Building a computer with a 24-core 5 GHz CPU and a passive cooling system? Now it’s possible – 35-watt Intel Raptor Lake-T CPUs are on sale in Europe
German retailer Caseking has begun offering low-power 35W Intel Raptor Lake-T processors to everyone. Such CPUs are mainly supplied to large PC builders, but this time they are also available to ordinary users. True, prices are higher than for standard processors of the Raptor Lake family.
For example, for the flagship 24-core Core i9-13900T they ask for 629 euros – 30 euros than for the i9-13900K. And although these CPUs are equal in terms of the number of cores, the frequencies of the Core i9-13900T are much lower – 1.1-5.3 GHz. But such a processor may well get by with a passive cooling system, although it is far from being the simplest one.
As for the prices for the rest of the CPUs of the 35-watt line, they look like this:
- 16-core 24-thread core i7-13700T – 439 euros;
- 14-core 20-thread Core i5-13600T – 289 euros;
- 14-core 20-thread Core i5-13500T – 265 euros;
- 10-core 16-thread Core i5-13400T – 255 euros;
- 4-core 8-thread Core i3-13100T – 145 euros.

Absolutely all Mac computers based on Apple Silicon have a serious GoFetch vulnerability that cannot be fixed at the silicon level
Vulnerabilities are found not only in AMD or Intel processors. A fresh vulnerability called GoFetch was found in Apple M single-chip systems for its Mac computers.
The vulnerability allows attackers to steal cryptographic information from the CPU cache by allowing the attacker to create a cryptographic key from the stolen data, allowing the application to access sensitive encrypted data.
This vulnerability is very dangerous because it completely neutralizes the side-channel encryption algorithm used to protect against side-channel or processor cache attacks.
In addition, there is no way to fix the vulnerability at the silicon level, meaning Apple cannot start producing chips without the vulnerability. But, as in other cases, it is possible to create a software patch, but it is not yet known what share of productivity will have to be paid for this.

In China, they “imported” Apple Mac Studio. The SZBOX FN60G mini PC with a volume of only 2.5 liters can install an Intel processor for the LGA1700 socket and GeForce RTX 4060
As reported by ITHome, the SZBOX FN60G mini-computer has been introduced in China, which with its aluminum body is very reminiscent of the Apple Mac Studio.
With a small volume of only 2.5 liters, inside you can install not only any Intel processor for the LGA1700 socket (the only limitation is TDP no more than 100 W), but also a discrete video card. The source talks about a “modified” GeForce RTX 4060 or AMD Radeon RX6600. We are probably talking about models for Mini-ITX cases.
On the inside of the motherboard (the chipset model is not reported) there are two slots for DIMM DDR5 RAM modules (maximum RAM – 64 GB), as well as two M.2 connectors for installing solid-state drives. The interface connectors are well demonstrated in the image below.
SZBOX FN60G is already on sale on Aliexpress, but the price is considerable – 745 euros.

It's as if the Core i9-14900K consumes 4W. Efficient Computer Fabrik architecture introduced, allowing for 100 times more energy efficient processors
Startup Efficient Computer has unveiled the Monza processor, which the company claims is nearly 100 times more energy efficient than general purpose processors on the market today.
The secret to this potentially revolutionary achievement lies in its reconfigurable architecture and software stack.
Current general purpose processors are too general purpose and waste the vast majority of their energy (>99%) on unimportant internal data movement and instruction management overhead. Scaling performance requires complex power-intensive optimizations that further increase power consumption. The inefficiency of these designs causes the battery to drain quickly, limiting the device's capabilities and requiring frequent recharging or battery replacement.
Efficient's new Fabric architecture is a unique approach to general-purpose computing that eliminates the excessive power overhead inherent in existing general-purpose computing architectures. The new Efficient architecture significantly improves the energy efficiency of chips, bringing computing capabilities to use cases that were previously not possible due to limited energy availability. For example, a smartwatch or wearable health device can last for weeks on a charge and support more sophisticated analysis of sensor data, while a remote sensing satellite can provide highly accurate data using the limited energy of a nanosatellite's small battery
The company notes that compared to modern GPUs, its chip consumes three orders of magnitude less energy. The Fabric architecture was developed through more than seven years of research at Carnegie Mellon University, and the company's website includes links to scientific papers.
The company provides very few technical details, and nothing is reported at all about the Monza test processor. Given the claims of a revolutionary breakthrough in energy efficiency, this is somewhat strange.
