NZXT isn’t the only company branching into CPU coolers. EVGA—better known for videocards and motherboards—recently released its Superclock cooler, with five direct-contact copper heat pipes, one clear 12cm fan with red LEDs, and a sharp-looking black finish to its skyscraper-style copper cooling fin stack.
At $50, the Superclock is around the midpoint of CPU cooler prices, but can its performance live up to its name?
We have to hand it to Thermaltake: Nearly everything about the Frio OCK is well thought out. The two 13cm fans are secured in a black, red, and blue cowling that clips on and off of the heatsink with ease, eliminating many of the installation frustrations inherent in two-fan (or one-fan) heatsinks. Are the Frio OCK's performance numbers as cool as its design?
NZXT is new to the cooler game, but if the Havik 140 is any indication, the company isn’t being dumb about it. The Havik 140 is a hefty cooler in the stacked-fins “skyscraper” style, with six copper heat pipes rising from the heat exchanger through 4.25 inches of nickel-plated‑copper heat-dissipation fins.
Once mounted, the Havik performed admirably, besting the Hyper 212 Plus in our stress test by nearly 18 degrees Celsius, but was it good enough to dethrone the Best of the Best?
Now that both AMD and Nvidia have dual-GPU videocards on the market, quad-GPU CrossFireX and SLI setups are possible—that is, if you have the motherboard, the power supply, the money, and can actually find two dual-GPU cards.
Representing quad SLI, we have two relatively compact Nvidia GeForce GTX 590s. In the quad-CrossFireX corner are two of AMD's hulking, foot-long Radeon HD 6990s. Both paris cost about the same—an astronomical $1,500, give or take—but which is the better option?
OCZ just keeps pushing the envelope on its PCI Express SSDs. The first RevoDrive contained two 60GB SF-1200-powered SSDs in RAID 0, with a Silicon Image PCI-to-SATA controller. The RevoDrive X2 kept the same architecture, but added a second PCB with two additional controllers and two more 60GB sets of NAND. OCZ’s RevoDrive3 X2 updates the platform to second-generation SandForce, but the new SSD controller isn’t the only change.
Not many of us could convince our bosses that we’re most efficient when working slowly. But then, we aren’t microprocessors. For decades, researchers have known that processors achieve peak energy efficiency when their transistors operate at very low voltages near the threshold between their on and off states.
The technology is called near-threshold voltage (NTV) computing and it could be Intel's trump card in the power saving game.
Imagine a graphics card weighing 5.25 pounds with three (yes, three) 8-pin PCI Express power connectors. Now imagine this card taking up three PCI Express slots and almost sucking the life out of an 850W power supply.
That may be one reason Asus named this card after the Roman god of war. It's probably the most powerful single graphics card we've tested, but that power comes at a substantial cost. You'll need the right type of motherboard and case, too—one where you can install a three-slot-wide card that's 12.25 inches long and 5 inches tall.
It’s easy to become jaded when you review as much cutting-edge hardware as we do. We try not to be curmudgeons, but we do get grumpy when next-gen hardware fails to make a leap in performance—or worse, when it falls behind the gear it’s intended to supplant. So we’re happy to report that benchmarking Netgear’s new WNDR4500 left us grinning from ear to ear. This is the fastest router we’ve ever tested, and it’s packed with new features.
Belkin’s N750 DB offers a better-than-average feature set, but the router’s performance is a mixed bag. At most of our test stations, it delivered very good performance from its 5GHz radio but mediocre throughput from its 2.4GHz radio. Belkin arrives at the N750 model number by adding the 300Mb/s theoretical throughput on its 2.4GHz radio to the 450Mb/s theoretical throughput of its 5GHz radio. This is nonsense, of course, because you can’t bond the two together to achieve throughput that even approaches 750Mb/s.
D-Link markets this single-band (2.4GHz) router as particularly well suited for gaming and media streaming, and it is endowed with very good quality-of-service features, but QoS can’t magically render the 2.4GHz frequency band any less crowded. And given our relatively pristine test environment, the best word to describe the DIR-657’s range and TCP throughput is pathetic.
