Radeon Hd 5570 Driver Windows 7

It's graphics card season over again, and AMD is leading the charge with a new flagship GPU, the $550 Radeon HD 7970.

Information technology's the kickoff of their new 7000 series, which are built around a new shader compages that AMD has dubbed Graphics Core Next (GCN). The new architecture is based on the 28-nanometer process, and follows 40-nanometer Radeon Hard disk drive 6000 series, which were launched mid-December final year.

That dice shrink is the critical. Past manufacturing GPUs on a smaller process, AMD is able to pack more transistors into a smaller space, reducing ability consumption while improving performance. Thanks to the tighter fit afforded by the 28-nanometer procedure, the Radeon HD 7000 serial has room for a whopping 4.3 billion transistors — the Radeon Hd 6000 series had 2.6 billion. We'll see the difference the die shrink makes firsthand, one time we're take a gander at testing results.

The 7900 series packs 32 clusters of GCN compute units, each behaving much like an individual CPU core. That ways they tin schedule their own tasks and manage workloads independently — AMD is focusing on versatility hither, as these new cards are designed to be capable compute engines for not-gaming tasks. To that end, the Radeon Hard disk drive 7900 serial will also offering up to 768KB of read/write L2 cache, and amount nosotros'd normally but run across on proper CPUs.

Under the Hood

The carte packs a worthy set of specs. Under the hood of the reference bill of fare are 3GB of DDR5 Retentivity, with a 384-bit retentivity bus. That's a lot of memory and bandwidth, to push a lot of information, and pixels back and forth – AMD is rolling quite a few new features into this launch, including back up for 3D beyond iii displays on a single carte du jour, so it'll demand it. This carte (and architecture) is besides built with multiple-displays at heart. Yous'll discover DVI, HDMI, and ii mini-DisplayPort connectors. The card is theoretically capable of supporting a maximum of 6 displays with the aid of a DisplayPort ane.ii hub, though those haven't actually hit the marketplace notwithstanding.

Why only i DVI port? It isn't needed. An HDMI to DVI adapter is bundled with the graphics card, if you lot'd similar to proceed using ii DVI ports. There's also a mini-DisplayPort to DVI adapter, so y'all can use 3 DVI displays if you lot'd like, right out of the box. But AMD is betting that nigh users buying loftier end graphics cards will have also picked up monitors equipped with next-generation connectors.

The Dual Bios toggle switch we saw on the Radeon Hard disk 6990 makes a welcome comeback. It toggles the card's bios betwixt ii modes. The starting time setting is unprotected, allowing you to tweak the overclocking settings with AMD'due south Overdrive software. The second setting locks the card at its factory defaults, if you'd rather play it safe.

There are quite a few changes in store with the new Radeon Hd 7000 series, non the to the lowest degree of which is the new compages.

New Software

AMD App Acceleration: Flexibility is cardinal to AMD's strategies: cards like the Radeon Hard disk drive 7970 will exist aimed at gamers, but the 7000 series as a whole is meant to address a irresolute PC landscape.

Video editing applications like CyberLink'south PowerDirector have long touted support for GPU dispatch to speed up workflow, by fashion of Nvidia'due south CUDA and AMD's Stream technologies. And media players similar ArcSoft's Total Media Theater can make utilise of dedicated graphics hardware to improve playback for 3D Blu-ray movies, or when converting 2d media into 3D.

Web browsers are also baking in hardware acceleration, improving HTML5 performance, or Flash and Silverlight video playback. Fifty-fifty productivity apps similar Microsoft PowerPoint will benefit from a GPU, offloading some of the image editing tasks from the CPU onto the graphics card to boost performance.

That said, if you're just using your PC to watch YouTube clips and edit PowerPoint presentations, you don't demand to worry about making room in your budget for a $550 graphics card. But AMD is hoping to convince users who are fed upwards with poor integrated graphics operation that an cheap 7000 series GPU can put a fleck actress oomph into their everyday tasks.

