Last week we wrote about the new cryptocurrency ChiaCoin, which does not require a video card to mine, and now the requirements for the computer that will be used for farming have become known. As it turned out, quite a simple PC is indispensable here.
The efficiency of farming depends on the speed and volume of the solid-state drive (in this case, it is correct to call it farming, not mining). The minimum size of NVMe SSD is 256GB, but in reality it is better to use SSDs larger than 1TB.
In ChiaCoin farming, HDDs are used to store data: the larger the volume of this subsystem, the more likely it is to receive a reward. Therefore, it is desirable to use a hard disk drive of considerable size – 8 TB or more.
Finally, RAM – for ChiaCoin mining, this is also a very important aspect. In the process of mining this cryptocurrency, large amounts of RAM are required, so the minimum here is 16 GB of RAM, and the recommended amount for mining to go efficiently is 32 GB of RAM.
In general, it turns out that only the memory of the computer used for mining ChiaCoin will have to spend at least $ 500. This, of course, is much less than what is required to buy some modern video card (the same GeForce RTX 3060 is twice as expensive), but still not a little.
The Core i9-13900K showed that the new Intel processors will have a lot more cache. But the Ryzen 7 5800X3D is still far away
Despite the fact that Intel Raptor Lake processors should be released only at the very end of the year, they are increasingly appearing in various benchmarks. Today, the top-end Core i9-13900K lit up in the tests.
The software data confirms early rumors that the new CPUs will have much more cache memory. In particular, the Core i9-13900K has a total (L2 and L3) of 68 MB of cache. Apparently, we are talking about 36 MB of L3 cache and 32 MB of L2 cache. To be more precise, only large cores will have L3 cache, and small ones will also have L2.
Presumably, each large Raptor Cove core will have 2MB of L2 cache and 3MB of L3 cache. And each cluster of small cores will have 4 MB and 3 MB, respectively. The new CPUs will have eight large cores, and 16 small ones if we are talking about top models. As a result, Raptor Lake will have 55% more cache than Alder Lake.
However, this will still be comparable only to the Ryzen 5000, which came out a year and a half ago, and Intel processors will still be far from models with 3D V-Cache.
Nvidia graphics cards are much more overpriced than AMD adapters. Comparison of current markups for 3D maps appeared
HardwareUnboxed decided to check out AMD’s recent statement that the company’s cards are more profitable than competitors. It turned out it was true.
If we are talking about the US market, then the markups for Radeon graphics cards are much lower there than for GeForce adapters. The former are on average 5% more expensive than the recommended price, while the latter are already 24% more expensive.
Of course, for each buyer it is more important how overpriced the card he is going to purchase. We can note the Radeon RX 6500 XT, which is on average 3% cheaper than the recommended price. The prices of the RX 6600 XT, RX 6750 XT, RX 6900 XT and RX 6950 XT also look great. But the RX 6800 and RX 6800 XT are respectively 31% and 23% more expensive than the recommended prices, which makes their purchase look pointless.
As for Nvidia cards, the RTX 3090 Ti and RTX 3080 Ti also boast a zero markup, but on the RTX 3060 Ti it is 40%, and in general, junior adapters are greatly overpriced, and the RTX 3050 has risen in price by 5 over the last month. %.
Huawei Watch D is presented in Europe – the first smart watch with a blood pressure monitor
Huawei today introduced the flagship smart watch Huawei Watch D to the international market. The main highlight of the model was the real-time blood pressure measurement function.
The watch originally debuted in China in December 2021 and will now be available in Europe and other regions. The European price is 449 euros.
Huawei Watch D is positioned by the manufacturer as the first smart watch with a built-in blood pressure monitor. According to the manufacturer, Huawei Watch D is six times smaller than conventional blood pressure devices. The watch is equipped with a mini-pump capable of generating pressure up to 40 kPa, which allows you to measure blood pressure up to 230 mmHg. This is equivalent to the range of traditional blood pressure monitors.
At the same time, Huawei Watch D is not only a blood pressure sensor, but also a watch with a pulse measurement function and an ECG sensor module.
In addition, the watch has more than 70 training modes and tracks important physiological parameters of the body. In addition to measuring blood pressure and heart rate, they analyze sleep quality, blood oxygen saturation SpO2, measure skin temperature, stress levels and many other indicators. The watch can work without recharging for up to seven days.
The watch is equipped with a 1.64-inch AMOLED screen with a resolution of 280 x 456 pixels, a 451 mAh battery. Supports NFC, Bluetooth 5.1, GPS. Water protection (IP68) is provided. The watch itself is based on HarmonyOS and can be paired with smartphones based on HarmonyOS 2, Android 6.0 and later, iOS 9.0 and later.
