Acer Aspire 5670 Series Review (pics, specs)
by Andrew Johnson, Alaska USA
Overview and Introduction:
The Acer 5670 is one of the first notebooks featuring Intel’s impressive new Centrino Duo processor which has two cores to offer significant performance gains. It has a sharp 15.4″
wide aspect screen putting it in the mid-sized desktop replacement category. It’s also loaded with extras such as Bluetooth, a sleek slot-load DVD burner and a built in webcam, which, along with the ATI mobility X1400 graphics and of Ram 1GB plus a 100GB 5400 RPM SATA hard drive make for a pretty impressive machine.

Build & Design:

The Acer 5670 is in clad silver painted plastic and a combination of glossy and flat black plastic. It’s not thin, but it’s not bulky either. It is a fairly solid notebook with decent hinges for the screen. There is some flex but nothing alarming. Only a hard press on the rear of the screen will cause ripples to appear. I like the slot-loading dvd burner which looks sleek and avoids potential damage.
The 15.4″ WXGA «CrystalBrite» LCD is glossy and spectacular. It is bright, with high contrast, saturated colors and even illumination. The viewing angle is very good to the sides and falls off more quickly to the top and bottom like most laptops. Response time is rated at 16ms which should eliminate ghosting even in high speed gaming.

The screen is about normal brightness for a high quality notebook. I had to turn the brightness down to get a correct exposure in a bright room — five 60 watt light bulbs hung in a chandelier above the notebook photographed on my floor.
As with all glossy screens, reflections of lights can become annoying to some. Your eyes, like my camera, can usually focus on the screen rather than the reflection as shown here, like this:

The speakers on the front of the notebook put out a decent level of crisp sound that is about par for notebooks, but still sounds tinny with no bass.
Processor and Performance / Benchmarks:
Just what can be expected from Intel’s advanced new Centrino Duo chip? It has twice as many cores, so is it twice as fast? Sometimes, but usually the benefit is smaller. However, while most benchmarks won’t show a twofold increase in speed, heavy multi-taskers will immediately notice a significant boost in overall system responsiveness. Tasks that would normally cause a major slowdown on a single core machine (like running super-pi or rendering a video) seem as if they’re not even running, because the computer is ready and available for your other input on another program.
For a single program to take advantage of two processor cores, it has to be specially programmed. More and more software is being written this way, and for now at least most high end software that is likely to make you wait in the first place is. Video and software Photo is often «multi=processor aware.» Being a photographer, I spend many hours using Adobe Photoshop. While I believe even older computers are more than fast enough for most tasks, it will be a long time before Photoshop’s need for speed is satisfied. Why wait 60 seconds when you can wait 1? Or none?
I compared the Acer 5670 to my Dell 9300 in common Photoshop tasks real photographers do, not wacky filters that might make an Apple seem super fast. The Acer’s clock speed is only about 4% faster than the Dell, so I thought it was a fair indication of the performance gains possible with a dual core CPU. Both machines had 1GB of ram, and the Dell has a faster hard drive (7200 RPM vs. 5400 RPM)
While the tests are not all inclusive, it represents some of the things I am commonly waiting on the computer for, and illustrates the potential performance gains dual core CPUs offer.
Test 1: Average time to convert a 16.7 megapixel raw files to Tiff using Adobe Camera Raw 3.3
Acer Core Duo 1.66 GHz. 12 seconds
Dell Pentium M 1.6 GHz. 22 seconds
Here the dual core is almost 85% швидше!
Test 2: Unsharp Mask a 16.7 megapixel digital image.
Acer Core Duo 1.66 GHz. .7 seconds
Dell Pentium M 1.6 GHz. 1.2 seconds
Again very significant speed gains with the dual core.
Test 3: Resize a 16.7 megapixel image to 20×30 inches at 300 DPI
Acer Core Duo 1.66 GHz: 2.0 seconds
Dell Pentium M 1.6 GHz. 4.2 seconds
Whoa! Over twice as fast! I’ll have to up my hourly rate.
Test 4: Convert 16.7 megapixel digital image to CMYK color
Acer Core Duo 1.66 GHz. 4.4 seconds
Dell Pentium M 1.6 GHz. 9.4 seconds
I ran the popular Super Pi benchmark once by itself and got a result of 1m 22s. This was just slightly slower than the 2.0 GHz Core Duo Super Pi times:
