Sіnсе thе Mobility Radeon HD 5870 GPU іѕ ATI’s flagship mobile processor, іt іѕ currently thе performance king. Applications thаt υѕе ATI’s Stream technology wіƖƖ really see a performance boost οn thіѕ GPU!

Although it's been out for a few months now, Impulse Gamer finally got their gaming hands on this powerful single GPU graphics card, the ATI Radeon HD 5870. If you're a gamer, more specifically a serious gamer than this is the card for you which is Windows 7 ready and boasts DirectX 11 capabilities with some truly powerful and kickass specifications. It even has little hidden surprises hiding in this card such as DirectCompute which in laymen's terms allows the CPU processor be used by the operating system for not just games but other processing capabilities and some great connectivity options. 

Highlights

• 1GB GDDR5 memory
• ATI Eyefinity technology with support for up to six displays
• ATI Stream technology
• Designed for DirectCompute 5.0 and OpenCL
• Accelerated Video Transcoding (AVT)
• Compliant with DirectX 11 and earlier revisions
• Supports OpenGL 3.1
• ATI CrossFireX™ multi-GPU support for highly scalable performance
• ATI Avivo™ HD video and display technology
• Dynamic power management with ATI PowerPlay technology
• DL-DVI, DL-DVI, DisplayPort, HDMI
• PCI Express® 2.0 support

Still not convinced, what about the inclusion of EyeFinity and the ability to connect... let's see, SIX MONITORS! A-HA! That's right, crazy talk but with the 5870, it can do just that.

With 2.7 TFLOPS, this card will be rendering your gaming worlds without even breaking a sweat but best of all, the clarity of the picture quality (2560x1600) is unparalleled. But wait, there's more! Let's throw in 1024MB RAM and the ATI Radeon HD 5870 is one of the world's most powerful single GPU consumer graphics cards available.

What about price? Depending on store and brand, the card can be bought for as little as $500AUD if you look around for a good deal. However, before we get into the crux of this review and for the true techno junkies, let's see what the official specifications of the ATI Radeon HD 5870 is;

Process	40nm
Transistors	2.15B
Die Size	334nm2
Engine Clock	850Mhz
Shader Processors	1600
Compute Performances	2.72 TFLOPS
Texture Units	80
Texture Fillrate	68.0 GTexel/s
ROPs	32
Pixel Fillrate	27.2GPixels/s
Z/Stencil	108.8GSample/s
Memory Type	GDDR5
Memory Clock	1200Mhz
Memory Data Rate	4.8 Gbps
Memory Bandwidth	153.6GB/s
Maximum Board Power	188W
Idle Board Power	27W

As you can see, the 5870 is no slouch when it comes to performance but best of all, it manages to keep an acceptable board power of 188 watts and even more impressive, only 27 watts for idling. This is a huge difference compared to the HD 4870 and the end results definitely speak for itself. The only issue with the power consumption of the card is that it's a little loud when it's being pushed to the max. Unfortunately this is the price of high-end graphics cards but a decent case can muffle this noise.

Of course with the power, comes the price and also a physical size of 28cms with a rather heavy weight of almost 1kg so when installing this card, you need to be a tad careful not to drop it on your motherboard. However once installed, the card definitely matched the hype from AMD as we got ready for some fun and enjoyable testing.

In relation to hardware tessellation (which the card can do) or the new features of DirectX 11 such as HDR Texture compression (which also the card can do), I'm not going to bore you any more on specifications but basically, this card can really process graphical calculations when it comes to the crunch and what it means to the gamer is some extremely realistic and amazing graphics. This is what gaming is about and the features of this card will push developers in a variety of new ways, to wow the player. Want even more power, just connect two 5870's together via crossfire but just be warned that you need a power supply to handle it

The Test

After connecting the card to our motherboard, connecting the two power cables and installing the latest video card drivers, we were ready to unleash the beast. Our test system specifications are as follows;

Test Specifications

• Core i7 965
• ASUS X58 Motherboard
• ANTEC TruePower Quattro Power Supply 1200 watt
• 4095MB DDR Corsair Memory
• BenQ G2411HD LCD
• Logitech Gaming Keyboard
• Logitech G5 Laser Mouse
• Seagate Constellation
• OS - Windows 7 64-Bit Ultimate

On a FULL HD LCD, the video quality of Windows was very sharp with vibrant colours and easy to read text. Whether using Office, surfing the net or watching high definition Blu-ray discs, the card done these images justice. The first piece of software to test however was Futuremark's 3DMark Vantage which is one of the world's definitive benchmarking programs in terms of graphical processing and capabilities. The good aspect of this card is that it can manage to test the CPU and GPU separately or together.

The results for the 3DMark Vantage produced some very high results and even compared to its competitor, the 5870 produced some impressive scores with the GeForce GTX 295 still a tad ahead of AMD. But for the features of the card and the future of the gaming, our money is on the 5870.

Far Cry 2

One of the world's ambitious first person shooters is Far Cry 2, set in a variety of lush scenarios which really push our existing graphics cards. As players get involved in a civil war in Africa, they only have guns as their friends. The best part of Far Cry 2 is the realism as you control Jack Carver in this amazing virtual world with no monsters... just of the human kind. As you can see from results for Far Cry 2, the card done very well with high resolutions and considering that on high definition, the card scores 58 frames per second, that's extremely acceptable gaming in our books.

HD 4870 41 FPS

Over clocking

Of course for overclockers, the card can be over clocked and although we didn't push it too much (these cards have to sent back you know), we managed to get around 5 to 15% of additional grunt which is quite impressive. With appropriate cooling, I'm sure overclockers get even more from this card.

Conclusion

At the end of the day, this card has the power but unfortunately the world is not just ready for this card. In a few months time, when more games support the features and more specifically DirectX 11, this card will start to advance in performance and graphical capabilities. For a single GPU card, this is the king of the hill and the results speak for themselves.

Of course, with the ability of EyeFinity, connecting additional screens is child's play and with the dual-GPU version of this card around the corner, it just got good to be a gamer. Best of all is the price which is definitely bang for your dollar, highly recommended!
