Intel Ivy Bridge-E benchmarked, tests show it's 5-10% faster than Sandy Bridge-E

Toppc, a member of Chinese overclocking forum Coolaler.com, has managed to get his hands on a pre-release Ivy Bridge-E CPU. This new CPU is the successor to the Sandy Bridge-E line of CPUs on Intel's LGA 2011 platform. It's widely expected to feature up to 12 cores and 30MB of L3 cache.

The results from the comprehensive benchmark suite show that the Ivy Bridge-E CPU is somewhere between 5 and 10 percent faster than the current generation Sandy Bridge-E processors. The benchmark suite included SuperPi mod 1.6, CPU Mark '99, WPrime 1.63, Cinebench 11.5, 3DMark Vantage (CPU score), and 3DMark 06 (CPU score).

 

The new line of Ivy Bridge-E CPUs are expected to launch towards the end of the second half of this year. They should be mostly drop-in compatible with current LGA 2011 systems, though you'll likely need a BIOS upgrade from your manufacturer.

RumorTT: AMD working on a 5GHz CPU based on their Vishera architecture

AMD are definitely doing their best to jump back into the market, as they're really struggling right now. They've won contracts to have various products in all three next-gen consoles, and their Never Settle promotion for Radeon GPUs is doing very well.

In the CPU market however, things aren't so well, as Intel are just dominating too much. Haswell is about to launch, Intel's fourth-generation Core processor, and AMD have, well, nothing - or do they? There are now rumors going around that AMD are to release a super-FX CPU based on the Vishera architecture that makes the FX-8350 come to life, which runs at 4.2GHz.

 

This new CPU, codenamed 'Centurion', will be released in very limited quantities and would ramp the clock speed up to 5GHz - all on air. There's no details on what voltage or supporting hardware needed to run at this speed - but if the rumors are true, we're looking at around $795 for this limited edition FX CPU.

 

I think this CPU would have to run rings around Intel's Haswell CPU - especially at $795, which would most likely buy you a Core i7 4770K, a good motherboard and 16GB of RAM in just a few months time.

Intel details Haswell overclocking at IDF Beijing, not too much different from Ivy Bridge

Intel has detailed overclocking the new Haswell architecture at IDF Beijing and not much has changed from overclocking Ivy Bridge. One major difference between Ivy Bridge and the upcoming Haswell architecture is that Haswell features just one voltage input that can be as high as 3.04v. Ivy Bridge had numerous different voltage inputs that were controlled externally.

 

TweakTown image news/2/9/29665_1_intel_details_haswell_overclocking_at_idf_beijing_not_too_much_different_from_ivy_bridge.jpg

 

The one new rule of thumb for overclocking Haswell is that the input voltage (VCCIN) needs to be at least 400mV higher than the core voltage (VCORE). This yields VCCIN >= VCORE + 400mV.

 

Other changes include an increased max multiplier--80x vs 63x--though this doesn't mean Haswell will be able to achieve 8Ghz. Intel has also included BCLK ratios that are present on the X79 platform.

 

There are plenty of other nuances for overclocking the new Haswell CPUs and HWBot has done a great job of detailing all the ins and outs, so head over to source #1 below to check it out!

Intel's 2013 update to their Xeon family isn't being rushed, but it will pack quite a punch when it arrives

With no real competition in the server/workstation space, Intel aren't just rushing out their 2013 update to their Xeon platform of processors. Toward the end of this year, we should expect the Ivy Bridge-based Xeon E5 and E7 processors, while the Xeon Phi MIC/co-processor/accelerator gets segmented into more SKUs and thanks to a new stepping, we're seeing clock speeds pushed from 1.1GHz to 1.238GHz with nearly the same TDP and form factor.

What we will see when the new Xeon processors arrive, is a 12-core part with 30MB of cache and quad-channel DDR3-1866 server memory paths per socket with clock speeds pushing 3GHz and Turbo Boost to boot. Power consumption on these insane 12-core processors should see a helping hand from its 22nm FinFet '3D transistor' process.

 

Toward the end of the year, we should expect the E5-4600 v2 series, which is the same as the above solution, but 4-socket-enabled where the dual QPI links make a square interconnection layout between the CPU. At around the same time, we should see the 15-core IVB-EX enterprise Xeon processors - the E7-4800 v2 and 8800 v2 - which will replace the Westmere-EX processors we have had for the past couple of years now.

Intel's Haswell CPU begins shipping to PC makers

The time is nearly upon us, when we get to see what the fourth-generation Core processor from Intel can do. Haswell, as it's otherwise known, has begun "shipping to customers now and will launch later this quarter" according to a source of CNET's.

