    Great, they have put anti-turbo to them. Well, at least there is 4 cores, 2 core i7 was bit funny.

    Too portable, these are much better in design, yeah it is just a PC with handle on side and display/kb glued to side :D

    They also have these kind of things, fanless i7, which they claim should run even in 70C heatwaves, considering they sell those in India, I would guess they need to work in hot weather too.

    Lot of different interesting toys there, much better than consumer grade thin junk.

    agree, i hate thin stuff. Everything is sacrificied for thin-ness. (thickness :p). Batteries shrinking (seriously the amount of money i am paying for this laptop, im sure you can have a 100whr battery). Cooling is shocking in some laptops. Minimum two fans, unless it's designed really well imo. Keyboards getting thinner, like 0.3mm travel distance, no thx.

    Also whatever happened to removable batteries! This leads me harping back to Clevo again, they don't care about thickness, has upgradability, battery size is quite high (63whr is decent) and can be swapped. Not like the dual battery machines i used to love, but good nonetheless.

    You might wonder why i don't just get an old laptop, but the issue is media, HEVC doesn't play well with old stuff. and stuff like NVENC etc. HEVC encode is important for me.

    Planning to find a new music streaming service because of all those bad news Spotify have. I'm thinking about something like Apple Music or Tidal as a replacement service (Google Play Music, Pandora and some else are not available in my area, and some services are not that good IMO). Any good music streaming services out there?

    Also on the 24in monitor, it's got wayy slimmer bezels than my Viewsonic one has. So it literally feels massive, i thought it was bigger until i measured it. 24in but they look so different. Also my Viewsoinic i was sketchy about the image quality, text is fuzzy on it, and in hindsite i really should have RMA'd it, the acer monitor i have now is head and shoulders above it. Even my 2004 monitor has better sharpness than that £200 thing!

    I believe if you lower the dsr smoothness, it can make text/textures clearer to read.. I set my desktop to 3840x1620, and turned up the display scaling in windows. My games are able to run in window mode at any res.. Here's a video of bf1 I did a week ago with dsr on. I think it looks better.. Obviously there's a performance loss, but I still had a good match until my game crashed as I overclocked my gpus memory too high :/

    I mainly did this to lower cpu bottleneck I have. Bf1 and multiple other games are straining the crap out of my i7 2600 even though its bclk overclocked. My gpu is around 50-80% load and spikes to 100% every once in a while. My cpu is around 40-50% total thread/core usage.

    I don't think that increasing GPU load classifies as reducing CPU bottleneck, it would be more like masking CPU bottleneck.

    Only in case where game at lower resolution + DSR would actually run with lower CPU load than game at higher resolution, that would make CPU bottleneck less.

    Probably single core limits, that is very common with DX11 games.

    ughhh, still got some gripes with laptops:
    Why do Intel H series CPUs exist... Yes they have good performance as they use more power, but why not get a U series CPU, which has good idle consumption, and have it have like unlimited TDP. 4c at 4.0 GHz like the i7 8550U is strong performance, and at idle doesn't use much power at all. Imo the H series is just a way for Intel to flog their worst silicon to laptop manafacturers.

    i7 8550U + GTX 1050ti (when will we get new GPUs :p ) + 100whr battery=best laptop on the planet.

    Also empty space really annoys me, like here, a GPU fan, space all around it and the GPU can't hold it's base frequency. *sobs* why clevo whyyyy */sobs* csm_IMG_2818_ab93bf8e12.jpg

    With HP, that fan would be other way around, so that it would try to gasp air from 1mm gap and there would not be empty space or space for air to move at all. I think they have empty space there to let heat pipe dissipate heat there as their useless whiny fan design is not sufficient to move enough air :D

    3x 40mm fans vertically to back wall there would do some air flow at least, one end of laptop should be filled with fans, that constantly run at low rpm, drawing air from other side of the laptop, trough fins that dissipate heat. Cold air in, hot air out, constant steady flow.

