System Benchmarks

Power Consumption

Power consumption was tested on the system while in a single MSI GTX 770 Lightning GPU configuration with a wall meter connected to the OCZ 1250W power supply. This power supply is Gold rated, and as I am in the UK on a 230-240 V supply, leads to ~75% efficiency > 50W, and 90%+ efficiency at 250W, suitable for both idle and multi-GPU loading. This method of power reading allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency. These are the real world values that consumers may expect from a typical system (minus the monitor) using this motherboard.

While this method for power measurement may not be ideal, and you feel these numbers are not representative due to the high wattage power supply being used (we use the same PSU to remain consistent over a series of reviews, and the fact that some boards on our test bed get tested with three or four high powered GPUs), the important point to take away is the relationship between the numbers. These boards are all under the same conditions, and thus the differences between them should be easy to spot.

Power Consumption: Long Idle with GTX 770

Power Consumption: Idle with GTX 770

Power Consumption: OCCT Load with GTX 770

The ASRock leads the way in power consumption across the board, although the GIGABYTE has the smallest idle-to-peak delta. It will be interesting to see if this 20W window during our OCCT tests is prevalent among other X99 motherboards.

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.) 

Windows 7 POST Time - Default

Windows 7 POST Time - Stripped

The new X99 POST sequence involves a fair amount of DRAM training (testing and verifying speeds) which adds an abnormal amount of time to the POST sequence. This is why every motherboard at default scores above 21 seconds. Not only this, but most of these BIOSes are not fully optimized in order to save time. X99 launch was rushed due to Intel, so it might be the case that we see faster times later on in the life cycle of the platform.

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

The ASUS takes the lead in THD+N by a long way, and the differences between the ALC1150s and the ALC892 in the MSI show up in the Dynamic Range tests. Unfortunately the GIGABYTE had an issue with its test, causing high levels of software-detectable distortion at high volume levels.

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.

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

DPC for X99 is quite impressive all around, with every motherboard scoring under 100 microseconds.

    ASUS also has the X99-A at launch, at least here in Europe. Reply

    Ian, thanks for a great job overall on this article. I especially appreciated your clarity on how the PCIe and M.2 configs work. Reply

    Sounds like the Asus X99-A is the one for me. It keeps all the good stuff about the X99-Deluxe and saves $125. I don't need so many SATA or USB ports, I don't need wifi or dual GbE. I get the pile of fan headers and great sound, BIOS, and overclocking. Now I just need to know where the sweet spot is for memory count, speed, and timings. I suspect that's next on Ian's list. Reply

    Great roundup review. ASUS is falling lately. Did you guys heard about the burnt motherboard that their X99 had? I wonder how many people have this issue. Reply

    So somehow you have determined it is a great roundup without even reading the first page? Reply

    This is a really poor anti-ASUS shill comment. Reply

    i have the MSI x99s sli plus and its great. its beautiful and feels premium. http://imgur.com/Q7u6qjD
    not sure why the article say its not for overclockers. i overclocked my i7 5820k to 4.6ghz easily and its running stable. i don't need so many extra ports or wifi. at $230, its a great value for such an awesome board.

    Because then you won't spend twice the price for a more expensive board. Reply
