Users: 0Guests: 195Total: 195Nvidia GeForce 400 family that is slowly becoming history has never got a high-end dual-processor model. Maybe it is destined to be born in GeForce 500 family, and today we will try to find out what we could potentially expect from a hypothetical graphics accelerator with two GF110 onboard.
Intel has jut started selling new LGA1156 processors with Sandy Bridge microarchitecture. We tested a few most interesting new offerings, which will be conquering the mainstream price segment.
<p><span style="font-size: small;">If there's one thing I've learned doing display reviews, it's that the 30-inch segment represents (as it should) the best of the best. Entries here have the most input options, features, best panels, and the highest resolution you can get for the money. It's a breath of fresh air to play with a real 16:10, 2560x1600 display after toying with 1080P monotony for so long. If the displays industry worked anything like the CPU industry, we'd have 300 PPI displays with no response lag, infinite contrast, and all for way less than we're paying now. If there was a new year's resolution display manufacturers should make, it's that they stop making 1080P panels in 2011. <br />
</span></p>
<p style="text-align: left;"><span style="font-size: small;"> Anyhow, today we're talking about the Dell U3011. I got the chance to review HP's 30 inch monitor, the ZR30w, back when it launched, and will use it as a mental comparison. The Dell U3011 is a refresh of the Dell U3008WFP, and brings a 10-bit per color panel with 12-bit internal processing, more input options, factory calibration (more on that later), and is supposedly 1 ms faster in the response time department. <br />

Opinions vary as to what an ideal keyboard should be like. Logitech makes another attempt to win the hearts of those who prefer wireless devices.
he year 2011 is most likely to be a defining year of the personal technology industry. X-bit labs believes that in 2011 the war between ARM and x86 will officially start, the market of tablet PCs will skyrocket, Google Android will become the most popular operating system for smartphones and overclocking stereo-3D will become a "free" feature on premium HDTVs. In addition, the beginning of the APU era will blur the lines between netbooks and notebooks, whereas Intel's Sandy Bridge will change the approach to CPU overclocking forever.
This roundup will talk about new hard disk drives models that came out in second half of 2010. We will discuss 15 HDDs from Hitachi, Samsung and Western Digital.
<p><span style="font-size: small; ">Just four months ago, NVIDIA released their </span><span style="font-size: small; ">top-to-bottom 400M lineup</span><span style="font-size: small; ">.Since the announcement, it took about a month but we then got the ASUS G73Jw (460M), Dell XPS L501x (420M), Clevo B5130M (425M), and ASUS N53JF (425M) in rapid succession. All of these were decent offerings, with a nice blend of performance and features at reasonable prices. Of course, Core 2010 products are last year’s news, and with the launch of Sandy Bridge the whole industry is moving to 2<sup>nd</sup> Generation Intel Core Processors (aka Core 2011). With an improved IGP threatening low-end discrete GPUs, what better time for NVIDIA to refresh their mobile parts?</span></p>
<p><span style="font-size: small; ">Unlike the desktop GTX 580, the new 500M mobile parts are all using existing architectures; there are even a couple of new 400M parts to round things out. The major change is that we’re getting higher clock speeds, both on the GPU cores/shaders as well as the memory. In a few cases we also have additional shaders available, as well as clearing up some potentially confusing part names (really!). Read on for details on this year’s NVIDIA laptop offerings—coming soon to a Sandy Bridge laptop near you !</span></p>

Back in August 2010, AnandTech published its Sandy Bridge preview—an in-depth examination designed to tantalize consumers and industry alike as to what Intel’s latest production has to offer. I would like to review some of the major points as an introduction to the platform.
As you would expect, the new socket 1155 processors are incompatible with socket 1156 motherboards. The new motherboards will come in H and P varieties, with the H series taking advantage of the graphics on the processor die, whereas the P series will utilize discrete graphics only. At launch, both P67 and H67 chipsets will be available, with the H61 chipset released during Q1 2011.
Despite losing the on-chip graphics with the P series, these boards will support dual PCIe lanes running at x8 speed. The PCIe lane bandwidth of the new chipset is double that of previous Intel chipsets, firstly to increase correlation with chipsets, but also to help support SATA 6 Gb/s which runs over PCIe 1x, and future movement into USB 3.0.
The P/H67 chipsets will natively support two SATA 6Gb/s ports, with the possibility of some manufacturers adding an NEC/Marvell/Etron chip to increase this to four. Four SATA 3Gb/s will be included as standard. No USB 3.0 native support is included, much to the disappointment of some consumers, but again manufacturers at their own discretion can add an chip to give a couple of ports in the back panel, or a few more through onboard headers. USB 2.0 is provided copiously, with at least 10 ports available across the range, through either the back panel or onboard headers.
<p><span style="font-size: small;"> Intel never quite reached 4GHz with the Pentium 4. Despite being on a dedicated quest for gigahertz the company stopped short and the best we ever got was 3.8GHz. Within a year the clock (no pun intended) was reset and we were all running Core 2 Duos at under 3GHz. With each subsequent generation Intel inched those clock speeds higher, but preferred to gain performance through efficiency rather than frequency.</span></p>
<p><span style="font-size: small;"> Today, Intel quietly finishes what it started nearly a decade ago. When running a single threaded application, the Core i7-2600K will power gate three of its four cores and turbo the fourth core as high as 4.1GHz. Even with two cores active, the 32nm chip can run them both up to 4GHz. Mission complete.</span></p>

You’re probably sick of me talking about Sandy Bridge in our notebook reviews, particularly since up to now I’ve been unable to provide any numbers for actual performance. Today, Intel takes the wraps off of Mobile Sandy Bridge and I can finally talk specifics. Notebooks have always been substantially slower than desktops, and prices for a set level of performance have been higher; that’s not going to change with the SNB launch, but the gap just got a lot narrower for a lot of users. The key ingredients consist of higher core clocks with substantially higher Turbo modes, an integrated graphics chip that more than doubles the previous generation (also with aggressive Turbo modes), and some additional architectural sauce to liven things up.
