AMD’s RX Vega GPUs are finally here to battle Nvidia for high-end gaming supremacy

amd vega

Nobody likes being in second place, and when it comes to PC gaming hardware that's exactly where AMD has been spending most of its time in the past decade. Today, the company launches what might be its most aggressive play for the hearts of PC gamers with a brand new line of graphics cards. The Radeon Vega GPUs are finally here, and AMD is launching not one, not two, but three of them in a new offensive against Nvidia's utter dominance.

Report: Apple in talks to acquire Imagination Technologies, likely to start developing its own mobile GPUs [Updated]

Update: In a statement to CNBC, Apple has confirmed it is not planning to make an offer for Imagination Technologies. It did however hold some talks with the company about undisclosed topics.

ArsTechnica is reporting that Apple is in ‘advanced talks’ to acquire Imagination Technologies, makes of the PowerVR mobile GPU designs Apple licenses for its A9 and A9X SoCs. The company declined comment about any such acquisition of course. Apple began using Imagination Technologies GPUs since the Apple A4 chip. Rumors have been bubbling in recent years that Apple will eventually start designing its own mobile GPUs, in the same way it designs custom CPU silicon today. An acquisition of Imagination Technologies would be a clear signal the company is moving in that direction.

Microsoft’s claim that Surface Book is twice as fast as 13-inch MacBook Pro misleading, show benchmarks

surfacebook

When Microsoft launched its first full-on laptop, the Surface Book, it made a big point of claiming that the machine was twice as fast as a 13-inch MacBook Pro. Benchmark tests by PCWorld show that this claiming is misleading, though the dedicated graphics card available in certain models does pay off for some uses.

The site’s tests showed that in pure CPU benchmarks, the MacBook Pro was actually slightly faster than the Surface Book. This remained true for Geek Bench 3 tests, which simulate real-life usage …

Where the Surface Book started to pull ahead – though still a long way short of Microsoft’s claims – was in benchtests involving processing tasks that can be shared with the GPU. While the 13-inch MacBook has an integrated GPU, the particular model Surface Book PCWorld tested had a dedicated GPU, so unsurprisingly performed better here.

It should be noted that this isn’t a like-for-like test, as the base model Surface Book, priced at the same $1500 as the 13-inch MacBook Pro used, doesn’t have the dedicated GPU – the model tested here costs $1700. Even so, there was still no sign of the doubled speed claimed by Microsoft. That difference showed up only in a pure graphics test.

Microsoft did, though, underclaim in some respects, says PCWorld: running Tomb Raider, where the Surface Book achieved 74fps against the 23.6fps of the MacBook. But that’s what a GeForce graphics card will get you.

What would be interesting to see is the same tests run against the MacBook Pro 15, with its dedicated AMD graphics card.

AMD’s Powerful New R9 Nano Graphics Card Fits In Small Places

This year, I bought myself an Nvidia GeForce GTX 970 graphics card. It was time to upgrade. And I was pleasantly surprised to find I could buy a mini version of one of the best cards ever made. Now, I can potentially fit my beefy gaming PC into a console-sized case. But a new card from AMD is about to do small and powerful even better.

Apple surprises with A8X GPU, uses exclusive ‘semi-custom’ 8 cluster design

A8X-Mockup_575px

New chip analysis of the A8X powering the iPad Air 2 has revealed that it is even more powerful than it initially appeared.

Further analysis by AnandTech showed that initial guesses as to the GPU specification of the Apple A8X chip, exclusively available in the iPad Air 2, were wrong. In fact, the chip uses a unique 8 cluster design. AnandTech describes the discovery as “even better than I thought”. Although the customizations are limited, this represents a big step for the company as it is now dabbling in both custom CPU and GPU engineering, even if the leap over generally-available components in this instance is small.

Effectively, Apple has engineered a way to stick two Imagination GX6450 PowerVR chips on the same die. A die shot sourced by AnandTech confirmed this theory, although the site is unable to publish the image. Shown above is a mockup of what is going on internally.

This is how AnandTech describes Apple’s customizations:

While Apple licenses PowerVR GPU cores, not unlike their ARM IP license they are free to modify the Imagination designs to fit their needs, resulting in an unusual semi-custom aspect to their designs (and explaining what Apple has been doing with so many GPU engineers over the last couple of years). In this case it appears that Apple has taken the GX6450 design and created a new design from it, culminating in an 8 cluster Series6XT design. Officially this design has no public designation – while it’s based on an Imagination design it is not an official Imagination design, and of course Apple doesn’t reveal codenames – but for the sake of simplicity we are calling it the GXA6850.

Apple’s willingness to change even this is a strong indicator that it will be even more aggressive with GPU designs in future Apple SOC’s. When the A8X was first revealed, it surprised with a triple-core CPU design and 2GB of RAM. Combined, the tablet represents a huge leap in performance over its predecessor.

In fact, the performance improvements are disproportionate to the hardware leading some speculation that the company has upcoming software enhancements to truly take advantage of the compute beefiness. Apple has been testing a split-screen multitasking system for the iPad, which would certainly do just that.
