Something like the ASRock M8 can be difficult to benchmark. Ultimately what benchmark results we get will essentially be dependent on the hardware a user adds in, and what we have placed in the build will be different to what any other user will do. Also, there is almost no cross correlation from previous reviews for heat/noise, as Dustin was our case reviewer and I have no other starting point. Nonetheless, I have repeated the majority of my usual benchmarks in the system, as well as tried to copy Dustin’s benchmark routine for comparison points. Our test setup is as follows:

Many thanks to...
We must thank the following companies for kindly providing hardware for our test bed:
Thank you to ASRock for providing the M8 review sample.
Thank you to Intel for providing the i7-4765T CPU used in this review.
Thank you to G.Skill for providing the Ripjaws SO-DIMM 1866 C9 memory kit for this review.
A note on the G.Skill memory kit – up until the opportunity to review the ASRock M8, I was under the impression that SO-DIMM memory kits, for the most part, were set at DDR3-1600 CAS 9 at the high end. Around the same time, G.Skill launched their Ripjaws SO-DIMM memory range, featuring 8GB modules at speeds higher than 1600 C9. These were at 1866 C10 (Performance Index rise from 178 to 187), and the two 2x8 GB modules are currently on sale for $160.
Power Consumption
Power Consumption | |
Long Idle | 55 W |
Idle | 44 W |
OCCT | 83 W |
Metro | 242 W |
Despite using a 200W TDP graphics card and a 35W TDP CPU, the total system draw under Metro is 242W – more than adequate for the 450W bronze power supply used. The limiting factor it would seem is temperatures, at which point the system would not be able to exhaust enough heat.
Temperatures
Temperatures | ||
CPU | GPU | |
Idle | 35 ºC | 35 ºC |
OCCT CPU Load | 60 ºC | 36 ºC |
Furmark | 42 ºC | 76 ºC |
While under load, it was clear when the GPU was being stressed from the top of the case – it became warm to touch, almost uncomfortable if held for a long time. Although I would be satisfied with these temperatures in the long term – no game stresses the system as much as Furmark.
Windows 7 POST Time
Different motherboards have different POST sequences before an operating system is initialized. A lot of this is dependent on the board itself, and POST boot time is determined by the controllers on board (and the sequence of how those extras are organized). As part of our testing, we are now going to look at the POST Boot Time - this is the time from pressing the ON button on the computer to when Windows 7 starts loading. (We discount Windows loading as it is highly variable given Windows specific features.) These results are subject to human error, so please allow +/- 1 second in these results.
At 13 seconds the M8 is not a slouch, but not the speediest boot up sequence we have had for Z87. There's still some margin to go for a sub 10-second POST.
Rightmark Audio Analyzer 6.2.5
In part due to reader requests, we are pleased to include Rightmark Audio Analyzer results in our benchmark suite. The premise behind Rightmark:AA is to test the input and output of the audio system to determine noise levels, range, harmonic distortion, stereo crosstalk and so forth. Rightmark:AA should indicate how well the sound system is built and isolated from electrical interference (either internally or externally). For this test we connect the Line Out to the Line In using a short six inch 3.5mm to 3.5mm high-quality jack, turn the OS speaker volume to 100%, and run the Rightmark default test suite at 192 kHz, 24-bit. The OS is tuned to 192 kHz/24-bit input and output, and the Line-In volume is adjusted until we have the best RMAA value in the mini-pretest. We look specifically at the Dynamic Range of the audio codec used on board, as well as the Total Harmonic Distortion + Noise.
Despite using a Creative audio codec on the motherboard, the final results are bottom of our small pile - dynamic range seems alright enough, but THD+N needs a rethink.
USB Backup
For this benchmark, we run CrystalDiskMark to determine the ideal sequential read and write speeds for the USB port using our 240 GB OCZ Vertex3 SSD with a SATA 6 Gbps to USB 3.0 converter. Then we transfer a set size of files from the SSD to the USB drive using DiskBench, which monitors the time taken to transfer. The files transferred are a 1.52 GB set of 2867 files across 320 folders – 95% of these files are small typical website files, and the rest (90% of the size) are the videos used in the WinRAR test. In an update to pre-Z87 testing, we also run MaxCPU to load up one of the threads during the test which improves general performance up to 15% by causing all the internal pathways to run at full speed.
If anything our USB transfer speeds are pretty much in the gutter - USB 2.0 had issues in peak throughput, leading to the worst XFast timing we have seen, and basic USB 3.0 performance is likewise pretty poor.
DPC Latency
Deferred Procedure Call latency is a way in which Windows handles interrupt servicing. In order to wait for a processor to acknowledge the request, the system will queue all interrupt requests by priority. Critical interrupts will be handled as soon as possible, whereas lesser priority requests, such as audio, will be further down the line. So if the audio device requires data, it will have to wait until the request is processed before the buffer is filled. If the device drivers of higher priority components in a system are poorly implemented, this can cause delays in request scheduling and process time, resulting in an empty audio buffer – this leads to characteristic audible pauses, pops and clicks. Having a bigger buffer and correctly implemented system drivers obviously helps in this regard. The DPC latency checker measures how much time is processing DPCs from driver invocation – the lower the value will result in better audio transfer at smaller buffer sizes. Results are measured in microseconds and taken as the peak latency while cycling through a series of short HD videos - under 500 microseconds usually gets the green light, but the lower the better.
ASRock does really well in our DPC Latency test, being the best Z87 motherboard we have tested so far. It magically comes under the 145-150 microsecond barrier we had been seeing up until this point.

