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.

[comp@ddict]

^^ 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.

[MetalheadGautham]

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.

[comp@ddict]

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.

atlast all compaddict threads in one... uhhhhhhh... relief...

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

[comp@ddict]

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.

[swordfish]

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

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%

[MetalheadGautham]

^^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.

[comp@ddict]

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

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

[MetalheadGautham]

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.

[desiibond]

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.

[desiibond]

Well said sir

[j1n M@tt]

reason y no Palit HD4770 and no other new cards from Gainward : xbit news


P.S. : the source was actually pointed out to me by dominator from this forum

Gainward is switching to only nVidia.
Palit/Gainward is pissed off at ATI thinking that its punishing it by not giving new chips for making custom boards, to protect interest of larger partners like Sapphire.

But fact remains, ATI is having a hard time getting the 40nm process up and running. So they are sending the *few* RV740 chips produced to their large partners like Sapphire.

[j1n M@tt]

^^ya dats the real truth I think, they are only producing few RV740 chips.

[desiibond]

I do hope that Palit sticks to AMD. It's ATI that is giving lot of sales for Palit, esp. the 4xxx series cards. If AMD kicks out Palit, it will be a lose-lose situation.

[j1n M@tt]

AMD always sux in marketing strategy. Nvidia and Intel always gains over AMD not only b'coz of technology, Nvidia's and Intel's marketing is wat makes them get standout in market share, no matter wat their pricing for products is, they still hav customers.

AMD DX 11 GPU IN OCTOBER

Associates explain, that first video chip AMD with directX 11 support will appear during October 2009. In this time, the operating system Windows 7 will be presented, and even the consumer demand will grow . AMD is also ready to begin the production of its video chip new generation, but technological problems interfere with it. Company waits, when TSMC problems with 40 nm technical process will be removed.

HD5800 coming guys!!!!!!!!!!!

[desiibond]

coool. And the war enters new level in October

DX11
40nm
1GHz clock

Interesting
very interesting.

[comp@ddict]

Right now HD5870 will be having 900 or 950MHz core. But 'm sure AIBs will come out with 1GHz and + variants.

[MetalheadGautham]

Does it support OpenGL 3.1 and future OpenGL 3.2 ? Does it support OpenCL ?

I want the above two support in a mid range GPU since I will be taking up Computer Science Engineering in collage and I am interested in messing with OpenCL C++ libraries.

Nvidia Tegra Promises 1080p Video, 25-day Music

Many of our mobile internet devices (MIDs) today are relatively underpowered. Given that the small devices are usually designed only for simple uses, they’re often of modest computational muscle. But Nvidia plans to shake things up with its Tegra chip technology.

A dozen new MIDs debuted at Computex today using Tegra, except that they weren’t quite the devices we expecting to get the Tegra-treatment. All of the Tegra-based devices were either netbooks or tablet when really, we're waiting for the technology to find its way to a PMP or cell phone.

Nvidia describes Tegra as a computer-on-a-chip with what it calls a “heterogeneous multiprocessor architecture.” A CPU runs the html and Java, an HD video processor that makes streaming HD video playback possible, and a GPU for a compelling user interface and for Flash acceleration.

Perhaps the biggest attraction of the Tegra is its computation power in relation to power draw. Nvidia advertised that Tegra devices are capable of:

Listening to music for 25 days straight on one charge
Watching 1080p HD video for up to 10 hours
Playing video games at 46 frames per second

We’re impressed at the audio and music playback claims, but the variance in games makes us a little unsure about that 46 FPS claim.

At Computex are the following models already on display:

Compal Communications, Inc. CN88 (netbook)
ICD Ultra (tablet)
Inventec Applications Corp. Rainbow (netbook)
Mobinnova Mabo (tablet)
Mobinnova ViewBook N910 (netbook)
Pegatron Vivid (netbook)
Wistron M5 (netbook)
