Intel to block Haswell overclocking on non-Z87 chipsets with new microcode update

Apparently, Intel does not like its customers overclocking their new Haswell chips on non-Z87-equipped motherboards. Several of the large motherboard manufacturers have released workarounds that allow their customers to overclock their Haswell processors on motherboards that did not feature a Z87 chipset.

Unfortunately, those workarounds will only function for just a little bit longer as Intel prepares a microcode update that will firmly lock overclocking abilities to only the Z87 hardware. The update appears to be scheduled for this coming week and it's not clear yet on how the update will be pushed to your system. Intel has also not released word on if the microcode update has already been implemented on new retail processors, but we're sure that they will begin pushing it to them soon.

Intel have been building custom processors for big companies such as eBay and Facebook, are now looking at the datacenter market

Some interesting information is coming out from Intel engineer Ronak Singhal, who has spent most of his 17-year career at Intel developing relationships with the top computer experts in the world.

 

TweakTown image news/3/1/31951_02_intel_have_been_building_custom_processors_for_big_companies_such_as_ebay_and_facebook.jpg

 

The experts he has worked with include huge companies such as Amazon, eBay, Facebook, Google, Microsoft, and more. Singhal spoke with EE Times during a break in a press briefing in regards to Intel's latest Xeon and Atom server chips, where he said: "When three of them all tell you they want the same thing, you know you are on to something."

 

But, as you can imagine, some companies don't want the same thing and want a CPU that is custom-made to their specific needs. In the last couple of years, Intel have been providing some of their biggest customers like eBay and Facebook, with custom versions of their CPUs. Intel is taking this slow, and isn't rushing into custom-made processors for companies just yet, though.

NVIDIA show off Project Logan at SIGGRAPH 2013, providing near GeForce Titan GPU performance on mobile

NVIDIA have had something quite impressive to show off at SIGGRAPH this year, Project Logan. Project Logan is an upcoming Kepler-based mobile SoC, which should really provide mobile devices with a serious punch in performance.

 

 

Kepler is great for NVIDIA, as it scales from the best super computers, right down to mobile devices. NVIDIA have been able to scale the GEFORCE TITAN's 250W performance, down to Project Logan, where it only uses between 2-3W. Of course, we don't have TITAN performance in the size of a mobile, but with the right compromises, we're getting there.

 

 

We have Full HD video support, with NVIDIA saying: "game developers can develop awesome graphics for desktop and more easily bring those capabilities to mobile." NVIDIA used their reference tablet design to show off the power inside Logan, with the demos including full HDR lighting, FXAA, bloom, tone mapping, auto exposure, same environment, moving light, deep tissue scattering. With the videos above for your viewing pleasure.

Intel confirms 4.5 watt Haswell processor aimed towards fanless tablets

Today Intel confirmed the existence of the 4.5 watt Haswell CPU that popped up in a datasheet last month. Intel says that the chip will hit markets before the end of the year and that it will be geared towards fanless tablets and convertibles, which do not have much space for cooling hardware.

 

TweakTown image news/3/1/31911_1_intel_confirms_4_5w_haswell_processor_aimed_towards_fanless_tablets.jpg

 

The 4.5W Haswell is expected to fill in the blank left by Intel's 6W Haswell processors that require an active cooling solution.

 

It should be noted that the 4.5W rating is the SDP or Scenario Design Power, which describes the sustained power consumption for sustained workloads, and that Intel has not released any information on the processors TDP, which is used to describe power draw in short burst.

 

The data sheet in which we first saw the new processor also says that the 4.5W SDP only applies when the clock speed is capped at 800MHz.

Samsung releases more details on their new Exynos 5 Octa processor

A few days ago we reported about Samsung's new Exynos 5 Octa processor, but now we have some more details on the system-on-a-chip (SoC).

 

TweakTown image news/3/1/31870_02_samsung_releases_more_details_on_their_new_exynos_5_octa_processor.jpg

 

The new refreshed 5420 variant of the SoC is based on Mali-T628 MP5 silicon and features four ARM Cortex-A15 cores running at 1.8GHz and four 1.3GHz Cortex-A7s in an ARM big.LITTLE configuration. Samsung are claiming that the refreshed 8-core SoC features 20% more CPU processing power, too.

 

We also have dual-channel LPDDR3 at 933MHz, which will provide the processor with an insane 1.49GBps of bandwidth, which will help out with that Full HD Wi-Fi display support. Image compression technology is involved, which will help save battery power and use efficient multimedia loading, pushing out more hours of use with high resolution displays.

 

We don't know which devices will be powered by these new 8-core, energy-efficient processors, but that information should arrive in the coming weeks.

Expect AMD to release 'Carizo' in 2015, the successor to their Kaveri APU

AMD are continuing on with their APUs, having named a successor to their not-even-released 'Kaveri' APU expected in 2015. Kaveri is their Steamroller-based x86 CPU with a GCN-based GPU and HUMA memory architecture, and won't see the light of day until the second half of 2014.

