The ProBook 6560-LG658EA is a 15.6 inch laptop from Hewlett Packard that is equipped with special business features. Not only the inner values count to this, but the modern design as well. The display bezel is made of pearl blasted aluminum. The case is additionally reinforced with magnesium. The 39.6 cm HD display (15.6 inch) in a 16:9 format can reproduce a resolution of 1600x900 pixels. Thus, it is also perfectly suitable to work with several adjacently opened windows.

An Intel dual core CPU, model Core i5 2520M, works inside the entry level business laptop. It runs with a clock rate of 2.5 GHz and can even overclock single cores up to 3.2 GHz thanks to the Turbo Boost technology. Besides the incorporated Intel graphics, this notebook also has a dedicated graphics card from AMD. The Radeon HD 6470M supplies its own video memory of 512 MBs.

Moreover, a 500 GB hard disk, a DVD burner and 4 GB of RAM are installed. HP has also integrated WWAN (3G) and a 56k V9.92 modem next to WLAN, Bluetooth and Gigabit LAN for connectivity in our test model.

An Intel Core i5 processor from the Sandy Bridge generation is used in the HP ProBook 6560b-LG658EA. The dual core CPU (Intel Core i5-2520M) works with a base clock of 2.5 GHz. The number of computing cores is virtually doubled (4) thanks to Hyper Threading support. The CPU is automatically clocked up to 3.2 GHz by the Turbo Boost mode when required. The processor has a 3 MB level 3 cache and is produced in the 32 nm technology.

The Sandy Bridge dual core processor also includes the incorporated DirectX 10 capable Intel HD Graphics 3000 graphics card and the memory controller in the specified TDP of 35 watts. Besides the CPU's HD graphics, a dedicated graphics, model AMD Radeon HD 6470M, is also used in the ProBook.

CPU Performance
The 2520M CPU's maximum clock rage of up to 3.2 GHz also remains stable during load (Cinebench's single CPU rendering). That means it exploits its turbo reserves well. The CPU's clock stayed constant at at least 2.5 GHz in our simulated stress test over 180 minutes – both Prime and Furmark ran simultaneously.
Turbo also pushed the CPU rate to its limits of 3.2 GHz in the first few minutes. The hotter the die temperature got, the less "turbo" was used. However, the Intel Core i5-2520M 's clock rate never fell below 2.5 GHz, so the specified base clock of all cores, during load.

The achieved results in the Cinebench R10 benchmark tests are within the expected range for the used CPU in both the single core as well as in the multi core rendering test.

System Performance
This laptop was no exception and had to run through many tests in the benchmark marathon. The total package (CPU, GPU, memory and hard disk) are assessed with cross component test tools, such as PCMark05, PCMark 7 and PC Mark Vantage.
Moreover, the notebook had to endure a few synthetic benchmarks, among others from Futuremark. These test tools specify just how fast the laptop's graphic functions are. This is only secondary in a business notebook, but this point shouldn't be underestimated. In particular since many applications can benefit from the resources of a dedicated GPU.

The device achieved a score of 7680 points in PCMark Vantage. Thus it is in the upper range of all notebooks that we have tested without a built-in solid state drive (SSD). Our experience shows that they would push the total score to over 10000 points. This would also be a possibility for the user to increase the 6560b's application performance considerably after buying.
In comparison, the HP Elitebook 8460p (2620M/HD6470M) places itself insignificantly higher, the workstation from the previous Elitebook generation, the 8540w (620M/FX880M) lags even slightly behind with 7510 points.
