Hp Refurbished 14" ProBook 645/640 4GB RAM 320GB ROM - Black

Refurbished 14" HP ProBook 645/640 4GB RAM 320GB ROM     HP offers 14-inch sized business laptops in the ProBook 645/640 product line. Their computing power is absolutely sufficient for managing most tasks in the office, Internet, and communication field. They also feature classic business features, such as a docking port  

An A6 APU does its job in the ProBook. It is based on the Richland architecture. The APU's CPU part is a dual-core processor that clocks with a base rate of 2.9 GHz. The speed can be boosted up to 3.5 GHz via Turbo. AMD specifies the APU's TDP with 35 watts.

The CPU's full performance is available in both AC and battery mode. The processor ran the single-thread tests of the Cinebench benchmarks with 3.5 GHz (both cores), and the multi-thread tests with 3.3 GHz (both cores). The ProBook cannot match the scores of either the latitude or Thinkpad Their Intel processors are significantly stronger.

 

Graphics Card

AMD's  graphics core is used in the ProBook. The GPU supports DirectX 11 and has a base clock of 533 MHz. Its speed can be boosted to 720 MHz via Turbo. The graphics core's power is on par with Intel's HD graphics 4400 GPU. Neither contender can compete with the Latitude. The GeForce graphics core is significantly stronger.

Gaming Performance

The ProBook's CPU-GPU combination enables playing a few games in a low resolution and with low quality settings. Higher resolutions or a higher quality setting should also be possible in single cases, for example, in the game FIFA 14. A few additional frames can be squeezed out of the hardware when a second working memory module is installed. The memory then runs in the dual-channel mode, and the graphics core is maxed out better. Thus, the frame rates increase - depending on each game - by an average of up to 20%.
