AMD's new flagship A12-9800 review: finally using DDR4 memory
|
Intel has started pre-selling the seventh-generation Core KabyLake, while AMD has released the seventh-generation APU Bristol Ridge. As early as the beginning of this month, AMD quietly released a new generation of APUs, but it seems that it has not been released in China. There is no trace of the new APU. It is estimated that the old stock has not been cleared out. In addition, AMD intends to promote it only in OEMs, and the DIY market may not be able to get it. Despite this, we can still find relevant reviews of the new APU from foreign review websites. Don't worry about how the APU has reached the seventh generation. This generation of APU is codenamed Bristol Ridge, using the new AM4 interface. It needs to be paired with a new chipset motherboard to support DDR4 memory, USB 3.1, etc. However, compared with the current desktop version of Godavari or Kaveri APU, the new APU has an upgraded CPU architecture from a pile driver to an excavator, and a GPU from GCN 1.1 to GCN 1.2, and then... It is not much different from the Carrizo APU (mobile version) released last year. Now it is just a supplement to Carrizo without a desktop version. The left side is the FM2 interface, and the right side is the AM4 interface. The number of pins in the new interface has increased significantly, up to 1331. The seventh generation APU includes a total of 8 models. In addition to the newly added A12, there are also the familiar A10, A8, A6 and Athlon x4 without GPU, with two TDPs of 65W and 35W. Among them, the first high-end model is A12-9800, with four cores at 3.8-4.2GHz, Radeon R7 GPU 512 stream processors, and supports up to DDR4-2400. The thermal design power consumption is 65W. Unfortunately, the process continues to stagnate. However, AMD still claims that it can compete with Intel Core i5-6500. Attached below is a comparison test of the new flagship APU A12-9800 and the flagship A10-7870K, which is code-named Godavari (Kaveri's vest) reprinted from South Korea. CPU performance test: The single-core performance of A12-9800 is improved by about 6% and the multi-core performance is improved by 15% compared with A10-7870K. Nuclear graphics performance test: In terms of nuclear graphics, the new APU A12-9800 Fire Strike ran 1880, which is nearly 400 points higher than A10-7870K. There is also a small improvement in rendering. With the GTX 1070 independent graphics card running 3DMark and PCMark, the two have opened up a gap in the Fire Strike project. Storage performance test: The more obvious changes are also in the storage aspect, with up to 20% bandwidth improvement. Although the motherboards with the future mainstream B350 chipset have good improvements, the continuous read and write performance of the SATA port provided by the APU is better than that provided by the B350 motherboard, but the random performance is weaker than the SATA port of the B350. Plug in the GTX1070 independent graphics card to play games: In the game test, "Tomb Raider 10", with the GTX 1070 graphics card, the performance has increased by 10~15%. Power consumption and temperature performance In terms of power consumption, the TDP gap itself is obvious, and the actual measurement is consistent. In the Prime95 temperature test, it is 20 degrees lower than the A10-7870K. In conclusion: After reading this review, I believe everyone has the same feeling. Although the new APU A12-9800 has good optimizations in performance and power consumption, given that the current market demand for APUs is relatively saturated and there is a backlog of old products, it would be a shame to hastily promote it in the DIY market and update it too frequently, which would put pressure on AMD's survival and prevent them from recovering their funds... Promoting it only in OEMs is not a bad thing, after all, the protagonists are Zen and its APU... The seventh-generation APU is more of a role in helping to promote the new motherboard before Zen arrives.As a winner of Toutiao's Qingyun Plan and Baijiahao's Bai+ Plan, the 2019 Baidu Digital Author of the Year, the Baijiahao's Most Popular Author in the Technology Field, the 2019 Sogou Technology and Culture Author, and the 2021 Baijiahao Quarterly Influential Creator, he has won many awards, including the 2013 Sohu Best Industry Media Person, the 2015 China New Media Entrepreneurship Competition Beijing Third Place, the 2015 Guangmang Experience Award, the 2015 China New Media Entrepreneurship Competition Finals Third Place, and the 2018 Baidu Dynamic Annual Powerful Celebrity. |