 

TweakTown image news/3/1/31849_04_expect_amd_to_release_carizo_in_2015_the_successor_to_their_kaveri_apu.jpg

 

But, AMD have named its successor already, which will be known as Carizo. Carizo will arrive in 2015, and will feature even more improvements on the unreleased Kaveri APU. Carizo will probably feature AMD's upcoming Excavator CPU core and hopefully an even better rack of GCN GPU cores. We should expect the memory architecture to receive an injection of speed improvements, too.

Samsung will launch new Exynos Evolved mobile processor next week

Earlier today on Twitter, Samsung announced that next week it will be launching a new Exynos Evolved 5 octa-core processor. The company's current flagship processor, the Exynos 5 Octa, was revealed earlier this year at CES and is just now began being integrated into handsets but as all things go in the electronics world, it appears that a new and improved model has already been developed.

 

TweakTown image news/3/1/31798_1_samsung_will_launch_new_exynos_evolved_mobile_processor_next_week.jpg

 

Samsung says that the new processor will be more powerful and enhanced and while no other information was given, we're kind of hoping to see the Exynos built on a 22nm scale which could bring us closer to seeing 2 GHz to 2.5 GHz clock speeds. The current Exynos is built on a 28nm process and its flagship chip is clocked at 1.8GHz.

ARM will boost mobile processor clock speeds to the 3GHz range by 2014

It was just two years ago that a 1 GHz processor in your smartphone was considered a big deal, but by today's standards 1 GHz is pretty slow. Today, ARM announced that it will be ramping up clock speeds in its mobile processors to the 3 GHz range in 2014.

 

TweakTown image news/3/1/31644_1_arm_will_boost_mobile_processor_clock_speeds_to_the_3ghz_range_by_2014.jpg

 

A statement from the company reveals that it has plans to move away from the 28nm process and begin manufacturing chips on a 20nm process which will set the stage for the 3GHz core speed. TSMC, the fabrication house which has signed a deal to manufacture Apple's new line of chipsets, has said that the new process is expected to deliver a 30 percent increase in clock speed while at the same time a 25 percent reduction in heat. These gains can be attributed to efficiency gains from the next-gen manufacturing process.

 

ARM says that most of the new transistors added will be dedicated to graphics processing performance. The 25 percent reduction in power function will translate into a 25 percent boost in battery life. Since battery life is still the top complaint when it comes to smartphones ARM says that consumers should look forward to the new 20nm process.

RumorTT: Intel's Ivy-E to use solder not paste for die-heat spreader thermal transfer

When it was first announced that Intel was using thermal grease instead of solder to attach the CPU die to the heat spreader on Ivy Bridge chips, the overclocking world became very disappointed. The thermal interface material that was used really left a lot to be desired, and as such, Ivy Bridge chips were not as overclocking-friendly as previous generations.

 

TweakTown image news/3/1/31285_1_rumortt_intel_s_ivy_e_to_use_solder_not_paste_for_die_heat_spreader_thermal_transfer.jpg

 

This morning a forum post by user "Toppc" on the Taiwanese website Coolaler has unveiled what appears to be a next-generation Ivy-E ship, which has been delidded to unveil that Intel has once again switched back to solder as the connecting material between the heat spreader and CPU die.

 

TweakTown image news/3/1/31285_2_rumortt_intel_s_ivy_e_to_use_solder_not_paste_for_die_heat_spreader_thermal_transfer.jpg

 

The chip in question is said to be an Ivy Bridge-E Core i7 4960x, which should retail in the $1000 range on release. Fortunately for us, Toppc cared less about his expensive CPU and more by showing the world what was inside. With Intel switching back to solder, we can most likely expect very respectable overclocking numbers coming from Ivy-E this September.

LeakedTT: Three Intel Ivy Bridge-E SKUs appear in the wild, could arrive as early as September 4th

This morning a slide surfaced that appears to be part of an Intel presentation and details information about the upcoming enthusiast platform from Intel, Ivy Bridge-E. The slide appears to be legit, but faking a PowerPoint slide is not very hard, so keep that in mind while reading.

 

TweakTown image news/3/1/31190_1_leakedtt_three_ivey_bridge_e_skus_appear_in_the_wild_could_arrive_as_early_as_september_4th.png

 

The leak comes from website HardwareLuxx and gives us a new release date as early as September 4th, which is two months earlier than previously speculated. The slide also alludes to a very strict NDA around the new processors. The slide also discloses that the new Ivy-E processors are built on a 22nm process based on Intel's 3D Tri-Gate Transistors.

 

TweakTown image news/3/1/31190_2_leakedtt_three_ivey_bridge_e_skus_appear_in_the_wild_could_arrive_as_early_as_september_4th.jpg

 

Continuing the leak, CPU World has posted information on processor SKUs starting with the i7-4960X, featuring 6 cores (12 threads) at 3.6GHz with turbo up to 4GHz and includes a total of 15MB L3 cache. This is the top-end SKU, which should retail for $999-$1099.