Is the optical drive really DVD only (not Bluray?) If so that seems exactly wrong to me. I'd rather have either no optical drive at all and save the ~$70, or have one that can play Blurays.Death666Angel - Monday, January 6, 2014 - link
German website tweakpc.de says it is blu ray. But I have no idea how you get $70 for a slim DVD ODD. They retail for 20€ here.fuhgetaboutit - Friday, January 3, 2014 - link
Minor nit - article should use one space after a period, not two.http://channel9.msdn.com/Blogs/TheChannel9Team/Bil...

Personal preference, was always taught to use two from the early days and it seems unnatural to my eyes to see only one. There are reams of articles, blogs and even societies and groups for each, just as there are the serial comma (which again I was taught to use, and leaving it out feels wrong), or that companies are plural entities, not singular. I always used double spacing for publishing to scientific journals, never heard a peep from their stylists.Johnmcl7 - Saturday, January 4, 2014 - link
I've always been taught to use two spaces after a full stop, one after a comma and still do partially because it's what I'm used to but I think it looks better as well.John

Why did they bother using the Z87 chipset? With that minimal power deliver and recommendation to avoid overclocking, it would have been cheaper to use the H87 chipset.theNiZer - Friday, January 3, 2014 - link
Ian Cutress - I am surprised that you seem to take heat and noise considerations so light, especially when many other reviews point out these weaknesses in the M8. And why did you not test these aspects more systematically in the review?IanCutress - Friday, January 3, 2014 - link
I didn't see any issues with heat - I stuck to ASRock's recommended power limit on the GPU and used a low powered 35W CPU rather than a full fat 4770K and overclocking. As for noise, the only equipment I own to measure noise are my android devices, which are not calibrated in any shape or form. Plus I live right next to a main road, so there is always noise of cars going past, affecting any reading. Suffice to say, it is audible at idle at 1 ft away, and does not particularly bother me at full load, but I may be biased by a large threshold due to my location.colonelclaw - Friday, January 3, 2014 - link
The key issue that Valve needs to convince the public about, with regards to Steam Boxes, is that the higher up front cost is considerably offset by the savings you will make on buying games from Steam, especially in tandem with the frequent Steam Sales, Daily Deals, Midweek Madness etc.The problem is that long-sightedness can be a bit of a hard concept for many. $500 for a console, versus maybe $800 for a Steam Box is a hard sell, even though we all know that 20 games at $60 dollars versus 20 games at $15-$20 is a no-brainer.
And that might even be a conservative analogy - I have over 150 games on Steam, at least a quarter of which are AAAs. Being a bit of a cheapskate, I only buy games on sale, yet I never have to wait long after release to do so. The added advantage of this is that if the release was buggy it is more likely to have been fixed by the time it goes on sale.

You guys need an editor who knows the English language. Reading some of your stuff is brutal.
