Qualcomm teases 28nm dual-core Snapdragons, pixel-punching Adreno 300 GPU
by admin on Nov.18, 2010, under Handheld Devices, Tech News

By the time Qualcomm’s 1.5GHz QSD8672 Snapdragon finally makes it to market, it might be obsolete — the company just announced that the new 28nm dual-core MSM8960 system-on-a-chip will have five times the performance and consume 75 percent less power than the original Snapdragon when it arrives in 2011. It’s got the usual WiFi, GPS, Bluetooth and FM radio modules but also a multi-mode LTE / 3G modem too, and reportedly four times the graphical muscle on board. Speaking of graphics, Qualcomm seperately took the time to detail a new GPU: the Qualcomm Adreno 300 series, which will allegedly offer the gaming performance of an Xbox 360 or PS3. We’d say “We’ll believe it when we see it,” but that would imply doubt — the reality is that we just want to feast our eyes on mobile gaming bliss as soon as humanly possible.

GPU Processing and Password Cracking !
by admin on Sep.28, 2010, under Tech News

Recently, research students at Georgia Tech released a report outlining the dangers that GPUs pose to the current state of password security. There are a number of ways to crack a password, all with their different pros and cons, but when it comes down to it, the limiting factor in all of these methods is processing complexity. The more operations that need to be run, the longer it takes, and the less useful each tool is for cracking passwords. In the past, most recommendations for password security revolved around making sure your password wasn’t something predictable, such as “password” or your birthday. With today’s (and tomorrows) GPUs, this may no longer be enough.
Although the article never mentions them by name, the newest tools in password cracking are based around two tools, nVidia’s CUDA and AMD’s Stream SDKs. These tools allow programs to be written in C that can be broken up and utilize the parallel nature of the hardware that is usually optimized for graphics. GPUs are much better at large-scale mathematical operations than CPUs because of this parallel layout. Chances are, if you have a somewhat recent graphics card, it is probably compatible with either CUDA or Stream, and if you already know C, you have all the tools necessary to get started.
The lesson to learn here, the longer or more complex a password is, generally the safer it is. Because of this, a number of tools, both software and hardware, may become more and more popular, or necessary, to accommodate this need.

AMD Kills ATI Branding !!!!
by admin on Aug.30, 2010, under Tech News
Yep, the rumors are true. AMD does indeed intend to do away with the ATI name, eliminating the “ATI Radeon” co-branding the company has steadfastly maintained since its acquisition of ATI. The firm briefed us on its plans late last week and explained several factors influencing its decision.
As one might expect, a major motivator is the fact AMD plans to introduce a range of new products incorporating both AMD microprocessor technology and a Radeon graphics tech on the same chip. The first fruits of the CPU-GPU “Fusion” initiative are slated to arrive soon. “Ontario,” which will combine two copies of the low-power “Bobcat” CPU core with Radeon graphics, is slated to ship before the end of the year. The more powerful “Llano” APU, which mates quad Phenom II-class CPU cores with presumably a more capable GPU, is scheduled for the first half of 2011. Obviously, the combination of the firm’s CPU and GPU technologies into single-chip products could create some consumer confusion, if folks were to continue to think of AMD and ATI as separate entities—especially if the ensuing marketing messages emphasize the benefits of CPU-GPU integration.
Furthermore, AMD tells us it feels confident in making this change right now because its graphics business is “on a roll,” having surpassed rival Nvidia in discrete graphics shipments last quarter, according to analyst estimates, and having secured high-profile design wins with the likes of Apple. Also, the chastening of Intel via its settlement with the FTC gave AMD some extra assurance that the expansion of its brand into graphics wouldn’t hurt its relationships with major PC makers.
Of course, such decisions aren’t made without market research, and AMD shared a snippet of its internal research on this topic with us. We think it’s worth relaying verbatim, in the form of a handsome corporate PowerPoint slide:

The long and short of it is that, according to AMD’s own survey results, consumers savvy enough to know something about discrete graphics cards tend to know the Radeon name, they tend to like AMD, and they don’t mind seeing the AMD name on graphics cards once they realize AMD merged with ATI. The folks at AMD read those results as “permission” to jettison the ATI brand name.

