Engineers came up with a way to increase the cooling efficiency of processors by 700%

US engineers have come up with a new way to cool semiconductor products, which does not involve the use of a thermal interface. Conformal coating in laboratory conditions has demonstrated its high efficiency in comparison with traditional methods of heat removal.

Engineers came up with a way to increase the cooling efficiency of processors by 700%

Electronic devices heat up during operation, and the greater the power, the stronger the heating, all other things being equal. This problem is especially acute with the miniaturization of devices. Researchers at the University of Illinois at Urbana-Champaign have come up with a new efficient way to remove heat from semiconductor products.

Usually, a radiator is connected to the hottest places of the microcircuit through a thermal interface. For example, thermal paste. Instead, American scientists proposed to cover the entire device with a thin layer of polymer insulator, and “fill” it with a layer of copper on top, completely repeating the shape of the device. This conformal coating is in close contact with the device and effectively removes heat from it.

“We compared our coatings to standard heat dissipation methods. It turned out that our method dissipates 740% more power per unit volume.one of the researchers explained.

It is expected that in the future this invention will make electronic devices, including telephones and computers, more powerful and compact.

Up to 8 XE cores and 6 GB of memory

The database of the SiSoftware Sandra test package has fresh data on the upcoming Arc A40 Pro and Arc A50 Pro graphics cards. These are graphics accelerators for workstations that are designed for engineering tasks.

Up to 8 XE cores and 6 GB of memory

The A50 Pro has a full ACM-G11 GPU with 8 Xe cores (128 execution units/1024 FP32 cores), while the A40 Pro is likely to get a stripped-down version of the chip. The clock frequency is 2.45 GHz.

Both cards have 6 GB GDDR6 memory, indicating a 96-bit memory bus. In this regard, both models are similar to the Arc A380 mobile card, which has almost the same configuration.

Thus, the company continues to prepare its entry-level products. When high-performance gaming and professional solutions based on the ACM-G10 GPU will appear, it is not reported. It is also not yet clear whether the Arc A40 Pro and Arc A50 Pro cards will be available in retail or whether they will appear only as part of workstations.

Earlier, Intel introduced its first gaming graphics card for $150.

Named the likely date of the announcement of the mobile

Qualcomm has updated its 2022 product launch roadmap. And there, among other things, they indicated the likely date for the announcement of the flagship Snapdragon 8 Gen 2 processor. It is expected to be shown on the first day of the Snapdragon Summit event, which will be held from November 14 to 17.

Named the likely date of the announcement of the mobile

Qualcomm also announced the Snapdragon X70 5G modem that will be included with the Snapdragon 8 Gen 2. It is credited with download speeds of up to 10 Gbps, as well as new advanced features for working in fifth-generation networks.

The processor (SM8550) will be manufactured using TSMC’s 4nm process. It will use a three-cluster layout. The composition is expected to include one super-powerful Cortex X3 core, two productive Cortex-A720 and A710, as well as three energy-efficient Cortex-A510. An Adreno740 graphics accelerator is also expected.

It is assumed that the first smartphone based on the Snapdragon 8 Gen 2 processor will be Xiaomi 13, its presentation is expected before the end of 2022.

Are the recommended prices for modern video cards too high? Calculated how adapters are priced based on performance

Are the recommended prices for modern video cards too high

Current generation video cards have been heavily overpriced almost all the time due to scarcity and demand from miners. Now the prices are getting back to normal, but how normal are the prices that are recommended? The source decided to evaluate how fair these prices are in terms of performance.

The source took the GeForce RTX 3070 as a conditional standard, which, according to our colleagues, is fairly priced if we take 4K resolution.

As you can see, there is an even more profitable graphics card – GeForce RTX 3060 Ti. That is, it offers more than its price of $400. As for the rest of Nvidia’s cards, most of them have not gone far from the standard, offering 90-94% price match. But all high cards are heavily overvalued. The same GeForce RTX 3090 Ti, according to such calculations, should cost only $ 814, and not $ 2,000 at all.

As far as AMD cards are concerned, only the Radeon RX 6800 and 6800 XT can be distinguished here, which are very close to 100%. Also, the Radeon RX 6700 XT has a rate of 92%. The rest of the cards are significantly more overpriced, although no model falls short of the RTX 3090 Ti in this indicator, simply because even the RX 6950 XT is almost half the price.

It is worth mentioning separately that the source only evaluated performance in games, so all calculations are rather arbitrary. They do not take into account the non-gaming capabilities of video cards, the same huge amount of memory in top GeForces, the complexity of GPU and PCB production, and so on.
