Slides Reveal Radeon HD 4830 to be Tougher than Expected

Performance projections for the upcoming Radeon HD 4830, made news yesterday, where it is projected to outperform the GeForce 9800 GT. Two new slides published by VR-Zone shed light on how the RV770LE graphics processor manages to do that, and there's a surprise: It was earlier known that the RV770LE comes equipped with 480 stream processors, and one of the earliest reports even suggested that it could have a narrower 192-bit memory bus. The slides published, show that the new GPU could carry as many as 640 stream processors, double that of the RV670. It comes with a proper 256-bit wide GDDR3 memory bus. Also included, is hardware support for 24x custom filter anti-aliasing (CFAA).

It is also known that the new card is gearing up for an October 21 launch and would be priced below US $150. AIBs would be able to sell custom designed cards right upon launch. While the new GPU does look "tougher" and more equipped than expected, here's something to ponder: with twice the amount of stream processors as the Radeon HD 3870, as projections suggest, is it going to be only 10% faster than the 9800 GT?

Is this off-topic or is it just in the wrong place?

I mean that's a fact, everybody would agree, but I don't get why it's here. :confused:

it also says "AMD confidential" which generally means "if you give this out to the public, we will kick your ass"

i agree with most of your comments about the prices but a question keeps popping in my head... where the .... will the 4830 place pricewise in the market! please get back on topic

Musselsjust because you dont, doesnt mean the rest of the world doesnt. i use an OC'd 8800GT/GTX on a 40" HDTV with a native res of 1360x768. I also know many, many uni students with 15-19" LCD's (widescreen and not) because they cannot afford the cost, or the physical desk space for a larger screen.

making assumptions based on your own personal feelings tends to lead to illogical thinking.
I completely agree here - even those of us just content enough with our curent monitor.

Personally, my 19" 16:10 has been great, and continues to. I've looked at some larger monitors here and there, and haven't seen anything *decent* with a nice price tag on it just yet. The units that have the great color balance and contrast, the super-fast response times, etc, are still too expensive for my tastes - sure, I could've spent the money on a new screen by now over my last 3 GPU upgrades (went from 2 1950 PROs to 2 HD3870s to 2 HD4870s) . . . besides, I'd have a hard time fitting anything bigger than a 22" on my desk.

But, I'll keep up with the hardware - I'd rather my games move smooth as silk as much as possible . . . instead of sitting 2 feet away from a massive 24"+ screen. The bigger the screen, the further back one should be for best viewing, and for your eye health.




OT - I'd expect the 4830, per US market, to be about $50-$70 cheaper than the 4850. They might come in a little overpriced, but after a few weeks they'll settle in. I'd also expect the price of the 4850s and 4870s to drop a little as well.

To add another Point, Ive had this NEC Multisync LCD 1700V since about 2001, so its a 7YO Monitor and it seems the Picture has been about the same since it was Brand New.

Divide the amount of stream processors in ATI's cards by five to get the "real" amount. It'll make more sense then. ATI uses a funny way of calculating their stream processors -- thought everyone knew that? :p

The equation still remains. RV770LE has 2x the number of shader units as RV670.

The SPs in RV770 are simpler than the ones in RV670. At least from a manufacturing point of view. And although they would try saying it's the same, if you take something out, you will lose something, even if it's little. The word that thay used, according to a very technofreak article I saw, was "optimization". And although that word should mean "doing the same with less", ultimately in real world that means "using much less to do a bit less".

True -- I was just explaining why the performance is only 10-15% faster than a 9800GT even though it looks like it should be loads faster.
