While the market for mobile multimedia computers dominate home laptops and ultra-small netbooks to choose a practical low-cost multifunctional working laptop is not easy. The devices meet all these requirements, there are infrequent. In this review, we just consider one of these laptops – Lenovo ThinkPad Edge 15.
Chinese manufacturer Lenovo is famous for its excellent series ThinkPad, focused on the corporate market. But for all its many merits of this line of laptops are an expensive pleasure and not everyone can afford. That’s why Lenovo has released a subseries Edge, the most simplified and less expensive, but remains an excellent working tool.
Box Lenovo ThinkPad Edge 15 is the same as that of the full ThinkPad’ov – from a simple gray cardboard, without any handles for easy transport. Despite the similarity of the packages supplied with Lenovo ThinkPad Edge 15 was a bit easier:
• Notebook (2250 g);
• 6-cell battery pack (310 g);
• power adapter + power cord (330 g);
• instructions for setting up;
• guidance on maintenance and troubleshooting.
The operating system is a laptop running Windows 7 Home Basic (32-bit, RUS). This is done primarily to reduce costs. Also in the sale you can find this model and does not have an operating system that will make the unit price even lower. Disk recovery software environment in bundled Lenovo ThinkPad Edge 15 is not, a copy of the operating system pre-installed software is a special hidden partition on your hard drive. Speaking of preinstalled software can note a very useful utility ThinkVantage Update, which tracks the relevance of established brand-name programs and device drivers and automatically updates them when new versions.
PERFORMANCE
Notebook Lenovo ThinkPad Edge 15 is based on dual-core Core i3 with an index of 350M. Each of its core is clocked at 2260 MHz. Like all the processors Core i3, it lacks technology Intel Turbo Boost. Third level cache is 3 MB. Maximum termopaket – 35W. The processor supports Enhanced Intel SpeedStep, Idle State, Execute Disable Bit, Intel 64 Architecture, as well as Intel Virtualization and Trusted Execution. In Core i3 350M guided by a full set of SIMD-instructions: MMX, SSE, SSE2, SSE3, SSSE3, SSE 4.1, SSE 4.2.
The new processors are built on the core Arrandale, made at rates of 32-nm process technology, are built into the processor graphic core Intel GMA HD and memory controller.
Established processor offers excellent performance. It is perfectly handle like a normal office routine, and Web surfing, and the more serious calculations.
As a control chip set is selected chipset Intel HM55. The processor has taken the lion’s share of the responsibilities of the north bridge (built-in graphics core and memory controller), so the functions in Intel HM55 not so much. From the basic and most important can be identified built-in sound core Intel High Definition (HD) Audio, support network controller with a maximum speed of up to 1000 Mbit / s and the ability to switch between discrete and integrated system, but the last chance to Lenovo ThinkPad Edge 15 is technically not yet implemented.
Memory Notebook Lenovo ThinkPad Edge 15 consists of a single strip of memory standard, DDR3-1066 and 2 GB (Micron 16JSF25664HZ-1G1F1).
Memory for DDR3 compared to the previous consumes 40% less energy, but also has an 8-bit prefetch buffer, whereas DDR2 memory in it 4-bit and DDR memory and a 2-bit at all. Prefetch buffer (prefetch buffer), it should be noted, quite an important element in modern memory, since he is responsible for caching data before they will be in demand. Another advantage of DDR3 can be considered a new dynamic on-chip termination circuitry (Dynamic On-Die Termination), which is calibrated in the initialization process to achieve optimal interaction and system memory. DDR3 vs. DDR2 minus can only be called a higher latency, but it is offset by higher operating frequency.
Lack of RAM will be felt when working with various graphic editors, well, in most cases, 2 GB installed for normal operation should be sufficient. You can increase the amount of RAM in addition to do it on their own will be quite simple: it is only necessary to buy another memory corresponding to the bar and set it free in the second slot SO-DIMM.
Video
Video Notebook Lenovo ThinkPad Edge 15 shows a discrete graphics card ATI Mobility Radeon HD 545v. This graphics card is not new. The basis for this graphics card was the HD 4570. ATI Mobility Radeon 545v uses the graphics chip is M92 (55 nm), a system of 80 standardized 5-dimensional shaders. Bus for such a decision is 64-bit. There is support for memory GDDR3, DDR3, DDR2. This modification uses 512 MB of internal memory standard GDDR3. At the expense of total system memory memory capacity increases up to 1242 MB. Card supports DirectX only to 10.1 and Shader – 4.1.
Test results for ATI Mobility Radeon HD 545v displayed as a table, where in addition to our video presents a number of discrete and embedded solutions from different vendors.
