Who says there's no market at the low end? When "Tall, Rich, and Handsome" becomes a new term, those Macbook Airs adorned with gold and diamonds, SUPREMEFIRE, extremely high-end Dell Alienware extraterrestrial maniacs, all sorts of high-end, luxurious configurations shining under the halo, hide beneath the plain appearance within the 3000 yuan price range—Pentium B9 core, Celeron B8 core, Core i3 core HD 3000 integrated graphics, AMD E/C series models deeply buried in the market corner, these low-end products are so unobtrusive and even dim. For entry-level users, especially daily online entertainment users and working-class people seeking cost-effective options, this article first compares the configuration and performance differences of low-end products below 3000 yuan, then recommends and introduces integrated and discrete graphics products at lower prices.
Testing the integrated graphics of Sandy Bridge architecture Celeron B815. Just like the positioning of netbooks, Brazos APU's low-power design is specifically aimed at high-definition video books, online entertainment, and portable devices, clearly not mainstream performance. Although Brazos APU was born at an inopportune time during the decline of netbooks, in terms of data processing performance, compared to A-series APUs, Brazos APU is indeed too weak. However, under the premise of 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 is a perfect combination. It can basically handle mainstream high-definition videos, online entertainment, and even some 3D games at the entry level settings. The speed is also faster than most integrated graphics cards currently available, and it does not fall short of 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 segmentation, the performance below 3000 yuan can be divided as follows when purely discussing integrated graphics: Core i3 integrated graphics > Pentium B9 core integrated graphics > Celeron B815 integrated graphics > APU E-450. Since the Brazos APU series processors are designed for low power consumption, from the 3DMark06 test results, they almost match the performance of Celeron B815, with little difference between the two. Although the main frequency of APU E/C series is relatively low, 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. In addition to many integrated graphics models, notebook manufacturers also offer numerous 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 and price table of five products within 3000 yuan introduced in this article.
Through 3Dmark06 testing the performance of Celeron Dual-Core B815, since the test includes the comprehensive performance of both 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 approximately 3600 points, while Pentium Dual-Core B940 + HD3000 integrated graphics scores around 3100 points, and this Celeron Dual-Core B815 scores 2911 points, showing a clear distinction in performance levels. Under the Sandy Bridge architecture, performance ratios can be roughly calculated as follows: Celeron B815 = 80% x Pentium B940 = 72% x Core i3 (integrated graphics).
Careful friends will notice that since the Celeron B815 dual-core processor continues the Sandy Bridge architecture, its disadvantages compared to Core i processors include not supporting AVX instruction sets and having the L3 cache cut down. Compared to the "hard-luck brothers" Pentium Dual-Core B9, many specifications are very similar, such as both having 2MB L3 cache, GPU graphics core frequency of 650-1050 MHz (Pentium B9 GPU dynamic frequency is 650-1100 MHz, slightly higher), and actual performance is also quite close.
A nearly perfect fusion: AMD APU Brazos Low-Power Platform
Besides Intel, on the AMD side, the current configurations within the 3000 yuan price range include AMD E/C series models. The AMD Brazos platform consists of two major parts: one is the Zacate E series and Ontario C series APUs based on the Bobcat microarchitecture, manufactured using TSMC's 40nm process. Besides dual-core models, there are also single-core versions, with an area of only 75 square millimeters.
The E series processors include APU E-450/350/300, all designed with dual-core dual-threading, 1M Level 2 high-speed cache, and integrated graphics core. The dual-core APU E-450 processor still has a clock speed of 1.6GHz, TDP thermal design power consumption of 18W, and the biggest difference is that the internal integrated graphics card has been upgraded to AMD Radeon HD6320G. The APU E-350/300 integrates Radeon HD 6310, supports DirectX 11, and the TDP design is only 18W, making the power consumption design quite low.
