Pushing a 28-core CPU to its limits: 6GHz and beyond

Posted on by
I'm mesmerized by the way liquid-nitrogen vapor flows across the motherboard. There's something oddly therapeutic about extreme overclocking, especially when the cold air gently touches my skin, making even the tiniest bumps in clock speed the...

Apple’s slim MacBook Pro design could be holding back its i9 CPU

Posted on by
The 2018 15-inch MacBook Pro lets you crank up the processor power by swapping in an Intel 2.9GHz six-core Core i9 CPU for an extra $300. But the chip seems to be struggling when it's handling power-hungry tasks, to the point where the average clock...

Overclocking to 7GHz takes more than just liquid nitrogen

Posted on by
Over the years, I've been fascinated by two kinds of events at Computex: eSports and extreme PC overclocking competitions. I doubt I'd ever make it as a professional gamer (I'm more of a Counter Fight kind of guy than a Counter-Strike man these days)...

Intel leak reveals 8-core Haswell-E series desktop CPU for late 2014

Now that Haswell's available in consumer-grade laptops, it's time to look at what's next on Intel's to-do list. A leaked slide-deck is claiming that Haswell-E, the enthusiast version of the chip, is coming in the second half of 2014. The documents also promise that Intel will axe the 4-core base model in favor of 6-and-8-core editions of the CPU, which can pack up to 20MB of L3 cache. At the same time, the company is likely to release the Wellsburg motherboard chipset, which can support DDR4 RAM with a clock speed of up to 2,133MHz. If it's all to be believed, then we have one word of advice to the overclocking community -- best start stocking up on liquid nitrogen.

Visualized: Intel’s Haswell Core i7 overclocked to 6.88GHz on an ASUS motherboard

Visualized ASUS overclocks Intel's Haswell Core i7 to 688GHz

After winning yesterday's Corsair Overclocking competition at Computex, the same folks were brought over to ASUS' ROG event earlier today, where they overclocked an Intel Haswell Core i7-4770K from its typical 3.5GHz to a staggering 6.88GHz -- just a tad less than yesterday's 6.98GHz -- on an ASUS Maximus VI Extreme motherboard. As a bonus, the DRAM frequency was also pushed to 4.1GHz, which is believed to be the fastest yet on Haswell. As usual, the overclockers poured liquid nitrogen onto the chip every now and then to keep it cool, thus giving us the above photo opportunity.

AMD Trinity APU overclocked at 7.3 GHz, kept cool with liquid nitrogen

AMD Trinity APU overclocked at 7.3 GHz, kept cool with liquid nitrogen

AMD's Trinity APUs have only been in the wild for a few days, but some have already taken on the challenge of pushing the new desktop silicon to its limits. By giving the A10-5800K model 1.956 volts, disabling two of its cores and cooling it with liquid nitrogen, overclockers were able to push the chip to 7.3GHz. Air-cooling and 1.616 volts squeezed out 5.1GHz without sacrificing any cores. If you're a mere mortal who's fresh out of liquid nitrogen (or never had any to begin with), you should be able to comfortably bump CPU performance by roughly 10 percent and GPU speeds by 15 to 17 percent. For the full specs on this particular overclock, hit the source links below.

Raspberry Pi’s new turbo mode boosts performance by roughly 50 percent, doesn’t void warranties

Raspberry Pi's new turbo mode boosts performance by roughly 50 percent, doesn't void warranties

Giving a Raspberry Pi extra voltage is a quick way to squeeze out additional processing power and void its warranty, but the folks behind the tinker-friendly board have devised a turbo mode that boosts performance by roughly 50 percent while keeping warranties intact. After studying the effects of temperature and voltage on the hardware's lifespan, the team found that dynamic overclocking and overvolting doesn't affect the Pi's health appreciably. As a result, speeds can be pushed from 700MHz to 1GHz only when additional horsepower is needed, and things are reined back in when the CPU grazes 185 degrees Fahrenheit (85 degrees Celsius). Benchmarks show the extra computing oomph makes the Pi 52 percent faster on integer, 64 percent speedier on floating point and 55 percent snappier on memory tasks. The new mode is available in the latest firmware update, which also includes temperature and frequency widgets, better analog audio, improved USB performance and support for WiFi dongles out of the box. For the technical nitty-gritty and more details on the upgrade, hit the source link below.

Digital Storm unveils X17E gaming laptop, pushes your CPU to 4.5GHz for frenzied fragging

Posted on by

Specialist gaming outfit Digital Storm has busted out its new X17E gaming laptop, designed to keep you entertained without too much grunting. The 17-inch unit comes with a 1,920 x 1,080 display, a choice of GeForce GTX 680M or Radeon 7970M and an Intel Core i7-3910XM, which the company's engineers reckon can be stably overclocked to a whopping 4.5GHz. It's got the usual raft of features you'd expect in a high end unit, including support for 32GB RAM, USB 3.0, eSATA, Blu-Ray and a backlit keyboard you can tweak to your needs. The base model will be out at the end of September, setting you back $1,753, while a signature edition with a custom paint-job will come later, and cost you more.

Google Nexus 7 overclocked to 2GHz, punches well above its weight

Google Nexus 7 overclocked to 2GHz, punches well above its weight

The stock Nexus 7 peaks at a 1.3GHz clock speed when it's at full burn. That's certainly good enough for the $199 price tag, but eager adopters have just hit a new record in trying to wring out even more of a bang for the buck. Courtesy of a custom Elite kernel from XDA-Developers' Clemsyn, the Tegra 3 in the mini tablet will scale all the way to a heady 2GHz. You'd be right in suspecting that it leads to some dramatic speed boosts: the Nexus 7 at this pace can put a Transformer Prime to shame in common benchmarks, let alone most smartphones. Reaching the loftier heights of performance does require nerves of steel, however. The Elite kernel is very much a rough build that the creator doesn't yet trust with the public, and NVIDIA's processor is already known to get toasty under significantly added stress. There's hope a refined kernel will make for a safer venture into unknown territory. If you can't wait to throw at least some caution (and the warranty) to the wind, though, hit the second source link for code that will reach a slightly less melt-prone 1.8GHz.

AMD Radeon HD 7970 could get ‘GHz Edition’, put the hurtz on NVIDIA

AMD Radeon HD 7970 could get 'GHz Edition'

AMD's Radeon HD 7770 and 7870 reference cards already sport 1GHz clock speeds, but so far the high-end flagship 7970 has been stuck at 925MHz. That'd be no big deal, perhaps, were it not for rival NVIDIA's benchmark-stealing GeForce GTX 680, which autonomously adjusts its clock speed on the fly and easily hits 1.2GHz under the right conditions. But while NVIDIA has yet to roll out its full stack of 28nm cards, AMD is finding plenty of time to play catch-up. According to Australian site Atomic MPC, the company has revealed that the manufacturing process of its next-gen GPUs has improved to the point where the same average voltages can yield much higher clock speeds. Recent chips can reach 1.25GHz without struggling, which means a conservative "GHz Edition" of the 7970 can now safely be rolled out, of course with scope for much higher overclocking on third-party boards with more robust coolers. By the time the battle between Red and Green reaches full-swing, it might not be so easy to call a winner.
