@ desiibond - thanks for the review


@ MetalheadGautham - 64 bit GDDR5 may perform same as 128 bit GDDR3. I don't think gfx card manufacturers will use DDR3 as GDDR3 or GDDR5 64 bit replacement. Coz DDR3 has more latency as compared to both GDDR3 & GDDR5. What you may see is manufacturers may use DDR3 as DDR2 replacement on dirt cheap gfx cards.


@ comp@ddict - yup, ATI may use either 64 bit GDDR5 or 128 bit GDDR3 as both performs naerly same & the production cost is also nearly same.

[comp@ddict]

If GDDR5 becomes mainstream, tat might get cheaper than 128-bit GDDR3

[topgear]

^^ Yup, that should be...lets wait & see what will happen next

World first Radeon HD 4750 pictured

This HD4750 adopts non-reference PCB and features AC cooler instead of older cooler.Compared to HD4770,it has lower frequency due to low heat dissipation of 40nm RV740.In terms of cooler,aluminum heatsink and large-size silent fan with low speed can meet cooling demand.

[comp@ddict]

The price is a freaking 80$ awesome!

[MetalheadGautham]

The price is a freaking 80$ awesome!

Unfortunately that 80$ won't become Rs. 4000

[comp@ddict]

Yes, it wud end up at 5-5.2k hate these stupid duties.

[MetalheadGautham]

Yes, it wud end up at 5-5.2k hate these stupid duties.

nope. minimum 5.5k.

[comp@ddict]

But still, it's only 20Mhz slower than HD4770, hardly any difference. And doesn't require a power connector. It will become the new budget king(short lived)

Yeah. It could fill the void till HD5650 arrives.

Does it support OpenCL ?

Sorry for asking, but whats so special in it? BTW, Windows 7 has DX 11, so should I wait for DX 11 or should I purchase 4770 ?

Thnx in advance

[comp@ddict]

Wait for DX11, it's coming September 10

[MetalheadGautham]

Wait for DX11, it's coming September 10

I just want the following support:

1. OpenGL 3.3
2. OpenCL
3. OpenAL

I don't give a damn about DirectX 11.

And yeah, I also need

1. Price under 5K
2. High Power Efficiency
3. 1GB framebuffer (for 3D)
4. 1080p Crysis 0xAA @ FPS>45

[comp@ddict]

Well, the new Catalyst 9.8 supports some of what you need.

And 1GB under 5k plus performance is highly unlikely.

[desiibond]

maybe in half year, that could be highly likely

[comp@ddict]

I'm hoping the 800 shader or 960 Shader DX11 40nm cards(not 1200 high end) are cheaper, as

HD58xx series will be priced 249$ and up. 960 Shaders hopefully 175$ or so.

[desiibond]

anyways, just less than a month of waiting and we will know who is going to take the dx11 crown.

ATI Catalyst 9.8 is out

Without much of a buzz except past leaks suggesting that the company would roll out a beta at this year's Quakecon, AMD released the ATI Catalyst 9.8 WHQL driver suite to readers of the company blog, before formally announcing it and adding it to the AMD Game portal. The package installs drivers for ATI Radeon graphics hardware, including its discrete and integrated graphics processors, AMD 7-series chipsets, and ATI Theater series multimedia products.

With lack of proper documentation (read: release notes) at hand, there are no specifics available about the driver, though one could expect the usual application/hardware/OS-specific enhancement, a possibly expanded supported products list with new SKUs in the Radeon HD 4700/4800 series that surfaced over the last month.

[comp@ddict]

NExt will be Catalyst 9.9, with DX11 support!!! OMG it's coming!

[x3060]

but then will 4670 support dx 11.... i think it needs new cards entirely .

[desiibond]

HD4670 will not support DX11 but DX11 games will definitely be compatible with HD4670 and they will run in DX10 mode. Just like current DX10 games running in DX9 mode in XP or DX9 hardware.

[comp@ddict]

LOL, otherwise no one would have ever upgraded from a 9800PRO


AMD Details ATI Catalyst 9.8
AMD today made ATI Catalyst 9.8 driver suite available to the masses through its proper channel of posting it on the AMD Game portal, complete with related documentation. The company released the software last friday to readers of the company blog, just so it could loosely coincide with the bulk of activity during Quakecon 2009, when the company also carried out a series of private demonstrations of its upcoming DirectX 11 compliant graphics hardware to sections of the media.

