System Benchmarks

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 look at the POST Boot Time using a stopwatch. 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.) 

POST (Power-On Self-Test) Time

The ASUS gets the jump on POST time, even shaving almost 4 seconds off from disabling controllers. The GIGABYTE result stands around 20 seconds by comparison.

Rightmark Audio Analyzer 6.2.5

Rightmark:AA indicates 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.

Rightmark: AA, Dynamic Range, 24-bit / 192 kHz

Rightmark: AA, THD+N, 24-bit / 192 kHz

ALC887 is one of the top end 2.1 codec solutions, although here we balance SNR against cost compared to something like the ALC898.

USB Backup

For this benchmark, 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 small 30 second HD videos. 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.

USB 2.0 Copy Times

We actually had an odd issue with both of our motherboards in this review. Neither of them wanted to play ball properly with the USB 3.0 mode, which we think comes down to drivers. The latest drivers will need to be downloaded and installed for anyone purchasing these motherboards.

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. 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. This can lead to an empty audio buffer and characteristic audible pauses, pops and clicks. The DPC latency checker measures how much time is taken processing DPCs from driver invocation. The lower the value will result in better audio transfer at smaller buffer sizes. Results are measured in microseconds.

DPC Latency Maximum

I was actually rather impressed with DPC Latency, with both motherboards hovering around the 100 microsecond mark. In the past, slower systems often tend to spike outside of the normal range, but both of these do rather well.

    I recently bought the ASRock J1900-ITX for a cheap NAS/HTPC/Steam Home Streaming build, and I have to say I'm really pleased with it. It seemed like a great midpoint between the Gigabyte and Asus boards here: visual BIOS with fan controls, two USB 3.0 ports in back plus a header, DVI and HDMI both, ALC892 with optical audio out, and - this was big for the NAS part - two extra ASMedia SATA ports and a PCIe x1 slot. I stuck another ASMedia-based SATA card in the PCIe slot and shoved the whole thing in a Bitfenix Prodigy with a bunch of drives.

    I almost went with an AM1 build, but I knew that all my media and SHS worked fine with my Bay Trail tablet, and an Athlon 5350 and ASRock AM1H-ITX just didn't seem compelling at $50 more for the set (or even $25 more for an AM1B-ITX) and extra power consumption.

    Note that unless you load you system all the time, the AM1 might actually have saved you power - idle is lower in most tests than Intel.

    Could you please add AM1 idle power figures?

    I've measured 10Watt idle power behind the Pico-PSU power supply for the GIGABYTE J1900N-D3V and 6.3 Watt idle power on the GIGABYTE GA-J1800N-D2H which is the dual core edition without the 2nd GBit port, the Renesas USB 3 hub, serial ports etc.

    Top power consumption in mixed Prime95, Furmark loads including some USB peripherals was 28 Watts for the Quad and 22 Watts for the Dual.

    A Cruical C300 SSD was used in all cases, which doesn't yet support the nice power saving features of the newer Crucial SSDs.

    I've tried shutting down unused peripheral devices (e.g. serial ports, 2nd Gbit Ethernet) and limiting the PCIe speed to gen1 to see whether that had any measurable impact: It didn't for idle.

    I've been an AMD fan for decades, but I'm also trying to stay objective.

    And with regards to idle power and AMD:
    While I've measured surprisingly good idle power values for my first Trinity based APU (A10-5800K) as low as 18Watts with a high-end Asus motherboard, I'm shocked that my Kavery variant (A10-7850K) won't go below 30Watts all measured at behind the PSU.

    At the same time I've measured Gigabyte Brix using Intel A7-4500U CPUs (GIGABYTE BRIX GB-BXi7H-4500U) which achieved 7.5 Watts of idle power, but beat the A10-5800K on pretty much every benchmark, CPU, GPU or both while it didn't exceed 25 Watts of system consumption (vs. 100 Watts for the AMD APU).

    Again I'd love to be able to report otherwise, but compute power per Watt is AMD's high-end weakness and idle power the low-end weakness. Which one is more important depends on your use case but both are currently killer criteria.

    The coolest thing about the ASrock boards is that they support 16GB of DRAM!

    Officially BayTrail tops out at 8GB but this may turn out to be more of a typical Intel "product castration" feature than a hardware limit. I haven't actually tried this on my GIGABYTE J1900N-D3V and would be afraid, that the BIOS might still limit that board to 8GB, but I've seen reports of people using ASRock Q1900B-ITX or ASRock Q1900M (includes a physical PCIe x16 slot with x1 connectivity) with 16GB of DRAM.

    The power consumption delta is something I do not like. I rather see the idle and load instead. The idle tells me how much my "nas/htpc" system will consume while doing nothing. the load tells me what is the absolute worse it will consume. this allows me to weigh the options better on power consumption basis, not the delta as that's not what is going to matter when the system is going to be idling for prolonged periods.

    I decided to flip back and forth to compare the 3770 and 3740 Bay Trail T to the Bay Trail D... It's surprising how well the lower powered T fares when compared to the D.

    Table on page 1 says Baytrail graphics has 6 EUs => not correct; Baytrail only has 4EUs.

    poor poor Bay-trail GPU, only half the performance of the competing AMD part. No wonder Intel lost money in that segment. You would expect that in 2014 Intel would understand that graphical is actually what you see and use these days. Even CPU it is not faster. This is again a moment like the brazos part, this was also way better then the atom, yet the djingle and oem designs forced everybody to buy that peace of crap because there were only few brazos designs.

    pitty that we dont see amd mullin tablets for x86, no those OEM yet have to get money to be convinced from intel because they know they get poor cpu designs............... and then complain the market does not accept these tablets, i have a crapy atom tablet here which now is just a radio station, no added value at all for anything else

    consumers are losing as usual.

    Apparently, the A6-6310 has a 15W TDP and a much faster GPU, using just over half the power of the 5350. Its base clock is 250MHz lower at 1.8GHz, but has a 2.4GHz turbo. The A5 is also enabled this time around.

    I'd really like to see one of these go through some thorough tests on AT; could make for a very interesting little machine. It's just a shame that they have gone for faster RAM over a dual channel controller, but the controller itself uses less power than before which is helpful.

    Running PC games on the box isn't a lot of fun fore sure, but running Android x86 gave quite another picture: The GPU may not be able to hold water against PC GPUs but it's quite powerfull enough for any Android game and benchmark that I tried, at least at 1080p.

    Tons more CPU power than the Snapdragon 800 on my Galaxy Note 3 and GPU performance in the same region.

    Sure the Snapdragon would never dream of burning 10Watts of power for that performance, but the GIGABYTE GA-J1900N-D3V isn't meant to be carried in your pocket. As high-end HDMI stick alternative, it doesn't do too badly.

    Nor as a Windows or Linux desktop for office work.

    With Lollipop we might see these use cases merge and full desktop office suites like Softmaker's will do the transition.
