1920 X 1080 => 270.63 FPS

Above is the performance of three kinds of 3D software under 4.7GHz, which is also affected by the CPU performance.

Regarding the 3D scores, it is 10% less than that of 2500K OC 5GHz. It needs to be further improved in the future AMD architecture.

990FX provides the bandwidth of ATI CrossFireX X16+X16, which can get better performance than the dual-VGA of the same specification.

External frequency of FX-8120 also gets good performance. If you want to increase the DDR3 performance more, the most direct way is to increase the CPU external frequency.

In this way, it can probably reach the level of DDR3 2000~2200.

CPU 262 X 18 => 4716MHz

ADIA64 Memory Read - 14914 MB/s

Sandra Memory Bandwidth - 19369MB/s

MaXXMEM Memory-Copy - 15013MB/s

The external frequency of FX-8120 can be stable around 255MHz. CPU external frequency within the overclocking range also performs well.

After increasing DDR3, it can almost reach 15000 MB/s in AIDA64 Memory Read.

Compared with the previous AMD platforms, the bandwidth performance when overclocking is increased by about 40~50%, which is also one of the greatest feature for this new platform.

Reaching 5GHz

Super PI 32M X 1 => 16m 49.743s

CPUMARK 99 => 554

5GHz is not easy to reach for FX-8120, even if the heat dissipation system is enhanced.

The key is whether the physical quality of the CPU is excellent or not. Generally, it can reach almost 4.8~4.9GHz, thereby making operating system (0S) run smoothly.

Although reaching 5GHz in OS, it can’t be stabilized, which can be only reached under single PI and 32M.

If it requires running 8 PIs simultaneously, it can’t be reached even if it is 1M.

That’s why the overclocking should consider whether each core of the multiple cores has the same excellent physical quality.

BIOSTAR TA990FXE uses the AMD’s most advanced 990FX integrated with SB950 chipset.

The price in U.S. is about US$115(no more than NT$3,500), which is affordable to most people.

The performance is also one of the major features of BIOSTAR, which gets good performance in the test after overclocking.

Moreover, 990FX has the advantage of dual-X16 and built-in native SATA3 and USB 3.0, which is quite advanced in the hardware specification.

BIOSTAR TA990FXE

Advantages

1. The package and materials are both above the level, and the price is still fair among 990FX series.

2. Its BIOS has been integrated with UEFI interfaces, with rich options, and a large voltage range as well as excellent overclocking capability.

In AMD’s Bulldozer platform, we can see the improvement brought by the new architecture, and the shortcomings as well.

The advantage is that AMD integrates new 32nm process, and launches the 8-Cores design in the common PC consumption market for the first time.

When FX-8120 is not in the overclcoking state, the power consumption and temperature both get good performance.

The overclocking degree also pushes the AMD CPU and DDR3 clock to higher field, and the DDR3 performance is improved greatly as well.

The shortcoming is the price which made AMD proud all the time. This time FX-8120/8150 will make the consumer feel some kind of expensive.

The single-core performance is a little bit lower than that of 1090T, so are the multi-task performances of some software.

When overclocking FX-8120 to 4.3GHz or higher, the temperature and power consumption amount will increase a lot.

These three aspects should be strengthened by AMD to increase the efficiency under multi-task environment through architecture optimization, BIOS modification or software support.

I think many AMD fans have been waiting for Bulldozer architecture for more than one year,

who can only know the 8-core performance from the hearsay news on the Internet or the test information revealed by media abroad during this period.

In this article, windwithme spent nearly two weeks to make calibration for overclocking.

Initially, I hoped it could reach the level of stable burning by 4.6GHz or higher to present the best performance of FX-8120. However, it didn’t make it, which is pitiful.

Bulldozer brings about surprises and some disappointment. Personally, I think the disappointment is more than surprises.

When writing this article, I got some complicated feelings. Maybe it is because I still have the passion of pursuing K7 high C/P and K8 high-performance CPU.

