AMD has fully taken the wraps off its brand new seventh generation APU architecture Bristol Ridge, which it announced earlier this year. It promises users around a 20 percent boost in CPU performance, and a 37 percent boost in GPU performance over Bristol Ridge's predecessor Carrizo, which launched in 2015. That's standard fare for generational updates, but what's most impressive is that AMD has squeezed this performance out of the exact same architecture as Carrizo: same 28nm transistors, same Excavator-based design.

At the high-end are the quad-core AMD FX, A12, and A10 chips, which come in 35W and 15W variants. Base clock speeds are as low as 2.4GHz in the 15W A10 and as high as 3.7GHz boost clock in the 35W FX. The FX and A12 come with up to eight GCN cores in a Radeon R7 graphics package, while the A10 comes with Radeon R5 graphics. All support DRR4 memory up to 2400MHz (versus 2133MHz DDR3 in Carrizo), which should give the on-board GPU a nice boost given how dependent its performance is on system memory.

At the mid- to low-range are the A9, A6, and E2 APUs, all of which sport a 15W TDP and more conservative clock speeds. Graphics take a cut too, with the A9 featuring Radeon R5, the A6 Radeon R4, and the E2 Radeon R2. Compared to Carrizo, these low-end chips still get a boost in performance, though, with AMD claiming clock speeds that are 1GHz higher, and up to 50 percent more GCN graphics cores. There's also support for HDMI 2.0 (finally), PCIe 3.0, and built in hardware decoding for MPEG, H.265, and VP9 video up to 4K resolutions.

AMD's first Polaris-based graphics card is here: the Radeon RX 480. Rather than launch a high-end card to compete with the likes of Nvidia's GTX 1080 or 1070, AMD's RX 480 is pitched at the wider mainstream market, offering just over five teraflops of performance for a mere $199—about half the price of a GTX 1070. UK pricing is currently TBC, but it'll probably be about £160. The RX 480 will be available to buy on June 29.

Details on the Polaris architecture—which is based on AMD's forth generation GCN architecture and a new 14nm FinFET manufacturing process—were thin on the ground during the RX 480's reveal at Computex 2016 in Taiwan, but the company did divulge a few key specs. The RX 480 will feature 36 compute units (CUs)—that's eight more than the R9 380, and just shy of the 40 of the R9 390—along with some fast GDDR5 memory attached to a 256-bit memory bus for 256GB/s of bandwidth.

The RX 480 will come in both 4GB and 8GB configurations (the former being the £160/$200 model), and will support AMD FreeSync and HDR video via its DisplayPort 1.3/1.4 and HDMI 2.0b outputs. Best of all, it has an average power draw of just 150W, which should make it cooler and quieter than AMD's previous-generation graphics cards.

Page Six, a gossip and culture spinoff of the New York Post, reported yesterday that Disney executives are unhappy with the current version of Rogue One: A Star Wars Story, the spinoff that’s supposed to tell the story in between Star Wars episodes III and IV. According to anonymous sources, the movie is now scheduled for an "expensive reshoot" over the summer, ahead of its December release.

A source elaborated that, "the movie isn’t testing well” and “Disney won’t take a back seat.”

Screen testing of a movie is common in Hollywood and tweaking the film according to the screen tester’s comments is routine, but the Page Six sources seem to suggest these alterations go beyond that.

Intel's main Computex announcement was the launch of its high-end (and high-cost) Broadwell-E chips, but the company also made a passing mention of a couple of next-generation architectures for mainstream and low-end systems that will ship in finished systems by the end of the year.

The most significant of these two architectures is Kaby Lake, the replacement for Skylake. Kaby Lake breaks from the "tick-tock" schedule that Intel has followed for most of the last decade; that schedule has been replaced by something Intel calls "Process, Architecture, Optimization," in which it introduces a new process (formerly a tock), introduces a new architecture on that process (formerly a tick), and then tweaks the architecture without changing the process. Kaby Lake is an "optimization" and will be built on the same 14nm process as Skylake.

Intel has said very little about Kaby Lake, and aside from confirming that the CPUs will be called "seventh-generation Core" processors and that they'll definitely be shipping later this year, it didn't reveal much new information at Computex. Previous rumors and leaks point to expanded 4K video playback capabilities, including support for HDMI 2.0 and HDCP 2.2 and hardware decode support for 10-bit HEVC and VP9 videos. The processors should also be socket-compatible with Skylake, provided your motherboard OEM provides a BIOS update to add support. Rumors say the Kaby Lake launch will start with low-voltage Core i3/i5/i7 and Core m3/m5/m7 CPUs for laptops and convertibles first and come to desktops later—Asus is already showing off a Surface clone with a Kaby Lake CPU, suggesting that the chip is already sampling to Intel's partners. This bodes well for its availability.

Less than two weeks after more than 177 million LinkedIn user passwords surfaced, security researchers have discovered three more breaches involving MySpace, Tumblr, and dating website Fling that all told bring the total number of compromised accounts to more than 642 million.

"Any one of these 4 I'm going to talk about on their own would be notable, but to see a cluster of them appear together is quite intriguing," security researcher Troy Hunt observed on Monday. The cluster involves breaches known to have happened to Fling in 2011, to LinkedIn in 2012, and to Tumblr 2013. It's still not clear when the MySpace hack took place, but Hunt, operator of the Have I been pwned? breach notification service, said it surely happened sometime after 2007 and before 2012. He continued:

There are some really interesting patterns emerging here. One is obviously the age; the newest breach of this recent spate is still more than 3 years old. This data has been lying dormant (or at least out of public sight) for long periods of time.

The other is the size and these 4 breaches are all in the top 5 largest ones HIBP has ever seen. That's out of 109 breaches to date, too. Not only that, but these 4 incidents account for two thirds of all the data in the system, or least they will once MySpace turns up.

Then there's the fact that it's all appearing within a very short period of time - all just this month. There's been some catalyst that has brought these breaches to light and to see them all fit this mould and appear in such a short period of time, I can't help but wonder if they're perhaps related.

All four of the password dumps are being sold on a darkweb forum by peace_of_mind, a user with 24 positive feedback ratings, two neutral ratings, and zero negative ratings. That's an indication the unknown person isn't exaggerating the quality of the data. The megabreach trend is troubling for at least a couple of reasons. First, it demonstrates that service providers are either unable to detect breaches or are willing to keep them secret years after they're discovered. Second, it raises the unsettling question where the trend will end, and if additional breaches are in store before we get there?
