Ati Radeon Hd 6970 2Gb

Manufacturer Ati

US price (as reviewed) $369 (ex tax) MSRP

Specifications :

The previous Radeon HD 6800-series got our hopes up in two ways,firstly it sounded like it’d be more than a mid-range GPU that went toe-to-toe with Nvidia’s GeForce GTX 460 cards, and secondly it wasn’t all that new. 

But while the Barts GPU of the HD 6800 looked more like an overclocked HD 5830 with a tweaked front-end unit, the Cayman GPU of the Radeon HD 6900 is a completely new design throughout.

Before we plunge into the details of the new GPU, let’s clear up the naming. 

We’re sticking with calling these cards ATI Radeons because that’s what most people know them as, and AMD has said that it’s fine with it partners gradually transitioning from ATI to AMD Graphics until 2.011. 

We still plan to switch when AMD’s Fusion APU is launched in early 2.011, as it’ll be silly to talk about a single piece of silicon that has both AMD and ATI technology.

Previously ATI has reserved the HD x900 family branding for its dual-GPU cards to give a bolder indication to the customer that a dual-GPU card should be much faster than a single-GPU HD x800-series card. However, because ATI needed the HD 5700-series to exist with the HD 6000-series, ‘Radeon HD 6800’ was already taken. 

The Radeon HD 6950 2GB and Radeon HD 6970 2GB are therefore both single-GPU cards. 

There is a plan to release a dual-GPU card based on two Cayman GPUs which we assume will be called the Radeon HD 6990 4GB. 

With the names out of the way, let’s stuck into what’s inside the silicon that makes a Cayman worthy of its HD 6900 name.

A Dual Front-End Design

While Nvidia went nuts with its Fermi design, breaking apart the elements of a typical GPU front-end and scattering them throughout the chip, 

ATI has been much more reserved. 

However, we’ve been expecting ATI to get a bit more radical for a while – after all, a GPU with only one tessellator and one setup engine is starting to look a bit anachronistic these days. 

While the Barts GPU added merely had a tessellator upgrade (to what ATI is called its 8th Gen Tessellator, which allows off-chip buffering) the Cayman design of the Radeon HD 6900-series has two entire front-end units.

There are some obvious advantages of having two front-end engines: you get two setup engines, two 8th Gen Tessellators, two geometry engines and the ability to send twice as much work per clock to the stream processors than before. 

ATI claims that the HD 6970 2GB has up to three times the tessellation rate of the HD 5870 1GB. 

These two front-end units can also load-balance the work flowing to them, and ATI has implemented ‘asynchronous dispatch’.

The new Cayman GPU of the Radeon HD 6970 2GB has two Fron-End Engines.

Asynchronous dispatch is like the ability of Nvidia’s Fermi GPUs to work on two distinct kernels simultaneously. 

However, ATI says that its technology is ‘completely new in the marketplace’ as it allows multiple, different programs to execute on the GPU at the same time. 

‘It’s not like other solutions where you [only] have one program that can spawn multiple kernels to run on the graphics card, you can genuinely have multiple, different applications running on the GPU at the same time’ Dave Bauman, Senior Product Manager, told us.

This should make the GPU more flexible for general-purpose work, the GPU will act more like a modern CPU. 

The two bidirectional DMA (Direct Memory Access) engines of the GPU are also pitched as enhancing the GPU Compute capabilities of the GPU, as they allow two simultaneous reads or writes or a simultaneous read and write per unit.

However, we’re unsure of the need for such advanced capabilities when it comes to gaming. 

A game runs as a single application, meaning that Nvidia’s technology is perfectly adequate, a game can invoke a DirectCompute kernel and throw it, as well as DirectX shader code, at Fermi GPU without concern.

Where the ATI technology will be useful is if many different applications try to use your graphics card, especially if they don’t have the courtesy to wait until you’ve finished gaming before doing so. 

It’s not impossible that anti-virus applications could be written in OpenCL, for example, as virus scanning.

