fMRI Data Reveals the Number of Parallel Processes Running in the Brain

Submitted by: Hologram @ 03:15 AM | Sunday, November 9, 2014 | (url: http://www.techno...)

The human brain carries out many tasks at the same time, but how many? Now fMRI data has revealed just how parallel gray matter is. ... Although the analysis is complex, the outcome is simple to state. Georgiou says independent component analysis reveals that about 50 independent processes are at work in human brains performing the complex visuo-motor tasks of indicating the presence of green and red boxes. However, the brain uses fewer processes when carrying out simple tasks, like visual recognition.

That's a fascinating result that has important implications for the way computer scientists should design chips intended to mimic human performance. It implies that parallelism in the brain does not occur on the level of individual neurons but on a much higher structural and functional level, and that there are about 50 of these. 'This means that, in theory, an artificial equivalent of a brain-like cognitive structure may not require a massively parallel architecture at the level of single neurons, but rather a properly designed set of limited processes that run in parallel on a much lower scale,' he concludes.


Best CPU Cooler Performance - Q4 2008

Submitted by: Das Capitolin @ 01:37 PM | Tuesday, January 6, 2009 | (url: http://benchmarkr...)

From my experience, 2008 has been a very good year for CPU coolers. We've tested the OCZ Vendetta 2 to perform as well or better than coolers twice its price, and we've discovered that the Thermaltake V14 Pro can deliver top cooling performance while looking good. But heading into 2009 we must bid farewell to the LGA775 platform, which has been the home to many of our most popular products, and welcome in the new LGA1366 socket for the Intel Core i7 CPU & X58 platform. This Best CPU Cooler Performance - Q4 2008 article will be the last foreseeable socket T series round-up from Benchmark Reviews, unless something really big changes the landscape.


Intel Core i7 CPU & DX58SO X58 Platform

Submitted by: Das Capitolin @ 09:06 PM | Sunday, November 2, 2008 | (url: http://benchmarkr...)

In today's segment we will cover an overview of the technological aspects of the Core i7 processor series and the X58 motherboard that supports it. We'll test all three of the processors using a succinct series of benchmarks run a stock processor speeds and draw the necessary conclusions from their results. What else is left you might ask? Believe me when I say that's only scratching the surface. In future reviews we'll concentrate on individual product components and expound in much greater detail on that product's performance capabilities including overclocking.


Best CPU Cooler Performance - Q3 2008

Submitted by: Das Capitolin @ 06:16 PM | Friday, October 10, 2008 | (url: http://benchmarkr...)

When it comes down to it, consumers that shop for aftermarket cooling products only want one thing: the very best their money can buy. It makes perfect sense, too. Since so many products flood the market every day, it all comes down to price and performance. Based on this principal, Benchmark Reviews searches out the latest CPU coolers and tests them under real-world overclocked conditions. Want to know which cooling products stand-out? This quarterly update to our Best CPU Cooler Performance series will separate the good from the bad.


Best CPU Cooler Performance - Q2 2008

Submitted by: Das Capitolin @ 05:37 PM | Friday, July 18, 2008 | (url: http://benchmarkr...)

Benchmark Reviews strives to offer the overclocker and hardware enthusiast community solid evidence reflecting the true performance of computer products through rigorous testing and evaluation. The purpose of this second article of our series is to document performance and declare the best CPU coolers available as of Q2 2008.


Vendetta 2 vs TRUE vs HDT-S1283

Submitted by: Das Capitolin @ 11:02 AM | Tuesday, June 10, 2008 | (url: http://benchmarkr...)

This article serves only one purpose: test three of the industry's most coveted coolers. Not very long ago Benchmark Reviews published the article Best CPU Cooler Performance - Q1 2008. At the time, the effort we gave in producing our test results seemed well worth the trouble. However, months later we see that there's a lot more to a cooler than just measuring performance with the same common fan. So after even more testing, we now have a full understanding of each CPU coolers individual characteristics and deliver the results to you. Benchmark Reviews is proud to present a three-way fight to the finish: The OCZ Vendetta 2 vs. Thermalright's Ultra-120 eXtreme vs. Xigmatek's HDT-S1283.

Xigmatek Achilles S1284 HDT CPU Cooler

Submitted by: Das Capitolin @ 01:00 PM | Wednesday, May 7, 2008 | (url: http://benchmarkr...)

Xigmatek has really made a name for themselves over the past year thanks to the Heat-pipe Direct Touch technology that they have embraced. When Benchmark Reviews originally reviewed the HDT-S1283 cooler we were absolutely astonished by the incredible results. Once again, we are the very first to test the newest hardware, and you'll be impressed to know that this product delivers the performance needed by overclockers while fulfilling the enthusiasts wish list for attractive features. Benchmark Reviews introduces the Xigmatek Achilles S1284 HDT CPU Cooler CAC-SXHH4-U02 and tests the performance against the top competitors.

Intel Unveils 16 New Processors

Submitted by: KnightMare @ 05:34 AM | Tuesday, January 8, 2008 | (url: http://enthusiast...)

For those of you wondering just what Intel had up its sleeve for the new year, we can tell you this, the company just unveiled sixteen new processors. The good news today is that there is a processor for just about everyone on the list, from the Core2 Duo to the Core 2 Duo Extreme with everything in between (quad core Xeons).


While it seems only yesterday that 65nm process got to the enthusiast, Intel is today telling us about very affordable 45nm processors that are ready to come to market.

AMD made greater gains than originally thought

Submitted by: KnightMare @ 11:59 AM | Wednesday, September 12, 2007 | (url: http://www.digiti...)

iSuppli's final estimate of CPU market share in the second quarter reveals that AMD made greater gains than originally thought.

AMD in the second quarter of 2007 gained 2.5 percentage points compared to the first quarter to take a 13.4% share of overall CPU revenues.

The overall CPU market consists of RISC and general-purpose devices, as well as the x86-type chips for PCs sold by AMD and rival Intel.

Meanwhile, Intel in the second quarter suffered a two percentage point decrease in revenues share, giving it a still-commanding 78.8% portion of the market.

This was far greater than the preliminary 0.5% increase for Intel and the 0.5% increase for AMD iSuppli estimated in July.