AMD Video Codec Engine (VCE): The Video Codec Engine built into the Radeon Hd 7000 series GPU will provided dedicate hardware acceleration for media tasks. It'southward part of AMD's App Acceleration front, offering a multi-stream H .264 HD video encoder, and "faster than existent-time" HD video encoding.

AMD PowerTune Technology: PowerTune was introduced back in the with the Radeon Hard disk drive 6900 series, and it's been refined for the Radeon HD 7000 serial. Information technology's designed to operate much like AMD's Turbo Cadre, or Intel'south Turbo Boost technologies. When the graphics carte du jour detects that information technology isn't operating at its maximum potential ability threshold, it dynamically adjusts its clock speeds, to hit that power ceiling. Put simply, the card will automatically overclock itself while in apply to brand sure it'south delivering the nigh performance it perchance can.

AMD ZeroCore Ability Applied science: ZeroCore is essentially PowerTune in reverse. When the card ins't in use, information technology dials downwards its free energy usage. If you're sitting a static screen (e.thou., reading this commodity), power consumption is low. When your computer has gone idle (say, you've stepped abroad to eat dinner), the bill of fare will shut itself off, cartoon about 3W of ability to maintain its PCI-Due east connexion. When you get back to the PC, the card will spring back to life in a few milliseconds.

That's smashing, when you lot've got a single carte du jour in your machine. Just if you're using multiple cards bundled in CrossFire, the extraneous cards can plough themselves off completely when y'all're not gaming. The carte connected to your display stays alive , drawing as footling as 15W of power. The residual will punch down to aforementioned two − 3W, ready to leap to life once you need them.

Eyefinity 2.0: AMD'southward Eyefinity technology makes a return, and it too is improved. A refresher: Eyefinity is AMD's multi-display engineering, allowing you lot to drive multiple displays from a unmarried menu — the Radeon Hard disk 7970 tin support up to 6. This isn't new — we saw similarly capabilities from the dual-GPU $700 Radeon Hd 6990, or the Radeon HD 5870 Eyefinity vi Edition, which was built with that exact configuration in mind. Enhancements on the usability terminate comes from back up for custom resolutions, and improved bezel compensation, and so you tin can adjust the layout of your displays should you take a jumble of mixed-resolution monitors.

Also new: AMD'due south HD3D technology now supports Eyefinity. That makes the Radeon HD 7970 the the first single-GPU graphics card capable of driving three 3D displays. Nvidia has offered support for iii 3D displays with their 3D Vision Environs tech, just that requires at least two cards bundled in SLI, or the dual-GPU Nvidia GeForce GTX 590.

I've always had mixed feelings on Eyefinity, and that isn't nearly to change. AMD makes a few compelling arguments: ownership three 24-inch monitors (at about $200 apiece) is even so cheaper than buying a single thirty-inch brandish (at or above $1000). Just at that place's still the affair of desk-bound space, spending $600 on displays, and thick bezels sitting betwixt each display. Naturally, if cost, space, and bezels aren't an issue, more power (and pixels) to you.

Testing: Synthetic Benchmarks

We pitted the Radeon Hard disk 7970 ($550) against AMD'south previous single GPU champ, the Radeon HD 6970 ($250), and an EVGA GeForce GTX 580 Classified ($590), a 3GB variant of the GeForce GTDX 580. All tests were performed on an Intel Core i7-3960X CPU, equipped with 32GB of RAM and running on 64-bit Windows 7.

Unigine Sky

Let's get-go with Unigine Heaven. It'due south a rather forward-looking criterion built on a DirectX xi-based game engine that's currently in development. Information technology'south rather strenuous, packed with high detail levels, dynamic lighting and shadows, and lots of tessellation.

The results are pretty clear cutting. The Radeon HD 7970 maintains a heady pb at every resolution and quality setting, with the Radeon Hard disk drive 6970 sitting in final place.

3DMark 11

Next upward is Futuremark'due south 3DMark xi. This one'southward an industry standard, and churns through a number of graphics and CPU intensive tests. Information technology then assigns a score based on how the hardware performs. We were but interested in the GPU score, here.