Innovative dual Gpu design is also dramatically quieter than competitive products 

The Nvidia Geforce Gtx 590 is the world's fastest graphics card and the world's quietest dual gpu card too!

Nvidia engineered the Gtx 590 to be the world's quietest dual Gpu product. 

It features a special cooling system and dual vapor chambers which deliver both astounding performance and acoustics. 

Measured with a standard decibel meter, the Gtx 590 clocks in at 48dB, more than two times quieter than the closest competitive product under full graphics load. 

The Geforce Gtx 590 also incorporates a functional Led to let users know the operational state of the Gtx 590 card.

Nvidia today introduced the GeForce® Gtx® 590, the fastest dual graphics card available today which also happens to be the world's quietest too. 

Powered by dual Nvidia Fermi™-class gpus on a single card, the Gtx 590 is designed for über enthusiasts and those looking to build the ultimate PC gaming rig.

With a combined 1024 Nvidia cuda® architecture cores, 3gb of gddr5 memory, 6 billion transistors and over 2200 individual components all packed into an 11 inch dual slot card, the Gtx 590 delivers a staggering 32 tessellation engines that can power today's cutting edge DX11 games at resolutions of 2560x1600 and higher. 

With four separate video outputs on each card, consumers can configure their PC with four independent displays, or they can span their gaming across 3 3D displays, at a resolution up to 5760x1080 for an intense, immersive, stereoscopic gaming experience utilizing Nvidia 3D Vision™ Surround technology.

Like all Nvidia "DX11 Done Right" GPUs, the Gtx 590 delivers the world's fastest performance for dx11 games(i). 

And with Nvidia Sli® technology, the industry's most scalable multi gpu platform, gamers can increase their pc's gaming performance by adding a second Geforce Gtx 590, for an incredible quad sli gaming mode.

Nvidia engineered the Gtx 590 to be the world's quietest dual gpu product. It features a special cooling system and dual vapor chambers which deliver both astounding performance and acoustics. 

Measured with a standard decibel meter, the Gtx 590 clocks in at 48dB, more than two times quieter than the closest competitive product under full graphics load. 

To the human ear, this difference means the Gtx 590 delivers a 3d gaming experience that is typical of a quiet library. In comparison, the competition's product is more on par with a busy freeway.

"The Gtx 590 is the best dual gpu product ever built," said Drew Henry, general manager of Geforce gpu business at Nvidia. 

"With leading performance, support for multi-monitor 3d gaming, quad sli, and an acoustic envelope that begs to be heard for how quiet it is, the Gtx 590 epitomizes what a perfect dual graphics card looks, performs, and sounds like."

With an estimated selling e-tail price starting at $699 Usd, the GeForce Gtx 590 is available starting today from the world's leading add-in card partners, including Asus, EVGA, Gainward, Gigabyte, Inno3D, MSI, POV, Palit, and Zotac.

Video card buying tips

Introduction

With the popularity of computer gaming video cards are becoming of of the most commonly upgraded components in a computer. 

However, purchasing a computer video card can sometimes be a very confusing and frustrating task. 

Before purchasing a video card, keep the below recommendations in mind.

Connection

Today, there are three bus (slots) a video card is capable of connecting to. 

Although with most modern computers today it'll be either PCI-E or AGP. 

Before buying a new video card make sure you get a video card that will be compatible with the available slots in your computer.

PCI-E or PCI-Express was approved as a standard on July 2.002 and is the latest computer bus found in computers. 

PCI Express is designed to replace PCI and AGP and is available in several different formats : x1, x2, x4, x8, x12, x16 and x32. 

AGP or Advanced Graphics Port, is a new standard available on Pentium II and later motherboards. 

Introduced in 1.997, AGP is a 32-bit bus designed for high demanding video cards. 

AGP has a direct line to the computer memory, which allows 3-D elements to be stored in the system memory instead of the video memory and is available in three different standards (1.0, 2.0, and 3.0). 