    Cooling first, performance 2nd, looks and fashion should not have much weight on design. Sadly that is not how computers sell and laptops are not as good as they could be.

    Besides, when you carry 15kg suitcase, it is improving fitness, which is good for you, so light laptop is a health hazard, there, that should be a thing, let's start demanding heavy bulky laptops as it is healthy and trendy, how you start those internet things this is one aspect that would need to be a craze? :D

    actually the U SKUs are the ones I was slagging off earlier, which never hit 100% CPU load without throttling themselves on modern SKUs

    implementation issue, not the CPU's fault. The cTDP is a double edged sword, but ofc manafacturers will slow down the chips, to reduce power use, less cooling, less battery size = thinner laptop.
    A U series processor in something designed for a 45w chip would absolutely fly, that is if it wasn't on TDP limits, it would be hitting those high turbo boost clocks all day long, and then when not in use, it will use little power due to it being a ULV variant.

    all i know is it is a health hazard to have a 50c laptop on your lap. That is un-acceptable temps.

    I have an HP and i know what you mean, it draws air through the keyboard and doesn't do much, if you remove the keyboard it runs fine. Tempted to drill holes in the bottom of the laptop to give the fan some air!

    It's Intel's default tune that caused us issues in our testing, duplicated on multiple machines

    So I recently acquired two free 2011 MacBook Pro 15" models with faulty AMD GPU's (known issue, Radeongate). Today I transferred some parts from the worst one to the best one. Installed an SSD that was lying around, and disabled the defective AMD Radeon HD6770M GPU permanently (via Ubuntu boot).

    I'm surprised how smoothly OS X Yosemite runs on the default Intel HD 3000 GPU. Even using the 3d function in Maps worked smoothly. I suspect the rather low-res resolution of 1440x900 helps with that.
    20181010_152145.jpg
    These machines were the first MacBook Pros that used Sandy Bridge quad core i7 CPUs, and tend to run really hot. This one idles at around 38 degrees celsius with the fans running at idle. I've added a custom fancurve which ramps up the fans more quickly. The CPU temperature under heavy load is now around 75-80 degrees celcius, at ~80% fan speed. Before, the CPU temperature would have to reach 85-90 degrees celsius until the fans even started to ramp up from idle!
    20181010_152244.jpg
    I use GfxCardStatus to detect if the AMD GPU will still pop up in certain cases. It's not. The icon stays in 'i', while it would change to 'd' if the AMD GPU were enabled.
    Overall I really have to say I'm quite pleased with the MacBook. It still works fast and smooth after 7 years, even on the default HD 3000 graphics. Even the battery is, after 976 load cycles, perfectly fine with 94,5% capacity left. In short, a good score!

    Detailed specs:
    -Intel i7 2760QM @ 2,4 Ghz -- Sandy Bridge, 4 cores 8 threads
    -Intel HD 3000 "512 MB"
    -AMD Radeon HD 6770M 1024 MB: Defective and disabled
    -8 GB PC3 10600 RAM @ 1333 Mhz
    -1440x900 15" screen

    Yeah the fan curve is probably why the GPU failed in the first place tbh

    Honestly,I'm thinking that U-series Core i7 shouldn't exist, since U-series Core i5 has the same amount of cores and a 1~5% performance difference.

    For instance a used Dell E6440, with an Intel Core i5 4300M (faster than the U models). Sturdy laptop w/ good build quality, easy to work on, put in an SSD and it'll work really well. I like the keyboards, too.

    @Michaelflat Exactly. Moreover, there's kind of a design flaw: "The Radeon GPU, a which frequently varies in temperature depending on load, is connected to the motherboard via a lead-free solder which becomes brittle through repeated thermal cycling. This results in cracks which interfere with the GPU's operation, manifesting as graphics corruption, crashes, and entirely dead laptops." (Bit-tech.net)

    It should, but should have a 25w TDP. The i5 is maxing the TDP and so not much difference between the two.

    Heh, nice. Did you set up your own boot server?
