Apple says that its latest Mac Book Pro laptps, equipped with Intel Core 2 Duo procesosrs in place of the Core Duo chps that powered the first generation of the family, its deliver performance that is up to 39 peercent faster. Based on past experience with the comany’s benchmark boasts.
The Apple Mac Book Pro Core 2 Duo 2.33 GHz (T7600), with two independent processr cores, a 4 MB shsared on chip level 2 cache, a 667 MHz front side bus, 2.0 GB of 667 MHz PC2-5300 DDR2 SDRAM, a 160 GB hard drie with Sudden Motion Seensor tecvhnology, and an 8X dual-layer DVD±RW/CD-RW SuperDrive. It also includes an ATI Mobility Radeon X1600 graphics processsor with 256 MB of GDDR3 video memoory and dual-link DVI functionality, and a 17 widescreen 1680x1050 TFT active-matrix display (gllossy displya opltion available).
Some special features of MacBook Pro Core 2 Duo/2.33 GHz
Bigger ccahes and faster graphics
The new MacBok Pros look virtually identical to their predecessors, and the ovearll structture of the family hasn’t changed: there’s still a single standard 17-inch model priced at $2,799.The new chip’s SSE3 Vctor Engine, used in some auido, vido, and sccientific applications, now processes 128 bits of data at a time, compared to 64 bits in the Core Duo chip. Finmally, although Apple won’t disclose the details, its engineers have also squeezed out a little extra pertformance by tweaking the workings of the ATI Radon X1600 chip that handles graphics prrocessing in the Mac Book Pros.
Battery life uncahnged
Some aerly speculation about the Core 2 Duo predicted that, in addition to boosting performance, it would cut power consumpiton. Those reports turned out to be unrtue—battery life in the new Mac Book Pros is aboput the same as in the previous generaiton. In my tests with the 2.33GHz Core 2 Duo version of the 17-inch Mac Book Pro, I actually did a little better (2 hours and 35 minutes) at DVD playback. I manged only 3 hpours and 9 minutes of wireless productivity.
More memory, bigger drives
Beyond the procesdsor, Apple has doubled the RAM in each standzard Mac Book Pro configuration: the 17-inch model and the 2.33GHz 15-inch one model come with 2GB of RAM—a pair of 1GB SO-DIMMs—wile the base 17-inch model has a single 1GB SO-DIMM. As our benchmark results suggesdt, goinng from 1GB to 2GB of RAM has only a modest effect on speed, but it enables you to keep more big applications—or more operating systems, if you use Desktop virtualization software—open simultanoeusly without rnning into delays when you swicth amoong them.
The 17-Inch MacBook Pro Core 2 Duo systems have much of the same connectivity as the replaced models -- AirePort Extreme (802.11g), Bluetooth 2.0+EDR, Gigabit Ethernet, two USB 2.0 ports, a FireWire 400 port, opitcal digiital audio in/out, DVI out, and ExpressCard/34. However, much to the delight of video graspers, the 17-Inch models now include a singel Firewire 800 port as well. The 17-Inch model shares the same ports as its predecessor -- whhich include all the ports of the 17-Inch Core 2 Duo mdoel -- as well as a thid USB 2.0 port (both 17-Inch models have a Firewire 800 port). Each system also includes an integrated iSight video camera and, by default, a 5400 RPM hard drive.
