Toshiba Satellite M645-S4055 LED TruBrite 14-Inch Laptop (Black)

Toshiba Satellite M645-S4055 LED TruBrite 14-Inch Laptop (Black) Review



I've used this laptop for over two months now, and it does good at what I need it for: sitting in class typing down notes, web browsing, HDMI out to my big screen tv at home watching HD videos. I also needed something that could hold its own when I finally get Starcraft 2 (yes I know it's out). A cross between portability and power, and not too far off from my HP desktop performance (Intel Core2 Quad @ 2.5 GHz; 8 GB ram; Nvidia Geforce GT 240). My graphical processing needs aren't that high, much of the software I use is from the Windows XP era, so this Toshiba's Geforce GT 330m (which performs slightly worse than the desktop Geforce GT 220, and any gamer will tell you, is *NOT* a gaming card) does its job nicely.

That said, I ran 3dMark06 on this, and got a score of around 5000 or so, can't remember exactly (~14-34 FPS at Proxycon, ~12-22 at Firefly, ~7-32 at Canyon, ~15-25 at Frost, something like that).
Final Fantasy IVX's official benchmarking program gave this a ~760 out of 8000 at 1280x720 resolution. Comparatively my PC got around ~1800 at same resolution. Those are both really poor scores, but then again I don't really have time to play much PC games these days.

Previous reviews have been comparing this laptop to the Asus' new Bamboo ASUS U43JC-X1 14-Inch Bamboo Laptop (10 Hours of Battery Life), but I'll compare to what I considered while still browsing for laptops ASUS Republic of Gamers G51JX-X3 15.6-Inch Gaming Laptop (Blue), This was 1,100 two months ago, but has dropped their price to as low as 1,000 every now and then.

Going by pure functionality, the Asus gaming one wins out in multiple areas:

-- 500 GB HDD @ 7200 RPM (Faster load times)

-- 15.6" Full HD 1920x1080 LED LCD Display; Nvidia GTS 360M Graphics Engine with 1GB DDR5 dedicated VRAM
^ This is where the Asus shines. The GTS 360M is slightly more powerful than the desktop GT 240, not exactly a pure gaming card either but over twice the power of the GT 330M!. 15.6" may be a tiny screen, but to be able to support 1920x1080 means watching Blu-ray quality videos at dot-by-dot pixel accuracy: crisp sharp images. The Toshiba plays 720p videos well but scrunches up 1080p videos making it look a bit fuzzy.

-- 2.0 MegaPixel web camera; I don't know too much about cameras, but my old Sony Ericsson S500i phone has a 2.0 MP camera and takes better pictures than the Toshiba's web camera. Watching myself in the web cam application, there was a lot of noise and it wasn't too clear. The webcam isn't that big of a deal as I don't really use it, but a 2.0 MP resolution web camera should be standard by now.

-- 10-key Numberpad: Frankly, some things are just easier with a numberpad.


So how does this Toshiba laptop hold up compared to that Asus?

-- It's smaller and lighter, it may be a 14" screen but it's pretty thick itself. Granted it's stuffed with lots of integrated goodies like Bluetooth (which the Asus also has). Bluetooth actually inteferes with Wifi frequencies so I normally have it off, but to be able to have the convenience of connecting supporting peripherals is nice.

-- Toshiba's processor is slightly faster; meaning its max Turbo-boost frequency is also higher; higher cpu clock frequencies means less battery life. Wait a minute...
Actually Asus also has an ability (Power4 Gear) to overclock the CPU to at least match the i5 450M frequencies, but again, not something you want to do while away from the power outlet.
Luckily with dynamic frequency clocks and Windows 7's automatic (and adjustable) power management you can underclock to save power.

Continuing on about power consumption, this Toshiba laptop incorporates the fairly new Nvidia Optimus technology. From what I understand about it, the integrated Intel HD Graphics solutions offered by the built-in GPU on the i5 chip is the primary display driver. The Geforce GT 330M takes a backseat and is only supplemental, offering processing power when deemed necessary. "Deemed necessary", that's the problem right there. Occasionally there will be a program out there that is slightly incompatible with Optimus technology because all it sees is the Intel HD Graphic's 64 MB of video memory, and not the 1 GB attached to the GT 330M. This may either cause the program to crash, or run poorly because it doesn't know about the extra GT 330M, therefore cannot utilize it. Other times the program initially runs under the Integrated graphics solution, but crashes when suddenly the Optimus technology realizes it should switch up to the High Performance.

