Do the usual benchmarks really provide us with a proper indicator of the worthiness of a HTPC? Is that the performance seen by an average user in real life situations? Such questions often crossed my mind when I looked up the reviews of PCs on various websites. It is almost blasphemous if one were to suggest that the 'Windows Experience Index' is a reflection of what the average user sees. Such a synthetic benchmark might not be a true reflection of the capabilities of the system, but it at least gives an idea to the users as to how much better the system would be compared to the one they currently possess. HTPCs require a different set of performance measurement tests, and we will handle them in the next set of sections. In this, however, we will talk about the general performance metrics in brief.
For readers wanting a lowdown on the core performance aspect (in other words, graphs for various standardized benchmarks) of the motherboard used in this PC, I would suggest reviews from Legion Hardware and Benchmark Reviews. We found nothing in our experiments to dispute their findings. However, one important aspect we would like to cover here is the USB 3.0 performance.
USB 3.0 on the HM55 Chipset
We hooked up OCZ's Enyo 128 GB USB 3.0 external SSD (which has received glowing reviews everywhere with upto 200 MBps read and 190 MBps write speeds) to the front USB 3.0 ports of the Core 100 HT-BD. Contrary to our expectations, we managed to get a maximum of only 93 MBps read and 75 MBps write performance out of the drive. Connecting the same SSD to an USB 2.0 port resulted in a maximum of 33 MBps reads and 29 MBps writes, in line with expectations. We do not get the fabled 10x, but only a 2.7x, improvement over USB 2.0 with the Core 100 HT-BD's USB 3.0 implementation.
A little more analysis revealed that the HM55 chipset does not support PCI-E v2 fully and the bandwidth is limited by the chipset. To get around this limitation, ASRock could have placed a PLX bridge chip on board. We covered this workaround in detail in an earlier piece, but it doesn't make sense for ASRock to implement it in this product. The existing limitation will not be of concern to most users, as SSDs are yet to go mainstream (because of their cost). Most external hard disks with USB 3.0 or eSATA interfaces are inherently limited by the disk-to-buffer transfer rate of around 70 - 90 MBps, and ASRock's USB 3.0 implementation is capable of handling such bandwidth.
Windows Experience Index
A quick glance through the specifications of the system easily reveals the bottleneck affecting the score on the Windows Experience Index. It is none other than Intel's integrated GPU which ends up being the culprit. A screenshot of the Windows Experience Index shows the system chiming in at 5.0. However, we have seen the scores oscillate between 4.4 and 5.2 depending on the graphics driver version, as well as the GPU overclocking status.
Of particular interest is the impressive score received by the processor (6.6), indicating that the performance of this unit would be more than enough for most, if not all, HTPC applications.
DPC Latency Check
Another important criterion for HTPCs is the ability of the system to handle real time streaming of audio and video without dropouts. A handy tool called the DPC Latency Checker helps in analyzing this. This tool was run multiple times in various HTPC scenarios. We did observe red spikes, but disabling the C-states, as well as SpeedStep in the BIOS Advanced CPU configuration helped in alleviating the issue. However, we did not observe any dropouts or playback issues with Blu-Ray or any other media despite the sporadic occurrence of these spikes.
Miscellaneous Performance Indices
Pre-built HTPCs available today are mostly based on the ION chipset, and any comparative evaluation of the benchmark results of this system with ION systems would be grossly unfair for the ION. Both Benchmark Reviews and Legion Hardware compared the Core 100 HT with the ION 330, the 2009 HTPC model from ASRock. Comparing the performance of the Atom to the Core i3 is like comparing apples to oranges, but, for the record, the Core 100 HT system came out better on almost all counts except for the 3D and gaming performance.
On the memory bandwidth side, the Core 100 has more than 2x the performance of the ION 330. CPU performance is around 4 - 5x better. While games appeared to achieve almost similar frame rates on both the Core 100 and the ION 330, 3D performance in applications such as Maya went down by a factor of 2x in favour of the ION 330. Thankfully, applications such as video encoding (a common overnight task for most HTPCs) see a 3.5x performance improvement in the Core 100HT-BD.
In the next section, we will look at the integrated GPU of the Core i3-330M in detail.

Aikouka,Thanks for your insights.
1. Customers should hopefully be able to salvage some stuff from their previous setups (Blu-Ray playback software, keyboards and mice etc.)
2. We didn't do exhaustive testing on the VIA codec. Most of the time, it was disabled since we were using audio over HDMI.
3. The sticker is optional ( It comes as a separate label with the package, but you can choose whether to stick it in the front or not :) )
4. The build quality of the remote is not that great and there are better options out there as you observe.
5. Major drawback of ION is the lower general performance, higher power consumption and absence of HD audio bitstreaming. I think the $200 extra is worth it.

