Yesterday AMD officially unveiled its new Epyc 7003 server processors, and today it is Intel’s turn: the blue have finally officially unveiled their 11th generation Core processors for desktop computers, also known as Rocket Lake-S. Consider it a pure coincidence, but Intel is reporting exactly the same IPC gain over its predecessors as AMD yesterday – 19%.
For ordinary users, there is a lot of good news and one bad news. But let’s start with the good ones. In addition to a 19% increase in IPC, the performance of integrated GPUs increased by up to 50% (Rocket Lake-S uses GPUs based on Intel Xe architecture). The new products provide performance gains in deep learning tasks due to the proprietary Intel Deep Learning Boost tool and support for Vector Neural Network instructions.
But home users will be much more interested in the fact that Rocket Lake-S supports DDR4-3200 MHz RAM and 20 PCIe 4.0 interface lanes. Yes, yes, now the video card and fast SSD can be connected directly to the corresponding processor controller, bypassing the chipset. This increases the speed of at least a solid-state drive. It also supports Resizable BAR technology, HDMI 2.0, Thunderbolt 4 (as well as USB 3.2 Gen 2×2 with a bandwidth of 20 Gbps) and Wi-Fi 6E.
The new processors are faster than the old ones in games. Thus, the Core i9-11900K bypasses the Core i9-10900K in games such as Gears 5, Grid 2019, Microsoft Flight Simulator and Total War: Three Kingdoms by 8-14%. According to official data, in the same games, the Core i9-11900K is faster than the Ryzen 9 5900X, but its superiority is already slightly less – 3-11%.
There are currently 19 models in the Rocket Lake-S family with TDPs from 35 to 125 W, 6-8 cores and frequencies up to 5.3 GHz. Their characteristics are as follows:
And now it’s time for the bad news: CPUs have risen in price. Not all models and not much, but, for example, in the case of the flagship Core i9-11900K, the difference with its predecessor is $ 51. And this despite the fact that the Core i9-10900K is a ten-core and operates at the same high frequency. At the same time, it should be noted that the cost of the models of the Core i5 line has not changed.
Rocket Lake-S are designed to work with motherboards based on 500 series chipsets, but they are also backward compatible with current motherboards based on 400 series chipsets.
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.
AsRock tested its own Arc A380 graphics card and boasted the results
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.
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.
The results are:
- League of Legends (high quality): 166.9 FPS.
- CS:GO (high quality): 160.1 FPS
- DOTA2 (high quality): 146.2 FPS
- APEX Legends (medium quality): 91.5 fps
- PUBG (low quality: 83.1 fps)
- Eternal Calamity (medium quality): 62.3 fps
- The Division 2 (high quality): 53 fps
- Shadow of the Tomb Raider (high quality): 56 fps
- Cyberpunk 2077 (medium quality): 47.51 fps
- Gears of War 5 (high quality): 63.1 fps
- Watch Dogs: Legion (high quality): 49 fps
Earlier it was reported that PCs with A380 graphics cards will soon appear in Europe.
