Introducing the Lenovo IdeaCentre A7

As we mentioned in our recent review of Dell's enterprise-class all-in-one, the OptiPlex 9010 All-in-One, balancing the needs of an all-in-one system and making it feel like a solid alternative to a conventional desktop is a difficult process. By potentially grafting an entire computer to the back of a display, you immediately reduce the thermal headroom of the hardware by a substantial degree. You're also dealing essentially with most of the trappings of a notebook in a much, much bigger body.

On hand today is Lenovo's consumer-grade IdeaCentre A7 all-in-one, and it's a surprisingly solid offering in a product category that seems to be continually struggling to find its true niche and identity. When you buy an Apple iMac, it's because that's the only desktop Mac in that price class, but an all-in-one PC must contend with discrete desktops in its category and offer a reasonable value proposition. Did Lenovo produce a solid offering, or are they offering an answer for a question nobody asked?

Evaluating all-in-ones is a tough call, and vendors have to make them appealing enough to outweigh their flaws. They're essentially notebook computers with giant screens but without batteries, sealed up about that tightly. It's true that very few people outside of enthusiasts upgrade their processors or motherboards, but video cards have become increasingly relevant even for regular users, and that's a sacrifice the informed shopper has to consider. There's also the fact that when the computer half of an all-in-one ages and isn't as great as it used to be, you wind up potentially tossing a quality monitor in the process. An all-in-one's lifespan could very well become severely truncated compared to a garden variety desktop, so the all-in-one has to provide a distinct enough experience and justify itself enough to warrant the loss in longevity.

Lenovo's ThinkCentre A7 may very well have done that.

All-in-ones continue blurring the line between notebooks and desktops by often incorporating a mixture of notebook and desktop-class hardware with varying degrees of success. For what it's worth I generally prefer the use of notebook-class hardware as with Sandy Bridge and now Ivy Bridge, the CPUs are typically fast enough. NVIDIA also has a big winner with the Kepler-powered GK107, but unfortunately Kepler isn't making an appearance here as Lenovo has gone with last generation's less powerful (and ultimately less efficient) Fermi architecture.

The Intel Core i7-3610QM may be the entry level of Intel's mobile quad cores, but that doesn't mean it's underpowered. As a quad core processor running at a nominal 2.3GHz on Intel's Ivy Bridge microarchitecture it offers plenty of performance on its own, but it's also able to turbo up to an impressive 3.1GHz on all four cores. Unfortunately Lenovo made what I consider a substantial gaffe with their graphics hardware.

It may have a current-generation moniker, but the GF108 GPU powering the GeForce GT 630M is three generations old now, and dumping 2GB of DDR3 on it doesn't take any of the stank off of it. With just 96 CUDA cores it's underwhelming, but the clocks are actually quite good at 800MHz core/1600MHz shader. (Note that NVIDIA's own control panel System Information utility incorrectly reports what would be an embarassingly low 475MHz core clock/950MHz on the shaders.) Even so, the GT 630M is underpowered and unworthy of being in what's essentially a flagship consumer all-in-one, as GK107 is faster and uses less power. Unfortunately the 630M isn't leveraging Optimus either; while Optimus is substantially less relevant in a desktop system, not enabling it also results in losing access to Intel's HD 4000 IGP and with it, the very useful QuickSync hardware video encoder.

Unfortunately the rest of the hardware doesn't get too much better. While I'm fond of Lenovo's decision to go all-mobile with the A7, a 5400-RPM hard drive in a $1,500 all-in-one seems frankly cheap. They've also opted for all Realtek on the networking hardware instead of at least including an Intel Centrino wireless adapter, and the wireless connectivity is strictly 1x1 b/g/n. There's a TV tuner included, but I'm dubious as to its value.

Thankfully things do pick up when it comes to the display. While Lenovo is still using a 1080p panel at this 27" form factor, it's an IPS panel with multi-touch built in, making it ideal for when Windows 8 drops.

    From the way the hinges appear, it looks like the base can sit flush with the monitor? If so, is there some kind of mount on the bottom of the base so you can wall mount it?
  • SunLord - Wednesday, September 26, 2012 - link

    It seems the hinges are so you can move the display down at a steep angle and use the 10point multi touch screen or that's how it looks like it's meant to be on the lenovo website

    ... Yet Lenovo leave those problems in.
    I mean really, I didn't even know there were 27" 1080p IPS panels, but if there are, they must be destined for low end TVs only. I'd much rather see a 24" 1920x1200 panel.
    As you said, why not a Geforce 650M?
    Dodgy Realtek networking aside, what the hell are they doing putting a 5400 RPM HDD in ANYTHING these days?
    Especially in a high cost machine.
  • Snotling - Wednesday, September 26, 2012 - link

    Yeah, penny pinching @ho!es. 7200RPM drives cost almost nothing more, that's just screwing with the uneducated buyer.

    The display's low resolution for its size also gets a +1

    I couldn't care less about the G630M, those machines are not in any way designed for gamers anyway.
  • Meaker10 - Wednesday, September 26, 2012 - link

    Its a 2.5 inch drive and 1tb 7200rpm drives dont exist in standard height. The next best is 750gb 7200rpm which is quite a drop.
  • Death666Angel - Wednesday, September 26, 2012 - link

    Considering that this is not a standard case, I don't see why 15mm vs 9.5mm is an issue. Cost might be, but probably not height. Also, I don't see 750GB as "quite a drop", the people I know who would use an AIO don't use a lot of data on their PCs, they have no big movie collections, and their photos/music/data is easily stored in 320GB drives. :)
  • Meaker10 - Wednesday, September 26, 2012 - link

    Its a numbers game and 15mm drives are noisy, power hungry and less reliable, also at that point you may as well go slim 3.5 inch.

    I have 1.5 tb on an external drive with my Imac.

    I agree with Dustin, why would any sane designer add the HDMI-ports to the side while only adding a single USB-port easily accessible. What's most likely to be added to the HDMI-input? I would say a gaming console - something we don't move around very often. What's most likely being connected to the HDMI-out? A second screen of course. Something we definitely don't move around very often.. USB-sticks, external hard-drives, cell phones, cameras etc - those are the things that we may add or remove many times a day. And often connecting many at the same time.

    Same with the hard drive - the added cost of adding a small SSD could be as little as $75 but could mean a world of difference performance-wise. I'm all for keeping a conventional HDD as well for added storage. If needed - increase the size of the base a few cm.

    I don't have any issues with the resolution, a lot of people with less than perfect eye-sight find 1920*1080 on a 27" screen just fine.

    Something else I wish they would have added is mic in/out on the front *as well* as to the back. Perfect for hooking up a headset while still being able to have proper speakers connected to the back.

    Ok, a laptop could be connected to the HDMI-in as well. And if so a side placement make sense. But HDMI-out on the side...?
