MagyarDell Latitude E5550 (Broadwell) Notebook Review Update
For the original German review, see here.
Dell’s Latitude E5550 series offers the business user a 15.6-inch notebook in the mid-price range with features like a docking port, TPM, and a fingerprint reader. Just a few weeks ago, we tested a Haswell-equipped version of the Latitude E5550 that achieved a "good" rating (86 percent). We looked again at the E550 in another test, this time with Intel's brand new Broadwell CPU, to see if the system benefits from the new processor.
The HP Probook 650 and the Probook 655, the Lenovo Thinkpad L540, and the Fujitsu Lifebook E554 — all mid-priced business notebooks — are the Latitude's competitors.
Since both the Broadwell and Haswell E5550 use the same design, we will not cover case, connectivity, input devices and speakers here. This information is available in our Haswell model review.
Display
Dell equipped the Latitude with a matte 15.6 inch display with a native resolution of 1920 x 1080 pixels. The display delivers a good brightness of 295 cd/m² that its competitors — like the HP Probook 650 (264.4 cd/m²; Full-HD) and the Fujitsu Lifebook E554 (230.7 cd/m²; Full-HD) — cannot match.

* ... smaller is better
Contrast (589:1) and black value (0.53 cd/m²) are alright, but not outstanding. The Fujitsu Lifebook E554's display (816:1; 0.31 cd/m²) delivers better values, while the HP Probook 650 (299:1; 0.9 cd/m²) falls behind its competition. The Latitude's display cannot achieve either full sRGB or AdobeRGB: it manages about 62 percent of the AdobeRGB color space and 82 percent of sRGB. But since the average DeltaE-2000 difference is 4.32, the E550 screen only marginally (at a DeltaE of less than 3) misses the target range. The screen also does not exhibit a bluish cast.
Like the HP Probook 650 and the Fujitsu Lifebook E554, the Latitude also comes with an IPS panel that allows you to read the display from any angle. Thanks to the matte display surface and the sufficient brightness, the notebook can also be used outdoors.
Performance
The Latitude E5550’s processor delivers sufficient performance for everyday tasks. The notebook comes with standard business features like TPM, a docking port, and a fingerprint reader. Our test model is ready for an LTE modem. The Latitude can be individually configured. At test time, entry level models of the computer were available from 680 Euro (770 USD). Our test model is priced just under 1000 Euro (1100 USD).
Processor
Intel's new Broadwell Core i5-5300U dual core processor CPU with a 2.3 GHz base clock drives the Latitude. Thanks to turbo technology, the clock rate can go up to 2.7 GHz (both cores) or 2.9 GHz (only one core). In both AC and battery operation, the processors ran at maximum speed in the Cinebench benchmarks. The Core i5-5300U supports hyperthreading (each core can run two threads). Intel specifies a TDP of 15 watts for the processor. Haswell ULV CPUs have the same TDP.
The i5-5300U CPU is the successor of the Core i5-4300U. While the Core i5-5300U uses a higher base clock (1.9 GHz vs. 2.3 GHz), the turbo clocks are almost the same (Core i5-4300U: 2.6 GHz/2.9 GHz; Core i5-5300U: 2.7 GHz/2.9 GHz). Improvements in the Broadwell architecture ensure that the Core i5-5300 achieves slightly better results than the Core i5-4300U processor. Our benchmark tests showed a performance gain of about 5 to 10 percent.

System Performance
The powerful Core i5 processor and the solid state disk ensure a fast system: Windows boots swiftly, and the PC Mark benchmark results were very good. It surprised us that the Latitude performs better than its Fujitsu Lifebook E554 and HP Probook 650 competitors. Both the Fujitsu and the HP use standard volt CPUs (no ULV), which improves performance. The Latitude’s superior performance was likely due to its SSD , which delivers slightly higher 4k read and write rates than the models used in its competitors.

Storage Devices
The Latitude is equipped with a 2.5 inch solid state disk from Samsung with a capacity of 128 GB (with only about 87 GB available to the user). Its read rates are good, but the write rates are not the best. This disk can easily be replaced with not only a higher capacity model (note: only SSDs with a height of 7 mm will fit), but a faster one (e.g., the Samsung SSD 840 Evo).

Graphics Card
Intel's HD Graphics 5500 GPU is responsible for graphics output. The core supports DirectX 11.2 and clocks at up to 900 MHz. The HD Graphics 5500 is the successor of the HD Graphics 4400, but has a slightly lower clock rate (900 MHz vs. 1100 MHz) in spite of additional execution units and a bigger L1 cache. In 3D Mark benchmark tests it performed slightly better than the HD Graphics 4400. The graphics performance of the Latitude could be better. If the computer is equipped with a second RAM module, the RAM works in dual channel mode, allowing the GPU to be used more efficiently and achieve better results. This modification on our test model gave us increased (by 16 percent) 3D Mark 2011 results. All of the Latitude's single channel and dual channel results are listed in the comparison table.