Catalyst 9.8 has an unusually long changelog this time around, which can be attributed to two important changes: a series of CrossFireX performance enhancements that are game-specific, and the inclusion of OpenGL 3.1 support.

Performance Enhancements:

• Battleforge DirectX 10/DirectX 10.1 performance improves up to 15-50% in CPU limited settings with the largest gains in CrossfireX configurations.
• Company of Heroes DirectX 10 performance improves by up to 10-77% in CPU limited settings.
• Crysis DirectX 10 Dual CrossfireX performance improves as much as 10% and Quad CrossfireX performance improves as much as 34% in CPU limited settings.
• Crysis Warhead DirectX 10 Dual CrossfireX performance improves as much as 7% and Quad CrossfireX performance improves as much as 69% in CPU limited settings.
• Far Cry 2 DirectX 10 Dual CrossfireX performance improves as much as 50% and Quad CrossfireX performance improves as much as 88% in CPU limited settings.
• Tom Clancy's H.A.W.X. DirectX 10/DirectX 10.1 Dual CrossfireX performance improves up to 40% in CPU limited settings with Quad CrossfireX performance improving up to 60%.
• UnigineTropics OpenGL performance improves 5-20%
• UnigineTropics DirectX 10 Quad CrossfireX performance improves 5-20% in CPU limited settings.
• World in Conflict DirectX 10 performance improves by 5-10%.

OpenGL 3.1 Support

• Support for OpenGL Shading Language 1.30 and 1.40.
• Instanced rendering with a per-instance counter accessible to vertex shaders (GL ARB draw instanced).
• Data copying between buffer objects (GL EXT copy buffer).
• Primitive restart (NV primitive restart). Because client enable/disable no longer exists in OpenGL 3.1, the PRIMITIVE RESTART state has become server state, unlike the NV extension where it is client state. As a result, the numeric values assigned to PRIMITIVE RESTART and PRIMITIVE RESTART INDEX differ from the NV versions of those tokens.
• At least 16 texture image units must be accessible to vertex shaders, in addition to the 16 already guaranteed to be accessible to fragment shaders.
• Texture buffer objects (GL ARB texture buffer object).
• Rectangular textures (GL ARB texture rectangle).
• Uniform buffer objects (GL ARB uniform buffer object).
• SNORM texture component formats.

AMD Expected to Launch DX11 GPU on Sept. 10


Could the ATI DirectX 11 card be launching on September 10? Could be!



Earlier this year during June, AMD demonstrated at Computex the first DirectX 11 GPU, and most recently at Quakecon, the chip maker is showing off its latest silicon once again.

Expreview got a hold of an AMD presentation from Quakecon that reads, "On Thursday, September 10, 2009, you won't believe your eyes… Please join us as we unveil a new PC experience. Formal invitation with more details to come."

Given the timing of the slide and the recent demonstration of the ATI "Evergreen" DX11 hardware, it's a safe assumption that AMD will be launching something next month.

[desiibond]

^^yes. they are going to release DX11 cards so that they can have a good headstart against nVidia and also be ready for win7 retail release.

Not worth, triple slot, and WTF with an HD 4870?

[desiibond]

It's just the beginning for them

AMD ''Juniper'' ASIC Pictured

The cooler resembles the one found on Radeon HD 4770 (reference), and Radeon HD 3870, albeit opaque black. With the 40 nm GPU running presumably cool, its air vent on the rear panel is reduced in size, and makes way for an arsenal of connectivity that includes two DVI-D connectors, and one each of HDMI and DisplayPort, just as pictured earlier. The PCB is black in color, holds memory on either sides. The card draws its power from one 6-pin PCI-E power connector. Expect a lot more about this as we head toward September 10, when AMD plans to unveil its next-generation GPU technology. Juniper is part of AMD's "Evergreen" family of DirectX 11 compliant GPUs.

Waiting for DX11 GPU ( & windows 7 Final release ). I wish if they could come under under 10K & a DX11 GPu from nvidia ( that will make the competition fine ). Finger-crossed

[comp@ddict]

The top end HD5870 will end up at 249 or 299$ price.
