Despite the fact that the official sales of Intel Core processors 11 generation (Rocket Lake-S) for desktop processors have not yet started, some online stores have not only added them to their catalogs, but also launched on sale. In particular, if desired, you could buy a Core i7-11700K. And one of these CPUs has been fully tested.

For starters, the characteristics. The Core i7-11700K has eight processing cores and supports multithreading. The cache memory of the second level was 4 MB, of the third level – 16 MB. TDP is 125W, DDR4-3200MHz memory is supported.

The base frequency is 3.6 GHz, the maximum frequency with two active cores is 5.0 GHz, and with all active cores – 4.6 GHz. The CPU supports direct connection of video cards and SSDs via PCIe 4.0 – with 16 and 4 lanes, respectively. It also has an integrated Intel Xe-LP graphics core with 32 execution units.

Power consumption and heating tests were performed with different applications using different sets of instructions. Under normal conditions, the processor temperature was 60 ° C, and the power consumption was 130-155 W. Of course, this is more than the declared TDP value, but not much.

But it is enough to run an application designed for AVX2 instructions, and the TDP has already reached 225 watts. And executing the AVX-512 instructions is generally a stress test: with temperatures up to 104 ° C at peak and energy consumption of 292 W! For reference: during the test, the CPU was cooled with a conventional cooler with a fan, heatsink and several heat pipes. In terms of power consumption, the Core i7-11700K makes no sense to compare with the AMD Ryzen 7 5800X – the AMD processor against its background is cold as ice.

In normal applications and games, the Core i7-11700K is also not a competitor to the AMD Ryzen 7 5800X, which clearly follows from the graphs below. Moreover, the performance of the new product is practically the same as that of the current Core i7-10700K model.

There is an assumption that the problem with the Core i7-11700K lies in the organization of the L3 cache. More precisely, in increased time delays. But so far this is only an assumption. In addition, Intel is still finalizing the Rocket Lake microcode, so, perhaps, by the beginning of official sales, the CPU performance will still slightly increase.

But while the Core i7-11700K looks very pale compared to the AMD Ryzen 7 5800X. And even if the performance gets slightly higher, nothing makes up for the huge difference in power consumption between these CPUs. So after the release of the Core i7-11700K, the Ryzen 7 5800X will continue to be a better buy.

Intel introduced Arc Pro A40 and Arc Pro A50 graphics

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.

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.

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.

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.

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 worlds 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.

Japan has developed the world's fastest quantum processor

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.

AsRock tested its own Arc A380 graphics card and boasted

AsRock recently introduced its new Challenger ITX graphics card based on the Arc A380 graphics chip. And now, without postponing the matter indefinitely, I made a review on it.

AsRock tested its own Arc A380 graphics card and boasted the results

According to the manufacturer, this is a factory overclocked card with a GPU clock speed of 2250 MHz. However, in real tests it came out. For example, in the Furmark stress test, it reaches 2300 MHz, and in games – 2450 MHz.

Under full load, the fan speed reaches 1683 rpm and the chip temperature is 85°C. The power of the board, according to Furmark, is 54.9 W, which is less than the reference version of the Arc A380, where the TDP is 75 W.

In addition to benchmarks, ASRock has also tested the performance of several games, including popular AAA titles and modern DirectX12 API games. Testing was conducted at 1080p resolution.
