Intel's new CPUs flawed: full system control over USB

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jan 11, 2017 12:49 pm

It looks like Intel could be in for a world of hurt, and a massive explanation for the reason behind some of its new processors being stupidly easy to hack into a PC - through a simple USB port.

 

intels-new-cpus-flawed-full-system-control-over-usb_13

 

Positive Technologies, a security vendor, has discovered that some of Intel's new CPUs have a debugging interface that can be accessed through USB 3.0 ports. This provides the hacker - and at the point of using as USB flash drive, any person in the world that can hold a USB stick in their hands - full control over the PC. Worse yet, it is completely undetectable by current security tools.

 

The possibilities of this are virtually unlimited, as someone could plug a USB 3.0 stick in and upload malicious code, keyloggers, and virtually anything else they want. The same flaw allows someone to make the PC completely inoperable, where it is capable of rewriting the entire BIOS. Yeah, that's a pretty big deal.

Intel's 10nm Cannon Lake CPUs coming in 2017

By: Derek Strickland | More News: CPU, APU & Chipsets | Posted: Jan 9, 2017 3:33 pm

CES 2017 - Although Qualcomm has just created the world's first 10nm chip with its Snapdragon 835 SoC, and TSMC is working on 7nm chips, Intel affirms that its own 10nm processor will still release in 2017 despite original delays.

Intel's eight-generation 10nm Cannon Lake CPUs were originally supposed to release in 2016, but the chips were delayed when Intel had some troubles shrinking down the chip's transistors. Now we're right at the beginning of 2017 and Intel has only just launched its seventh-generation Kaby Lake CPUs on the new 200-series Z270 chipset, leading many to believe Cannon Lake would be pushed into 2018--but Intel has set the record straight.

 

At CES 2017 Intel CEO Brian Krzanich demoed a prototype 2-in-1 device running an eight-gen 10nm Cannon Lake CPU that displayed a promo video. "For those who are wondering if Moore's Law is alive, if 10 nanometers going to be here, the answer is absolutely yes," Krzanich said on stage.

Core i7-7700K hits 7GHz with all cores enabled this time

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Jan 9, 2017 2:08 am

CES 2017 - When we first reported about Intel's new Kaby Lake-based Core i7-7700K hitting 7GHz, it was only with 2 cores enabled - so impressive to see 7GHz, but not so impressive without all 8 cores enabled.

 

core-i7-7700k-hits-7ghz-cores-enabled-time_03

 

During CES 2017 - overclockers were able to hit 7GHz on the 7700K with all of the CPU cores enabled - using LN2 of course. They hit 7026MHz specifically, with a CPU multiplier of 70, and an FSB of 100.

 

The new Core i7-7700K has a base clock of 4.2GHz and boost of 4.5GHz, with most people able to hit 5GHz without a problem. The CPU retails for $305 in the US, and obviously changes throughout the world - so for me in Australia, it'll cost $1500 or something ridiculous (jokes, jokes - probably $1200).

Qualcomm announces Snapdragon 835 - the first 10nm SoC

By: Lana Jelic | More News: CPU, APU & Chipsets | Posted: Jan 3, 2017 10:00 pm

CES 2017 - Qualcomm has officially introduced their Snapdragon 835 processor with X16 LTE. Back in November, we reported that the Snapdragon 835 is the first 10nm SoC and we also put an end to the speculations that Qualcomm's next chip will be named Snapdragon 830.

 

qualcomm_01

 

As of today, the Snapdragon 835 is officially out and we, as the phone manufacturers, have high expectations from the Qualcomm's latest processor. The Snapdragon 835 features a new Kryo 820 CPU with four high-performance cores running at 2.45GHz and four efficiency low-power cores running at 1.9GHz. These are backed by dual channel LPDDR4x memory at 1866MHz.

 

The Snapdragon 835 also has a new Adreno 540 GPU with support for DX12, Vulkan, OpenCL 2.0 and OpenGL ES 3.2. Qualcomm also upgraded the DSP inside of the Snapdragon 835 by including the Hexagon 682, a machine learning-focused upgrade to the Hexagon 680 in the Snapdragon 820.

AMD's new Ryzen CPU could hit 5GHz, even when air-cooled

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Dec 30, 2016 11:26 pm

AMD's upcoming Ryzen CPU could be a great overclocker, something we were teased at during AMD's recent Tech Summit event in Sonoma, California - but now we're hearing that Ryzen might easily hit 5GHz... on air cooling.

 

amds-new-ryzen-cpu-hit-5ghz-even-air-cooled_10

 

The news is coming in a very cryptic way, with Hexus reporting that "the most stirring extra piece of information is mysteriously hidden inside a binary string printed nonchalantly above a feature image on page 10 of the magazine's printed article"... something you can see above.

 

Reddit user lolwut996633 noticed it, and when put into a binary to plain text converter, it reads:

 

ZenOC@Air=5G

 

This would lead us to believe that the Canard PC article was teasing Ryzen is capable of 5GHz on air, which is damn impressive - because what will we expect for water cooling, and gasp - LN2?!

