As we reported today, the latest Mars rover Perseverance, which recently landed on the Red Planet, is based on the RAD750 processor, which is a special version of the PowerPC 750 – the heart of the iMac G3 over 20 years ago.
In fact, the use of RAD750 in the new rover has been known for a long time, but it was actively talked about only after the successful landing of Perseverance.
Moreover, the price of the RAD750 has now become known. It turned out that this very old and technically primitive processor costs 200,000 dollars!
The source received information directly from the processor manufacturer – BAE Systems. She added that this CPU is installed in more than 250 spacecraft. By the way, there are two such processors in the new rover – the second is the main backup system in case of failure of the main one.
Interestingly, the Ingenuity helicopter, which flew to Mars with Perseverance, is based on the Snapdragon 801 SoC, and uses Linux as the OS. We can say that a helicopter is thousands of times more productive than its larger satellite.
Probably, such a platform was needed to implement an autonomous piloting system, because, unlike a rover, Ingenuity will fly over Mars on its own. In addition, it is designed for a maximum of 30 sols (Martian days) of work, while Perseverance should work at least 90 sols, but previous NASA rovers have already shown that they can work many times longer.
The most powerful embedded AMD processors. Ryzen Embedded 5000 Not Shown Yet, But Already Available
Advantech unveiled AIMB-522 motherboard with unseen Ryzen Embedded 5000 embedded processors.
The motherboard itself is not of particular interest, but the CPUs are curious. If usually embedded CPUs are based on mobile devices and are noticeably inferior to desktop ones in all respects, then the Ryzen Embedded 5000 almost in everything corresponds to the usual consumer Ryzen 5000.
In total, the line includes four processors: Ryzen 5950E, Ryzen 5900E, Ryzen 5800E and Ryzen 5600E. At the same time, the younger two are almost identical to consumer counterparts, and the older two offer slightly fewer cores.
As you can see, the Ryzen 5950E has 12 cores versus 16 for the Ryzen 9 5950X. The Ryzen 5900E already has only two fewer cores than the Ryzen 9 5900X. But the base frequencies for older CPUs are exactly the same, although the maximum ones are not indicated.
The names of the CPUs are also valid here, as these are processors based on the Zen 3 architecture.
$870 OLED 2.8K 90Hz screen, Ryzen 7 6800H, three USB-C 3.2 Gen 2 ports, and slim aluminum chassis. Xiaomi Mi Notebook Pro 14 2022 Ryzen Edition available for order in China
Retail sales of the Xiaomi Mi Notebook Pro 14 2022 Ryzen Edition in China will start tomorrow, but the device is already available for pre-order. And it’s better to really hurry up, because pre-ordering the device will cost much less. For example, the base version with a Ryzen 5 6600H CPU, 16GB LPDDR5-6400MHz RAM, and a 512GB SSD is now available for $800 and retails for $960. The Ryzen 7 6800H pre-order version is $870, retail is $1,035.
Now all the key parameters of the laptop have become known. So, Mi Notebook Pro 14 2022 Ryzen Edition received an OLED display with a diagonal of 14 inches, a resolution of 2880 x 1800 pixels, a frame rate of 90 Hz and coverage of 100% of the DCI-P3 color space. For a model without a discrete GPU, there is a fairly powerful cooling system – with two fans and two heat pipes.
The interface connectors are represented by three USB-C 3.2 Gen 2. The device configuration also includes a backlit keyboard, a 56 Wh battery, and an all-metal case. The laptop is 14.9 mm thick and weighs 1.4 kg. The package includes a power supply with an output power of 100 W.
GeForce RTX 3090 Ti drops $1,000 in US price in a couple of months
The official cost of the GeForce RTX 3090 Ti in the US is $2,000, but the top models, with a more efficient cooling system and, moreover, overclocked, sold more. For example, the EVGA GeForce RTX 3090 Ti FTW3 cost $2,150. But now the price has fallen, and much.
There are three models in the EVGA RTX 3090 Ti FTW3 lineup, and the base (non-factory overclocked) is now available in the US for $1,150.
Interestingly, a month and a half ago, the very same $2,150 was asked for a video card, three weeks ago the cost dropped to $1,500, and now another reduction is $250. The other two models (already overclocked) of the series are also priced lower: the Ultra version in the US is offered for $1,200, and the Black version for $1,400.
