Sapphire Radeon HD 7950 custom card gets pictured

TechPowerUp came across some photos of a single-fan non-reference Radeon HD 7950 from Sapphire. Clockspeeds are likely the same as the reference board.
The single-fan HD 7950 appears to have a blue-colored PCB that is likely to be AMD's cost-effective reference design. The cooler appears to have a compact heatsink that is cooled by a single central fan. Display outputs include two mini-DisplayPort, and one each of HDMI and DVI. We're also hearing from the source that 900 MHz core with unchanged (1250/5000 MHz) memory will be the maximum factory-OC permitted by AMD to AIB partners. That is not to say that the HD 7950's OC potential beyond that will be limited in any way.

Swiftech Komodo Radeon HD 7970 waterblock revealed

TechPowerUp found pictures of Swiftech's upcoming Komodo full-coverage waterblock for AMD's Radeon HD 7970 graphics card. Pricing and availability is unknown.
Called the Komodo HD 7970, the block confines itself to the size of one expansion slot with an included single-slot bracket. The monolithic black design adds a lot to the aesthetics of the card, including its fittings area. The primary material of the block is nickel-plated copper. The portion of the block over the GPU has a 0.25x0.25 Micro Pin matrix, which maximizes heat dissipation to the coolant. Unlike other full-coverage blocks where a portion of the block that doesn't have flowing coolant makes contact with the VRM, the Komodo HD 7970 has "active" VRM cooling, where the area over the VRM has its own coolant chamber, and is part of the coolant's primary flow.

Intel ships 32nm Sandy Bridge CPUs without GPU

The Tech Report noticed Intel has added three new IGP-less Core i5 processors to its official price list:
The chips come with their GPUs disabled and can be identified by the model numbers 2550K, 2450P, and 2380P. That first CPU features a fully unlocked upper multiplier, so it's the one you'll want.

Versus the existing Core i5-2500K, the 2550K offers 100MHz increases in base and Turbo frequencies, bringing the chip up to 3.4GHz with a 3.8GHz Turbo peak. Those speeds match the Core i7-2600K, which offers additional cache and Hyper-Threading support missing from the i5 series. Intel is selling the 2550K at $225�$92 less than the 2600K and a $9 premium over the 2500K.

Intel Haswell spyshot hits the web

Bit Tech found a photo of a Haswell engineering sample, Intel's 22nm architecture which is slated to be released in 2013.
Based on the the existing Core architecture, Haswell promises numerous improvements over its predecessors. The most interesting of these, and sadly invisible in the leaked picture, is HNI: Haswell New Instructions.

Designed to extend the existing instruction set available in Ivy Bridge, HNI includes Advanced Vector Extensions (AVX) 2 with support for SIMD (Single Instruction, Multiple Data) operations on 256-bit integer data types, bit manipulation instructions for improved handling of variable bitstreams, cryptography, compression and large number arithmetic, gather instructions for vectorising codes with non-adjacent data elements, any-to-any permutes with support for DWORD and QWORD granularity permutes across an entire 256-bit register, vector-vector shifts and floating-point multiply accumulate functionality for boosted floating point performance.

SanDisk began 19nm production in Q4 2011

X-bit Labs reports SanDisk initiated production of 19nm flash memory in Q4 2011:
SanDisk, a leading supplier of NAND flash-based products, said that it had begun production of NAND flash memory using 19nm process technology, as planned, back in Q4. The company actually pins a lot of hopes onto the new type of flash memory and asserts that it will bring better performance, lower cost and even other.

"We began production of 19nm technology in Q4, and it will ramp throughout 2012. As we explained previously, NAND scaling is becoming more complex for the industry, resulting in a lower rate of cost reduction from technology transition. The 19nm technology will generate a lower cost reduction rate compared to what we achieved with the 24nm transition," said Sanjay Mehrotra, chief executive officer of SanDisk, during a conversation with financial analysts.