PCI or Peripheral Component Interconnect, was first introduced in 1.992. 

Although still in use most computers today will have an available AGP slot and should be used instead of PCI. 

How do I know what computer video card I have?

Power supply

Today's video cards are one of the must power hungry devices in your computer. 

Make sure that your power supply will meet the requirements of your video card. 

Many video cards will require a 500W or more power supply. 

If your computer doesn't meet the power requirements you'd need to upgrade the power supply before being able to install the new video card.

Memory

Another important consideration when purchasing a video card is the amount of video memory the card has. 

Like system memory, the more memory located on the computer video card in most cases the greater capability of the video card. 

Today, we suggest at the minimum a video card with 2 gb mb of video memory.

Other considerations

Below are some additional considerations you may want to think about when buying a video card.

Ports - Many newer video cards will only have a DVI connection or both a VGA and DVI connection. 

If you're using a video card with a monitor that has a VGA connector it can still be used, but you'll need to also purchase a DVI to VGA converter if not included with your video card.

Chipset - There are dozens of different video card manufacturers. 

However, there are only two major chipset manufacturers; Nvidia and ATI. 

Although both are great manufacturers there can be great big differences between the two as far as performance. 

Before buying any video card it's a good idea to look up a hardware review on the video card before purchasing it if you're concerned about it's performance.

Size - If you have a smaller computer case fitting some of the new video cards in the computer many not be possible. 

Video cards today are much larger than older video cards because of their increased capabilities and need for cooling fans. 

Make sure your case is going to have room for a new video card. 

The only way to do this is to open the case and physically look.

Warranty - How long is the warranty and what does it cover.

Support - Is the technical support number a free number and is it open 24 hours, 7 days a week? 

You can find contact information for all major video card manufacturers on our video card contacts page.

Price range

The price range can vary depending on the brand of video card, amount of memory, the interface used, and other available options. 

In general prices can range from $100 to $1,500 Usd.

Where to purchase

For best price we often recommend that users purchase all computer hardware online. 

You'll be able to look at other customer reviews and get a much lower price. 

If you're uncomfortable buying online or want to talk to a sales rep you can always visit a local retail store and then buy online.

DirectCU

Direct cooling for 20% cooler than reference

If the GPU is the heart of a graphics card, then the cooling device would be its lungs. 

Without it, the graphics card would not be able to "breath" smoothly, causing it to break down or even cause the entire system to fail. 

For ultimate cooling, ASUS DirectCU thermal technology developed the ideal heat banishing copper in exclusively designed heat pipes for direct and fast heat dissipation.

Asus Directcu technology

Thick copper heatpipes are accurately positioned in direct contact with the GPU surface so heat is transported and dissipated efficiently to the heatsink - achieving a 20% cooler performance than reference. 

Since heat is carried away faster, fans can spin at a lower speed thus resulting in quieter performance than reference.

Ken Brown, a spokesman for Nvidia, told the media that Kepler silicon will be available this year, but now it seems production of graphic cards will not happen until late 2.012. 

So far, we have been under the impression that Kepler cards could be arriving just in time for Christmas, even if Nvidia already had said at the International Supercomputing Conference in June that the new cards may be delayed by a month or two.

Kepler will be succeeding the Fermi architecture and use a 28 nm production process. 

There have been rumors that Nvidia is struggling with the 28 nm production and that manufacturing is causing the delay. 

Of course, Nvidia isn't commenting on the delay and no chip manufacturer would ever give a statement on yield issues anyway. 

However, Nvidia is under pressure of getting Kepler out on time and especially get to Kepler right. 

The current Fermi architecture was delayed several times and had a less than perfect launch.

According to information released by Nvidia so far, Kepler cards will triple the dual-precision floating point performance of Fermi and hit up to 6 dp GFlops, while its successor Maxwell (scheduled for a 2.013 release) is expected to with almost 16 dp GFlops. 

These are big promises and Nvidia wouldn't want to miss them.
