AMD's Radeon HD 5670: Sub-$100 DirectX 11 Starts Today

Battleforge
BattleForge is EA’s card-based online-only RTS. As the first DirectX11 title it’s of particular importance for the latest rendition of DirectX, although in this case we aren’t using any features that would be impacted by it. Even without ambient occlusion, BattleForge manages to be a rather punishing game for GPUs.
Battleforge is another game where you really have to give up some kind of quality to play at 1680 or higher. The 5670 is neck-and-neck with the 8800 GT, but the 4850 makes quick work of it.
Compared to more modern cards, the 5670 is still at the top of the $99 class, but the GT 240 is within a few frames here. The 4670 falls well behind here, with the 5670 coming out almost 50% faster in some cases.

Another nice thing about it is that it makes an inexpensive triple-head card that does not need external power, even if one of the heads needs to be Displayport. Even a single link HDMI/DVI can still support 1920x1200.SlyNine - Thursday, January 14, 2010 - link
Is the 4670 you have in your comparison charts a 4670 with DDR3 or DDR2?Also any news on the mobile version of this card or the 5380 I've seen in alot of notbooks?

GDDR3.And I don't have any news on the mobile 5000 series. Nor is there a 5830 that I have been informed of.

5830 is in the HP Envy 15.Ryan Smith - Thursday, January 14, 2010 - link
If it's in a laptop, then it's going to be a neutered Juniper. The Mobility series is always a part down, so a Mobility 5800 series part would be Juniper based.SlyNine - Thursday, January 14, 2010 - link
I'm sure I seen it in 2, including the Envy15, Perhaps I shouldn't have said "alot".But it would be good to have a review comparing the mobile solutions out there. Not to mention the throttling problems in some notebooks.
I'd love to see Anandtech do a review of the problems the Dell XPS 16 w/ Core I7 has. On A/C and only on A/C it cuts the multiplier to 7 and then uses a clock modulation. Clock modulation tells the cpu to only do work certain cycles, so you can have as many as 75% of your CPU cycles going to waste.
The end result is a Dell 1645 Core I7 running at the equivalent of 300mhz.

Full story here, and just for the record, Id be willing to let Anandtech borrow my 1645 to test if Dell doesn't fix it with this next BIOS update, which I don't see how they can 90watt AC is simply not enough.

I read through that thread yesterday. We support 50+ Dell e6500 laptops that have been problematic in other ways besides throttling, but it was nevertheless interesting to read and pass along to my fellow IT co-workers.JarredWalton - Thursday, January 14, 2010 - link
I've looked at the thread and sent Dell an email asking for comment. It's important to remember power supply (power brick in this case) efficiency, so if the brick can output 90W and it's only 75% efficient (which is probably higher than what it really achieves), power draw at the wall of up to 120W might be achievable without the need to throttle. So, it's possible that a BIOS update will indeed address the problem, but let's not jump to any conclusions just yet....I'd also say that if you're using FurMark to achieve the throttling, find something else instead. FurMark really pushes the envelope and many consider it a power virus. I understand others are saying it occurs with regular games, which is obviously a much bigger issue than with a test program that doesn't represent a real-world workload.
Anyway, if you really want to send us the laptop for testing, why not do the testing yourself and use that as the basis for an audition to AnandTech? If you go that route, I would make sure you really investigate when throttling does and doesn't occur, look at the various power profiles and try tweaking those, etc.
As a side note: with Win7 I noticed on at least one laptop that using the "passive" cooling profile caused video playback to stutter, and setting it to "active" fixed the problem. There are so many variables that you can never know 100% what might be causing a particular problem.

Jarred thanks, I'm going to take you up on that and currently I'm doing a write up on the XPS 1645 w/ RGB. I would love any suggestions or if you would like me to include anything please send them to SlyNine@hotmail.com with the subject: XPS 1645. If anyone knows any tools other then throttle stop to monitor the CPU modulation that would also be helpful.SlyNine - Thursday, January 14, 2010 - link
Yea I don't use FurMark at all, in fact I made a post recommending them not use it.With just UT3 nothing else going on the multiplier hits as low as 7 and with the brightness up halfway the modulation kicks in bringing the CPU down to 25%, that's only 25 cycles out of every 100 that's willing to do anything. Even just doing a Prime 95 run the multi is below 10, correct me if I'm wrong but isn't it supposed to be around 13?
But thanks a TON Jarred for acknowledging this, If a high profile sit like Anandtech did a story on it I'd imagen that dell would have to respond. Really this is an Amazing laptop otherwise (other then this line I have threw my screen but obviously that is covered by warranty.)