Five Years With Blu-ray - Part One

Cast your collective minds back to mid 2006. I can't tell you much about that year, other than I'd just turned 20 years old. Wikipedia tells me Saddam Hussein was sentenced to death. Some bad stuff happened. Some good stuff happened. But the contextual relevance of 2006 is this was the year when the high definition formats HD-DVD and Blu-ray were released to the US market.

Despite multiple attempts at amalgamation, talks between the principal backers of Sony and Toshiba had broken down spectacularly and both were working feverishly to bring their products to market first - which was thought to be key to their relative success or failure.

By mid 2006, the first Blu-ray discs had made their way to market, principally from Sony Pictures, including; 50 First Dates, The Fifth Element, Hitch, The House of Flying Daggers, Underworld Evolution, xXx and The Terminator. HD-DVD had beat them to the punch two months earlier by releasing a line-up which included The Last Samurai, Million Dollar Baby, and The Phantom of the Opera, a milestone achieved through that formats initially cheaper manufacturing process and higher yields compared to Blu-ray.

So to Blu-ray was also beaten to the punch with hardware, for some months the only way to play a Blu-ray was through a PC Blu-ray ROM. Toshiba was far more prepared, releasing multiple HD-DVD players to satisfy varying price points. By the end of 2006, Sony had finally caught up with the release of their flagship player, the behemoth BDP-S1 (it weighed some 10 kilograms), but its necessary multiple firmware upgrades following launch, along with unacceptable load times was indicative of the rush to market that would cripple Blu-ray for some time.

Sony's PlayStation 3 fared much better. For some time, this was the white hot hope for Blu-ray's ongoing success, in much the same way that the runaway success of the PlayStation 2 seven years before solidified DVD as the successor to VHS. Whilst the formidable weapon was due to be released worldwide in November 2006, shortages in Blu-ray ROM components forced the delay of the console in Europe and Australasia regions until March 2007. Even so, shortages were commonplace and retailers had to make do with short shipments and even smaller allowances of critical accessories such as the Blu-ray remote control - one of the ways that industry could ascertain how many consumers were purchasing the game system to be used as a Blu-ray player.

Despite some notable public relations faux pas', a wide and damaging internet campaign of hate directed at Sony, an extremely high launch price of $599 USD ($999 AUD) and a newly aggressive Microsoft with the second iteration of the Xbox console, the PlayStation 3 sold well in the lead up to Christmas, which gave Blu-ray backers considerable hope for the future.

By mid 2008 the format wars had reached fever pitch. Microsoft, Intel and HP had thrown their vocal support behind HD-DVD, as did Paramount Pictures who were whisked away from format neutrality by a $150 million dollar deal with Toshiba. Coupled with exclusive studio Universal and favourable behaviour by Warner Brothers, in opposition to Twentieth Century Fox, Sony Pictures and Disney who all exclusively backed Blu-ray. Hundreds of millions of dollars were ploughed into partner support and advertising. Online forums bayed for the blood of the opposing format. But by the end of the year, the cracks were beginning to show. For big box retailers where floor space equals money, it was proving increasingly difficult to support both formats and it came to pass that many including larger players Best Buy and Target dropped support for HD-DVD, as did rental outlets Netflix and Blockbuster.

However, Toshiba was still in the game. Months of preparation was culminating for the annual Consumer Electronics Show in Las Vegas, where Toshiba planned to strike back with a renewed surge against Blu-ray. But like a Judas kiss, the death knell for HD-DVD was delivered by one its staunchest supporters - Warner Brothers. Withdrawing support for the format was the killer blow that HD-DVD could not hope to recover from. Toshiba immediately withdrew from the 2008 CES show with a mere few days notice to decide its next move. A month later it revealed it - effective immediately Toshiba ceased all manufacturing and abandoned the format.

With the battle over, the Blu-ray camp fired on all cylinders. But another battle loomed on the horizon - the rise of downloadable content.

In the second part of the series, I'll discuss the continued impact of the formats rush to market and the struggles (and wins) of the Blu-ray format until today.
