DX11: 3DMark11

FutureMark 3DMark11 is the latest addition the 3DMark benchmark series built by FutureMark corporation. 3DMark11 is a PC benchmark suite designed to test the DirectX-11 graphics card performance without vendor preference. Although 3DMark11 includes the unbiased Bullet Open Source Physics Library instead of NVIDIA PhysX for the CPU/Physics tests, Benchmark Reviews concentrates on the four graphics-only tests in 3DMark11 and uses them with medium-level 'Performance' presets.

The 'Performance' level setting applies 1x multi-sample anti-aliasing and trilinear texture filtering to a 1280x720p resolution. The tessellation detail, when called upon by a test, is preset to level 5, with a maximum tessellation factor of 10. The shadow map size is limited to 5 and the shadow cascade count is set to 4, while the surface shadow sample count is at the maximum value of 16. Ambient occlusion is enabled, and preset to a quality level of 5.

Power seems to be respectable compared to other cards, it really manages itsel properly while giving good perfomance. Although it lost at Metro against ali'd rigs, the 6990 seems to do well.

AMD's got some nice ideas there, but it's not exactly the most impressive card ever due to the numerous drawbacks.

The dual-bios switch is a pretty awesome idea even if the actual overclocking potential of the 6990 was a huge 'meh'.

I suppose these cards are never intended to be particularly sensible though and are aimed are that certain type of gamer (more money then sense, possibly).

# CrossFire in the modern worldBruceBruce 2011-03-08 09:12
There has been a dearth of mainstream motherboards with dual 16x PCI-Express connections lately. My 1156/i5 combo is a very cost-effective platform for gaming, but with high end cards, the 8X PCI-E connectivity starts to hit bandwidth limits. This card, as over-the-top as it may seem, is an excellent way to get the full performance of two 6970-class GPUs with one slot.

I know it seems ironic to talk about budget when we're discussing a $700 video card, but if I take the money I would have spent on an X58/LGA1366 motherboard and a top-of-the-heap CPU and put it towards the video card, I think it's a better bang for the $$$$.

# RE: CrossFire in the modern worldAdam 2011-03-08 09:49
I can see where you're coming from, but I dont think 1366 is expensive enough to justify buying the 6990 over a cheaper crossfire/Sli setup which will have comparable performance.

Another problem is, whilst high end cards are great fun and all that, they're currently redundant. Current PC games are becoming so heavily gimped by the console market that we're not seeing anything worth buying these parts for.
Having said that I've not played Crysis 2 yet, but it's a console port. Bleh.

Crysis 2 isn't a console port, it was developed for PC from scratch, and it will support DX11 in the final release.

Suhaib is correct. I don't know where people are getting their news from. Just because it's going to consoles doesn't mean it was PORTED from consoles. Crytek has stated multiple times that CryEngine3 was developed for the PC first, ported to consoles second.

Have you played the multiplayer demo? As soon as you start up the game, you're greeted by a "PRESS START TO CONTINUE" screen regardless of if you're on keyboard/mouse or controller (or were, I think they patched it). They pulled an Infinity Ward on Crysis 2. There's even an aim assistance option in the settings menu. If not for console, it was definitely designed for the controller, which, to me, is still showing how little most devs care about PC now.

Is that your logic? have you ever considered people who prefer controllers in the PC consumer base?
RagingShadow, I suggest you wait until the game is released.

Do you honestly think that enough people use controllers for FPS's on the PC to justify them putting the default message as "press start to continue"? Really?

# What did you expect?Olle P 2011-03-09 02:19
In terms of overclocking I don't expect a 450W card to reach very high until some more efficient form of cooling is applied.

In this case I don't count the "What the lawyers make us say" setting at 830MHz 1.12V as the reference setting, but just a safe adaptation to get the card within the PCIe standards.

880MHz and 1.175V is the reference speed, and from there the card can be overclocked a bit. How much past 900MHz is still anybody's guess though...

What a rip off.699.00 thats a hundred over the hd 5970 when it was released.The only reason it is this high, is the fact that there is no competitive card out there.An extra 2 gigs doesn't cost a hundred dollars.

# The price is right.Olle P 2011-03-09 02:22
The $700 is the price of a pair of 6970, which is essentially the equivalent but require more space, two more power cables and an extra PCIe slot.

...and is faster, quieter, and gives you the option of starting with one 6970 and upgrading later. Aside from "fastest single graphics card" bragging rights, I really don't see the point to a card like this.

Its a card that will last a long time as a high end graphics card. Its a future proof card.

They fixed it with a patch, and they've also talked about crysis 2 shipping with DX9, and being patched later to DX11.

And almost all my friends and I use controllers when we feel like it.

Adam makes a very Valid point with the Push start to continue message. Cytek can say this and say that but the game is obviously geared towards the Console market. As far as the card goes, weve seen this power struggle between Nvidia and Ati for years now. It is funny that Nvidia top 2 cards ATM have to be in SLI'd just to keep up. but soon as Nvidias 6xx series comes out then yep you guessed it balls back in Nvidia court again until Ati releases their 7xxx series. the pattern continues on. But not one person here can disagree that the PC gaming world IS being hindered one way shape or form of the badly aged current gen Console market.And until Microsoft/Sony and yes Nintendo release their next gen consoles PC gaming will be at a Tech crunch. and really until then these type are cards ARE redundant, with only a FPS gain, but a decent CPU and Crossfire/SLI setup is more then enough for even the newest of games at eye candy Resolution/Settings.

One thing that is good to know though, ONE 6990 os almost as good as TWO GTX580's. Wow, nVidia fanboys are gonna rage at this.
