While announcements about its existence date back to just over a year, I can tell you this case has been in development since not long after SilverStone released their remarkably strong Temjin TJ08-E. That case's stellar performance surprised even SilverStone; I'm reasonably certain they thought the Fortress FT03 was going to be their strongest Micro-ATX enclosure for some time to come, but the TJ08-E changed the game. After I reviewed it, I asked them directly for an ATX version and received the kind of cagey answer I ultimately wanted to hear.</span></div>
<div><span style="font-size: small;"><br />
</span></div>
<div><span style="font-size: small;">Unfortunately, the journey of the full-sized TJ08-E descendant has been more than a little fraught. It's my understanding that tooling problems, among other things, have led to lengthy delays. In fact even the Raven RV04 will be showing up late on American shores; we'll likely actually get the high end version of this chassis, the Fortress FT04, first.</span></div>
<div><span style="font-size: small;"><br />
</span></div>
<div><span style="font-size: small;">The design has a lot to live up to. SilverStone's Fortress FT02 has practically been the gold standard for air cooling for some time now, and they posit that the FT04 is actually capable of producing even better performance. Part of the reason they have this confidence is because they seem to understand a vital truth about cases and cooling that many of their contemporaries still grapple with: nothing cools better than a direct line of airflow through the CPU cooler. The rotated motherboard and convection cooling was never the magic that made the FT02 and previous Ravens work; it was good marketing and seemed sound, but the reason those cases were so good at their jobs was the fact that they had giant fans blowing directly through the CPU tower coolers. Air wasn't moving at an angle like it does in traditional ATX cases.</span></div>
<div><span style="font-size: small;"><br />
</span></div>
<div><span style="font-size: small;">The Raven RV04 is, in true SilverStone fashion, kind of an oddball. But it's an oddball even by SilverStone standards. What should strike you immediately is the fact that they don't include a 120mm exhaust fan by default, flying in the face of conventional wisdom. This is something actually covered in their press material; by not including the 120mm exhaust fan, they're able to let the extant front intake fans to channel air directly from front to back. The flow of air inside the RV04 winds up being defined almost entirely by the coolers used on the processor and graphics card(s). Ordinarily I pay even less attention to PR than you do, but SilverStone's is usually pretty on the money, and without spoiling too much I can tell you that I definitely didn't miss the exhaust fan.</span></div>

The functionality and features of this mainboard could have been fit for a flagship board of the past, but today it is just enough to place this product in the very mainstream segment, making it the junior model from Asus on Intel Z77 Express chipset. And it is probably the first time that we see wireless support implemented in a far not the top mainboard model like that.
Today we are going to talk about the fastest mass production GeForce GTX TITAN graphics accelerator with air cooling as well as the results of a pair of TITAN cards in a 2-way SLI configuration.
<p><span style="font-size: small;">On the very first monitor review I did for AnandTech, I skipped over the input lag tests. I didn’t have a CRT I could use for a reference, and as someone that isn’t a hard-core gamer themselves, I wasn’t certain how much overlooking them would really be missed. Well, I was wrong, and I heard about it as soon as it was published. Since that initial mistake I’ve added two CRT monitors to the testing stable and tried to find the ideal way to test lag, which I’m still in search of.</span></p>
<p><span style="font-size: small;"> To serve the large, and vocal, community of hard core gamers, there are plenty of monitors out there that directly target them. One such display is the BenQ XL2720T, a 120 Hz LCD that’s also used in many sponsored gaming tournaments. Beyond its gaming pedigree, I was interested to see if it also performed well as a general purpose display, or if it really is just designed for a small subset of the market.</span></p>
<p><span style="font-size: small;"> Probably the key feature on the XL2720T is its 120 Hz refresh rate, which as usual means that it is a TN-panel. The other key feature on it is a quick select switch that it includes to let you switch between monitor presets with a single button press. For their gaming target, BenQ sees you utilizing this to have different presets for different games, and they even provide some specific profiles for popular games that you can load and use for these. Another use would be to use one for daytime settings, one for nighttime, and one for gaming. The quick access to switch modes makes it easy to do so, and providing “optimized” settings for games might be a very beneficial use.</span></p>
