Crysis: 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.

    I'm a bit psyched at the prospect of a passive 6XXX series card. Rumour has it that Llano will be hybrid crossfire capable with such a card. It is a piece in the puzzle for my ultimate 'completely passive' yet still decently powered HTPC build.. hopefully coming to my loungeroom sometime Q3. Reply

    For the image quality. JPG introduces more distortion. Reply

    More video ports. I have 3 monitors (2x20, 1x30); and since that's not an eyefinity supported setup I stuck a 5450 in next to my 5870 to run the 3rd screen. It wasn't any more expensive than a DP-DVI adapter and came without the compatibility/reliability nightmare the adapter came with. Reply

    A lower power way to get multi monitor support. Catalyst doesn't downclock the memory if you have more than 1 monitor plugged into a video card. On a 5770, that's 30W extra when idling or doing any 2D (non-gaming) function. Plug a 2nd monitor into a 6450 and lower power consumption by ~20W.

    Ryan - will there be an addendum to cover the HTPC tests? Can you add power use during some typical apps (playing 1080P content, etc)?

    Yes, there will be an addendum. Ganesh (our HTPC/media streamer guru) will be looking at a 6450 in an HTPC setup. I can't promise what tests he'll run though, so you would have to talk to him. Reply

    In the HTPC review, I would like to see a comparison of using the hardware features for deinterlacing, deblocking, etc., compared to software such as ffmpeg.

    thanks!

    " AMD’s previous low-end product, the 80SP Radeon HD 5450, is effectively matched by Intel’s HD 3000"

    Huh? To get the HD3000 you have to spend some $200 on a cpu, not to mention a new motherboard in 100% of situations. With a $50 6450 you can buy a $50 Athlon II and have better graphics for less than half the total price. Any intel solution in this price range is going to be stripped down vs the HD3000. Celeron B810 for example. That chip is $90 but its gpu has been gutted. A $35 5450 and a $50 X2-245 together would ker-stomp the celeron B810, for less money too.

    Take the statement as forward looking rather than focused on GPU upgrades to existing systems. If you have an Athlon II and you wanted decent graphics, chances are you're already running at least a 5570, which as we point out is significantly faster than the 6450. If on the other hand you buy a new system later this year and it comes with a Sandy Bridge CPU, would you really want to pay an extra $50 to "upgrade" to the HD 5450? No, you wouldn't. You would want a card that is faster and offers more, and this is where the 6450 comes in. On the AMD side, you also have Llano coming out, which will be quite a bit faster on the GPU side than the HD 5450. Again, why would AMD continue to have their low-end discrete GPU lag behind modern IGPs? Reply

    When you get a chance to do more testing, I would love to know if it is would be a worthwhile upgrade from a Radeon HD 5450, especially in terms of power consumption. I currently have a passively cooled 5450 in my HP Proliant Microserver, running as a NAS / HTPC. (P.S. - It would be awesome to see a review on the Microserver as well).

    Would the 6450 be able to fit in the required power envelope of my system (the x16 PCI Express slot is apparently rated at a maximum of 25W, according to the marking on the motherboard)? The motherboard might well be able to go a bit higher than 25W, but I'd rather let someone else find that out :)

    What? All your questions are answered in this article. The TDP rating of the 6450 is 40% more at idle and load than the 5450. The TDP is 27W. Reply
