New Retina MacBook Pros can drive 4K displays at 60Hz – when running Windows, Mac OS needs new drivers

4kok

Tests by French site Mac4Ever.com found that current model Retina MacBook Pro machines can use their Thunderbolt 2 connections to drive the Sharp PN-K321 4K display at 60Hz when running Windows 8.1 with the latest NVidia drivers, rather than the 30Hz possible with OS X. This suggests that OS X will be able to do the same when Apple updates the rMBP video/Thunderbolt 2 drivers.

While 30Hz is good enough for movies, our own Seth Weintraub found on his bargain Seiki that it gives a poor experience when scrolling webpages, and is of course completely unusable for games. 60Hz, in contrast, gives a smooth experience when using a computer. The mystery had been why the latest Retina MacBook Pros, with Thunderbolt 2 support, were limited to 30Hz when the specs should have made them capable of double this – and the video drivers appear to be the answer …

NVIDIA introduces GeForce 700M Series GPU, prime fits for the next high end iMacs/MacBooks

NVIDIA-GeForce-graphics-GPU-700M

NVIDIA announced a new series of notebook GPU’s today branded as the 700M series. Introduced today are five new graphics cards in total, and NVIDIA said they would be available in a long list of laptops over the next few months. The five new graphics cards include two options aimed at the “mainstream segment”, the 720M and the 735M, while the remaining three, the 740M, 745M, and 750M, will be “for the performance segment” of the market.

700m-lineupThe graphics cards are being touted by NVIDIA to “maximize performance and experience,” but they also more power efficient than their predecessors. Because the 700M Series is notebook-only, expect these to be less powerful than a desktop version of the 700 Series that may be announced sometime in the future.

Helping our new 700M chips reach such lofty levels of performance is GPU Boost 2.0, a GPU innovation that extracts every ounce of available computing power from the graphics processor. Before GPU Boost, GPUs were held back by synthetic benchmarks that pushed chips and power usage to the limit, far beyond the levels typically seen when playing games. This ‘worst case scenario’ forced us to throttle GPUs, leaving spare performance on the table when playing games.GPU Boost resolves this problem by monitoring power usage and temperatures, enabling the GPU to use every last ounce of performance without exceeding safety or comfort limits.

While the press release from NVIDIA said the new GPUs will be available in nearly every notebook maker other than Apple, it is possible these GPUs will be seen in the next-gen MacBook Pro with Retina Display. The current 15-inch MacBook Pro with Retina Display sports a NVIDIA 650M GPU, as does the high-end 21-inch iMac model, so an upgrade to the 700M series only makes sense.

New NVIDIA GeForce 700M GPUs Squeeze Every Drop Of Performance Out Of Notebooks, Automatically

Monday, April 1, 2013

NVIDIA today announced five new notebook GPUs which deliver a trifecta of technologies that seamlessly and automatically maximize a consumer’s notebook performance and experience.

With no effort or input from the notebook user, the technologies work in the background to save battery life, enhance performance and enrich the visual experience — providing the best notebook experience the GPU can deliver. They include:

New NVIDIA GPU Boost™ 2.0 technology, which intelligently adjusts GPU clock speed to maximize graphics performance.

NVIDIA® Optimus™ technology, which enables extra-long battery life by switching the GPU on and off so it runs only when needed.

GeForce® Experience™ software, which adjusts in-game settings for the best performance and visual quality specific to a user’s notebook and keeps GeForce drivers up to date.

“There is an elegant simplicity to NVIDIA’s GeForce 700M notebook technologies,” said Rene Haas, vice president and general manager of the notebook business unit at NVIDIA. “You use your notebook how you want, and GeForce makes your experience awesome.”

Incorporating all three of these technologies, the new lineup of NVIDIA GeForce 700M GPUs includes GeForce GT 750M, GeForce GT 745M, and GeForce GT 740M GPUs for the performance segment, as a well as GeForce GT 735M and GeForce GT 720M GPUs for the mainstream segment.

NVIDIA GeForce 700M GPUs are available today. Every leading notebook manufacturer will be introducing notebooks with GPU Boost 2.0 technology, including Acer, Asus, Dell, HP, Lenovo, MSI, Samsung, Sony and Toshiba.

More information about the GeForce 700M family of notebook GPUs is available at http://www.GeForce.com.

NVIDIA graphics chip promises four times the speed, but not until 2016

nvidiaNVIDIA has announced its latest GPU, Volta, that promises 1Tb/s of memory bandwidth—almost four times the speed offered by its current top-of-the-range Titan GPU. However, don’t expect to see the chip appear in a Mac near you until 2016.

Reporting from the GPU Technology Conference in San José, Forbes explained the speed of the chip would enable it to process all the video on a full Blu-ray disc in just 1/50th of a second.