7700K overclocked to 7GHz, just 2 cores enabled on LN2

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Dec 29, 2016 8:21 am

Intel are just days away from making their new Core i7-7700K processor and entire Kaby Lake family of CPUs official, but before that we're seeing the 7700K hit 7GHz.

 

7700k-overclocked-7ghz-cores-enabled-ln2_01

 

Before you pull out the celebration play list on Spotify, the 7700K was cooled by LN2, and the chip was reduced to just 2 cores. Oh, and it was thirsty for power requiring 2V of power.

 

Intel and AMD have a massive CES ahead of them next week, but a 7700K at 7GHz does sound delicious. Now give me that with all cores enabled, less power consumption, and an AIO cooler that keeps it cool enough and I'm happy.

Intel's Core family retired in 2019, next-gen x86 coming

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Dec 27, 2016 12:09 am

The holidays can be an interesting time, with Intel rumored to be retiring its Core family of processors in 2019 with the release of Tiger Lake, which will be succeeded with a more efficient, faster approach to the x86 architecture.

 

intels-core-family-retired-2019-next-gen-x86-coming_01

 

Bitsandchips.it is reporting that Intel's next CPU family will be similar to what AMD has done with its Zen architecture, blending in power consumption/performance /price - and in order to save physical space (smaller die), and improve the power consumption/performance ratio, Intel will reportedly get rid of old SIMD and legacy hardware.

 

This means that we might not have 100% backwards compatibility, but these CPUs won't be here until 2020 - a long time from now. Intel will be able to make a lean, efficient x86 architecture that will compete with AMD's nearly-here Zen architecture. What I'm taking away from this is that AMD will be ahead of the game for a few years until Intel can get their act together with a new architecture to begin competing against the star-studded launch of Zen.

AMD Ryzen leaked review, beats 6900K which costs $1000

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Dec 25, 2016 2:53 pm

Things are really heating up for Intel just weeks away from the official launch of its next-gen CPU architecture, Kaby Lake - with a leaked review of AMD's new Ryzen processor.

 

amd-ryzen-leaked-review-beats-6900k-costs-1000_08

 

The review had the new Ryzen CPU had its clocks limited to 3.15GHz base and 3.3GHz boost, but AMD has confirmed the enthusiast SKU of Ryzen will kick things off at 3.4GHz, with lots of headroom for overclocking. CPCHardware is a PC magazine in France that has been in operation since 2001, and is reportedly an engineering sample set out to the press under NDA.

 

amd-ryzen-leaked-review-beats-6900k-costs-1000_06

 

There are some interesting benchmark results, with a bunch of render programs being run on the Ryzen CPU at 3.3GHz, against the $1000 processor from Intel in the form of the Core i7-6900K. Not only that, but we have the 6800K, FX-8370, and more.

AMD's next-gen Ryzen benched against 7700K and 6900K

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Dec 19, 2016 11:27 pm

AMD teased their next-generation CPU architecture not too long ago at their annual AMD Tech Summit 2016 event in Sonoma, California - benchmarking the new 8-core/16-thread version of the Summit Ridge platform, better known as Ryzen.

Now we have some new benchmarks that have been leaked, with Cinebench R15 results that pit Ryzen against Intel's new Kaby Lake-based Core i7-7700K processor.

 

amds-next-gen-ryzen-benched-against-7700k-6900k_01

 

AMD's new Ryzen CPU clocked at 3.4GHz (it will be faster than this when it launches) against the Core i7-7700K, with Ryzen coming out on top - but a fair margin, too. This is to be expected however, as the 7700K is a 4-core/8-thread CPU against the 8-core/16-thread Ryzen CPU.

 

Cinebench R15 results:

 

  • AMD Ryzen - 1188
  • Core i7-7700K - 966
  • Core i7-7700K @ 5GHz - 1083
  • Core i7-6900K - 1500
  • Core i7-6950X - 1800

7700K delidded, 30C reduction in temps - WTF, Intel

By: Anthony Garreffa | More News: CPU, APU & Chipsets | Posted: Dec 16, 2016 2:11 am

If you've been keeping up with Intel's upcoming Kaby Lake-based Core i7-7700K, you'll know that they run - well, rather freakin' hot. Way hotter than the previous 6700K, and normally double the temps of the 6700K on the current 7700K engineering samples that are being sent around to various tech press.

 

7700k-delidded-30c-reduction-temps-stuffed-up-tim_02

 

New work has been done on the 7700K with retail samples, and cooled by the Thermalright 6 cooler by AnandTech forum member 'RichUK'. Out of the box, the temperatures of the Core i7-7700K hit 60C under load, but when the 7700K was pushed to 5GHz and pushed to 100% load, the temperatures spiked at a mammoth 96C.

 

7700k-delidded-30c-reduction-temps-stuffed-up-tim_03

 

Even at 96C, the 7700K was stable at 5GHz with 1.34V coursing through its silicon, while 1.264V was used at a stable 4.7GHz (and hitting 83C) on a Corsair H110i cooler on quiet mode.