When can we see the unsurpassed magnificence of AMD when the performance of K8 Athlon 64 3000+/3200+ was overwhelming on the market again?

When will AMD make us crazy about it again, and make some new-era architecture that is really perfect in overall aspects?

I still hope AMD can perform better in the medium- and high-order market in the future, and have the glorious period as before.

I believe that it is also the expectation of many consumers...

CINEBENCH R11.5

CPU => 7.62 pts

CPU(Single Core) => 1.15 pts

PCMark Vantage => 16970

PCMark7 => 4432

Windows experience index - CPU 7.8

After overclcoking FX-8120 to 4.7GHz, the performance of CINEBENCH is increased by about 20% in single core, and over 50% in 8-core at full speed.

Besides, MP Ratio is also increased to 6.63x, which should be an important factor to cause the significant improvement of the multi-core performance.

The performance of other software in the entire platform is significantly improved as well.

It seems that the performance of FX-8120 after overclocking is comparatively outstanding.

However, the Windows experience index is still 7.8 scores. The simple test software built in Windows7 is necessarily enhanced in the accuracy aspect.

DDR3 1866.6 CL8 10-9-24 1T

ADIA64 Memory Read - 14194 MB/s

Sandra Memory Bandwidth - 18627 MB/s

MaXXMEM Memory-Copy - 13985MB/s

FM1 APU released by AMD in July, if without overclocking, can be maximized to DDR3 1866.

The architecture of AM3+ Bulldozer this time has the same specification. It is unlike the previous platforms that can only support DDR3 1600 at most.

The improvement in frequency is also the feature of this new platform, and the bandwidth is slightly increased after it is adjusted to DDR3 1866.

Power consumption test

System standby - 79W

CPU at full speed - 401W

CPU test items in CINEBENCH R11.5 running

For the power consumption duing system standby, it just increases 5W once overclocking.

It may be resulted from enabling C&Q power-saving technology. This part is fairly good.

However, the power consumption amount after overclocking increases a lot.

When I tried 4.3GHz by using LinX burning, the power consumption reached around 380W.

It couldn’t conduct burning by using LinX under 4.7GHz. When I tested the 8-core capabilities by CINEBENCH R11.5, it still got the data of 401W.

The power consumption of FX-8120 after overclocking is quite high, which is one of the factors in need of improvement in the future.

I don’t share more about the temperature test after overclocking.

The first reason is that LinX can be only running under 4.3~4.5GHz.

After replacing it with Thermaltake advanced air cooler or CORSAIR H80 to enhance the heat dissipation capabilities, the overclocking stability couldn’t be improved as well.

Another reason is that displayed temperature is only around 42~46 Celsius, which should not be the actual temperature.

When I disassembled the tower air cooler after burning at 4.3GHz, the heat dissipated from the heat sink shocked me a lot.

The power consumption of FX-8120 obtains rather good performance under default configuration.

The power consumption difference between standby and full speed is 83W.

The integration of 32nm process is greatly helpful to the CPU of AMD’s new-era FM1 or AM3+ architecture.

Below will share the overclocking of FX-8120

BIOSTAR has integrated new UEFI graphic interfaces in 990FX BIOS.

Some power-saving functionality in the CPU information page can make some further adjustment.

O.N.E calibration page

Voltage page

CPU Vcore +0.050~1.450V

CPU-NB Over Voltage +0.050~0.200V

Memory Over Voltage -0.250~+0.490V

NB Over Voltage +0.010~0.490V

CPU HT Over Voltage +0.010~0.300V

SB Over Voltage +0.010~0.300V

NB HT Over Voltage +0.010~0.300V

CPU frequency multiplication can be adjusted here too. To increase the external frequency, it needs to lower NB FID first.

If you want to reduce CPU voltage, you can also start from the option of Core VID

As for the DRAM frequency and parameter settings, generally, smaller the values are, higher the performance is.

Different from the previous platforms, FX-8120 supports DDR3 1866 for the first time.

In the past, the maximum CPU of the version inferior to 1100T can be only adjusted as 1600.

