The luminance is the same as the contrast, and stays well below 200 cd/m². On average we determined an illumination of 177 cd/m². This is sufficient for use indoors, but very bright surroundings, such as in the sun, won”t be favorable for a dark desktop display.
Dell”s 14 inch notebook is equipped with an Intel Core i3-2310M (2 x 2.1 GHz). The brand new Core i3 dual-core CPU has Hyper-Threading (process 4 threads), but doesn”t have Turbo-Boost. The CPU power consumption lies at a TDP of 35 Watts. Of these the two physical cores require 25 Watts. 10 Watts are required by the integrated Intel HD 3000 graphics solution and the memory controller. Compared to the expensive Core i5 models, such as the i5-2540M, the i3-2310M doesn”t have any support for the AES New Instructions. AES helps with encrypting and decrypting. Dell allows for configurations with a 2540M up to an i7-2620M (dual-core).
As usual there are 4 GB of DDR3 RAM on board, whereby both of the available slots are occupied. For an additional sum the E5420 can be fitted with 2x 4 GB or 1x 4 GB of RAM. The hard drive is a 320 GB HDD from Western Digital (WD3200BEKT-75KA9T0) with a rotational speed of 7200 rpm. An SSD option (128 GB) is also provided by the manufacturer.
The Sandy Bridge Core i3-2310M (2x 2.1 GHz) manages to score as many points in the single-core test in Cinebench R10 Single 32-bit, as the significantly faster clocking i3-380M (2x 2.5GHz from the Arrandale generation (2.769 points). The bigger brother i5-2410M (2.3 GHz, Turbo) scores a better 4.510 points (64-bit).
When it comes to daily work multi-threading is more relevant. The i3-2310M once again scores almost identically in this discipline as the i3-380M (6.233). The 2011 i5-2410M or i5-2520M scored 9.451 and 10.128 points respectively (Cinebench R10 Multi 64-bit). The upshot: The Sandy Bridge Core i3 can already take on its faster clocking Arrandale predecessors with a meager clock speed of 2.1 GHz.
|PCMark Vantage Result||
The benchmark PCMark Vantage determined a score of 4.832 points. This level is below that of older systems with the Core i3-380M (Samsung RV511: 5.432) or the i3-370M (Samsung SF510). The cause of this is the low HDD Sub-Score (2.582 points), which should actually be higher with a 7200 rpm hard disc (fast turning).
The 3DMark2006 benchmark, as an evaluation of the general gaming performance, reached a score of 3.330 points. The 2010 Intel HD generation (also integrated into the CPU), only scored 1.500 points on average (depending on the CPU +/- 200 points). This speaks for an improved gaming performance. The extent of this is described in detail in the article Intel HD Graphics 3000 graphics solution. Also see the data sheet for the HD Graphics 3000.
What is definitely impressive is that currently a dedicated entry level GPU Radeon HD 6470M is only 3% faster (3DMark2006). Less demanding games such as Fifa 11 are smooth with high detail settings. Hardware intensive games such as StarCraft2 or Battlefield: Bad Company 2 have to be set to minimal detail settings though.

The two speakers under the hand resting area only provide mid-frequency sounds. Low frequencies are completely missing. For the requirements of an office laptop, the audio quality is still reasonable though. The maximum volume could be loud enough for a small meeting room, and the small speakers don”t distort at all. Worth praising are the volume buttons on the right next to the keyboard. For the case that the boss comes into the office, the speakers can be deactivated instantly.
|Idle (without WLAN, min brightness)||
|Load (maximum brightness)||
The power consumption shows a big difference between an idle state and a high load (CPU + IGP). This is due to the adaptive power consumption, and the 32nm Lithography (manufacturing process). The idle power consumption of the E5420 lies between 10 Watts (power saving, low brightness) and 15 Watts (maximum performance, maximum brightness).
The load test shows the opposite. A 3DMark2006 (IGP Intel HD 3000) requires 41 Watts. During the stress test the Core i3 consumption comes to 54 Watts. The compact 65 Watt AC adapter (241 grams) is suitably dimensioned for this task.
