GPU NEWS Channel

[comp@ddict]

This is one of the two dedicated NEWS Channels that have been created after much request by many!

And I think I don't have to say anything else to it.
MOD EDIT:

Post all those zillions of gossips you find in the internet not in seperate threads but here. It becomes hard to manage a hell lot of news items which may or may not be true or which may not be significant enough for threads.

This thread has been stuck for a reason: To avoid clutter in tech news section.
=====================================================================================

Radeon 4730 is 55nm RV770LE

PowerColor was the first to inform the world that Radeon 4730 is coming and as the name implies, many expected a 40nm RV740 rather than RV770LE 55nm.

ATI used Nvidia renaming strategy (shame on you) as this is nothing more than Radeon 4830 renamed to justifiy its lower price. This is not a simple SKU rename as Radeon 4730 name implies that the card is different since it has 700MHz clock versus 575MHz on 4830, and 128 bit memory interface powered with 3600MHz GDDR5 memory.

???

I thought it would be 40nm. if it is 55nm, then it would go down the gutter without any sale just like HD4830.

Re: nVidia/ATi NEWS Channel

^^ It's the HD4830 chips with GDDR5 and 128-bit, but the performance will be almost equal to HD4770 as this chip as 956million transistors.

Re: nVidia/ATi NEWS Channel

I think this is clever.

GDDR5 is becoming cheaper by day and has several advantages over GDDR3.

Halving the memory bandwidth helps cut down costs to manufacture GPU.

This can be used to include more GDDR5 because its only slightly more expensive, and there is a load of old 512MB GDDR5 modules lying around since newer high end GPUs need 1GB atleast.

Re: nVidia/ATi NEWS Channel

I think GDDR5 already costs almost as much as a good 0.8ns GDDR3 memory. And with 128-bit, the cost comes out to be very very low, instead of a 256-bit GDDR3.

And I think the HD4730 might just be faster than the HD4830 and the HD4850, remember, a 700MHz HD4830 beat a HD4850 hands-down!

Yup. But this could indeed also be a way to get rid of early 512MB GDDR5 ram modules.

And I think the HD4730 might just be faster than the HD4830 and the HD4850, remember, a 700MHz HD4830 beat a HD4850 hands-down!

But it would have very little overclocking headroom considering the fact that it normally doesn't go much higher. It would be heavily sought after by OEMs I guess.

Re: nVidia/ATi NEWS Channel

Offtopic:
I suggested this a couple of times. But then some members said, "A news is a news"...

Re: nVidia/ATi NEWS Channel

LOLz
But don't forget, it's not mine thread, this is public. It's for all of us to share and discuss news here.

hey guys dont consider me mega noob but i have less info for graphics card...
what are nvidia and ati? what is geforce?

Re: nVidia/ATi NEWS Channel

G300 taped out - GTX350?

Transistors - 2.3 Billion
Shader Units - 512
Processing Power - 2457 GigaFlops

Memory Interface - 512-bit
Memory Amount - 1/2GB
Memory Type - GDDR5
Estd. Bandwidth - 281.6 GB/s

Core - 700Mhz
Shader - 1600MHz
Memory - 1100MHz

API - DirectX 11
- OpenGL 3.0
- OpenCL

These are the first impressions on the next generation high-end hardware from nVidia. And boy, it looks like this single-card would beat a GTX295 by 50%

Re: nVidia/ATi NEWS Channel

^^Hell Yeah. This is only GTX350 ? Then we can expect 360, 370, 380, 390, etc too. Imagine how would they be.

OpenCL and OpenGL 3.0 support is SWEET. DirectX 11 isn't that great since there are no games.

I hope ATI HD5870 manages something to beat this beast.

No, this is for the UBER-HIGH end card aka replacement for GTX295. This is to compete with the HD5870 X2.

Re: nVidia/ATi NEWS Channel

And is it a multi-GPU solution ?

I can't wait to get hold of one of ATI's mid/value-range cards from HD5000 series. I heard the HD5650 or HD5670 should perform at par with HD4850 or atleast HD4770 AND support OpenCL, OpenGL 3.0, DirectX 11 AND come quite close to the 1TFlop mark and consume less power being 40nm and most importantly, be priced around 110$ or Rs. 6000.

Re: nVidia/ATi NEWS Channel

Looks like ATI wanted to test the market with HD4770 and this is the reason why they released tiny amount of these cards to the market.

Another reason is that TSMC is getting pwned with their 40nm process. Need to refine it further before starting to ship zillions of chips. This will affect both AMD and nVidia launch dates.

This means only one thing. Once AMD sets up Global Foundries, Inc. to start manufacturing its CPUs and GPUs (100% of its CPUs, 66% of its GPUs) AMD will have a distinct advantage over nVidia.

And since AMD will no more have to bother about switching fabs too fast and ending up making R&D losses, AMD can keep up with intel as far as CPU manufacturing processes is concerned.