<p><span style="font-size: small;"> The included stand for the XL2720T is very well done, with a full range of ergonomic adjustments and you can assemble the whole thing without a single tool. I’d use a screwdriver at the end to make sure it is really tight and secure, but the overall stand design is great. One feature I’d still like to see from a monitor company is inputs that either rotate or are angled at 45 degrees to make it easier to hook up cables than to have to reach underneath. Thankfully since it pivots to vertical, it is still easy to hook up the BenQ XL2720T to your computer or video game system. It has a pair of HDMI ports, so it is well equipped for both PC and console gaming.</span></p>
<p><span style="font-size: small;"> One disappointment is that the USB ports are still just USB 2.0 and not 3.0 as most new, higher end monitors have now. Another disappointment in the monitor design is the touch sensitive buttons that control the on-screen display.</span></p>
<p><span style="font-size: small;"> As with the Dell U3014 that I just reviewed, I find the touch screen buttons to be less responsive than actual buttons, and wish companies would go back to standard buttons. It doesn’t look quite as nice but it is far more functional. This is somewhat alleviated by the S Switch that BenQ includes. Though mostly used to switch between three preset modes, you can also use the wheel to control the OSD, and here it does a great job. The OSD has been redesigned from previous BenQ displays so it is much better to use, with all selections going Up and Down, without any Side-to-Side inputs. This combination is one of the better interfaces that I’ve used; I just wish controlling it without the S Switch worked as well.</span></p>
<p><span style="font-size: small;"> As mentioned, the on screen display from BenQ has been totally redone from the last display that I used. Previously you would move Left to Right to select a category, Up and Down to select a function to adjust, and then Left to Right to adjust it, all with just two buttons to move all four directions. The OSD now resembles the ones that Dell has, where all selections and inputs are Up and Down, making it very easy to adjust the display. It also lets you see all the levels of sub-menus on the screen at once, which makes it easy to see what you are working on and not get lost in the menu system. BenQ has moved from having one of the worst menu systems for user controls to having one of the best that I’ve used. Bravo for that!</span></p>
<p><span style="font-size: small;">On the exterior and the on screen display, BenQ has gotten most everything right with the XL2720T. Sure I would change a couple little things, but they manage to get the overall user experience with the monitor as correct as anyone else has right now, and that’s much different than I said about their displays two years ago. I wish every monitor vendor would take this feedback and improve their products as much as BenQ did in these areas.</span></p>

New Asus graphics accelerator can be called a true apogee of the Radeon HD 7970 evolution. It is hard to believe that there could ever be any faster or more advanced graphics accelerators before the HD 7000-series epoch comes to its logical end.
<p><span style="font-size: small;"> The run up to Computex has been insane. Kabini, Haswell and Iris hit us back to back to back, not to mention all of the travel before receiving those products to get briefed on everything. Needless to say, we're in major catchup mode. There's a lot more that I wanted to do with Haswell desktop that got cut out due to Iris, and much more I wanted to do with Iris that I had to scrap in order to fly out to Computex. I will be picking up where I left off later this month, but with WWDC, Samsung and a couple of NDA'd events later this month, it's not going to be as quick as I'd like.<br />
<br />
One part that arrived while I was in the middle of launch central was AMD's Richland for desktop. Effectively a refresh of Trinity with slightly higher clocks, a software bundle and more sophisticated/aggressive turbo. Richland maintains socket compatibility with Trinity (FM2), so all you should need is a BIOS update to enable support for the chip. AMD sent over two Richland parts just before I left for Computex: the 100W flagship A10-6800K and the 65W A10-6700. I didn't have time to do Richland justice before I left, however I did make sure to test the 6800K in tandem with Haswell's GPU just so I had an idea of how things would stack up going forward as I was writing my Iris Pro conclusion.<br />
