The launch of Trinity gives AMD a more worthwhile platform for mainstream users put-off by the pricing of the AMD FX and Intel Core i5/i7 product lines. Trinity offers plenty of bang for your buck, with true quad core CPUs and world class integrated graphics starting at about US$100. Often lost in the value equation is the cost of motherboards. Traditionally AMD boards have been more affordable than Intel counterparts sporting the similar features, and we're glad to say that this trend continues.

The first FM2 board we reviewed, the ASUS F2A85-M Pro at US$130 is actually the most expensive model currently on the market. Though we were pleased with the ample feature-set and in particular, the inclusion of ASUS' excellent Fan Xpert 2 fan control software, we don't feel it's the type of board that the majority of prospective Trinity buyers are looking for. Our general rule of thumb is the motherboard should not cost more than the processor.

A value processor isn't much of a value without a comparable motherboard and at US$80, the Gigabyte F2A75M-D3H more closely fits the bill. Notably, this model uses the older A75 chipset which debuted with Llano/FM1 last year. The latest A85X chipset incrementally improves the Trinity experience, only adding the option for a 8x/8x CrossFireX mode and a couple of extra SATA ports. The budget A55 chipset, on the other hand, is very basic, lacking native SATA 6 Gbps and USB 3.0 controllers. A75 is a reasonable compromise between the two.

From the look of it, the F2A75M-D3H has almost everything offered by the A75 chipset but nothing more. The board has six SATA 6 Gbps ports with some RAID options, two USB 3.0 ports and an onboard header, S/PDIF and HDMI. Missing are a DisplayPort output, eSATA, and wireless connectivity options like Bluetooth and WiFi.



The box.



Package contents.

Like its feature-set, the F2A75M-D3H's bundle is quite bare. Just the basics are included: Documentation, driver disc, I/O shield, and a couple of black SATA cables.

PHYSICAL DETAILS

The F2A75M-D3H is laid out like other AMD microATX motherboards. Most of
the connectors are at the edges of the board where they are easily accessed,
though the 8-pin EPS12V connector is in the top left corner; if you have a large third party cooler and a case with a top-mounted power supply, it could be a real pain to connect.



There are two full size PCI-E slots though the bottom one runs at only 4x due to chipset limitations, six SATA 6 Gbps ports, an onboard USB 3.0 header, and three 4-pin fan headers.



None of the SATA connectors are on the side though they are far from the main 16x PCI-E so interference is unlikely. Two fan headers are at the center which is perhaps accessible than along the top edge which is the norm.



Cooling the FCH is a small, low profile heatsink attached with the usual pushpins.



By the looks of it, the board utilizes a simple 4 power phase design for voltage regulation. The VRM circuitry is bare with no direct cooling.



Being a budget board, there aren't as many options on the back panel, just the standard fare like HDMI, S/PDIF, and a pair of USB 3.0 ports.

BIOS/UEFI

Since our last Gigabyte motherboard review (the P67A-UD4), they've followed suit with competitors like ASUS, updating to a UEFI BIOS with a fancied graphical user interface.



The F2A75M-D3H doesn't have a ton of options so some of the menus look a bit sparse. For example, the voltage and frequency settings have only a few items but they're placed on separate pages. It would not only look better but also be more convenient if they were grouped together.

BIOS Summary: Gigabyte F2A75M-D3H
Setting
Options
BLCK/PCIe Clock 100 to 140 MHz
Graphics Clock 300 to 2000 MHz
NB Clock 800 to 6000 MHz
Memory Frequency 800 to 3360 MHz
CPU Vcore Up to +0.300 V
NB Core Up to +0.300 V
DRAM Voltage 1.200 to 1.900 V
Memory Timing Options Advanced
UMA Frame Buffer 256MB, 512MB, 1GB, 2GB

Compared to enthusiast class boards, the settings available are very simplistic and the limits on voltage are a bit restrictive and there's no undervolting at all. The BLCK clock can only be raised up by 40 MHz over stock but anything more might actually be dangerous for the hardware as it's tied to the PCIe clock. As a result, it's probably not possible to raise the BLCK frequency to a substantial level without creating instability, making overclocking, at least with a locked non-K series chip, very difficult.

Fan control settings are available for all three fan headers. There are two presets, "Normal" and "Silent", as well as a manual mode which allows users to adjust the slope from 0.75 to 2.50 PWM value / C in 0.25 increments. Unfortunately you can't define maximum/minimum temperatures or fan speeds from this menu.

Estimating DC Power

The following power efficiency figures were obtained for the
Seasonic SS-400ET used in our test system:

This data is enough to give us a very good estimate of DC demand in our test
system. We extrapolate the DC power output from the measured AC power input
based on this data. We won't go through the math; it's easy enough to figure
out for yourself if you really want to.

Testing Procedures

If available, the latest motherboard BIOS is installed prior to testing. Certain services/features
like Indexing, Superfetch, System Restore, and Windows Defender are disabled
to prevent them from causing spikes in CPU/HDD usage. We also make note if energy
saving features like Cool'n'Quiet/SpeedStep or S3 suspend-to-RAM do not function
properly. If a WiFi adapter is present, it is disabled unless the system lacks wired ethernet.

Our main test procedure is designed to determine the overall system power consumption
at various states (measured using a Seasonic Power Angel). To stress the CPU, we
use either Prime95 (large FFTs setting) or CPUBurn depending on which produces higher system power consumption. After 10~15 minutes of load (when temperatures stabilize), we also measure the hottest points on the external heatsinks using an infrared thermometer. To stress the IGP, we use FurMark, an OpenGL benchmarking and stability testing utility.

