AMD's Radeon HD 6450: UVD3 Meets The HTPC
by Ryan Smith on April 7, 2011 12:01 AM ESTCrysis: Warhead
Kicking things off as always is Crysis: Warhead, still one of the toughest games in our benchmark suite. Even three years since the release of the original Crysis, “but can it run Crysis?” is still an important question, and for three years the answer was “no.” Dual-GPU halo cards can now play it at Enthusiast settings at high resolutions, but for low-end cards even Mainstream/Medium quality is nearly out of reach.
We’re throwing in a 1680 chart now and then just to showcase where the Radeon HD 6450 and GT 430 stack up compared to our usual bulk of cards. It takes a lot of cutting to make a $50 card, and the end result is a fraction the performance of a $100 card.
Moving on to more playable settings, we first look at 1280x1024 at the lowest quality setting: Performance. The drop in quality between Performance and Mainstream is quite severe, so once we get to 1024 at Mainstream you’ll understand why we’re using Performance here. In any case the Radeon HD 6450 is actually very playable at this resolution in exchange for the limited graphical quality. Crysis can be quite easy to run, you just have to give up the fancy graphics to get there. Compared to the 5450 the performance jump is quite remarkable; even though the 6450 only has an equal number of ROPs, the jump nearly matches the twofold increase in SPs. So for Crysis we’re definitely shader and/or bandwidth limited.
At 1024x768 mainstream quality, the performance drops across the board in spite of the lower resolution. The 6450 is the first card to crack 30fps, and at 32.9fps it’s only barely playable. The performance gains versus the 5450 are still over 50%, but it’s not quite the large gap we saw at 1280. As for the 5570, here it’s ahead of the 6450 by 20fps. And this is the main problem the 6450 is going to face in the performance race: cheap 5570 cards with more than twice the horsepower are going to easily overpower it. The 6450’s advantage is in power consumption and all that follows.

"... and this is what happens when the 5570 and GT 430."Typo or unfinished sentence?

"Even a slight discount on a more expensive product blows the entire lineup out of the water, and this is what happens with the 5570 and GT 430."In other words, the 5570 and GT 430 with only a minor discount on pricing blows away the 6450, at least from a pure performance perspective. Power and potentially HTPC use still could go to the 6450.

So you buy an APU - you get stunning graphics.You bought an Intel CPU - the extra $50 is what you pay to get a great CPU and HD graphics.
Honestly, this is for joe soap and his HD monitor and will probably be branded as such!

It might also be nice for a productivity Eyefinity setup. I can't wait for AT to get a multi-monitor setup in their lab.khimera2000 - Thursday, April 7, 2011 - link
I cant wait till anandtech gets a multimonitor setup. then i can stop skimming the video card reviews :DIn this modern age EVERY video card being released has the ability to drive at least two displays, and with Eyefinity, and Nvidia's offering I consider reviews incomplete unless they use ALL the technology there ment to drive. as of this moment this has not happened here. without the support of this I can only assume... and I hate assuming when im reading a review.
As it stands, without the ability to test Eyefinity and similar set ups I dont think this place will ever be a final deal maker. and that's upsetting because if they cant get three monitors in for a normal test bed, we will probably never see reviews on how well other displays work in eyefinity.
considering that the 5xxx came out in 2009, two years have passed since that fan fair (give or take), there really is no excuse not to have it right now.

I enjoy the tests on low end and low power graphics cards. One query though. Is the Radeon HD 5670 such an rare beast that no one has performance information? The HD 4670 was a wonderful upgrade for people that had OEM systems without the power supply to drive faster cards and it was recognized as that and reviewed quite well. Why was it's successor so ignored? Will there even be a successor in the 6xxx series?Ryan Smith - Thursday, April 7, 2011 - link
We keep a rolling database of performance results for GPU articles. The last time we did a low-end GPU article was with the GT 430 6 months ago, so we effectively didn't have any recent results for anything below a GTS 450. So for everything here below that, we had to rush to get results over a 2 day period. The 5670 was excluded because it's not particularly close in performance or pricing to the 6450. Everything we needed to say about how AMD had faster cards was covered by the 5570, which uses the same Redwood GPU anyhow.Anyhow, the 5670 does have a successor in Turks. Turks hasn't made retail yet so I can't say a whole lot about it, but its configured very similarly to Redwood. If and when it gets a retail release, you can expect to see a comparison to the 5670.

Cheers!I did not mean to sound as if it was a problem that card was omitted from this test. I just found it odd that it was never reviewed at all on Anandtech (and very few other places as well) since the 4670 had made such a big splash.
Your articles are always on the top of my list a resources and I thank you for them!

The 5670 WAS reviewed on Anandtech:http://www.anandtech.com/show/2917
and since this review compares the 6450 closely to the 5570, a look at the 5570 review will give you an idea of where the 5670 bar would be in this article's graphs:

The 5670 is the fastest card AMD or Nvidia ever released that didn't require a PCIE connector, although since Ryan not-so-subtly referred to a 6000-series replacement to 5670, that won't be the case much longer!

Not quite true.There's a 5750 that is "green" and doesn't require a PCIE connector.