Gaming Performance
The Latitude's CPU-GPU combination can run several games smoothly with low resolution and low quality settings. On average, the notebook achieves slightly higher frame rates than comparable computers of the Haswell ULV (Core i5-4300U/4310U; HD Graphics 4400) hardware generation. The Latitude cannot keep up with competitors like the Lifebook E554 and the Probook 650. both of which benefit from their more powerful processors and RAM that works in dual channel mode. The addition of a second RAM module in the Latitude levels the playing field, giving the RAM the ability to work in dual channel mode and increasing frame rates by 20 percent on average. The Lifebook and the Probook will still perform slightly better, however, in very CPU-intensive games.

Emissions
System Noise
Usually, the Latitude is silent while idle since the fans don't run most of the time. The Fujitsu Lifebook E554 and the HP Probook 650 are no different; and all of the fans in our comparison group did not speed up before load is applied. The Latitude was the loudest in our stress test. On the positive side: the fan does not generate any annoying whistling, buzzing or whirring noises.

Temperature
The Latitude completed the stress test (Prime95 and Furmark running simultaneously for at least an hour) in the same way in both AC and battery power mode. The processor and graphics cores ran at maximum speed (CPU: 2.7 GHz; GPU: 900 MHz). The notebook did not grow particularly warm. We measured a temperature of over 40 °C (104 °F) in two spots during the stress test.
(±) The maximum temperature on the upper side is 42.3 °C / 108 F, compared to the average of 34.2 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(-) The bottom heats up to a maximum of 48 °C / 118 F, compared to the average of 36.7 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 29 °C / 84 F, compared to the device average of 29.5 °C / 85 F.

Energy Management
Power Consumption
While idle, the Broadwell Latitude needs less energy than its Haswell sister model. Under full load, however, the power consumption is slightly higher. This is not surprising since the Broadwell Latitude is, overall, more powerful. Its Fujitsu Lifebook E554 and HP Probook 650 competitors, both with conventional mobile processors, need significantly more energy under full load.

Battery Life
The battery, while the Latitude is idle, lasts 12:01 h. The Fujitsu Lifebook E554 (16:28 h) performs significantly better. We tested the idle scenario (minimum display brightness, active energy saving profile, and disabled radio modules) using the Battery Eater Reader test. Under load (running the Battery Eater Classic test at maximum display brightness, maximum performance profile and enabled radio modules), the Latitude shuts down after 1:06 h. Again, the Lifebook (1:37 h) lasts longer.
The Dell notebook finished our realistic WLAN test after 6:21 h. The Lifebook (at 6:22 h) is on par, but the HP Probook 650 (4:18 h) is not. The test simulates web browsing with a script that refreshes websites every 40 seconds with the following additional system demands: active energy-saving mode; display brightness adjusted to around 150 cd/m²; a loop of the short movie Big Buck Bunny (H.264 coding, 1920 x 1080 pixels) to determine the battery runtime during video playback; wireless modules deactivated; display brightness adjusted to around 150 cd/m². The Latitude lasted 6:27 h; the Lifebook survived for only 5:43 h.
Overall, the Latitude delivers good battery runtimes and performs only slightly better than its Haswell sister model despite its better performance in other areas and the same battery capacity.

Verdict
The Dell Latitude E5550 is a 15.6-inch notebook that delivers performance sufficient for everyday business tasks. It works quietly most of the time and provides good battery runtimes. Thanks to a solid state disk, the notebook boots swiftly and works quickly. In addition, it has good input devices and a bright IPS display. The display contrast should be better. A big maintenance hatch allows easy access to the hardware. Furthermore, the device comes with the usual business features like docking port, TPM, and fingerprint reader. Our test model is LTE/3G-ready, too: an LTE compatible modem can be ordered from Dell for just under 60 Euro/70 USD.
All in all, Dell has produced a balanced device without any serious weaknesses. Overall, the Broadwell processor is a good start. Compared to the Haswell CPU, it performs slightly better without a negative impact on battery life. Those who need even better performance should select one of the Latitude's competitors, like the Fujitsu Lifebook E554 or the HP Probook 650, both of which come with conventional, but more powerful, mobile processors.
Note: Although the Broadwell Latitude is slightly more powerful and achieves slightly better battery runtimes than the recently reviewed Haswell Latitude, the latter achieved a higher rating of 86 percent. Why? First of all, the Broadwell Latitude lacks the LTE modem present in the Haswell Latitude. In addition, it is louder under full load and gets overall warmer than the Haswell model.