Optimus technology isn't bad, I really like the seemless transition that I didn't see when trying out laptops with AMD Vision technology. When switching between ATI and Intel's integrated solutions, they warn of flashing and blackening of the screen, which in that case is normal during switch. This isn't the case with Optimus, everything works in the background, because rather than two seperate entities like ATI/Intel, it's Intel + Nvidia. Eventually (and hopefully) they'll have it all sorted out.

Examples of Optimus Technology flops:

-- Running Adobe Premiere Pro CS4 under High Performance Nvidia GPU: Program stalls and eats up 25% (one "core") of the i5's total processing power. Had to run under Integrated Graphics in order to use the program.
-- Running the PS2 Emulator PCSX2 0.9.7 under Integrated Graphics will crash as soon as it overflows the 64 MB of video memory (At least that's what I think, or it could be the attempt to switch up, because starting off with the GT 330M I was able to run stable past the crashing point. Final Fantasy X - After the initial Square-Enix logo + Final Fantasy X Project, crashed entering the opening Zanarkand scene, Error message referenced the Intel HD Driver)
-- I can't run Portal, even with the latest Nvidia drivers + Optimus updates. Launching from Steam hl2.exe*32 will appear in task manager for a split second then apparently crash. SAD THERE IS NO CAKE. I will try and try again, some people have managed to get Portal running with Optimus but depended on their integrated hardware.


Other things to talk about in this long review:

-- The Toshiba laptop BIOS has an option to disable multi-core processing. THIS IS NOT TO BE CONFUSED WITH DISABLING HYPER-THREADING. I did not find an option to disable HT, but disabling Multi-core processing will disable both HT, *AND* the one of the logical Cores. Congratulations, this option sends us back to the 2003 era. A single core can easily gets stressed out, disabling HT but keeping dual-cores would only be 2 years backwards, except rather than a 45nm Intel Core 2 Duo, you have a 32nm Intel "Core 2 Duo", which uses up less power and generates less heat. HT may have changed since the days Pentium 4s were using them, but back then they generated more heat and requires additional power and hardware resources. Basically two physical cores is better than a single core with HT.

-- The plastic encasing for the screen is a bit flimsy, it's strong enough that you can grab hold of the laptop with one hand to walk around with, fingers clamped on the side, but the plastic encasing will bend. Don't think the screen itself is bending with it, but I wouldn't want to stress the center "Toshiba" part of the screen too much to find out.

-- The slot loading drive is nice, but no matter what design they make, a DVD disc will always take up the same amount of space going in and out.

-- Both the Toshiba and Asus have the backlit keyboard, not sure which one is brighter, but Toshiba's is bright and normally I find myself turning off the keyboard illumination. One review I read says the Asus' logo on the outward side of the screen lights up too, making is really apparent you're using a high-end laptop. Same with the Toshiba, there's no way to just illuminate the keyboard, have not have the "Satellite" on the lower left hand corner light up.

-- Battery Life: I was able to get little over 3 hours of usage with a full charge while in classes doing very little, 2-3 hours worth of "normal" usage. Full stress of CPU + GPU will have power usage of over 55 Watts/Hour. Since the 6-cell battery they give is rated 48 Wh/Hour, the battery will be depleted before a hour is over. 5 hours is completely "realistic" only if you turn on the laptop, open notepad, set to Eco mode, and do nothing but type one letter every 3 minutes or so. They're practically screaming for you to buy their ~61 Wh/Hour 6-cell battery on their Toshibadirect website. Currently there's a deal going on where you can get ~30% off with two coupons, but it's expiring soon, if not already (This review written Sept 14 2010).


In conclusion, if you're looking for a decent laptop with plenty of features and portability, this is one to check out. Competition is fierce and there's plenty of other laptops that may have just what you need (that Asus Bamboo other reviews are talking about for maximum portability beyond a netbook for one, and like I said before I compared it with the Asus gaming laptop because of its specs + price). Other things you'd need to consider is laptop size, this Toshiba one is a bit on the thick side for a 14", given its internal components. I do admit the Asus Bamboo for 0 after 0 Gift Card is awesome. The comparable Asus' gaming laptop for the around the same 00 price however has nearly all matching or better specifications but is around 2 pounts heavier, bigger, but its screen is best in its class for 15.6".

Just need portability and no need for any games? Get the Asus Bamboo!
Something inbetween? Get this one!
High performance graphical processing needed? Get the Asus Gaming models!
Want to spend rediculous amounts of money on inferior specifications? Get a MacBook Pro!


Thanks for anyone who took the time to read this; I don't regret getting this particular laptop too much, it's basically perfect for what I need. It's just once I start comparing purely from specs rather than what I need.. well you read it!