Intel is expected to make a statement at the IDF Beijing conference next week, and should arrive in June for Computex in Taipei. Haswell is a special chip, as it is a next-generation processor that will scale incredibly well, from Ultrabooks to smart devices, right up to the high-end desktop and more. Intel CEO, Paul Otellini, has said that Haswell's new micro architecture will deliver "the single largest generation-to-generation battery life improvement in Intel history."

 

The chipmaker has confirmed the USB bug attached to chipsets, known as errata, will be "in production" during the initial ramp which happens later this month:

 

4th gen Core is on track for a mid-year launch. Intel issued a PCN documenting a chipset USB errata and stating that chipsets with the errata will be in production during the initial ramp. But Intel has confirmed that there is no chance of data loss or corruption. This issue has only been observed with a small subset of USB SuperSpeed thumb drives and does not affect other USB peripherals. We take all customer issues seriously and should any customer have a question or concern they can always contact Intel customer support.

AMD hints at an early Steamroller arrival, could be here a year early

In a recently released presentation, AMD has hinted that its new Steamroller micro-architecture is on track to be released this year. This comes at a surprise as most industry insiders thought that the new architecture would not arrive until mid to late next year.

X-Bit Labs is reporting that AMD has pushed forward its plans for Steamroller and the new chips will be compatible with current sockets and that the new server microprocessors will support PCI-E 3.0. Desktop chip's featuring Steamroller technology will most likely not be seen until next year though.

Intel Haswell demo at GDC 2013 has GRID 2 playing without a hitch

GDC 2013 - Intel have shown off GRID 2 on their upcoming Haswell-based processor, running purely from the integrated graphics. It looks like it is a decent res - maybe 1920x1080 - and it looks like it's pumping out around 30fps.

 

 

We don't have any of those details on hand, but you can tell from the video it looks sharp and is running smooth. Playing games at 1080p at 30fps on integrated graphics is a nice achievement, something that will mix well with upcoming Haswell-based Ultrabooks.

AMD unveils Richland 35W mobile APUs, provides better power management - up to 38% less consumption

AMD has released its Richland line of 35W mobile APUs this morning. The company says that it has been shipping the processors to PC makers since January and that devices running the new APU's are available now.

Richland is may be the new APU in town, but not much of it is different than its predecessor Trinity. The same Piledriver based CPU cores are still there as well as the Radeon HD 6900 based GPU. The new APU is even fabricated on the same 32nm process. The difference lies within more efficient transistors, which provide better power management and better utilizes the existing architecture.

 

Like Trinity, Richland manages power states via a 32-bit microcontroller. Both have a network of thermal sensors built-in that report back to the MCU, whereas most of these go unused in Trinity, Richland takes full advantage of the sensor network. This allows the CPU and GPU clocks to be changed based on the APU's temperature.

 

Richland utilizes better algorithms to more precisely tune those clocks based on temperature as well. AMD claims that these improvements allow Richland to consume 17% less power than Trinity and 38% less when playing 720p video.

Haswell's USB3.0 bug will require a chipset revision to fix

Intel has a bit of a problem on its hands. It's probably not as terrible as the Sandy Bridge SATA controller issue, but it could end up being another costly fix for the chip giant. According to Fudzilla, the problem cannot be fixed by a mere software update. Rather, the chipset will require a new revision to take care of the issue.

 

TweakTown image news/2/9/29027_1_haswell_s_usb3_0_bug_will_require_a_chipset_revision_to_fix.jpg

 

The bug isn't too major. If a USB 3.0 port is being used when the system is put to sleep (S3 state), the device will need to be reconnected upon waking the machine. It's nothing more than a slight hassle, but this is the second chipset glitch experienced by Intel in less than a year.

 

Motherboard vendors are saying that June is still the planned introduction for Haswell, so it looks like the first batch of motherboards could possibly be coming with the buggy chipset. We'll know more as the proposed launch period nears.

Intel's Haswell chips reportedly having issues with USB 3.0

There's some bad news coming out of the cracks of the Internet today, with Hardware.info reporting that they have talked with a "reliable source" who says that the next-generation processor from Intel named Haswell, is having issues with USB 3.0.

 

TweakTown image news/2/8/28890_04_intel_s_haswell_chips_reportedly_having_issues_with_usb_3_0.jpg

 

The site claims they've taken a look at a document that Intel reportedly sent out to inform system builders of a bug surrounding USB 3.0 and Haswell - the bug specifically has issues with waking from sleep and using a USB 3.0 device. If the system exits S3 level sleep while a user is accessing data on a USB 3.0 drive, their session with that data will end.

 

This would mean if you're working on a document open before you put your PC to sleep, or it went to sleep after a period of time, when you come back that document could be just blank. Intel is reportedly aware of this issue and are said to be trying to make partners accept the flaw before purchasing the affected CPUs.
