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.

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.

Haswell IMC could make memory overclocking fun again for Intel CPU users in the months ahead

With the introduction of Ivy Bridge, memory overclockers were disappointed to learn that high CPU overclocks were usually only capable with a single stick of RAM, and not with fully populated DIMM slots.

This morning Ocaholic has posted a CPU-Z report that shows an Intel Core i5 4670T overclocked to 3.322GHz using 16GB of Apacer RAM. While a RAM overclock of 1.661GHz (3.3GHz DDR) is nothing special with a single RAM stick, the important thing to note is that it was achieved with all four DIMM's populated.

 

This means that the IMC used in Haswell could resurrect the good old days of speedy memory overclocking on Intel platforms in the months ahead.

Intel lifts their game with their integrated graphics on Haswell

Intel have just taken the wraps off of the new naming on their integrated graphics found in the fourth-generation Core processors, otherwise known as "Haswell". Welcome to the Intel Iris and Iris Pro Graphics. Iris Pro will be available on select CPUs denoted by an R at the end, such as the i7-4770R.

 

Iris is a huge leap over the previous third-generation Core processors, with nearly twice the graphics performance and over three times the graphics performance of the second-generation Core processors.

 

TweakTown image news/3/0/30100_01_intel_lifts_their_game_with_their_integrated_graphics_on_haswell.png

 

When Intel compare their fourth-generation Ultrabook part, the Core i7-4558U (a 28W part) gets pitted against the Core i7-4650U (a 15W part) and the third-generation Core i7-3687U (a 17W part) it is a decent distance from them in terms of performance. Compared to the previous-generation part, the new i7-4558U is over twice as fast in 3DMark 11, and around 1.5x the performance in both 3DMark 06 and 3DMark Vantage.

Moving into higher-end of things, we have the fourth-generation Core i7 4900MQ (47W), Core i7-4950HQ (also a 47W part) and the Core i7-4950HQ (a 55W part) compared against the third-generation Core i7-3840QM (a 45M part). As you can see, the new processors' integrated graphics have some great performance gains.

AMD introduces heterogeneous Uniform Memory Access

This morning AMD announced the next big advancement concerning their APU technology. AMD heterogeneous Uniform Memory Access (hUMA) is an intelligent computing architecture that enables the CPU, GPU, and other processors to work in harmony from a single piece of silicon in a single pool of memory and seamlessly move task to the best suited processing unit.

 

TweakTown image news/3/0/30038_1_amd_introduces_heterogeneous_uniform_memory_access.png

 

This means that in a single application, some calculations will run on the CPU while others run on the GPU accessing the same memory though the same addresses without worrying about which software touched the data last. AMD has been able to achieve this by moving the GPU and CPU onto a single die and then AMD enabled the GPU to have direct access to the CPU memory from the same address space. Finally AMD was able to simplify the data sharing by updating the GPU memory set so that it can follow pointers and complex data structures in the same way that the CPU does. These advancements allowed for better efficiency and lower power consumption.

AMD is touting hUMA as restoring the GPU to the world of Uniform Memory Access. As it sits now the GPU utilizes non-uniform memory access and creates a mass of coding headaches for developers. With hUMA application coding can be simplified, and made more efficient throughout the code base.

Is this Haswell's box art? It's definitely not out of the question

VR-Zone has posted up a picture of what appears to be box art for the upcoming Intel line of processors known as Haswell. Intel is really pushing a conceptual computing and creativity aspect this year, so the box design definitely fits within that strategy. But, is it the actual box art?

 

TweakTown image news/2/9/29989_1_is_this_haswell_s_box_art_it_s_definitely_not_out_of_the_question.jpg

 

The box art shown above departs from the typical box art used by Intel. For instance, the top part of the front of the box features a wider case-badge instead of the typical small badge. We likely won't know for sure until Haswell launches at Computex in early June, which we reported earlier today.

Qualcomm will begin mass producing its next flagship Snapdragon 800 SoC in May

After a very successful first quarter for the Snapdragon 600, Qualcomm is moving forward with production on its next-generation system on a chip processor for mobile devices. A Qualcomm exec has confirmed with Engadget that the Snapdragon 800 is expected to move into mass production beginning late May.

 

TweakTown image news/2/9/29980_1_qualcomm_will_begin_mass_producing_its_next_flagship_snapdragon_800_soc_in_may.jpg

 

Based around the Krait 400 architecture, the Snapdragon 800 is a quad-core beast that could likely see clock speeds as high as 2.3GHz with very low power consumption. An internal Adreno 330 GPU will be capable of 4K playback at 30fps. 802.11 B/G/N Wi-Fi, USB 3.0 and 4G LTE are also built into the chip, alongside a quick charging circuit and voice command capabilities.

 

Qualcomm is keeping quiet on which handset manufacturers have placed orders and as such, there is no official word, or speculation on which upcoming smartphones will feature the new SoC. We will tune an ear to the market as always and report back once we get word on any upcoming devices featuring the Snapdragon 800.

Intel to introduce 4th gen Intel Core processor (aka Haswell) at Computex in Taipei on June 4th

This morning Intel announced via its Facebook page and Twitter account that it would be unveiling its next-generation Core processor family at Computex on June 4th. Codenamed Haswell, the new processor family is no secret at this point, though.

 

TweakTown image news/2/9/29979_1_intel_to_introduce_the_4th_gen_intel_core_processor_aka_haswell_at_computex_in_taipei_on_june_4th.jpg

 

Haswell architecture is designed to optimize the power savings and performance benefits from the move to FinFET transistors on the improved 22nm process, and feature a fully integrated voltage regulator, moving the power scaling duties from the motherboard and onto the processor itself.

 

The new king of speed is said to be the Core i7-4770K, which is a quad-core, eight thread 3.9GHz beast. While the middle of the road low power consumption chip is said to be the Core i5-4670T that runs four cores at 3.8GHz.

 

Our own Anthony Garreffa posted a complete lineup of the upcoming Haswell processors back in December.

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.

 

TweakTown image news/2/9/29701_06_rumortt_amd_working_on_a_5ghz_chip_based_on_their_vishera_architecture.jpg

 

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!
