System Performance

Intel’s Broadwell rollout has been fairly drawn out, with the first chip made on the 14nm process being Core M way back in October 2014. At CES, Intel launched the Broadwell-U processors which were 15-28 watt TDPs, but all dual-core. With Intel trying to make a bigger push into mobile, even the Atom processor got moved to 14nm before the quad-core Core parts, but finally as of June 2nd, Intel launched some quad-core laptop parts and a couple of desktop parts.

MSI sent along the latest update to the GT80 Titan which is powered by the Intel Core i7-5700HQ processor. As with any CPU update, Intel has made a few tweaks to the architecture which will gain a few percentage points in IPC, however this is in essence a die shrink on Haswell, so we have to keep expectations in check. What we have seen on the Broadwell-U line is better battery life, and a nice boost in performance by the processor being able to maintain higher turbo frequencies while keeping within its thermal envelope.

With a TDP of 47 watts, the i7-5700HQ, it will be interesting to compare how the Broadwell quad-core parts compare to Haswell. The i7-5700HQ has a base frequency of 2.7 GHz and a turbo of 3.5 GHz. There is not a perfectly comparable Haswell part that we have tested however the i7-4720HQ has been in several devices this year and has a slightly lower base of 2.6 GHz and a slightly higher turbo of 3.6 GHz which should make an interesting comparison.

I have put the GT80 Titan through our standard laptop workload, and picked some comparative devices. Take note that the Clevo P750ZM actually has an 88 watt desktop CPU inside. The MSI GT72 Dominator Pro has a 47 watt TDP and the same 3.5 GHz turbo frequency so it should be a great comparison for Haswell versus Broadwell. If you want to compare the GT80 Titan to any other laptop we have tested, please use our Notebook Bench.

PCMark 8 - Home

PCMark 8 - Work

PCMark 8 - Storage

PCMark 7 (2013)

PCMark tries to simulate some real life workloads, with several different subtests for different sets of tests. It is not a pure CPU test, and also factors in memory, storage, and even display resolution. The GT80 does not outright win these tests however it is competitive. The two SSDs in RAID 0 help boost it to one of the higher storage scores, and for the target market the extra cost and loss of battery life of RAID 0 is fine. One thing to note is that the Creative test on PCMark 8 would fail to run on this device, so there was no score recorded for that test.

Cinebench

Cinebench R15 - Single-Threaded Benchmark

Cinebench R15 - Multi-Threaded Benchmark

Cinebench R11.5 - Single-Threaded Benchmark

Cinebench R11.5 - Multi-Threaded Benchmark

Cinebench is more of a pure CPU test, and it favors high frequencies and IPC. Here we get a better feel for Broadwell and the i7-5700HQ performs very well. It outperforms all of the other 47 watt processors we have tested despite not having the highest turbo frequency.

Once again, the i7-5700HQ outperforms all other 47 watt parts although it can’t compete with the 88 watt P750ZM. The move to 14nm clearly opens up some additional headroom to keep the turbo frequencies up.

Web Tests

Mozilla Kraken 1.1

WebXPRT

Google Octane 2.0

Our web tests continue the trend that has already been set. Once again the GT80 Titan sets the standard, and is only trumped by a notebook with a desktop processor.

Broadwell may just be a die shrink of Haswell, but the 14nm process is very effective. Despite having a maximum frequency of just 3.5 GHz, the i7-5700HQ outperforms Haswell parts that can turbo up a few hundred megahertz more, which is pretty impressive.

    How do I win this bad boy? I'd take it out for a sweet lobster dinner, after which I'd definitely upgrade its ram and OC its GPU.

    Might be a noob question...but can someone PLEASE tell me why they use So much More vram in the mobile gpus? ty

    Is it just the easiest way to up memory bandwidth in a more power-"sensitive" design? Hopefully I dont sound like the novice that I am but I'm trying to learn as much about electronics as possible.

    I really wish there was a way to buy these and use it in a desktop system. This would be IDEAL in a passively cooled case (HDPLEX, etc) with a desktop top end Haswell or Broadwell CPU. HDPLEX just announced a passively cooled 300w power supply... Would love a ~3.8ghz quad core CPU and these two GPUs connected to a 1080p TV. Blow any xbox1/PS4 out of the water PLUS HTPC...

    I registered just to say that the graphs in your systems reviews are meaningless. I have no idea how fast an Alienware 18 is, and while I can google it I have no idea what config you are using to make to graph. This is true for every review except single components. Laptops, nettops etc are hopeless to get anything from.

    There's one thing i dislike about gaming laptops, and this is the reason i went back to a desktop.
    1: U can't swap hardware in your very expensive PC (an issue thankfully adressed by MSI here)
    2: They require good cooling, but for some stupid reason u always have to split the laptom into atome to get to the coolers and clean them, voiding warranty in doing so.

    And for step 2, that's one thing i'd like to see included in the tests, how easy (if possible) is it to clean then cooling, that obviously need to be in pretty good conditon to move the amounts of heat generated by, especially gamer laptops. (maybe this will have the companies think about giving the customers an easy option to clean the cooling on laptops as this could be a good sellingpoint over a competitor that would charge 100$ for a cleanup)

    1) is not an issue, you can swap HDD, SSD, RAM like on regular desktop. CPU + GPU on mobile gaming laptop usually are good enough to get you through 2-3 years and then you just get new laptop with new tech anyway.

    All that said I prefer desktop too from simple price point. One can get the same performance on desktop for usually half price of gaming laptop.

    Love the keyboard position on reviewed laptop.

    You are entirely wrong. Proper gaming laptops allow you to customize and upgrade EVERYTHING, which includes CPU, GPU, ram, storage(s) and display panel. And I doubt any proper gaming laptop forbids you from tearing it down, they are no silly apple product for total noobs.

    As soon I win the lottery, I'm buying one of these. It outclasses my old desktop as it is.

    Any notice of microstutter on this machine?
