Later this year, or even in the current quarter, AMD plans to start shipping the first processor for Socket AM4. Bristol Ridge line of performance-oriented segment, and the first tests appeared in Korea. Tested high-end model with four core A12-9800 on 3.8-4.2 GHz with integrated graphic core Radeon R7 8 CU at a frequency of 1.108 MHz. The processor supports DDR4-2400 memory and consumes up to 65 watts.
A12-9800 processor compared with A10-7870K of Kaveri family. High-end of the previous generation model is based on four core CPU with a frequency of 3.9 to 4.1 and GPU with eight CU at frequency up to 866 MHz. But TDP predecessor was 95 watts. In addition to better performance, the family of Bristol Ridge also works more efficiently. Both processors were tested on the platforms and AM4 AM3 +, DDR3 and DDR4 memory, and chipsets A88 or B350M.
In A12-9800 tests on computer performance showed a 5% increase, according to media – by 13%. DDR4 memory throughput capacity increased by 20%. In tests, 3DMark and PCMark 8 with the video card GeForce GTX 1070 Founders Edition, when performance is measured only cores, an increase of 10-15%.
Four core A12-9800 showed growth of 6% in single-threaded tests, in multithreaded advantage was 15%. SATA Express and SATA3 support platform AM4 has led to the increase in capacity connected SSD and hard drives up to 50%. Integrated graphics core also got a significant performance increase up to 20%.
Productivity gains in the tests was accompanied by a decrease in energy consumption. In tests Kaveri A10-7870K power consumption by up to 78 W, in the case of Bristol Ridge A12-9800 it did not rise above 57 watts. That is, we got energy savings up to 27%.
There were even made overclocking attempts. It was possible to increase the clock speed from 4.2 GHz to 4.8 GHz. To disperse the used motherboard ASUS Octopus B350M on the chipset. For cooling the processor was used the cooler from AMD Wraith with a maximum heat up to 95 watts. With cooling water or liquid dispersal can expect better results.
