Synology has announced the HAS5300 series of hard disk drives. These 3.5-inch drives with 12 Gb / s SAS are designed to meet the growing demand for high-performance, high-capacity, resilient storage systems.
The series includes models HAS5300-8T, HAS5300-12T and HAS5300-16T in 8, 12 and 16 TB sizes. They complement the Synology HAT5300 lineup, introduced in January, which includes 8, 12 and 16 TB SATA hard drives.
The spindle speed for all three HAS5300 models is 7200 rpm. The buffer capacity for the 8 and 12 TB models is 256 MiB, and for the 16 TB model it is 512 MiB. Maximum sustained data rates are 230, 242 and 262 MiB / s
The drives have a declared workload of up to 550 TB of transferred data per year and an MTBF of 2.5 million hours. The warranty period is five years.
AMD is preparing new packaging for Ryzen 7000 processors
An image of a new packaging for AMD Ryzen 7000 processors has appeared on the network. We are talking about expensive models. The source claims that such boxes will receive processors with a price tag of $500. Most likely, these will be Ryzen 9 models, while Ryzen 7 and Ryzen 5 may receive different packaging.
The announcement of new AMD processors is expected on August 29 at a separate event, and Ryzen 7000 will go on sale on September 15. It is assumed that the prices for them will not differ much from those set for the Ryzen 5000 series.
At the same time, the line will include both processors for the new AM5 socket, and, probably, models for AM4. Such processors are credited with supporting DDR4 RAM, while the main line only supports DDR5. The very fact of the release of such processors has not yet been officially confirmed, but rumors on this topic are circulating on the network.
It is possible that the company will release only a few new CPUs for the old socket, which will be positioned separately from the main line.
Intel introduced Arc Pro A40 and Arc Pro A50 graphics cards. But these are not the models that ordinary users and gamers are waiting for.
Everyone is waiting for real gaming graphics cards of the Arc line from Intel, but the company is in no hurry. But today, the range of Intel video cards has been replenished with two discrete models at once – Arc Pro A40 and Arc Pro A50. As the name suggests, they are designed for professional use. However, the characteristics are modest, so this most professional application will be limited.
Both models have 6GB of GDDR6 memory, support real-time ray tracing and AV1 hardware encoding, and feature four Mini DP 1.4 ports. Arc Pro A40 has a peak consumption of 50 W, this card is a single-slot version, Arc Pro A50 is a dual-slot version, and its peak consumption is 75 W. Performance in the first case is 3.5 TFLOPS with single precision, in the second – 4.8 TFLOPS. For comparison, the performance of the old Radeon HD 6970 (it came out at the end of 2010) is 2.7 TFLOPS.
Together with discrete solutions, the Intel Arc Pro A30M mobile GPU is also presented – it is in many ways similar to the Arc Pro A40, only there is less memory (only 4 GB GDDR) and the power consumption level is adjustable – from 35 to 50 watts. The new Intel GPUs will appear in off-the-shelf products later this year.
Japan has developed the world’s fastest quantum processor
Japanese physicists have created a two-qubit quantum processor with a record high speed. This was reported by the press service of the National Institute of Natural Sciences of Japan (National Institute of Natural Sciences – NINS). A group of scientists led by Professor Kenji Omori has created a processor based on Rydberg atoms. These particles play the role of qubits – quantum analogues of ordinary bits. This development was based on atoms of rubidium-87, cooled to near absolute zero and located at a distance of one micron from each other.
The last electron of such an atom is moved a long distance from the nucleus with the help of special pulses of laser radiation – ultrashort, but very powerful. Such pulses transfer neighboring atoms to the Rydberg state, make them interact and participate in the calculation of logical operations. As a result, the processor spends only 6.5 nanoseconds per operation, which is about a hundred times faster than previously achieved on other quantum computers based on cold atoms.
An important factor is the ability of the Japanese development to circumvent some of the limitations that exist for quantum computers. The accuracy of the calculations of quantum processors reduce noise from the external environment and the operating laser. But in this case, one logical operation is performed approximately two orders of magnitude faster than noise occurs in the operation of qubits. In theory, this allows you to ignore their effect on the computer. According to scientists, the new development will lead to the creation of quantum computers capable of performing hundreds of millions of operations per second.
