ATI Radeon HD 4850 and 4870: RV770 has arrived

Topic:

Hot Hardware looks at the new ATI Radeon HD 4850 and 4870.

Quote: "Last week, due to some unexpected circumstances, we were able to post a sneak peek of the RV770 GPU and ATI Radeon HD 4850 graphics card. As our limited testing showed, the Radeon HD 4850 was quite promising for a $199 graphics card. But we weren't able to tell the complete story. While the initial benchmarks definitely looked good, there was a lot more to talk about in regard to the Radeon HD 4850 and the RV770 GPU at the heart of the card. Read more

Diamond ATI Radeon HD 4850 Review

Topic:

Motherboards published a Diamond ATI Radeon HD 4850 review. Diamond just announced the HD 4850 Card last Friday.

Quote from the review: "This card will essentially be a XFX Black Edition 9800GTX as the clock speeds will be 738MHz for the core and higher clock speed for the Shader clock. It will be an interesting battle for sure, but ATI has fired the first salvo towards high-performance sub-$200 video cards of 2008. The high-end enthusiast market wanting an ATI card that competes well against NVIDIA's best will have to wait a month or so until the HD4870 arrives and its dual-chip brother the 4870X2. They will have higher clock speeds, GDDR5 memory and be much more competitive against the GTX260 and GTX280 (here's a hint; two 4870s working together on a single PCB will likely outperform GTX280 for the same price point) If this forces NVIDIA to lower their prices it will be a much better market, after all, who wants to spend $650+ on a new video card if you can help it.

A first look at the ATI Radeon HD 4850

Topic:

TechReport offers a first look at the unreleased ATI Radeon HD 4850.

Quote: "The battle between AMD and Nvidia for the hearts, minds, and disposable income of PC enthusiasts is starting to get scrappy. First, AMD scheduled a press event to distract folks from Nvidia's GeForce GTX 200 series launch, which Nvidia subsequently pulled forward. Perhaps in retaliation, the green team then divulged plans to unleash a faster version of its GeForce 9800 GTX. This GeForce 9800 GTX+ will sell for only $229, dropping the vanilla 9800 to $199—conveniently stepping on the price point of AMD's next-gen Radeon HD 4850 graphics card. Read more

TheTechLounge published a Sapphire Radeon HD 3870 X2 review.

Quote from the review: "So why not just get two 3870s and rub a little CrossFire into your box? There are two reasons, really. For most people, that's just not an option. Dual-PCI-Express can easily tag a Benjamin onto the price of a motherboard, and, in Micro-ATX land, it's a mythical beast that visits overclockers in their dreams. Read more

Diamond Viper Radeon HD 3650 1GB review

Topic:

Techspot published a Diamond Viper Radeon HD 3650 1GB review.

Quote from the review: "The Radeon HD 3650 looks to be an attractive product on paper, it is the latest member of the Radeon HD 3000 series, and can carry up to 1GB of memory on-board. The 3650 is also a Direct X 10.1 compliant card that supports the PCI Express 2.0 bus.

AMD announces GDDR5 ATI Radeon Graphics Cards

Topic:

Today AMD announced the first commercial implementation of GDDR5 (Graphics Double Data Rate, version 5) memory in its forthcoming next generation of ATI Radeon graphics cards.

The GPU performance in today's graphics cards is limited by the rate at which data can be moved on and off the graphics chip, which in turn is limited by the memory interface width and die size.
The higher data rates supported by GDDR5 is up to 5x that of GDDR3 and 4x that of GDDR4. Read more
