Gaming Performance 2015

Our 2015 gaming results for Z170 are still relatively new, but the issue of FCLK settings might play a big role here. At launch, the default setting for the communication buffer between the CPU and PCIe stack was 800 MHz, even though Intel suggested 1000 MHz, but this was because of firmware limitations from Intel. Since then, there is firmware to enable 1000 MHz, and most motherboard manufacturers have this - but it is unclear if the motherboard will default to 1000 MHz and it might vary from BIOS version to BIOS version. As we test at default settings, our numbers are only ever snapshots in time, but it leads to some interesting differences in discrete GPU performance.

Alien: Isolation

If first person survival mixed with horror is your sort of thing, then Alien: Isolation, based off of the Alien franchise, should be an interesting title. Developed by The Creative Assembly and released in October 2014, Alien: Isolation has won numerous awards from Game Of The Year to several top 10s/25s and Best Horror titles, ratcheting up over a million sales by February 2015. Alien: Isolation uses a custom built engine which includes dynamic sound effects and should be fully multi-core enabled.

For low end graphics, we test at 720p with Ultra settings, whereas for mid and high range graphics we bump this up to 1080p, taking the average frame rate as our marker with a scripted version of the built-in benchmark.

Total War: Attila

The Total War franchise moves on to Attila, another The Creative Assembly development, and is a stand-alone strategy title set in 395AD where the main story line lets the gamer take control of the leader of the Huns in order to conquer parts of the world. Graphically the game can render hundreds/thousands of units on screen at once, all with their individual actions and can put some of the big cards to task.

For low end graphics, we test at 720p with performance settings, recording the average frame rate. With mid and high range graphics, we test at 1080p with the quality setting. In both circumstances, unlimited video memory is enabled and the in-game scripted benchmark is used.

Grand Theft Auto V

The highly anticipated iteration of the Grand Theft Auto franchise finally hit the shelves on April 14th 2015, with both AMD and NVIDIA in tow to help optimize the title. GTA doesn’t provide graphical presets, but opens up the options to users and extends the boundaries by pushing even the hardest systems to the limit using Rockstar’s Advanced Game Engine. Whether the user is flying high in the mountains with long draw distances or dealing with assorted trash in the city, when cranked up to maximum it creates stunning visuals but hard work for both the CPU and the GPU.

For our test we have scripted a version of the in-game benchmark, relying only on the final part which combines a flight scene along with an in-city drive-by followed by a tanker explosion. For low end systems we test at 720p on the lowest settings, whereas mid and high end graphics play at 1080p with very high settings across the board. We record both the average frame rate and the percentage of frames under 60 FPS (16.6ms).

GRID: Autosport

No graphics tests are complete without some input from Codemasters and the EGO engine, which means for this round of testing we point towards GRID: Autosport, the next iteration in the GRID and racing genre. As with our previous racing testing, each update to the engine aims to add in effects, reflections, detail and realism, with Codemasters making ‘authenticity’ a main focal point for this version.

GRID’s benchmark mode is very flexible, and as a result we created a test race using a shortened version of the Red Bull Ring with twelve cars doing two laps. The car is focus starts last and is quite fast, but usually finishes second or third. For low end graphics we test at 1080p medium settings, whereas mid and high end graphics get the full 1080p maximum. Both the average and minimum frame rates are recorded.

Middle-Earth: Shadow of Mordor

The final title in our testing is another battle of system performance with the open world action-adventure title, Shadow of Mordor. Produced by Monolith using the LithTech Jupiter EX engine and numerous detail add-ons, SoM goes for detail and complexity to a large extent, despite having to be cut down from the original plans. The main story itself was written by the same writer as Red Dead Redemption, and it received Zero Punctuation’s Game of The Year in 2014.

For testing purposes, SoM gives a dynamic screen resolution setting, allowing us to render at high resolutions that are then scaled down to the monitor. As a result, we get several tests using the in-game benchmark. For low end graphics we examine at 720p with low settings, whereas mid and high end graphics get 1080p Ultra. The top graphics test is also redone at 3840x2160, also with Ultra settings, and we also test two cards at 4K where possible.

    I'd rather have 4 more USB ports than the wireless or debug LEDs, but this product isn't really for me to begin with. Reply

    I agree with you, but 5 USB ports is pretty sufficient. Reply
  • Spyrano - Tuesday, December 29, 2015 - link

    Agreed. I've actually got this board, and those USB ports get filled up fast. Would like a few extra, vs. the debug LED that I'm not sure I'll ever use. Reply

    Ehhhh, being able to quickly diagnose a post failure is more useful to me than not needing a USB hub. Not many people have more than 1-2 high bandwidth devices connected, but even if they did, you also have the USB3.1 port at the top that you could run your 3.0 hub through with minimal impact. Also there is a usb3.0 header so there should be 2 more ports available to you, if your case doesn't have connectors you can always just just by a header to dual usb connector. Reply

    I know your feeling, still rocking my 3770k on a mATX board, and there aren't enough ports available for all my stuff (wheel, joysticks, extra programmable pads, etc).

    But to be honest, as Flunk stated, 5 ports is sufficient, as we're a minority. Got a powered USB hub with 7 ports a couple years ago, and all the "gaming" stuff connects there. Works great.

    I'd take a couple USB 2.0 ports over the sound card. Reply

    Thank you for the quality review. As you note, competition (less expensive) seems to come from motherboards in the Asus portfolio, including: https://www.asus.com/Motherboards/Z170I-PRO-GAMING... . Reply

    Thank you for in-depth review! Sadly Asus is still repeating its old mistakes. First is 3-jack audio. Second, lacking in back USB department. Third, why they try to push DIMMs in premium (read: packed) form factor? SO-DIMMs would allow either dual channel or more space. M2 port is missing, nobody uses and will use U2. M.2 disk should be on the bottom side of board. Board lacks USB 2.0 ports (not everything works on 3.0, sadly). And while I'm personally baffled by people using wireless network on desktop computer, 2x2 is just a waste. For this price either include solid 3x3, or none at all. This board tries, tries, but lacks in every aspect it tries to conquer. Reply

    Does any mITX motherboard out there currently fit your requirements? I agree M.2 is a glaring ommission, but a world without wireless is a disaster even on a desktop PC, and especially on a mITX motherboard where I/O ports are constrained. Reply
