ATI Radeon HD 4830 Comes in October
The card is built on the RV770 chip and features less pipelines than 4850

There is little time left until we see the new Radeon HD 4830 card on display, as ATI seems determined to have it released at the beginning of October. The
new card is built on the well known RV770 chip and comes with a 256-bit memory interface. Voices over the web say that the new graphics card will actually be made by AIBs themselves, which means that we're going to witness the launch of differently clocked boards and probably also differently featured.

The RV770LE graphics card will come with 512MB of memory and will have 480 stream processors. Sources say that the card will differ from the Radeon HD 4850 solution on the pipeline numbers, as the graphics card manufacturer plans to lower the pipeline count on it. There are no specific details on the amount of branches that will be cut, yet the card will end up with less pipes than Radeon 4850 and 4870.

When it comes to pricing, the card should fit just well on a position below Radeon HD 4850 and above HD 4670, but the company hasn't come up with a specific price just yet. We should also note the fact that Radeon HD 4830 is expected to fight the NVIDIA GeForce 9800GT and GeForce 9600GT cards, and the 9800GT's are placed a little over €100 ($150).

AMD still plays silent when it comes to its future products, feeding us only small pieces of information from time to time. Even so, other small pieces manage to leak to the Web. The guys from VR-Zone published on their site a a small slide which lists the Radeon 4830 card besides the 4850 and 4870, showing at the same time the ASIC variant of each graphics solution. As the launch date nears, enthusiasts with low budgets won't have too much to wait to see what this card can do.

Radeon 4850 X2 still on hold

No date known

ATI was supposed to release its Radeon HD 4850 X2 a card with DDR3 memory and two RV770 chips, but so far there is no direct conclusive order to do so.


This card was supposed to show its face in September and we asked around and it doesn’t look like you will see any of these cards by the end of this month. It is not that we have a lot of September left, as AMD would have only eight days to ship these cards in the current month.

Radeon HD 4870 X2 is obviously selling well and this 2GB DDR5 card is not in any kind of shortage; and ATI probably tactically delayed the slower part with DDR3 memory as it simply doesn't have to sell it today.

We will keep our eyes opened for this interesting card.

ATI's RV870 Goes 40nm, RV970 Comes in 2010
RV870 is said to bring a GPU process smaller than the CPU one for the first time in history

ATI started the 55 nanometer series with the RV670, continued with RV770, and both chips marked success. Rumors say that the company plans to move the fabrication process directly to 40nm with its next generation chip codenamed RV870. All of us would have expected the die to shrink to 45nm, but it seems that we will see graphics processor manufacturing
technology smaller than that of CPU's for the first time in history. Intel uses the 45nm for its CPUs, AMD will do the same by the end of the year, and there are little chances to see that die going smaller too soon.

ATI's RV870 will come with more transistors and with boosted clock speeds, but there are no specific details on the actual architecture of the chip. The new GPU is expected to arrive in 2009, and some even say that it might arrive before one year passes from the RV770's debut. Since the 40nm process could prove to be a tricky one, it is too early to get a fixed date for the chip's arrival.

The 2009/2010 time frame announces itself to be a fruitful one when it comes to the graphics IT industry. Beside the RV870 chip from ATI, 2009 is also likely to bring to us Intel's Larrabee 'visual computing' technology. The company has already announced its plans to launch Larrabee sometime at the end of the next year, or the beginning of 2010. There are a lot of suppositions spinning around Intel's multi-core graphics processor, since it has been stated by the company that it is supposed to differ from what we know graphics cards to be.

Intel said that Larrabee would also support games and video applications like any other card, but that it is actually intended for programming. Still, the company has a lot of work to do on the drivers' part, even if the hardware comes up right. There are many games that require the driver support to work smoothly; otherwise, end-users won't come near Larrabee.

On the other hand, 2010 is rumored to bring to the market some other new cards from Nvidia and ATI as well. The green company is expected to launch its GeForce 11 graphics cards series, and some say that we might see even two series launched during that time. As for ATI, the RV970 generation of GPUs is rumored to come during 2010.

[vr-zone] Radeon HD 4830 Has 640SP, Launch On Oct 21st

Seems like Radeon HD 4830 will have 640 stream processors instead of the 480 as we learned previously. It comes with 256-bit memory interface with 512MB GDDR3 memories. Since AIB partners are free to design their own cards therefore we should be seeing different card solutions with different clocks and memory sizes/types from each makers. The launch for Radeon HD 4830 is set at October 21st and it is targeted primarily at Nvidia GeForce 9800 GT with a less than US$150 price tag.
