At under AU$300, the price is right for the LG Optimus L7,

This touchscreen, in quality and size, is about right for a prepaid model under AU$300. Its WVGA resolution would have seen the L7 in good company in 2011, but it is noticeably duller than the top guns of this year. Blacks and colours are serviceable without being exceptional in any way. Blacks, in particular, could use a boost, with blacks on-screen looking grey beside the phone's thick bezel. It does display colour gradients well, though, with only very subtle colour banding evident.

There is one UI element that we really love, though. When you pull down the navigation curtain, LG has included a row of customisable settings shortcuts, like Wi-Fi, GPS, Sounds, etc. Also, there is a button for Quick Memo, which takes a screenshot of the current window and lets you draw on it. You could, for example, capture a web page you're looking at, highlight a picture you like and make an annotation for later. Or you could create a message for friends and send the tweaked screen to them over email or a social network. Often we find the manufacturers adding features that don't have a strong everyday use, but Quick Memo is one that we could imagine using quite a bit.

To keep the costs low, LG opts for quite a low spec in the L7, starting with a single-core Qualcomm 1GHz processor, 512MB of RAM and an older Adreno 200 graphics processor. This is just not enough to power this phone in a seamless and uninterrupted way, unfortunately. From the moment we turned it on and throughout our testing period, we experienced long lag spikes, even when we were performing simple, everyday tasks, like opening our address book or accessing the images in our photo gallery.

This poor performance carries over into more intensive apps, as you might expect. Ski Safari is a game we've really been getting into lately, but it isn't as much fun when the frame rate is as low as it is on the L7.

On the flipside, battery performance is decent. We saw five hours of continuous video playback in the CNET Australia labs, and while this is far from being record breaking, it is a good day's use.

The 5-megapixel camera in the L7 is, like most other aspects, quite good for the price. You get a tiny LED flash beside the lens, which helps in low light, and auto-focus is built in to the camera software. Like most touchscreen phones, you press on the screen to adjust the camera's focal point, and you can tweak a number of settings, like the exposure and whether you want to take a panoramic photo.

What you can expect in a phone under AU$300 is a line that is shifting all the time. The LG L7 is a good example of a fully featured prepaid model, with a good basis in Android and some useful customisation from LG. The hardware and build quality could be better, though. Its plastic chassis and design are uninspiring, and the single-core 1GHz processor powering it all isn't enough to provide a smooth, seamless user experience.

GTX 670: NVIDIA is concerned about their ROP and memory performance

In a typical high-end GPU launch we’ll see the process take place in phases over a couple of months if not longer. The new GPU will be launched in the form of one or two single-GPU cards, with additional cards coming to market in the following months and culminating in the launch of a dual-GPU behemoth. This is the typical process as it allows manufacturers and board partners time to increase production, stockpile chips, and work on custom designs.

But this year things aren’t so typical. GK104 wasn’t the typical high-end GPU from NVIDIA, and neither it seems is there anything typical about its launch.
NVIDIA has not been wasting any time in getting their complete GK104 based product lineup out the door. Just 6 weeks after the launch of the GeForce GTX 680, NVIDIA launched the GeForce GTX 690, their dual-GK104 monster. Now only a week after that NVIDIA is at it again, launching the GK104 based GeForce GTX 670 this morning.

Like its predecessors, GTX 670 will fill in the obligatory role as a cheaper, slower, and less power-hungry version of NVIDIA’s leading video card. This is a process that allows NVIDIA to not only put otherwise underperforming GPUs to use, but to satisfy buyers at lower price points at the same time. Throughout this entire process the trick to successfully launching any second-tier card is to try to balance performance, prices, and yields, and as we’ll see NVIDIA has managed to turn all of the knobs just right to launch a very strong product.

Like GeForce GTX 680, GeForce GTX 670 is based on NVIDIA’s GK104 GPU. So we’re looking at the same Kepler design and the same Kepler features, just at a lower level of performance. As always the difference is that since this is a second-tier card, NVIDIA is achieving that by harvesting otherwise defective GPUs.

In a very unusual move for NVIDIA, for GTX 670 they’re disabling one of the eight SMXes on GK104 and lowering the core clock a bit, and that’s it. GTX 670 will ship with 7 active SMXes, all 32 of GK104’s ROPs, and all 4 GDDR5 memory controllers. Typically we’d see NVIDIA hit every aspect of the GPU at once in order to create a larger performance gap and to maximize the number of GPUs they can harvest – such as with the GTX 570 and its 15 SMs & 40 ROPs – but not in this case.
