Radeon HD5450 Video Card Specifications

I mentioned in the introduction that the HD5450 had hardware specs well below anything we've seen so far in the HD5xxx series. You can see the HD5450 specs in detail a little further below, and they're nothing to brag about, compared to the HD5670, until you get down to the power numbers. Then, it starts to make sense, as ATI has done everything they possibly could to get these numbers down to where they are. In a typical HTPC box, everything is jammed in tighter than sardines in a can, and the low profile of the sleek, shiny chassis only allows for small fans on the back. So, power is King. If the device consumes power, it had better do something useful with it, and not just dissipate it away, as waste heat! While the specs give us a good clue to the performance of the HD5450, ultimately, it's the real-world performance we care about, the design tradeoffs that were required to achieve it, and the price for that performance. This graphic puts the general pricing v. performance strategy in perspective:

But before we get to our detailed teardown and testing, let's look at the actual HD5450 specs:

Radeon HD5450 Specifications

  • Engine clock speed: 650 MHz
  • Processing power (single precision): 104 GigaFLOPS
  • Texel fill rate (bilinear filtered): 5.2 Gigatexels/sec
  • Pixel fill rate: 2.6 Gigapixels/sec
  • Anti-aliased pixel fill rate: 10.4 Gigasamples/sec
  • Memory clock speed: 800 MHz
  • Memory data rate: 1.8 Gbps
  • Memory bandwidth: 12.8 GB/sec
  • Maximum board power: 19.1 Watts
  • Idle board power: 6.4 Watts

OK, tired of looking at numbers, let's take a closer look at the hardware, then? ATI was kind enough to send us a sample of the 512MB reference design video card with passive cooling, so let's examine the ins and outs.

is ATI Radeon HD5450 compitable with intel dual core 2.8 Ghz processor ?
Please reply as early as possible

Yes. All video cards are compatible with all processors. Just make sure the motherboard has a PCI-Express graphics slot.

# Open up the box and look inside.Bruce 2012-03-08 08:29
Wikipedia has some good pictures on the PCI Express page that show what they look like

Is is good foor games?Will it play them fast? I don't know so much about hardware and stuff...

This card is on the low end of discrete graphics.
It's really better suited to a Home Theater PC.

I see there is what looks like a fan connector on the card - is this correct and if so what would be the power specs for a fan?

If you look at some of the other HD 5450 cards out on the market (Newegg has 34 models for sale, 2+ years after launch...!) you wll see that many of them have active cooling, with a fan plugged into this very same header. It's only two pins, so don't expect PWM or anything, just straight DC with no speed monitoring.

The PCI slot has to have the little gap thing, the oppisite way around that does the graphics card have so for instance -- ---- and ---- -- and most of all if the the ports on the graphics card are pointing toward the outside, etc.

# Re Fan ConnectorRoger 2012-06-02 18:10
Thanks for that Bruce,

Just to clarify such a connected fan would be of similar size and watts etc. to an inbuilt one?

Like I have a spare fan DC 12v 0.11A which is probably ok and another which is DC 12v 0.70A which is probably too powerful?

# Yes, again....Bruce 2012-06-03 06:58
That's the idea. It's not going to be an exact science, but most fans that are small enough and thin enough to fit on that card's heatsink will be fine. I've been assuming that you want to cool the GPU on the HD 5450 with this fan... right?

# Thats right Bruce...Roger 2012-06-03 22:01
I figure one cannot have enough fans (especially where I live in the tropics) so I might as well use a spare fan to play on the heatsink. The card will be on the bottom of the mobo with the heat sink facing down so I will mount the fan on the case bottom facing up to the heatsink.

Thanks again

I badly needed an htpc graphic card for my htpc. I am really having a hard time choosing because i really don't have any idea with these kind of things. But anyways, you're post is quite helpful. Thanks!

It is not good for high resolution games.
It was designed for HTPC use, which is much less demanding.
Plus, it was released three years ago, that's a LONG time in video card history. Why are you interested in it now? Can you even buy one in your location?
