Lenovo's Z50-70-series consists of several black and white models, but there are several different combinations of CPUs, graphics cards, memory and storage drives. A complete list would go beyond the scope of this review. Looking at the product range of a major mail order company, there are the Kaveri models AMD A10-7300(4x 1.9-3.2 GHz, TDP 19 W) and A8-7100(4x 1.8-3.0 GHz, TDP 19 W) that are combined with an AMD Radeon R7 M255(2 GB). If you prefer Intel processors, you can combine i3, i5 and i7 Haswell processors with the dedicated graphics cards Nvidia GeForce 820M and 840M. SSDs are not available; Lenovo uses conventional drives or hybrid drives with 8 GB SSD cache and a capacity between 500 GB and 1,000 GB instead. The memory equipment is between 4 and 8 GB. Some retailers also list configurations with the 1366x768 resolution, but we could not find any evidence for that. We expect that every local Z50-70 model uses the glossy TN Full HD panel from our review sample that is equipped with a fast Intel Core i7-4510U(2x 2.0-3.1 GHz, Hyper-Threading, TDP 15 W), 8 GB RAM, a dedicated Nvidia GeForce 840M graphics card as well as a 1 TB hybrid hard drive.
The comparison devices for our review unit are similar in regard to the hardware equipment and price. The MSI GP60-2PEi585 that we reviewed in June 2014 uses an Intel Core i5-4200H(2x 2.8-3.4 GHz, Hyper-Threading, TDP 47 W) and the same GPU, but only with 2 instead of 4 GB dedicated memory. The Acer Aspire V5-561G, however, uses a combination of Intel Core i5-4200U(2x 1.6-2.6 GHz, Hyper-Threading, TDP 15 W) and AMD Radeon R7 M265 graphics card. All three notebooks in our comparison have TN displays with 1920x1080 pixels, but the two rivals from MSI and Acer have matte surfaces and conventional hard drives without an SSD cache
