AMD ATI Radeon HD 4800-Series Launches

Having had nVidia's latest graphics card launch within the last week or so, it was almost inevitable that AMD would want to show its hand. Enter the AMD ATI Radeon HD 4800-series, which, aside from still having a stupidly long name, marks AMD's attempt to offer some competition to the GeForce GTX 200 range.

The only card announced officially is the RV770-based, single slot, Radeon HD 4850. The same card Gigabyte leaked at Computex recently. 800 stream processors, a core clock of 625MHz and 1.99GHz (effective) GDDR3 memory on a 256-bit interface make up the vital statistics. On paper that's 50 per cent more stream processors than the Radeon HD 3850 and Radeon HD 3870 but at a slightly lower clock speed. The architecture itself has also been improved which should compensate for the reduction in clocks.

Apparently (but unofficially for now) the 4870 will offer a faster 750MHz core clock and use GDDR5 memory which should be impressive. About a month later on an 'X2' version will apparently also be coming which will, oddly enough, be the flagship card of the range. The main advantage AMD has is that using a 55nm manufacturing process allows the production costs of the 4800-series to be considerably lower than that of the - which in turn means the cards are vastly cheaper. We're told to expect the 4850 to retail in the £130-150 region, half the price of the GeForce GTX 260 with which it will likely compete.

The benchmarks I've seen tend to show the 4850 competing with the 8800GT & 8800GTS in most games - if anything slightly behind them. The GTX 260 should easily out perform the 4850. It will be interesting to see what difference GDDR5 makes to the performance of the 4870 though.

All the information I've read points to the 4850 competing with the 9800 GTX, not the 8800s.

ATI Radeon HD 4850

Nvidia GeForce GTX 280

Nvidia GeForce 9800 GTX

Nvidia GeForce 8800 Ultra

It seems obvious to me that the STUPIDITY in nomenclature has undoubtedly lied in Nvidia's court for the past year or 2 or 3 or 4. Not to mention the naming of different cards/GPU's with the same numerical ID. What's up with that.

I agree that the comparison/competition was not intended for the Nvidia GeForce GTX 200 series. Although the performance charts indicate that they indeed do have and will likely(4870 & 4870X2) have similar performance to that series. The comparison was intended for cards at their respected price range whatever that may be.

I find the ATI HD 4800 to be un-reliable in my new games. I tried it on the simplest online games I could find and it failed. I tried it in my older games and it failed. Its a piece of garbage Im never buying from AMD again.
