Today Lenovo is holding their Tech World conference in Beijing, and as part of the festivities they are announcing three laptops for those on a tight budget. The Lenovo ideapad 100 is a 14 or 15-inch laptop which starts at just $249, and the Lenovo Z41 and Z51 are 14 and 15-inch models starting at $499.

We don’t have the full list of available models of these devices yet, but let’s start with the ideapad 100 first. At just $249, it certainly is going to be easy on the wallet. It is available in a 14-inch model which is 20.2 mm thick, and a 15-inch model which is 22.6 mm thick. It is powered by the Intel Pentium N3540, which is a BayTrail-M class part. This is a four core model which has a base speed of 2.16 GHz and a turbo frequency of 2.66 GHz. The specifications do say “up to” the N3540 though, so the assumption is that the base model will be something else. The display is what you would expect in a budget offering with a 1366x768 resolution, and likely a TN panel. Somewhat surprisingly you can get up to 8 GB of memory, and up to 500 GB of storage through a hard disk drive or 128 GB with a solid state drive. It seems to have all of the connectivity covered with two USB ports (one 3.0, one 2.0), HDMI out, a 4-in-1 card reader, and somewhat surprisingly an Ethernet jack. On the downsides, the battery life from the 30 Wh battery is rated at just four hours, and the weight is hefty at 4.2-5.1 lbs depending on the model.

It is certainly a budget offering, but for many people this will likely fit the bill. It’s surprising they could only fit a 30 Wh battery in though on an up to 5 lb laptop, and a larger battery would make this a lot more appealing for people who need something on the go.

Lenovo ideapad 100 15

The Z41 and Z51 models ramp up the price, but offer quite a bit more potential as well. The Z41 is a 14-inch laptop, and the Z51 is the 15-inch model and both have 1080p panels, but it is not stated whether they are TN or IPS. The processing power on tap is quite a bit more than the ideapad 100 (yes it is written in all lower case in the press release) with Intel Broadwell Core i7 as the top processor available. Once again it is “up to” i7, so expect the base model to come with something less than that. The base models of both use integrated graphics from Intel, but both can be outfitted with a discrete GPU. The Z41 is available with the AMD R7-M360, and the Z51 bumps that up to the AMD R9-M375. Memory is up to 16 GB of DDR3L, and storage is up to 1 TB of HDD or SSHD. The Z models have two USB 3.0 ports, one USB 2.0 port, HDMI, a 4-in-1 card reader, VGA, and once again, an Ethernet jack. Wireless is 802.11ac as well. The 15-inch model will even be available with an optional Intel RealSense 3D camera system which should set it up for Windows Hello login when Windows 10 ships. The integrated 41 Wh battery is once again just rated for four hours though, so this is not going to be the best device for someone on the go. The 14-inch model is also a rather hefty 4.63 lbs, and the 15-inch comes in at 5.07 lbs. It is available in ebony black or chalk white, with the 14-inch model also available in crimson red.

Lenovo Z41

The ideapad 100 models will be available online and in retail stores in June, and once again starts at just $249. The Z41 and Z51 are also going to be available in June, starting at $499 for both models. The Z51 with Core i5, 8 GB of memory, and the RealSense 3D camera starts at just $599.

Depending on the prices with discrete GPUs, these could work out to be reasonable priced laptops with some gaming potential as well. We’ll have to wait and see how the pricing works out for those models though.

    Really?? It's purple on my nexus 4. This makes me sad
  • jabber - Thursday, May 28, 2015 - link

    Most Windows 8 machines I get in come with the horrid purple as standard. I set it to deep blue or grey.

    What's up with AMD suddenly getting all these laptop deals with dirt-old GPUs?

    Are they somehow offering them for free?
    And isn't that M360 with ~16GB/s memory bandwidth going to be slower than Broadwell's GT2 anyways?
  • BrokenCrayons - Wednesday, May 27, 2015 - link

    Since the M360 is essentially a rebrand of the M260, you can do some benchmark comparisons to see the relative performance compared to Intel's HD 5500. For instance, take a look at the listings here:

    http://www.notebookcheck.net/AMD-Radeon-R7-M260.12...
    http://www.notebookcheck.net/Intel-HD-Graphics-550...

    It looks as though the M260 comes out ahead in most gaming benchmarks.
  • ToTTenTranz - Wednesday, May 27, 2015 - link

    They're actually trading blows because there are two versions of the M260 (with 64 and 128bit memory). But this M360 corresponds to the slowest 64bit M260, which seems to be some 10-15% slower than the 5500 GT2 in most games.

    And I'm assuming that this Z41 model won't take Broadwell models with the GT3 GPU, which would be faster no matter what.

    Difference in price between GT2 and GT3 models seems to be $25 to $30 to the manufacturer.
    So why get the discrete GPU anyways?
  • BrokenCrayons - Wednesday, May 27, 2015 - link

    Given the M260 benchmarks aren't that far off the HD 5500 and if the memory pipeline is indeed something that hurts it enough to put it a bit behind Broadwell GT2, I really don't know if there'd be a compelling reason to bother with it. Personally, I'm happy making do with integrated graphics since games aren't overly important for me. Maybe someone a little more gaming-focused can chime in if they have some thoughts on this though.
  • DanNeely - Wednesday, May 27, 2015 - link

    AMD's lack of anything new and obligatory rebadging means that 2013 era GPU designs are still a large part of their current lineup. :(
  • zodiacfml - Wednesday, May 27, 2015 - link

    Interesting. Nice WiFi and Broadwell CPUs. The battery life is not something they left out, it is intentional. I could see it is a slim battery beneath the screen.
  • meacupla - Wednesday, May 27, 2015 - link

    Oh look, another lenovo.

    Probably has a super cheap TN panel that inverts colors at normal viewing distances, like all their other junk laptops.
  • GauravDas - Thursday, May 28, 2015 - link

    A friend of mine bought the Lenovo Z50 a couple of months back which has a 1920x1080 TN panel. I think the Z51 will be using the same panel.

    Where I live (India), plenty of people buy these budget laptops and so I have seen plenty of cheap TN panels. However, this one by Lenovo definitely has the worst display I have ever seen.

    Max brightness is pretty low, contrast is horrible and viewing angles are non-existent. You cannot show a black screen without half the screen appearing grey and washed out.

    I would seriously prefer any other 1366x768 TN panel over the junk Lenovo has put in the Z50 (and probably the Z51).