1) It'd definitely be nice to harvest a few extra items from previous builds, but maybe a blurb about the overall cost of the software might be nice. I'm not sure, but it might help people sway toward or against the unit as being their Blu-Ray player, since you can easily just buy a decent separate unit for $100 or so. Another aspect that might sway some users is that the BR software will only truly integrate into WMC (last I checked). TMT3 has a plug-in for MediaPortal, but it isn't true integration (just loads the player and minimizes MP).I guess that all kind of goes with your talk on how it can be a pain to get all of the formats working, which let me tell you... I definitely agree with you on that! I had a point where using my laptop as a HTPC, I could get sound while playing MKVs through WMP, but not with WMC. It was the strangest thing :P.
3) Alright, that's good that the sticker is optional ;). I just wish manufacturers would push to not showing the rest of those connectors. It seems the consumer's desire is to have components that are PCs that don't look like PCs, but not many devices have those connections and if they do, they're typically hidden (except the PS3, but they're out of the way).
5) I think the main point I was trying to drive is that even though the ION is inherently weaker, does it still perform the tasks properly? I mean, you can take the kids to school in a Porsche 911 Turbo, but is it a tad bit overkill compared to a Prius? Do you really think the bitstreaming matters that much? I don't think most people would even be able to tell the difference between a good encode output from a SPU and the bitstream... I know I can't! :)
------------------
I like the articles though... I think the HTPCs are going to become more and more popular as people look for non-standard ways to get content. I've actually gone back to using my server as a quasi-HTPC to help alleviate the stress I was putting on my M1530. It's a little better now that I replaced some of its noisy components :).

" 5. Major drawback of ION is the lower general performance, higher power consumption and absence of HD audio bitstreaming. I think the $200 extra is worth it. "And what about picture quality? HQV v 2.0
The ION does the 23,976 but the Core 100HT - does not.
ganeshts - Thursday, July 22, 2010 - link
Good point, vlad08. The point mentioned was the drawbacks of the ION. Of course, if one wants to give the advantages of ION, they are as you mention.I think the average users just set the display refresh rate to 60 Hz and forget about it.. so the 24fps bug doesn't affect those.
Picture quality.. yes, maybe ION is better. We haven't done benchmarking on that platform yet (and will probably not do because it is a product from last year, and we have more exciting Nvidia stuff coming up) to confirm.

Good point about the software costs. This is really a $900+ machine.The Mac Mini competes well with this machine when you consider:
- It comes loaded with some very nice software
- It's light years ahead, aesthetically
- It beats the AsRock on noise and power consumption
- Most people already have a Blu-ray player and don't want the aggravation of dealing with Blu-ray playback on an HTPC. I rarely use my HTPC (Corel WinDVD) to play Blu-rays because of the hassle factor.

While this seems like a good train of thought, it isn't. The poster above points out he uses pro (which is fine, I do too) but there is no reason why Home Premium, which has media center, wouldn't be used by the majority of users. So, $645 + $91. That's it, for anyone wanting the DVD model. Or, about $736.Your comparison at $900 is based on a comparison with a model featuring a Bluray Drive and Bluray software. This is not valid, because you're now comparing apples to oranges ;) The mac mini doesn't have, won't have, and doesn't support a bluray drive. So, the two aren't the same, at all. There just isn't a comparison.
Whether or not people have a seperate player already, there are lots of people who like the idea of 1 single box doing everything, like DVR, DVD, BD, Media Management, etc.
So, let's say you do a comparison on that front. So, the Mac Mini is $699. DVD only. Yes, it comes with software, but not really a front end for this.. so you download Front Row, which was last updated almost 2 years ago. You then go about hacking it to get your supports you need.
And you add a remote control, because the Mac Mini doesn't come with one. So, even if this remote is "flimsly and crap" you add a remote control that is say $50 (and don't say "iPhone" because then you're adding $300 in expense for a remote for everyone who doesn't have one).
So now the cost of your Mini with a remote is basically the same as this with a copy of Win7HP. Except, oh yeah, even if you get the DVD one of this, your ability to later convert to BD is there. Not at all on the other front. Remote wakeup? Yep. Since neither have tuner slots, both would be using say a network tuner. So, Silicon Dust HDHomeRun for both. So a wash on the cost here, except Front Row can't natively manage those tuners for anything, meanwhile Media center can.
You can buy software to do that on the mac.. now you've spent more money.
The Mac Mini is a good unit as a desktop. But for an HTPC, you spend a lot of money for almost no bang. You can get an ION based unit at about $350 that is DVD based that gives you the exact same features.... plus LPCM for your MKVs that the Mini doesn't do worth a damn.
Nothing against the Mac, but not every purpose works out for it. This just isn't one where you say "wow is that a great solution for a Mac". And AppleTV is a laughable product that should die a slow death.

One reason that ASU *cough* I mean ASRock is always the first to put these out is probably that all of their SFF machines use the exact same case, nearly the same packaging, and mostly the same pack-in material.They've used this exact same case all the way back to their first Atom machines. Their ION machines also used this case, as did their bluray machines.
Now that they've introduced some CULV machines, surprise, same case again.

True.And why is it narrow and tall? Why can't they put this in a DVD-sized case with the industry standard width? The front should look just as clean as a nice DVD player, with the front ports, buttons and maybe even the drive behind a fold-down door.

"Unfortunately, there is no single unified interface (from XBMC or MediaPortal or any other similar program) which could successfully play back all the files from within. "Cant SageTV play back all the tested formats?

I wish I seen this coming last month Just about finished building one ECS itx mobo and i core 3 530 in jetway 101 case and mines going to end up at about grand after software and tuners. And as far as tuners go for the asrock get a USB or homerun Ethernet.