NVIDIA CEO Jen-Hsun Huang told the conference:

Volta is going to solve one of the biggest challenges facing GPUs today, which is access to memory bandwidth. We never seem to have enough! This is unbelievable stuff.

The speed is made possible by stacking DRAM layers on a single chip and drilling holes through the silicon to connect them. This far ahead, the company has sensibly avoided committing itself to either a price or a more specific release date.

Apple announces redesigned 21.5-inch iMac will be available Friday, November 30th; 27-inch models still on for December

After being unveiled in late-October, Apple has officially announced that the 21.5-inch iMac will become available this Friday, Nov. 30. The latest iMac is the eighth generation and “is the most beautiful iMac we have ever made,” according to Apple Senior Vice President of Worldwide Marketing Phil Schiller. It features a 5mm edge, edge-to-edge glass, LED-backlit display with IPS technology, a FaceTime HD camera, dual mics, four USB 3 ports, two Thunderbolt ports, OS X Mountain Lion, Bluetooth 4.0, and more.

The 21.5-inch iMac is available in two versions. The 2.7GHz quad-core Intel Core i5 model (Turbo Boost up to 3.2GHz) is available for $1,299, featuring 8GB of 1600MHz DDR3 memory, 1 TB (5400-rpm) hard drive, and a NVIDIA GeForce GT 640M graphics processor with 512MB of GDDR5 memory. The 2.9GHz quad-core Intel Core i5 model (Turbo Boost up to 3.6GHz) is available for $1,499, featuring similar specs, except a 1TB (5400-rpm) hard drive that can be configured into a Fusion Drive.

Apple also has a 27-inch version iMac on its way. As we reported earlier this month, the 27-inch version is still set to launch sometime in December, according to Apple. CEO Tim Cook has already discussed that the company is expecting shortages of iMacs. Our sources have indicated that the new iMac is in relatively short supply, mainly outside of the United States. Check out Cook’s comments below:

Apple moves supplier relationship status with Samsung from ‘frenemies’ to ‘enemies’

Just before we heard Apple was not using an ARM-designed processor and instead its first custom CPU design for the new iPhone’s A6, we also heard reports that Apple was reducing component orders from Samsung due to the two companies’ ongoing patent disputes. While we knew Samsung was still—at the very least—manufacturing the new chip, a report from KoreaTimes gives more insight into the company’s involvement directly from a Samsung official. According to the report, the A6 is the first of Apple’s iPhone chips where Samsung did not contribute to development of the technology:

According to industry sources, Apple has not collaborated with Samsung in the process to develop its A6 microprocessor used in its latest iPhone 5. Samsung has handled the manufacturing of the processors used in previous iPhones and believed to have contributed in their design to some degree… It now appears that the structure of the deal has been dramatically adjusted…Apple is still relying on the Korean firm to manufacture its chips but has made it clear it will no longer use its rival’s technology.

We heard conflicting reports in September regarding Apple’s decision to reduce component orders from its biggest supplier, Samsung. Reuters claimed the reduction in orders was an attempt to simply “widen its supply chain,” while others reported Apple is actively reducing orders of displays, memory chips, and batteries specifically due to increasing tension between the companies. According to the report’s source, an unnamed senior Samsung official, Samsung is now only manufacturing the A6 chips on a “foundry basis”:

“There are three kinds of chip clients. Some want us to handle everything from chip design, architecture and manufacturing. Some want us to just design and manufacture. Some want us to just make the chips. Apple is now the third type,’’

Related to today’s report: Apple’s recent hiring of Samsung chip designer Jim Mergard. The report claimed the hiring of Mergard, who was working specifically on ARM chip designs at Samsung and prior, increases the “mutual tension”… Read more

Benchmarked: New iPad’s A5X vs iPad 2′s A5 vs Tegra 3

At the launch of Apple’s third-gen iPad, the company’s Marketing Chief Phil Schiller claimed the device’s new A5X processor with quad-core graphics provided up to 4x the graphics performance of NVIDIA’s Tegra 3 chip. Schiller also claimed the new chip provided 2x the graphics performance of the iPad 2′s A5 chip. NVIDIA was skeptical of the benchmark data behind the claims, but early benchmarks seemed to show A5X outperforming a Transformer Prime running Tegra 3 in the majority of tests.

New benchmark data provided by IGNshows the iPad 2′s A5 chip outperforming both the A5X and Tegra 3 with the A5X’s improved graphics going largely toward powering the new iPad’s high-resolution Retina display of 3.1 million pixels. The A5X shows a significant increase in performance over iPad 2 and Tegra 3 devices only when the chip is not forced to power the Retina display in “off-screen” benchmarks.
