Who says low-end has no market? When "tall, rich, and handsome" becomes a new term for a different class, those Macbook Airs SUPREMEFIRE inlaid with gold and diamonds, and extremely high-end Dell Alienware extraterrestrial madmen, under the dazzling halo of various high-end and luxurious configurations, there are models priced under 3000 yuan with plain makeup, Pentium B9 core, Celeron B8 core, Core i3 core HD 3000 integrated graphics, AMD E/C series models buried in the corners of the market, these low-end products are so unobtrusive and even dim. For entry-level users who seek practicality at a low price mainly for daily internet entertainment and working-class people, this article first compares the low-end configurations and performance differences within 3000 yuan, then recommends and introduces low-priced integrated graphics and discrete graphics products.

Test of Celeron B815 integrated graphics based on Sandy Bridge architecture. Like the positioning of netbooks, Brazos APU's low-power design is especially aimed at high-definition video books, online entertainment, and portable devices, clearly not for mainstream performance. Although Brazos APU was born at an inappropriate time during the decline of netbooks, in terms of data processing performance, compared to APU A series processors, Brazos APU is really too weak. However, with only 18W power consumption (including GPU), Brazos APU E/C series processors can perfectly realize high-definition videos and surpass Atom as well as the combination with ION in all aspects. Undoubtedly, Radeon HD 6320/6310 graphics cores paired with Bobcat architecture are also a perfect combination, basically able to handle mainstream high-definition videos, online entertainment, and even some 3D games at entry-level settings, faster than most current integrated graphics cards, and even comparable to Sandy Bridge architecture's HD Graphics 3000 under DirectX 11 features. Is this not enough?

AMD APU E-450 (integrated graphics): 1024x768 (left), 1280x768 (right). Therefore, in terms of market division, the performance below 3000 yuan can be divided like this when purely discussing integrated graphics: Core i3 integrated graphics > Pentium B9 core integrated graphics > Celeron B815 integrated graphics > APU E-450. Due to the low-power design of Brazos APU series processors, from the 3DMark06 test results, it is almost equal to the test performance of Celeron B815, with little difference between the two. Although the main frequency of APU E/C series is lower, adding a discrete graphics card configuration can greatly reduce the data pressure on the CPU's graphic performance.

On the other hand, within the 3000 yuan price range, selecting integrated graphics models is more balanced and matched. However, in addition to many integrated graphics models, various notebook manufacturers have also launched quite a few discrete graphics models to enhance performance, such as Pentium B9 core paired with GT 540M, HD 6370M, APU E-450/E-350 paired with HD 6470M discrete graphics cards, etc., which significantly improve performance. Below is the configuration price table of five products introduced in this article within 3000 yuan.

Through 3Dmark06 performance testing of Celeron Dual-Core B815, since the test includes a comprehensive presentation of the graphics card and processor, it can also serve as a reference for daily application needs. In the Core i3+HD3000 integrated graphics test (default resolution of 1280x768), the score is about 3600 points, Pentium Dual-Core B940+HD3000 integrated graphics scores around 3100 points, and this Celeron Dual-Core B815 scores 2911 points, showing a very clear step-by-step distinction. Under the Sandy Bridge architecture, performance ratios can be roughly calculated as follows: Celeron B815 = 80% x Pentium B940 = 72% x Core i3 (core graphics).

Careful friends will find that since the Celeron B815 dual-core processor continues the Sandy Bridge architecture, compared to Core i-series, the disadvantages of the dual-core Celeron B815 are the lack of support for AVX instruction sets and the reduction of L3 cache. Compared to its "hardship brothers" Pentium dual-core B9 series, many specifications are very similar, such as both having 2MB L3 cache, GPU graphics core frequency of 650-1050MHz (Pentium B9 series GPU dynamic frequency is 650-1100MHz, slightly higher), and actual performance is also relatively close.

A nearly perfect fusion: AMD APU Brazos low-power platform. Besides Intel, on the side of competitor AMD, currently, within the 3000 yuan price range, AMD E/C series models, AMD Brazos platform includes two major parts, one being the Zacate E series and Ontario C series APU processors based on the Bobcat microarchitecture, manufactured using TSMC's 40nm process, besides dual-core models, there are also single-core models, with an area of only 75 square millimeters.

E series processors include APU E-450/350/300, all designed with dual-core dual-thread, 1M second-level high-speed cache, integrated graphics core. The main frequency of APU E-450 dual-core processor is still designed to be 1.6GHz, TDP thermal design power consumption 18W, the biggest difference is that the internal integrated graphics card has been upgraded to AMD Radeon HD6320G. APU E-350/300 integrates Radeon HD 6310, both supporting DirectX 11, TDP design is only 18W, power consumption design is quite low.