Below it is set as DDR3 1866 CL8 10-9-27 1T

PC Health Status

CPU temperature detection data is higher than some software in OS, so this comparison is much closer to the actual temperature performance.

Above are the set values by windwithme to overclock FX-8120 to 4.7GHz and integrate with DDR3 1866.

The overclocking settings are easier than that of frequency-unlocked FX CPU. It just needs to adjust CPU frequency multiplication, and then adjust the CPU voltage to the acceptable value.

In comparison, the overclocking of DDR3 is also in the similar way, which requires adjusting DDR3 1600/1866 first, and then setting parameters or increasing DDR3 voltage.

If the operation voltage can be stabilized after overclocking CPU/DDR3, it means that the overclocking is successful.

Windows experience index - CPU 7.8

The single-core performance of FX-8120 presented in CINEBENCH R11.5 is almost the same as that of A8-3850 or Athlon II X4640,

and 10% lower than that of Phenom II X6 1090T. So the FX series needs enhancement in single-core performance.

Multi-task is still the major feature of FX-8120. The software of CINEBENCH can get score of about 5.04 under 8-core at full speed.

However, by taking a close look, we can see that it only gets 5.31x for MP Ratio. Compared with 3.89x of X4 640 and 5.22x of x6,

the best multi-task performance can only reach the level of the last-generation X6.

It may be correlated to the design of new architecture, or the performance will be enhanced by Windows 8 as mentioned on the Internet.

As for the best Windows experience index of above software, FX-8120 can get the high score of 7.8 under default configuration.

DDR3 1600 CL7 9-8-24 1T

ADIA64 Memory Read - 13516 MB/s

Sandra Memory Bandwidth - 16554 MB/s

MaXXMEM Memory-Copy - 12839 MB/s

DDR3 performance is obviously improved in AM3+ CPU. Compared with 1090T under DDR3 1600, it is improved by over 30%.

It should be the best improvement among FX series. It has gone through three generation of DDR~DDR3, from K8 DDR to the latest 1090T DDR3.

Regarding the DRAM bandwidth, the maximum Read keeps around 10000 MB/s. Over the past eight years, the AMD bandwidth has been increased finally.

Although a small step in PC market, it is a big one for AMD. It is hoped to catch up with the competitor’s platforms in DDR3 performance in the future.

Temperature performance (Ambient temperature is 22 Celsius)

System standby - 13~27

CPU at full speed - 22~33

LinX 0.6.4

In comparison with the temperature by touching the water cooled radiator, the burning temperature of FX-8120 under default frequency is lower than that of 1100T, so the temperature improvement is great.

It can be seen from the shared test of 32nm A8-3850 that the CPU temperature is always low according to much software.

It remains the same after I use A75 of more than three brands. However, the temperature is not so low when I touch the heat sink, which is about 50 Celsius according to my analysis.

The abnormal CPU temperature is also shown on FX-8120. As mentioned by some media abroad, it might be caused by the inaccurate temperature information provided by FX CPU to MB.

The above temperature data detected by various software is just for reference, but without representing the actual temperature of FX-8120 capably.

TA990FXE adopts 4+2 phase power supply. The upper left is 8Pin power input.

It adopts the black AM3+ slot exclusively for AMD’s advanced MB.

View of the heat dissipation module on the heat pipe

It is not bad in the texture and the contact area, and the red aluminum sheet makes it look more beautiful.

The heat sink of North Bridge 990FX has large area for Aluminum extruded heat dissipation.

Its shape is also designed for the consideration of preventing the large VGA from being stuck

The heat sink of South Bridge SB950 is a little thin. If it is designed as North Bridge, they will be consistent in the view and texture.

Test platform

CPU: AMD FX-8120 8-Core Processor

MB: BIOSTAR TA990FXE EXTREME EDITION

DRAM: CORSAIR CMZ8GX3M2A1866C9R

Cooler: CORSAIR Hydro Series H60

OS: Windows7 Ultimate 64bit SP1

There are more and more enclosed water cooled products in the market within the last two years,

which have advantages of unnecessary replacement of coolant booster, convenient installation and good performance.

