In 2009-2010, AMD launched the entire 4 chip Evergreen series in 6 months. By previous standards this was a quick pace for a new design, especially since AMD had not previously attempted a 4 chip launch in such a manner. Now in 2012 AMD’s Southern Islands team is hard at work at wrapping up their own launch with new aspirations on quickness. Evergreen may have launched 4 chips in 6 months, but this month AMD will be completing the 3 chip Southern Islands launch in half the time – 3 chips in a mere 3 months.
To that end today AMD is taking the wraps off the final piece of the Southern Islands puzzle: Pitcairn. The middle child of the family, it will be the basis of AMD’s $250+ enthusiast segment Radeon HD 7800 series. We’ve seen AMD capture the high-end with the 7900 series and struggle to control the mainstream market with the 7700 series, but how does the 7800 series fare amidst AMD’s lead in deploying 28nm GPUs ?
Today we will talk about the efficiency and functionality of enhanced liquid-cooling systems from Swiftech that support all contemporary platforms.
Miniature Mini-ITX systems become increasingly popular these days: even in a small form-factor you can easily put together a fully functional system that will be just as powerful as a low-end and sometimes even mainstream full-size computer. Today we would like to introduce to you four Mini-ITX system cases like that from Lian Li and Chenbro.

Both were good if expensive PSUs, and next up on the test bench is a Platinum series that's sold by a brand without their own PSU factory: XFX. They sent us their newest product, the Pro Series 80 Plus Platinum Black Edition, which sets its sights on the high-end of the market. XFX has created an interesting casing with some unusual elements, but we need to find out how good this model actually is.</span></span></p>

As we noted in our Seasonic article, there are various routes to higher efficiency, like removing resistors that may fill other roles. Shunt resistors for example transform some of the power into power loss when current flows through it, since there is a voltage drop. That's actually their job as they measure and prevent overcurrent in an indirect way.On the following pages we will show how XFX reached the requirements for </span>80 Plus Platinum<span style="color: rgb(68, 68, 68); font-family: Arial, Helvetica, sans-serif; line-height: 19px; text-align: left; "> (90%/92%/89% efficiency at 20%/50%/100% load), and we'll also discuss the ODM and how well the XFX model fares in an increasingly crowded market.</span></span></div>

This new mainboard from Asus belongs to the “Republic of Gamers” series for gamers and overclocking enthusiasts. It has excellent set of features, proved to be a great overclocking platform, and the Rampage IV Formula/Battlefield 3 modification also has a free game coupon to sweeten the deal even more.
For every monitor review that I’ve done for AnandTech so far, I know that as soon as I check the comments there will be a thread with the same theme: “I don’t care about 1080p monitors, I only want 16:10 aspect ratios!” When widescreen displays first came out for desktop LCD monitors, virtually every model was a 16:10 display. The 20” Dell I have on my own desk is 16:10, and almost every vendor made 16:10 panels.
As the price of flat panels dropped and HDTV adoption took over, more and more desktop panels migrated to the HDTV aspect ratio of 16:9. The reasons behind this were easy to understand, as you could produce more displays, reuse panels across PC and TV lines, and have a lower cost across the board to let you sell them for less. Most people were more than happy to pay less for a display than to pay 2-3 times as much for those extra 120 pixels at the bottom of a display. As this happened, 16:10 panels became relegated to higher end models, almost always as IPS panels and often with high end features like AdobeRGB colorspace support and more.
Dell finally decided to address this with their U2412M display that features a 1920x1200 on its 24” panel. The U2412M is also an eIPS panel that is natively 6-bit but uses A-FRC to display 16.7 million colors. Dell has managed to bring this monitor in at $329 and can often be found on sale for under $300, while most other 16:10 24” panels come in at $500 or more. What did Dell have to do to hit this aggressive price point? We put the Dell through its paces to find out.

Due to the increased size of the board (in length), the consumer is treated to seven PCIe slots, running at x16/x8/x8/x8 in full quad-GPU mode. This is also alongside some novelty heatsink design in the shape of a Gatling gun for the VRMs and rounds in an open magazine for the chipset. MSI even try and pull a sneaky one in the BIOS settings for better default performance depending on which BIOS you use. </span></p>

In a short time we've seen quite a few companies come out with their first 80 Plus Platinum power supplies. A couple weeks ago we reviewed the Enermax Platimax with 750W, which was a good PSU even though our testing showed slightly less than the advertised efficiency. Enermax also has a 500W Platimax unit, and there are several other brands launching or ready to launch 80 Plus Platinum offerings. Today we'll look at another sample, this time in the form of Seasonic's Platinum Series 860W
One thing that all of the 80 Plus Platinum models have in common is that they are very expensive. Something else to consider is that there are only a limited number of companies that actually manufacture PSUs, building various models according to the specifications their partners request. Seasonic is one such company, and we can expect other brands to use variations of the Seasonic Platinum Series we're reviewing today. The 860W model we're looking at includes two different modes for controlling the fan speed, a fullly modular connector system, and DC-to-DC converters for two of the smaller output voltages. This sounds like another market leader; let's see how it fares under test and whether it can surpass Enermax's competing offerings.
Here's a prickly subject if ever there were one: while with keyboards you could reasonably argue for the superiority of using mechanical switches over traditional rubber-dome membrane keys, mice are much, much more a matter of preference. A mouse could have all the features you're looking for, but if the grip isn't right or the texture makes you hand clammy the whole enterprise can be a bust. Understanding how delicate the balancing act of a good mouse can be, Corsair has come up with matching mice for their new gaming keyboards.
