Review: Gigabyte GV-R485OC-1GI Radeon HD 4850 1GB [Guru3D]
We test the Gigabyte GV-R485OC-1GI Radeon HD 4850 equipped with 1GB of DDR3 memory. It has a custom PCB (printed circuit board), comes with no less than 1 Gigabyte of GDDR3 framebuffer (memory), the manufacturer slapped a Zalman cooler on top of it and to finish it off they even overclocked it. It's the stuff we life and breathe for here at Guru3D.com, definitely worth our time checking out. As it turns out, this is one of the best Radeon HD 4850 cards we ever tested.

Intel Core i7 and X58 prices & expected release on 3 November
More news on Intels Core i7 today, as the release date, prices and clock-speeds have leaked.
Core i7 processors (Bloomfield) socket LGA 1366 and the X58 chipset should be released at 3 November for hardware manufacturers and should be available to the consumer 4 weeks later. It is expected that at first the three quad-core Nehalem based CPU's will be released at
In the second quarter 2009 Bloomfield processors will step over the 3.2 GHz frequency, and in the third quarter will appear the more accessible processors LGA 1160.
Processors released will be:
- Core i7 920 2,66GHz
- Core i7 940 2,93 GHz
- Core i7 965 3,2 GHz
Prices, I've also got these for you .. the Core i7 920 will cost 284 USD, the Core i7 940 562 USD and the Core i7 965 which is an Extreme edition BTW, will cost 999 USD. These are prices per 1000 sold processors.
Rumor is that at the end of September a few guys will already receive samples to test .. yet are prohibited to overclock. Intel is supposedly only to allow the expensive processors to be overclocked. Processors under 400 USD will get a bus lock, prohibiting overclocking.
Intel Nehalem PCUs have 130W TDP
According to the fud there are some specs available on nehalem processors. They seem to have a TDP (maximum Wattage) of 130W on all three 2.6, 2.93 and 3.2GHz versions.
Either this is a typo in Intel's official documents that we've seen, or it means that 3.2GHz, which is 600MHz faster than 2.6GHz Nehalem, will have the same TDP.
We've seen the same numbers before, which might indicate that these are the real numbers. The first chips to bear the Core i7 name will be mainstream desktop parts meant for gamers and conventional systems; Intel doesn't allude to the expected 3.2GHz speed but has previously confirmed the new architecture's switch from a front side system bus to point-to-point connections between the processor and peripherals, an on-die memory controller, and Hyperthreading that can at times double the number of effective cores working on a given task at any one time.
Microsoft fires Xbox 360 whistleblower
Robert Delaware, 29, was fired for talking about Xbox 360 failures
"I don't regret it," Delaware said in a phone call to Venture Beat on Thursday. He says it was important to come forward as a game tester to ensure the problem gets corrected.
Delaware worked for Excell Data, a temp agency, but was fired by his Microsoft manager last Wednesday for speaking to Venture Beat, the paper said. As a result of his whistleblowing, he may face civil lawsuits from both his former employer and Microsoft for breach of contract.
"I'll fight it," he said, speaking of possible litigation. "If they want to come after me, bring it on."
Last week, Delaware told Venture Beat in its six-page expose of Xbox 360 defects that Microsoft rushed development of the console to beat PlayStation 3 and Wii to market, resulting in a reported 33 percent failure rate. Microsoft has since increased the original 90 day 360 warranty, first to one year, and later to the current three year extension.

GeForce GTX 260 Core 216 | BFG OCX MaxCORE review [Guru3D]
BFG GeForce GTX 260 OCX MaxCORE test -- NVIDIA was seeking for some more performance in the GTX 260 series, they need to give it a little more bite. And though I'm sure that yet another SKU will drive board-partners crazy, I say bring it on.
NVIDIA today is introducing the GeForce GTX 260 Core 216, this new chip has one additional shader cluster which brings the accumulated number of shader processors towards 216. And it does make a slight difference, yet we'll test the BFG OCX MaxCORE version of it, and boy it does have a lot more bite.

Intel launched its first 6-core processor
Intel launched the Xeon 7400 today. The processor once nicknamed "Dunnington" is the first x86 architecture design to hold six cores and is targeted at very high-end computing where sheer parallelism is more important than clock rate; it's particularly useful for virtual machines and databases, Intel suggests. The chipmaker estimates a speed boost of as much as 50 percent and helps this in part by a similar increase in Level 2 cache to 16MB as well as dedicated virtualization features on the cores themselves.
The processor line tops out at a lower clock speed than quad- or dual-core Xeons and sees the top model reach 2.66GHz with the same 130W of peak power as higher-clocked quad core systems. A 2.4GHz model carries most of the performance but at 90W, while a 2.13GHz entry runs at 65W and is suited to rack servers or other thin servers and workstations. Four quad-core models are also available; the top 2.4GHz version carries the same 16MB of cache as six-core systems and uses 90W of power. The remaining three clock in at 2.13GHz but use cache and power use to determine their speed, with a regular 90W version loading up 12MB of cache, a budget version stripping down to 8MB of cache, and a low-voltage model carrying 12MB but using just 50W of energy.
Intel expects several large-scale PC companies to build systems on the chips, which range in cost from $856 to $2,729 in batches of 1,000. The new Xeons are the last before the transition to the new Core i7 architecture but should result in some of the techniques involved in their design rolled into other processors.
HP updates TouchSmart to 26 inches, Blu-ray
HP updated its TouchSmart all-in-one PCs to push them into high-end home theater territory not covered by earlier models or rivals such as the iMac. The IQ800 series carries a 25.5-inch, 1920x1200 display that converts the touchscreen PC into a near home theater; accordingly, the system comes with a Blu-ray combo drive in one model while all of them have 1080p-capable video and ATSC/NTSC TV tuners. To match the HTPC focus, either system also has new ambient lighting on their chins that either illuminates the wireless keyboard on a desktop or just sets the mood.
The PC builder's custom touchscreen interface is the same as before and streamlines lightweight photo management and editing, music playback, and widgets for weather or other info.
Two models start off the IQ800 line. The IQ804 is built for average use with a 2.16GHz Core 2 Duo, 4GB of RAM, a 500GB hard drive, a DVD burner and a GeForce 9300M GS for video. An IQ816 model adds the Blu-ray combo drive along with a Penryn-era 2.1GHz Core 2 Duo, a larger 750GB hard disk and GeForce 9600M GS video. Wi-Fi over 802.11n provides local networking for every model while either also has a Pocket Media Drive bay to add extra internal storage.
HP starts the IQ800 series at $1,899 and estimates a launch for September 21st. The premium IQ816 boosts the price to $2,099 for an October 21st release.
Guru3D Folding at Home team breaks Top 100 !
It takes a lot of people to do a lot of work, and we surely did that recently as Team Guru3D has entered top 100 in the Folding@home rankings !
It was close to a year ago when team Guru3D joined the folding@Home project for the good cause. At first we had a lot of people donating thei IDLE CPU cycles to the project and recently all the hottie new GPUs from ATI and NVIDIA can be used to compute as well. back then we advanced roughly 40.000 points per day. Wonderful yet currently we average at 170.000-180.000 points per day, amazing. Due to your help we now have entered the Top 100 which is a fantastic achievement.
Guys thank you all so much for helping out in this project !
Now if you have an ATI Radeon series 3000 or newer or GeForce series 8 or newer graphics card and like to help fighting diseases, please join our team, we have Team ID number 69411.
