Broadcom introduces three new 802.11 Wi-Fi chips aimed at the PC and set-top box market

For most of the last year, Broadcom has focus all of his efforts on creating chips for the high-end and low-end mobile phone and tablet market. This morning, the company has announced three new Wi-Fi 802.11ac chips that are aimed at the PC and set-top box market.

The company has just released the BCM4350, BCM43556, as well as the BCM43558 which all feature the more robust 2 X 2 MIMO antenna that is capable of hitting speeds of up to 866 Mbps. The chips also able to optimize traffic through a process called beamforming.

 

Broadcom says that the differences in the three chips revolve around everything but the Wi-Fi, with the BCM4350 featuring a more PC friendly set of interfaces that include Bluetooth 4.0, PCI express, and SDIO 3.0. The BCM43558 drops the PCI express and SDIO in favor of USB 3.0. Finally the BCM43556 ditches Bluetooth making it the least featured chip in the lineup.

Haswell and USB 3.0 seeing big issues with USB drives

Intel have officially launched their new Haswell processors, something you can read about in our review. Something a little more interesting though, which comes from Hardware.info in the Netherlands, is that Haswell is seeing issues with USB 3.0.

 

TweakTown image news/3/0/30730_03_haswell_and_usb_3_0_seeing_big_issues_with_usb_drives.jpg

 

They've done some very, very extensive testing and confirmed there are USB 3.0 issues with the 8-series chipset. They tested 22 USB 3.0 drives, with 14 of them experiencing issues and were unable to stay connected when a Haswell system woke back up from standby. Hardware.info have an insane round up of 33 Haswell-based motherboards if you'd like to do some weekend reading!

AMD launches new x86 chips aimed at the microserver market

AMD has just launched a new line of new super low-power processors that are aimed at the NAS and microserver markets. The quad-core and dual-core processors, code-named Kyoto, are designed for high density servers where computer makers try to jam as many processors in a small amount of space as possible.

 

TweakTown image news/3/0/30668_1_amd_launches_new_x86_chips_aimed_at_the_microserver_market.jpg

 

The new processors include the Opteron X2150 which is the quad-core variant which consumes about 11 watts of power while the Opteron X1150 features dual cores and consumes about 9 watts of power. Both processors are clocked at 2GHz and are said to run faster than similar Intel Atom processors.

 

A spokesperson for AMD said:

 

The data center is at an inflection point and requires a high number of cores in a dense form factor with integrated graphics, massive amounts of DRAM and unprecedented power efficiency to keep up with the pace of innovation of Internet services. AMD has a proud history of server innovation, and the AMD Opteron X-Series processors challenge the status quo by providing unmatched capabilities to drive the most energy-efficient servers in the industry.

Intel says that Haswell-based notebooks will provide 50% more battery than Ivy Bridge-based counterparts

Intel are just days away from launching their fourth-generation Core processors otherwise known as 'Haswell', and now they're teasing the world by stating that Haswell-based notebooks will offer 50% more battery life than Ivy Bridge-based counterparts.

 

TweakTown image news/3/0/30576_02_intel_says_that_haswell_based_notebooks_will_provide_50_more_battery_than_ivy_bridge_based_counterparts.jpg

 

Haswell CPU's were designed with mobile devices in mind, with one of their core focuses being lower power consumption, according to Corporate Vice President and General Manager of the Intel Architecture Group, Rani Borkar, when speaking in a media briefing. Longer battery life also will not be coming at the cost of lowered performance, as in idle or standby mode, Haswell chips will do even better, extending battery life to something like 20 times what Ivy Bridge products can offer.

 

The big question here is, is this enough for consumers to get back into PCs again? Smartphone and tablet sales have no signs of stopping, while PC sales are moving backwards, let's hope this ignites a fire under consumers' feet.

AMD confirms they helped Microsoft design the 'semi-custom single-chip' APU that powers the Xbox One

We've been hearing so much about the Xbox One this week, but now we have confirmation from AMD that they are the ones that helped Microsoft design the "semi-custom single-chip" APU that powers the next-gen Xbox One.