Finally, storage subsystems are tested briefly using CrystalDiskMark (1000 MB of 0x00 fill test data) and a Kingston HyperX 3K 120GB solid state drive. For USB and eSATA we use an external eSATA/USB 3.0 dock to connect the drive.

TEST RESULTS

Power Consumption

On light load, the A8-5600K and F2A75M-D3H is one of the most energy efficient desktop combinations we've encountered, hitting 17W DC when idle, an astonishing 5W improvement over the ASUS F2A85-M Pro.

On heavy load, the scales tip in the opposite direction, with the F2A75M-D3H using 2W more compared to the F2A85-M Pro when encoding video with TMPGEnc and running synthetic CPU and GPU stressors.

Unfortunately it is difficult to ascertain exactly how much of the energy draw
is generated by the processor alone, as the amount of power pulled from the
AUX/EPS12V connector depends on how board power regulation has been implemented. As a proportion of total system draw, the AUX/EPS12V draw on the F2A75M-D3H was noticeably higher than the ASUS F2A85-M Pro. This typically indicative of a more simplistic voltage regulation design that also correlates with better efficiency under low load.

Cooling

To test the board's cooling, we stressed the CPU for ~15 minutes with Prime95/CPU Burn. Temperatures of the boards' chipset and VRM heatsinks (if applicable) were recorded using a spot thermometer. The highest temperatures were taken for comparison.

As the F2A75M-D3H lacks a VRM heatsink we recorded the temperature of the hottest exposed chip instead, so naturally it was substantially higher though we didn't encounter any stability issues (we've also seen much worse temperatures in the past on exposed VRMs). The FCH heatsink did a fairly good job however, running somewhat cooler than the F2A85-M Pro.

Fan Control

The fan control options in the UEFI/BIOS are fairly simplistic and it's not much better on the desktop. EasyTune, Gigabyte's multipurpose tweaking and monitoring tool, offers a little more functionality but it's rudimentary at best.

EasyTune adds the option to adjust the temperature range and the minimum fan speed but the maximum fan speed is locked at 100%. It also only allows you to choose two points so changes in fan speed are completely linear.

Once again, if you're Windows user, a better fan control experience is available in the form of SpeedFan. Properly configured, it can control all three fans, though SYS_FAN1 only works with voltage control (3-pin) and the same control is tied to the voltage of CPU_FAN. To enable the fan controls, find the "IT8728F" chip in the advanced menu and change its PWM 1-3 modes to "software controlled."

We also discovered through trial and error that the temperature Gigabyte specifies as "System" corresponds to the area around the VRMs to the left of the APU socket. This is a good location for a temperature sensor as the circuitry in that location runs quite hot and lacks cooling aside from any spill-over airflow from the CPU fan.

Boot Performance

To test boot time we optimize the BIOS menu by setting the hard drive and other delays set to minimum, taking care not to disable common functionality like USB support, POST messages, etc. and measure the time it takes to reach the Windows loading screen (we stop here because this is the point where the O/S drive speed becomes a factor).

The boot process on the F2A75M-D3H is fairly fast, hitting the Windows loading screen in about 12 seconds.

Storage Subsystem Performance

To test storage subsystems we use CrystalDiskMark (1000 MB setting with 0x00 fill test data) and a Kingston HyperX 3K 120GB solid state drive. The drive is connected to an external dock for eSATA and USB 3.0 benchmarking (limited to 3 Gbps and 5 Gbps respectively unfortunately).

SATA

As A85X chipset is only a minor update of the A75 chipset, the speed of the Gigabyte F2A75M-D3H's native AMD controller was very similar to that of the ASUS F2A85-M Pro.

USB 3.0

Strangely we saw a significant disparity in USB 3.0 performance between the two FM2 boards, with the Gigabyte model delivering a good 30~40% improvement in both sequential and random 512K reads and writes against the ASUS board with its USB 3.0 Boost feature enabled. We cannot account for this discrepancy.

FINAL THOUGHTS

Compared to the more expensive ASUS F2A85-M Pro, the Gigabyte F2A75M-D3H lacks a DisplayPort connector, eSATA, and 8x/8x CrossFireX. However, you could argue that most monitors still don't use DisplayPort, USB 3.0 will replace eSATA (or an internal SATA port with a eSATA adapter is a simple alternative), and CrossFireX is unlikely to be used in a value APU-based system. The main things expected in a modern motherboard are present, namely SATA 6 Gbps and USB 3.0, native to the A75 chipset.

Also missing are a few intangibles not clearly specified in the features list. Users who heavily overclock to get the most for their money will be disappointed as the UEFI/BIOS is a bit restrictive. All the basic frequency and voltage settings are available but in a narrow range. It's also not as well cooled as most motherboards due to the absence of a VRM heatsink. The fan control system is rudimentary though all three fan headers are controllable, which is rare on such an affordable board. Windows users have the option of using SpeedFan as a more capable replacement to Gigabyte's EasyTune utility.

The F2A75M-D3H has outstanding idle power consumption at 17W DC (27W AC measured at the wall), a sizable 5W less than the ASUS F2A85-M Pro. If you're concerned about energy efficiency, it's one of the more frugal options for a low demand system like a server or home theater machine. However, the harder you push it, the more it uses; on full load, it ended consuming a couple of watts more than the ASUS board and we surmise that trend would continue with a higher power or overclocked processor.

The Gigabyte F2A75M-D3H doesn't offer a lot of features but that's forgivable given the price. It's a better fit than the premium A85X models as Trinity is AMD"s value platform. If you're really strapped for cash, boards based on the A55 chipset start at ~US$50 but lack pretty much everything mentioned above. An A75 board for US$80 hits much closer to the sweet spot.
