[tcMag] Radeon HD 4850 & 4870 in pretty pixels

As previously predicted the journey towards a 'full disclosure' of the Radeon HD 4800 series cards would be made through baby steps and the latest to be taken sees the Radeon HD 4850 and 4870 leaked in press photo form. Available for staring just below, the first two 4000 series cards will be powered by the RV770 chip which is built using the 55nm process and offers 480 Stream Processors. both cards will feature a 256-bit memory interface PCI-Express 2.0 support, CrossFireX, Unified Video Decoder (UVD) 2 and DirectX 10.1.

The Radeon HD 4850 will be equipped with 512MB of GDDR3 memory and is said to cost in the realm of $229 to $249.



The Radeon HD 4870 will signal the 'proper' return of AMD/ATI to the high-end segment as this card will utilize one RV770 chip paired up with 1024 MB of GDDR5 memory. The HD 4870's price tag will hover around the $329 to $349 zone. Both Radeon HD 4800 cards are said to be ready for a mid-June release but the Radeon HD 4870 will apparently become available in July.

I'm going to get 2 of the 4870's...

i am moving to ATI for the next gen cards. Nvidia has pissed me off with releasing 7 cards with exactly the same hardware inside and giving them different names.

ATI did it right. They knew that when G80 came out, their cards wouldn't be able to keep up. So they hit the drawing boards, and came up with something that will be at the top of the market. it took the learning of the HD 2 and 3 series to get there, but now its here... and now is the time to get these cards...

all thats left is to see how these preform with the new 280 GTX cards from Nvidia, which again, is still the same arch, but with tons more transistors and shaders...
good enough

HD4870 looks really nice with the stock cooler. I'm not happy with Nvidia at all. I mean their products are fine but their attitude annoys me.

The one part that gets me real excited is...

I hope this is true. Although I don't intend on buying Nvidia after the crap they pulled with Assassin's Creed, and the ridiculous power consumption of their new cards.

What makes you think RV770 isn't the same architecture? Both ATi and nVidia are just feeding steroids to shrunk R600 and G80. They both went back to the drawing boards to figure out how to stick more shaders to the same damn chips. We as consumers have no choice but to see who makes the better card then buy it.

After all I have no idea why people scold the 9-series so much. ATi did the exact same thing from HD2000-series to HD3000-series. Love it or hate it, both companies are marketing whores. If you want a true brand new architecture then get a S3.

ATI's new top end card is probably gonna be 1/2 the price of Nvidia's new 280.

Difference is, ATI had to, and didn't make as many cards from the one core, they made the 2900XT, then the HD3870 which was shrunk, then stuck two on the one PCB, Whereas nVidia got 8800GTX, Shrunk it into G92, made a couple new cards, then made a new series, which was just those previous cards, overclocked, then put two on the one PCIe slot, and called it a new series.

At least the HD3xx0 series had some improvements over the HD2xx0 series (Less heat, Power usage, etc)

And nVidia are just going "BIGGER IS BETTER!" and adding stuff, ATI are going "Ok, Here's our biggest weakness, lets pump that up first..."

Thing that will cripple the 4870 though is the 256 bit bus..., whereas the GTX280 has a 512 bit bus...although at almost half the price, it looks like it will almost perform the same telling from the spec sheets we've been seeing...
