Physicists at the Harvard John A. Paulson School of Engineering and Applied Sciences have developed an ion processor that works like a brain—by moving ions in an aqueous solution rather than on electrons like solid semiconductors. The study is published in Advanced Materials.
The main condition for signaling in the brain is the movement of charged molecules, called ions, in solution. Although the incredible processing power of the brain is extremely difficult to replicate, scientists have suggested that a similar system could still be used for computing.
The authors created a transistor with a disc-shaped electrode in the center and two ring electrodes around it. They placed this structure in an aqueous solution of quinone molecules. When a voltage was applied to the central disk, a flow of hydrogen ions was created in the solution. Two ring electrodes made it possible to increase or decrease the current strength, thus adjusting the pH of the solution.
Using various system indicators, including the pH of the solution and the voltage across the transistor, arithmetic multiplication can be performed. And if you combine several transistors, you can perform the matrix multiplication necessary for the operation of neural networks. The scientists were able to demonstrate this for 16 by 16 matrices.
The technology has significant limitations. 16 threads cannot exist simultaneously, that is, all operations had to be performed sequentially, and not simultaneously, which significantly slowed down the already slow technology. However, the scientists have shown that their approach is viable, and now they plan to introduce more types of molecules into the system that will allow for more complex calculations.
Not as thick as new Nvidia graphics cards. Non-Reference XFX RX 7900 XT Merc 310 Image Revealed
XFX will offer non-reference 3D cards of the Radeon RX 7000 line. Images of the RX 7900 XT Merc 310 model have already appeared on the Web, but we can safely assume that there will also be a similar-looking RX 7900 XTX Merc 310.
The card is made in the usual XFX design. It is very long, but not the thickest by modern standards. It will probably take up less than three expansion slots.
You can also highlight three power connectors (8 + 8 + 8) and the absence of a USB-C port, which is available on new generation AMD reference adapters.
Recall that the RX 7900 will be launched on December 13th. On the same day, reviews of new AMD products will be published. If the new 3D cards prove to be very successful for their prices, Nvidia can reduce the price of the GeForce RTX 4080, because it is 20% more expensive than the top RX 7900 XTX.
Intel graphics cards are drastically faster in some older games. Intel has worked on support for DirectX 9
Intel Arc graphics cards, among other things, have rather mediocre performance in older games. But today the company has released a fresh driver that significantly changes the situation, although not in all games.
The company has worked on optimization for some specific games, adding native support for DirectX 9. In particular, it is important to note Counter-Strike: Global Offensive, in which the performance of Arc adapters increased by almost 80%. The company has also worked on the 1% percentile, increasing the rate by up to 2.3 times, which should make the gameplay smoother.
Not all old games have received an impressive performance boost, but Intel can still be commended for continuing to work on its accelerators.
The GeForce RTX 4080 12GB is back. First GeForce RTX 4070 Ti unveiled
Rumors that the GeForce RTX 4080 12GB video card, canceled right before the release, will return under the name GeForce RTX 4070 Ti have been fully confirmed. Colorful has completely declassified the RTX 4070 Ti BattleAx Deluxe 3D card, and its specs are exactly the same as those of the GeForce RTX 4080 12GB.
Although the cooler is different from the cooler that Nvidia equips its video cards with, the Colorful RTX 4070 Ti BattleAx Deluxe is the reference model in everything else. It is built on the AD104 GPU and has 12 GB of GDDR6X memory with a frequency of 21 GHz. The base frequency of the GPU is 2310 MHz.
There is only one connector for connecting additional power – a 16-pin one, to which GeForce RTX 4090 users have a lot of complaints. However, the consumption of the RTX 4070 Ti is significantly lower, so it is hardly worth worrying about the melting of the connectors in this case. Colorful doesn’t specify the number of CUDA cores, but it should be 7680, which is exactly what Nvidia claimed for the RTX 4080 12 GB.
According to preliminary data, sales of the GeForce RTX 4070 Ti will start on January 5, immediately after the formal official premiere on January 3.
