The first is the "GeForce GTX 570" and "GeForce GTX 560", all of which are said to be based on an improved version of the GF104 core and are positioned similarly to the GTX 470/460, but will wait until the latter's chip inventory is emptied before it is rolled out, which is their recent price cuts. One of the reasons. The release date is not yet set. As early as the end of this year, it will be late next year.
Then there are "GeForce GT 540" and "GeForce GT 520" for the mainstream and low-end markets. The specific specifications are ignorant. It is almost certain that it will not be available until 2011.
In fact, in addition to GF110, we have heard of development code names such as GF112, GF114, and GF119 before. It is no doubt that they represent the GeForce 500 series, but it is not yet possible to match them and there is no exact specification message.
As for the dual-core version, the legend has been repeated for a long time, but it has never been formed. The latest version is that NVIDIA is ready to use two improved versions of the GF100 core (similar to the GF104), and strive to get it out as soon as possible in December of this year to combat the debut of the AMD Antilles Radeon HD 6990, but power consumption is still a big problem Thermal design power is likely to approach an astonishing 400W, so it will also miscarry.
By the way, the performance of the GeForce GTX 580 is secretly exposed. According to the information we received today, GTX 580's game performance is up to 20% higher than GTX 480, and 3DMark Vantage's score is nearly 30% higher, which basically accords with the previous increase of 20-30%.
Overall, the pace of the GeForce 500 series seems to be moving very fast, which proves that NVIDIA's R & D speed also means that the GeForce 400 series will have a very short life span and will be gradually replaced in the first half of next year. After years of reviewing history, the GeForce 400 Series will surely become the most unwilling generation to be mentioned, just like the GeForce FX 5000.
LED PCB
As printed circuit board technology has continued to evolve, it has paved the way for the creation of a host of exciting product innovations. A prime example is the development of the PCB for LED lighting. The LED is soldered to the circuit board and features a chip that produces the light when electrically connected. A thermal heat sink and a ceramic base are used to bond the chip.
An LED PCB board tends to generate a high volume of heat, making it difficult to cool via traditional means. Consequently, metal core PCBs are frequently chosen for LED application due to their enhanced ability to dissipate heat. Aluminum in particular is often used to manufacture circuit boards for LED lights. The Aluminum PCB typically includes a thin layer of thermally conductive dielectric material that can transfer and dissipate the heat with much greater efficiency than a traditional Rigid PCB.
PCB LED Applications
PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility. Examples include Automotive headlights, Airport runway landing lights, Lighting used in military field applications, Street lighting, Highway tunnel lighting, Photovoltaic (solar) lighting, Flashlights and lanterns, Traffic and signal lighting, Lighting in hospital operating rooms, High growth plant lighting and many others.
