How about amd a8 processor 'Detailed introduction: AMD A8-7680 processor review'

php Editor Apple brings you a detailed introduction and review of the AMD A8-7680 processor. As a mid-range processor, the AMD A8-7680 performs well in terms of performance. It uses the innovative Bristol Ridge architecture with four cores and eight threads, capable of handling multitasking and multithreaded work. At the same time, it is also equipped with a powerful integrated graphics card that supports high-definition video playback and light gaming. Taken together, the AMD A8-7680 processor is a cost-effective choice, suitable for general office and entertainment use.

1. Foreword: You read that right! The ancient FM2 platform has welcomed a new member

In October 2018, AMD released an A8-7680 APU processor belonging to the Carrizo family. This processor uses the sixth-generation excavator architecture APU, and the processor interface is FM2 instead of the latest AM4.

The author was surprised when I just received this processor. I didn’t expect that AMD could still launch such a previous-generation APU two years after the launch of the Ryzen processor.

However, after calming down and analyzing, A8-7680 actually has a certain significance.

FM2 platform supports AMD's special DDR3 memory modules, whose performance is equivalent to ordinary DDR3 memory, but the price is less than half. Therefore, users who do not have high performance requirements can choose the A8-7680 to build an entry-level platform with the ultimate cost-effectiveness.

Second, below Athlon 200GE, we need an entry-level platform for office and ordinary home use. However, INTEL low-end processors are seriously out of stock, and they are all second-hand products, especially second-hand motherboards. There are certain hidden dangers and there is no warranty.

Third, A8-7680 is a quad-core product. It consists of four integer cores plus 2 floating-point cores. It may be slightly inferior to G4560 in terms of floating-point performance, but its integer performance is far stronger. to the opponent. Our daily operations such as web browsing, web video, office work, etc. basically use integer performance.

In addition, it still supports the Windows 7 platform, which is still a strong need for many users. Nowadays, many users are accustomed to Win7, but are forced to use Win10.

For the above considerations, AMD has launched such an FM2 platform A8-7680 processor.

The A8-7680 processor still uses 28nm Technology process, four-core four-thread design, base frequency 3.5GHz, maximum frequency 3.8GHz, the highest measured full-core frequency is 3.7GHz, 320KB first-level cache, 2MB second-level cache.

The CPU core architecture is the ultimate version of the bulldozer family, the Excavator, which was not available on the FM2 platform in the past.

In terms of GPU, it integrates Radeon R7 graphics processor, with 384 stream processors, a maximum frequency of 900MHz, 8 raster units (ROP) and 24 texture units (TMU).

Another point is that the TDP advertised when the A8-7680 was released was 45W, but when we checked it with CPU-Z and other software, the TDP displayed was 65W, which should be because the support is not yet in place.

The recommended retail price of this processor is 399 yuan, but it can actually be purchased on e-commerce platforms for less than 300 yuan. There are also board U sets, priced between 499 and 699 yuan.

One thing that needs special attention is that if users purchase the processor and motherboard separately, they need to upgrade the BIOS of the FM2 motherboard to the latest version first, otherwise they will not be able to light up.

2. Appearance: The highlight is that it can support AMD’s special DDR3 memory sticks

The front faces of AMD processing are similar, and generally only the text labels are different. Too same.

Installed on the motherboard.

GIGABYTE F2-A68HM-S1 motherboard supports FM2/FM2 pin APU processor and adopts 5-phase power supply circuit design.

In terms of expansion slots, there is a full-speed PCI-E x16, a PCI-E x4 and a PCI slot. There are also 4 SATA3.0 interfaces.

2 DDR3 memory slots, supporting up to DDR3-2133MHz frequency memory. It also supports AMD’s dedicated DDR3 memory, which is half the price of ordinary DDR3 with the same capacity.

The video interface on the back of this motherboard only has one VGA. If your monitor supports it, there will be no problem. If the monitor does not have a VGA interface, you can choose Purchase other motherboards with DVI and HDMI outputs.

3. Performance test: Game performance is 2 times that of G4560 and office performance is also not weak

The test platform is as follows:

The comparison between the two test platform configurations is not very fair, because we only have two Kingston DDR3 1333MHz 4GB on hand. During the test, we overclocked them to 1600MHz, and the G4560 platform used the Zhiqiang Light Halberd, and turned on XMP during the test. Run directly at 3200MHz.

In addition, since the A8-7680 platform does not support M.2, the main hard drive on AMD's side can only use Plextor PX-256M6Pro with SATA interface, and on Intel's side it is Samsung 960 Pro 512GB.

1. APU game performance test

3DMark

##The built-in core graphics score of A8-7680 is 697, honestly This score is a bit lower than expected, mainly due to insufficient DDR3 bandwidth and too few raster units (ROP) for the core display.

Nevertheless, in the 3DMark Fire Strike Extreme test, the A8-7680 performed 2 times better than the G4560.

Overwatch

"Overwatch" is Blizzard Entertainment's first entry into the FPS field. It became popular all over the world in 2016, and its influence once exceeded LOL. Even now, there are still a considerable number of them. of players are active in the game.

"Overwatch" has relatively high requirements on graphics cards. We tested the game frames at 75% and 100% rendering under 1920*1080 high special effects.

In "Overwatch", whether it is 75% rendering or 100%, the G4560 has only a dozen frames, completely losing its playability. The A8-7680 has 24 frames at 100% rendering, which is barely playable. It can reach 35 frames at 75% rendering. It can perform various complex movements and operations relatively smoothly. If the special effects or resolution are appropriately reduced, it can be further improved. Improve fluency.

