    Phoronix: Intel Core i7 2630QM

    If you are in the market for a new notebook with an Intel Sandy Bridge processor, one of the higher-end offerings is the Core i7 2630QM, which is a quad-core processor with Hyper Threading that boasts a 2.0GHz base frequency but can ramp up to 2.9GHz thanks to Turbo Boost. In this article are some Linux benchmarks of the Intel Core i7 2630QM compared to other mobile Intel CPUs.

    I have this processor on my Envy 14 2002ea laptop and it flies!

    Michael does the laptop you've reviewed work with switcheroo? Also is AES enabled in the BIOS?

      I have a laptop Core i7-2820QM, which runs Gentoo. It compiles software quickly.

        So quickly I've started adding -j 9 to all my emerges

          I am a but curious that nothing was mentioned about the temperature . This thing runs pretty hot. I have this CPU on a Asus G53SW and when I compile stuff on Gentoo like kernel, it easily reaches 80C, sometimes nearing 90s, even on this big chassis machine.

          Of course, it is a very fast CPU. I mostly use "make -j4" -- I am still not very sold on the hyper-threading thing, besides I don't want my machine to run too hot, and leave some CPU left for doing other tasks while compiling too. Also, as I remember, the difference between "make -j4" and "make -j8" while running a "emerge -e world" was 13 hours versus 12 hours (using "genlop -p"), so probably just an hour here or there -- perhaps many ebuilds force single thread.

            I found the oposite it's the coolest running laptop I've ever had. Do you have the correct power management options switched on in the kernel?

            I use make -j9 in my make.conf and -j 10 when I emerge the -j10 on an emerge will run 10 parallel jobs (if possible) which is great for virtual packages

              I am pretty sure of the power management stuff in kernel (see http://hirakendu.mooo.com/helium-sou...ken-out/config for example). Besides, the idle temperature is usually in 30s or 40s (and runs at the usual 800MHz) and for moderate load, it is usually below 55C. I would also say that temperatures of 70s and 80s during compiling are not very surprising, at least for the desktop counterparts of these CPUs, and I believe the thermal threshold for throttling for this CPU is 90C, although I haven't seen it go there any time. (100C is the limit of desktop CPUs and I did see my Core i5 750 desktop (overclocked to 3.5GHz) reach that point and throttle down automatically.)

              I think part of the reason for the high temperatures are also the materials of this notebook (lesser metal, possibly even the rubberized palm rests) even though I believe it does have a big copper heat sink and overall a big well ventilated chassis.

                You have quite a lot set to y and m for a gentoo user. I'll look up what config option it is and confirm if you have it or not when I get home

                Feel free to prod me on mike at fireburn dot co dot uk if I haven't replied within a few hours

                  That is correct, and the reason being it is meant to be a bit generic and run on quite a few different machines. In general, I compile Gentoo on my desktop (not the best idea to do long compiles on a notebook), make images and transfer them to other machines.

                  Frankly, while I am currently in one of those times that I don't tinker with my system and want to keep it running that way (since it is a perfectly fine system to my liking and also busy with work), useful suggestions are always welcome - I would also suggest not to spend much of your precious time on my config .

                    I cannot confirm the temperature problem on my Clevo Laptop. It's used as a desktop replacement so does all the tough stuff. With make -j9 it isn't even used 100% probably you could adjust your portage niceness?

                    At the moment it is ripping a movie:
                    Code:
                      Current Frequency 3285.38 MHz [99.74 x 32.94] (Max of below)
                            Core [core-id]  :Actual Freq (Mult.)      C0%   Halt(C1)%  C3 %   C6 %   C7 %  Temp
                            Core 1 [0]:       3221.02 (32.29x)      6.69    29.9    9.57    1.45    49.7    54
                            Core 2 [1]:       3132.71 (31.41x)       1.2    7.43    3.87       1    86.1    52
                            Core 3 [2]:       3285.38 (32.94x)      98.9       0       0       0       0    65
                            Core 4 [3]:       3155.20 (31.63x)      1.18    3.92    3.13       0    91.3    54
                    So it barely goes beyond 60 degrees.

                    //edit: that was measured with i7z...

                      Couple of things:

                      1. Thanks for introducing me to the i7z tool, which I didn't know about earlier. I also enabled cpu msr support in my kernel which I didn't have earlier (and i7z requires it for detailed statistics), so now I can see the turbo clocks too .

                      2. Second, I meant that the CPU temperatures are high when it runs at full load, for example while compiling kernel with "make -j4" or emerging some gentoo packages like gcc (without any renicing). (And even then, I have never noticed any slowdown.) For example, running a simple openssl benchmark (which runs 8 threads)
                      Code:
                       # for i in $(seq 10); do openssl speed aes-128-cbc -multi 8; done
                      will make my CPU temperature go to 70s or 80s after a minute or so as shown in the i7z output below. (Can press ctrl+c at any time to stop the benchmark.)
                      Code:
                      Socket [0] - [physical cores=4, logical cores=8, max online cores ever=4]
                        TURBO ENABLED on 4 Cores, Hyper Threading ON
                        True Frequency 2094.75 MHz (99.75 x [21])
                        Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is  29x/28x/26x/26x
                        Current Frequency 2498.54 MHz [99.75 x 25.05] (Max of below)
                                 Core [core-id]  :Actual Freq (Mult.)      C0%   Halt(C1)%  C3 %   C6 %   C7 %  Temp
                                 Core 1 [0]:       2498.54 (25.05x)      99.9       0       0       0       0    84

                          I think I didn't make myself clear enough:

                          1. This CPU runs hot when running on full load. Period.

                          If one wants to reproduce the benchmarks in the article, at least the CPU intensive ones, the high temperatures should be noticeable. Things may vary depending upon the cooling system of the notebook (how good the fan and ventilation systems) are, room temperature and other things. But in a normal room at about 23C, it would be hard to keep the temperatures below 65C or 70C when the CPU is running at close to 100%. And that is hardly a surprise with 4 cores running at 2.5 GHz turbo and consuming close to 40W for CPU alone. While to most people interested in this CPU, it should be obvious that high performance comes with high power dissipation, I just stated explicitly as to how hot it gets.

                          2. I don't have any issues with my machine, hardware or software. Even if any, they are minor and very reasonable and I am perfectly happy with it. Furthermore, it is not worth my time and effort to get some marginal gains.

                            Same here on all my desktop replacements in the last several years. Browsing many repiews, HP Pavilions (on my 5th now) have value for $, on slow usage. But professional reviewers, + YouTube tutorials, + HP's official website, show the HP do not know how to create notebook cooling. Mine breakdown just after warranty expires.

                            Only one model of one brand has self-cleaning, optimal air-flows. Can't remember now - I buy on $ value as they breakdown. YouTube tutorials will assist breakdown delay. USB external fans, routine cleaning are compulsory - but the sellers carefully do not explain this well. Their motives: more sales, more profits.
