AMD Radeon HD 4870 X2 technology preview @ Elite Bastards

Since its launch courtesy of the Radeon HD 4850 and 4870, AMD's latest RV770 graphics core has proved itself admirably at the price points at which has been sold. However, today sees the company looking to leverage these capabilities in the enthusiast sector, by teaming up two RV770 cores in a multi-GPU configuration. The result is the Radeon HD 4870 X2, and to accompany today's launch of this part we take a look at just what makes this particular offering what it is.

Sapphire HD 4870 X2 Review @ OCC

Most of the video cards I have looked at lately have a good bit of headroom for the enthusiast crowd. I was expecting the HD 4870X2 to offer that same level of overhead for overclocking. The HD 4870X2 gave up a little bit of love, but not as much as I had hoped for - 55MHz on the GPU cores and 50MHz on the GDDR5 memory. Both pretty low numbers when you consider that this video card is an enthusiast-level card. I suspect that heat is the main culprit in limiting the overclocking here. With temperatures in the range of 90+ degrees Celsius, heat is a major concern, and may ultimately be the problem to solve to get more overhead. At 955MHz on the memory, I ended up with large colored blotches on the screen. At 950MHz, the problem disappeared. On the GPU cores, once I got over 805MHz, I was greeted with lockups and reboots. Setting up a profile in the Catalyst Control Center and modifying the XML file for the profile did not help, as it has with the 4850 and 4870 video cards. The fan speed never changed, so I was left with a hot card and no way to cool it down any more than the drivers would allow; as with any piece of hardware, your mileage may vary. Knowing what my limits were on the clock speeds, I decided to see how much the CPU clock speed was impacting performance. So I pulled the Q9450 and put in my trusty QX9770 to get some real clock speed to find out what kind of performance difference the CPU makes. At 400x10, the performance did not let me down. In 3DMark06 at the default 1280x1024 resolution, the combo did not disappoint - 22520 was the score I achieved.

Neoseeker reviews the Palit HD 4870 X2

With the HD 4850, HD 4870, and now the HD 4870X2, ATI has achieved the equivalent of the Triple Crown of Thoroughbred Racing here. This line-up really throws a challenge towards NVIDIA, and bodes well for further competition between these two companies. The only drawback to this video card is at the moment, it offers perhaps too much raw GPU power for the game's of today to effectively handle. But of course, that is not really a drawback at all.

AMD's Radeon HD 4870 X2 graphics card

THIS SHOULD BE fairly painless. We've already previewed the Radeon HD 4870 X2 for you, and today that card is becoming official and available for purchase. To mark the occasion, we've wrangled not one but two of these dual-GPU monsters and paired them up via CrossFire. We've also assembled a killer's row of GeForce GTX cards for a comprehensive look at the next generation of multi-GPU madness. Can we set a new record for power draw at the wall socket? Oh, I think you know we can.

AMD Radeon HD 4870 X2 & X2 Crossfire

It's that time, AMD today unleashes their all new high-end product, the Radeon 4850 and 4870 X2. For those of you who lived under a rock and do not know what the X2 actually stands for, it's as simple as it sounds. X2 is times two .. these products are based on multiple GPUs per graphics card. In essence you take a large PCB (printed circuit board), position two 4850 or 4870 processors with an interconnect bridge-chip, grab a handful of memory chips, and then a pinch of resistors and mosfets. You put it in the pan, stir it and voilla ... your serving is ready. Wanna see how fast the fastest performing graphics card in the worlds is ? Of course you do ..

ATI Radeon HD 4870 X2 - AMD Back On Top @ HotHardware.com

The Radeon HD 4800 series didn't exactly overwhelm NVIDIA's GTX 200 series with raw performance. In fact, the GeForce GTX 280 and 9800 GX2 were more powerful than the Radeon HD 4870. The Radeon HD 4800 series cards, however, were still excellent cards and they were offered at extremely competitive prices, which put significant pressure on NVIDA. At the time of their launch, the Radeon HD 4850 and Radeon HD 4870 were both less expensive and more powerful than the GeForce 9800 GTX and GeForce GTX 260, respectively. Since then, NVIDIA has reacted with a quick round of price cuts.

While enthusiasts were contemplating the purchase of a new Radeon or GeForce, AMD then planted another seed and released some concrete details regarding the Radeon HD 4870 X2, as if to say, "Yeah, we've got you covered at the $300 price point and a new, ultra powerful behemoth is coming real soon too. Maybe you should hold onto your upgrade money for a bit?"

That behemoth is the Radeon HD 4870 X2 and it arrives today. As its name suggests, the card features two RV770 GPUs running in tandem, for what is effectively a Radeon HD 4870 CrossFire configuration on a single PCB. Other than its pair of GPUs, however, the Radeon HD 4870 X2 has a few more differentiating factors we're now able to tell you about. Read on for the full scoop...

Sapphire Radeon HD 4870 X2 in Crossfire

It’s hard to turn around and say that the HD 4870 X2 is one of the most anticipated cards of recent times, due to the plain fact that there have been so many cards released over the last three months. While some had thought that the new HD 4870 would become the fastest single card solution on the market, the price AMD launched the card at gave indication that the chances were going to be pretty slim.
