ARM Develops New GPU for Low-Cost Tablets

ARM has just created a brand new, entry level version of its Mali graphics processor that, if incorporated, could expand the market of low cost Android tablets. Known as the Mali-450, this GPU is designed to help manufacturers build tablets that are less expensive than the ones currently leading the markets, like Apple's iPad which runs $399. However, these manufacturers still want good enough graphics performance to keep most users satisfied.

Touchscreens and HD video are pretty standard when it comes to tablets these days, with the GPUs in these devices accounting for a big share of the price you pay. In addition to that, more powerful GPUs take up more space on the CPU, which could also increase costs. A lot of manufacturers are looking for cheaper parts that offer decent graphics performance while also occupying less space. This is where the Mali-450 fits in.

The new GPU is offered with as many as eight cores and offers double the performance of its predecessor the Mali-400. The Mali-450 is also expected to appear in tablets in the first half of 2013 according to Director of Marketing for ARM's Media Processing Division Ian Smythe.

Tablet makers are showing an increased demand for a wide range of price and performance characteristics, which is where this new ARM GPU comes in . The company is planning on offering the Mali-T600 series for high-end devices and the Mali-400 series for low-end devices.

Both series will be able to do gaming and video playback but, according to Smythe, only the high-end parts will be able to handle "computational graphics". That includes things like matching points on two images to do facial recognition or stitching photographs together into a panorama. ARM is also developing a high-end part known as Skrymir (not to be confused with Skyrim, cheeky devils) which is due out sometime in 2014.

Has AMD Finally Topped Nvidia in Triple-GPU Scaling?

When building your own PC or even just upgrading the one you already have, you have a tendency to always go bigger. A lot of the time people do serious upgrades when they upgrade their GPU. A lot of people upgrade to the next higher model, but some double up and get two GPUs. But then there are the others who put their money down on the question of whether or not three GPUs is all that much better than two?

Nvidia has been the undeniable leader when it comes to multi-card scaling with AMD always trailing behind. However, there are a new array of GPUs from AMD that may just push them ahead of Nvidia in the multi-card scaling race. The geniuses over at Tom's Hardware loaded up a super fast computer with single, dual and triple -GPU configurations to find out the truth.

In the GPU market, everything is pretty much a waiting game. About every six months or so, either AMD or Nvidia releases a product and the other company waits to see what is going on hoping to bounce that one back by tweaking the clocks, power and configuration of their own device. Both companies do this in order to build anticipation with their followers.

Despite the hysteria in the GPU world, the past few launches have barely raised the bar at all. Anybody out there that wants to play their games at a high resolution without giving up all the juicy goodness of the game will probably have to use a multi-GPU setup.

So the big question here is not necessarily which card is better but rather which works better in pairs and trios. Buyers and enthusiasts can save a lot of money by purchasing AMD's 1 GB card. However, the newest 2 GB AMD Radeon HD 6950 is the least expensive three-way CrossFire option.

The closest competitor to this is Nvidia's GeForce GTX 5570 1280 MB GPU which also represents the cheapest current three-way SLI configuration from Nvidia. Tom's Hardware has already reported on great scaling from three-way SLI so what is probably the biggest question is whether or not AMD's scaling has improved to the point where it can surpass Nvidia. Two-way figures point to the positive and it seems that Radeon devices work together much better than in the past.

Overall, CrossFire's value-oriented win in the two-way area and the performance win in the three-way configuration setup was enough to make Radeon the clear cut winner according to Tom's Hardware. However, if that isn't convincing enough for you, then the low power consumption of the Radeon HD 6950 should be. If you want the full rundown and specifications of the tests and all the juicy details, head on over to Tom's Hardware now and check it out.
