected. It would have been nice to see the A8 65W APU with its superior IGP and more cores and higher clock. But that thing is seriously hard to get.
I settled for a A6-3500 in my HTPC. It was much cheaper than any Intel solution at the time, the IGP is more important to me than more CPU power and undervolted it uses about as much juice as any Intel CPU. And this way I can support AMD some and increase competition (I use Intel in my desktop machine and my Laptops).
krumme - Wednesday, March 21, 2012 - linkFor me Dustin just writes the best review currently on the web, far from the usual we need 7870 oc to get the job done, that doesnt reflect normal user behavior.
This review, as the others from Dustin, is usufull for recommending solutions for family and friends,
except the minor detail i dont think they would care about the next wonder from AMD or Intel the same way we do :)
Interesting products. Then add we got some surprising power numbers.
All delivered in delightfull english
Jamahl - Wednesday, March 21, 2012 - linkThanks for this review, I've been looking at the A6-3500 as a possible build (as a reseller) and I'm pretty happy with the results here - especially the power draw ones.
Jamahl - Wednesday, March 21, 2012 - linkWhat exactly were you running while testing power consumption btw?
Dustin Sklavos - Thursday, March 22, 2012 - linkAIDA64's stress test, hitting the CPU and GPU simultaneously.
Luscious - Wednesday, March 21, 2012 - linkI'm really REALLY surprised why the writer didn't push Puget for not using the i5-2405S in such a build - lack of knowledge?
The 2405S is also a 65W part, slightly slower at 2.5GHz, only has 6MB Cache, but it does dish up HD3000 graphics. If I were building a mini-ITX system for a HTPC, this would be the CPU I would choose.
If 1080p gaming was my concern, I wouldn't even look at a mini-ITX enclosure...
Dustin Sklavos - Thursday, March 22, 2012 - linkOur thought process working with Puget was to just crank out the most powerful systems we could on the AMD and Intel sides. What's interesting, I think, and I touched on this a little in the review...you can't really say anything's just "the most powerful" anymore, and the review proves it. As a result, the comparison did suffer a little, but I'd like to think the information gleaned was useful nonetheless.
