General Performance Metrics
We are not going to compare our build with full-blown desktop solutions. Instead, we will see how the unit stacks up to some of the low power offerings that have graced our labs. Some of the benchmarks have been run for the first time, and hence, not all benchmarks are available for all units. In addition, we are only presenting benchmark results for our build under Windows 8.
Windows Performance Index
This metric is often considered meaningless, but we feel it serves as an indicator of what could be the bottleneck in a system. On Windows 8, systems can score up to 9.9 on this metric, compared to 7.9 on Windows 7.
Given that we have equipped the system with SSDs and the RAM runs at the prescribed maximum of 1600 MHz, it is no surprise that the HD 4000 GPU is responsible for a score of 4.7 for the system.
Futuremark Benchmarks
Miscellaneous Benchmarks
Starting with this review, we are going to utilize Graysky's x264 Benchmark v5.0 for testing out x264 encoding performance. Instead of just presenting benchmarks for our build alone, we took the opportunity to run the benchmark on two HTPC units we reviewed earlier.
There are no surprises in the benchmarks, with the CPU performance befitting a 55W TDP unit. The absence of four physical cores does hurt it against the i7-based units in the above graphs (and would have showed in the x264 benchmark too, if we had run it on a i7-based system). However, this is not a concern for most HTPC workloads.

No real useful advantages. But, it's $40. Oh yeah, and new task manager, new file copy dialog, storage spaces, data deduplication, WAY less naggy updates, fast boot (way faster than 7), extra dimension in your start menu for more stuff.Nothing at all. Reply

My Win 7 HTPC works just fine with my network streaming Silcon Dust dual tuner.I rebuilt by gaming PC with Windows 8 and after a week I couldn't take it anymore, re-installed Win7-64bit.
-Stupid UI
-Dumbed down for Grandpa and Grandma
- Stupid colors in office (aka none per se)
- COD4 and older games don't work.
Win7 has none of these issues, so if the only benefit I get is a netflix app that uses a tad less power, and a crappy UI forget it. Reply

"Fast boot" is fast because it changes normal shutdown to "hibernate".If you force the OS to do a proper reboot, there's no improvement over 7. Reply

Actually you can do a lot more with Linux than just surf YT. Check out MythTV. It is a VERY capable PVR/HTPC suite.In my opinion, much better than any product available for windows, and free too. Reply

Is there any way we could get a look at how you have configured the various settings for the LAV filters and madVR for our own personal testing? Replygeekfool - Sunday, January 20, 2013 - link
That would indeed be helpful, because teh performance of the scaling algorithms differs a lot. lanczos3 is more demanding than bicubic, and jinc3 (not to mention higher variants) is even slower (sadly, it seems to be the best upscaling method). On top of that, there is the highly beneficial anti-ringing (AR) feture that further increases the performance requirements.For illustration, jinc3 upscaling with AR) reached to 40ms processing time per frame (1920×1080 target resolution) in some cases on A8-3850 (1600 MHz RAM). With that, it starts to stutter in panning scenes even with 24 fps content. Lanczos4 AR is fine.
It would be interesting to see which scaling methods are actually viable on HD 4000... Reply

Yes, the scaling algorithms affect the performance a lot.That is why I mentioned that we used the default settings: Bicubic with sharpness 75 for chroma (no anti-ringing filter), Lanczos 3-tap for image upscaling / Catmull-Rom for image downscaling (no anti-ringing filter or linear light scaling),
We will look at other scaling algorithms and their performance on the HD 4000 / GT 640 / AMD 7750 in the third part of the HTPC series.
Also, a note that if you are using HD 4000 (or any other Intel HD Graphics), I would strongly suggest looking at DXVA Scaling. Users might be surprised at the quality delivered without taxing the GPU too much. Reply

in regards to the refresh rate issue, which i am not too familiar with, have you tried modifying the EDID in the registry to help fix it?link: http://www.monitortests.com/forum/Thread-Custom-Re... Reply

How do the final capabilities of this compare to the plethora of android mini PCs floating around? Things like the MK802, G-Box etc seem to have a beta version of XBMC with network storage support now. Or if you want to move upscale a bit googleTV, Roku etc?Other than the fun of putting it together is there an upside? My napkin math puts this build north of $600. That is a lot of delta to make up.
