According to a translated report from Taiwanese publication Economic Daily (via Macotakara), Apple is apparently in the process of preparing suppliers for the launch of a Retina MacBook Air in Q3 2013. The report appears to claim that both 11- and 13-inch variants of the MacBook Air will launch with Retina displays in addition to an upgrade from Intel’s new Haswell platform. Apple supplier Quanta is expected to begin receiving shipments of the new components in the second quarter, according to Economic Daily.
Today’s report of course goes against recent claims from analysts predicting the next-gen MacBook Air would land in Q2 or Q3 without a Retina display. We heard last year that Apple was working on MacBook Airs with Retina displays, but sources indicated the power drawn from the Retina Displays combined with the thin and light form factor of the MacBook Air may pose challenges for Apple and its product manufacturers.

On Monday, we told you that T-Mobile was enhancing its 4G network in Atlanta, Seattle, and Minneapolis to provide access to its iPhone-compatible 1900 MHz spectrum for more users. Chief Technology Officer for T-Mobile USA Neville Ray announced more enhancements to the network today, including the roll out of more iPhone-compatible 4G HSPA+ to five major metro areas, such as: Chicago; Reno, Nev.; and Fresno, Sacramento and Southern Calif.
A spokesperson confirmed to us that the launch of the enhanced network in these new areas brings T-Mobile’s total covered for iPhone compatible 1900 MHz PCS spectrum to 100 million people.
Internal tests of unlocked iPhone 4S devices running over 4G (HSPA+) on our 1900 MHz network recorded on average 70% faster download speeds than iPhone 4S devices on AT&T’s network. Savings based on comparison of T-Mobile $69.99/month Unlimited Talk, Text and Data plan against AT&T Unlimited Talk, Text, and 3GB Smartphone Data plan.
T-Mobile also said more enhancements to the network are on the way to “Boston, Chicago, Los Angeles, the New York metro area, Philadelphia, and San Diego,” with many customers already experiencing unlocked iPhone “speed sightings.”
A full list of areas included in the rollout is below:
Slashgearran the browser on the dual-core 800MHz A5 iPhone 4S against the latest and greatest Galaxy S II with dual-core 1.5GHz Qualcomm processor (skip ahead 4:30). From the video it looks like the iPhone 4S was faster (as expected). However, in their words…
…from initial results the iPhone 4S performs quite well, I’m sure everyone expected that as the original held its own pretty well too. One of the fastest processors around currently, the 1.5 GHz Qualcomm in the Galaxy S II performs very well but is just barely by a hair beat by the new A5 dual-core iPhone 4S in most tests. We could argue about this all day, or try other sites but when it really comes down to it iOS is highly efficient — not to mention many many websites are designed with iOS in mind.
Anandtech has published some interesting findings based on their extensive Samsung Galaxy S II review. It’s the first smartphone to use the graphics processing unit based on the Mali-400 core from ARM Holdings, a fables chip maker from the UK. In fact, Samsung has engineered and manufactured its own system-on-a-chip solution for the handset.
They call it the Exynos 4210 and it combines a dual-core Cortex-A9 CPU core and the aforementioned Mali-400 GPU sporting four cores. The resulting performance, says Anandtech, is comparable to Texas Instruments OMAP 4 chip that incorporates Imagination Technologies’ PowerVR SGX540 GPU core. However, the quad-core 1.2GHz Exynos 4210 probably won’t hold a candle to iPhone 4S, which will likely carry the same dual-core processor-GPU combo as the iPad 2′s 1GHz A5 chip:
Samsung implemented a 4-core version of the Mali-400 in the 4210 and its resulting performance is staggering as you can see above. Although it’s still not as fast as the PowerVR SGX 543MP2 found in the iPad 2, it’s anywhere from 1.7 – 4x faster than anything that’s shipping in a smartphone today.
Interestingly, and per the GL Benchmark included below, the Exynos 4210 is more than twice as fast compared to the Galaxy Tab 10.1 that runs Nvidia’s Tegra 2 chip and nearly four times speedier than iPhone 4′s 800 MHz A4 chip that sports the PowerVT SGX535 GPU core. However, the 4210 falls short in the triangle throughput department, a big disadvantage over the iPad 2′s A5 processor that clocks nine times the graphics performance of the original iPad’s A4 chip.
Triangle throughput is important in graphics-intensive games and will become key in “future games that may scale along that vector rather than simply increasing pixel shader complexity”. The video of Anandtech’s Samsung Galaxy S II review is right after the break.
