ASUS EAH5450

The Asus EAH5450 is the bottom of the line for AMD Radeon HD 5000 series.  The HD 5450 was released September 20, 2010.

The HD 5450 features a basic GPU which for those who need a discrete video card. The Asus HD 5450 uses 19W maximum and 6.5W at idle which is comparable to integrated graphics.

The GPU is rather small at 59mm². The small size means many more can be made for a given wafer which is typical at the low end of the range when compared to more expensive GPUs that are larger in size.

While this card uses very little power, we should point out that new power supplies are more efficient which can multiply the power savings. The low cost Corsair CX-430M is rated 80PLUS bronze while the more expensive AX860i is 80PLUS platinum. Eventually better quality PSUs will find their way into the low end of the market.

The card we have is the faster 650 MHz with 512MB DDR3 version, the more expensive 1024MB version is not worth the cost. The DDR2 cards run at 400MHz while the DDR3 versions range up to 800MHz. The HD5450 also ranges from 400 MHz to 650 MHz. The Asus EAH5450 is near the top of the range.

Better value would be seen with more shader cores than VRAM. CrossFire is possible through the PCI Express bus but better value would be seen with a better card. Remember the old adage, twice nothing is still nothing. Shader cores matter much more than VRAM capacity.

For surfing the internet the browser does not need significant graphics performance. Many older games actually will run on even more modest VRAM configurations.

The HD 5450 also is ideal for a media center machine. Using our PA238QR the combination maintain the EPAET Gold rating. Sam HD: The Second Encounter is playable and can hold 60 fps most of the time at the game’s lowest settings. Better results would be seen with older Xbox or PS/2 period games.

At idle you can expect a temperature of 45-50°C but once pushed to 100%, the temperatures will rise to ~80°C. Even with Furmark running for the full 15 minutes did not cause the card to overheat. Our Corsair Carbide 300R has excellent air flow which unquestionably benefits this card immensely.

The heatsink for the HD 5450 is attached with thermal epoxy. Typically the thermal gradient is much better than the typical pad used with fan coolers. Artic MX-4 is about 8.5 W/mK and thermal epoxy can reach 20 W/mK. The Asus EAH5450 depends on the chassis air flow for cooling.

The EAH5450 comes with a low profile bracket that is helpful for those who have a media center chassis with limited space.

Modern video cards that feature HDMI now routinely also feature integrated HD audio. Often a TV will drive the sound system so HDMI included audio in the cable specification. Older cards like our GTX 260s use a dongle to provide HDMI connectivity and a cable to the S/PDIF header on the motherboard.

Using HDMI, PowerDVD BD Advisor reported that HDCP was not working properly. This prevented movies from playing.

HDMI HDCP

The HDMI standard includes High Definition Content Protection. Asus has failed to implement that preventing this card from being used for BD video viewing.

UEFI

We have inquired several times with Asus for a UEFI VBIOS for our card but they have not responded with anything useful. UEFI GOP is needed to allow Windows 8 fast boot to support UEFI and GPT boot disk.

Disgruntled, we have been forced to abandon using this card for Windows 8 and 10.
