AMD releases higher-end Radeon HD 4870

By on June 25, 2008, 11:01 AM
We saw the first wave of Radeon cards in the HD 4800 series hit store shelves last week, with the initial benchmarks showing the 4850 as a quite promising product for its suggested retail price of just $199. But there’s more coming from ATI and so now we shift our focus to the higher-end 4870, which has officially arrived today priced at $299.

Based on the same RV770 chip that powers the 4850, the new card is clocked higher at 750MHz and is the first to use newer GDDR5 memory technology that nets about 3.6 gigabits per second of headroom for its 800 stream processing cores. Besides clock speeds and memory type, the Radeon HD 4870 and HD 4850 are basically the same thing as both have the same number of transistors (956 million), use a 55nm manufacturing process, offer DX10.1 and Shader Model 4.1 support, and use ATI’s CrossFireX multi-GPU technology.

Benchmarks are already floating around the web, showing the Radeon HD 4870 is definitely a step up from Nvidia’s GeForce 9800 GTX+ and actually competes closely with the more expensive GeForce GTX 260, a $399 card based on a chip twice the size. Check out some reviews at Tech Report, HotHardware, AnandTech, and TweakTown.

YAY! GO ATI! I might upgrade to one of their cards if they keep this going!what I am afraid of is the life of the product.. the only card i've had before my 8800GTS is a radeon 9250 and it failed all the time.. shut down my computer,also friend had a problem with 9800Pro... games got stuck and restart required.. i dont know if its just me but thats why im afraid of getting near ATI

Hmmm I'm concerned myself...my 9800pro died on me too. I hear the 4850/4870 cards run pretty hot...but damn they have a nice price point than the new Nvidia cards.

@Nirkon:I can confirm the problems with the ATi 9800 Pro.Be aware of what the Reviews say about the Power Consumption / Temperature (in som cases) of the newer ATi's. Their Noise level looks very low though, according to the Anand Tech Link.I had one manufacured by PowerColor, which I'd had a 9600 Pro Before upgrading to a 9800 Pro.I could ONLY get the thing to work at half the AGP Bus Speed (x4) instead of the default x8. Which meant games would hang, reguardless of Platform Linux or Windows, unless I set it down to x4 in the BIOS.It could well have been the GPU's fabrication was not half up to par because my Brothers Sapphire works to this day, but I'd previously used the 9000, 9100 and the 9600 Pro's with no issues - which made me a little off put. I still managed to get good Frame Rates even with it at x4 AGP.
