Photos of Claimed New 15-Inch MacBook Pro Logic Board Show NVIDIA GT 650M, Retained Layout

The images show an NVIDIA GeForce GT 650M graphics chip and 1 GB of GDDR5 graphics memory, which many have expected would make an appearance in the new MacBook Pro. Interestingly, the posters have also compared the leaked photos with the logic board of the current MacBook Pro, finding the layouts to be nearly identical all the way down to the screw holes on the board.

One of the reports also claims that the new 15-inch MacBook Pro will arrive with 2.3 GHz and 2.5 GHz chip options on stock models, with a 2.7 GHz chip available as a high-end custom configuration. The exact chips to be offered are not detailed by the poster, but some attempts at matching up to Intel's Ivy Bridge offerings can be made.

At the 2.3 GHz level, Apple would have its choice of the Core i7-3610QM or Core i7-3615QM. For a 2.5 GHz chip, the only appropriate Ivy Bridge processor currently available is a dual-core Core i5-3210M, which would actually be the low-end chip. And at the high end, Apple would apparently be offering the Core i7-3820QM as had been seen in benchmarks that appeared last month.

Apple has been widely rumored to be introducing a redesign MacBook Pro with a Retina display and a thinner profile. But if the leaked photos are genuine they may indicate that no redesign of the body is forthcoming, as Apple would be expected to make significant changes to the logic board to accommodate rearranged internals in a thinner enclosure.

An alternative explanation relates to claims put forth late last week by KGI Securities analyst Ming-Chi Kuo, who indicated that a thinner, Retina-capable Mac notebook would appear as a third member of the MacBook family with Apple continuing to offer the existing MacBook Pro alongside the new model for the time being. In that case, these leaked photos could represent the updated version of the current MacBook Pro with the new notebook still remaining under wraps.


ΜΑΛΙΣΤΑ!!! Αρα μάλλον δεν θα δούμε νέα μοντέλα αν αληθεύουν αυτά εδώ! Ειδικά κάτι retina display και τούμπανα κάρτες γραφικών... ούτε για δείγμα!

The World’s Fastest Supercomputer Is American Again



A computer built for the National Nuclear Security Administration by IBM has just been crowned the world's fastest supercomputer, according to the Top 500 Supercomputer list—stealing the lead back from Japan's Fujitsu-designed K computer.

The NNSA computer, called Sequoia, is based on IBM's Blue Gene/Q architecture and manages to reach 16.32 sustained petaflops— that's 16.32 quadrillion floating point operations per second. That blows away the K computer, which only—only!— manages 10.51 petaflops. IBM offers an alternative explanation of its performance, explaining that '"three billion people using a pocket calculator would have to perform one million operations per second to reach equivalent SuperMUC performance." Wow.

It's easy to understand when you consider Sequoia's specs: it houses 1.6 million cores with 1.6 petabytes of RAM. Still, it is the size of a room, filling 96 racks, and is ugly as hell—but then, some people prefer brains over beauty.

Intel christens its 'Many Integrated Core' products Xeon Phi, eyes exascale milestone



Been wondering when the next big leap in high performance computing would hit? Well, Intel would like you to believe the time is now and the name of that revolution is the Xeon Phi. Formerly codenamed Knights Corner, the Many Integrated Core product is pushing the field of supercomputers into the era of the exaflop by squeezing a teraflop of performance into a package small enough to plug into a PCIe slot. The Phi brand will, at first at least, be applied to specialized coprocessors designed for highly parallel tasks. The chips are built using Intel's 22nm manufacturing process and 3-D TriGate transistors, piling in more that 50 cores in an effort to combat the inroads made by GPU companies like NVIDIA in the supercomputing space. For more info check out the presentation (PDF) and blog post at the source links.

MacBook Pro Retina: Performance Test

[game over]

Sapphire Debuts the HD 7970 6GB TOXIC Edition as the Fastest GPU in the World



The SAPPHIRE HD 7970 6GB TOXIC Edition is based on the latest HD 7970 GHz Edition GPU from AMD, together with a host of industry first and exclusive features to deliver maximum performance. Its unique 6GB frame buffer is a World first for a consumer graphics card and makes the TOXIC Edition ideally suited to multi-screen gaming as well as providing the extra memory required for demanding professional applications such as content creation, video editing or rendering.

Performance is also World leading. By default, the HD 7970 6GB TOXIC Edition runs at 1050 MHz and with PowerTune Dynamic Boosts rises to 1100 MHz on the engine with the memory clock at 6000 MHz effective. By pressing the new SAPPHIRE exclusive Lethal Boost Button, the beast is unleashed, boosting the core clock speed to 1100 MHz with PowerTune Dynamic Boost to an industry first of 1200 MHz on the engine while the memory is further overclocked to 6400 MHz effective. The fan profile and PowerTune limit is also changed to performance settings. In addition, users will be able to individually tune the card with SAPPHIRE TriXX, the company’s free to download software tool that allows key parameters to be adjusted for maximum performance.

This astonishing performance is achieved partly as a result of a completely new power control system developed by SAPPHIRE – theLethal Power Suite. The Lethal Power suite consists of many premium design features. These include a new 8 phase power design for the GPU VDDC, with an additional one phase each for VDDCI and MVDD. The design uses a brand new double sided Black Diamond Choke for the first time, as well as DirectFET technology and all on a 12 layer PCB to ensure the board runs fast and stable. (The double sided Black Diamond Choke design reduces the temperature around the power design portion by 40 degree Celsius in lab test when compared to the reference PCB design.)

Cooling a card with such extreme performance demands a special solution – and the SAPPHIRE HD 7970 6GB TOXIC Edition has it – with a new implementation of SAPPHIRE’s World acclaimed Vapor-X technology. The Vapor-X cooler on the TOXIC Edition is based on a new vapor chamber designed especially for this model. Heat is carried away by four heatpipes (2 x 8mm plus 2 x 6mm), and finally dispersed by two 90mm fan with aerofoil blades and dust repelling bearings.

The Vapor-X cooler easily handles the heat generated from Toxic HD 7970 even when it is running at over 1200 MHz. Additional peace of mind for the user is provided by another new feature – the PCB Temperature LED: The SAPPHIRE HD 7970 6GB TOXIC Edition has a built in onboard LED for users to monitors the PCB temperature.

Based on AMD’s Graphics Core Next architecture, the SAPPHIRE HD 7970 6GB TOXIC Edition supports all the latest demands of multi-screen applications, multi-threaded Application Acceleration with stream processing, fast HDMI support for high resolution and stereoscopic 3D displays and all the Direct Compute features incorporated in the latest operating systems. But with its exciting feature set the SAPPHIRE HD 7970 6GB TOXIC Edition is able to deliver all this with the highest levels of performance ever achieved from a single GPU.

The SAPPHIRE HD 7970 6GB TOXIC Edition is a limited edition product that will be available to order from SAPPHIRE etailers and retailers from 17th July 2012.