Even the AMD’s most advanced FX-8150 is integrated with solution of the water cooled heat sink.

Moreover, Intel has also started to buy water cooler heat sink since the series of Sandy Bridge-E.

The heat sink used in this test is CORSAIR water cooled module, with the module number as Hydro Series H60 that is featured by silence.

Below is the external package of H60. The warranty period is as long as five years, and the package size is much smaller than that of H80.

The attached accessories

The bottom is the installation manual and introduction of other product information.

The upper left side is a 12*12*2.5 cm fan, with the maximum rotation speed as 1700 RPM, fan flow as 74.4 CFM, sound volume as 30.2 dBA.

The upper right side is the buckles and installation screws for each platform. H60 supports the platforms of AMD AM2/AM3. Intel LGA 775/1155/1156/1366.

The left side is the entirely-black water cooled radiator, dimension of 120mm*152mm*27mm

H80 water cooled radiator is 38mm thick, while H60 is 27mm thick, whose dimension is different from these two.

The right side is the water block. There is a clear brand logo on the upper side. This picture is the view installed with Intel Buckles.

It can be seen from the rear side that the bottom of the water block is copper.

The stacked fin sheets in the middle of the water cooled radiator provide larger heat dissipation area.

This platform is mainly integrated with the built-in GPU in CPU by AMD for the first time, and the 3D performance thereof is greatly improved than before.

Regrettably, FM1 is incompatible with AM3+ pin under its own brand. I have already shared three articles about the test of FM1 platform.

FM1 mentioned above belongs to the product line of the medium-level or entry-level platform,

while Bulldozer is the new platform advanced than medium-level of AMD, which is a hot term on the Internet.

By following the design of the previous platforms, Bulldozer’s architecture adopts AM3+ pin.

CPU has three categories of 4-Cores FX-4100?6-Cores FX-6100 and 8-Cores FX-8120/FX-8150,

among which the two 8-Core categories are the most eye-catching. After all, they are the first products shown in the Desktop PC market.

After several delays, AMD Bulldozer is finally issued in the mid of October and has been sold on the market successively.

There is a lot of related information on the Internet and graphic magazines.

This time I bought an AMD FX-8120 Processor with 8-Cores, 32nm process and TDP of 95W.

The core name is Bulldozer, the clock is 3.2GHz and the specification from Turbo Core to 4.0GHz, L2 8MB and L3 8MB is supported.

The upper left is FM1 A8-3850, lower right is AM3+ FX-8120. The front side comparison between the CPUs of these two architectures

The rear side comparison

The left is FM1, and the right is AM3+. It can be obviously seen that the CPU pins of these two are incompatible.

Recently, some cyber friends mention that I shared little information about the CPU. Personally, I think CPU can be only described by specification and appearance photography.

As for other CPU information, it can be told from the software test below, which is the major part of this article.

Through the pictures of practical test, the CPU performance can be fully presented.

Therefore, this time I add the comparison of the two sides between the CPUs of these two AMD pins, thereby hopefully sharing more details about the CPU-related information.

Regarding the chipset, AMD provides the combination with the three types of 970, 990X and 990FX. 990FX was successively on shipment by major MB manufacturers in August.

FX-series CPU was however released in the mid of October, about over two months later. It is rare in the past PC market.

MB uses BIOSTAR TA990FXE, which is in red package, and belongs to the EXTREME EDITION version under its own brand.

Whole view of BIOSTAR TA990FXE

AMD adopts the dual-bridge chipset design as before instead of single chipset, combining the North bridge 990FX with the South bridge SB950.

This combination is the most advanced chipset of AMD, and most MB brands only release the ATX specification.

As for the color, it still uses black PCB, and other slots such as PCI-E or DIMM use red or white.

The advantage of white color is that it is conspicuous when installed in the PC.

Compared with the other advanced products that are just in black and red colors, it shows better texture.
