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.

    Is the trackpad a Precision Trackpad? Reply

    $2100 for ultrabook?

    I recently got a clevo laptop with IPS screen, i7-4790K 4Ghz CPU, 16GB ram, 980m and XP941 SSD at around $2300. Yes I do own a thinkpad too but I think the price is a bit excessive. Do the carbon models also have magnesium roll cage other thinkpads have?

    I been looking to update my IBM Thinkpad Z61T and this might be the one to get! I will wait for it to come down to my price before I look at it closer however. I usually, have not spend more then $700 on a Thinkpad since the 600X which was fully loaded and I paid full price $3,300! Never do that again! That was back in the 1980s?? and in real dollars; that like $10K? now! I did it because it was business expense and at the time you could use accelerate depreciation and do about 1/2 of it for taxes. But I would never buy it that way for personal use. Total waste of hard earned money! Reply

    The new X1 looks nice, but I'm surprised that anyone is willing to trust this company again after they so irresponsibly compromised user security with Superfish. Reply

    Oh man, I was so looking forward to this. If it had come with a 1080P IPS, non-touch panel with a matte finish, I'd have been all over it. A larger battery would have helped sell these as the current one just does not last long enough. And not including 8GB or ram by default? Come on now. I can get all of this for $699 in an Asus zenbook today. Get in the game Lenovo. Love the X1 Carbon, but I just can't force myself to over pay by this much for it. Reply

    using a laptop as a music production workstation i can`t help looking for an ExpressCard slot.
    it seems that only Lenovo and Dell` s Precision has one.
    Dell Precision doesn`t seem to have a M2 slot though..
    I bought a ThinkPad T540p last year with a 3k ips screen.
    it had problems with the power supply, the laptop wouldn` t recognise it every time.
    did some research, called lenovo, told them about the problem and that they should send me a power supply manufactured by Delta instead.
    I received it after a few days from Holland and no problems after that.

    It seems that either HP or Asus are building workstation versions.

    HP also have a mobile workstation line: HP Zbook 14/15/17
    HP Zbook 15 is a competitor for ThinkPad w540/541 (4cores) while HP Zbook 14 is for ThinkPad w550s (2 cores ULV 14vs15)