League of Legends

As the competitive game with the largest number of players at present, the emergence of "League of Legends" has greatly promoted the development of global e-sports. A large number of events are held around the world every year . We conducted the test at a very high image quality of 1920*1080. For the sake of fairness, we chose the birthplace of the game as the test scene.

G4560 had a frame rate of 38 in the birthplace of the game at the beginning, but in the later stages of the melee, the frame rate dropped to about 20 frames. The A8-7680 measured 80 frames and was able to maintain over 50 frames even during team battles.

Master Lu

Because the program itself is not rigorous enough, Master Lu will generally not be used as an evaluation item, but its scores still have certain reference significance.

##The above picture is the A8-7680, and the following is the running score of the G4560. In terms of processor performance, the A8- The 7680 scored 33556 points, 4000 points behind the G4560; but in terms of graphics performance, the A8-7680 scored 24814 points, almost three times that of the G4560.

2. CPU theoretical performance test

The results of A8-7680 running CPU-Z are not high, single-threaded 239 points, multi-threaded 785 points.

Compared with the G4560, the A8-7680 is 121 points behind in single-threading and 241 points in multi-threading.

wPrime v2.10

A8-7680 took 39.5 seconds to run 32M in single thread, and 340 seconds to run 1024M in multi-thread. .

The A8-7680 multi-threaded running of 1024M took 105 seconds less than the G4560, leading the opponent by 30%.

X264 FHD Benchmark

For students who have video suppression and transcoding needs, the performance of these three processors is basically the same. The A8-7680's score in the X264 FHD Benchmark is 12.6fps, which is only 0.2 frames less than the G4560.

Let us use PCMark 10 to test the office performance of the processor.

In the PCMark 10 Work test, the A8-7680 is more than 20% stronger than the G4560.

4. Power consumption and temperature test: The power consumption of the baking machine is a pain point. The maximum temperature of the baking machine is 47 degrees. In terms of power consumption, the 28nm A8-7680 should be at a disadvantage against the 14nm G4560.

The room temperature was 18 degrees during the test, and both platforms used their own original radiators.

1. Power consumption test

Test the power consumption of standby, oven, and 3DMark respectively. The oven test is to read the power consumption of the platform after running the latest version of AIDA64 FPU for about 20 minutes.

In standby mode, because the AMD platform uses lower DDR3 frequency and the Intel platform lacks 3200MHz DDR4, the A8-7680 seems to have even lower power consumption. On 3W.

During the oven test, the power consumption of the A8-7680 platform was much higher than that of the G4560. In addition to the reasons for the process technology, the G4560 processor castrated the AVX instruction set, which also caused the power consumption of the oven. Very low reason.

When running 3Dmark, because the G4560 core display is too weak, the usage of the CPU itself is not high, so the power consumption of the whole machine is now 42W. The power consumption of the A8-7680 reaches 69W, but considering that its 3D performance is much stronger than that of the G4560, this power consumption is considered reasonable.

2. Temperature test

Test the standby and oven temperatures respectively. G4560 uses the boxed radiator, while for A8-7680 we got loose chips, so we use Athlon The radiator that comes with 200GE was tested. The room temperature during the test was 17 degrees.

After running the AIDA64 FPU for 7 minutes, the temperature of the A8-7680 stabilized at 47 degrees.

The standby temperatures are similar, but the power consumption of the A8-7680 roaster is higher, so the temperature of the roaster also reaches 47 degrees, which is 9 higher than that of the G4560 Spend.

5. Summary: 1,000 yuan to build an entry-level platform with the ultimate cost-effectiveness

Generally speaking, the A8-7680 processor competes with the G4560 in terms of CPU performance, especially in office performance. Completely defeat the opponent. In terms of graphics performance, it can reach more than 2 times that of competitors. For games such as LOL, CS:GO, and DOTA2, the A8-7680 can play smoothly at the highest resolution of 1080, with reduced special effects, such as " Games like "Overwatch" can also achieve playable frame rates, but the Pentium G4560 has almost no game-playing characteristics due to its poor core graphics.

The biggest disadvantage of the A8-7680 is power consumption. After all, the 14nm G4560 is packed lightly, while the A8-7680 has four physical cores, an AVX instruction set and a GPU with 384 stream processors, which are quite energy-consuming. electricity. Even so, its standby power consumption of 26W and oven power consumption of 91W are within acceptable ranges.

In fact, AMD’s biggest intention in launching the A8-7680 is to allow users to build an entry-level host with the highest cost performance.

Since A68HM can use low-priced AMD dedicated DDR3 memory sticks, it only costs 1,000 yuan to build an A8-7680 processor host platform.

For entry-level platforms, whether the memory is DDR4 or DDR3 does not have much impact. Intel can only use DDR4 memory, so it will cost 1,600 yuan to build an entry-level platform with a G4560 processor. .

What's more, A8-7680 can install the Windows 7 platform that many people can't leave until now, without having to use the latest and more criticized Windows 10. This is also very attractive.

As a gamer, I definitely don’t like this kind of entry-level platform, but if it is just used as an office machine or an audio-visual entertainment machine used by parents and elders, the performance of the A8-7680 is sufficient, and It can save 40% on the budget compared to the same Intel platform, not to mention it has certain gaming capabilities!
