Sapphire HD 6990 4GB - 2. The Look, Noise and Power Consumption

Written by Sanjin Rados

UPDATED: Red camp strikes back

 

Sapphire HD 6990 4GB GDDR5 PCI-E DVI-I/QUAD Mini DP is a 30 cm long graphics card. Thanks to the 2GB memory buffer per GPU, gaming on 6 monitors should be a breeze.

As you already probably know, Radeon HD 6990 is the largest of the HD 6000 series, comparable perhaps only to the HD 5970. Our today’s sample is based on reference design but it comes with Sapphire’s sticker symbolizing twin GPU engine underneath.



3-cards-1

Sapphire HD 6990 comes with a dual-link DVI out and four mini-DisplayPort (version 1.2) outs.

Sapphire threw in a few dongles in case you require an HDMI or DVI connectors. Among them is the active single-link mini-DP-to-DVI adapter which can come in handy for connecting the third DVI display.

All the cards that launched today run at 830MHz for the GPU and come with 4GB of GDDR5 memory (2GB for each GPU) clocked at 5000MHz and paired up with a 2x256-bit memory interface.

Just like on the rest of the HD 6900 series cards, there is a BIOS switch that takes the card up to 880MHz for the GPU.

Temperatures and Noise

The central fan takes case of cooling where temperatures don’t exceed 87°C. Although the card is audible, it’s nowhere near unbearably loud. However, you’ll hear the airflow well.

Power Consumption

The card consumes around 37W in idle mode, which isn't half bad considering that a single HD 6870 consumes 22W.
On the other hand, HD 6990 consumes around 335W and if you intend to overclock it, you should know that it can draw up to 370W. This means that it will draw about 125W more than HD 6970, via two 8-pin connectors.

However, all those watts aren't in vain and the card already boasts the title of the fastest graphics cards around.

6970 vs 5970 just show again how much AMD failed with their new architecture. Hopefully they will simply return to their 5-shader architecture and call the 4-shader Cayman a failed experiment.

After the weak scores of 5870 vs 6970 I expected significant improvements from better drivers due to the brand new architecture. Now, many months later, it's safe to say that was not an issue.

I've only been buying AMD cards for years and am actually rooting for the red team, but I think it's safe for me to admit Nvidia kicked AMD's ass this gen - even though the GTX590 is not yet released, but after seeing 6990's benches it's hard to see how Nvidia would manage to not make this the fastest card on the market.

If you had included the numbers for 6950's in crossfire, the $700 US MSRP would seem a little out of whack (100$ more expensive).

That price will not be going down, unless NV pulls a rabbit out of their arse, the 590 will be 100$ more expensive. Who are buying these cards anyways?

Other than that, a fabulous card.

A very positive review about Amd. THats rare on fudzilla.

Enthusiasts. The same guys that will buy two of these, add two $100+ waterblocks, and own us all.

It's called "DRIVERS" and a new card, AMD only needs to refresh it's drivers to fully take advantage of this Dual-GPU Monster HD 6990. Good job AMD...

why do they release cards with shitty drivers??? dont make sense to ME!

Performance is really nice but power consumption and prices are starting to get out of hand.

I am thinking of buying such cards ( a 6990 or 590) but the price they are asking it's a bit exaggerated. 500 euro should be the max... the 6990 is 600 euro and I bet the GTX 590 will be 700 euro.

You're kidding right? I think you don't understand the economics. Their shader performance is about on par, regardless of being 20% simpler and requiring less transistors. That is an achievement in my book.

For people comparing SLI/CF setups, yes they are probably more economical, unless you factor in a new PSU and motherboard (and maybe CPU/memory to go with it). SLI/CF is only more economical if you already have a capable system. That is the niche these cards were created for.
