GPU Performance

Although the X1 Carbon is not a gaming laptop, we can still run it through some of our GPU tests to see how the i7-5600U performs. This is HD 5500 graphics inside, which is a 24 Execution Unit (EU) model integrated with the CPU. It has a base frequency of 300 MHz, and a turbo of 950 MHz, which is 50 MHz higher than the i5-5200U that we have already seen in the likes of the Dell XPS 13. It should perform slightly better. It is a bit of a shame that the i7-5650U CPU was not leveraged in the X1 Carbon since it includes the 48 EU HD 6000 GT3 graphics, and the tray price is not much more than the 5600U. It seems like Apple is the only one who puts these in notebooks which is a bit of a shame.

Regardless, we will test what we have, and as this is an Ultrabook I did not put it through our entire gaming laptop suite, since as we found with the XPS 13, even on the value settings the integrated graphics are not really up to par for those types of games. That is why we started testing DOTA 2, which has much lower requirements, to get a feel for how these devices with integrated graphics do on less demanding workloads.

As with the system performance, if you would like to see how the X1 Carbon performs against any other device we have tested, please use our Laptop Bench.

Futuremark’s 3DMark has long been one of the standard synthetic tests, and the X1 Carbon shows that it is right where it is expected to be – at the top. With the highest turbo frequency, and the new Gen 8 graphics of Broadwell, it edges out the XPS 13’s i5-5200U in all tests.

On GFXBench, we see the same story as 3DMark. The X1 Carbon edges out the XPS 13. Intel has certainly made some gains with the Gen 8 graphics this round, but they still have some work to do here. The key of course is to keep it in the TDP they want.

Moving on, we have our new DOTA 2 test, which is an example of a real world game rather than just a synthetic.


DOTA 2 Value

DOTA 2 Mainstream

DOTA 2 Enthusiast

The reason we use DOTA 2 on these types of devices is because the system requirements are a lot lower. You are not going to be able to play big budget first person shooters with reasonable settings on Intel’s integrated GPU, but a game like this is a lot easier to handle. Even on the Enthusiast settings, DOTA 2 is fairly playable on this device, and once again the X1 Carbon edges the XPS 13, continuing on with what was seen in the synthetic tests.

Overall the GPU is right where you would expect it to be. The higher CPU frequencies help feed the GPU, and the slightly higher turbo frequency of the i7-5600U’s GPU allows it to beat out the HD 5500 GPU in the XPS 13 which was tested on the i5-5200U processor.

    +1 on HP.
    -2 Dell
    I previously bought Dells until two XPS 18's with flaky USB3 drivers that ran at USB2 speeds no matter what perpheral/cable you used. Dell blamed Microsoft. Who knows. Premium Dell price means it should be integrated. With USB2 or wireless backup the machine was worthless to me. Luckily my wife cracked the display while mopping the floor. Never been so happy.

    Bought the HP Zbook 17 last December in a minimal config. Installed a Samsung pcie boot disk xp941 which gets 800/700 MB/ss. Pulled out the DVD and it now hosts a total of 4 1TB SSD drives in a laptop form factor. Love the BIOS. Never had such a problem free experience tricking out a new computer.

    Lenovos are a joke. People associate them with "business" and "reliability" and unfortunately put their dollars in an inappropriate place.

    The ASUS Zenbook line far exceeds what you get from Lenovo. The current Haswell UX301LAA is a marvelous piece of technology. HiDPI screen. i7. Iris graphics. 8GB ram, 512GB SSD. The new Broadwell version is coming out soon and will blow any other laptop - sans discrete cards - out of the water in every category (cpu, graphics, IO, battery life).

    It's time for people to wake up and stop drinking the Lenovo / ThinkPad coolaid. They're not the prized, derived from the Gods, piece of hardware any longer.

    This review is missing a conclusion. The basic question is: given everything else out there, would you buy the thing with your own money? If not, what would you buy instead and why? The initial tone of the review is almost an advertisement, but then slides down after the CPU charts. What's your verdict? Reply

    The X1 was one of the ultrabook PC's for business users I evaluated, but in the end I choose the Fujitsu U904. Lighter, and with better specs, even if it still does not have a Broadwell CPU.
    I hope Anandtech take a look at the U904, which for me is the best ultrabook in the market.

    if this had the i7-5650u with 6000 graphics and double the eu's at 48 I would of probably bought it. Would of preferred the 1920x1080 screen being ips. If you game at 1920x1080 its going to look better on a native 1920x1080 screen. Also less pixels means larger pixels that let more light through increasing battery life as well as less pixels to process. Also wouldn't mind if they made it a little thicker and heavier and bumped the battery up to 75wh 50% more than the 50wh battery.

    If only I could have that laptop changed to those specs I'd be a buyer 100%

    Are they still shipping their computers with malware/spyware rootkits installed?

    I have found ThinkPads to be my preferred laptops for two reasons : full maintenance documentation available online, the keyboard/trackpoint.
    I still have a T41p kicking around, a X61 Tablet and a T61p. Only the T61p had given me a problem with the nVidia graphics adapter. Lenovo had made a recall, but it failed 3 after it had expired.
    Great machines - no need to replace my X61 Tablet, so I am sticking with that for now.

    HP Elitebook/Zbooks will have the same documentation and also has a pretty good keyboard and trackpoint. Their service has been exemplary as well giving me fast turnaround for a simple loose power connector. Reply

    I have yet to find a track pointer implementation that's come close to thinkpads. and I have used 4 elitebook/zbooks including the very last generation of them, and number of dell workstations. my work always has HP/Dell but my personal purchase is always thinkpad just for the track pointer. the fact that you even mentioned "trackpoint" in Zbooks means you don't use the track pointer at all.

    truth to be told. I desperately want another manufacture to come up with a decent trackpointer so I can dump thinkpad line.

    What OS was this laptop tested on, or can The Lenovo ThinkPad X1 Carbon miraculously run sans OS? Just curious! Reply
