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.

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.

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.

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.

 

TweakTown image news/3/0/30114_1_haswell_imc_could_make_memory_overclocking_fun_again_for_intel_users.jpg

 

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.

 

TweakTown image news/3/0/30100_02_intel_lifts_their_game_with_their_integrated_graphics_on_haswell.png

 

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.

 

TweakTown image news/3/0/30038_2_amd_introduces_heterogeneous_uniform_memory_access.png

 

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.