 

TweakTown image news/3/0/30552_09_amd_confirms_they_helped_microsoft_design_the_semi_custom_single_chip_apu_powers_the_xbox_one.jpg

 

The Xbox One features an APU that includes an 8-core processor, GPU and 8GB of RAM on the single-chip. The GPU on the Xbox One is still shrouded in mystery, and is definitely a strange move by Microsoft considering how open Sony are about the specifications on the PlayStation 4.

Intel Core i7 4770K reaches eBay

If you can't wait a couple of more weeks for Intel to launch their fourth-generation Core platform, aka Haswell, then you might want to bust out your plastic and check out this eBay link to an Intel Core i7 4770K.

 

TweakTown image news/3/0/30456_05_intel_core_i7_4770k_reaches_ebay.jpg

 

The seller lists that it is boxed and new, and is definitely no the Core i7 3770K or the 3930K, but the 'new generation' Core processor. The buy it now price is just $600, and I do say 'just' because at this price you'd be one of the first in the world with the 4770K in your hands. The seller is 'away' and won't be able to ship the processor itself until May 23, just in case you were wondering.

Intel Core i7 4770K overclocked to 5GHz on just 0.9V of power

Intel is close to launching Haswell, and we're starting to see some validations sent in through CPU-Z, with some interesting results. The first of which is a Core i7 4770K clocked to 5GHz.

 

TweakTown image news/3/0/30292_01_intel_core_i7_4770k_overclocked_to_5ghz_on_just_0_9v_of_power.png

 

The Intel Core i7 4770K was clocked to 5GHz using just 0.904V of power, which is quite astonishing. Who knows if it is completely Prime stable, or whether it can sustain even booting up a game, but it is quite the feat indeed. The achievement was completed using ASRock's Z87 Extreme4 motherboard.

 

We should see more of this crazy overclocking in the near future, and you can be sure we'll be all over the Haswell content when it launches in a few weeks time.

Core i7 3770K overclocked to an insane 7.2GHz using a GIGABYTE Z77X-UP7 motherboard

If you thought your mild overclock was good, or the previous overclocking world record, prepare yourself. Mad222 and John222 from HKEPC have found the golden Core i7 3770K, which has been used to reach a new world record overclock.

 

TweakTown image news/3/0/30260_01_core_i7_3770k_overclocked_to_an_insane_7_2ghz_using_a_gigabyte_z77x_up7_motherboard.jpg

 

The two overclockers used their Core i7 3770K with 1.908 volts pulsating through it to reach a maximum clock speed of 7,208.19MHz - or 7.2GHz! This was achieved using a BCLK of 114.42 on a GIGABYTE Z77X-UP7 motherboard. This overclock is even more special, considering the two overclockers kept Hyper-Threading enabled, which means we have the four physical cores and four logical cores all cranking at 7.2GHz.

Intel debuts Silvermont microarchitecture, features higher performance, lower power draw

Intel has announced the new Silvermont microarchitecture that, as you would expect, brings with it increased performance and decreased power draw. The new architecture will rely on Intel's 22nm Tri-Gate SoC process to realize these performance gains and power draw reductions.

 

TweakTown image news/3/0/30189_1_intel_debuts_silvermont_microarchitecture_features_higher_performance_lower_power_draw.jpg

 

Silvermont is aimed at a wide variety of applications that need low-power CPU's. This means we should see Silvermont showing up in smartphones, tablets, and even datacenters once it is released. Silvermont offers up to three times the performance of current generation Atom processors while consuming five times less power.

CPU-Z result shows Haswell Core i7-4770K at 7 GHz

It looks as though Intel may have a winner on its hands with Haswell when it comes to overclocking. One of the results in the CPU-Z database shows a Haswell CPU running at an impressive 7,012.65MHz. It's important to note that CPU-Z reported that the core was running four cores and four threads, suggesting that higher clocks could be achieved with a single core enabled.

 

TweakTown image news/3/0/30137_1_cpu_z_result_shows_haswell_core_i7_4770k_at_7_ghz.jpg

 

Also interesting to note is the fact the BCLK was reported as 91.07MHz, suggesting that Haswell might scale better with a lower BCLK and higher multiplier. After all, Intel did increase the maximum multiplier to 77, which was used in achieving this impressive score.

 

As an overclocker, I can't wait to see what I can achieve with Haswell.
