AMD’s Radeon HD 5450: The Next Step In HTPC Video Cards

Battleforge
Battleforge is punishing enough for higher-end GPUs, but for anything below the 4670, we have to drop the quality to get playable framerates even at 1024. In this case we had to drop to Low quality to get playable framerates on the 5450.
Once we go Low, the 5450 and associated cards become playable at 1280, and more or less fluid at 1024. The 5450 continues to get around half the performance of the GT220, and once more loses to the 4550.

Why don't the Radeon "Cheese Slices" video screenshots have horizontal lines? The Nvidia ones have them...Ryan Smith - Thursday, February 4, 2010 - link
It's an artifact of stepping through the video one frame at a time with MPC-HC with the MS MPEG-2 decoder. Doing so captures the angled lines correctly, but it doesn't quite capture some of the other artifacts exactly the same because it ends up a field (basically half a frame) ahead.In motion the Radeon cards are getting it right.

Congrats Ryan, your Cheese Slices testing outside of a HTPC forum was really a big surprise for me! Keep on pushing AMD/Nvidia to realize that there's more than gamers in this world!> Horizontal 1p lines missing:
I'm also wondering normally the 1p lines are no problem in screenshots (MPC-HC and more). Maybe you shot them during the "odd movement" (1h+3v see description in Cheese Slices thread). I have now edited Post #1: screenshots only during "even movement".
This link shows it (sorry German):

1080i-1 ---> odd movement
1080i-2 ---> even movement
What's more, GT220.png and G210.png show MA in 1p and "respone - noise" but VA in the ticker, How did you manage this? Ah I see, you left a mailaddress, I will send you a mail.

Oh and the Nvidia G210 has some artifacts for the vertical lines with some pixels shifted right.silverblue - Thursday, February 4, 2010 - link
...then this might call for an article to look at it in that very light. However, is there a higher performing part for both series that can be directly compared? I'm guessing not, as they all differ in some way, be it shader numbers, ROPs or texture units. The only way I can think to do it would be comparing two 512MB 4850s to a downclocked 5870, but even if that were possible, you'll still get a performance drop due to Crossfire. Hmm.MrSpadge - Thursday, February 4, 2010 - link
5770 is as close as it gets. THere's the difference in the memory subsystem, though. Could be that the best bench to run would be ShaderMark.GeorgeH - Thursday, February 4, 2010 - link
You mention the Sapphire's heatsink quite a bit, but I didn't see any pictures of it (at least the reverse side) in the article; was that an oversight or am I blind?Ryan Smith - Thursday, February 4, 2010 - link
Oversight. I thought I had a stock photo of the rear. I'll get one in the morning.If you're really curious, it's the same heatsink that's on their 4350, which there are plenty of pictures of.

I see it now, thanks - it's actually not nearly as "bad" as I thought it'd be.Ryan Smith - Thursday, February 4, 2010 - link
