Radeon 4850 scores 5000 in 3Dmark Vantage

The 9800 GTX scores about 5003 in 3Dmark vantage, so while the HD 4850 scores just above 5000, ATI's flagship card, the HD 4870 will follow the 4850 with even higher scores.

I like AMD and believe they offer good value products, however it should be born in mind that previous generation of cards seem to perform significantly better in 3DMark then in real world situations.

But I do hope 'this time if different'.

I am looking at the lower end 4870 (GDDR3) as a possible upgrade for my aging x1900gt.

Lets hope for competitions sake AMD really do compete again.

But they plan to use GDDR5 in the 4870, all I have to say is, holy crap, they just skipped GDDR4, haha. That will haul some memory bandwidth.

I was under the impression they were doing 2 versions of the 4870, one with GDDR3 and one with GDDR5

from what I've seen so far, it's only GDDR5.

No he is correct there will be one with DDR3 and one with DDR5. From what I read anyway. This below is taken from a PC website talking about the different versions. Site also states that the new cards support GDDR 3, 4, 5 so any third party maker could slap GDDR 4 on a card if they wanted to do so.

The Radeon 4850 will debut with a GPU clocked at 650 MHz, while the shader array will be clocked 850 MHz. The 4870 has an 850 MHz core and a 1050 MHz shader clock. The fill-rate is closely tied to the GPU clock: The 4850 sports a fill-rate of 20.8 GTexel/s (32 TMU x 0.65 GHz), while the 4870 achieves a 27.2 GTexel/s (32 TMU x 0.85 GHz) performance.

The RV770 GPU is equipped with a 256-bit memory controller (512-bit for the Radeon 4870 X2: The R700 represents just two RV770 GPUs slapped together). 4850 GDDR3 models will come with 256 MB or 512MB of GDDR3 memory, clocked at 1.14 GHz (2.29 GTransfer/s), resulting in a memory bandwidth of 73.2 GB/s. 4850 GDDR5 versions integrate 512 MB of GDDR5 memory clocked at 1.73 GHz (3.46 GT/s), supporting a bandwidth of 110.5 GB/s. 4870 GDDR5 models will get 1 GB of memory clocked at 1.94 GHz (3.87 GT/s), achieving a maximum bandwidth of 123.8 GB/s.

Flagship dual-GPU 4870 X2 cards will include 2048 MB of GDDR5 memory clocked at 1.73 GHz. The Radeon HD 4870 X2 will be introduced at a later date (and could see spec revisions).
