For dual-core high-definition laptops under 3K, recommendations show that low-end products do indeed have a market. When "tall, rich, and handsome" becomes a new term for those with gold-and-diamond-encrusted Macbook Air SUPREMEFIRE, extremely high-end Dell Alienware extraterrestrial maniacs, and other high-end, luxurious configurations shine brightly, hiding beneath them are budget-friendly models under 3K yuan, such as Pentium B9 series, Celeron B8 series, Core i3 series with HD 3000 integrated graphics, and AMD E/C series machines. These low-end products buried in the corner of the market are not eye-catching and even dim.
Targeting entry-level users, this article first compares the configuration and performance differences of low-end products under 3K yuan, then recommends and introduces integrated graphics and discrete graphics products at lower prices for daily internet entertainment users and wage earners who prioritize low price and practicality.
Test results of Celeron B815 integrated graphics based on Sandy Bridge architecture
Similar to the positioning of netbooks, Brazos APU's low-power design, especially designed for high-definition video books, online entertainment, and portable devices, is clearly not aimed at 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 really too weak. However, under the premise of only 18W power consumption (including GPU), the E/C series processors of Brazos APU can perfectly realize high-definition videos and surpass Atom and ION combinations in all aspects. Undoubtedly, the Radeon HD 6320/6310 graphics core paired with the 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, faster than most current integrated graphics cards, and even comparable to Sandy Bridge architecture's HD Graphics 3000 under DirectX 11 features. Isn't this enough?
AMD APU E-450 (integrated graphics): 1024x768 (left), 1280x768 (right)
Thus, in the market, the performance under 3K yuan can be divided as follows when purely discussing integrated graphics: Core i3 integrated graphics > Pentium B9 series integrated graphics > Celeron B815 integrated graphics > APU E-450. Due to the low-power design of the Brazos APU series processors, from the 3DMark06 test results, it almost equals the test performance of Celeron B815, with little difference between the two. Although the main frequency of the APU E/C series is relatively low, adding a discrete graphics card configuration can greatly reduce the data pressure on the CPU's graphics performance.
On the other hand, within the 3K yuan price range, selecting integrated graphics models is more balanced. However, in addition to many integrated graphics models, various laptop manufacturers also offer many discrete graphics models to enhance performance, such as Pentium B9 series paired with GT 540M, HD 6370M, APU E-450/E-350 paired with HD 6470M discrete graphics cards, etc., and the performance improvement is quite significant. Below is the product configuration and price table introduced in this article for five products under 3K yuan.
Through 3Dmark06 performance testing of Celeron Dual-Core B815, since the test includes the comprehensive performance of both the graphics card and processor, it can also be used 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. This Celeron Dual-Core B815 scores 2911 points, making the distinction very clear. 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 may notice 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 AVX instruction set support and reduced third-level cache. Compared to its "hardship brothers" Pentium Dual-Core B9 series, many specifications are very similar, such as both having 2MB third-level 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 near-perfect fusion: AMD APU Brazos low-power platform
In addition to Intel, on the AMD side, currently within the 3K yuan price range, AMD E/C series models, the AMD Brazos platform includes two major parts: Zacate E series and Ontario C series APU processors based on the Bobcat microarchitecture, manufactured using TSMC's 40nm process, with areas of only 75 square millimeters. There are both dual-core and single-core models in the E series processors.
E series processors include APU E-450/350/300, all designed with dual-core dual-thread, 1M second-level high-speed cache, and integrated graphics core. The APU E-450 dual-core processor has a clock speed still designed at 1.6GHz, TDP thermal design power consumption of 18W, with the biggest difference being the internal fusion of the AMD Radeon HD6320G graphics card. The APU E-350/300 integrates Radeon HD 6310, supporting DirectX 11, with a TDP design of only 18W, indicating very low power consumption.