More of the aforementioned here. The Radeon Hd 7970 maintains its pb, with a score that'due south 15% higher than the GeForce GTX 580 on the Operation setting, and 26% college on the Farthermost setting.

Crysis 2

The first of the "real" games we'll be testing is Crysis 2. In its heyday, the original Crysis brought the mightiest PCs to their knees. The game's engine and the engineering running it have improved substantially since then, simply Crysis 2 can still brand make the near stiff hardware sweat.

The Radeon Hard disk drive 7970 maintains its lead over the GTX 580, albeit only by a scattering of frames. That said, information technology'due south of import to go on in mind that 7970 is nigh $40 – $l cheaper than the menu we tested.

Dirt 3

Next up is Codemaster's Dirt 3. This rally racer couples fast paced action with lush visuals. It's a little less demanding than the balance of our testing lineup, but yet a demanding title, in its ain right.

At the 1920-by-1200 resolution with anti-aliasing cranked up, the Radeon HD 7970'south lead drops to a mere ii frames per second. At 2560-by-1600 it pulls ahead by 17 frames, but call up that anything over 30 frames per 2nd is considered playable, with 60 frames per second being something of a sweetness spot. You aren't going to notice much one time y'all've eclipsed the 100 frames per second mark, though it is a nod in the direction of future-proofing.

Metro 2033

Tertiary on our list is the post-apocalyptic showtime person shooter, Metro 2033.

This one proved to be the nearly daunting of the bunch, with the GeForce GTX 580 barely pulling away from the Radeon HD 6970, much less it's new, faster sibling.

Just Cause 2

And finally, Only Cause two. We're going with the "Concrete Jungle" examination, which is the most strenuous of benchmarks.

Starting to audio like a broken tape here, merely the results have been fairly consequent. The Radeon HD 7970 has maintained a consistent lead, outpacing the GeForce GTX 580 in every game we threw at information technology.

Value

We've seen how the cards stack up, operation wise. But is the Radeon HD 7970 a good value?

Well, yeah.

A good value at the high end, at to the lowest degree. To come with our Dollar per frames-per-2d metric, we compare the price of the card to the average results we saw in our testing. The $350 Radeon HD 6970 may ultimately lag behind the pack, simply its performance was in line with the lower price tag. At the high end, the Radeon Hard disk drive 7970 soundly trounces the $590 EVGA GeForce GTX 580 Classified. A standard GeForce GTX 580 would cost less, merely would ultimately compete fifty-fifty less favorably.

Power Consumption

This is where the Radeon Hard disk drive 7970 really shines. By shrinking downwards to the 28-nanometer process, AMD can lower the ability draw of their GPUs a scrap, without sacrificing performance.

That the 6970 uses the least corporeality of power under load isn't too surprising, as information technology is less powerful card. Merely accept a expect at those idle numbers. Our testbed isn't the most energy-friendly around, packing 3GB of RAM and the Sandy Bridge Extreme Edition processor. Ability measurements are taken straight from the wall, and factor in the entire machine. That 95W watts is impressive — in indicative of the work AMD has put into their ZeroCore tech.

Performance per Watt

Our terminal chart compares the power the menu drew while under load confronting the average frames per 2d it earned on our games tests. This volition give us an idea of a card'southward overall efficiency.

We're seeing the benefits of the die shrink directly here. The Radeon Hd 7970 does more while using less power at every resolution and setting we tested.

The World'south Fastest

The "world'due south fastest" unmarried-GPU graphics card title has inverse hands yet again. AMD'due south 7970 ousts the Nvidia GeForce GTX 580 by delivering better operation, drawing less power, and ultimately existence more cost-effective. And that was against an EVGA GeForce GTX 580 Classified, a souped of variant of the standard GTX 580.

Nvidia is certain to accept an answer to this card afterwards in the twelvemonth. Just equally certain as AMD is to have a more than modestly priced variant built on the new architecture, poised at taking on the Nvidia GeForce GTX 570. Yet things shake out, with Ivy Span coming down the pipe in just a few months, it's an exciting time to be a series upgrader.