<br />
For all intents and purposes, Iris Pro doesn't exist in the desktop space, making Haswell GT2 (HD 4600) the fastest socketed part with discrete graphics that Intel ships today. In our Haswell desktop review I didn't get a chance to really analyze HD 4600 performance, so I thought I'd take this opportunity to refresh the current state of desktop integrated processor graphics. Unlike the staggered CPU/GPU launch of Trinity on the desktop, the situation with Richland is purely a time limitation on my end. This was all I could put together before I left for Computex.<br />
<br />
Although Richland comes with a generational increase in model numbers, the underlying architecture is the same as Trinity. We're still talking about Piledriver modules and a Cayman derived GPU. It won't be until Kaveri that we see GCN based processor graphics from AMD at this price segment (Kabini is already there).<br />
<br />
As Jarred outlined in his launch post on Richland, the 6800K features 4 - 8% higher CPU clocks and a 5% increase in GPU clocks compared to its predecessor. With improved Turbo Core management, AMD expects longer residency at max turbo frequencies but you shouldn't expect substantial differences in performance on the GPU side. The A10-6800K also includes official support for DDR3-2133. AMD is proud of its valiation on the A10-6800K, any parts that won't pass at DDR3-2133 are demoted to lower end SKUs. I never spent a ton of time testing memory overclocking with Trinity, but my A10-5800K sample had no issues running at DDR3-2133 either. I couldn't get DDR3-2400 working reliably however.<br />
<br />
or my Richland test platform I used the same Gigabyte UD4 Socket-FM2 motherboard I used for our desktop Trinity review, simply updated to the latest firmware release. I ran both AMD platforms using the same Catalyst 13.6 driver with the same DDR3-2133 memory frequency. AMD was quick to point out that only the A10-6800K ships with official DDR3-2133 support, so the gap in performance between it and Trinity may be even larger if the latter tops out at DDR3-1866. The HD 4000/4600 numbers are borrowed from my Iris Pro review using DDR3-2400, however I didn't notice scaling on Haswell GT2 beyond DDR3-1866. </span></p>

</span></p>
<p><span style="font-size: small;">AMD decided to refresh their Socket FM2 platform and release a new generation of hybrid processors for it based on Richland design. This is exactly the one that earned the “Elite Performance APU Platform” title in the mobile segment.</span></p>

This is a very volatile time for Intel. In an ARM-less vacuum, Intel’s Haswell architecture would likely be the most amazing thing to happen to the tech industry in years. In mobile Haswell is slated to bring about the single largest improvement in battery life in Intel history. In graphics, Haswell completely redefines the expectations for processor graphics. There are even some versions that come with an on-package 128MB L4 cache. And on the desktop, Haswell is the epitome of polish and evolution of the Core microprocessor architecture. Everything is better, faster and more efficient.
There’s very little to complain about with Haswell. Sure, the days of insane overclocks without touching voltage knobs are long gone. With any mobile-first, power optimized architecture, any excess frequency at default voltages is viewed as wasted power. So Haswell won’t overclock any better than Ivy Bridge, at least without exotic cooling.
You could also complain that, for a tock, the CPU performance gains aren’t large enough. Intel promised 5 - 15% gains over Ivy Bridge at the same frequencies, and most of my tests agree with that. It’s still forward progress, without substantial increases in power consumption, but it’s not revolutionary. We compare the rest of the industry to Intel’s excellent single threaded performance and generally come away disappointed. The downside to being on the top is that virtually all improvements appear incremental.
The fact of the matter is that the most exciting implementations of Haswell exist outside of the desktop parts. Big gains in battery life, power consumption and even a broadening of the types of form factors the Core family of processors will fit into all apply elsewhere. Over the coming weeks and months we’ll be seeing lots of that, but today, at least in this article, the focus is on the desktop.
After a very long and anxious wait we can finally take a close look at one of the fourth generation Core processors for desktops, which is based on the new Haswell microarchitecture. Significantly higher performance, better energy-efficiency, excellent overclocking – all this isn’t the case. What happened?
As many as seven heatpipes, dual-array heatsink, two fans – will the new GELID cooler become a super-cooler today? Let’s find out.
