TechPowerUP.com – A real monster seems to be taking shape at NVIDIA. The company’s next big graphics processor looks like a leap ahead of anything current-generation, the way G80 was when it released. It is already learned that the GPU will use a new MIMD (multiple instructions multiple data) mechanism for its highly parallel computing, which will be physically handled by not 384, but 512 shader processors. The count is a 112.5% increase over that of the existing GT200, which has 240.
NVIDIA has reportedly upped the SP count per cluster to 32, against 24 for the current architecture, and a cluster count of 16 (16 x 32 = 512). Also in place, will be 8 texture memory units (TMUs) per cluster, so 128 in all. What exactly makes the GT300 a leap is not only the fact that there is a serious increase in parallelism, but also an elementary change in the way a shader processor handles data and instructions, in theory, a more efficient way of doing it with MIMD. The new GPU will be DirectX 11 compliant, and be built on the 40 nm manufacturing process. We are yet to learn more about its memory subsystem. The GPU is expected to be released in Q4 2009.
Guru3D.com – It is rumored that NVIDIA’s GeForce GT 300 new flagship graphics card won’t arrive until October this year, a source leak with one of NVIDIA’s partners may have hinted to this . They tell the Inquirer that the first actual production models will be ready October 15th following a tape out, or a first submission for manufacturing, in June.
Whether or not NVIDIA will make its target is nonetheless called into question. The company is likely to have the first revision of fully testable silicon on August 1st but may take as much as 3 months after testing to manufacture enough for the first batch, putting an actual release in mid-November at the soonest. Any need to significantly revise the card would likely push the actual release further. Read more…
Fudzilla.com is informing that they have managed to confirm that NVIDIA plans to release a DirectX 11 card by the end of the year.
” (…) All indicates that the card comes in the 40nm process, but we don’t know this for sure. This might very well mean that NVIDIA won´t really have anything new until Q4 2009 which might get boring, but at least NVIDIA will step up and embrace future technology.
NVIDIA did said before that it doesn’t plan to go for DirectX 10.1 and that it rather wants to concentrate on DirectX 11 but it was more of a business decision as ATI was leading with DirectX 10.1 for such a long time.
ATI will probably have its DirectX 11 card in the same timeframe. (…) ”
AMD nVidia and ATi are planning imminent entry into 40nm process technology. Which of these will be the first? It is not known, but on the network, the first information about the first 40-nanometer nVidia system.
GT218 (because it is to be named the new product) is to be an arrangement of low-end and cards using the GPU is likely to be produced on lowprile PCB. The system is to have a thirty two-stream processors, TMU eight individuals and four entities ROP. The reference clock is 550 / 1375 / 1600MHz (GPU / Shaders / RAM). GT 218 cards are to have 512MB of RAM DDR3 on 64-bit bus.
Presented system is to be the successor GeForce 9300. Production is likely to start in the second quarter of this year.
NVIDIA is working on a new graphics card, which will help in the fight against ATI and eventually take over the performance leader in high-end segment. Card called GT300 will be the first card that supports DirectX 11 The manufacturer as is the custom to shoot on the market in the ultra high-end, and only at a later date cards budget.
We know that ATI should be high-end card with DirectX 11w similar time and in time between the two companies will focus on lower-cost solutions to their existing cards.
For technical details still too early, but the war vs NVIDIA. ATI performance graphics systems will certainly fierce.
hardware-infos.com – For industry-related circles, we have insight info of the ongoing NVIDIA plans and thereby create an overview of what the Californian graphics specialists soon to be expected. It had, among other things, surprisingly, found that NVIDIA in the end of 2009 will launch the GT3xx-generation DirectX 11 cards. Sooner they will try to remain GT2xx-GT206, GT212 and GT216 competitive. Following an overview of the current NVIDIA plans:
- GT206: Q4/2008, 55 nm
- GT212: Q1/2009, 40 nm
- GT216: Q2/2009, 40 nm
- GT300: Q4/2009, 40 nm

First specifications of GeForce 350 GTX have been leaked (unfortunately it is not known if they are true).
New weapons of NVIDIA are based on the core GT300. Its made in 55nm technology process, system is equipped with innovations such as unified units which are doubled in amount (now 480), plus (2GB) and accelerated (GDDR5) video memory, and also raised clocks: core – 830 MHz, a unified shaders – 2075 MHz and memory – 1680 (3360) MHz. Memory clocks have not changed and still with a width of 512 bits. Contrary to the expectations of the new GeForce still will not be compatible with DirectX 10.1.
Rumors say that new GeForce GTX 350 will be 30% faster than GeForce GTX 280.
Internet leaks show that in the end of this year market will welcome new NVIDIA graphics card, which has all chances to threaten the current leader, Radeon 4870 X2 from ATI. It will be a high-end GeForce GTX 350, and it boards new chip – GT300, manufactured in 55 nm process technology.
The new GPU will consist of 480 stream processors (formerly leader GT200, includes 240), 64 texture units and 512-bit memory controller. The core GT300 is to be at clock 830 MHz, 2075 MHz shader processors, and memory (GDDR5) – 3360 MHz. In the specifications that GeForce GTX 350 should be more than 50% faster than the current GT200, and this means that it will smash Radeon 4870 X2.
The exact release date or price of a new NVIDIA product is not yet known. GeForce GTX 350, but will certainly not cheap, however, you can expect that it will be for Christmas can be purchased for around 760 $.
EDIT: Rumors say that GT300 core will not support DirectX 10.1
