TOSHIBA l630-06s power adapter

That is a performance difference of roughly 100%, which is not only measureable but is also noticed clearly when performance-hungry tasks have to be managed. TOSHIBA Equium L40 battery CPU-Z and AMD's System Monitor at most displayed the default clock of 2.1 GHz during the tests. Thus, Turbo mode is not enabled and the specified maximum of 2.6 GHz proves to be useless in this model. Since we also observed this behavior in the Intel model, it seems Samsung omits the Turbo mode on purpose in this model range in order to keep the temperatures in the slim case within a limit. Approximately 20% higher results are achieved by Samsung's 14-inch 535U4C (with Turbo) in the CB single-thread tests. TOSHIBA Mini NB505 battery with charger

The section "System Performance" deals with the system as a whole, i.e. how the single core components work together. In addition to the processor's performance, the RAM configuration, storage devices and of course the graphics card play a role. While every new laptop can deal with basic tasks, such as browsing, word processing, playing videos and checking emails, a somewhat stronger system is needed for higher demands, like image editing and converting. TOSHIBA L40 power adapter

The standard benchmarks, such as PCMark Vantage (2561 points) and PCMark 7 (1368 points), show that the performance is clearly higher than that of netbooks (e.g. Asus Eee PC 1011CX), but over half as weak as the Series 5 alternative featuring Intel's Core i5-3317U CPU. As long as you are not planning to perform loads of conversions, the above mentioned tasks can be performed comfortably and easily. TOSHIBA Qosmio F40 battery with charger

However, if you want to occasionally convert a bit of music or videos into a different format, you will have to count with a longer timeframe than would be the case with stronger processors and graphics chips. iTunes conversion from MP3 to AAC format was performed in 17.9x speed and the conversion of our two test videos took roughly twice as long as with the AMD's A6-3420M processor.

In contrast to Samsung's Series 5 530U3C-A01DE, Hitachi's conventional hard drive is not supported by a 24GB Express Cache. TOSHIBA A60 battery The transfer rates (max. 110 MB/s) and the access times (21 ms) are within the usual range and correspond to the current expectations placed on hard drives featuring a revolution speed of 5400 rpm. Should speed be more important than storage, replacing the HDD with a solid state drive could increase routine speed noticeably. A comparison of storage devices can be found in our extensive HDD benchmark list. TOSHIBA c650-15z battery

Until now, integrated graphics solutions from AMD and Nvidia often had an advantage over the competition from Intel. TOSHIBA c650-17n battery This is only true to an extent in this case, even when we only compare the graphics performance directly because the differences between the Series 5 alternatives are too insignificant. On the one hand, the processor integrated graphics solutions are innately not very strong. TOSHIBA c650-19j power adapter

On the other hand, our Radeon HD 7500G graphics core does not reach the maximum clock rate of 424 MHz, but stays at 200 MHz, particularly with simultaneous CPU load, according to AMD's System Monitor and GPU-Z. At least the performance is not throttled even more on battery power. It works just like in AC-mode with the right pre-settings in AMD's Powerplay settings. TOSHIBA c650d-112 battery

As to the benchmarks, the results of both models are basically quite close. It is only striking that the AMD configuration clearly wins Cinebench R11.5 OpenGL shading with 20.5:13.7 points but then is defeated by Samsung's Series 5 530U3C-A01DE (Intel HD Graphics) in 3DMark Vantage with 2410:2854 points. This might be because OpenGL Shading is not quite as CPU-heavy and the graphics card can run on its full clock. TOSHIBA c655-s5056 battery with charger

In practice the measurable differences are hardly noticed. TOSHIBA l635-s3012rd battery Both models can render Full HD videos smoothly and 3D graphics power is rather secondary for Office and other application fields. Photoshop filters that use OpenCL are still very manageable and, as we noted in "System Performance", the graphics chip is usable for converting, providing that the software supports it. It again gets interesting in games since certain obstacles have to be tackled so that the user perceives the track as smooth. TOSHIBA l630-06s power adapter

A shared graphics memory, a fairly low GPU maximum clock speed of 424 MHz and "merely" 256 shader cores are not the best conditions for a good gaming performance. Then there is the weak CPU that does not exactly improve things. We selected a few games that only cover a small range, TOSHIBA l635-s3020wh battery but still allow insight about how well our test device really copes in this regard. As our result table shows, low quality settings and a low resolution are possible when you do not want to watch a slide show. It seems that only the restrained World of Warcraft enables a bit more. An extensive comparison chart about the gaming performance of graphics cards can be found here. TOSHIBA l645d-s4029 battery with charger

Samsung's 535 noise development has to be described as extremely pleasant. TOSHIBA l645d-s4036 power adapter The very quiet fan remained completely disabled in Silent Mode during low load and the quiet hard drive noise of 31.6 dB(A) was audible when the storage device was being accessed. If an SSD was installed, the test model would be silent. The system even stayed agreeably quiet with 32.1 dB(A) when several browser tabs were opened or while uploading image files or installing programs. The fan noise first increased to 39.8 dB(A) to 42.3 dB(A) during demanding tasks, such as converting music and videos or gaming. However, it is never annoying due to the restrained noise characteristics. We did not ascertain high-pitched noises, whistling or a hectic fan management in our test device. TOSHIBA l645d-s4037bn power adapter