The plan, then, is to replace “ATI Radeon” and “ATI FirePro” with “Radeon” and “FirePro”, along with a sprinkling of AMD corporate identity. The badges you see above will be used for systems with discrete Radeon and FirePro graphics cards. The lower row omits the AMD logo, so PC makers shipping Intel-based systems will be able to avoid the oil-and-water combo of Intel and AMD branding, if they wish.
If you just bought an “ATI Radeon” and are proud of that fact, fear not. Existing products, including the Radeon HD 5000 series, will not be renamed. Instead, AMD says the first products to carry the “AMD Radeon” label will be introduced later this year.
The first “Fusion” APUs will participate in the radically simplified “Vision” branding that AMD introduced last fall. That program, when introduced, consolidated a ridiculous constellation of separate badges and stickers for pre-built PCs and laptops into a much smaller number. AMD apparently intends to further consolidate under the Vision banner going forward, although those badges seem to multiply like guppies, so we wouldn’t place any large bets on things getting straightforwardly simpler. For one example, look no further than the “ATI Eyefinity” technology; that will be re-branded as “AMD Eyefinity” and otherwise kept intact.
Interestingly enough, the corporate “Fusion” branding program will be coming to an end, as well. The Fusion name apparently won’t carry over into APUs, believe it or not.

DARPA enlists NVIDIA to build exascale supercomputer that’s ‘1000x faster’ than today’s quickest
by admin on Aug.11, 2010, under High End Tech
At this point, it’s pretty obvious that GPUs will soon be playing a huge role in modern day supercomputers — a role that may just rival that of the tried-and-true CPU. Virginia Tech is gleefully accepting $2 million in order to build a GPU and CPU-enabled HokieSpeed supercomputer, and today DARPA is handing out $25 million to NVIDIA in order to develop “high-performance GPU computing systems.” Specifically the Defense Department’s research and development arm is aiming to address a so-called “crisis in computing,” and if all goes well, the four-year project will eventually yield a “new class of exascale supercomputers which will be 1,000-times more powerful than today’s fastest supercomputers.” That’s a pretty lofty goal, but NVIDIA will be aided by Cray, Oak Ridge National Laboratory and a half-dozen US universities along the way. And yeah, if ever anyone’s ego was prepared to topple Moore’s Law, it’d be this guy.By Engadget
ASUS Mars 2 teases superpowered dual GeForce GTX 480 goodness
by admin on Jul.19, 2010, under Tech News
We’ll be honest with you, we thought the GTX 480 was finally a graphics core too damn large and power-hungry to get the dual-GPU treatment. ASUS, however, is making us think again. Imagery has emerged of a Mars 2 (or II, if you’re into outdated numbering schemes) reference board that fits two 480s on its densely populated surface, and is fed by not one, not two, but three 8-pin auxiliary power connectors. Back when Galaxy showed off a dual-GTX 470 prototype at Computex a month ago, we deemed it an unreasonable proposition — in terms of power draw, heat dissipation, and cost — but apparently those Taiwanese focus groups are really into their extravagantly overpowered video cards. We suspect if and when this Mars 2 hits retail it’ll do so in a highly exclusive fashion, like its predecessor, and anticipate the unveiling of its cooler — which is likely to be either the biggest or best engineered one we’ve seen yet.

Cost of Computing : The History !
by admin on May.28, 2010, under High End Tech

The following is a list of examples of computers that demonstrates how performance has increased drastically and price has decreased drastically. The “cost per GFLOPS” is the cost for a set of hardware that would theoretically operate at one billion floating point operations per second. During the era when no single computation platform was able to achieve one GFLOPS, this table lists the total cost for multiple instances of a fast computation platform whose speed sums to one GFLOPS. Otherwise, the least expensive computing platform able to achieve one GFLOPS is listed.
Here is the history of computing price :
In 1967 1 GFLOPS cost you $1.1 trillion !
In 1984 1 GFLOPS cost you US$15,000,000 by Cray X-MP Tech !
In 1997 1 GFLOPS cost you $ 30,000 with Two 16-processor Beowulf clusters with Pentium Pro microprocessors
Nowadays computing 1GFLOPS cost you only 0.13$ by ATI technology ( Series 5 e.g ATI 5970 HD )
And the story continues …

World Fastest Notebook GPU !
by admin on May.25, 2010, under Tech News

NVIDIA has just announced that the GTX 480M, the mobile re-spin of its extravagantly overpowered Fermi desktop parts, will be arriving in the middle of next month. Touted as the world’s fastest mobile graphics processor, this chip will bring 352 CUDA cores and a 256-bit memory interface to up to 2GB of GDDR5 RAM. These are clear and convincing advances over the incumbent Green Team leader, the 360M, but things start to look a little worrying when we check the 480M’s clock speeds. The processor speed is nearly halved from the desktop GTX 480, at 850MHz, the memory does only 1,200MHz, and the graphics run at 425MHz — we didn’t know anything worthwhile even operated below 500MHz these days. Either way, you’re getting a computing powerhouse, with the 480M’s 897 gigaflops comfortably dwarfing its predecessor’s 413 and promising almighty tessellation performance. What it all means with regard to keeping your frame rates up while traversing the Terminus Systems, we can’t yet say. We’ll let the benchmarking gurus figure it out — go past the break for the full press release and spec sheet.
