HIS Radeon HD 4870 CrossFire Video Card Review - GDDR5 Arrives

 

Last week, AMD was forced to release the ATI Radeon HD 4850 graphics cards early since some retailers had already started selling the card to the public before it was launched. This week AMD has released the the Radeon HD 4870, which is priced at $299. This is the big brother to the Radeon HD 4850 and features higher clock speeds and newer cutting edge technology like GDDR5 memory ICs for improved memory bandwidth.

 

Quote:

 

"The Radeon HD 4870 is the first retail graphics card to use GDDR5 memory and the 512MB of memory uses Qimonda branded ICs. GDDR5 introduces features and functions that go beyond previous GDDR standards and enables GDDR5 to operate at data rates up to 6 Gbps, three times the performance of todays high speed GDDR3. The memory ICs feature adaptive power management, error compensation, adaptive interface timings and date eye optimization. The ICs being used are part number IDGV1G-05A1F1C-40X, which are entry level GDDR5 chips and are rated for just 4 Gbps. ATI has them clocked at just 3.6 Gbps, so these should have some overclocking head room left in them..."

"The ATI Radeon HD 4870 and Radeon 4850 are basically the same thing as both have the same number of transistors (965 million) and use the 55nm manufacturing process at TSMC. Both offer DX10.1 and Shader Model 4.1 support and use ATI's CrossFireX multi-GPU technology. The only big difference here is the clock speed and the memory type! The new higher clock frequencies mean the math processing rate is now 1.2 TeraFLOPS over the 1.0 TeraFLOPS found on the Radeon HD 4850..."