The fan's low activity in Silent Mode causes the casing to heat up to approx. 40°C. TOSHIBA l650-13m power adapter That is not unpleasant or critical, but it is very noticeable in some places and thus far from being a cool laptop. However, it is possible to select a constantly whirring fan in the Eco Mode settings, which lets the case's temperature drop by 2°C. During load the casing reached a temperature of up to 52.2°C at the vent and up to 47.7°C on the bottom in the same area. That is quite warm and shows that the cooling system works at the limits of its possibilities during longer periods of load. Samsung likely did not enable a higher CPU clock in this series (disabled Turbo) for good reason. TOSHIBA l650-19w battery

The sound output comes from two small speakers on the bottom and only supplies the most necessary. TOSHIBA l655-11g battery with charger You do not want to torture yourself for a long time with a very treble-heavy and tinny sound that lacks real mid-ranges and bass. Headphones or external speakers perform miracles in a direct comparison. They enhance the sound quality immediately and will quickly end up as accessories in your laptop case. If you require a headset for video calls or other tasks, you will only find a combo audio jack. Headsets featuring 2 jack plugs cannot be used and will have to be replaced. TOSHIBA l670-10r battery

The power consumption at the mains ranges from a minimum of 7.7 watts up to a maximum of 41.8 watts. TOSHIBA l670d-103 battery with charger Even up to 42.4 watts is possible when the battery is being charged at the same time. While the minimum consumption indicates that AMD manages the low load consumption well, the maximum power requirement seems to be a bit high for a system featuring a 17 watt TDP APU. TOSHIBA l670d-105 battery

Especially since the PSU is specified with a nominal power usage of merely 40 watts. Another indication that Samsung purposely omitted Turbo in the CPU is that the maximum is already permanently being squeezed out during full load. The quite optimistic power consumption display in Samsung's Easy Settings should not be trusted too much. The displayed rates differ by more than 10 watts compared to what our power meter recorded. TOSHIBA l670d-bt2n22 power adapter

In addition to the power consumption, a high battery capacity is needed for a good battery runtime. Samsung opted for a permanently built-in alternative in its slim Series 5 models. In our case, it still features a good capacity of 45 Wh. A version featuring a 66 Wh battery is also listed in the data sheet. TOSHIBA l670d-st2n02 battery

Almost 7 hours of runtime was reached in BatteryEater's Reader's test (minimum screen brightness, all off, energy-savings mode), TOSHIBA l675d-s7019 battery with charger which results in a power consumption of 6.4 watts. This is due to certain power saving features of some components on battery power, among other things. We did not ascertain longer battery runtimes when Samsung's Eco Mode was selected. The Eco Mode did not exhibit a runtime plus opposed to the system's energy-saving mode in our Wi-Fi test where the brightness was set to approx. 150 cd/m2 and enabled Wi-Fi module. On the other hand, the "Optimized Samsung Mode" did not have an apparent impact on the system's performance either. We recorded virtually identical performance and runtime rates compared with Windows' high-performance profile. TOSHIBA m505-s4990-t battery

The battery runtime in BatteryEater's Classic test (maximum brightness, all on) was 92 minutes with a rest capacity of 3%. This adds up to a consumption of approx. 30 watts. We played a movie file directly from the hard drive in our video test because there is no optical drive. This was possible for over 2 1/2 hours using energy-saving mode, disabled Wi-Fi and maximum brightness. TOSHIBA m645-s4049 power adapter

Samsung's Series 5 scion featuring AMD technology clearly lines in behind the Intel-based versions in terms of performance and is only half as fast in many cases. The somewhat better graphics performance in the subareas does not help here either. It does not have a positive impact on the subjective speed disadvantage in practical use. TOSHIBA m645-s4055 battery with charger

In return, we did not ascertain any differences to the Intel model regarding casing quality, connectivity, screen or keyboard qualities. There may be the odd, minor production-related deviations, but they are not connected to the single processor configuration. TOSHIBA pro c650-125 battery

The battery runtimes do not reach the times of Samsung's Series 5 530U3C-A01DE (Intel) despite the weaker computing power, but they are nevertheless quite useable and enable working away from the mains for about 4 hours. TOSHIBA pro c650-13d battery with charger

The casing's temperature and noise development are roughly on a par with the Intel model. However, the AMD combination is a bit quieter and virtually works silently in little load. TOSHIBA pro c650-18d battery

For currently just under 600 Euros (~$776), you have to accept lower computing power and approx. 1 hour less of practical runtime in Samsung's Series 5 535U3C (AMD). In return, you get a lightweight, slim and above all quiet subnotebook that is well suitable for many common home office tasks. TOSHIBA pro c650-18e power adapter
